Psychobiological studies of stress and coping: an introduction.

Developmental psychobiology is the study of how the interplay between behavioral and physiological processes supports and directs development. This symposium section is devoted to work in this interdisciplinary domain focused on examining stress and how young organisms cope with and are affected by stressful experiences. In this introduction to the symposium section, the problems of interpreting and integrating information on stress reactivity derived from a combination of behavioral and physiological measures are discussed.
