Abstract
The study was designed to test the hypothesis that "group members perceiving themselves as interdependent for their reward attainment become highly motivated toward the group task." Results generally are in accord with several predictions, one of which is that: "Members of groups who are instrumentally interdependent become more highly motivated toward the group task than Ss who can achieve their goals independently of the others in the group." Another prediction supported by results is that: "Under conditions of instrumental independence, Ss who are told that both they and their teammates can attain a valued goal through the group activity become more highly task motivated than Ss who are told either that only S or Ss partner can attain this goal."
