What Are Nature vs. Nurture Examples?

How is nature defined, how is nurture defined, the nature vs. nurture debate, nature vs. nurture examples, what is empiricism (extreme nurture position), contemporary views of nature vs. nurture.

Nature vs. nurture is an age-old debate about whether genetics (nature) plays a bigger role in determining a person's characteristics than lived experience and environmental factors (nurture). The term "nature vs. nature" was coined by English naturalist Charles Darwin's younger half-cousin, anthropologist Francis Galton, around 1875.

In psychology, the extreme nature position (nativism) proposes that intelligence and personality traits are inherited and determined only by genetics.

On the opposite end of the spectrum, the extreme nurture position (empiricism) asserts that the mind is a blank slate at birth; external factors like education and upbringing determine who someone becomes in adulthood and how their mind works. Both of these extreme positions have shortcomings and are antiquated.

This article explores the difference between nature and nurture. It gives nature vs. nurture examples and explains why outdated views of nativism and empiricism don't jibe with contemporary views.

In the context of nature vs. nurture, "nature" refers to genetics and heritable factors that are passed down to children from their biological parents.

Genes and hereditary factors determine many aspects of someone’s physical appearance and other individual characteristics, such as a genetically inherited predisposition for certain personality traits.

Scientists estimate that 20% to 60% percent of temperament is determined by genetics and that many (possibly thousands) of common gene variations combine to influence individual characteristics of temperament.

However, the impact of gene-environment (or nature-nurture) interactions on someone's traits is interwoven. Environmental factors also play a role in temperament by influencing gene activity. For example, in children raised in an adverse environment (such as child abuse or violence), genes that increase the risk of impulsive temperamental characteristics may be activated (turned on).

Trying to measure "nature vs. nurture" scientifically is challenging. It's impossible to know precisely where the influence of genes and environment begin or end.

How Are Inherited Traits Measured?

“Heritability”   describes the influence that genes have on human characteristics and traits. It's measured on a scale of 0.0 to 1.0. Very strong heritable traits like someone's eye color are ranked a 1.0.

Traits that have nothing to do with genetics, like speaking with a regional accent ranks a zero. Most human characteristics score between a 0.30 and 0.60 on the heritability scale, which reflects a blend of genetics (nature) and environmental (nurture) factors.

Thousands of years ago, ancient Greek philosophers like Plato believed that "innate knowledge" is present in our minds at birth. Every parent knows that babies are born with innate characteristics. Anecdotally, it may seem like a kid's "Big 5" personality traits (agreeableness, conscientiousness, extraversion, neuroticism, and openness) were predetermined before birth.

What is the "Big 5" personality traits

The Big 5 personality traits is a theory that describes the five basic dimensions of personality. It was developed in 1949 by D. W. Fiske and later expanded upon by other researchers and is used as a framework to study people's behavior.

From a "nature" perspective, the fact that every child has innate traits at birth supports Plato's philosophical ideas about innatism. However, personality isn't set in stone. Environmental "nurture" factors can change someone's predominant personality traits over time. For example, exposure to the chemical lead during childhood may alter personality.

In 2014, a meta-analysis of genetic and environmental influences on personality development across the human lifespan found that people change with age. Personality traits are relatively stable during early childhood but often change dramatically during adolescence and young adulthood.

It's impossible to know exactly how much "nurture" changes personality as people get older. In 2019, a study of how stable personality traits are from age 16 to 66 found that people's Big 5 traits are both stable and malleable (able to be molded). During the 50-year span from high school to retirement, some traits like agreeableness and conscientiousness tend to increase, while others appear to be set in stone.

Nurture refers to all of the external or environmental factors that affect human development such as how someone is raised, socioeconomic status, early childhood experiences, education, and daily habits.

Although the word "nurture" may conjure up images of babies and young children being cared for by loving parents, environmental factors and life experiences have an impact on our psychological and physical well-being across the human life span. In adulthood, "nurturing" oneself by making healthy lifestyle choices can offset certain genetic predispositions.

For example, a May 2022 study found that people with a high genetic risk of developing the brain disorder Alzheimer's disease can lower their odds of developing dementia (a group of symptoms that affect memory, thinking, and social abilities enough to affect daily life) by adopting these seven healthy habits in midlife:

• Staying active
• Healthy eating
• Losing weight
• Not smoking
• Reducing blood sugar
• Controlling cholesterol
• Maintaining healthy blood pressure

The nature vs. nurture debate centers around whether individual differences in behavioral traits and personality are caused primarily by nature or nurture. Early philosophers believed the genetic traits passed from parents to their children influence individual differences and traits. Other well-known philosophers believed the mind begins as a blank slate and that everything we are is determined by our experiences.

While early theories favored one factor over the other, experts today recognize there is a complex interaction between genetics and the environment and that both nature and nurture play a critical role in shaping who we are.

Eye color and skin pigmentation are examples of "nature" because they are present at birth and determined by inherited genes. Developmental delays due to toxins (such as exposure to lead as a child or exposure to drugs in utero) are examples of "nurture" because the environment can negatively impact learning and intelligence.

In Child Development

The nature vs. nurture debate in child development is apparent when studying language development. Nature theorists believe genetics plays a significant role in language development and that children are born with an instinctive ability that allows them to both learn and produce language.

Nurture theorists would argue that language develops by listening and imitating adults and other children.

In addition, nurture theorists believe people learn by observing the behavior of others. For example, contemporary psychologist Albert Bandura's social learning theory suggests that aggression is learned through observation and imitation.

In Psychology

In psychology, the nature vs. nurture beliefs vary depending on the branch of psychology.

• Biopsychology:  Researchers analyze how the brain, neurotransmitters, and other aspects of our biology influence our behaviors, thoughts, and feelings. emphasizing the role of nature.
• Social psychology: Researchers study how external factors such as peer pressure and social media influence behaviors, emphasizing the importance of nurture.
• Behaviorism: This theory of learning is based on the idea that our actions are shaped by our interactions with our environment.

In Personality Development

Whether nature or nurture plays a bigger role in personality development depends on different personality development theories.

• Behavioral theories: Our personality is a result of the interactions we have with our environment, such as parenting styles, cultural influences, and life experiences.
• Biological theories: Personality is mostly inherited which is demonstrated by a study in the 1990s that concluded identical twins reared apart tend to have more similar personalities than fraternal twins.
• Psychodynamic theories: Personality development involves both genetic predispositions and environmental factors and their interaction is complex.

In Mental Illness

Both nature and nurture can contribute to mental illness development.

For example, at least five mental health disorders are associated with some type of genetic component ( autism ,  attention-deficit hyperactivity disorder (ADHD) ,  bipolar disorder , major depression, and  schizophrenia ).

Other explanations for mental illness are environmental, such as:

• Being exposed to drugs or alcohol in utero 
• Witnessing a traumatic event, leading to post-traumatic stress disorder (PTSD)
• Adverse life events and chronic stress during childhood

In Mental Health Therapy

Mental health treatment can involve both nature and nurture. For example, a therapist may explore life experiences that may have contributed to mental illness development (nurture) as well as family history of mental illness (nature).

At the same time, research indicates that a person's genetic makeup may impact how their body responds to antidepressants. Taking this into consideration is important for finding the right treatment for each individual.

 What Is Nativism (Extreme Nature Position)?

Innatism emphasizes nature's role in shaping our minds and personality traits before birth. Nativism takes this one step further and proposes that all of people's mental and physical characteristics are inherited and predetermined at birth.

In its extreme form, concepts of nativism gave way to the early 20th century's racially-biased eugenics movement. Thankfully, "selective breeding," which is the idea that only certain people should reproduce in order to create chosen characteristics in offspring, and eugenics, arranged breeding, lost momentum during World War II. At that time, the Nazis' ethnic cleansing (killing people based on their ethnic or religious associations) atrocities were exposed.

Philosopher John Locke's tabula rasa theory from 1689 directly opposes the idea that we are born with innate knowledge. "Tabula rasa" means "blank slate" and implies that our minds do not have innate knowledge at birth.

Locke was an empiricist who believed that all the knowledge we gain in life comes from sensory experiences (using their senses to understand the world), education, and day-to-day encounters after being born.

Today, looking at nature vs. nature in black-and-white terms is considered a misguided dichotomy (two-part system). There are so many shades of gray where nature and nurture overlap. It's impossible to tease out how inherited traits and learned behaviors shape someone's unique characteristics or influence how their mind works.

