Nature vs Nurture

Identical twins are many times seen as genetic reproductions representing variations from twin to the other twin and are created because of environmental factors (Cervone & Pervin, 2010). Since identical twins share identical genetics, his or her personality seems to also share similarities. Moreover, the environment can impact fraternal twins, resulting in fraternal twins personalities and his or her characteristics similar to each other. For example, identical twins. Some research shows twins that are raised in the same residence have little differences from those who are raised in a different home.

What determines who you are or what you will become? The debate between nature versus nurture is trying to figure this out. According to “Essentials of Psychology”, Jeffrey S. Nevid (2012) Nature versus nurture is the debate about how genetics and nature determine our behavior. In other words, have your attitude, behavior and health problems developed because of how you were raised or who you came from. It is a debate that has stumped psychologists for centuries. The study of twins, both identical and fraternal, have made it easier for psychologists to figure out this debate. So what is the answer to this age old debate; Nature or Nurture?

How did your temperament flourish? The phrase nature and nurture relates to the relative importance of an individual's innate qualities as compared to an individual's personal experiences in causing individual differences, especially in behavioral traits. This debate is basically deciding if your genetics have more effect on you or society. Hereditary and environmental elements both frame identity. Identical twins are different in many ways. Personality changes over time. Studies have also shown that nurture is more dominant than nature in shaping personality. Nurture is definitely extra dominant in molding your identity.

Nature or Nurture. Nature may be all of the genes and hereditary factors with which influence them to become who they are such as physical appearances and personality characteristics. Nurturing impacts people’s lives as well as how they are raised and all the environmental factors. In combination, these qualities can be the true identity of oneself. Many people may argue that nurture appears to a play huge factor in the two, but others may think otherwise. Not having both as a characteristic can have a negative effect on a person physically and mentally. The debate of nature versus nurture appears to be the oldest argument known to man, and it still remains to be unanswered. In the old-age argument nature versus nurture, nature may play a huge role in determining a person’s true identity.

The nature vs nurture issue has been a controversial argument among psychologist for decades. This argument exposes two different views. One of them emphasizes that our personality depends solely on genetics (nature). On the other hand, the second view suggests that humans “develop through experience” (Myers 2013, SG 6) (nurture).

Identical twins may share the same DNA make up and grow up in the same household, yet they have very distinct personalities. On the other hand, twins that may have been separated at birth, find that years later when they meet up for the first time that they have very similar character traits and experiences. Researchers have been trying to figure out for years if DNA or environment has a bigger factor in determining a twin’s personality. When researchers try to determine how personalities are developed, they often look to twin studies to determine if DNA or life experiences are influential in personality development.

In reading stories about identical twins my point of view is easily understood. Various types of psychologist have analyzed the study of identical twins. It shows that individuals with the same genetic make-up can be totally different, when it comes to personality. Nurture promotes the twins to grow up as separate individuals. Its a lot better if a twin has his or her own personality rather than the same exact personality of the other half. I think this great debate weighs heavier on the nurture side. As a child my parents, and sibling overshadowed my genetic make-up. No matter how much I thought my physical traits made me behave. It did not affect me more than the things that I had seen and been exposed to. The more things that I had seen around and experienced made me the person that I am today. If my genetic make-up was totally different, to a certain extent, I am sure that I?d behave the same way that I do presently. There are exceptions to that. For instance if I were six foot five and one hundred and ninety pounds, I?d most likely be in the NBA and be really rich. I think if I was really rich and in the NBA I wouldn?t have the same worries that I have today. Even if before I were in the NBA I would have lots of attention and have a lot more confidence. So to an extent I would change a little if my genetic make-up were different. In a sense, genetic make-up is just a competitor to the environmental factors

This study included 361 families, each of whom adopted a child. Participants were the adoptive parents, the adopted child and the birth mother. One of the best studies to distinguish between what is caused by genetics and what is caused by environment is an adoption study, as there is a very distinct differentiation between nature and nurture. (Natsuaki, et al.)

Twin studies are a vitally important tool for dissecting the nature versus nurture argument. Twins provide a naturally occurring experiment and they are most likely the best indicator of determining whether biology effects traits and psychopathology in human beings. Researchers are seeking circumstances involving twins providing evidence of known variations in the extent of genetic similarity or environmental stability. The key factor in utilizing twin studies to determine biological basis for personality differences exist among identical twins and fraternal twins. These studies provide data among the individuals that are genetically identical but yet, display visible differences that may be attributed to environmental differences. Additionally, researchers used such studies involving

One of the oldest, most prominent topics of academic debate is the Nature vs. Nurture argument. Nature vs. Nurture is a largely psychological term, in which the Nature aspect places more significance on genetics and personality; our innate predisposition to various circumstances tell us a great deal more about who we are. On the other side, the Nurture aspect places more focus on our environment and stresses the salience of the majority of what we do in our daily lives have been “learned” We see a wide array of examples of this specific argument in literature, popular culture, and even in our everyday lives. While no one can deny that both sides have extremely valid points, it would be very naive to assume that one had more of a dominant factor;

These type of studies give an opportunity to investigate does environment impact twin’s personality despite the fact they have a same genetic relationship? Or does heredity impact their personality even though they are raised up in the dissimilar environment? In addition, identical twins share the same genetic information, therefore, researchers find it’s easy to figure out whether nurture plays a major or a minor role in a person’s

Who a person’s parents or relatives are is already predetermined at conception. The traits that a child’s family have are going to be his/her traits simply because of genetics. According to the above study done on Croatian twins, genetic factors account for “stability in personality” from seventy-five to one hundred percent (Bratko and Butkovic 155). The researchers used genetic models to look into the differences between twins. They broke genetics into two sources in this study: additive genetic influences and nonadditive genetic influences. Bratko and Butkovic insinuated that, based on the findings of this project, heredity was mostly attributed to the steadiness of personality in the pairs of twins. In the novel Nature Via Nurture: Genes, Experience, & What Makes Us Human by Matt Ridley, a quote was attributed to Ralph Greenspan from his research on romance between fruit flies. He likened personality to this

When brought up together, they often exhibit very similar traits. In one case where two identical twins were brought up apart, they still exhibited very similar traits (Powell), providing evidence that DNA is the main contributor to peoples’ personalities. Although there is evidence supporting the nature theory, many sociologists today believe that personality is developed through society one is placed in. For example, reaction to narcotics would be the same all over the world if DNA provided personality.

Clearly one can see that the book My evil twin is a great example about twins. Many twins have different kinds of behaviors because the majority of them do not come out the same. For example one twin brother may have an aggressive behavior and the other one could have a really mellow behavior it just depends on the person. Genetics could be the cause of different behavior as well, but not only genetics the environment could make a difference as well. The development of personality differences should be reflected in the brain.

Nature versus nurture can be a discussion that discusses the reasons why a person may behave a certain way or perform tasks in a certain manner. You can look at someone actions and compare them to their parents or close relatives. Were they born with distinct traits that caused actions similar to their relatives, or were there actions or behaviors learned from some type of influence or environmental situation that they were raised in? Nature versus nurture can be debated but, describes why we behave the way we do or respond to a situation in a certain way.
