Highly (23.5-hr.) as well as moderately (18-hr.) water-deprived animals preferred a location containing a 10% sucrose solution to one containing water after experiencing a series of forced-choice trials to each reward. Reliable incentive preferences were either eliminated or their development considerably retarded in highly water-deprived animals, however, when they experienced only sucrose at both positions prior to preference tests. These findings help explain discrepant results on the relationship of drive and incentive choice previously obtained in our laboratory from those in Beck's laboratory.
