To What Extent Does Genetic Inheritance Influence Behavior?

One of the oldest debates in the history of Psychology is about Nature versus Nurture. Today, we know that both play a significant role in human’s life. Some people believe that it is genes which affects our way of life and some people believes that it is none other but our environment that greatly influences our lifestyle and some believe that both has tremendous impact on one’s way of life. Indeed in certain cases both our nature (our genes) and our environment roughly play an equal role in human life.

“Trying to separate out nature and nurture as explanations for behavior, as in classic genetic studies of twins and families, is now said to be both impossible and unproductive” (Levitt, 1). Social scientists have declared the nature-nurture debate to be unnecessary. Similarly, scientists feel that such debate is not only unhelpful, but also outdated. From geneticists’ perspective, nurture and nature interact to influence

The question of whether we are more heavily influenced by our surroundings and/or our upbringing as opposed to what comes naturally to us is a very controversial ongoing debate. This examination can be seen in the 1965 experiment known as “The John/Joan Case”, intended to test the theory of “Nature vs Nurture”. This dispute within psychology is concerned with the extent to which particular aspects of behavior are a product of either inherited or acquired characteristics. “Nature is all that a man brings with himself into the world; nurture is every influence without that affects him after his birth.” (Galton)

The classic debated topic of Nature versus Nurture has been and will always be a quarrelsome subject in the scientific world. Meaning, the issue of the level to which environment and heredity sway behavior and development in a person. Nature can be defined as, behaviors due to heredity. This means the behaviors is based on the inherited makeup of an individual and is an influence of the growth and development of that individuals’ all through life. On the other hand nurture is causes of behaviors that are environmental. This Intel’s the influence is from the individual’s parents, siblings, family, friends and all other experiences that individual exposed to during life. However, these concept of ideas supports the inborn genetic framework,

Human behavior is affected both by genetic inheritance and by experience. The ways in which people develop are shaped by social experience and circumstances within the context of their inherited genetic potential. Each person is born into a social and

Advances in science today suggest neither nature nor nurture is exclusively responsible, but instead an interactive relationship between our genes and environmental influences. The influence that nurture has upon nature is a new and blooming field called behavioral epigenetics.

Theoretical Propositions: The question of why people are who they are and why they behave the in the way that they do was asked. The researchers wanted to understand if people develop into who they are primarily from factors in the environment or because of there genetic makeup. In the second half of the 20th century most psychologists agreed in the theory of behaviorism, human behavior is caused only by factors in the environment. This study would answer the common “nurture vs nature” question that many people still ask today.

Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.

This essay will outline and compare both biological and behavioural perspectives on human behaviour. The history, major discoveries and theories will be discussed along with some of the most influential theorists in each of these two areas of psychology. This essay will also compare the two areas strengths and weaknesses in the field of psychology.

Across studies of 10,000 twins, the intelligence test scores of identical twins reared together are virtually as similar as those of the same person taking the same test twice…Likewise, the test scores of identical twins reared separately are similar enough to lead twin researcher Thomas Bouchard (1996) to estimate that ‘about 70 percent’ of intelligence score variation ‘can be attributed to genetic variation. (p. 455)

The world of Genetics is one that is both fascinating and interesting. When tackling how genetics plays a role in behavior, one must look within the scope of what genetics is before dealing with how it plays a significant role in one’s behavior. Simply put, genetics is the study of genes. It is a biological component within the entire study of biology itself. Scientists who study genetics and perform research do so with the intent to learn more about how genetics affects the overall attitudes, behaviors and dispositions of individuals. It could be said that genetics is somewhat of a psychological-biological science as researchers look at the underlying patterns within the genes that cause

Is behavior learned? It is inborn? What of aggression, intelligence, and madness? There is a crucial relationship between the behavior of humans toward their own kind and the view of life they hold. Interest in behavioral genetics depends on wanting to know why people differ. According to Jack R. Vale, in Genes, Environment, and Behavior, recognition of the importance of hereditary influence on behavior represents one of the most dramatic changes in the social and behavioral sciences during the past two decades. A shift began toward the more balanced contemporary view that recognizes genetic as well as environmental influences on behavior. Behavioral genetics lies in its theory and methods, which consider both genetic and

The development of human being during the entire course of life, focus on biological and psychological growth (Berk, 2010). Human development hold several outcomes that are altered by both positive and negative influences. Genetic (nature) and environmental (nurture) influences place significant impact on human development. In fact, Pinker (2004) submits that behavior is the result of a complex collaboration among inheritance and environmental factors in human development, ultimately supporting that nature-nurture work collectively (Pinker, 2004).

Over the years, psychologists have been concerned with determining the relative amount contributed by genetics or environmental factors to different behavior. They also often ask the

Scientists still agree that biology does play a part in human behavior, however. Nature and nurture do not oppose each other in every manner. Today, social scientists hesitate to choose one or the other. As humans, life depends solely on the operating of the body. This is seen especially in children. It is obvious that children share their biological traits, such as hair or eye color, with that of their parents. Heredity also plays a part in their intelligence, how artistic they are, and their overall personality. We all have “potential” inheritances, in which their full development depends on how we are all raised. Both sides
