Inescapable Shock Increases Finickiness About Drinking Quinine-Adulterated Water In Rats., Clinton Chapman, Nancy Dess, Thomas Minor
Clinton D Chapman
Conducted 3 studies with 108 male rats to examine the effect of inescapable shock on finickiness, operationally defined as suppressed consumption of quinine-adulterated water. Exposure to a single session of inescapable shock increased finickiness relative to simple restraint or no treatment. The effect of shock on finickiness was replicable, was specific to adulterated water, and persisted for at least 24 hrs. The weak quinine solution rejected by shocked Ss supported a conditioned taste aversion, suggesting that the difference between shocked Ss and controls was not due to the inability of the latter to taste the quinine. It is suggested that …

Stressors In The Learned Helplessness Paradigm: Effects On Body Weight And Conditioned Taste Aversion In Rats., Clinton Chapman, Nancy Dess, John Garcia, Jeffrey Raizer

In Exp 1, 44 male rats drank saccharin or a control solution, followed by 100 inescapable shocks or simple restraint. Ss were weighed daily and were tested for saccharin aversion 2 days after the stress session. Shocked Ss gained less weight than restrained controls. Saccharin aversion was apparent only among Ss that had consumed saccharin before the stress session. In Exp 2, 72 Ss drank saccharin solution, followed by shock, restraint, or no treatment. Half of each group was injected with saline; the other half was injected with lithium chloride. Shock reduced body weight relative to restraint or no treatment …
