Abstract

Five albino rats developed schedule-induced polydipsia when placed on a fixed-interval 90 second or fixed-time 90 second schedule of food reinforcement with water concurrently available on a fixed-ratio two. The imposition of 15 second and 30 second delay contingencies on water availability following pellet delivery failed to eliminate the schedule-induced polydipsia. Results are discussed in terms of two hypotheses previously proposed to account for the post-pellet nature of the schedule-induced polydipsic phenomenon.
