A functional perspective on group memberships: Differential need fulfillment in a group typology

The social motivation functions of intimacy, task, and social category groups were investigated. In two studies, participants were asked to consider the extent to which their group memberships fulfilled several needs. A factor analysis confirmed that the needs comprised three factors: affiliation, achievement, and identity. Intimacy groups were associated with affiliation needs, task groups were associated with achievement needs, and social category groups were associated with identity. A study using implicit measures reinforced those results, revealing the presence of the same implicit associations between group types and need fulfillments. A final study manipulated participants’ need state through a priming procedure. Priming a specific need (affiliation, achievement, and identity) led to an increased accessibility of the group type that was best suited to meet that need (intimacy, task, social category, respectively). Results help clarify the functional aspects of groups and have implications for the perception and organization of group-level information.
