Parent Trap: A Psychological Analysis

The Parent Trap, a classic movie about two twin sisters who meet each other unexpectedly and try to push their divorced parents back into being one family again. While the story makes for an entertaining movie, does this phenomenon happen in real life? This movie and when I first learned about the value monozygotic twins had in the world psychology piqued my interest in this topic. How much can identical twins who have grown up apart from each other tell us about human nature and environmental impact? Beginning with the first pair of twins who started this line of research and going through several case studies, their findings, and also some critiques about the processes will be examined in this paper. In 1979, the media was buzzing with …show more content…

Through reading many publish case studies like the ones provided earlier, Joseph (2001) thinks that researchers need to publish more of their raw data instead of only providing summarized versions of their results. Withholding any kind of information in a study is definitely unethical in any field of research based science and taking steps to improve the availability of data is only going to be beneficial. In addition, there might be a more suitable control group alternative that is not being properly utilized in twin studies. Normally researchers use dizygotic twins as a point of comparison in the similarities found in monozygotic twins; however, there may be a reason to change. The replacement control group proposed is a completely biologically unrelated pair of strangers whose age, sex, ethnicity, socioeconomic status, cultural background, and appearance are similar (Joseph, 2001). This situation would be extremely similar to that of reared-apart monozygotic twins except for the fact that their biology is not a 100% match. Even after improving the methods of twin studies there is still the huge hurdle of finding a true pair of reared-apart twins. For example, some pairs might play down the true amount of time they were in contact with each other to seem more interesting, some twins knew about their lost pair, some may have …show more content…

MISTRA gave rise to the popularity of examining twins and has led to learning more about our relationship with genetics and the environment. However, the circumstances are not as clean as the movies want you to believe. Critics take on an important role when they can objectively take a step back and analyze the case for what it truly is while suggesting points of caution and areas that need improvements. Overall, there is still a need to continue these types of studies to determine the full extent of nature versus

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).

While Jose and Jorge are identical twins, their lives could not have been any more different. They have different health determinants to their unfortunate diseases that differ from each other. The case study of Jorge and Jose emphasizes the idea that your zip code determines your health more than your genetic code. Just a quick reminder, Jose is the twin who grew up in a largely improvised family, while Jorge is the twin who grew up in an upper-middle-class family. Since both brothers have asthma it can be assumed that the brothers have asthma in their genetics, however, needed to be triggered.

Ridley talks about facts and uses logic in regard of divorce rates in twins and criminal records of adoptees in Denmark. Closely observing that divorce rates in twins are partly supported by genetic variation and partly by non-shared environmental factors, it was concluded that, “You are no more likely to divorce if reared in a broken home than the average.” This shows that non-shared environment-- home and parents-- do not affect the person’s choices, characters or personalities but it is rather the environment consisting of peers along with genes that play a role. Similarly adoptees that have a criminal record usually diminish once adopted in a neighbourhood and going to school with non-criminal backgrounds and good morals even if biological and adopting parents have a criminal background. These two examples show strong reasons to support Ridley’s

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.

Designer babies, what are they exactly? Well, designer babies are human embryos that have been genetically modified, usually following guidelines set by the parent or scientist, to produce desirable traits. This is done using various methods, such as germline engineering or Preimplantation genetic diagnosis and is usually implanted using in vitro fertilization. Essentially, a designer baby is a baby made in a lab using an egg and sperm and then genetically modified based on what the parent wants. The embryo is then implanted into the uterus to grow as a normal baby.

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.
