Abstract: | Two experiments were conducted to examine the relationship between stress level and learned helplessness in human subjects. Experiment I subjected subjects to loud or moderate noise in order to induce differential stress. Half of the subjects within each stress group were unable to escape from a series of noise bursts, whereas the other half could terminate each burst by manipulating appropriate switches. After the pretreatment series, the same noise was again delivered to subjects, all of whom could now escape or avoid noise by making an appropriate response on a shuttle box. Inescapable (helplessness) pretreatment interfered with escape learning in the second (test) phase of the study under both levels of stress. Experiment II was a partial replication of the first study using only loud noise. The interference effect during test trials was greater than in the first study. In addition to these findings, measures of a coronary-prone behavior pattern were related to differential susceptibility to the interference effect under both high stress and moderate stress conditions. These results were interpreted in terms of differing perceptions of threat imposed by lack of environmental control. |
