Strength of identification and intergroup differentiation: the influence of group norms

The present study aimed at showing that the relationship between identification and ingroup bias is moderated by salient group norms that prescribe or proscribe differentiation in an intergroup context. A study (N=191) in which level of identification and group norms were manipulated showed that high identifiers acted more in accordance with a salient differentiation norm compared to low identifiers. When a fairness norm was made salient, however, the expected difference was not obtained. The results are discussed in the context of the inconsistent relationships between ingroup bias and identification found in previous research. ©1997 John Wiley & Sons, Ltd.
