Abstract

Rats got pellets on free-reinforcement (F) schedules with inter-pellet intervals from 30 to 480 sec. As the interval lengthened, drink frequency increased to a maximum and then decreased, average latency between pellet arrival and drinking increased, average drink duration increased, and licking rate within drinks decreased.
