The Contact Hypothesis has long been considered one of psychology’s most effective strategies for improving intergroup relations. In this article, we review the history of the development of the Contact Hypothesis, and then we examine recent developments in this area. Specifically, we consider the conditions that are required for successful contact to occur (e.g. cooperation), investigate basic psychological processes that may mediate the consequent reductions in bias (e.g. decreased intergroup anxiety, increased common group representations), and explore factors that can facilitate the generalization of the benefits of intergroup contact in terms of more positive attitudes toward the outgroup as a whole (e.g. increased group salience). We conclude by outlining the contents of the contributions to this Special Issue on Intergroup Contact, highlighting common themes, and identifying findings that suggest directions for future research.
