Relationship between Extrinsic Rewards and Intrinsic Motivation

Research on the effects of extrinsic rewards on intrinsic motivation suggests that in certain contexts the effect of task extrinsic incentives is to undermine subsequent interest in the task. Extrinsic rewards have also produced deleterious effects on the process of learning and quality of performance. Evidence concerning the variables which affect this interaction, such as contingency of reward, expectation of reward, threats of punishment, and positive feedback is reviewed. In, addition, the various dependent variables used in measurement of intrinsic motivation are compared and contrasted. Future directions for research are suggested.
