Each day we are likely to interact with a variety of people, such as friends, relatives, and workmates, each of who has different thoughts and expectations. My research examines how participating in various interpersonal interactions shapes our self-understanding and evaluations of others, with a focus on outcomes related to ethnic and gender stereotyping, prejudice and discrimination. Even though stereotype relevant self-views and implicit prejudice are often thought to constitute stable, ingrained aspects of the self, my work shows that they spontaneously converge toward the perceived opinions of people with whom one wants to get along. I am also interested in the impact of contact with members of other ethnic groups, and one’s own ethnic group, on one’s degree of prejudice. Overall, my work suggests that interpersonal interactions are a vehicle by which cultural stereotypes and prejudices become individual thought.
