Thomas J. Bouchard Jr. (born October 3, 1937) is an American psychologist known for his behavioral genetics studies of twins raised apart. He is professor emeritus of psychology and director of the Minnesota Center for Twin and Adoption Research at the University of Minnesota.
The Minnesota Center for Twin and Family Research (MCTFR) is a series of behavioral genetic longitudinal studies of families with twin or adoptive offspring conducted by researchers at the University of Minnesota. [1] It seeks to identify and characterize the genetic and environmental influences on the development of psychological traits.
The Twins Early Development Study (TEDS) is an ongoing longitudinal twin study based at King's College London.The main goal of TEDS is to use behavioural genetic methods to find out how nature and nurture (environments) can explain why people differ with respect to their cognitive abilities, learning abilities and behaviours.
[1] [2] Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, [3] [4] and in the case of intelligence at least 500 genes. [5] Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors.
Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes , and disorders. Twin research is considered a key tool in behavioral genetics and in related fields, from biology to psychology.
The study revealed that intellectual development was heavily influenced by genetic ability, especially among more advantaged children. It also showed that on average, black children demonstrated less genetic and more environmental influence on their intelligence than white children.
The journal covers research on the biology and epidemiology of twinning as well as biomedical and behavioral twin- and molecular-genetic research. According to the Journal Citation Reports, it has a 2018 impact factor of 1.159. [1] The journal was established in 1998 and has been edited by Robert Derom (1998–1999), and Nick Martin (2000
