Wittenbaum and Moreland (2008) cite a study by Moreland, Hogg, and Hains (1994) about the decline of research in to small groups, in particular the lack of examination of the effects and psychology of group members.
I am looking for current research on the effects of small groups psychology and cognitive dissonance on group members.
Unfortunately, interest in studying social processes within small groups has diminished over time despite predictions of its resurgence.
Over half of the group-related research published from 1975 to 2006 involved intergroup relations (e.g., social identity, stereotyping), whereas other topic areas (i.e., group composition, structure, performance, conflict, and ecology) that involve intragroup processes were largely ignored. The implications of these trends for the fields of small groups and social psychology are discussed.
