Effect of chlordiazepoxide on the partial reinforcement extinction effect.
Rats were trained to run in a straight alley under conditions of partial or continuous reinforcement. Extinction was slower after partial reinforcement. Chlordiazepoxide, administered during acquisition only, had no effect on acquisition but abolished the partial reinforcement extinction effect. The results support the hypothesis that chlordiazepoxide acts by attenuating the effects of averisive stimuli.