The influences of nature and nurture in psychology are impossible to unravel. For example, imagine someone growing up in a household with an alcoholic parent who has frequent rage attacks. If that child goes on to develop a substance use disorder and has trouble with emotion regulation in adulthood, it's impossible to know precisely how much genetics (nature) or adverse childhood experiences (nurture) affected that individual's personality traits or issues with alcoholism.

Epigenetics Blurs the Line Between Nature and Nurture

"Epigenetics " means "on top of" genetics. It refers to external factors and experiences that turn genes "on" or "off." Epigenetic mechanisms alter DNA's physical structure in utero (in the womb) and across the human lifespan.

Epigenetics blurs the line between nature and nurture because it says that even after birth, our genetic material isn't set in stone; environmental factors can modify genes during one's lifetime. For example, cannabis exposure during critical windows of development can increase someone's risk of neuropsychiatric disease via epigenetic mechanisms.

Nature vs. nurture is a framework used to examine how genetics (nature) and environmental factors (nurture) influence human development and personality traits.

However, nature vs. nurture isn't a black-and-white issue; there are many shades of gray where the influence of nature and nurture overlap. It's impossible to disentangle how nature and nurture overlap; they are inextricably intertwined. In most cases, nature and nurture combine to make us who we are.

The Nature vs. Nurture Debate

Genetic and Environmental Influences and How They Interact

• Definitions
• Interaction
• Contemporary Views

Nature refers to how genetics influence an individual's personality, whereas nurture refers to how their environment (including relationships and experiences) impacts their development. Whether nature or nurture plays a bigger role in personality and development is one of the oldest philosophical debates within the field of psychology .

Learn how each is defined, along with why the issue of nature vs. nurture continues to arise. We also share a few examples of when arguments on this topic typically occur, how the two factors interact with each other, and contemporary views that exist in the debate of nature vs. nurture as it stands today.

Nature and Nurture Defined

To better understand the nature vs. nurture argument, it helps to know what each of these terms means.

• Nature refers largely to our genetics . It includes the genes we are born with and other hereditary factors that can impact how our personality is formed and influence the way that we develop from childhood through adulthood.
• Nurture encompasses the environmental factors that impact who we are. This includes our early childhood experiences, the way we were raised , our social relationships, and the surrounding culture.

A few biologically determined characteristics include genetic diseases, eye color, hair color, and skin color. Other characteristics are tied to environmental influences, such as how a person behaves, which can be influenced by parenting styles and learned experiences.

For example, one child might learn through observation and reinforcement to say please and thank you. Another child might learn to behave aggressively by observing older children engage in violent behavior on the playground.

The Debate of Nature vs. Nurture

The nature vs. nurture debate centers on the contributions of genetics and environmental factors to human development. Some philosophers, such as Plato and Descartes, suggested that certain factors are inborn or occur naturally regardless of environmental influences.

Advocates of this point of view believe that all of our characteristics and behaviors are the result of evolution. They contend that genetic traits are handed down from parents to their children and influence the individual differences that make each person unique.

Other well-known thinkers, such as John Locke, believed in what is known as tabula rasa which suggests that the mind begins as a blank slate . According to this notion, everything that we are is determined by our experiences.

Behaviorism is a good example of a theory rooted in this belief as behaviorists feel that all actions and behaviors are the results of conditioning. Theorists such as John B. Watson believed that people could be trained to do and become anything, regardless of their genetic background.

People with extreme views are called nativists and empiricists. Nativists take the position that all or most behaviors and characteristics are the result of inheritance. Empiricists take the position that all or most behaviors and characteristics result from learning.

Examples of Nature vs. Nurture

One example of when the argument of nature vs. nurture arises is when a person achieves a high level of academic success . Did they do so because they are genetically predisposed to elevated levels of intelligence, or is their success a result of an enriched environment?

The argument of nature vs. nurture can also be made when it comes to why a person behaves in a certain way. If a man abuses his wife and kids, for instance, is it because he was born with violent tendencies, or is violence something he learned by observing others in his life when growing up?

Nature vs. Nurture in Psychology

Throughout the history of psychology , the debate of nature vs. nurture has continued to stir up controversy. Eugenics, for example, was a movement heavily influenced by the nativist approach.

Psychologist Francis Galton coined the terms 'nature versus nurture' and 'eugenics' and believed that intelligence resulted from genetics. Galton also felt that intelligent individuals should be encouraged to marry and have many children, while less intelligent individuals should be discouraged from reproducing.

The value placed on nature vs. nurture can even vary between the different branches of psychology , with some branches taking a more one-sided approach. In biopsychology , for example, researchers conduct studies exploring how neurotransmitters influence behavior, emphasizing the role of nature.

In social psychology , on the other hand, researchers might conduct studies looking at how external factors such as peer pressure and social media influence behaviors, stressing the importance of nurture. Behaviorism is another branch that focuses on the impact of the environment on behavior.

Nature vs. Nurture in Child Development

Some psychological theories of child development place more emphasis on nature and others focus more on nurture. An example of a nativist theory involving child development is Chomsky's concept of a language acquisition device (LAD). According to this theory, all children are born with an instinctive mental capacity that allows them to both learn and produce language.

An example of an empiricist child development theory is Albert Bandura's social learning theory . This theory says that people learn by observing the behavior of others. In his famous Bobo doll experiment , Bandura demonstrated that children could learn aggressive behaviors simply by observing another person acting aggressively.

Nature vs. Nurture in Personality Development

There is also some argument as to whether nature or nurture plays a bigger role in the development of one's personality. The answer to this question varies depending on which personality development theory you use.

According to behavioral theories, our personality is a result of the interactions we have with our environment, while biological theories suggest that personality is largely inherited. Then there are psychodynamic theories of personality that emphasize the impact of both.

Nature vs. Nurture in Mental Illness Development

One could argue that either nature or nurture contributes to mental health development. Some causes of mental illness fall on the nature side of the debate, including changes to or imbalances with chemicals in the brain. Genetics can also contribute to mental illness development, increasing one's risk of a certain disorder or disease.

Mental disorders with some type of genetic component include autism , attention-deficit hyperactivity disorder (ADHD), bipolar disorder , major depression , and schizophrenia .

Other explanations for mental illness are environmental. This includes being exposed to environmental toxins, such as drugs or alcohol, while still in utero. Certain life experiences can also influence mental illness development, such as witnessing a traumatic event, leading to the development of post-traumatic stress disorder (PTSD).

Nature vs. Nurture in Mental Health Therapy

Different types of mental health treatment can also rely more heavily on either nature or nurture in their treatment approach. One of the goals of many types of therapy is to uncover any life experiences that may have contributed to mental illness development (nurture).

However, genetics (nature) can play a role in treatment as well. For instance, research indicates that a person's genetic makeup can impact how their body responds to antidepressants. Taking this into consideration is important for getting that person the help they need.

Interaction Between Nature and Nurture

Which is stronger: nature or nurture? Many researchers consider the interaction between heredity and environment—nature with nurture as opposed to nature versus nurture—to be the most important influencing factor of all.

For example, perfect pitch is the ability to detect the pitch of a musical tone without any reference. Researchers have found that this ability tends to run in families and might be tied to a single gene. However, they've also discovered that possessing the gene is not enough as musical training during early childhood is needed for this inherited ability to manifest itself.

Height is another example of a trait influenced by an interaction between nature and nurture. A child might inherit the genes for height. However, if they grow up in a deprived environment where proper nourishment isn't received, they might never attain the height they could have had if they'd grown up in a healthier environment.

A newer field of study that aims to learn more about the interaction between genes and environment is epigenetics . Epigenetics seeks to explain how environment can impact the way in which genes are expressed.

Some characteristics are biologically determined, such as eye color, hair color, and skin color. Other things, like life expectancy and height, have a strong biological component but are also influenced by environmental factors and lifestyle.

Contemporary Views of Nature vs. Nurture

Most experts recognize that neither nature nor nurture is stronger than the other. Instead, both factors play a critical role in who we are and who we become. Not only that but nature and nurture interact with each other in important ways all throughout our lifespan.

As a result, many in this field are interested in seeing how genes modulate environmental influences and vice versa. At the same time, this debate of nature vs. nurture still rages on in some areas, such as in the origins of homosexuality and influences on intelligence .

While a few people take the extreme nativist or radical empiricist approach, the reality is that there is not a simple way to disentangle the multitude of forces that exist in personality and human development. Instead, these influences include genetic factors, environmental factors, and how each intermingles with the other.

