Six experiments examined the rat's preference for flavors associated with hydrolysed starch (Polycose) solutions. Hungry rats developed a preference for a flavor (CS+) mixed into a saccharin-sweetened 16% Polycose solution over a flavor (CS-) mixed in saccharin-water. The addition of acarbose, a drug which inhibits starch digestion, to the Polycose solution(More)
The present series of experiments examined the rat's conditioned preference for flavors associated with intragastric (IG) Polycose infusions. Adult female rats were fitted with two chronic intragastric catheters and were trained to drink flavored water (CS+; e.g., cherry-water) paired with IG infusions of 32% Polycose. On alternate days a different flavor(More)
Two experiments examined the rat's preference for flavors associated with nutritive corn oil and non-nutritive mineral oil emulsions. In Experiment 1 food deprived rats developed a preference for a flavor mixed into a 7.1% corn oil emulsion over a flavor presented in water. A significant but weaker preference was obtained for a flavor mixed into a 7.1%(More)
