It can be tempting to simply dismiss the debate as academic: those who study genetic influences on behavior would probably say that, if genes do influence behavior, it is only through an intricate process that we have only begun to understand. For example, when a person achieves tremendous academic success, did they do so because they are genetically predisposed to be successful or is it a result of an enriched environment? Thus, any differences found between identical twins can be attributed to the environment i. Others might point to the nurturing that took place in the home as the child was raised. It is one of the reasons for the eternal debate of nature vs nurture exists. The fact is, that both go hand-in-hand and one cannot work without interacting with the other; and thus both play more or less an equal role in shaping how you behave.
Also, siblings are more similar in personality than adoptive siblings. Any variance that is not due to genes is by definition due to environment Steen, 1996. Other adoption studies examine individuals who are genetically related to one another, but they are raised in different environments. Extremes analysis examines the link between normal and pathological traits. Nurture on the other hand is those things that are influenced by the environment we live in. Transmission of aggression through the imitation of aggressive models. High blood pressure and obesity An example of this debate is whether high blood pressure and obesity is a health risk that is passed genetically from parent to child.
Twin studies established that there was, in many cases, a significant heritable component. Although there is no direct reference to the discussion in the article, the general conclusion of Boas is unambiguous and clear: presumably the fixed biological characteristics of a particular race are capable of changing depending on local conditions. They saw themselves in the vanguard of science, warning politicians, doomed to failure in their attempts to ensure universal equality. Not that those who conclude that intelligence is inherited are racist, but that conclusion has in the past been partly motivated by racist beliefs against immigrants. As you can see, this is popular. Someone could be born with genes to give them a normal height, but be malnourished in childhood, resulting in stunted growth and a failure to develop as expected. The nature versus nurture debate is one of the oldest issues in psychology.
It is an unending discussion and if you are faced with the challenge of writing a nature vs. Future research on environmental factors will focus on the importance of nonshared environments and how different children in the same family might experience the same environmental stimulus in different ways, thus having a very different influence on their development. In animals where breeding and environments can be controlled experimentally, heritability can be determined relatively easily. The only thing that would change would be the date, which will change when we update the page in the future. Today, most psychologists take an interactionist approach that views both nature and nurture as being important in development.
A modern proponent is the American psychologist Arthur Jenson. Mental health conditions like bipolar have a higher rate of development if the individual has a family history of it. However, the issue still rages on in many areas such as in the debate on the origins of homosexuality and influences on intelligence. Bipolar, for example, is four to six times more likely to develop when there is a family history of the condition. Twin Research and Human Genetics, 16 1 , 117-125.
The main argument is, if there are that are and developed before birth, then one should expect twin foetuses to engage in some form of before they are born. A person's ability to perform in a certain occupation also leads to a nature versus nurture debate. However, behaviorists in the mid-20th century revived nurture and claimed that all human behaviors were acquired through conditioning. Oxford biologist found out that primate species tended to have the same social structure as their close relatives, regardless of how and where they live, suggesting that the similarity in social structures of related species may be due to genes inherited from a common ancestor. Since then we have looked into how the human mind and body works, with subjects like intelligence, personality, memory, sense and perception, and lifespan development, amongst others. Similarly in other fields, the dividing line between an inherited and an acquired trait becomes unclear, as in or.
Nurture has also influenced us! Aristotle, Rousseau and Darwin, and I all have different opinions on the nature verses nurture debate. In the battle of nature vs. Nature and nurture: An introduction to human behavioral genetics. I had to be, I wasn't like my sisters at all. What about the opposite side? Nature, or genetics and disposition, has been proven to be an important factor in the development of some mental health conditions, such as , , and major. The authors deny this, requesting that evolutionary inclinations be discarded in ethical and political discussions regardless of whether they exist or not. Nature supports the idea that our character traits are influenced by genes and biological factors whereas nurture is of the opinion that the environment and surroundings after conception help in determining the personality of an individual.
Nurture proponents believe that homosexuality is a choice or a behavior influenced by environmental factors. The ability to pick up different speech sounds, and learn a language, amongst other things is genetic and is seen in all babies, irrespective of their environmental conditions. Other debates center on the roles of genetics and personal habits in health risks such as obesity and high blood pressure. Certain genetic factors can also decide how an individual interacts with their environment. How Nature Affects Mental Health While nature, or genetics, has been proven to be an important factor in the development of some mental health conditions, such as schizophrenia, bipolar, and major depression, the development of mental illness is not entirely genetic. The nature versus nurture debate involves whether human behavior is determined by the environment, either or during a person's life, or.