Nature vs. Nurture

Reviewed by Psychology Today Staff

The expression “nature vs. nurture” describes the question of how much a person's characteristics are formed by either “nature” or “nurture.” “Nature” means innate biological factors (namely genetics ), while “nurture” can refer to upbringing or life experience more generally.

Traditionally, “nature vs. nurture” has been framed as a debate between those who argue for the dominance of one source of influence or the other, but contemporary experts acknowledge that both “nature” and “nurture” play a role in psychological development and interact in complex ways.

• The Meaning of Nature vs. Nurture
• The Nature-vs.-Nurture Debate
• Identifying Genetic and Environmental Factors

The wording of the phrase “nature vs. nurture” makes it seem as though human individuality— personality traits, intelligence , preferences, and other characteristics—must be based on either the genes people are born with or the environment in which they grew up. The reality, as scientists have shown, is more complicated, and both these and other factors can help account for the many ways in which individuals differ from each other.

The words “nature” and “nurture” themselves can be misleading. Today, “ genetics ” and “environment” are frequently used in their place—with one’s environment including a broader range of experiences than just the nurturing received from parents or caregivers. Further, nature and nurture (or genetics and environment) do not simply compete to influence a person, but often interact with each other; “nature and nurture” work together. Finally, individual differences do not entirely come down to a person’s genetic code or developmental environment—to some extent, they emerge due to messiness in the process of development as well.

A person’s biological nature can affect a person’s experience of the environment. For example, a person with a genetic disposition toward a particular trait, such as aggressiveness, may be more likely to have particular life experiences (including, perhaps, receiving negative reactions from parents or others). Or, a person who grows up with an inclination toward warmth and sociability may seek out and elicit more positive social responses from peers. These life experiences could, in turn, reinforce an individual’s initial tendencies. Nurture or life experience more generally may also modify the effects of nature—for example, by expanding or limiting the extent to which a naturally bright child receives encouragement, access to quality education , and opportunities for achievement.

Epigenetics—the science of modifications in how genes are expressed— illustrates the complex interplay between “nature” and “nurture.” An individual’s environment, including factors such as early-life adversity, may result in changes in the way that parts of a person’s genetic code are “read.” While these epigenetic changes do not override the important influence of genes in general, they do constitute additional ways in which that influence is filtered through “nurture” or the environment.

Theorists and researchers have long battled over whether individual traits and abilities are inborn or are instead forged by experiences after birth. The debate has had broad implications: The real or perceived sources of a person’s strengths and vulnerabilities matter for fields such as education, philosophy , psychiatry , and clinical psychology. Today’s consensus—that individual differences result from a combination of inherited and non-genetic factors—strikes a more nuanced middle path between nature- or nurture-focused extremes.

The debate about nature and nurture has roots that stretch back at least thousands of years, to Ancient Greek theorizing about the causes of personality. During the modern era, theories emphasizing the role of either learning and experience or biological nature have risen and fallen in prominence—with genetics gaining increasing acknowledgment as an important (though not exclusive) influence on individual differences in the later 20th century and beyond.

“Nature versus nurture” was used by English scientist Francis Galton. In 1874, he published the book English Men of Science: Their Nature and Nurture , arguing that inherited factors were responsible for intelligence and other characteristics.

Genetic determinism emphasizes the importance of an individual’s nature in development. It is the view that genetics is largely or totally responsible for an individual’s psychological characteristics and behavior. The term “biological determinism” is often used synonymously.

The blank slate (or “tabula rasa”) view of the mind emphasizes the importance of nurture and the environment. Notably described by English philosopher John Locke in the 1600s, it proposed that individuals are born with a mind like an unmarked chalkboard and that its contents are based on experience and learning. In the 20th century, major branches of psychology proposed a primary role for nurture and experience , rather than nature, in development, including Freudian psychoanalysis and behaviorism.

Modern scientific methods have allowed researchers to advance further in understanding the complex relationships between genetics, life experience, and psychological characteristics, including mental health conditions and personality traits. Overall, the findings of contemporary studies underscore that with some exceptions—such as rare diseases caused by mutations in a single gene—no one factor, genetic or environmental, solely determines how a characteristic develops.

Scientists use multiple approaches to estimate how important genetics are for any given trait, but one of the most influential is the twin study. While identical (or monozygotic) twins share the same genetic code, fraternal (or dizygotic) twins share about 50 percent of the same genes, like typical siblings. Scientists are able to estimate the degree to which the variation in a particular trait, like extraversion , is explained by genetics in part by analyzing how similar identical twins are on that trait, compared to fraternal twins. ( These studies do have limitations, and estimates based on one population may not closely reflect all other populations.) 

It’s hard to call either “nature” or “nurture,” genes or the environment, more important to human psychology. The impact of one set of factors or the other depends on the characteristic, with some being more strongly related to one’s genes —for instance, autism appears to be more heritable than depression . But in general, psychological traits are shaped by a balance of interacting genetic and non-genetic influences.

Both genes and environmental factors can contribute to a person developing mental illness. Research finds that a major part of the variation in the risk for psychiatric conditions such as autism spectrum disorder, anxiety disorders, depression, and schizophrenia can be attributed to genetic differences. But not all of that risk is genetic, and life experiences, such as early-life abuse or neglect, may also affect risk of mental illness (and some individuals, based on their genetics, are likely more susceptible to environmental effects than others).

Like other psychological characteristics, personality is partly heritable. Research suggests less than half of the difference between people on measures of personality traits can be attributed to genes (one recent overall estimate is 40 percent). Non-genetic factors appear to be responsible for an equal or greater portion of personality differences between individuals. Some theorize that the social roles people adopt and invest in as they mature are among the more important non-genetic factors in personality development.

A Personal Perspective: Facing the interplay between genetic factors and linguistic development prompted a question: Should I trust my instincts or those of others?

The latest findings on genetics reveals how genes may affect the risk for substance use disorders, and how they can help predict which treatment will work.

How do we make sense of new experiences? Ultimately, it's about how we categorize them—which we often do by "lumping" or "splitting" them.

How are twin studies used to answer questions related to the nature-and-nurture debate?

The question of whether it is genes or environment that largely shapes human behaviour has been debated for centuries. During the second half of the 20th century, there were two camps of scientists – each believing that nature or nurture, respectively, was exclusively at play.

This view is becoming increasingly rare, as research is demonstrating that genes and environment are actually interconnected and can amplify one another. During an event at Berlin Science Week on November 7, organised by the Royal Society , we discussed how the debate is changing as a result of recent findings.

Take literacy. Making language visible is one of the most extraordinary achievements of human beings. Reading and writing is fundamental to our ability to thrive in the modern world, yet some individuals find it difficult to learn. This difficulty can arise for many reasons, including dyslexia, a neuro-developmental disorder. But it turns out neither genes nor environment are fully responsible for differences in reading ability.

Genetics and the neuroscience of reading

Reading is a cultural invention and not a skill or function that was ever subject to natural selection. Written alphabets originated around the Mediterranean about 3,000 years ago, but literacy only became widespread from the 20th century. Our use of the alphabet, however, is grounded in nature. Literacy hijacks evolved brain circuitry to link visible language to audible language – by letter-sound mapping.

Brain scans show that this “reading network” is apparent in pretty much the same place in the brain in everybody. It forms when we learn to read and strengthens connections between our brain’s language and speech regions, as well as a region that has become known as the “visual word form area”.

The design for building the underlying circuitry is somehow encoded in our genomes. That is, the human genome encodes a set of developmental rules that, when played out, will give rise to the network.

However, there is always variation in the genome and this leads to variation in the way these circuits develop and function. This means there are individual differences in ability. Indeed, variation in reading ability is substantially heritable across the general population, and developmental dyslexia is also largely genetic in origin .

This is not to say that there are “genes for reading”. Instead, there are genetic variations that affect how the brain develops in ways that influence how it functions. For unknown reasons, some such variants negatively affect the circuits required for speaking and reading.

Environment matters too

But genes are not the whole story. Let’s not forget that experience and active instruction are needed for the changes in brain connectivity that enable reading to occur in the first place – though we don’t yet know to what extent.

Research has shown that most often problems with literacy are likely underpinned by a difficulty in phonology – the ability to segment and manipulate the sounds of speech. It turns out that people with dyslexia also tend to struggle with learning how to speak when infants. Experiments have shown that they are slower than other people to name objects. This also applies to written symbols and relating them to speech sounds.

