Efectos de variar el nivel de privación de comida sobre el valor reforzante del agua en el beber inducido por el programa

Scheduled-induced drinking (SID) occurs when food-deprived rats are exposed to intermittent schedules of food reinforcement. In recent years, SID has been considered as operant behavior reinforced directly by water and it suggested that deprivation may function a motivating operation increases the reinforcing value water. The purpose study was determine effects varying food-deprivation levels on efficacy during sessions. successive phases, three were maintained at their free-feeding weights, or deprived 90 80% weights.
