What is a twin study?
Twins study is a psychological study that focuses specifically on twins. These studies are used to explore the science of genetics of behavior, and several psychologists actually specialize in twin studies. Double studies are questioned by some scientists, especially when psychologists place great emphasis on the results of the twin study. Others argue that they are very valuable, although they are only used as a starting point for further scientific investigation.
The twins are unique because they share genetic material. In fact, identical twins are genetically identical, while fraternal twins share half of their genetic material. This allows people who are interested in studying the role of genes in the development of personality to control the circumstances of their studies a little more. As psychological studies about people may be ethically ambiguous, a study of twins is one way to explore the interplay of genetics and the environment in examining personality withoutwould exceed Ethical border.
In most cases, it follows studies of twins that grow up in the same household. Ideally, the study should compare other types of siblings growing up in the same household as the basis for comparison. When twins show more similarities than conventional siblings, these similarities are assumed to be genetic. Other twins studies focus on the twins, which at birth tolerated separation, such as the twins that were accepted, in another effort to look at the role of the environment.
Critics of two studies point out that many factors affect personality and that even established features of genetic personality are extremely complex. These properties include multiple gene interactions and may not be quite fair to evaluate a personality based on a study that can be influenced by other factors. For example, some people may be genetically incited to carry twosThe Čata that could distort such a study. Moreover, a study of twins assumes that twins are treated the same, so their environment is comparable, and this may not always be the case.
As is often the case with scientific research, the twin study is the subject of the debate. It is important to carefully analyze the results of any psychological study, because human psychology is very complex. For example, a twin study can make a mistake to turn correlations to a causal context, or it emphasizes outdated research methods. Even with obvious shortcomings, however, the twins are certainly interesting and the concept of the Twin study also laid the foundations for behavioral genetics.
