Abstract
Twelve food-deprived male albino rats, randomly assigned to three equal groups, were successively exposed to (a) baseline conditions with water freely available in both the experimental chamber and the home cage, and (b) baseline and free-reinforcement schedule (FFI-60-sec) conditions with water freely available in the experimental chamber and available on a free or limited basis in the home cage. Prior to experimental sessions, Group 1 had continuous access to water in the home cage, whereas Groups 2 and 3 were 12 and 22.33 h water deprived, respectively. Results indicated that water deprivation (a) increased the probability of the development of schedule-induced polydipsia, but (b) had no augmentative effect on either asymptotic intake level or rate of development of the phenomenon.
