Abstract
Eighteen Charles River (cd) male rats were conditioned to drink water polydipsically by the delivery of food pellets on FFI 45 sec, and then, varying percentages of sweetened nonnutritive pellets were substituted for the nutritive pellets. The mean volume of water ingested decreased with decreased nutritive content of the pellets, suggesting a relationship between schedule-induced polydipsia in the rat and the nutritive content of the reinforcer.
