Heredity-Environment Research and Development
Pages 11

Heredity has been primarily the domain of the biologist; the environment has been studied in a host of disciplines (geography, sociology, and so on). The consequence of this multidisciplinary situation is that, in focusing on heredity and environment, developmental psychologists for the most part select for explanatory research a set of independent variables or antecedents that they do not understand well. In addition, even for the biologist, geographer, sociologist, or social psychologist, the concepts of heredity and environment lack empirically precise definitions. The area of developmental genetics, therefore, is often clouded with misunderstandings and confused arguments, which, however, should not discourage further research.
