The relation between academic race stereotype endorsement and academic self-concept was examined in two studies of seventh- and eighth-grade African Americans. Based on expectancy-value theory, the authors hypothesized that academic race stereotype endorsement would be negatively related to self-perceptions. Furthermore, it was anticipated that the relation between stereotype endorsement and self-perceptions would be moderated by racial centrality. The hypothesis was supported in two independent samples. Among students with high racial centrality, endorsement of traditional race stereotypes was linked to lower self-perceptions of academic competence. The stereotype/self-concept relation was nonsignificant among youth for whom race was less central to their identities. These results confirm the supposition of expectancy-value theory and illustrate the interweaving of group and individual identity with motivational beliefs. (Contains 6 tables and 2 figures.)
