What is Human Development?

While the expression “human development” is widely used, it is understood in different ways around..

HDRO Outreach

2015 marks 25 years since the first Human Development Report introduced a new approach for advancing human flourishing. And while the expression “human development” is widely used, it is understood in different ways around the world. So on the occasion of the 25th anniversary year of human development reporting, we’d like to highlight how the Human Development Report Office (HDRO) presents human development.

Human development grew out of global discussions on the links between economic growth and development during the second half of the 20th Century. By the early 1960s there were increasingly loud calls to “dethrone” GDP: economic growth had emerged as both a leading objective, and indicator, of national progress in many countries i , even though GDP was never intended to be used as a measure of wellbeing ii . In the 1970s and 80s development debate considered using alternative focuses to go beyond GDP, including putting greater emphasis on employment, followed by redistribution with growth, and then whether people had their basic needs met.

These ideas helped pave the way for the human development approach, which is about expanding the richness of human life, rather than simply the richness of the economy in which human beings live. It is an approach that is focused on creating fair opportunities and choices for all people. So how do these ideas come together in the human development approach?

• People: the human development approach focuses on improving the lives people lead rather than assuming that economic growth will lead, automatically, to greater opportunities for all. Income growth is an important means to development, rather than an end in itself.

• Choices: human development is, fundamentally, about more choice. It is about providing people with opportunities, not insisting that they make use of them. No one can guarantee human happiness, and the choices people make are their own concern. The process of development – human development - should at least create an environment for people, individually and collectively, to develop to their full potential and to have a reasonable chance of leading productive and creative lives that they value.

The human development approach, developed by the economist Mahbub Ul Haq, is anchored in Amartya Sen’s work on human capabilities, often framed in terms of whether people are able to “be” and “do” desirable things in life iii . Examples include

Beings: well fed, sheltered, healthy

Doings: work, education, voting, participating in community life.

Freedom of choice is central: someone choosing to be hungry (during a religious fast say) is quite different to someone who is hungry because they cannot afford to buy food.

As the international community seeks to define a new development agenda post-2015, the human development approach remains useful to articulating the objectives of development and improving people’s well-being by ensuring an equitable, sustainable and stable planet.

What is Development?

Human Development or Lifespan Development is the scientific study of the ways in which people change, as well as remain the same, from conception to death. You will discover that the field, known more broadly as developmental science , examines changes and stability across multiple domains of psychological and social functioning. These include physical and neurophysiological processes, cognition, language, emotion, personality, moral, and psychosocial development, including our relationships with others.

Originally concerned with infants and children, the field has expanded to include adolescence and more recently, aging and the entire life span. Previously, the message was once you are 25, your development is essentially completed. Our academic knowledge of the lifespan has changed, and although there is still less research on adulthood than on childhood, adulthood is gaining increasing attention. This is particularly true now that the large cohort known as the “baby boomers” are beginning to enter late adulthood. The assumption that early childhood experiences dictate our future is also being called into question. Instead, we have come to appreciate that growth and change continues throughout life and experience continues to have an impact on who we are and how we relate to others. We now recognize that adulthood is a dynamic period of life marked by continued cognitive, social, and psychological development.

You will also discover that developmental psychologists investigate key questions, such as whether children are qualitatively different from adults or simply lack the experience that adults draw upon. Other issues they consider include the question of whether development occurs through the gradual accumulation of knowledge or through qualitative shifts from one stage of thinking to another, or if children are born with innate knowledge or figure things out through experience, and whether development is driven by the social context or something inside each child. From these questions, you may already be thinking that developmental psychology is related to other applied fields. You are right. Developmental science informs many applied fields, including, educational psychology, developmental psychopathology, and intervention science. It also complements several other basic research fields in psychology including social psychology, cognitive psychology, and cross-cultural psychology. Lastly, it draws from the theories and research of several scientific fields including biology, sociology, health care, nutrition, and anthropology.

Learning Objectives: Lifespan Perspective

• Explain the lifespan perspective and its assumptions about development
• Differentiate periods of human development
• Identify key assumptions and major meta-theories underlying lifespan development 
• Identify major historical and contemporary theories focusing on lifespan development

Lifespan Perspective

Paul Baltes identified several underlying principles of the lifespan perspective (Baltes, 1987; Baltes, Lindenberger, & Staudinger, 2006).

• Development is lifelong . Lifespan theorists believe that development is life-long, and change is apparent across the lifespan. No single age period is more crucial, characterizes, or dominates human development. Consequently, the term lifespan development will be used throughout the textbook.
• Development is multidirectional and multidimensional.  Lifespan researchers hold that different people follow different developmental pathways, and proceed along pathways at different rates. Even within the same person, different dimensions or domains of development can change in different ways.
• Development includes both gains and losses . Lifespan theorists do not agree with the traditional view of development that childhood is a period characterized by developmental gains, whereas old age is a time of loss. Instead, the lifespan approach holds that at every age, we may show gains in some areas of development, while showing losses in other areas. Every change, whether it is finishing high school, getting married, or becoming a parent, entails both growth and loss.
• Development is characterized by plasticity. Plasticity is about malleability , or our potential to change and to follow a wide range of developmental pathways.  For instance, plasticity is illustrated in the brain’s ability to learn from experience and the many ways it can recover from injury.
• Development is embedded in historical and cultural contexts. Lifespan researchers believe that d evelopment is influenced by the many social contexts in which it unfolds. How  people develop will depend on their societal and cultural contexts, and on the historical period during which their development takes place.
•   Development is multiply determined. Lifespan theorists argue that development is caused by multiple factors, and is always shaped by  both biological and environmental factors. In addition, the individual plays an active role in their own development.
• Development is multidisciplinary. As mentioned at the start of the chapter, human development is such a vast topic of study that it requires the theories, research methods, and knowledge bases of many academic disciplines.

Contextualism as paradigm.  Baltes (1987) identified three specific developmental systems of influence, all of which include biological and environmental forces.

• Normative age-graded influences: An age-grade is a specific age group, such as toddler, adolescent, or senior . Humans experience particular age-graded social experiences (e.g., starting school) and biological changes (e.g., puberty).
• Normative history-graded influences: The time period in which you are born (see Table 1.1) shapes your experiences. A cohort is a group of people who are born at roughly the same period in a particular society. These people travel through life often experiencing similar historical changes at similar ages. History-graded influences include both environmental determinants (e.g., historical changes in the job market) and biological determinants (e.g., historical changes in life expectancy).
• Non-normative influences : People’s development is also shaped by specific influences that are not organized by age or historical time, such as immigration, accidents, or the death of a parent. These can be environmental (e.g., parental mental health issues) or biological (e.g., life threatening illness).

Domains of development. We change across three general domains/dimensions; physical, cognitive, and psychosocial. The physical domain includes changes in height and weight, sensory capabilities, the nervous system, as well as the propensity for disease and illness . The cognitive domain encompasses the changes in intelligence, wisdom, perception, problem-solving, memory, and language. The psychosocial domain focuses on changes in emotion, self-perception and interpersonal relationships with families, peers, and friends. All three domains influence each other. It is also important to note that a change in one domain may cascade and prompt changes in the other domains. For instance, an infant who has started to crawl or walk will encounter more objects and people, thus fostering developmental change in the child’s understanding of the physical and social world.

Contextual perspectives , like the lifespan approach, highlight societal contexts that influence our development. An important societal factor is our social standing, socioeconomic status, or social class. Socioeconomic status (SES) is a way to identify families and households based on their shared levels of education, income, and occupation. While there is certainly individual variation, members of a social class tend to share similar privileges, opportunities, lifestyles, patterns of consumption, parenting styles, stressors, religious preferences, and other aspects of daily life. All of us born into a class system are socially located, and we may move up or down depending on a combination of both socially and individually created limits and opportunities.

Families with higher socioeconomic status usually are in occupations (e.g., attorneys, physicians, executives) that not only pay better, but also grant them a certain degree of freedom and control over their job. Having a sense of autonomy or control is a key factor in experiencing job satisfaction, personal happiness, and ultimately health and well-being (Weitz, 2007). Those families with lower socioeconomic status are typically in occupations that are more routine, more heavily supervised, and require less formal education. These occupations are also more subject to job disruptions, including lay-offs and lower wages.

Poverty level is an income amount established by the federal government that is based on a set of thresholds that vary by family size (United States Census Bureau, 2016). If a family’s income is less than the government threshold, that family is considered in poverty. Those living at or near poverty level may find it extremely difficult to sustain a household with this amount of income. Poverty is associated with poorer health and a lower life expectancy due to poorer diet, less healthcare, greater stress, working in more dangerous occupations, higher infant mortality rates, poorer prenatal care, greater iron deficiencies, greater difficulty in school, and many other problems. Members of higher income status may fear losing that status, but the poor may have greater concerns over losing housing.

Today we are more aware of the variations in development and the impact that culture and the environment have on shaping our lives. Culture is the totality of our shared language, knowledge, material objects, and behavior. It includes ideas about what is right and wrong, what to strive for, what to eat, how to speak, what is valued, as well as what kinds of emotions are called for in certain situations. Culture teaches us how to live in a society and allows us to advance because each new generation can benefit from the solutions found and passed down from previous generations. Culture is learned from parents, schools, houses of worship, media, friends and others throughout a lifetime. The kinds of traditions and values that evolve in a particular culture serve to help members function and value their own society. We tend to believe that our own culture’s practices and expectations are the right ones. This belief that our own culture is superior is called ethnocentrism and is a normal by-product of growing up in a culture. It becomes a roadblock, however, when it inhibits understanding of cultural practices from other societies. Cultural relativity is an appreciation for cultural differences and the understanding that cultural practices are best understood from the standpoint of that particular culture.

Culture is an extremely important context for human development and understanding development requires being able to identify which features of development are culturally based. This understanding is somewhat new and still being explored. Much of what developmental theorists have described in the past has been culturally bound and difficult to apply to various cultural contexts. The reader should keep this in mind and realize that there is still much that is unknown when comparing development across cultures.

Lifespan vs. Life expectancy: At this point you must be wondering what the difference between lifespan and life expectancy is, according to developmentalists. Lifespan , or longevity, refers to the maximum age any member of a species can reach under optimal conditions . For instance, the grey wolf can live up to 20 years in captivity, the bald eagle up to 50 years, and the Galapagos tortoise over 150 years (Smithsonian National Zoo, 2016). The longest recorded lifespan for a human was Jean Calment who died in 1994 at the age of 122 years, 5 months, and 14 days (Guinness World Records, 2016). Life expectancy is the average number of years a person born in a particular time period can typically expect to live (Vogt & Johnson, 2016).

Conceptions of Age

How old are you? Chances are you would answer that question based on the number of years since your birth, or what is called your chronological age . Ever felt older than your chronological age? Some days we might “feel” like we are older, especially if we are not feeling well, are tired, or are stressed out. We might notice that a peer seems more emotionally mature than we are, or that they are physically more capable. So years since birth is not the only way we can conceptualize age.

Biological age: Another way developmental researchers can think about the concept of age is to examine how quickly the body is aging , this is your biological age . Several factors determine the rate at which our body ages. Our nutrition, level of physical activity, sleeping habits, smoking, alcohol consumption, how we mentally handle stress, and the genetic history of our ancestors, to name but a few.

Psychological age: Our psychologically adaptive capacity compared to others of our chronological age is our psychological age . This includes our cognitive capacity along with our emotional beliefs about how old we are. An individual who has cognitive impairments might be 20 years of age, yet has the mental capacity of an 8-year-old. A 70- year-old might be travelling to new countries, taking courses at college, or starting a new business. Compared to others of our age group, we may be more or less active and excited to meet new challenges. Remember you are as young or old as you feel.

Social age: Our social age is based on the social norms of our culture and the expectations our culture has for people of our age group . Our culture often reminds us whether we are “on target” or “off target” for reaching certain social milestones, such as completing our education, moving away from home, having children, or retiring from work. However, there have been arguments that social age is becoming less relevant in the 21st century (Neugarten, 1979; 1996). If you look around at your fellow students at college you might notice more people who are older than traditional aged college students, those 18 to 25. Similarly, the age at which people are moving away from the home of their parents, starting their careers, getting married or having children, or even whether they get married or have children at all, is changing.