And here nurture comes in again. Difficulties in learning to read and write are particularly visible in languages with complex grammar and spelling rules, such as English. But they are far less obvious in languages with more straightforward spelling systems, such as Italian. Tests of phonology and object naming, however, can detect dyslexia in Italian speakers too.

So the difference that is found in dyslexic brains is likely the same everywhere, but will nevertheless play out very differently in different writing systems.

Amplification and cycles

Nature and nurture are traditionally set in opposition to each other. But in truth, the effects of environment and experience often tend to amplify our innate predispositions . The reason is that those innate predispositions affect how we subjectively experience and respond to various events, and also how we choose our experiences and environments. For example, if you are naturally good at something you are more likely to want to practice it.

This dynamic is especially evident for reading. Children with greater reading ability are more likely to want to read . This will of course further increase their reading skills, making the experience more rewarding. For children with lower natural reading ability, the opposite tends to happen – they will choose to read less, and will fall farther behind their peers over time.

These cycles also offer a window of intervention. As we have seen in the case of Italian readers, nurture can mitigate the effects of an adverse genetic predisposition. Similarly, a good teacher who knows how to make practice rewarding can help poor readers by allowing short cuts and mnemonics for spelling. In this way, dyslexic readers can become good readers – and enjoy it. Reward and practice enhance each other, leading to more motivation and more practice in a positive feedback loop.

So instead of thinking of nature and nurture as adversaries in a zero sum game, we should think of them as feedback loops where a positive influence of one factor increases the positive influence of the other – producing not a sum but an enhancement. Of course, the same applies to negative feedback, and so we have both virtuous and vicious circles.

Because inheritance (genetic as well as cultural) matters, this effect is also visible on a larger scale spanning several generations. In the past, parents who sent their children to school created an advantageous environment for them and their grandchildren. But in turn, the parents benefited from the existence of a culture that invested in schools. Of course, such investments are not always spread evenly and may flow more towards those already in an advantageous position. Such a circle is sometimes referred to as the “Matthew effect” – good things come to those who already have them.

The interactive loops between nature and nurture extend beyond the lives of individuals, playing out across communities and over generations. Recognising these dynamics gives us some power to break these feedback loops, both in our own lives and more widely in society and culture.

Nature versus Nurture Debate in Psychology by Hunter Honeycutt LAST REVIEWED: 12 January 2023 LAST MODIFIED: 12 January 2023 DOI: 10.1093/obo/9780199828340-0305

The nature-nurture dichotomy is a long-standing and pervasive framework for thinking about the causal influences believed to be operating during individual development. In this dichotomy, nature refers to factors (e.g., genes, genetic programs, and/or biological blueprints) or forces (e.g., heredity and/or maturation) inherent to the individual that predetermine the development of form and function. Nurture generally refers to all the remaining, typically “external,” causal factors (e.g., physical and social conditions) and processes (e.g., learning and experience) that influence development. The nature versus nurture debate in psychology deals with disagreements about the extent to which the development of traits in humans and animals reflects the relative influence of nature and nurture. It is commonly stated that psychologists have moved on from asking whether traits (or variation in traits) develop from nature or nurture, to recognize instead that both nature and nurture work together or “interact” to produce outcomes, although exactly how to view the interaction is a matter of much debate. While acknowledging the interaction of nature and nurture, one’s theoretical models and research focus might emphasize the prominence of one over the other. Thus, nativists focus more on the importance of innate factors or forces operating on development, whereas empiricists focus more on experiential or environmental factors. However, not everyone finds value in thinking about development in terms of nature and nurture. By the middle of the twentieth century, some psychologists, biologists, and philosophers began to view nature-nurture as a conceptually deficient and biologically implausible dichotomy that oversimplifies the dynamics of behavior and development. Such people espouse some variant of “developmental systems theory” and seek to eliminate or otherwise fuse the nature-nurture division.

The works in this section are mostly trade books that provide general introductions to the nature-nurture debate across a variety of topical areas in psychology, all of which would be suitable for use in classes with undergraduate students at all levels. Goldhaber 2012 contrasts four popular perspectives on the nature-nurture issue and would be a good place to start for anyone unfamiliar with the nature-nurture debate in psychology. Nativist perspectives are represented by Pinker 2002 , Plomin 2018 , and Vallortigara 2021 . An empiricist-leaning position on behavior development is put forth in Schneider 2012 . Developmental systems theory is promoted in Blumberg 2005 and Moore 2002 . Two edited books are included and both are better suited for advanced undergraduate- or graduate-level students. The first edited book, Coll, et al. 2013 , focuses on the nature-nurture issue across a range of topics and perspectives in psychology. The other, Mayes and Lewis 2012 , presents empiricist (or environmentalist) perspectives on child development.

Bateson, P. 2017. Behaviour, development and evolution . Cambridge, UK: OpenBook Publishers.

DOI: 10.11647/OBP.0097

Written by a distinguished ethologist who draws extensively from his work on animal behavior, this book argues that the nature-nurture division is neither valid nor helpful in capturing the complex system of factors that influence behavioral development. Topics include imprinting and attachment, parent-offspring relations, the influence of early-life experiences on later-life outcomes, problems with genetic determinism, and the role of behavior in evolutionary change.

Blumberg, M. S. 2005. Basic instinct: The genesis of novel behavior . New York: Thunder’s Mouth Press.

Consistent with developmental systems theory, Blumberg presents an overview of the conceptual and empirical limitations of nativism in explanations of behavioral and neural development in animals and cognitive development in humans.

Coll, C. G., E. L. Bearer, and R. M. Lerner, eds. 2013. Nature-nurture: The complex interplay of genetic and environmental influences on human behavior and development . New York: Psychology Press.

The contents of this edited volume are almost entirely original works with commentary that span multiple disciplines (psychology, biology, economics, philosophy) and multiple perspectives (behavioral genetics and developmental systems theory) on the nature-nurture issue.

Goldhaber, D. 2012. The nature-nurture debates: Bridging the gap . Cambridge, UK: Cambridge Univ. Press.

DOI: 10.1017/CBO9781139022583

Goldhaber reviews four major perspectives (behavior genetics, environmentalism, evolutionary psychology, and developmental systems theory) on the nature-nurture issue. He argues we should reject reductionist views based on either genetic determinism or environmental determinism in favor of more holistic, interactionist approaches.

Mayes, L. C., and M. Lewis, eds. 2012. The Cambridge handbook of environment in human development . Cambridge, UK: Cambridge Univ. Press.

This handbook explores a wide variety of ways in which the environment influences child development. Chapters cover conceptual frameworks and methodological issues in thinking about and studying environmental influences as well reviewing ways in which environmental contexts and systems influence specific aspects of child development.

Moore, D. S. 2002. The dependent gene: The fallacy of nature vs. nurture . New York: Henry Holt.

This book provides an introduction to the developmental systems theory take on the nature-nurture issue particularly as it relates to genetic determinism, heritability and heredity.

Pinker, S. 2002. The blank slate: The modern denial of human nature . New York: Viking.

In this best-selling book, Pinker draws on evidence from behavioral genetics, evolutionary psychology, and cognitive psychology to argue for a nativist position concerning human nature.

Plomin, R. 2018. Blueprint: How DNA makes us who we are . Cambridge, MA: MIT Press.

Plomin reviews traditional and more modern evidence from behavioral genetics to argue that genes are the primary factor in bringing about psychological differences between people. Moreover, he argues that many “environmental” factors operating on development are themselves strongly influenced by genetic differences.

Schneider, S. M. 2012. The science of consequences: How they affect genes, change the brain, and impact our world . Amherst, NY: Prometheus Books.

Schneider presents a view grounded in behavior analysis to argue for the critical role that the consequences of genetic activity, neural activity, and behavioral activity play in individual development. While emphasizing environmental (or experiential) factors influencing development, this book also highlights the systemic and interactive nature of developmental systems across multiple levels of analysis.

Vallortigara, G. 2021. Born knowing: Imprinting and the origins of knowledge . Cambridge, MA: MIT Press.

DOI: 10.7551/mitpress/14091.001.0001

Drawing upon research in comparative cognition and comparative neuroscience, much of it his own, Vallortigara argues that animals, including humans, enter the world with a set of unlearned, innate or instinctive behaviors and neural circuits that bias or predispose subsequent learning and development.

Nature Vs Nurture Essay for Students and Children

500+ words essay on nature vs nurture.

