This experiment investigated how different percentages of incentive pay affected performance on a number-entering task. It was hypothesized that the critical factor in incentive pay systems was the absolute amount of money that could be earned in an incentive pay paradigm. A counterbalanced single-subject reversal design was employed to examine effects of incentives on performance. Twelve subjects were used in the experiment with three subjects assigned to one of four experimental paradigms. Two of the experimental paradigms incorporated 10% and 100% incentive pay conditions, while the other two experimental paradigms incorporated absolute pay conditions equal to the 10% and 100% incentive pay conditions. Results indicated that similar trends in productivity occurred across subjects in all four experimental paradigms.
