THE PRENATAL ORIGINS OF BEHAVIORAL ORGANIZATION

Recognition that organisms have a developmental history, exhibit behavior that is uniquely suited to or constrained by features of their immediate environment, and adapt to new environments is central to current psychobiological thought. Unfortunately, these concepts have in the past been restricted largely to the study of postnatal behavioral development. However, recent extension of these concepts to the fetus as an active and interactive organism that resides within a specialized, intrauterine niche is proving to be a profitable approach toward understanding the origins of behavioral organization during development.
