Primary Reactions

In Experiment I rats were trained preoperatively on a successive, free-operant discrimination with fixed component durations until S— responding had been minimized. Septal damage resulted in a transitory loss of discriminative performance due to an elevation of S— responding. Experiment II showed a comparable septal deficit following training which employed a “correction” procedure that penalized S— responding. It is concluded that, even after extended training, the maintenance of a low level of S— responding by rats in these types of discriminations requires the operation of an active mechanism which can be disrupted by septal damage. The possibility that this disruption results from a lesion-induced change either in the primary reactions to frustrative non-reward or in associated processes is discussed.

Free Operant Situation

An experiment was performed to determine the extent to which the effects of continuous reinforcement, variable interval reinforcement, discrimination training, and discrimination reversal training would transfer between a vertical and a horizontal bar-pressing response in the free operant situation. No transfer of continuous or variable interval reinforcement was found. However, both discrimination training and discrimination reversal training showed very appreciable amounts of inter-response transfer. These results are discussed in terms of a mediational process involving classically conditioned mediators which exert discriminative control over overt responding.
