Abstract:

Genetically informed design, such as twin and adoption studies, help delineate mechanisms of social influence on individual differences in a wide range of psychological characteristics. This paper reviews findings from the Nonshared Environment of Adolescent Development (NEAD) study and its contribution to our understanding of environmental mechanisms for adolescent development, with special attention to child effect on family systems. Future directions for quantitative behavior genetics research are discussed

Key words: twin and adoption designs, child effect, social mechanisms for genetic expression