The topic of nature vs nurture is always a great topic of debate among people. There are great men who did work hard to achieve great heights . But still, they are some people who didn’t work that hard yet still managed to be successful.

In other words, it is a debate between hard work and talent. In the grooming of a person, the nurturing is essential. However, still, there are some individuals who were never born in a great environment . Yet by their sense of knowledge and intellectualism created a special place in the hearts of people.

Nature has given us many things in life and one of them is talents. Either we are born as the only individual in our family or it is in our genes. Furthermore, nature plays a vital role in deciding the future of a child. Many singers in this era are born with beautiful voices. They did not need any nurturing. Their talent took them to heights they couldn’t even imagine.

For instance, some of the great legends like Lata Mangeshkar, Asha Bhosle, Kishor Kumar had soulful voices. Also, they were the ones who sang from their childhood days. They started their careers and became successful at a very early age. Moreover, they did not get much teaching but still are the legends of all time.

Apart from singing, there are other talents that nature has given us. Various scientists like Albert Einstein , Isaac Newton , Galileo Galilei, started their work in their teenage years. They had amazing intellectualism, because of which they got recognition in their entire world. Furthermore, these scientists did not get any mentoring. They did everything on their own. Because they had extraordinary intelligence and ambition in life.

On the other hand, the nurturing of a person is important. Because hard work beats talent. With proper mentoring and practice, a person can achieve success in life. If a person has an environment in which everybody is in the same profession and are successful in it.

Then there is a great chance that the person will land up in the same profession and will achieve heights. Because in that environment he will get proper nurturing.

Furthermore, he will also be able to perform better over the years. “ Hard work always pays off ”. This idiom is always true and nobody can deny that. If a person has true dedication then it can beat talent. Various singers, dancers, musicians, businessmen, entrepreneurs did work really hard for years.

And because of that, they got recognition in the entire world. In these categories, musicians are who achieved heights only with their hard work and constant practice.

It is true that there are no shortcuts to success. Various known legends like Bob Dylon. Lou Reed, Elvis Persley, Michael Jackson worked hard throughout their lives. As a result, they were some of the great personalities in the entire world.

Q1. What is the meaning of nurture?

A1. Nurture means the way a person grooms himself. This is done in order to achieve success. Nurturing is essential in a person’s life because it can be a way a person can cross the barrier and do something great. Moreover nurture also means the mentoring and care a person is getting in an environment.

Q2. What is the difference between Nature and Nurture?

A2. The main difference between nature and nurture is, nature is the talent a person inherits from his parents or is God gifted. While nurturing is hard work and mentoring of a person in a particular field. So that he may excel in that field.

Grand Challenge: Nature Versus Nurture: How Does the Interplay of Biology and Experience Shape Our Brains and Make Us Who We Are?

Nature vs. nurture is one of the oldest questions in science. The answer is not an either/or, but rather it is both nature and nurture, acting in various degrees.

As summarized below in greater detail, many workshop participants—including Hyman, Marder, and Michael Greenberg, chair of the Department of Neurobiology at Harvard Medical School—chose to highlight the nature versus nurture question as one of the Grand Challenges of the field, but in so doing, they put a twist on the question, asking: How does the interplay of biology and experience shape our brains and make us who we are?

The key word there is “interplay.” “Interplay” suggests, and modern research in neuroscience demands, that there is a back and forth pattern between nature and nurture, a dynamic system that involves a continuous feedback loop shaping the physical structure of our brains.

• Brain Plasticity

Thirty years ago, the working assumption in neuroscience was this: People are born with a set number of neurons, hardwired in a certain way, and brain function is essentially all downhill from there. We spend our lifetimes losing connections and neurons—the brain slowly falling apart until we die.

Except it is not true. In 1998, Fred “Rusty” Gage, working out of the Laboratory of Genetics at the Salk Institute, showed that the human brain can and does produce new nerve cells into adulthood ( Eriksson et al., 1998 ). In mice, he showed that exercise could increase the rate of neurogenesis, showing that the system is not fixed, but responds itself to experience and the outside world. The discovery of neurogenesis and an improved understanding of neuroplasticity—the ability of the brain to shape, form, eliminate, and strengthen new connections throughout life—has completely recast the question of nature versus nurture.

“Neurons can change their connectivity,” explained Blakemore. “They can change the strength of their connections. They can change the morphology of their connections. They can do it not necessarily just in early stages of life, although that is especially exaggerated, but probably throughout life responding to new environments and experiences.”

New research shows, for instance, that the number and strength of connections we have in the brain is determined by how often those connections are stimulated. The brain, if you will, has a “use it or lose it” approach to neurological maintenance.

Genetic programming also plays a key role. In most cases, the initial formation of a synapse occurs independent of stimulation. But if that synapse is not used, the brain will “prune” or eliminate it. Conversely, the more often a connection is used, the stronger it becomes in a physical sense, with more dendritic spines connecting to one another and a stronger net connection over time.

On the developmental side, researchers now understand the critical role that sensory input plays in shaping the wiring of the brain from the earliest days. Blakemore discussed work in his lab on the development of neural wiring in mice. Researchers have known since the 1960s that the neurons connected to the ultrasensitive whiskers of mice align themselves in a format called “barrel fields.” Each of these barrel fields is connected to a single whisker, although how or why they influence function is unknown. Blakemore showed that if you removed a clump of whiskers at an early age, the segment of the brain linked to that area never develops the barrel structure.

Similar research has shown in mice that if you tape one eye shut from birth, the mouse never gains the ability to see from that eye—it needs the stimulation to develop. However, if you tape shut the eye of an adult mouse for a similar period of time, vision is not affected.

All this seems to point the finger toward experience, but of course, the system really works as a complete feedback loop.

“We used to think . . . that the capacity of the brain to change its connections was an entirely independent process from the genetic regulation of structure,” said Blakemore. “But, of course, that cannot be the case. If adaptive change is possible, that must be the consequence of having molecular mechanisms that mediate those changes. Plasticity is a characteristic that has been selected for, so there must be genes for plasticity.”

In the case of barrel fields, Blakemore’s lab and other investigators have identified a number of molecules and genes that appear to be involved in mediating between incoming information for the whiskers and the anatomical changes necessary to produce the barrel field.

Understanding how this interplay works has huge implications for understanding how our brain develops and changes over time, and raises a number of interesting questions. Marder, for instance, asked how the brain can be so plastic and yet still retain memories over time.

Plasticity, however, is just one half of the equation; the underlying genetics are critically important, and new techniques and technologies make this a particularly interesting time to address these questions. For instance, modern, high-throughput gene-profiling technologies allow researchers to figure out all of the underlying transcriptions in a neuron, and see how these are manifest in the body.

Understanding the interplay of biology and experience on learning and development will surely require understanding the biological processes that cause changes in individual neurons and synapses. But this is only part of the puzzle. We must also understand the control of learning processes at a system-wide level in the brain. How does the brain orchestrate the right set of neural synaptic updates based on training experiences we encounter over our lifetime? Given the tremendous number of synapses in the brain, it is unlikely that a purely bottom-up approach will suffice to answer this question.

A complementary approach to studying experience-based learning at a system level relies on machine learning algorithms that have been developed to allow robots to learn from experience, described Mitchell. One intriguing study has shown that temporal-difference learning algorithms, which enable robots successfully to learn control strategies such as how to fly helicopters autonomously, can be used to predict the neural activity of dopamine-based systems in the human brain that are involved in reward-based learning ( Schultz et al., 1997 ; Seymour et al., 2004 ; Doya, 2008 ). The integration of such system-level computational models alongside new research into synaptic plasticity offers an opportunity to examine the interplay of biology and experience on learning and development from multiple perspectives.

New tools will allow researchers to understand how variability between different genes and neurons and neuronal activity could influence behavior and capabilities across different people, the researchers said. Who we are is not only influenced by the yes/no expression of genes, but also the specific levels of expression among different genes, which in turn influences neuronal activity.

• Gene-Environment Interactions

Nature and nurture are not simply additive interactions that result in a particular behavior, but rather a complex interplay of many factors. Nature includes not only the usual factors—parents, homes, what people learn—but also many other factors that individuals are exposed to routinely in their daily environments. As Marder emphasized, we cannot simply assume that gene X produces behavior Y. Instead as Bialek described, there are often many additional factors that directly and indirectly interact with gene X and ultimately influence variants in behavior. These variants define individuality.