Those who study lifespan development recognize that chronological age does not completely capture a person’s age. Our age profile is much more complex than this. A person may be physically more competent than others in their age group, while being psychologically immature. So, how old are you?

Table 1.2 Age Periods of Development

Table 1.2 shows the developmental periods that will be explored in this book, starting with prenatal development and continuing thought late adulthood to death. Both childhood and adulthood are divided into multiple developmental periods. So, while both an 8-month old and an 8-year-old are considered children, they have very different motor abilities, social relationships, and cognitive skills. Their nutritional needs are different and their primary psychological concerns are also distinctive. The same is true of an 18-year-old and an 80-year-old, even though both are considered adults.

Prenatal Development : Conception occurs and development begins. All of the major structures of the body are forming, and the health of the mother is of primary concern. Understanding nutrition, teratogens , or environmental factors that can lead to birth defects , and labor and delivery are primary concerns.

Infancy and Toddlerhood : The first two years of life are ones of dramatic growth and change. A newborn, with a keen sense of hearing but very poor vision, is transformed into a walking, talking toddler within a relatively short period of time. Caregivers are also transformed from someone who manages feeding and sleep schedules to a constantly moving guide and safety inspector for a mobile, energetic child.

Early Childhood: This period is also referred to as the preschool years and consists of the years that follow toddlerhood and precede formal schooling. As a two to six-year-old, the child is busy learning language, gaining a sense of self and greater independence, and  beginning to understand the workings of the physical world.

Middle and Late Childhood: The ages of six to the onset of puberty comprise middle and late childhood, and much of what children experience at this age is connected to their involvement in the early grades of school. Now the world becomes one of learning and testing new academic skills, and assessing one’s abilities and accomplishments by making comparisons between self and others.

Adolescence : Adolescence is a period of dramatic physical change marked by an overall growth spurt and sexual maturation, known as puberty . It is also a time of cognitive change as the adolescent begins to think of new possibilities and to consider abstract concepts such as love, fear, and freedom. At the same time, adolescents have a sense of invincibility that puts them at greater risk of accidents or contracting sexually transmitted infections that can have lifelong consequences.

Emerging Adulthood: The period of emerging adulthood is a transitional time between the end of adolescence and before individuals acquire all the benchmarks of adulthood. Continued identity exploration and preparation for full independence from parents are negotiated. Although at one’s physiological peak, emerging adults are most at risk for involvement in violent crimes and substance abuse.

Early Adulthood : The twenties and thirties are identified as early adulthood. Intimate relationships, establishing families (of all shapes and sizes), and work are primary concerns at this stage of life.  For adults with children, developmental changes can become organized around the family life cycle.

Middle Adulthood : The forties through the mid-sixties are referred to as middle adulthood. This is a period in which aging becomes more noticeable and when many people are at their peak of productivity in love and work.  At this age, some people are negotiating adolescent children and aging parents at the same time.

Late Adulthood : Late adulthood is sometimes subdivided into two categories: The young-old who are from 65-84 years and the oldest-old who are 85 years and older. One of the primary differences between these groups is that the young-old are still relatively healthy, productive, active, and the majority continue to live independently. With both age groups the risks of diseases such as arteriosclerosis, cancer, and cerebral vascular disease increase substantially.

Meta-theories of Human Development

The study of development is guided by the assumptions researchers hold about the nature of humans and their development. These assumptions are called meta-theories . “Meta” means “above” or “beyond,” like “meta-physics.” Other terms used to describe meta-theories are “world views,” “cosmologies,” “perspectives,” or “paradigms,” as in “paradigm shifts.” Explicit discussions of meta-theories are found most often in philosophy.

What are meta-theories of human development?

Meta-theories (or world views or paradigms) of human development are sets of assumptions people hold about the nature of humans and the meaning of development — what it looks like, how it happens, what causes it. These assumptions are important because everyone has them, including researchers, but they are often implicit, meaning we are not always consciously aware of them. In the study of development, such assumptions influence everything about how research is conducted: the questions we ask, the measures and methods that are used, and the interpretation of data. For example, if researchers assume that development ends at 18, they do not look for developmental changes after that age. Or, if researchers assume that aging is a process of decline, then they never look for characteristics that might improve as people get older.

All researchers have meta-theories, since assumptions are baked into the theories and methodologies they use. But researchers are often unaware of them, and so these assumptions are rarely acknowledged. It is important to note that meta-theories are not just cold cognitions. They are often deeply held convictions that researchers will fiercely defend. Typically researchers think that their assumptions are self-evident truths. They are often convinced that their assumptions are right and everyone else’s are wrong.

Researchers holding different meta-theories can have difficulty communicating with each other. Since they are asking different questions and using different truth criteria for research, they often argue past each other or misunderstand each other. One group of researchers will offer what they consider to be irrefutable proof of their ideas, which other researchers then dismiss as irrelevant. Discrepancies, inconsistencies, arguments, and furor often characterize an area of study in which researchers from multiple meta-theories are working.

What kinds of assumptions guide the study of human development?

We consider six key assumptions. You may have heard of many of them, since they are perennial issues in the study of development. They include:

• Assumptions about human nature : whether people are born as blank slates ( tabula rasa ) or whether people are inherently good or inherently bad.
• Assumptions about the causes of development : whether development is determined by nature (genes, biology) or determined by nurture (environment, learning).
• Assumptions about the role of the individual in his or her own development: whether people are passive participants, reacting to external forces or whether they are active in choosing and shaping their own development.
• Assumptions about stability vs. change : whether traits, characteristics, and experiences early in life have permanent effects or whether people are malleable and open to change throughout life.
• Assumptions about continuity vs. discontinuity : whether development involves quantitative incremental change or qualitative shifts.
• Assumptions about universality vs. context specificity : whether development follows a universal pathway or depends more on specific experiences and environmental contexts.

Nature of humans. What is the nature of humans? These assumptions refer to beliefs about the underlying qualities of our species– whether humans are born as blank slates ( tabula rasa ) or whether we all bring intrinsic human characteristics with us into the world. For example, these different assumptions are readily apparent in alternative conceptualizations of motivation—some theories assume that motives and motivation are all acquired, whereas others assume that all humans come with intrinsic motivations.

Nature and Nurture: Why are you the way you are? As you consider some of your features (height, weight, personality, being diabetic, etc.), ask yourself whether these features are a result of heredity or environmental factors, or both. Chances are, you can see the ways in which both heredity and environmental factors (such as lifestyle, diet, and so on) have contributed to these features. For decades, scholars have carried on the “nature/nurture” debate. For any particular feature, those on the side of nature would argue that heredity plays the most important role in bringing about that feature. Those on the side of nurture would argue that one’s environment is most significant in shaping the way we are. This debate continues in all aspects of human development, and most scholars agree that there is a constant interplay between the two forces. It is difficult to isolate the root of any single behavior as a result solely of nature or nurture.

Active versus Passive: How much do you play a role in your own developmental path? Are you at the whim of your genetic inheritance or the environment that surrounds you? Some theorists see humans as playing a much more active role in their own development. Piaget, for instance believed that children actively explore their world and construct new ways of thinking to explain the things they experience. In contrast, many behaviorists view humans as being more passive in the developmental process.

Stability versus Change: How similar are you to how you were as a child? Were you always as out-going or reserved as you are now? Some theorists argue that the personality traits of adults are rooted in the behavioral and emotional tendencies of the infant and young child. Others disagree, and believe that these initial tendencies are modified by social and cultural forces over time.

Continuity versus Discontinuity: Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change? The answer to that question often depends on which developmental theorist you ask and what topic is being studied. The theories of Freud, Erikson, Piaget, and Kohlberg are called stage theories. Stage theories or discontinuous development assume that developmental change occurs in distinct stages that are qualitatively different from each other, and that unfold in a set, universal sequence . At each stage of development, children and adults have different qualities and characteristics. Thus, stage theorists assume development is discontinuous. Others, such as the behaviorists, Vygotsky, and information processing theorists, assume development is a more slow and gradual process known as continuous development . For instance, they would see the adult as not possessing new skills, but as using more advanced skills that were already present in some form in the child. Brain development and environmental experiences contribute to the acquisition of more developed skills.

Universal vs. context specific . A final assumption focuses on whether pathways of development are presumed to be (1) normative and universal, meaning that all people pass through them in the same sequence, or (2) differential and specific, meaning that a variety of different patterns and pathways of developmental change are possible depending on the individual and the context. Some theorists, like Piaget or Erickson, assume that everyone progresses through the same stages of cognitive development in the same order, or that everyone negotiates the same set of developmental tasks at about the same ages. Other theorists, who endorse lifespan or ecological systems approaches, believe that development can take on a wide variety of patterns and pathways, depending on the specific cultural, historical, and societal under which it unfolds.

What are the guiding meta-theories in human development?

These six basic assumptions are clustered into “packages” that go together. Clusters are organized around metaphors, which are at the root of meta-theories of humans and their development. We consider four meta-theories, each with its own metaphor: (1) humans as seeds , as depicted by Maturational meta-theories; (2) humans as machines , as depicted in Mechanistic meta-theories (3) humans as butterflies , as depicted in Organismic meta-theories; and (4) humans as participants in a tennis game, conversation, or dance , as depicted by Contextualist meta-theories. For an overview of these guiding meta-theories, see this chart [pdf] .

• Maturational meta-theory : Maturational meta-theories can be understood using the plant as a metaphor. It is as if humans develop the same way as plants. The important thing to study is people’s “seeds,” that is, their genetic make-up. People are assumed to be passive, the product of their genes. The environment can provide support and nutrition (rain, sun, and soil), but can’t change a person’s nature (poppy seeds will always produce poppies). The role of the person is to be reactive—to their genes. The course of development will be continuous or discontinuous depending on the genetic program, although acorns always grow into oak trees.
• Mechanistic meta-theory : Mechanistic meta-theories can be understood using the machine as a metaphor. It is as if humans change the same way as machines. People are assumed to be made up of pieces that can be studied apart from the rest of them. They are passive, with the energy coming from outside (like gasoline for a car). Development is continuous and people do not develop into something else (a car stays a car). The person can only react to the environment that is controlling them (like a car responding to the gas pedal or the brake). All causes for development come from the outside, from environmental forces.
• Organismic meta-theory : Organismic meta-theories can be understood using the butterfly as a metaphor. It is as if humans develop the same way as butterflies. People are assumed to be made up of structured wholes. Their nature is to be curious, interested, and open to growth. They are active and develop through discontinuous qualitatively different stages (like the caterpillar, chrysalis, and butterfly). People construct their own next steps in development based on the affordances and opportunities provided by the environment. Development is caused by imbalances that lead to structural reorganizations. Development is progressive (gets better) and only goes in one direction (from caterpillar toward butterfly) and not the reverse.
• Contextual meta-theory : Contextual meta-theories can be understood using the tennis game (or dance) as a metaphor. It is as if humans’ development is like a game of tennis or a dance. The important thing to study is the back and forth between the person and his or her context, both of which are assumed to be proactive and acting on their own agendas. Development can be continuous or discontinuous depending on how the game is played. Both person and environment are active partners in the system, which can lead to transformations in both.

What are examples of theories that fall within each meta-theory?

Nested within each higher-order meta-theory are sets of lower-level approaches or theories called “families” of perspectives or theories to denote that they share common properties, based on their similarity to the root metaphors and characteristics of the guiding meta-theories. This table contains several examples of “big” theories of development and provides an analysis of their defining features according to the meta-theoretical assumptions we have been discussing [pdf]. Based on this analysis, we indicate the higher-order family to which we think each big theory or approach belongs.

