Abstract
Two food-deprived female albino rats received 16% sucrose pellets under a fixed-time (FT) 60-sec food-reinforcement schedule, with water freely available in the test chamber. After water intake stabilized for each animal, subjects received either 6% or 32% sucrose pellets under the same FT 60-sec reinforcement schedule. This phase was followed by a replication of the initial 16% sucrose pellet condition for each animal. Water intake was found to decrease for each animal following an initial shift from 16% sucrose pellets to 0% or 32% sucrose pellets, but not following shifts from 0% or 32% sucrose pellets to 16% sucrose pellets. Adjunctive behaviors and shift-related elation-suppression effects were compared and discussed.
