Food intake was measured in rats after 10 food-deprivation periods ranging from 0 to 168 hr. in duration. Half the Ss in each deprivation condition had water available during the food-intake period; the other half did not. Results showed greater intake after the shorter deprivation periods for Ss without water and greater intake after the longer deprivation periods for Ss with water. These findings were discussed in terms of the limitations on intake imposed by stomach capacity and aversiveness of dry food.