Although maturational meta-theories were prevalent in the beginning of the 20th century, their popularity has waxed and waned since then, and they have taken on many different forms. These include some formulations of behavioral genetics, sociobiology, evolutionary, ethological, neuroscience, temperament, and personality theories. Maturational assumptions are signaled by concepts such as “trait,” the search for “the aggression gene,” the discovery of the brain system, hormone, or neurotransmitter responsible for a specific condition, or any other terms that suggest development is solely the product of innate or immutable characteristics of individuals. Although they are not typically referred to as “maturational,” there are many kinds of theories that place all the active ingredients of behavior or development inside the head (or more specifically the social cognitions) of the person. Even if they are not direct descendants, these theories can be considered cousins of Maturational meta-theories because they are exclusively focused on the role of the individual.

The prototypic Mechanistic theories are behaviorist, operant, and classical conditioning learning theories, like social learning theory. This family of theories dominated psychology from the early to the mid-20th century, but Mechanistic theories are still alive and well in many areas, such as learning and motivation, and especially in many theories that have been adapted for use in educational systems. New kinds of machines serve as prototypes for mechanistic theories of memory, learning, and automatic functioning—focusing on the computer, the robot, and the automaton. Such assumptions have even pervaded our understanding of biological systems, as seen in metaphors like “the brain is a computer.” And although the “cognitive revolution” was supposed to have overthrown behaviorist assumptions, some cognitivistic theories treat humans as if they were information processing machines.

Perhaps surprisingly, there are also mechanistic assumptions embedded in certain progressive analyses of the effects of societal and social conditions, such as poverty, oppression, racism, and discrimination, which sometimes seem to imply that these external forces are the sole determinants of the development of stereotypes or implicit attitudes. In this case, because all people are presumed to passively internalize these societal prejudices, psychological phenomena are modeled after the metaphor of the “Xerox machine.” Just as in Maturational meta-theories, where humans could be seen as “hosts” to their genes, who were really running the show, in Mechanistic meta-theories, humans can be seen as “hosts” to their own behaviors, which are automatically reflexively produced based on previous social programming.

The prototypical Organismic theory is Piaget’s constructivist theory of cognitive and affective development, and the several neo-constructivist theories that were inspired by Piaget, for example, Kohlberg’s theory of the development of moral reasoning. Other theories living under the Organismic umbrella include Werner’s comparative psychology, focusing on the orthogenetic principle of differentiation and integration, and Erikson, who posited universal age-graded developmental tasks. Other theories that claim kinship with Organismic meta-theories (e.g., theories of intrinsic motivation) do not typically include notions of universal stages or tasks, but focus instead on Organismic assumptions about the nature of humans, specifically, that humans are innately active, curious, and interested, and inherently desire to explore, understand, and fit in with their social and physical environments. With the rise of radical contextualism and cultural relativism in psychology, theories of “universal” anything (e.g., psychological needs, stages, developmental tasks) have come increasingly under attack.

Some of the better-known members of the Contextualist family include Bronfenbrenner’s bio-ecological model and the lifespan approach, both of which arose in reaction to dominant meta-theories of their day (experimental child psychology and Piagetian psychology, respectively), with their almost exclusive focus on the child as a developing individual. The “contextualist” moniker reflects these perspectives’ insistence that development unfolds within and is shaped by higher-order multi-level ecological or contextual forces outside the individual, such as microsystem settings, and societal, cultural, and historical contexts.

Does the field of psychology have meta-theories?

During different historical periods, specific meta-theories dominated the field of psychology. For example, during the 1940s and 1950s, behaviorism held sway. In the 1960s, Piaget’s theories were introduced to the United States and captured the field’s attention. Some fierce theoretical and empirical battles were fought between behaviorists and Piagetians.

When a specific meta-theory governs the field, it becomes very difficult for researchers from opposing meta-theories to work—they have trouble getting funding, they have trouble getting their research findings published, and they are marginalized by other researchers. For example, when the area of motivation was dominated by behaviorists (who believed that all behavior was motivated by rewards and punishments), it was very difficult for researchers to study and publish research on intrinsic motivation.

What is the dominant meta-theory in the field today?

“Cognitivism” is a guiding meta-theory in the field of psychology today. “Cognitivism” is the assumption that all the causal factors that shape human behavior and development are inside the mind or belief system of the person. You can hear the assumptions in the theories of the field: self-efficacy, self-esteem, attributions, perceived social support, values, sense of purpose, goal orientations, internal working model, identity, and so on.

The paradigm that is currently taking over the field of psychology is neuroscience . That is, the brain is in charge of behavior, and neurobiology is destiny. Some branches of neuroscience are predominantly Maturational , as seen in discussions of the brain systems responsible for certain actions, predilections, and characteristics. Other branches are more Contextual , for example, research on neuroplasticity, which examines the way that social contexts and interactions shape the developing brain.

News flash : In the field of psychology outside developmental, most researchers assume that people don’t develop. In personality, social, cognitive, and industrial-organizational psychology, researchers largely examine individual differences as indicators of people’s permanent characteristics.

Who else has meta-theories?

Everyone has meta-theories about human nature and development: parents, teachers, nurses, social workers, doctors, business people, artists, politicians, and so on.

For example,

• doctors assume that weight loss is all about diet and exercise (nurture), so no one can do research on physiological differences in metabolism (nature).
• teachers have assumptions about whether students come with motivation (nature) or have to be motivated from the outside (nurture), and organize their classrooms accordingly.
• parents often argue about the nature of children’s development, whether it’s just the child’s personality (maturational), or the child is going through a normal stage (organismic), or if they are rewarding the wrong behavior (mechanistic).

What is the meta-theory that guides our class and this book?

Our class endorses a life-span perspective on human development, a contextualist perspective that fought its way through the dominant perspectives in child psychology (e.g., development ends at age 18), starting in the 1980s to become one of the dominant meta-theories governing the field of developmental science today. Note that your instructors chose your book, so their meta-theory is influencing the meta-theoretical filter through which you are learning about development.

What is the correct meta-theory?

There is no single correct definition of development or meta-theory. Really. Even the lifespan approach has its drawbacks.

However, as research accumulates, many theories derived from certain meta-theories have been found to be incomplete—so far researchers have not found any significant aspect of development that is caused only by nature or only by nurture. Therefore, most researchers currently say they favor interactionist metatheories, like contextualist or systems meta-theories. However, it is important to look carefully at researchers’ actual work, because sometimes they say that they have one meta-theory, but their work seems to be guided by assumptions from a different meta-theory.

Do I have a meta-theory about development?

Yes, you do. And you can figure out what it is. Although it’s not easy, you can discern your own assumptions about development—by thinking about which assumptions make the most sense to you. You can also see which kinds of theories you prefer and what kinds of recommendations you would make about how to structure development, like how people should parent, teach, or make policies. The hardest part about discovering your own meta-theory is realizing that it is made up of assumptions you have (based on your experiences and messages from society)—that aren’t necessarily true. Our meta-theories sure seem true to each of us!

How do I get rid of my meta-theory?

It’s not really possible to get rid of all of our assumptions. It is our goal to be aware of our own assumptions or meta-theories, to realize that they are not the truth but are our current working models of how the world operates and people develop. The most important thing is to be explicit about our assumptions and to be cognizant of how they are guiding our actions. It is a goal of this class to help students figure out their own assumptions and to help them become (or remain) open to alternative viewpoints.

Historical Theories of Development

Preformationist View : Well into the 18th century, children were merely thought of as little adults. Preformationism , or the belief that a tiny, fully formed human is implanted in the sperm or egg at conception and then grows in size until birth, was the predominant early theory. Children were believed to possess all their sensory capabilities, emotions, and mental aptitude at birth, and as they developed these abilities unfolded on a predetermined schedule (Thomas, 1979). The environment was thought to play no role in determining development .

John Locke (1632-1704): Locke, a British philosopher, refuted the idea of innate knowledge and instead proposed that children are largely shaped by their social environments, especially their education as adults teach them important knowledge. He believed that through education a child learns socialization, or what is needed to be an appropriate member of society. Locke advocated thinking of a child’s mind as a tabula rasa or blank slate , and whatever comes into the child’s mind comes from the environment. Locke emphasized that the environment is especially powerful in the child’s early life because he considered the mind the most pliable then. Locke indicated that the environment exerts its effects through associations between thoughts and feelings, behavioral repetition, imitation, and rewards and punishments (Crain, 2005). Locke’s ideas laid the groundwork for the behavioral perspective and subsequent learning theories of Pavlov, Skinner and Bandura.

Jean-Jacques Rousseau (1712-1778): Like Locke, Rousseau also believed that children were not just little adults. However, he did not believe they were blank slates, but instead developed according to a natural plan which unfolded in different stages (Crain, 2005). He did not believe in teaching them the correct way to think, but believed children should be allowed to think by themselves according to their own ways and an inner, biological timetable. This focus on biological maturation resulted in Rousseau being considered the father of developmental psychology. Followers of Rousseau’s developmental perspective include Gesell, Montessori, and Piaget.

Arnold Gesell (1880-1961): Gesell spent 50 years at the Yale Clinic of Child Development, and with his colleagues he studied the neuromotor development of children. Gesell believed that the child’s development was activated by genes and he called this process maturation (Crain, 2005). Further, he believed that development unfolded in fixed sequences, and he opposed efforts to teach children ahead of schedule as he believed they will engage in behaviors when their nervous systems had sufficiently matured.

Sigmund Freud (1856-1939): Freud was a very influential figure in the area of development. Freud emphasized the importance of early childhood experiences in shaping our personality and behavior. In our natural state, we are biological beings and are driven primarily by instincts. During childhood, however, we begin to become social beings as we learn how to manage our instincts and transform them into socially acceptable behaviors. His assumptions were that personality formed during the first few years of life. The ways in which parents or other caregivers interacted with children were assumed to have a long-lasting impact on children’s emotional states. His beliefs formed the psychodynamic perspective and his theories of psychosexual development and psychopathology dominated the field of psychiatry until the growth of behaviorism in the 1950s.

However, Freud’s theory has been heavily criticized for several reasons. One is that it is very difficult to test scientifically (Crews, 1998). Freud suggested that much of what determines our actions were unknown to us, and as scientists we cannot measure these unconscious concepts. A second criticism is that Freud’s case studies were not validated and cannot be used as evidence for his theories. Many later theories, particularly behaviorism and humanism, came about as challenges to Freud’s views.

Contemporary Theories on Development

Erikson (1902-1994) and Psychosocial Theory: Now, let’s turn to a less controversial psychodynamic theorist, Erik Erikson. Erikson presents eight developmental stages that encompass the entire lifespan. For that reason, Erikson’s psychosocial theory forms the foundation for much of our discussion of psychosocial development.

Erikson (1950) proposed a model of lifespan development that provides a useful guideline for thinking about the changes we experience throughout life. Erikson broke with Freud’s emphasis on sexuality as the cornerstone of social-emotional development and instead suggested that social relationships fostered development. Erikson proposed that each period of life has a unique challenge or crisis that the person who reaches it must face, referred to as psychosocial crises . According to Erikson, successful development involves dealing with and resolving the goals and demands of each of these psychosocial crises in a positive way. These crises are usually called stages, although that is not the term Erikson used. If a person does not resolve a stage successfully, it may hinder their ability to deal with later stages. For example, the person who does not develop a sense of trust (Erikson’s first stage) may find it challenging as an adult to form a positive intimate relationship (Erikson’s sixth stage). Or an individual who does not develop a clear sense of purpose and identity (Erikson’s fifth stage) may become self-absorbed and stagnate rather than work toward the betterment of others (Erikson’s seventh stage).

However, most individuals are able to successfully complete the eight stages of his theory (See Table 1.3).

Table 1.3 Erikson's Psychosocial Stages

Erikson’s theory has been criticized for focusing so heavily on crises and assuming that the completion of one crisis is a prerequisite for the next crisis of development. His theory also focused on the social expectations that are found in certain cultures, but not in all. For instance, the idea that adolescence is a time of searching for identity might translate well in the middle-class culture of the United States, but not as well in cultures where the transition into adulthood coincides with puberty through rites of passage and where adult roles offer fewer choices.

