Paper describes the role of reward schedule in regulation of food preference in rats. It has been shown that food seeking behavior in rats performing in di erent types of mazes is controlled by multiple-food-unit reward schedule related to change in attractive properties of reinforcement under food preference processing. The data obtained suggest that multiple-food-unit incentive effect revealed under studying of discrete reward paradigm of learning may be involved in a common mechanism underlying both food disorders and drugs addiction in humans.

Key words: food preference, multiple-food-unit incentive effect, motivation, rats
