Relinquishment of control and the type A behavior pattern: the role of performance evaluation.

We investigated the role of information processing in the control relinquishment decisions of Type As and Bs. Pairs of subjects worked independently on a task and received feedback indicating that their partner had performed at a comparable or superior level. On a second task, subjects combined their efforts and made decisions concerning who would work on different parts of that task. One third of the subjects made this decision before completing an evaluation of the initial performances. Another third completed the evaluation without knowing that they would subsequently make a control decision. The final third of the subjects completed their evaluations knowing that a control decision would follow. Results indicated that when the evaluations were completed last, or when the evaluations were completed first but without knowledge of the impending decision, Type As relinquished less control to a superior partner than did Type Bs. When the evaluations were completed with knowledge of an impending control decision, Type As and Bs did not differ in their decisions. These results suggest that under certain conditions, Type As use an automatic or mindless decision style with potentially maladaptive consequences.