Learning Theory: Also known as Behaviorism , is based on the premise that it is not possible to objectively study the mind, and therefore psychologists should limit their attention to the study of behavior itself. The most famous behaviorist was Burrhus Frederick (B. F.) Skinner (1904–1990), who expanded the principles of behaviorism and also brought them to the attention of the public at large. Skinner used the ideas of stimulus and response, along with the application of rewards or reinforcements, to train pigeons and other animals. In addition, he used the general principles of behaviorism to develop theories about how best to teach children and how to create societies that were peaceful and productive (Skinner, 1957, 1968, 1972).

The behaviorists made substantial contributions to psychology by identifying the principles of learning. Although the behaviorists were incorrect in their beliefs that it was not possible to measure thoughts and feelings, their ideas provided new insights that helped further our understanding regarding the nature-nurture debate as well as the question of free will. The ideas of behaviorism are fundamental to psychology and have been developed to help us better understand the role of prior experiences in a variety of areas of psychology.

Social Learning Theory , or learning by watching others , was developed by Albert Bandura (1977). His theory calls our attention to the ways in which many of our actions are not learned through conditioning, as suggested by Skinner . Young children frequently learn behaviors through imitation. Especially when children do not know what else to do, they learn by modeling or copying the behavior of others.

Bandura (1986) suggests that there is interplay between the environment and the individual. We are not just the product of our surroundings, rather we influence our surroundings. There is interplay between our personality and the way we interpret events and how they influence us. This concept is called reciprocal determinism . An example of this might be the interplay between parents and children. Parents not only influence their child’s environment, perhaps intentionally through the use of reinforcement, etc., but children influence parents as well. Parents may respond differently with their first child than with their fourth. Perhaps they try to be the perfect parents with their firstborn, but by the time their last child comes along they have very different expectations, both of themselves and their child. Our environment creates us and we create our environment.

Other social influences: TV or not TV? Bandura, Ross and Ross (1963) began a series of studies to look at the impact of television on the behavior of children. Bandura began by conducting an experiment in which he showed children a film of a woman hitting an inflatable clown or “bobo” doll. Then the children were allowed in the room, where they found the doll and during their play they began to hit it. The children also demonstrated novel ways of being aggressive toward the doll that were not demonstrated by those children who did not see the aggressive model. Bandura’s research raised concerns about the impact of violence on young children. Since then, considerable research has been conducted on the impact of violent media on children’s aggression including playing video games.

Cognitive Theory: The cognitive theories focus on how our mental processes or cognitions change over time . Three important theories are Jean Piaget’s, Lev Vygotsky’s, and Information-processing.

Jean Piaget (1896-1980) was one of the most influential cognitive theorists in development. He was inspired to explore children’s ability to think and reason by watching his own children’s development. He was one of the first to recognize and map out the ways in which children’s intelligence differs from that of adults (Piaget, 1929). He became interested in this area when he was asked to test the IQ of children and began to notice that there was a pattern in their wrong answers. He believed that children’s intellectual skills change over time and that maturation, rather than training, brings about that change. Children of differing ages interpret the world differently. Piaget theorized that children progressed through four stages of cognitive development (see Table 1.4).

Table 1.4 Piaget's Stages of Cognitive Development

Piaget has been criticized for overemphasizing the role that physical maturation plays in cognitive development and in underestimating the role that culture and experience plays. Looking across cultures reveals considerable variation in what children are able to do at various ages. Research has shown considerable overlap among the four stages and that development is more continuous.

Lev Vygotsky (1896-1934) was a Russian psychologist who wrote in the early 1900s, but whose work was not discovered by researchers in the United States until the 1960s and became more widely known in the 1980s (Crain, 2005). His sociocultural theory emphasizes the importance of culture and interaction in the development of cognitive abilities . Vygotsky differed with Piaget in that he believed that a person not only has a set of abilities, but also a set of potential abilities that can be realized if given the proper guidance from others. Vygotsky developed theories on teaching that have been adopted by educators today.

Information Processing is not the work of a single theorist, but based on the ideas and research of several cognitive scientists studying how individuals perceive, analyze, manipulate, use, and remember information . This approach assumes that humans gradually improve in their processing skills; that is, cognitive development is continuous rather than stage-like. The more complex mental skills of adults are built from the primitive abilities of children. We are born with the ability to notice stimuli, store, and retrieve information. Brain maturation enables advancements in our information processing system. At the same time, interactions with the environment also aid in our development of more effective strategies for processing information.

Urie Bronfenbrenner (1917-2005) developed the Ecological Systems Theory , which provides a framework for understanding and studying the many influences on human development (Bronfenbrenner, 1979). Bronfenbrenner recognized that human interaction is influenced by larger social forces and that an understanding of these forces is essential for understanding an individual. The individual is impacted by several systems including:

• Microsystem includes the individual’s setting and those who have direct, significant contact with the person, such as parents or siblings . The input of those is modified by the cognitive and biological state of the individual as well. These influence the person’s actions, which in turn influence systems operating on him or her.
• Mesosystem includes the larger organizational structures, such as school, the family, or religion. These institutions impact the microsystems just described. The philosophy of the school system, daily routine, assessment methods, and other characteristics can affect the child’s self-image, growth, sense of accomplishment, and schedule thereby impacting the child, physically, cognitively, and emotionally.
• Exosystem includes the larger contexts of community . A community’s values, history, and economy can impact the organizational structures it houses. Mesosystems both influence and are influenced by the exosystem.
• Macrosystem includes the cultural elements, such as global economic conditions, war, technological trends, values, philosophies, and a society’s responses to the global community.
• Chronosystem is the historical context in which these experiences occur. This relates to the different generational time periods previously discussed, such as the baby boomers and millennials.

In sum, a child’s experiences are shaped by larger forces, such as the family, schools, religion, culture, and time period. Bronfenbrenner’s model helps us understand all of the different environments that impact each one of us simultaneously. Despite its comprehensiveness, Bronfenbrenner’s ecological system’s theory is not easy to use. Taking into consideration all the different influences makes it difficult to research and determine the impact of all the different variables (Dixon, 2003). Consequently, psychologists have not fully adopted this approach, although they recognize the importance of the ecology of the individual. Figure 1.9 is a model of Bronfenbrenner’s Ecological Systems Theory.

Human Development Essay: Topics, Examples, & How-to Guide

A human development essay is a piece of writing that explores how a person or group of people can grow and thrive. Several disciplines study these processes and might require you to get ready with this kind of assignment:

• Biology analyzes human body development issues throughout our lifespan;
• Psychology views human development as gaining or abandoning certain behavioral trends;
• Sociology explains the cause-and-effect relationships between an individual and a group;
• Economics studies the growth of human freedoms through the improvement of their well-being.

This article systematizes the available bulk of knowledge on the importance of human development. We have collected the essential concepts and approaches you can explore through our human development essay topics and samples.

• 2️⃣ HD & Economic Growth: Essay Example

The first Human Development Report introduced this notion back in 1990 . But the discussion of the relationship between economic growth and human development started in the middle of the 20 th century.

Now we believe that GDP is not the only indicator of our well-being . Human life is more than just selling, buying, and consuming.

Human development in economics focuses on the creation of equal rights and opportunities for everyone . This approach states that the entire society would prosper from the happiness of each of its members.

In these terms, human development has two dimensions:

• enhancement of human abilities;
• provision of prerequisites for our growth.

The former explores how we could ensure that everyone has access to education , healthcare, and decent living conditions. The latter involves achieving environmental sustainability and equality of rights and opportunities for people of all genders, ages, and ethnic backgrounds.

Human Development Index

The Human Development Index (HDI) emphasizes that people and their well-being are the criteria for a country’s prosperity, not only its economic growth.

Today, we use HDI to question the efficiency of national policy. It also allows us to compare different countries with the same GDP but different human development levels. Analyzing this data, governments can refocus their priorities and correct past mistakes.

HDI is calculated as the geometric mean of the following normalized indices:

• Life expectancy at birth is used to calculate the life expectancy index, where 85 years is the maximum.
• The education index is the sum of the expected and mean years of schooling divided by 2.
• This index is determined as GNI per capita.

Meanwhile, HDI is not as comprehensive as one might expect. HDRO (the Human Development Report Office) claims that it does not consider human inequalities, the empowerment of minorities, poverty levels, and gender disparity .

Psychology views human development from an individual’s perspective. This discipline distinguishes between three directions of human development.

• Physical changes occur in our bodies. How do we grow from a baby into an adult and from an adult into an older person? How do we acquire new motor skills, and what is the biology of our senses? What do our brains consist of , and how do they change with age? Correct answers to these questions help us explain the next direction.
• Cognitive changes cause the development of human behavior. What goes on in our brain that defines what kind of people we are? This domain focuses on logical thinking, learning, understanding, moral reasoning , and practical intelligence. It searches for the ways we could learn faster and become better versions of ourselves.
• Psychosocial changes track the growth of our social skills and preferences. It all starts with the principal caregiver. Gradually, we begin to interact with more people, such as friends, distant relatives, educators, and colleagues. It is all about our self-image, self-esteem , emotions, and relationships. The psychosocial domain also studies our ways to cope with losses or death.

Human Development Theories

The history of psychology knows many human development theories, many of which are still trusted. We will focus on the two fundamental approaches. They divide childhood into several critical stages that define our character, habits, likes, relationships, and even success in life.

Piaget’s 4 Stages of Cognitive Development

Piaget’s theory is the most widely accepted approach to child development. He believed that children construct knowledge while they manipulate and explore the objects around them. Jean Piaget marked four stages of cognitive development .

• Sensorimotor stage (0-2 years). A child learns that objects do not disappear. Their activity is all about experimenting with things to see what happens. This stage should culminate with developing the deferred imitation skill. It involves the ability to reproduce an action or sound made by another person later.
• Preoperational stage (2-6 years). Children use symbols to represent words and ideas. They develop the language and make-believe play but still lack logical reasoning . They are egocentric and cannot imagine that other people may feel or think differently.
• Concrete operational stage (6-12 years). Thinking becomes logical and focused. Children develop inductive reasoning: they observe to make generalizations about the world around them. But they still struggle with deductive thinking.
• Formal operational stage (12 years – adulthood). Abstract thinking emerges. They learn to develop theoretical ideas to explain the world.

Freud’s 5 Stages of Psychosexual Development

The Father of Psychoanalysis believed that human personality consisted of ego, superego, and id. They become unified and inseparable once the child passes the five stages of psychosexual development.

• Oral stage (0-1 year). The mouth is the pleasure center for the infant. That is why everyone is born with a sucking reflex. If the oral needs are not met during the first year of life, the child can start biting their nails or suck a thumb.
• Anal stage (1-3 years). Children gain control over their bodily functions. They experiment with feces. But early toilet training can make a child too obsessed with order.
• Phallic stage (3-6 years). Children find out the pleasure they can get from their genitals. According to Freud, this is when the sexual desire to the parent of the opposite sex emerges. Boys go through the Oedipus complex. They want to replace their father and see him as a rival in the mother’s love. Later, Carl Jung spoke of the Electra Complex, a similar mechanism in girls.
• Latency stage (6-12 years). Sexual instincts give way to the superego. During this period, children adopt the moral principles and values of their parents.
• Genital stage (12+ years). Sexual instincts reemerge. If all the above steps passed successfully, adolescents would show appropriate sexual behavior.

But this theory is too controversial to be taken for granted. Do parents define their child’s sexual and aggressive drives? Nobody knows for sure.

1️⃣ Human Development Essay Example #1 (Psychology)

Below you will find a sample of human development essays for a psychology-related discipline. It illustrates the outline we have mentioned above based on the topic Why Is Freud’s Developmental Theory considered outdated?

Human Development Theories Essay

1. Introduction. In the XXI century, we are all obsessed with development. We would like to become a better version of ourselves, develop our country, and humanity as a whole. Unfortunately, there is no axiom confirming the mechanism of human development.

Thesis statement. This essay explores the pitfalls of Freud’s developmental theory and questions its applicability.

