Helplessness Hypothesis

This study examined the effects of the opportunity to aggress during pretraining for learned helplessness. While rats individually given inescapable shock showed deficits in subsequent chain-pull escape, the performance of rats given inescapable shock in pairs did not differ from that of animals exposed to escapable shock or no shock. These results are interpreted as contrary to the prediction of the learned-helplessness hypothesis and are consistent with the notion that shock-induced aggression serves an adaptive function.

Starting Speed

Rats were exposed to 23½ hr. of either lever-press escape (Group E), yoked-inescapable shock (Group I), or a nonshock condition (Group NS). 24 hr. after the end of the preceding treatment all Ss received 25 massed trials of instrumental escape in a runway. Running speed for the E and I groups was significantly slower than that of the NS group during the last 20 trials. Starting speed was slower for the E and I groups only on the last block of five trials. These findings were discussed in terms of the recent work on learned helplessness.

Goldfish Carassius Auratus

7 groups ( N = 10) of goldfish, Carassius auratus, were treated with either prior or interpolated unsignaled-inescapable shocks or escape training (i.e., CS-omission) to assess the effects on subsequent avoidance performance. Both prior and interpolated inescapable shock exposures interfered with avoidance performance. Only the prior CS-omission training condition resulted in a similar effect. The relevance of these results to an interpretation of learned helplessness is discussed.
