title: [Asymmetric effect of in-group social values on identity with common-identity and common-bond in-groups].
abstract: Moderating effects of group type on the relationship between in-group social values and group identity were investigated. Previous research has indicated that values attached to the in-group, such as its status, privileges, and power, lead to increased group identity. However, these studies have not investigated the role of the type of in-groups on this effect. We conducted an experiment that manipulated the in-group type. In the common-identity type of in-group condition, formation of in- and out-groups on the basis of social categorization was established. In the common-bond type of in-group condition, interactions between the group members were conducted. Results indicated that in the former condition, the degree of in-group social values affected group identity; however, this effect was not found in the latter condition. These results suggest that social values of the in-group have an asymmetric effect on group identity, depending upon the in-group type as a common-identity or common-bond group.