2. Main Body.

Argument 1. Freud drew his theory from memories of his patients. But certain experiences people believe are true often turn out to be inaccurate. Sometimes, we fabricate our memories due to how we felt back then or would like to feel now. Thus, Freud used unreliable sources of information about child development.

Argument 2. Freud’s theory revolves around sexuality . But as Jung and Adler noticed, human life is more complicated than that. Oversimplification reduces us to instincts, which is not true. People have their subconscious fears and desires, but sexual energy is only one of their aspects.

Argument 3. Sigmund Freud only worked with adults. All adults are former children, but the researcher never studied children in their games, education, or frustrations. Freud had six kids, but his career never allowed him to spend much time with family. It is questionable how someone could draw conclusions about a child’s mental processes without actually speaking to a child.

3. Conclusion. Sigmund Freud largely contributed to modern psychology. He was the first to question our rational thinking and intellectual sobriety. But his five stages of psychosexual development are far from reality. First, they are constructed based on inaccurate and unreliable reports of mentally disturbed people. Second, sexuality is only one of the many things that make us who we are. Third, the scientist never did live research on children. That is why his theory is outdated now.

2️⃣ Human Development Essay Example #2 (Economics)

If you need to write an essay on human development while studying economics, you may use the following sample. It illustrates how to write an essay on the relationship between human development and economic growth.

Human Development and Economic Growth

1. Introduction. What happened first, human development or economic growth ? The early signs of economic growth appeared when the first people started exchanging their goods with the neighboring tribes. They had to develop a new skill and change their picture of the world to catalyze economic growth.

Thesis statement. This essay aims to confirm the two-way linkage between the development of individuals and economic growth.

Argument 1. If that first exchange of crops and cattle did not work out, we would have never got as developed as we are now. The economic growth that happened once we had mastered “business negotiations” gave us the necessary resources to develop other skills.

Argument 2. Human development is hardly predictable. The most significant improvements in technology, medicine, construction, and science happened during the most challenging times for humanity. The two world wars showed that we could develop when the economy is in decay. But the new production methods and scientific achievements give us an opportunity to grow the economy when things get better.

Argument 3. Economic growth without human development is limited. For example, when a third-world country receives an external capital inflow, its economy stabilizes or even grows. But if its population does not acquire new models of doing business, the money will end. Such a country will return to its previous poor condition.

3. Conclusion. It would be wrong to say that human development caused economic growth or vice versa. None of the two are possible without the other. Human development happened first, but further knowledge acquisition required economic growth. Improvement of the economy does not guarantee human intellectual growth. Meanwhile, it is an indispensable prerequisite for our development.

❓ Human Development Questions & Answers

What does the science of human development seek to understand.

This science tries to find the reasons why people tend to change over time or why they remain at the same level. It establishes the mechanisms through which we become more educated, moral, organized, and civilized. The science also describes the benefits and drawbacks of human development for the economy, sociology, psychology, and ecology.

What is Human Development and Family Studies?

Human Development and Family Studies focuses on the health and psychology of individuals throughout their lifespan. This area of knowledge discusses human life in the context of their family relationships and social roles. It is an interdisciplinary science that involves psychology, economy, and sociology.

How does culture affect human development?

Culture defines the way we perceive society and the world as a whole. It affects our vision of reality from early childhood. Culture influences our beliefs, values, and purposes. Moreover, it is a decisive factor for our self-image as an individual and a member of society.

What makes the study of human development a science?

The study of human development explores how we learn, mature, and adapt to changes and adverse conditions. It is largely related to psychology but also involves sociology, economics, anthropology, and biology. It is a science because it aims to describe, predict, and understand the changes in human behavior that bring us to development.

Module 1: Lifespan Development

Defining human development, learning outcomes.

• Describe human development and its three domains: physical, cognitive, and psychosocial development
• Explain key human development issues about the nature of change: continuous/discontinuous, one course/multiple courses, and nature/nurture

Domains in Human Development

Figure 1 . Human development encompasses the physical, cognitive, and psychosocial changes that occur throughout a lifetime.

Physical Domain

Many of us are familiar with the height and weight charts that pediatricians consult to estimate if babies, children, and teens are growing within normative ranges of physical development. We may also be aware of changes in children’s fine and gross motor skills, as well as their increasing coordination, particularly in terms of playing sports. But we may not realize that physical development also involves brain development, which not only enables childhood motor coordination but also greater coordination between emotions and planning in adulthood, as our brains are not done developing in infancy or childhood. Physical development also includes puberty, sexual health, fertility, menopause, changes in our senses, and primary versus secondary aging. Healthy habits with nutrition and exercise are also important at every age and stage across the lifespan.

Cognitive Domain

If we watch and listen to infants and toddlers, we can’t help but wonder how they learn so much so fast, particularly when it comes to language development. Then as we compare young children to those in middle childhood, there appear to be huge differences in their ability to think logically about the concrete world around them. Cognitive development includes mental processes, thinking, learning, and understanding, and it doesn’t stop in childhood. Adolescents develop the ability to think logically about the abstract world (and may like to debate matters with adults as they exercise their new cognitive skills!). Moral reasoning develops further, as does practical intelligence—wisdom may develop with experience over time. Memory abilities and different forms of intelligence tend to change with age. Brain development and the brain’s ability to change and compensate for losses is significant to cognitive functions across the lifespan, too.

Psychosocial Domain

Development in this domain involves what’s going on both psychologically and socially. Early on, the focus is on infants and caregivers, as temperament and attachment are significant. As the social world expands and the child grows psychologically, different types of play and interactions with other children and teachers become important. Psychosocial development involves emotions, personality, self-esteem, and relationships. Peers become more important for adolescents, who are exploring new roles and forming their own identities. Dating, romance, cohabitation, marriage, having children, and finding work or a career are all parts of the transition into adulthood. Psychosocial development continues across adulthood with similar (and some different) developmental issues of family, friends, parenting, romance, divorce, remarriage, blended families, caregiving for elders, becoming grandparents and great grandparents, retirement, new careers, coping with losses, and death and dying.

As you may have already noticed, physical, cognitive, and psychosocial development are often interrelated, as with the example of brain development. We will be examining human development in these three domains in detail throughout the modules in this course, as we learn about infancy/toddlerhood, early childhood, middle childhood, adolescence, young adulthood, middle adulthood, and late adulthood development, as well as death and dying.

Who Studies Human Development and Why?

Many academic disciplines contribute to the study of development and this type of course is offered in some schools as psychology (particularly as developmental psychology); in other schools, it is taught under sociology, human development, or family studies. This multidisciplinary course is made up of contributions from researchers in the areas of health care, anthropology, nutrition, child development, biology, gerontology, psychology, and sociology, among others. Consequently, the stories provided are rich and well-rounded and the theories and findings can be part of a collaborative effort to understand human lives.

The main goals of those involved in studying human development are to describe and explain changes. Throughout this course, we will describe observations during development, then examine how theories provide explanations for why these changes occur. For example, you may observe two-year-old children to be particularly temperamental, and researchers offer theories to explain why that is. We’ll learn a lot more about theories, especially developmental theories, in the next module.

Key Issues in Human Development

• Is the change smooth or uneven (continuous versus discontinuous)?
• Is this pattern of change the same for everyone, or are there different patterns of change (one course of development versus many courses)?
• How do genetics and environment interact to influence development (nature versus nurture)?

Is Development Continuous or Discontinuous?

Continuous development views development as a cumulative process, gradually improving on existing skills (Figure 2). With this type of development, there is a gradual change. Consider, for example, a child’s physical growth: adding inches to their height year by year. In contrast, theorists who view development as discontinuous believe that development takes place in unique stages and that it occurs at specific times or ages. With this type of development, the change is more sudden, such as an infant’s ability to demonstrate awareness of object permanence (which is a cognitive skill that develops toward the end of infancy, according to Piaget’s cognitive theory—more on that theory in the next module).

Figure 2 . The concept of continuous development can be visualized as a smooth slope of progression, whereas discontinuous development sees growth in more discrete stages.

Is There One Course of Development or Many?

Is development essentially the same, or universal, for all children (i.e., there is one course of development) or does development follow a different course for each child, depending on the child’s specific genetics and environment (i.e., there are many courses of development)? Do people across the world share more similarities or more differences in their development? How much do culture and genetics influence a child’s behavior?

Stage theories hold that the sequence of development is universal. For example, in cross-cultural studies of language development, children from around the world reach language milestones in a similar sequence (Gleitman & Newport, 1995). Infants in all cultures coo before they babble. They begin babbling at about the same age and utter their first word around 12 months old. Yet we live in diverse contexts that have a unique effect on each of us. For example, researchers once believed that motor development followed one course for all children regardless of culture. However, childcare practices vary by culture, and different practices have been found to accelerate or inhibit the achievement of developmental milestones such as sitting, crawling, and walking (Karasik, Adolph, Tamis-LeMonda, & Bornstein, 2010).

For instance, let’s look at the Aché society in Paraguay. They spend a significant amount of time foraging in forests. While foraging, Aché mothers carry their young children, rarely putting them down in order to protect them from getting hurt in the forest. Consequently, their children walk much later: They walk around 23–25 months old, in comparison to infants in Western cultures who begin to walk around 12 months old. However, as Aché children become older, they are allowed more freedom to move about, and by about age 9, their motor skills surpass those of U.S. children of the same age: Aché children are able to climb trees up to 25 feet tall and use machetes to chop their way through the forest (Kaplan & Dove, 1987). As you can see, our development is influenced by multiple contexts, so the timing of basic motor functions may vary across cultures. However, the functions are present in all societies.

How Do Nature and Nurture Influence Development?

Are we who we are because of nature (biology and genetics), or are we who we are because of nurture (our environment and culture)? This longstanding question is known in psychology as the nature versus nurture debate. It seeks to understand how our personalities and traits are the product of our genetic makeup and biological factors, and how they are shaped by our environment, including our parents, peers, and culture. For instance, why do biological children sometimes act like their parents—is it because of genetics or because of early childhood environment and what the child has learned from their parents? What about children who are adopted—are they more like their biological families or more like their adoptive families? And how can siblings from the same family be so different?

We are all born with specific genetic traits inherited from our parents, such as eye color, height, and certain personality traits. Beyond our basic genotype, however, there is a deep interaction between our genes and our environment. Our unique experiences in our environment influence whether and how particular traits are expressed, and at the same time, our genes influence how we interact with our environment (Diamond, 2009; Lobo, 2008). There is a reciprocal interaction between nature and nurture as they both shape who we become, but the debate continues as to the relative contributions of each.

• Eight Stages of Human Development?
• Theories of Human Development

Human Development vs. Developmental Psychology

What are the genetic factors that affect human growth and development, why do we study human growth and development.

Imagine two children born in the same town and the same year to families with similar socioeconomic statuses. One child grows up to be assertive and confident, while the other grows up to be timid and shy. The study of the stages of human development can help explain the reasons for these differences and much more.

What is human development, exactly? Human development is a branch of psychology with the goal of understanding people — how they develop, grow, and change throughout their lives. This discipline, which can help individuals better understand themselves and their relationships, is broad. As such, it can be used in various professional settings and career paths.

What Are the Eight Stages of Human Development?

If human development is the study of how people change throughout their lives, how and when does this development happen? Many scientists and psychologists have studied various aspects of human development, including ego psychologist Erik Erikson. He examined the impact of social experiences throughout an individual’s life and theorized that  psychosocial development happens in eight sequential parts . What are the eight stages of human development?

Stage 1 — Infancy: Trust vs. Mistrust

In the first stage of human development, infants learn to trust based on how well their caregivers meet their basic needs and respond when they cry. If an infant cries out to be fed, the parent can either meet this need by feeding and comforting the infant or not meet this need by ignoring the infant. When their needs are met, infants learn that relying on others is safe; when their needs go unmet, infants grow up to be less trusting.

