Social influence in small groups: An interactive model of social identity formation

The present paper tries to overcome the dualism of group-level vs. individualistic analysis of small group processes, by presenting a model of social identity formation that incorporates factors at both levels of analysis as well as their interaction. On the basis of prior theorising in the social identity tradition and a programme of research spanning several interactive group research paradigms, we suggest that within small groups a social identity can operate as a contextual given, which shapes the behaviour of individuals within the group, as much as the behaviour of individuals within the group can shape social identity. This proposal is supported by a programme of research into social influence within small interactive groups. This research explores deductive (top-down) processes through which existing identities influence group processes, but also shows a reciprocal influence through which intragroup discussion creates a sense of group identity in the apparent absence of any direct intergroup comparison (an inductive, or bottom-up, path). It is the interaction between these two forces that we believe is characteristic of the way in which small groups achieve a sense of social identity. Supporting this view, we describe research that suggests that processes of identity formation play a key role in decision making, productive collaboration, consensualisation, integrative negotiations, and the development of shared cognition.
