Abstract
Predrinking or preloading different volumes of water or 0.9% saline reduced the rate of licking reinforced with 0.11 ml of water or 0.9% saline on a 1-min. VI schedule. Saline pretreatment always had less effect on the licking response than comparable volumes of water. These results replicate previous findings and confirm the utility of lick rate on a VI schedule as a measure of motivation and incentive value.
