Type A behavior, need for control, and reactions to group participation

The present study examines the behavior of Type A coronary-prone subjects in group problem-solving sessions. Subjects discuss possible solutions to two problems in same-sex groups containing both Type As and Bs. As are much more likely than Bs to be seen as leaders and are rarely nominated as the least helpful member. Although A and B leaders are both seen as moderately likeable, A leaders' problem solutions are rated as lower in quality. Manipulations of problem importance and incentive for good solutions have similar effects on As and Bs. The results are discussed as being generally consistent with the proposal that Type As are primarily motivated by a need for control. Some indirect support is obtained for the idea that As are more susceptible than Bs to learned helplessness.
