Overall, the Social Identity Theory and Health behavior research laboratory addresses both basic and applied questions with a broad focus on: 1) influence processes within and between groups; 2) the motivational role played by self-uncertainty in group behavior, intergroup relations, and self-conception; 3) the structure of self-conception and identity in group and intergroup contexts; 4) the role that group processes and intergroup relations play in attitudes and persuasion; 5) on physiological and biological processes related to group dynamics and attitude change; and 6) on health-related behaviors as the main outcome of most studies.

Current projects within the group processes and integroup relations domain include investigating how motivation to identify with a group (particularly from the uncertainty-identity theory point of view) leads to various individual- and group-level health behaviors, e.g., making risk-related health decisions to join a group. Other current and future research within this domain focuses on how the level of self-categorization (personal, interpersonal, or group) and social exclusion interact to impact people's risk taking, pro-social and anti-social behaviors, and physiological and biological arousal.

Current projects within the attitudes and persuasion domain include exploring how attitude ambivalence impacts physiological arousal (e.g., skin conductance, facial EMG, and heart rate) and biological arousal (cortisol and alpha amylase concentrations) and how providing social norms after ambivalence leads to changes in these physiological and biological responses. This research has culminated in a collaboration with a faculty members from the College of Media and Communication and the Department of Biological Sciences. Together, we have created and are testing a bio-psycho-social model of persuasive communication processing.
