In keeping with the special issue theme of "Remembering the Future," this article provides a selective review of research on how memory for social information (i.e., social category representation) influences future processing and behavior. Specifically, the authors focus on how categorization and stereotyping affect how we perceive others and ourselves. The first part of the article reviews research on how individuals perceive others. The authors review research on the determinants and outcomes of social categorization and stereotype activation, concluding with the influence of ingroup/outgroup categorization on face processing. The second part of the article reviews research on how individuals perceive themselves. The authors argue that stereotype threat-concerns about being judged or behaving in ways that confirm negative group stereotypes, leading to poor performance-is the result of both self-categorization and stereotype activation. Overall, the article highlights the complex relationship between memory for social category information and future social perception and behavior. (C) 2012 Elsevier Inc. All rights reserved.