As previously described, it has been known for almost 50 years that experience from the outside environment shapes our brain. This comes initially from the original work of Nobel Laureates David Hubel and Torsten Wiesel who studied how information is sensed and processed in the part of the brain responsible for vision. As Greenberg commented, the field is now at a point where we could in the next 10 years attain a significant mechanistic understanding of how the environment impinges directly on our genes to give rise to a malleable organ that allows us to adapt and change.

• Huge Clinical Importance

Multiple participants at the workshop—including Nora Volkow, director of the National Institute on Drug Abuse; Joseph Takahashi, investigator of the Howard Hughes Medical Institute and Northwestern University; Lichtman; and Coyle—highlighted the role of genetics in shaping the brain as one of the fundamental challenges for neuroscience, both for its basic scientific interest and for its practical applications: Understanding how genes and experience come together to impact the brain could significantly alter how we think about treating neurological disease. Many of the most common neurological and mental health disorders—schizophrenia, bipolar disorder, autism, Parkinson’s disease, multiple sclerosis, Alzheimer’s disease—are complex genetic disorders that are influenced by environmental factors.

Alcino Silva, professor in the Departments of Neurobiology, Psychiatry and Psychology at the University of California, Los Angeles, showcased research from his lab showing he could treat and reverse developmental disorders in adult mice. This finding is worth repeating because it is so contrary to our general thinking on developmental disorders: Scientists working out of Silva’s lab have been able to reverse the impacts of the developmental disorder NF-1 (Neurofibromatosis type 1), which is caused by genetic malfunction, by treating the pathology of the disease in adult mice. These mice, which have obvious cognitive deficits, regain mental function when treated; Silva has advanced the study into human clinical trials.

The applications of this vein of study extend beyond developmental disorders. A growing body of evidence is revealing a massive feedback loop among genetics, neurological structure, experience, and disease. You are three times more likely to die from a heart attack if you are depressed than if you are not, for instance, and depression has a huge impact on diabetes as well, stated Coyle.

Taking a step backward, clinical data also show that people who experience multiple stressful episodes in their lives tend to suffer from clinical depression. But there is tremendous variation: Some people are resistant to stress and others are not.

“It turns out that the pattern is correlated with a polymorphic variation in one particular gene, the gene for the transporter for serotonin, a transmitter which is known to be involved in regulating mood,” explained Blakemore.

How do genes work in the brain to determine our resilience to stress, and how can those capabilities be monitored and modulated for better health?

• The Way Forward

Asking these kinds of questions was not realistic 10 or even 5 years ago. The advent of high-throughput gene profiling and the growing sophistication of our ability to manipulate genes in animal models lets us, for the first time, explore the role that genes play in both creating and modulating our neural structures. At the same time, new imaging techniques and technologies like channel rhodopsin “light switches” let us better characterize neural systems and their response to the world around us, and to begin to plumb the tremendous feedback loop among genes, experience, and the physical activity in the brain.

Until quite recently, these have remained philosophical questions, commented Marder. However, the field of neuroscience is now in a position—through all the molecular, connectomics, and technological advances—to put these questions on firm mechanistic, biological bases, and to attack them scientifically.

Essay Sample: Nature Versus Nurture

26 March, 2020

7 minutes read

Author:  Kate Smith

This sample is a great example of the compare and contrast essay writing. It presents two points of view on what influences the development of a personality the most - genetics or environmental factors. Don't hesitate to read it to see what such a type of essay should look like when written professionally!

Nature and nurture is a hotly contested argument concerning what influences the behavior and personality attributes of individuals. Nature is entirely dependent on the genetic combination of an individual which dictates their character and appearance. On the other hand, nurture is dependent on the environmental factors that an individual gets exposed to which end up shaping his or her personality. Nature and nurture influence individuals to a certain extent because individuals get exposed to both of them in one way or the other dictating their development process.

Nature principle holds that biological characteristics of individuals get inherited from the genetic makeup in their lineage. Character traits such as height, weight, vulnerability to certain illnesses and skin complexion are inherited and determined by the genetic combination of individuals. Such biological combination is usually similar amongst individuals who are blood relatives, and for this reason, they tend to have almost a uniform genetic combination. Moreover, other behavioral, mental and personality attributes are also a reflection of our genetic makeup and usually inherited from individuals’ close blood relatives (Kong et al. 2018). Through the traits, it is easier to identify closely related individuals just by looking at their appearance and conduct.

Besides, specific characteristics do not become evident during birth, and when a person reaches a certain age, for instance, during puberty, that is when the hidden attributes begin showing up. The biological clock guides such characteristics, and when the right time comes, the physical and behavioral attributes mature and become conspicuous. Such traits get programmed in a way that for them to grow visible, they will take a certain period to develop. Moreover, they are also dependent on other biological factors within our bodies for them to manifest. However, the traits still maintain the genetic combination and the similarity of a specific lineage.

On the contrary, through nurture, an individual acquires specific attributes from the environment that surrounds them. When a child is born, for instance, its mind is black and empty. It is through its interaction with the surrounding and the people around it that will make the infant acquire some of their traits through learning, observation and aping their conducts. In other words, nurturing is dependent on the environment, experience, and learning as the individual interacts with the environment with time (Vazsonyi, Roberts, Huang & Vaughn, 2015). The way an individual was nurtured or brought up will influence their aspect of child development. Maturation will only affect biological development. The environment plays a vital role in the development process.

Similarly, the type of relationships also plays a crucial role in the nurturing, especially during child development. For instance, an infant develops an emotional attachment to its parents because of the love and affection it receives. Moreover, children who are given proper care and affection will reciprocate the same while growing up. On the contrary, infants who receive harsh treatment from their parents will develop withdrawal symptoms while growing up. Also, the infants also try and learn how and what to talk by studying the speech of those around them. The cognitive development comes from the exposer that the infant receives and conditions surrounding it.

Correspondingly, certain traits are acquired based on what an individual went through. Children who got abused or molested when growing up develop specific antisocial characteristics, for instance, being high tempered, harsh and develops particular disorders. For example, bipolar disorders manifest because an individual underwent harsh treatment which affects their psychological stability after that. Some of them become abusers and molesters in their future relationships as a way of imitating and justifying what they experienced while growing up. Imitation is a way of implementing what the individual has learned during the nurturing process by putting the lessons into practice.

Striking a Balance

However, after careful analysis, psychologists have discovered that both nature and nurture are responsible for the development of an individual. Both factors interact with each other and play a crucial role in shaping up the conduct of an individual (Lux, 2014). For example, in psychopathology, it is argued that both hereditary factors and environmental conditions contribute to the development of mental disorders in individuals. The biological combinations of people closely interact with the socio-cultural set up surrounding them. Individuals are now left to make their own choices in dictating what is suitable for them and what should be left out. Nature and nurture complement each other in shaping an individual.

Conclusively, nature and nurture are broiling discussion, and both sides have valid points to justify their stands. Nature is purely based on the fact that genetic makeup influence how an individual behaves and thinks. Similarly, the natives hold that genetic factors dictate factors such as the appearance, particular illness, and intelligence levels. On the contrary, individuals who believe in nurturing hold that environmental factors are majorly involved in the development process of individuals. Children acquire traits through learning from the people surrounding them and will try to imitate the behavior after that. However, psychologists are trying their level best to strike a balance between the two school of thoughts since both sides hold valid arguments, but both nurture and nature interact with each other during the development process. Nature and nurture cannot get treated in isolation.

Sample critical essay on nature vs. nurture.

Select network

There has long been a debate about whether nature or nurture matters more in determining the traits an individual will have. In other words, do genetics or environment play a more formative role in the development of one’s personality? Nature says that our traits are influenced by genetic inheritance and similar biological factors while nurture is meant as the influence of environmental factors after conception.

We know that physical characteristics like eye color, hair color, and height can be attributed to specific genes within our DNA. But what about emotional or behavioral traits?  This sample biological essay from the essay writing services at Ultius examines the question that while some behavioral traits can be traced to certain genes, does our environment play a role in activating those genes?

Our genetic makeup

Science tells us that certain traits are most definitely attributed to genetic causes. Our eye color, skin pigmentation, and certain diseases like Tay-Sachs or Huntingdon’s chorea are all direct results of the genes we inherit from our parents. Other traits to which we can be genetically predisposed include weight, height, life expectancy, hair loss, and vulnerability to certain illnesses (McLeod 2007). Because these characteristics can be definitively connected to our biology, many speculate on whether or not genetic factors can contribute to behavioral tendencies, mental abilities, and personality traits .

