Nature Vs Nurture : Nature V. Nurture

Table 3-1 examines the correlations between selected characteristics for the identical twins separated at birth and the twins raised together. When compared to each other, they both have very similar brain wave activity, blood pressure and heart rate in the physiological characteristics. The Raven intelligence test was very similar, but the WAIS IQ displayed a bit of difference when compared to the other comparisons made. Personality wise, they typically had similar personalities at the same rate as twins raised together. Psychological interests were off a little bit, but still very similar. The twins that were separated at birth had less similar psychological interests compared to the twins

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.

Twin studies are a mainstay of the nature verse nurture debate because they allow researchers to conduct “natural experiments” on human beings. When researchers try to determine the relative importance of genetics and environment with regard to a certain condition, they have a hard time because they cannot generally get people with the same genes. This is where twin studies come in. Twins studies are part of the method used in behaviour genetics, which includes all data that are genetically informative. E.g. siblings, adoptees, pedigree data etc. Researchers use this method to estimate the heritability of traits and to quantify the effect of a person 's shared environment (family) and unique environment (the individual events that shape a life) on a trait.

The Minnesota Twin Registry started in 1983 and its goal was to establish a registry of all twins born in Minnesota from 1936 to 1955 to be used for psychological research.., T.J. Bouchard, working in conjunction with the University of Minnesota, started exploring the similarities and differences in characteristics like personality, career interests, and a variety of personal interests between identical twins who were reared apart. Research was conducted on twins from all over the world. The Minnesota Twin study gave scientists a new insight of the role of nature vs. nurture on human development and personality; it was the hope that twin studies would be able to tie genes to specific behaviors. From the study, we understand that twins who were separated at birth and raised in different families

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

The nature- nurture debate has many different case studies, which often questions environmental and hereditary aspects of the nature- nurture debate. A tangent which is focused on in this essay is how the case studies of schizophrenia and IQ, specifically affect twin and adoption studies. This essay will firstly, give a brief outline of the nature-nurture debate and the definitions of twin and adoption studies. Secondly, it will illustrate two main case studies, which are IQ and Schizophrenia studies. Thirdly, will contrast and compare the two and research’s impact on the case studies in regards to nature vs. nurture and finally, will conclude with the impact of the nature-nurture debate and twin and adoption studies.

The main focus of this study is whether nature or nurture is stronger. The researches wanted to see if twins who were separated at birth would still grow up to be similar. I believe the results will be that the twins will share some interests and similarities, like all siblings do, but because of the separation they will not be as similar as that might have been if they had been kept together. From my experience, people are born with a personality. There are certain traits that we are born with that the environment we grown up in can influence, but cannot completely change. With that said, the environment we grow up in does play a large role in the people we become and what are opinions are. As we talked about with the sociological imagination, outside influences make a huge impact on our

According to Begley, identical twins are not always identical in behavior just because of genes. Some studies show that when twins are given different circumstances, for example, different educational opportunities, different results are obtained. One example in Newsweek showed one twin may grow to be a professional pianist while the other twin was not at all musical even though the twins were both raised in a musical environment ("Heredity" 69). Twins have different interest from each other, and express them in individual ways.

It is the popular saying that identical twins share much more than superficial physical characteristics that seems obvious and glaring both in nature and traits. Formed from a single egg that divides at an early point in gestation, identical twins have what may be the most intimate of all possible human relationships. They often are attracted to the way of life like same careers, enjoy the same style and type of music and same sports, like or dislike the same foods, pursue the same interests academically and recreationally, and find themselves aroused by similar emotional stimuli.

Throughout history, across all cultures, people have been fascinated with twins. In addition to interest in the close emotional ties and biological similarities that twins may share, reports of special twin languages and twin extrasensory perception (ESP) help people to explore ideas of what it means to be human. How similar or different are they to each other? How important are genes and environment for development? Because identical twins share all of their genes, it is the environment—rather than genetics—that accounts for any differences between them.

In society, not one person is alike. By saying this, many people believe that they strongly take after their parents. Meaning they think Nature is a big part in their life and why they are who they are. The genes in each cell in us humans determine the different traits that we have, more dominantly on the physical connections like eye color, hair color, ear size, height, and other traits. However, it is still not known whether the more abstract attributes like personality, intelligence, sexual orientation, likes and dislikes are gene-coded in our DNA. The nurture theory has experiments showing a child’s behavior with the environment as to adult behavior. In the Nature Vs Nurture debate, everyone has their own thoughts and ideas on each

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.

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)

Scientists and psychologists everywhere study twins. The argument most commonly studied is nature versus nurture. The focus of this essay, however, is whether or not to separate twins in schools. Some believe the separation is demeaning and traumatic to the twins. The side about to be proved however that is this separation is a necessary step in the individualization of twins. Often, separation sparks the path to individualization.

For years I have been fascinated by that mysterious quirk of nature called twins. In my family, there are several sets of identical twins, and I have always concentrated on their similarities. I did not realize that identical twins also have many differences. My identical twin cousins, Sue and Heidi, appear to be perfect mirror images. They love to dress alike. They can feel each other's pain. They sound alike and can complete each other's sentences. But upon taking a closer look, I have found that they are as different as day and night. Aside from Sue and Heidi's outward characteristics, they possess several distinguishing traits that allow them to be viewed as two separate, independent
