Culture, Diversity, and Psychophysiology Lab

What We Study

In the CDP lab, we address these and related questions by examining cultural divides—i.e., when people's cultural norms are inconsistent with the prevailing norms of organizations and institutions.  

We use multiple methodologies, including laboratory-based experiments, internet-based surveys, field studies, and content analysis of cultural products. Our lab adopts a model of stress in which we differentiate "good stress" and "bad stress" using a combination of self-reported cognitions and emotions, overt behavior, and cardiovascular and hormonal reactivity. 

We examine the negative consequences of cultural divides and develop interventions aimed at bridging these divides and reducing opportunity gaps. Check out "Publications" to learn more about our recent work and "Contact Us" for an application to join the lab.

Who We Are

Principal Investigator


Sarah Townsend is an Associate Professor of Management and Organization. Her research focuses on how socially and culturally constructed beliefs shape (1) how people from different groups interact with each other and thrive (or flounder) within various organizational settings, and (2) how we can intervene to increase all people’s ability to succeed. Using a multi-method approach to examine stress and performance, she measures people's cardiovascular and hormonal responses along with their self-reported thoughts and emotions and their overt behavior.
