Psychobiology and social psychology: past, present, and future

Social psychology and psychobiology have a rich historical connection, although over the last half century these two disciplines have seemingly become estranged. To a significant extent, that alienation arose from an archaic and nonviable model of behavioral biology that retarded the development of both disciplines. With the emergence of modern biological perspectives, this impediment no longer limits fruitful collaborations among social psychologists and psychobiologists. Indeed, some of the most exciting contemporary developments are emerging from the areas of social neuroscience, cognitive neuroscience, and behavioral neuroscience. We review the history of links between social psychology and psychobiology, the factors that led to the segregation of these subdisciplines, and the modern biological perspectives that provide the basis for reintegration of these disciplines.
