title: Contingency judgments by depressed college students: sadder but not always wiser.
abstract: We examined depressed and nondepressed college students' perceptions of control over outcomes in a task similar to the one introduced by Alloy and Abramson (1979, Experiment 2). In Experiment 1, when subjects completed a contingency learning task with no one else present, nondepressed subjects perceived themselves to have more control over frequently occurring response-independent outcomes than did depressed subjects, which replicated Alloy and Abramson's finding. When subjects completed the task in the presence of an observer, depressed students perceived themselves to have more control than did nondepressed students. In Experiment 2, the observer effects found in Experiment 1 were replicated, and we extended those results by showing that when response-independent outcomes occurred relatively infrequently, depressed and nondepressed subjects who completed the task in the presence of an observer did not reliably differ in their estimates of personal control. In Experiment 3, which included minor procedural variations from the other experiments, the pattern of results found in Experiments 1 and 2 was replicated under conditions in which observers were present while subjects received frequently occurring outcomes. Together, the results of the three experiments demonstrate that the consistently accurate personal control estimates of depressed subjects that have been found across a variety of situations break down when subjects complete a contingency learning task in the presence of an observer, and outcomes occur independently of response at a high frequency.
