Abstract
In this study we sought to determine whether mild depressives and nondepressives could respond adaptively and self‐correct their judgments of contingency when it was clearly advantageous to do so Ninety‐six undergraduates were given four contingency‐learning tasks involving pressing or not pressing a key to turn on a light and to judge the degree of control their responses had over light onset On the first task, which included a monetary contingency only on light onset, mild depressives were relatively accurate in their judgments of control Tasks 2 through 4, which also included a monetary contingency and feedback on accuracy of judgment of control, showed a Mood x Task interaction Mild depressives, but not nondepressives, became more accurate, and by the last task, mild depressives were more accurate than nondepressives Results were discussed in terms of incentive, feedback, and task exposure