Stage 2 — Toddlerhood: Autonomy vs. Shame and Doubt

In addition to autonomy versus shame and doubt, another way to think of the second stage is independence versus dependence. Like in the first stage, toddlers go through this stage responding to their caregivers. If caregivers encourage them to be independent and explore the world on their own, toddlers will grow up with a sense of self-efficacy. If the caregivers hover excessively or encourage dependence, these toddlers grow up with less confidence in their abilities.

For example, if a toddler wants to walk without assistance in a safe area, the caregiver should encourage this autonomy by allowing the independent behavior. If the caregiver insists on holding the toddler’s hand even when it’s not necessary, this attention can lead to doubt later in life.

Stage 3 — Preschool Years: Initiative vs. Guilt

During the preschool years, children learn to assert themselves and speak up when they need something. Some children may state that they’re sad because a friend stole their toy. If this assertiveness is greeted with a positive reaction, they learn that taking initiative is helpful behavior. However, if they’re made to feel guilty or ashamed for their assertiveness, they may grow up to be timid and less likely to take the lead.

Stage 4 — Early School Years: Industry vs. Inferiority

When children begin school, they start to compare themselves with peers. If children feel they’re accomplished in relation to peers, they develop strong self-esteem. If, however, they notice that other children have met milestones that they haven’t, they may struggle with self-esteem. For example, a first grader may notice a consistently worse performance on spelling tests when compared with peers. If this becomes a pattern, it can lead to feelings of inferiority.

The key components of Erikson’s model of human development include stage one, infancy, trust versus mistrust; stage two, toddlerhood, autonomy versus shame and doubt; stage three, preschool years, initiative versus guilt; stage four, early school years, industry versus inferiority; stage five, adolescence, identity versus role confusion; stage six, young adulthood, intimacy versus isolation; stage seven, middle adulthood, generativity versus stagnation; and stage eight, late adulthood, integrity versus despair.

Back To Top

Stage 5 — Adolescence: Identity vs. Role Confusion

The adolescent stage is where the term “identity crisis” originated, and for good reason. Adolescence is all about developing a sense of self. Adolescents who can clearly identify who they are grow up with stronger goals and self-knowledge than teenagers who struggle to break free of their parents’ or friends’ influences. Adolescents who still deeply depend on their parents for social interaction and guidance may experience more role confusion than teenagers who pursue their own interests.

Stage 6 — Young Adulthood: Intimacy vs. Isolation

In young adulthood, which begins roughly at age 20, people begin to solidify their lifelong bonds; many people enter committed relationships or marriages, while others form lifelong friendships. People who can create and maintain these relationships reap the emotional benefits, while those who struggle to maintain relationships may suffer from isolation. A young adult who develops strong friendships in college may feel more intimacy than one who struggles to form and maintain close friendships.

Stage 7 — Middle Adulthood: Generativity vs. Stagnation

In middle adulthood, people tend to struggle with their contributions to society. They may be busy raising children or pursuing careers. Those who feel that they’re contributing experience generativity, which is the sense of leaving a legacy. On the other hand, those who don’t feel that their work or lives matter may experience feelings of stagnation. For example, a middle-aged adult who’s raising a family and working in a career that presumably helps people may feel more fulfilled than an adult who’s working at a day job that feels meaningless.

Stage 8 — Late Adulthood: Integrity vs. Despair

As adults reach the end of life, they look back on their lives and reflect. Adults who feel fulfilled by their lives, either through a successful family or a meaningful career, reach ego integrity, in which they can face aging and dying with peace. If older adults don’t feel that they’ve lived a good life, they risk falling into despair.

Other Theories of Human Development

Although widely used, Erikson’s psychosocial development theory has been critiqued for focusing too much on childhood. Critics claim that his emphasis makes the model less representative of the growth that people experienced in adulthood. Erikson’s model of the stages of human development is only one theory addressing growth and change throughout life, as many other psychologists have researched their own  theories of human development , including the following:

Cognitive Development

Jean Piaget developed the theory of cognitive development. Piaget’s theory is widely used in education programs to prepare teachers to instruct students in developmentally appropriate ways. The theory is based on four stages:

• Sensorimotor —  In the sensorimotor stage (birth to 2 years old), children learn object permanence, which is the understanding that people and objects still exist even when they’re out of view.
• Preoperational —  In the preoperational stage (2-7 years old), children develop symbolic thought, which is when they begin to progress from concrete to abstract thinking. Children in this stage often have imaginary friends.
• Concrete operational —  In the concrete operational stage (7-11 years old), children solidify their abstract thinking and begin to understand cause and effect and logical implications of actions.
• Formal operational —  In the formal operational stage (adolescence to adulthood), humans plan for the future, think hypothetically, and assume adult responsibilities.

Moral Development

Lawrence Kohlberg created a theory of human development based on moral development concepts. The theory comprises the following stages:

• Preconventional —  In the preconventional stage, people follow rules because they’re afraid of punishment and make choices only with their best interests in mind.
• Conventional —  In the conventional stage, people act to avoid society’s judgment and follow rules to maintain the systems and structures that are already in place.
• Postconventional —  In the postconventional stage, a genuine concern for the welfare of others and the greater good of society guides people.

Psychosexual Theory

Sigmund Freud popularized the  psychosexual theory . The theory comprises five stages:

• Oral —  In the oral stage (birth to 1 year old), children learn to suck and swallow and may experience conflict with weaning.
• Anal —  In the anal stage (1-3 years old), children learn to withhold or expel feces and may experience conflict with potty training.
• Phallic —  In the phallic stage (3-6 years old), children discover that their genitals can give them pleasure.
•   Latency —  In the latency stage (roughly 6 years old through puberty), they take a break from these physical stages and instead develop mentally and emotionally.
• Genital —  In the genital stage (puberty through adulthood), people learn to express themselves sexually.

Ideally, children move through each phase fluidly as their sexual libidos develop, but if they’re stuck in any of the phases, they may develop a fixation that hinders their development.

Behavioral Theory

The behavioral theory focuses solely on a person’s behaviors rather than the feelings that go alongside those behaviors. It suggests that behaviors are conditioned in an environment due to certain stimuli. Behavioral theorists believe that behavior determines feelings, so changing behaviors is important because this will in turn change feelings.

The  attachment theory  focuses on the deep relationships between people across their lifetime. An important attachment theory finding is that children must develop at least one strong bond in childhood to trust and develop relationships as adults. The attachment theory comprises four stages:

• Asocial or  pre-attachment   (birth to 6 weeks old)
• Indiscriminate attachment (6 weeks old to 7 months old)
• Specific or discriminate attachment (7-9 months old)
• Multiple attachments (10 months old or later)

Social Learning Theory

The social learning theory builds upon the behavioral theory and postulates that people learn best by observing the behavior of others. They watch how others act, view the consequences, and then make decisions regarding their own behavior accordingly. The four stages in this theory are:

• Reproduction

In the attention stage, people first notice the behavior of others. In the retention stage, they remember the behavior and the resulting consequences. In the reproduction stage, people develop the ability to imitate the behaviors they want to reproduce, and in the motivation stage, they perform these behaviors.

Sociocultural Theory

The  sociocultural theory  ties human development to the society or culture in which people live. It focuses on the contributions that society as a whole makes to individual human development. For example, children who are raised to play outdoors develop differently from children who are raised to play indoors.

An important part of this theory is the zone of proximal development, which is an area of knowledge and skills slightly more advanced than a child’s current level. The zone of proximal development helps teachers think about and plan instruction, so sociocultural theory plays a large role in preservice teacher training.

What are the differences between human development and developmental psychology? These terms are closely related. In fact, the study of developmental psychology is most people’s entry into human development.

Developmental psychology  is defined as a scientific approach to explaining growth, change, and consistency throughout a lifetime. It uses various frameworks to understand how people develop and transform throughout their lives. The goals of developmental psychology are to describe, explain, and optimize development to improve people’s lives. In the real world, developmental psychology is used in the study of physical, psychological, emotional, social, personality, and perceptual development.

The  study of developmental psychology  can lead to careers in several different fields. Developmental psychologists often work in colleges and universities and focus on research and teaching. Others work in healthcare facilities, clinics, assisted living facilities, hospitals, mental health clinics, or homeless shelters. In these applied settings, their focus is more on assessing, evaluating, and treating people. According to June 2020 data from PayScale, developmental  psychologists earn an average annual salary of about $68,000 .

One more key element of human growth and development left to explore is  genetics . Genetics influences the speed and way in which people develop, though other factors, such as parenting, education, experiences, and socioeconomic factors, are also at play. The multiple genetic factors that affect human growth and development include genetic interactions and sex chromosome abnormalities.

Genetic Interactions

Genes can act in an additive way or sometimes conflict with one another. For example, a child with one tall parent and one short parent may end up between the two of them, at average height. Other times, genes follow a dominant-recessive pattern. If one parent has brown hair and the other has red hair, the red hair gene is the dominant gene if their child has red hair.

Gene-Environment Interactions

Humans’ genetic information is always interacting with the environment, and sometimes this can impact development and growth. For example, if a child in utero is exposed to drugs, the child’s cognitive abilities may be impacted, thus changing the developmental process. In addition, even if a child’s genes would indicate a tall height, if that child experiences poor nutrition as children, it may impact their height.

Sex Chromosome Abnormalities

Sex chromosome abnormalities impact as many as 1 in 500 births. The following syndromes are examples of sex chromosome abnormalities that can impact development:

• Klinefelter syndrome  is the presence of an extra X chromosome in males, which can cause physical characteristics such as decreased muscle mass and reduced body hair and may cause learning disabilities.
• Fragile X syndrome  is caused by a mutation in the FMR1 gene that makes the X chromosome  appear fragile . It can cause intellectual disability, developmental delays, or distinctive physical features such as a long face.
• Turner syndrome  happens when one of the X chromosomes is missing or partially missing. It only affects females and results in physical characteristics like short stature and webbed neck.

Down Syndrome

Down syndrome  is another common example of how genetics can impact development. This chromosomal disorder may cause some individuals to experience physical or intellectual development differences. Down syndrome occurs at the 21st chromosomal site, in which people with Down syndrome have three chromosomes rather than two.

Those with Down syndrome often have different physical characteristics and may be prone to physical problems like heart defects and hearing problems. Most individuals with Down syndrome have intellectual impairment, but the degree of this impairment varies from person to person.

The top reasons for studying human development are to gain an understanding of your own life experience, help others understand what they’re going through, understand the relationship of society and individual growth, lead more effectively, and support the physical and mental health of others.

The study of human growth and development offers a wealth of value for personal and professional growth and understanding. Many reasons exist for why we study human growth and development.

Common benefits include the following:

• To  gain a better understanding  of one’s own life experiences. This can help people personally reach an understanding of what childhood events shaped their adulthood.
• To  gain knowledge  of how social context impacts development. This knowledge can be invaluable for professionals like teachers as they gain a deeper understanding of their students.
• To  help others understand and contextualize  the ups and downs of life. This helps therapists and psychologists better aid their clients in self-discovery.
• To  understand how societal change can support growth  and development. This understanding helps decision-makers in schools change the educational culture for the better.
• To  become a more effective research, teacher, or leader  in many different industries. Understanding human development deeply and in context has many professional benefits that can lead to greater insight.
• To  support the physical and mental health of individuals  throughout their life span. Professionals like doctors, nurses, and therapists must understand human growth and development to better support their clients.

Students may choose to study human growth and development because of its array of applications across many professional fields. For example, students who want to become elementary school teachers may take courses on the stages of human development to understand cognitive development and how children’s brains grow and change.

Human development is a wide-reaching and ever-changing discipline. A knowledge of human development can be invaluable to people personally as they continue to learn and grow throughout their lives and professionally as they learn to apply what they’ve learned to their careers.

Developmental psychology is a scientific approach that aims to explain growth, change, and consistency though the lifespan. Developmental psychology examines how thinking, feeling, and behavior change throughout a person’s life.

A significant proportion of theories within this discipline focus on development during childhood, as this is the period during an individual’s lifespan when the most change occurs.

