POVERTY AND BEHAVIOR - ARE ENVIRONMENTAL MEASURES NATURE AND NURTURE

This article critiques the Child Development special issue on poverty. First, we argue that the special issue has understated the variation observed within social class groups. Second, we believe that a confoun ding of genetic and environmental effects in biological families weake ns the case for environmental effects as presented in the special issu e. Our conclusion is that behavior genetic research designs are requir ed for studies of poverty. (C) 1997 Academic Press.
