Biosocial Research Contributions to Family Processes and Problems, based on the 17th annual National Symposium on Family Issues, examines biosocial models and processes in the context of the family. Research on both biological and social/environmental influences on behavior, health, and development is represented, including behavioral endocrinology, behavior genetics, neuroscience, evolutionary psychology, sociology, demography, anthropology, economics, and psychology. The authors consider physiological and social environmental influences on parenting and early childhood development, followed by adolescent adjustment, and family formation. Also, factors that influence how families adapt to social inequalities are examined.
