Essay on Nature vs Nurture Twin Studies and Adoption

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. â€Å"The term â€Å"nature†¦show more content†¦Extending on from these, factors in each layer are influenced by elements within and outside of their layers. For example what a child is exposed to as a result of his/her parent’s beliefs. (Social Issues Referencing, 2007) Due to these factors, the nature- nurture theory has impacted and influenced many studies, one of these being the twin and adoption case. Twins, share a bond that no parent, child or sibling relationship can ever compare. There are two main types of twins, and these include: monozygotic (identical) twins and dizygotic (fraternal) twins, and they are compared by their emotional, behavioural, and cognitive similarities. (Robert Plomin, 1997). According to Social Issues Referencing, 2007, whereas Identical twins are formed from a single (mono) zygote and are genetic â€Å"carbon copies†, fraternal twins develop from two (di) separate zygotes, as a result of two eggs being fertilized by two sperms independently. (Social Issues Referencing, 2007, para. 8) Ultimately adoption is â€Å"the legal process which permanently transfers all the legal rights and responsibilities of being a parent from the childs birth parents to the adoptive parents†, (Human Services, Community Services, 2009 p. 1) so parents who are not related to the child in any form are adopting the child. In a sense, Twin studies relates to nature, asShow MoreRelatedAdoption and Nature vs Nurture1028 Words   |  5 Pages They were all adopted.

In the nature versus nurture debate, the term nature refers to the genes we inherit while the term nurture refers to our outside environment (Nature vs. Nurture: Twin and Adoption Studies). This debate of ‘nature vs. nurture’ has existed for centuries and up to now it is still a topic of major discussion although at present time. Human development is the scientific study of age-related changes in behaviorRead MoreThe Importance of Nature and Nurture Essay1036 Words   |  5 Pages The nature versus nurture debate has lasted centuries due to the difficulty of separating genetic and environmental factors in humans. Studies on behavioral genetics measure similarity between subjects, but cannot locate its origin. For this, a control must be present, leading scientists to twin research. Identical twins have the exact same DNA, differing from fraternal twins with only 50% similarity, no greater than average siblings. Identical twins offer a natural experiment that allows researchersRead MoreEssay Genetic and Environmental Contributions to Substance Abuse1125 Words   |  5 Pagesquestion of nature vs. nurture has been the focus of many debates, especially within the discipline of psychological sciences.

The idea that people can receive behavioral traits from one’s parents is the study of behavior genetics. Early Genetics One of the first people to study heritability was Sir Francis Galton. He was inspired by his cousin, Charles Darwin. His research was based around how certain genes were either passed down, or influenced. He widely popularized the term nature vs nurture, which is often brought up alongside behavior genetics. Galton studied the â€Å"probability that the son of
