Common Ingroup Identity, Perceived Similarity, and Communal Interracial Relationships

Integrating theory on interpersonal relationships and intergroup relations, this research examined the role of common ingroup recategorization (i.e., perceiving outgroup members as belonging to the same superordinate group as oneself) in fostering communal interracial relationships. A cross-sectional study (Study 1) and a short-term intensive longitudinal study (Study 2) involving Black and White friendship and romantic dyads suggested that recategorization predicted greater communal motivation and security via perceived similarity. These effects were found in terms of both enduring characteristics and changes over time. In turn, communal motivation and security predicted greater self-reported prosocial behavior and relationship satisfaction, suggesting that they are beneficial to interracial relationship quality. Communal motivation also predicted increases over time in recategorization and perceived similarity, suggesting bidirectional effects. Taken together, these results suggest a reciprocal process in which common ingroup recategorization and perceptions of similarity promote and derive from the communal nature of interracial relationships.
