Abstract
Two groups of rats received differential instrumental conditioning trials in a two-phase experiment. One group received discriminative S+/S- cues prior to making the instrumental response. Such cues were presented to the second group upon inception of the response. During Phase 1 large or small reward was present on all trials. During Phase 2 (S+ extinction) reward was present only in the S- (small reward) alternative. The results are seen as supportive of a frustration or inhibition interpretation. Discrepancies between the present and previous data are discussed.
