What Are the Neurological Foundations of Identities and Identity-Related Processes?: An Examination of How the Default Mode Network Relates to Identity Theory

Abstract

This chapter illustrates the relevance of neuroscience research on the default mode network to the identity theory research program. Specifically, we argue that the patterns of neuronal activity generated by the default mode network represent the referents of identity theory’s concepts. Further, we argue that research on the default mode network can supplement identity theory by offering the research program the ability to physiologically validate the existence of its concepts and processes, as well as elaborate in neurological terms their underlying causal mechanisms. Finally, we examine how an understanding of the neurological foundations of identity-related processes can expand identity theory into new domains of research.
