John F. Dovidio, Ph.D. is the Carl Iver Hovland Professor of Psychology and Public Health at Yale University, and the director of the Intergroup Relations Lab. His work centers around issues of social power and social relations, both between groups and between individuals. He explores both conscious (explicit) and unconscious (implicit) influences on how people think about, feel about, and behave toward others based on group membership. He continues to conduct research on aversive racism, a contemporary subtle form of prejudice, and on techniques for reducing conscious and unconscious biases. His research further explores how the bias of health care providers and perceptions by members of traditionally disadvantaged groups of being stigmatized affects medical interactions, decisions, and outcomes.

CV

Andrea Vial is a doctoral candidate in social psychology working with Jack Dovidio and Victoria Brescoll (Yale School of Management). Andrea’s research focuses on the impact of gender identity, stereotyping, and bias on organizational behavior. She takes an interdisciplinary approach that combines basic experimental methods and classic social psychological theory with more applied organizational approaches to understand the many ways that gender can impact workplace relations and behaviors and career outcomes. For example, Andrea’s empirical and theoretical work has focused on (1) the experiences of women in high-power authority roles; (2) the overlap between gender stereotypes and leader role expectations; (3) gender in-group favoritism in leader-follower relations; and (4) the accommodation of gender-based third-party prejudice in hiring selections. Before Yale, Andrea received her BA in psychology with a minor in sociology from Hunter College (CUNY).

CV

April H. Bailey is a fourth-year doctoral student. Her work broadly investigates how people rely on another’s gender to make decisions about them. With a social cognitive focus, she studies the integration of gender and nonverbal behavior related to power during person perception. In this research she has used a variety of methods including: reaction time tasks, electroencephalogram, and recorded nonverbal behaviors. In another line of work, she investigates a subtle yet consequential form of gender bias called androcentrism whereby people think of men as representative of demographic-neutral categories. April collaborates primarily with professors Dr. Marianne LaFrance and Dr. Jack Dovidio.

CV
Bennett Callaghan is a third-year doctoral student. His research interests broadly relate to the psychology of social class, both in terms of how it is experienced (on a personal and cultural level) and how it is implicated in collective and inter-group process. For example, one current line of research investigates how class influences political participation and what kind of messages appeal to those of varying class backgrounds. Another one investigates the role of social class in propensities toward—and reactions to—prosocial behaviors, and a third examines class as a status-based entity that can be signaled to, and elicit particular behaviors from, others. He received his BA in Forensic Psychology, with a minor in English, at John Jay College of Criminal Justice (City University of New York) and spent two years at the University of Illinois at Urbana-Champaign before coming to Yale.

Natalie Markowitz Wittlin is a third-year doctoral student whose research focuses on psychological responses to members of gender minority groups.  In one line of work, for example, she employs methods from the study of gender essentialism to uncover implicit categorizations of transgender men and women.  In another, she investigates whether people who challenge widely-held assumptions about sex and gender are “dehumanized” - that is, denied traits thought to be unique to humans.  Natalie earned her B. A. from Barnard College at Columbia University with a major in psychology and a minor in political science.  Prior to beginning graduate school, she worked in the fields of education, public health, and psychology.

He is broadly interested in investigating the psychological factors shaping perceptions of, reactions to and motivations to address intergroup inequality across a number of societal domains (e.g., criminal justice, education, health). For example, one of his main lines of research examines how lay beliefs about the interpersonal or structural nature of racism shape subsequent responses, after exposure to racial disparities in the U.S. Criminal Justice System. Before coming to Yale, Julian received a BA in Psychology, with a minor in Sociology, at The University of Texas at Austin and received a MA in Psychology from Northwestern University.
