This article evaluates the effects of two types of rewards (performance-contingent versus engagement-contingent) on self-regulation, intrinsic motivation and creativity. Forty-two undergraduate students were randomly assigned to three conditions; i.e. a performance-contingent reward group, an engagement-contingent reward group and a control group. Results provide little support for the negative effects of performance rewards on motivational components. However, they do indicate that participants in the engagement-contingent reward group and the control group achieved higher rated creativity than participants in the performance-contingent reward group. (...) Alternative explanations for this finding are discussed. (shrink)
