The impacts of acquisition and extinction cues on ABC renewal of voluntary behaviors

In two instrumental conditioning experiments with rats, we examined the impacts of acquisition and extinction cues on ABC renewal of instrumental behavior. Animals were reinforced with food for lever pressing in one context, followed by extinction of the response in a second one. Presentations of a brief tone accompanied extinction in Experiment 1 (extinction cue), and acquisition in Experiment 2 (acquisition cue). A final test in a third context revealed that instrumental responding was decreased in the presence of the extinction cue, whereas it was increased in the presence of the acquisition cue. We discuss theoretical and clinical implications of our results.
