Abstract

Three rats were trained on DRL 30 sec. for food. All developed polydipsia. Two DRL extinction sessions were run, one with the dispenser click following each correctly-spaced response, one without it. Drinking continued through extinction sessions, at lower frequency. Two of the rats drank more in the extinction session with the click than in the one without it.
