It is in an attempt to synthesize such potentially disparate approaches to human development into an integrated whole that we undertake this series on the genesis of behav ior.
The need exists to provide, on an ongoing basis, an arena of discourse within which the threads of continuity between those diverse lines of research on human development can be woven into a fabric of meaning and understanding. How are we to understand the complex forces that shape human be havior? A variety of diverse perspectives, drawing on studies of human behavioral ontogeny, as well as humanity's evolutionary heritage, seem to provide the best likelihood of success. Each requires the opportunity to see-to the degree that our knowledge in given areas permits-various aspects of development in a coherent, integrated fash ion. It is hoped that this series-which will bring together research on infant biology, developing infant capacities, animal models, the impact of social, cultural, and familial forces on development, and the distorted products of such forces under certain circumstances-will serve these important social and scientific needs.
