Until recently, a handbook on neurosociology would have been viewed with skepticism by sociologists, who have long been protective of their disciplinary domain against perceived encroachment by biology. But a number of developments in the last decade or so have made sociologists more receptive to biological factors in sociology and social psychology. Much of this has been encouraged by the coeditors of this volume, David Franks and Jonathan Turner. This new interest has been increased by the explosion of research in neuroscience on brain functioning and brain-environment interaction (via new MRI technologies), with implications for social and psychological functioning. This handbook emphasizes the integration of perspectives within sociology as well as between fields in social neuroscience. For example, Franks represents a social constructionist position following from G.H. Mead's voluntaristic theory of the act while Turner is more social structural and positivistic. Furthermore, this handbook not only contains contributions from sociologists, but leading figures from the psychological perspective of social neuroscience.