Nativists, those who believe that every characteristic we have is determined only by nature, assume that the characteristics of the human species as a whole are simply a product of evolution and that the things that make us unique are a result of our own specific genetic code. They believe that the characteristics that are not observable at birth, such as personality traits, emerge later as the product of maturation.

We each have a biological clock inside us that turns certain behaviors on and off in a way that is preprogrammed from birth. An example of this would be the way our bodies change during puberty. Nativists also believe that:

“maturation governs the emergence of attachment in infancy, language acquisition, and even cognitive development as a whole” (McLeod 2007).

Bowlby’s theory of attachment views the bond between the mother and child as being an innate process that aids in our survival as a species. Likewise, Chomsky believed that language is learned through the use of an innate language acquisition device that all humans are born with (McLeod 2007). In addition, Freud speculated that traits like aggression are engrained in our DNA. 

Fraternal twins as evidence of nature over nurture

Similarly, it is often debated whether or not criminal activity can be linked to a genetic disposition. One of the biggest pieces of supporting evidence for the nature over nurture is the fact that fraternal twins exhibit similar characteristics even when they are raised apart. Often times, these twins will share behavioral traits as if they were raised together in the same place. Mental health is undoubtedly affected by our biological dispositions.

For example, bipolar is approximately five times as likely to develop when there is a family history of the condition (“Nature vs. Nurture Debate”). There are similar statistics available for a wide number of mental health conditions . Researchers also tend to place more emphasis on nature when it comes to addiction. Alcoholism, for example, can recur in families and it has been found that certain genes may influence the development of alcoholism and the way alcohol effects the body.

Alternatively, to nativists, empiricists believe that the human mind is a blank slate at birth and any characteristics we develop are a result of our experiences and environment. With point of view speculates that psychological characteristics and our behavioral tendencies are things we learned during our development. While the concept of maturation applies to the biological development we experience, any psychological growth is a result of the way we are brought up.

Attachment of infants as evidence of nurturing

An example of this would be the way infants form attachment. The formation of attachment is a direct result of the love and attention a child receives. If they are not given love and attention, the attachment will not develop. Similarly, we learn language by mirroring the speech we hear from others.

Our cognitive development is dependent on the environment and civilization in which we are reared (“Nature vs. Nurture”). Bandura’s social learning theory states that aggression is a characteristic that we learn through observation and imitation. In addition, Skinner believed that language is something individuals learn from others via behavioral shaping techniques.

Watson's ideas on environmental learning

John Watson, one of the most well-known psychologists to propose environmental learning as the dominating factor in the nature versus nurture debate, feels that our behavioral traits are purely a result of our surroundings and experiences. He felt that he could condition a new behavior in a child or alter an already existing behavior that is considered to be unfavorable (Sincero 2016).

Watson believed that he could randomly choose any baby out of a group of twelve infants and raise the child to become any type of specialist he chose. He stated that he could train any child to be anything, regardless of the individual’s talents, potentialities, and social groups.

Benefits of nurturing on mental health

Just like nature, nurture affects our mental health, as well. While someone may have a genetic disposition for one condition or another, there still needs to be an environmental trigger for that condition to develop. If there is a genetic indication that a mental condition may develop, the individual can be ‘nurtured’ in a way that can prevent the condition from developing or lessen its severity.

A neuroscientist named James Fallon discovered that he possessed the brain of a psychopath and believed that being raised in a loving and nurturing environment helped ensure that he never fully developed enough sociopathic traits for them to affect his success (“Nature vs. Nurture Debate”).

The foundations of addiction

In a similar way, the basis for addiction is not entirely determined by genetics. Certain environmental aspects, such as the habits of our friends, partners, and parents, can contribute significantly to the development of addiction. A genetic predisposition to alcoholism becomes entirely more significant when the individual in question is frequently exposed to alcohol abuse and comes to view the harmful behavior as normal.

A study conducted at the University of Liverpool found that a family history of mental health conditions was only the second strongest indicator that a mental condition would develop (“Nature vs. Nurture Debate”). The strongest predictor was life events and experiences that contributed to the development of the mental condition, such as abuse, bullying, or childhood trauma.

Meeting in the middle

Today, most people agree that our characteristics are a result of a combination of both nature and nurture. There is enough support for both sides to completely count either side out. For example, if one twin develops schizophrenia gene , the other twin has only a fifty percent chance of also developing the same condition (“Nature vs. Nurture Debate”). Clearly, both nature and nurture can affect the development of certain disorders.

The question then shifted from ‘which one’ to ‘how much?’ We know that both play a role, but which force is more important? Francis Galton was the first to pose this question during the late nineteenth century. A relative of Charles Darwin, he felt that intellectual ability was mostly attributed to genetics and that the tendency for genius to be a familial trait was the result of natural superiority (McLeod 2007).

Arthur Jenson on intelligence testing

Many others have agreed throughout history, which has spurred an influx of intelligence testing; in particular, on separated twins and adopted children. Arthur Jenson is an American psychologist who is a modern proponent of nature over nurture. Jenson cites average IQ scores in which black Americans scored significantly lower than white participants and suggested that as much as eighty percent of intelligence is inherited (McLeod 2007).

Not surprisingly, controversy developed surrounding Jenson’s claims due to the logical weakness of his argument. It was widely agreed that his study was tainted by social and political implications that are often drawn from various studies that claim to represent natural inequalities between race and other social groups. Differences in IQ scores between various ethnic groups can be explained by biases in testing methods and social inequalities in access to resources and opportunities (McLeod 2007). Similarly, it is hotly debated whether or not alleged intelligence difference in male versus female results is a consequence of biology or culture.

The importance of both nature and nurture

Now, however, the scientific world has come to understand that trying to place a numerical value on nature and nurture to judge which is more important is not really the right approach (Davies 2001). Intelligence, for example, is a complex human characteristic that can exhibit itself in a wide variety of ways from genius to basic common sense .

By attempting to place quantitative values on the separate factors, we fail to focus on the fact that biology and environment interact in a host of important and intricate ways (Ridley 2003). Today, most people agree that neither biology nor environment act independently of one another. Both are necessary for any characteristic to manifest. Because they are dependent on each other and interact in such a complex manner, it is illogical to attempt to think of them separately. 

How nature and nurture combine in the individual

Rather than defending nativists or empiricists, most psychologists are now more interested in researching the ways in which nature and nurture interact with each other to develop characteristics and traits. In psychotherapy, this means that not only does there need to be a genetic disposition required for mental disorders to develop, but there also needs to be an environmental trigger, as well (Feller 2015).

The recognition of this important relationship is especially important given the genetic advancements made during the twenty-first century. The Human Genome Project and advent of bioengineering sparked wide interest in tracing types of behavior to particular strands of DNA found on certain chromosomes (McLeod 2007). Scientists expect to soon find specific genes that are linked to criminality, alcoholism, and other characteristics.

Conclusion 

Psychologists have been debating the influence of nature versus nurture over human characteristics for a very long time. After the scientific world came to recognize that biology and environment both play a role, the emphasis shifted to determining which was more important. Now though, as we have come to truly understand the complexity of the relationship between our genetic dispositions and environmental triggers, we no longer focus on one versus the other, but rather the way they interact with and affect each other.

While it is certainly helpful in the development of certain conditions for there to be a genetic disposition, there almost always needs to be an environmental trigger that causes the characteristic to manifest in an individual. This is only a small part of this complex discussion and an example of what you can expect when you buy a critical essay from Ultius.

‘Evil Does Not Exist’ Review: Nature vs. Nurture

Ryusuke Hamaguchi follows up his sublime drama “Drive My Car” with a parable about a rural Japanese village and the resort developer eyeing its land.

• Share full article

By Manohla Dargis

Late in “Evil Does Not Exist,” a man who lives in a rural hamlet an easy drive from Tokyo cuts right to the movie’s haunting urgency. He’s talking to two representatives of a company that’s planning to build a resort in the area that will cover a deer trail. When one suggests that maybe the deer will go elsewhere, the local man asks, “Where would they go?” It’s a seemingly simple question that distills this soulful movie’s searching exploration of individualism, community and the devastating costs of reducing nature to a commodity.

