| Abstract: | Three experiments with 296 undergraduates examined depressed and nondepressed (Beck Depression Inventory) Ss' perceptions of control over outcomes in a task similar to the one introduced by L. B. Alloy and L. Y. Abramson (see record 1981-02686-001). In Exp I, when Ss completed a contingency learning task with no one else present, nondepressed Ss perceived themselves to have more control over frequently occurring response-independent outcomes than did depressed Ss, which replicated Alloy and Abramson's finding. When Ss completed the task in the presence of an observer, depressed students perceived themselves to have more control than did nondepressed Ss. In Exp II, the observer effects found in Exp I were replicated; the present authors also showed that, when response-independent outcomes occurred relatively infrequently, depressed and nondepressed Ss who completed the task in the presence of an observer did not reliably differ in their estimates of personal control. In Exp III, the pattern of results found in Exps I and II was replicated under conditions in which observers were present while Ss received frequently occurring outcomes. Overall findings demonstrate that the consistently accurate personal control estimates of depressed Ss that have been found across a variety of situations break down when Ss complete a contingency learning task in the presence of an observer, and outcomes occur independently of response at a high frequency.
