Sharon George Dr. Zuckoff Fall 2014 Semester 28 November 2014 Sources of Human Psychological Differences: The Minnesota Study of Twins Reared Apart The study began in 1979, and over 100 pairs of twins or triplets who were reared-apart from across the United States, United Kingdom, Australia, Canada, China, New Zealand, Sweden and West Germany have participated. The conclusion of the study inferred two statements on the psychological behavioral variation between the subjects. The first was that genetic factors had a large amount of influence on the variation of behavior, and the second concluded that the being raised in the same home had little effect on behavior. This suggests that twins reared apart have an equal chance of being alike, the word alike being defined as personality …show more content…

The similarity between separated twins is found within personality, temperament, mannerisms, personal preferences, and perceived social behavior. There were no defining similarities between twins and their IQ scores. The causes of the similarities between the identical twins were explained by three points. The first was that intelligence is strongly influenced by genetics, indicating that in a Western standardized, middle class upbringing; the general variant of IQ can be attributed to genetics. The second point stated that modernized Western culture does not put constraints on the curation of individual psychological differences. This shows that a societies culture does not inhibit the growth on individual peculiarities, more specifically, the effect of parenting culture on a child. The findings show that parents often do not majorly influence psychological traits. The third point concluded that identical twins were so psychologically identical because of their genetics, that their environments were probably tailored in a similar way.

In the afterword the author talks about some of the speculations people have as to why Wes 1 and Wes 2 ended up so different. Naturally, the question of genetics and nature always comes up as an explanation for the defining difference between the two Wes Moores. On the other hand, certain points in the nature/upbringing of the two Wes Moores, such as Wes 2’s parents neglecting birth control, were speculated as the defining reason for the outcomes of the two Wes Moores. The author emphasizes that all these factors are actually woven together (Moore, 183). Similarly, the concepts of nature and nurture are closely meshed in the field of psychology (Textbook, 73).

In chapter eleven, “Paired and Pared”, of The Sibling Effect, author Jeffrey Kluger informs his audience about twins and only children and how they are different than other broods. Not only are twins and only children, referred to as “singletons,” biologically different, but their emotional, physical, psychological, and social development is as well. By devoting an entire chapter solely to twins and singletons, Kluger is indirectly claiming that these offspring view the world in a special, and sometimes unexplainable, way. Kluger validates this claim by the use of governmental policies, psychological studies, controversial viewpoints, and personal narratives. Kluger opens up the chapter by summarizing the harsh views of psychologists G. Stanley Hall and Abraham Arden Brill.

“that is why people usually just call one of us peace most of the time” Another thing that usually bothers a twin is being compared to one another. even though twins are almost the same person, it does not mean that they have the same personality. both twins agree that grades and sports are the biggest thing they get compared to each other with. from friends to family they are always being compared to each other by somebody. even though are some negatives about being a twin there are more positives to it than negatives.

it’s ok, we’re not angry.’” (Benway 355). My topic of inquiry relates the effects of both genetics and upbringing on childhood development. This quote shows the correlation that parenting styles do affect how a child's personality develops, and genetics are not the only factor in personality development.

However, this model is neglectful of conjoined twins’ capabilities to live a fulfilling life. Conjoined twins are two separate people that happen to share the same body, and are equally subject to the limitations that non-conjoined people face. Furthermore, unnecessary separation may be mental and physically detrimental for one or both twins. Generally, separation is harmful, close-minded, and denies the proven ability of conjoined

Dr. Rettew connects to class discussions and readings on shared and unshared environmental influences, evocative gene environment correlation, temperament, and the goodness-of-fit. Twins that with unshared environmental influences, such as different placentas, could adapt different temperaments (Berk, 2009). Also, twins that have been adopted into separate families could have different personality traits because they lived in completely different environments their whole life, even if they shared environmental influences of the same placenta (Berk, 2009). With an evocative gene environment correlation, a child’s genotype could draw in a certain type of environment, such as babies who appear more attractive will receive more attention (Berk, 2009). The type of attention a child gets could affect its temperament.

These two systems can be directly linked to the personality map developed by Eysenck, thus adding to the vast spectrum of personality traits. Nonetheless the intertwining of the Trait Approach and the Biological has moved the research of personality in to more exciting and new directions, technical advances have allowed more in-depth research into twin studies. For instance Peter Borkenau et al (2006) experimented on 168 identical and 132 fraternal

Stereotypes abound when it comes to birth order. The older sibling is said to be smarter and more responsible, the middle sibling is known as the attention seeker, and the youngest sibling is often the “spoiled one.” While these labels have been around forever, is there any research that supports these claims? Do these labels fit at all in your modern everyday family? In his article “The Power of Birth Order,” Jeffrey Kluger presents evidence and findings that does indeed substantiate most of the above-mentioned preconceived notions.

They are Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness (Maltby, Day & Macaskill, 2013). In order to highlight genes being prevalent in personality development, twin studies are compared. Monozygotic (MZ) twins are identical twins which share 100% of their genetic makeup while dizygotic

The Birth Order Effect Many scientists and psychologists believe that the chronological order of births in a family can influence each person’s personality, due to the environment they are raised in. The birth order theory divides the children in the family as being first born, the middle child, last born, and an only child, and each of these categories has many character traits established. For example, middle children are usually considered to be good negotiators because they have dealt with the oldest and youngest siblings fighting all of their life. This study also has its exceptions.

Studies show that nurture is more responsible for the way you act. Nurture dictates how you respond to others. It is true that many identical twins are a lot alike, but people don’t notice the differences between them. For example, the Jim twins were a lot alike, but I think that is just a coincidence. Anais and Sam both had the same laugh, but they also had different jobs.