“Evil Does Not Exist” is the latest from the Japanese filmmaker Ryusuke Hamaguchi, who’s best known for his sublime drama “Drive My Car. ” This new movie is more modestly scaled than that one (it’s also far shorter) and more outward-directed, yet similar in sensibility and its discreet touch. It traces what happens when two Tokyo outsiders descend on a pastoral area where the spring water is so pure a local noodle shop uses it in its food preparation. The reps’ company intends to build a so-called glamping resort where tourists can comfortably experience the area’s natural beauty, a wildness that their very patronage will help destroy.

The story unfolds gradually over a series of days, though perhaps weeks, and takes place largely in and around the hamlet. There, the local man, Takumi (Hitoshi Omika), a self-described jack-of-all trades, lives with his daughter, Hana (Ryo Nishikawa), in a house nestled amid mature trees. Together, they like to walk in the woods as she guesses whether that tree is a pine and this one a larch, while he carefully warns her away from sharp thorns. A photograph on their piano of Hana in the arms of a woman suggests why melancholy seems to envelop both child and father, although much about their past life remains obscure.

Hamaguchi eases into the story, letting its particulars surface gradually as Eiko Ishibashi’s plaintive, progressively elegiac score works into your system. The company’s plans for a glamping site give the movie its narrative through line as well as dramatic friction, which first emerges during a meeting between residents and the company reps, Mayuzumi (Ayaka Shibutani) and her brash counterpart, Takahashi (Ryuji Kosaka). The company — its absurd name is Playmode — wants to take advantage of Covid subsidies for its new venture. During the meeting, it emerges that the site’s septic tank won’t be large enough to accommodate the number of guests; the locals rightly worry that the waste will flow into the river.

The scene, one of the longest in the movie, is emblematic of Hamaguchi’s understated realism, which he builds incrementally. The meeting takes place in a basic community center crowded with residents — some had dinner at Takumi’s home the night before — who sit in chairs facing the reps, who, armed with technology, are parked behind laptops and seated before a projector screen. As the reps play a video explaining “glamorous camping,” there’s a cut to Takumi intently watching the promo. The scene soon shifts to a tracking shot of deer tracks in snow and images of Hana playing in a field as a bird soars above; it’s as if Takumi were thinking of his joyful, distinctly unglamorous daughter. The scene shifts back to the meeting.

The site will become “a new tourist hot spot,” Takahashi sums up, badly misreading his audience. “Water always flows downhill,” a village elder says in response, his thin, firm voice rising as he sweeps an arm emphatically downward. “What you do upstream will end up affecting those living downstream,” stating a law of gravity that’s also a passionate, quietly wrenching argument for how to live in the world.

Lapidary, word by word, detail by detail, juxtaposition by juxtaposition, “Evil Does Not Exist” beautifully deepens. For the most part, the movie is visually unadorned, simple, direct. Hamaguchi tends to move the camera in line with the characters, for one, though the exceptions carry narrative weight: images of nearby Mount Fuji; a rearview look from inside a car at a fast-disappearing road; and a lovely traveling shot of soaring treetops, their branches framed against the sky. The canopied forest echoes an image in a short film by Masaki Kobayashi , who began directing after World War II; the title of his trilogy, “The Human Condition,” would work for every Hamaguchi movie I’ve seen.

I have watched “Evil Does Not Exist” twice, and each time the stealthy power of Hamaguchi’s filmmaking has startled me anew. Some of my reaction has to do with how he uses fragments from everyday life to build a world that is so intimate and recognizable — filled with faces, homes and lives as familiar as your own — that the movie’s artistry almost comes as a shock. The dreamworld of movies often feels at a profound remove from ordinary life, distance that brings its own obvious pleasures. It’s far rarer when a movie, as this one does, speaks to everyday life and to the beauty of a world that we neglect even in the face of its calamitous loss. When Takumi asks “where would they go,” he isn’t just talking about deer.

Nature Versus Nurture and Learning Among Children Essay

The debate on the impact of heredity and environment on the growth and development of human beings has been going on for a long period of time now. Researchers have traced this ageless debate to as long a time ago as the 13 th century. This implies that human beings, particularly researchers are yet to reach a consensus on the significance of nature and nurture on human development.

Those who support the role of nature in human development argue that all behaviour is dictated by genetic or hereditary predispositions that are encoded from the time of conception (Plomin, Corley & Defries, 2007 443). The proponents of the role of nurture in the development of human behaviour emphasise the role of environment in which they are brought up in (Gopnik, 2004 1).

The essay seeks to explore the nature versus nurture debate in relation to the provision of appropriate learning experiences for children. It will then conclude that much of a child’s learning is influenced by both environmental as well as heredity factors.

Psychological researchers have been engaged in an unending debate on whether a child’s development is directly influenced by heredity and other biological factors or it is by the environment in which the child is born and raised. Both sides have advanced undisputable evidence to support their respective sides.

Of much concern among modern researchers is the determination of the degree of influence of nature and nurture on the development of a child and the provision of learning experiences (Gopnik, 2004 3). We shall focus on the impact of both sides of the debate on the child’s learning.

The advocates of the nature theory of human behaviour argue that a child is born with inherent genetic traits that play a central role when it comes to the general development of the child.

They propose that nature provides the child with the necessary capabilities and capacities required for meaningful learning (Plomin et al., 2007 444). According to Gopnik, a renowned professor of psychology, it is by nature that a child is able to learn and influence the environment and interact with it as well (2004).

She argues strongly against the proposal by John Locke who said that a child is born with a blank mind known as “tabula rasa” on which experiences write on it (Plomin et al., 2007 449). Some of the qualities that have been identified as hereditary include; a persons height, behaviour, and intelligence quotient (IQ), among others.

Investigations conducted by nature theorists on twins who were raised in different environments revealed that they could still exhibit notable similarities. The findings further indicated that measures of personality as well as that of temperament, leisure-time and occupational preferences, and attitudes towards social life were much similar among the twins (Plomin et al., 2007 451).This study, therefore, supports the argument that nature plays a great role in child development.

To contrast, another study was conducted on adopted children who shared the same family environment but no genetic relationship. The findings revealed very minimal similarities among the children, but significant similarities with their actual parents (Gopnik, 2004 23). This emphasises the role of genetic factors in the growth and development of human persons.

With the revelation of the key role that nature plays in child development, educators are enlightened on the appropriate learning experiences that they should provide to individual children (Plomin et al., 2007 453). Understanding the child’s background is therefore crucial in ensuring that the child is exposed to the proper experiences as well as detecting any disabilities that may hinder learning. This knowledge helps teachers and parents in designing appropriate learning experiences for each child early enough (Gopnik, 2004 437).

On the other hand, the role of the environment in shaping human behaviour has received as much support as that of heredity. Scientists have established that the way a child is nurtured can help in determining the child’s general personality/capabilities and behaviour (Plomin et al., 2007 454). They have concluded that most behaviours and habits can be learned from the surrounding in which one is brought up.

The diet that a child is given, for instance, has been demonstrated as influencing the development of some capabilities. A study conducted by psychological researchers where some children were given food enriched with vitamins and minerals revealed significant impact of nutrition on intellectual development (Gopnik, 2004 56). The children scored higher on the same nature of intelligence tests that had been given before.

A group of children who had been put on diet which had not been enriched recorded no meaningful improvements on the same intelligence tests (Plomin et al., 2007 455). Apart from enhancing intellectual capabilities, the researchers noted that it was logically correct to conclude that nutrition impacts on the physical capabilities as well.

Nurture theorists further illustrate that if a child is brought up among wild animals, the child would never develop normally when eventually brought back to live among human beings (Plomin et al., 2007 457).

This argument points to the fact that social behaviour is learned from interaction with other people. For educators, the knowledge of the role of environment in shaping behaviour helps them in developing an environment that is conducive for learning in order to facilitate meaningful development (Plomin et al., 2007 458). John Locke, a renowned advocate of the nurture theory regarded a child’s brain as a blank slate where experiences were to be written upon.

This theory also notes that skills like listening, attentiveness, and following instructions are learned from the environment and determines success in school. Hence, educators have realise that a child must be provided with proper experiences that will facilitate the acquisition of crucial qualities that will in turn enhance learning (Gopnik, 2004 87).

The essay has focused on the two sides of the nature/nurture debate and how each plays a role in the development of human behaviour. It is clear that some qualities are inherent in an individual and are independent of environmental influence. On the other hand, some qualities can be enhanced by the exposure of a child to an appropriate environment.

With these considerations in mind, educators must appreciate the role of both genetic as well as environmental factors in child development. Appropriate learning experiences that enhance both of these need to be provided right from childhood.
