Facilitation of schedule-induced behavior

Abstract

Sixteen food-deprived Norway rats were run on a standard schedule-induced polydipsia training schedule until drinking was stable. Subjects were then assigned randomly to receive a 5-day, 2-week, 4-week, or 10-week delay before reacquiring polydipsia. No differences were obtained for milliliter consumed during acquisition or reaquisition except for an increase in milliliter consumed for the 5-day delay group during reacquisition. The implications of this result are interpreted in light of expected results.
