Abstract
In Experiment 1 a decrease in incentive magnitude resulted in negative incentive contrast effects, which were a positive function of the amount of verbal reward reduction. In Experiment 2 an increase in amount of reward produced positive incentive contrast effects, which were, as in Experiment 1, a monotonic function of the amount of reward change.
