GROUP COHESION Group cohesion was earlier described as the interpersonal attraction binding group members together. It enables a group to exercise effective control over its members in relation to its behavioral norms and standards. Goal conflict in a group, unpleasant experiences, and domination of a subgroup are among the threats to a group's cohesion. Groups with low levels of cohesion have greater difficulty exercising control over their members and enforcing their standards of behavior. A classic study of cohesiveness in 238 industrial work groups found cohesion to be an important factor influencing anxiety, tension, and productivity within the groups. Specifically, work-related tension and anxiety were lower in teams high in cohesion, and they were higher in teams low in cohesion, as depicted in Figure 9.2.
