Schedule-Induced Polydipsia: The most extensively studied form of adjunctive behavior is the excessive intake of water (polydipsia) when rats are reinforced with food on a fixed-interval schedule. Schedule-induced polydipsia has been observed in a wide variety of fixed-interval schedules. Several factors contribute to the amount of schedule-induced polydipsia. First, the level of water intake increases as body weight decreases. Second, when the available fluid is preferred, the amount of polydipsia increases. Finally, the length of time between reinforcements and the level of polydipsia is described by an inverted U-shaped function
