The motivational properties of schedule-induced polydipsia.
Schedule-induced polydipsia occurred during initial magazine training to Noyes pellets (45 mg), disappeared when lever-pressing was acquired on a continuous reinforcement schedule (CRF), and reappeared when the food contingency was changed to a 1-min variable interval schedule (VI 1 min). Polydipsia also developed under a VI 1 min food schedule when water was concurrently available on various f...
متن کاملEffects of drugs on the temporal distribution of schedule-induced polydipsia in rats.
Drinking was induced in food-deprived rats by a fixed-time 1-min schedule of food presentation. With three rats, d-amphetamine (0.25, 0.5, 1.0, and 2.0 mg/kg) led to a dose-related increase in licking early in the interfood intervals, the peak of the temporal distribution of licking being shifted to earlier values. These effects were seen even when d-amphetamine had no effect on overall rates o...
متن کاملEffects of Rat’s Licking Behavior on Cutaneous Wound Healing
Objective(s) Wound licking has been shown to advance wound healing among humans and many other animals. The present study evaluates the licking effects on healing of skin wound in rats. Materials and Methods Twenty four rats were assigned to 4 different groups randomly and two 3 cm longitudinal full thickness incisions were made on each dorsal and ventral side of rats. The ventral incisions ...
متن کاملEffects of d-amphetamine on temporal distributions of schedule-induced polydipsia.
Food-deprived rats were divided into four groups according to the equal interval and time durations of a multiple fixed-interval, fixed-time schedule (15, 30, 60, and 120 s). Fixed-time components were signaled by a tone and lever withdrawal. d-Amphetamine (0.25-4.0 mg/kg) produced similar dose-dependent reductions in the drinking and licking induced by fixed-interval and fixed-time schedules. ...
متن کاملSchedule-induced polydipsia in rats living in an operant environment.
The effect of variations in interreinforcement interval on the temporal and distributional relation between feeding and drinking was continuously monitored. Rats were housed continuously in an operant chamber in which water was freely available, but lever pressing was required to obtain food (45-mg pellets). Initially, pellets were delivered on a fixed-ratio 1 schedule of reinforcement, which w...
