Repression-sensitization differences in recovery from learned helplessness.

The performance of repressors and sensitizers on a solvable anagram task was assessed after either a short delay (0 to 30 min) or a long delay (2 to 6 hr) following a standard learned helplessness induction. Results indicated that all subjects exposed to the learned helplessness induction exhibited performance deficits, compared with control subjects exposed to no induction. Furthermore, subjects who were tested after the short delay did not perform as well as subjects tested after a long delay. No difference in overall anagram performance was found between repressors and sensitizers. Consistent with theoretical predictions, however, the anagram performance of repressor subjects was significantly better in the long-delay than in the short-delay condition; this significant recovery effect between short- and long-delay conditions was not obtained for sensitizer subjects. Possible theoretical mechanisms for these effects and implications for future research are noted.

Persistence of learned helplessness in humans.

The duration of the effects of a common learned helplessness induction procedure, exposure to insoluble concept-formation problems, was assessed by varying the interval between the induction procedure and subsequent exposure to soluble anagrams. Participants tested immediately or 30 min after the induction procedure exhibited reliable helplessness deficits on all dependent measures. These effects, relative to the performance of a nonhelpless control group, were absent in subjects who experienced delays of 2 or 6 hr before anagram testing. The implications of these results for the development of more enduring helplessness effects and for the conducting of research into analogue intervention are discussed.
