My research brings theories of group processes and emotion together to improve our understanding of group cohesion, loyalty, influence, and identity/identification. For the most part, I am interested in how individuals make decisions about their voluntary memberships in groups and the ramifications these decisions have on their (social) self-concepts. My recent work involves the use of vocal fundamental frequency (VFF) accommodation as an indicator of one’s internalized status beliefs and others’ collective validation of status claims.