Developmental psychologists study a wide range of theoretical areas, such as biological, social, emotion, and cognitive processes.

Empirical research in this area tends to be dominated by psychologists from Western cultures such as North American and Europe, although during the 1980s Japanese researchers began making a valid contribution to the field.

• Maturation in psychology refers to the natural developmental process driven by genetics, leading to physical, behavioral, and psychological growth independent of learning or experience.
• The idiographic approach focuses on understanding unique, individual differences in experiences or behaviors, often using qualitative methods.
• Normative development in psychology refers to the typical sequence and timing of developmental milestones that most people experience within a population.

The three goals of developmental psychology are to describe, explain, and optimize development (Baltes, Reese, & Lipsitt, 1980).

Finally, developmental psychologists hope to optimize development, and apply their theories to help people in practical situations (e.g. help parents develop secure attachments with their children).

Continuity vs. Discontinuity in Human Development 

Think about how children become adults. Is there a predictable pattern they follow regarding thought and language and social development? Do children go through gradual changes or are they abrupt changes?

Normative development is typically viewed as a continual and cumulative process. The continuity view says that development is a smooth and gradual accumulation of abilities, with one stage flowing seamlessly into the next.

Children become more skillful in thinking, talking, or acting much the same way as they get taller.

It assumes that changes are incremental, with skills and knowledge building upon what was previously learned. The analogy often used to describe this perspective is viewing development as a slope or ramp, gradually inclining upwards.

The discontinuity view sees development as a more abrupt-a succession of changes that produce different behaviors in different age-specific life periods called stages. Biological changes provide the potential for these changes.

These stages are believed to be qualitatively different, each bringing a dramatic shift in abilities or behaviors.

Theorists like Jean Piaget and Erik Erikson support this perspective. They argue that children pass through distinct stages at certain ages, and the qualities of each stage are significantly different from those of other stages. This can be visualized as steps on a staircase.

We often hear people talking about children going through “stages” in life (i.e., “sensorimotor stage.”). These are called developmental stages-periods of life initiated by distinct transitions in physical or psychological functioning.

Psychologists of the discontinuity view believe that people go through the same stages, in the same order, but not necessarily at the same rate.

Stability vs. Change in Human Development

Stability implies personality traits present during infancy endure throughout the lifespan. It emphasizes the importance of early experiences on future development, suggesting that early childhood experiences play a significant role in determining adult personality traits and behaviors.

For example, a child who is cheerful and outgoing will likely grow into an adult with similar personality traits. Stability theorists believe that change is relatively difficult once initial personality traits have been established.

In contrast, change theorists argue that family interactions, school experiences, and acculturation modify personalities.

It implies that our behaviors, thoughts, and emotions are malleable and can be influenced by experiences and environments over time. This perspective suggests that it is equally likely for an introverted child to become an extroverted adult, depending on various factors such as life experiences, education, or trauma.

This capacity for change is called plasticity. For example, Rutter (1981) discovered that somber babies living in understaffed orphanages often become cheerful and affectionate when placed in socially stimulating adoptive homes.

Nature vs. Nurture

When trying to explain development, it is important to consider the relative contribution of both nature and nurture . Developmental psychology seeks to answer two big questions about heredity and environment:

• How much weight does each contribute?
• How do nature and nurture interact?

Nature refers to the process of biological maturation, inheritance, and maturation. One of the reasons why the development of human beings is so similar is because our common specifies heredity (DNA) guides all of us through many of the same developmental changes at about the same points in our lives.

Nurture refers to the impact of the environment, which involves the process of learning through experiences.

There are two effective ways to study nature-nurture.

• Twin studies: Identical twins have the same genotype, and fraternal twins have an average of 50% of their genes in common.
• Adoption studies: Similarities with the biological family support nature, while similarities with the adoptive family support nurture.

Historical Origins

Developmental psychology as a discipline did not exist until after the industrial revolution when the need for an educated workforce led to the social construction of childhood as a distinct stage in a person’s life.

The notion of childhood originates in the Western world and this is why the early research derives from this location. Initially, developmental psychologists were interested in studying the mind of the child so that education and learning could be more effective.

Developmental changes during adulthood are an even more recent area of study. This is mainly due to advances in medical science, enabling people to live to old age.

Charles Darwin is credited with conducting the first systematic study of developmental psychology. In 1877 he published a short paper detailing the development of innate forms of communication-based on scientific observations of his infant son, Doddy.

However, the emergence of developmental psychology as a specific discipline can be traced back to 1882 when Wilhelm Preyer (a German physiologist) published a book entitled The Mind of the Child .

In the book, Preyer describes the development of his own daughter from birth to two and a half years. Importantly, Preyer used rigorous scientific procedures throughout studying the many abilities of his daughter.

In 1888 Preyer’s publication was translated into English, by which time developmental psychology as a discipline was fully established with a further 47 empirical studies from Europe, North America and Britain also published to facilitate the dissemination of knowledge in the field.

During the 1900s three key figures have dominated the field with their extensive theories of human development, namely Jean Piaget (1896-1980), Lev Vygotsky (1896-1934) and John Bowlby (1907-1990). Indeed, much of the current research continues to be influenced by these three theorists.

• Human Development: Meaning, Objectives and Components

Let us make an in-depth study of the meaning, objectives and components of human development

Meaning of Human Development:

The term ‘human development’ may be defined as an expansion of human capabilities, a widening of choices, ‘an enhancement of freedom, and a fulfilment of human rights.

At the beginning, the notion of human development incorporates the need for income expansion. However, income growth should consider expansion of human capabilities. Hence development cannot be equated solely to income expansion.

Income is not the sum-total of human life. As income growth is essential, so are health, education, physical environment, and freedom. Human development should embrace human rights, socio-eco-politico freedoms. Based on the notion of human development. Human Development Index (HDI) is constructed. It serves as a more humane measure of development than a strictly .income-based benchmark of per capita GNP.

ADVERTISEMENTS:

The first UNDP Human Development Report published in 1990 stated that: “The basic objective of development is to create an enabling environ­ment for people to enjoy long, healthy and creative lives.” It also defined human development as “a process of enlarging people’s choices”, “and strengthen human capabilities” in a way which enables them to lead longer, healthier and fuller lives.

From this broad definition of human deve­lopment, one gets an idea of three critical issues involved in human development interpretation. These are: to lead a long and healthy life, to be educated, and to enjoy a decent standard of living. Barring these three crucial parameters of human development as a process enlarging people’s choices, there are additional choices that include political freedoms, other guaranteed human rights, and various ingredients of self-respect.

One may conclude unhesistantly that the absence of these essential choices debars or blocks many other opportunities that people should have in widening their choices. Human development is thus a process of widening people’s choices as well as raising the level of well-being achieved.

What emerges from- the above discussion is that economic growth measured in terms of per capita GNP focuses only on one choice that is income. On the other hand, the notion of human development embraces the widening of all human choices—whether economic, social, cultural or political. One may, however, contest GDP/GNP as a useful measure of development since income growth enables persons in expanding their range of choices.

This argument is, however, faulty. Most importantly, human choices go far beyond income expansion. There are so many choices that are not dependent on income. Thus, human development covers all aspects of development. Hence it is a holistic concept. “Economic growth, as such becomes only a subset of human development paradigm.”

Objectives of Human Development:

In the traditional development economics, development meant growth of per capita real income. Later on, a wider definition of develop­ment came to be assigned that focused on distributional objectives. Economic development, in other words, came to be redefined in terms of reduction or elimination of poverty and inequality.

These are, after all, ‘a goods-oriented’ view of development. True development has to be ‘people- centred’. When development is defined in terms of human welfare it means that people are put first. This ‘people-oriented’ view of development is to be called human development.

It is thus clear that per capita income does not stand as a true index of development of any country. To overcome this problem and to under­stand the dynamics of development, the United Nations Development Programme (UNDP) developed the concept of Human Development Index (HDI) in the 1990s. This index brought in revolutionary changes not only in development, but also in the policy environment in which the government was assigned a major role instead of market forces.

Economic development now refers to expan­ding capabilities. According to Amartya Sen, the basic objective of development is ‘the expansion of human capabilities’. The capability of a person reflects the various combinations of ‘doings and beings’ that one can achieve. It then reflects that the people are capable of doing or being. Capability thus describes a person’s freedom to choose between different ways of living.

For example:

Can people read and write? Are food­stuffs distributed among people in a universal manner? Do poor students get midday meal in schools? Do the poor children get adequately nourishing diets at home? No one would doubt that an illiterate poor person cannot have the same capabilities that a rich literate one gets. Thus capability failure leads to poverty and deprivation. This perspective of development, as enunciated by A. Sen, suggests why development economists put greater emphasis on education and health.

There are many countries in the world which —despite high levels of per capita GDP growth/ real income—experience high mortality rate, undernourishment rate, poor literacy, and so on. This is a case called ‘growth without development’. M. P Todaro and S. C. Smith assert: “Real in­come is essential, but to convert the characteristics of commodities into functions…. surely requires health and education as well as income.” In other words, income does not define peoples’ ‘well- being’ adequately.

Well-being, although a diverse notion, should consider health and education, in addition to income. Sen’s intellectual insights and fundamental ideas induced UNDP to formulate HDI as a comprehensive measure of development. It may be reiterated that the HDI as used in the Human Development Reports to compare different countries in the world has been designed as alternative to per capita GDP/GNP. Today, it is the most single commonly used measure to evaluate development outcomes.

Components of Human Development:

The noted Pakistani economist Mahbub ul Haq considered four essential pillars of human development.

i. Equality,

ii. Sustainability,

iii. Productivity, and

iv. Empowerment.

If development is viewed in terms of enhancing people’s basic capabilities, people must enjoy equitable access to opportunities. Such may be called equality-related capabilities. To ensure equality-related capabilities or access to opportunities what is essential is that the societal institutional structure needs to be more favourable or progressive.

In other words, the unfavourable initial asset distribution, like land, can be made more farmer-friendly through land reform and other redistributive measures. In addition, uneven income distribution may be addressed through various tax-expenditure policies. Economic or legislative- measures that interferes with market exchange may enable people to enlarge their capabilities and, hence, well-being.

Further, to ensure basic equality, political opportunities need to be more equal. In the absence of effective political organisation, disadvantaged groups are exploited by the ‘rich’ to further their own interests rather than social goals. However, participatory politics gets a beating by the inequality in opportunities in having basic education.

It is to be added here that basic education serves as a catalyst of social change. Once the access to such opportunity is opened up in an equitable way, women or religious minorities or ethnic minorities would be able to remove socio­economic obstacles of development. This then surely brings about a change in power relations and makes society more equitable.

Sustainability:

Another important facet of human development is that development should ‘keep going’, should ‘last long’. The concept of sustainable development focuses on the need to maintain the long term protective capacity of the biosphere. This then suggests that growth cannot go on indefinitely; there are, of course, ‘limits to growth.’

Here we assume that environment is an essential factor of production. In 1987, the Bruntland Commission Report (named after the then Prime Minister Go Harlem Bruntland of Norway) defined sustainable development as ‘… development that meets the needs of the present without compromising the ability of future generations to meet their basic needs.’ This means that the term sustainability focuses on the desired balance between future economic growth and environ-mental quality. To attain the goal of sustainable development, what is of great impor­tance is the attainment of the goal of both intra- generation and inter-generation equality.

This kind of inequality includes the term ‘social well-being’ not only for the present generation but also for the people who will be on the earth in the future. Any kind of environmental decline is tantamount to violation of distributive justice of the disadvan­taged peoples. Social well-being thus, then, depends on environ-mental equality.

Productivity:

Another component of human development is productivity which requires investment in people. This is commonly called investment in human capital. Investment in human capital—in addition to physical capital—can add more productivity.

The improvement in the quality of human resources raises the productivity of existing resources. Theodore W. Schultz—the Nobel Prize-winning economist—articulated its importance: “The decisive factors of production in improving the welfare of poor people are not space, energy, and crop land; the decisive factor is the improvement in population quality.” Empirical evidence from many East Asian countries corroborate this view.

