Prediction, control, and learned helplessness.

Examined the independent effects of perceived control over and perceived predictability of an aversive event on 100 undergraduates' performance on a memory task and depressive affect. All Ss completed the Multiple Affect Adjective Check List and the Desirability of Control Scale. Ss who received noise blasts that were both uncontrollable and unpredictable displayed performance decrements and depressive affect relative to a no-noise group, whereas Ss who were able either to control or to predict the aversive event did not. The perception of control or predictability concerning the aversive event was thus sufficient to mitigate learned helplessness, suggesting the functional equivalence of perceived control and predictability. Finally, results reveal that Ss high in the "desire for control over events" reacted to the aversive noise more than did Ss low in the desire for control.
