• After an extradimensional shift from auditory successive discrimination to visual one where one of the original discriminative stimuli was continuously present (the incidental stimulus), retention of the original auditory discrimination was assessed. In Experiment 1, after the auditory discrimination in Phase 1, rats learned the visual discrimination in Phase 2 with one of the original auditory discriminative stimuli as the incidental stimulus. When they returned to the auditory discrimination in Phase 3, they immediately relearned the original discrimination but showed retardation in acquiring its reversal. In Experiment 2, rats received nondifferential reinforcement training on the visual stimuli in Phase 2 with one of the original auditory discriminative stimuli continuously present. They showed immediate relearning of the original discrimination in Phase 3. In Experiment 3, immediate relearning of the original discrimination and retarded tendency to acquire its reversal were comparable in Phase 3 whether after visual discrimination in Phase 2 with one of the original auditory discriminative stimuli as the incidental one or after simple maintenance in the home cages in Phase 2. These results were discussed in terms of transition in stimulus function between reinforcement prediction and occasion-setting.