Empowerment:

The empowerment of people—particularly women—is another com­ponent of human development. In other words, genuine human development requires empower­ment in all aspects of life. Empowerment implies a political democracy in which people themselves make the decisions about their lives. Under it, people enjoy greater political and civil liberties and remain free from excessive controls and regu­lations. Empowerment refers to decentralisation of power so that the benefits of governance are reaped by all peoples.

It focuses on grassroots participation which promotes democracy by enfranchising the disadvantaged groups. Unfortu­nately, benefits are cornered by the elites because of lack of empowerment of people. Participation as a goal is a feature of ‘bottom-up’ development strategy rather than ‘top-down’. Further, develop­ment policies and strategies male-dominated. But the benefits of development are to be made ‘gender-sensitive’.

Discrimination against women in health and education is very costly from the viewpoint of achieving development goals. Education of women can lead to a virtuous circle of lower fertility, better care of children, more educational oppor­tunity, and higher productivity. Above all, as women’s education rises, women’s independence in making their own choices also increase.

Anyway, decentralization and participation empower people, specially the women and the poor. It then breaks the ‘deprivation trap’. Mahbub ul Haq asserts: “If people can exercise their choices in the political, social and economic spheres, there is a good prospect that growth will be strong, democratic, participatory and durable.”

Development: essay on human development.

ADVERTISEMENTS:

This article provides information about the human and growth approach to development:

According to the United Nations Development Programme (UNDP), human development is a process of analysing people’s choices. In principle, these choices can be infinite and change over time. But at all levels of development, the three essential ones are there for people (a) to lead a long and healthy life, (b) to acquire knowledge and (c) to have access to resources needed for a decent standard of living.

Image Courtesy : assignmentpoint.com/wp-content/uploads/2012/02/Learning-Gets-Switched_-On11.jpg

If these essential choices are not available many other opportunities remain inaccessible. Human development, however, does not end there. Additional choices, ranging from political, economic and social freedom to opportunities for being creative and productive and enjoying personal self-respect and guaranteed human rights are also inseparable parts o human rights.

UNDP depicts two sides of human development: (a) the formation of human capabilities – such as improved health, knowledge and access to resources; and (b) the people making use of these capabilities for productive purposes – being active in cultural, social and political affairs.

If the scales of human development do not finely balance the two sides; considerable human frustration may result. According to this concept of human development, “income is merely one option that people would like to have, albeit an important one. But it is not the sum total of their lives. Development must, therefore, be more than just the expansion of income and wealth. Its focus must be people.”

The Human Development Approach to development is different from the conventional approaches development, i.e., the economic growth, human capital formation, human resources development, human welfare or the basic human needs approaches. Economic growth, that is, the increase in production (GDP) is necessary but not sufficient for human development.

The theories of human capital formation and human resources development consider the human being as a means and not as an end. They are concerned with the supply side. The human welfare approach visualises people only as passive recipients of benefits of development and not as its participants. The basic needs approach aims to satisfy the basic minimum needs, i.e., food, shelter, clothing, etc., the deprived sections of the population rather than on the issue of human choices.

The human development approach puts equal emphasis on the production and distribution of resources, expansion and use of human capabilities, scope of choice, livelihood security, participatory process, and social, economic and political freedom. All these indeed emphases a paradigm shift in the social development strategy of the State. The world has become more polarised and the wide gap between the poor and the rich has widened further.

The UNDP, in its Human Development Report, points that the poorest 20% of the world’s population has experienced a decline in its share of global income from 2.3% to 1.4% in the last 30 years, whereas the share of the richest 20% rose from 70% to 85% during the same period. The gap in per capita income between the industrial and developing world trebled. There have been regional imbalances. The UNDP has voiced its concern against the jobless, ruthless, voiceless, rootless and fortuneless growth in the late 1990s.

It was jobless growth, since the economy grew but did not expand the opportunities for employment for large sections of the population. For the developing countries, jobless growth has meant long hours and very low incomes for hundreds of millions of people in low productivity work in agriculture and in other informal sectors.

This developmental process has been rendered ruthless by the fact that the fruits of economic growth have mostly benefited the rich; while millions of people stagnate in poverty. Ruthless growth causes people’s cultural identity to wither. At places the dominant majority culture amplifies at the cost of marginalisation of the minority cultures.

It has also been a voiceless growth as in many places it has not ensured the process of democratic participation of the people in decision-making processes. The voiceless growth process also provides women a marginal role in economic development. Again, fast economic growth is also achieved in some countries at the cost of destruction of forests, polluting rivers, destroying bio-diversity and depleting natural resources.

In this futureless growth, the present generation squanders resources needed by the future generation. At times the futureless growth benefits the industrialised countries at the cost of increased pressure on the poor people of the developing countries. As against this backdrop, the UNDP says development that perpetuates today’s inequalities is neither sustainable nor worth sustaining.

It is important to examine how development is being viewed as freedom by Amartya Sen. According to him; development must be perceived as a vital process of expanding real freedom that people enjoy. As per him, expansion of real income and economic growth are not necessarily characteristics of successful development as countries with high GDP and per capita income at times have low achievements in the quality of life.

On the other hand, countries with low GDP and low per capita incomes have higher human development indicators. Here the central purpose of development is to improve human lives, i.e., expanding the range of things that human beings can achieve and can do. To him, the objective of development is to remove obstacles such as illiteracy, ill-health, poverty, lack of access to resources or lack of civil and political freedom.

He does not deny that economic prosperity should be the major goal of planning and policy making. This is, however, only an intermediate goal to contribute to the ultimate goal of development, i.e., the development of human lives. To Sen, both the primary end and the principal means of development is expansion of freedom as freedom in one type helps advancing freedom of other types.

While access to economic opportunities is a major factor of economic growth, he also recognizes the contribution of instrumental freedom (political freedom, economic facilities, social opportunities, transparency guarantees and protective security) in enhancing economic growth and the contribution of economic growth to facilitate those freedoms that come into the way of full attainment of human potentials.

The Lifespan Development Perspective Essay

Introduction, the lifespan perspective of development, conclusions, reference list.

Lifespan development is a progressive process of development in a human being involving an increase in age, which begins at conception and ends with death (Sugarman, 2000, p. 56). In addition, lifespan development can be divided into four levels depicting advanced functionality and character changes as an individual moves from one level to another.

These levels include childhood and adolescence; early adulthood; middle adulthood; and late adulthood (Sugarman, 2000, p. 56). This paper presents discussions on the lifespan perspective of development and two major theories of lifespan development. In addition, the impact of the interaction between genes and the environment on the process of human development is also discussed.

The lifespan perspective examines the changes that take place at each level of human development relative to the environmental (Society and culture) factors that influence these changes (Sigelman & Rider, 2008, p. 84). Moreover, the lifespan perspective can be defined in many ways.

For instance, the lifespan perspective can be a progressive and lifelong process of development that is not limited to any single level in human development. On the other hand, there are three major aspects of the lifespan perspective of development, which include the cognitive, social, physical dimensions of change (Sugarman, 2000, p. 59).

Furthermore, other studies claim that the perspective is plastic in nature because some domains of lifespan development increase while others decrease. This plasticity of the lifespan perspective occurs in response to various environmental factors that influence human development.

In addition, the perspective is embedded in the lifelong events that occur in the life of an individual. Thus, this perspective is studied by scientists, anthropologists, and psychologists, which brings out its multidisciplinary nature (Sugarman, 2000, p. 63). On the other hand, the perspective has different contextual implications. Therefore, human development is determined by biological, cultural, social, and physical environmental factors.

The three aspects of the lifespan perspective are also implicated in different developmental changes. The physical aspect of development involves changes in weight, height, shape, and the changes in individual experiences with the external environment (Sigelman & Rider, 2008, p. 86).

On the other hand, the social aspect of development involves changes in different phases of human development, which are directly influenced by the social environment such as social skills and relationships. Lastly, the cognitive domain of human development entails change in an individual’s thinking capacity, memory, and decision-making (Sugarman, 2000, p. 64).

The changes characterizing the lifespan perspective of development can also be divided into eight stages of human development. The first stage also known as the Trust vs. Mistrust stage occurs during the period between birth and one year.

Here, development of trust depends on the relationship between the toddler and the care-giver (Sugarman, 2000, p. 66). The second stage also known as Autonomy vs. Shame and Doubt period occurs during the early childhood stage. During this stage, the child is capable of making choices relative to the individualized willingness.

The Initiative vs. Guilt is the third stage in development, which occurs during the middle childhood stage. During this stage, children develop a sense of purpose through engaging in goal-oriented activities (Sigelman & Rider, 2008, p. 88). The fourth stage also called the Industry vs. Inferiority period occurs at the late childhood period. Here, children develop competence through learning social norms, basic education, and culture.

Additionally, the adolescence stage signifies the Identity vs. Role Confusion period. Here, individual values and choices develop because individuals are able to account for their actions. The Intimacy vs. Isolation period occurs during early adulthood and it is characterized by development of intimate relationships, marriage, and families (Sigelman & Rider, 2008, p. 90).

The Generativity vs. Stagnation period occurs during the middle adulthood stage. Here, individuals are committed with providing for their families and developing their careers. Lastly, the Integrity vs. Despair stage occurs during the late adulthood stage. The elderly individuals are self-contented and they are full of life experiences and advice.

Theories of Lifespan Development

There are many theories that attempt to explain the process of human development from different perspectives such as Freud’s theory of psychosexual development and Erikson’s theory on psychosocial development. Erikson’s theory posits that an individual encounters several conflicts during the development process, which depend on the type of relationship existing between this individual and the society.

Therefore, as an individual moves through the eight stages of development discussed above, he/she must solve the conflicts involved in one stage before moving to another. This ensures that one develops a sound personality; otherwise one may encounter difficulties in addressing conflicts in subsequent stages if the previous ones were not sufficiently resolved (Sugarman, 2000).

On the other hand, Freud’s theory states that the process of personality development occurs at the early childhood stage. Subsequently, the behavioral changes observed in developing individuals are influenced by the childhood events. Here, personality development occurs through several stages during the early childhood stage.

During this stage, the pleasure-oriented capabilities of an individual become focused on specific areas in one’s body. These capabilities also known as sexual libido or psychosexual energy play a major role in the subsequent behavioral changes in an individual (Sigelman & Rider, 2008).

Thus, if all the issues involved in the psychosexual stages of development are adequately resolved, then an individual develops a sound personality. However, if the psychosexual issues remain unresolved, the person involved is trapped in a particular stage until all the issues are resolved.

The Interaction of Genes and the Environment in Lifespan Development

A child inherits the genetic information of both parents through the information carriers known as genes. The genes are made up of DNA, which is found on chromosomes. On the other hand, the environment in the context of lifespan development refers to the total social and cultural factors surrounding a developing human being (Sigelman & Rider, 2008, p. 86). Therefore, lifespan development in children depends on two major factors; the genetic make-up of a child and the environmental factors.

However, the two factors can play a mutual role in influencing the development of different individuals in the society. Here, the epigenetic framework of development posits that the genetic make-up can be turned on and off relative to the internal and external environmental feedback (Sigelman & Rider, 2008, p. 89).

This gives the process of lifespan development the flexibility and plasticity described in the discussions above. For instance, the learning process in children follows a specific pattern of adaptability, which depends on the internal and external factors.

Therefore, during the early childhood stage, individuals use the environmental experiences in reasoning and acting. However, as the environmental factors and experiences change along the period of lifespan development, so does the emotional, reasoning, and social attributes in an individual (Sigelman & Rider, 2008, p. 91).

The paper presents discussions on the lifespan perspective of development, the theories of lifespan development and the interaction of heredity and environment to produce individual differences in development.

From the discussions above, the lifespan perspective of development examines the changes that occur in different individuals, which occur due to the interaction of the genetic make-up and the total circumstances surrounding an individual. On the other hand, this perspective is also reinforced by Freud’s theory of psychosexual development and Erikson’s theory of psychosocial development, which are summarized in the discussions above.
