This experiment was designed to examine the reformulated theory of learned helplessness (Abramson, Seligman, & Teasdale, 1978) and the diathesis-stress model of depression (Metalsky, Abramson, Seligman, Semmel, & Peterson, 1982). Thirty depressed and 30 non-depressed students were divided into three groups (contingent, noncontingent, control). In the contingent group, subjects received controllable aversive noise. In the noncontingent group, subjects received uncontrollable aversive noise. In the control group, subjects did not receive any pre-treatment. Then three groups were exposed to seventy escape trials. The results partially supported the reformulated learned helplessness model. As the theory predicts, the pretreatment significantly impaired the performance of both depressed and nondepressed. On the other hand, contrary to the theory's prediction, depressed subjects did not show any significant impairment in their performance as compared with nondepressed subjects in the contingent and noncontingent group. And in the control group depressed subjects performed better than nondepressed subjects. These findings are inconsistent with diathesis-stress model which claims that only depressed subjects show helplessness when exposed to uncontrollable events.
