Seventy-two Ss were tested in an escape/avoidance task in which omission of entertaining material served as the aversive stimulus event. Prior to these trials, Ss received 0, 15, or 30 escapable trials and either 0 or 100 inescapable trials with the same aversive stimulus. The results indicated that inescapable trials interfered with performance on the escape/avoidance task and that escapable trials negated the interference effect. The pretraining conditions more directly affected escape rather than avoidance performance. |
