Professor David Wilder joined the Rutgers Psychology Department after completing his PhD in 1975 at the University of Wisconsin. His research and teaching interests encompass the application of social cognition to intergroup relations, relationship between time sense and consciousness, and the history of psychology. Most of his research has focused on the application of social cognition (mental construction of the social world) to an understanding of prejudice and stereotyping. Factors that he has studied include the effects of social categorization on identity and bias, tactics to reduce bias, context effects on the use of stereotypes, and the role of anxiety in mediating the impact of information about other groups. His underlying thesis has been that some bias is a virtually inevitable, albeit undesirable, outcome of the process by which we cognitively organize our social world in search of a positive self-identity.
