Tested a delay of gratification interpretation of the decrease in intrinsic motivation produced by expected, task-contingent rewards. In the task-contingent reward condition, 12 1st-3rd graders received an anticipated reward explicitly for undertaking the target activity in the E's absence. In the wait-contingent reward condition, 12 Ss received the same reward for awaiting the E's return rather than performing the interpolated activity. In the no-reward control condition, 12 Ss were neither promised nor given a reward. Intrinsic interest in the target activity was assessed during a subsequent free-play period. Contrary to the delay of gratification interpretation, Ss in the wait-contingent reward condition displayed significantly more interest in the activity than did Ss in the task-contingent reward condition. An individual difference measure of ability to delay gratification was not associated with intrinsic interest. Data are consistent with an attributional analysis of intrinsic motivation.
