When it comes to Behavioral genetics, it is one of the two important areas of biopsychological research (Pinel, 2014). Behavioral heredity is applicable with observing of the varieties show in diverse people, and it tries to assess the near impacts of heredity and surroundings in deciding the same. Indeed, the most personality speculations (like Twins and Adoption based studies) accept that such refinements are represented by a hereditary variable; however behavioral geneticists suggest that distinctive divergences are controlled by a cluster of complex components not by direct heritability gauges. According to class readings, to assess the relative contributions of genes and experience to the development of differences in psychological attributes, behavioral geneticists study individuals of known genetic similarity (Pinel, 2014). To comprehend it plainly, we have to think over the conclusion drawn by Larsen and Buss that despite the fact that a few qualifications present around people could be because of hereditary divergences, yet the pretended by environment in adjustment of thei...
In a study conducted in 1983, researchers studied more than 350 pairs of twins in order to research if human personality traits were largely inherited or learned. Daniel Goleman, author of “Major Personality Study Finds that Traits are Mostly Inherited,” shares with his audience the parameters and results of this elaborate twin study. Goleman introduces his reader to Auke Tellegen, a psychologist and principal researcher on the long-term study, performed at the University of Minnesota, discovered that the human traits most strongly determined by heredity were leadership, obedience to authority, and even traditionalism. He would surely argue that heredity, more than influence of experience, is more responsible for development in human traits. Tellegen may have substantiating facts that nature is more predominant in a mere handful of traits, but what about the several other traits he failed to test? It is possible for a person who shows leadership and obedience during one part of their life to have an experience in which their obedience and leadership is thwarted. The study Tellegen conducted could not have been without environmental influence. Every single one of the participants, whether a twin or not, had environmental experiences separate from the others. Since every person experiences and responds to environmental stimuli differently, how can several prior years of experience be measured in order to present an unbiased result in this study? Unquestionably, it is impossible. Just as this particular study failed to take into consideration a persons’ prior experiences, it also failed to consider the probability of future environmental factors that could affect the traits Tellegen focused on in his study. Although difficu...
In psychology, the nature versus nurture argument is a long-debated topic. With each new discovery, there are two famous questions, "Did genes make this happen or did one's environment cause it?" Torgersen (2009) confronts this battle by gathering data of the effects of the environment on the development of personality disorders, explaining that – due to research in Norway and other regions – the progression and endowment of personality disorders may actually boil down to genetic predisposition rather than environmental factors. In other words, it is suggested
What makes us who we are? Does the answer lie in our genes, our environment, or in the way we are raised? For years, there has been an on-going debate between nature and nurture. T.H. White, author of The Once and Future King, explores the debate through many of the book’s characters. The issue clearly appears in the relationship of Queen Morgause and her sons, the Orkney brothers. The debate caused people to pick a side, to pick nature over nurture, or nurture over nature. However, it does not have to be one or the other. Nature and nurture work together to determine who we are.
The debate of nature vs. nurture continues today in the world of psychology. The effects of an individual’s genetics and the effects of their environment on their personality and actions is an age old debate that is still inconclusive. However, it is evident that both sides of the argument carry some form of the truth. It can be contended that the major characteristics of an individual are formed by their environment, more specifically, their past experiences. An individual’s past moulds and shapes their identity, if they do not make an effort to move on from it.
A layman would define personality as an individual’s characteristics in terms of how they think and behave. Many theorists, however, interprets personality differently resulting in various personality theories. Personality is determined by traits which are behaviours displayed by a person in most given situations. How a person reacts to common circumstances may also be used to foresee future behaviours. Traits are then categorized into types that allow easier comparisons to be made between each individual’s attributes. The focus of this paper would be on the biological aspects of personality whereby traits are thought to be inheritable through genetics and associated with the central nervous system. Behavioural genetics are research that makes use of results from studies done on family, twins and adoptions. The findings of how both genes and environment influences personality from the studies will be discussed. Some researchers found possible issues with the representativeness of such studies. The outline of Eysenck’s biological model of personality and arousal, Gray’s BAS/BIS theory and Cloninger’s biological model of personality will further explain the biological effect on personality.
While genetics define what we are going to be like in a physical way, psychology defines our more personal si...
Studies have proven that no human being is born with knowledge or skills; however, every individual’s has a learned behavior that is either influenced or genetic inherited. Therefore, every individual born into a social and cultural environment are more likely to be effected by, family members, other social groups, religion, as well as languages. Most research psychologists study the genetic inheritance of an individual’s behavior while others focus on an individual’s development stage. However, during the process of psychological research, psychologists also focus on examining the influence that a community can have on one social behavior.
The main idea behind this paper was to answer this question: "Who are you?" The article makes you think about how psychologists are able to determine whether a trait being physical or psychological is hereditary, is it taught over your upbringing by your parents, or is that just part of your own personal make up. The article states that “most humans feel that the way that they act and perceive the world is built around an environmental basis rather than being a genetic trait. ”(Are You a Natural)

Raymond B. Cattell (1906-1998) studied the personality traits of large groups of people, calling the visible features of their personalities “surface traits.” During his studies, Cattell observed that certain “surface traits” would appear simultaneously in individuals. When Cattell noticed this trend occurring frequently he renamed the group of “surface traits” “source traits”. At the conclusion of his research Cattell identified sixteen “source traits.”
Behavioral genetics is a field of research that investigates the relative effects of heredity and environment on behavior and ability (Plomin, 1997). Two of the primary methods used by behavioral geneticists are the twin study method, first used by Galton (1975) in his studies of heredity, and the adoption method.
... have come to the conclusion that genetics is very important for the development of personality but even they have to determine how these genes are investigated for the purpose of determining a particular personality. “What scientists have found is that there does not appear to be a single gene for a particular trait, but that genes show their effects by working together in complex combinations. For example, there is no single gene for dancing or music. Whether a child will be musically inclined will be determined by the way that child's genes interact with one another. Some parents would like to believe that by creating an environment rich in music while the child is young will develop the child's talent towards music. However, despite assumptions like this, there is no evidence that shows long term effects of growing up in a particular environment” (Pinker, 2003).
The Biological approach to personality places emphasis on the genetic influences related to the development of an individual’s personality. Some may believe that children and their parents can have very similar personalities, for example a young boy having his father’s anger (Stelmack, 1990). Though this approach has often been questioned by psychologists, it is not disregarded all together. Some believe that genetics do have a role in an individual’s personality development; however environments, as well as personal experiences all work in forming personality.
During the 1920’s Alfred Adler began research into a topic that would forever impact the behavioral sciences; he studied the role of one’s birth order and how it influenced personality (Eckstein & Kaufman, 2012). This concept arouses my interest because of how personal it is to me; I come from a larger family and witnessed the very traits they discuss in the article in my siblings and myself as well. Indeed I am a firm believer that birth order is significantly related to presence of certain personality traits in a person because of the different experiences and parenting styles each child grows up with. Additionally, I have devised my own type of principle relating to middle children, like myself, in larger families with lengthy age gaps.
