Abstract

In Experiment 1, rats exhibited polydipsia on a concurrent spaced-response, variable-ratio schedule of reinforcement for bar presses on two bars, indicating that even the availability of a reinforcement schedule (VR) that encourages high and steady bar-pressing rates does not eliminate the polydipsia induced by the spacing of food. In Experiment 2, rats developed polydipsia in response to a spaced-food schedule, even though every water lick delayed food delivery for 30–60 sec, indicating that the development of polydipsia does not depend on adventitious food reinforcement.
