Abstract

A two-choice discrete operant procedure was devised for the study of shock-correlated reinforcement effects in rats. In the presence of one auditory stimulus, responding on one response lever was reinforced with food; with another auditory stimulus, responding on a second lever was reinforced. It was found that discrimination performance of one group, relative to appropriate control groups, was facilitated when electric shock was correlated with reinforcement on one lever and not on the other. Further, relative discrimination levels were found to be higher on the lever correlated with the shock than on the alternate lever. The significance of the results for operant within-S studies and for a mediational theory of shock-correlated reinforcement was discussed.
