| Abstract: | Reviews recent theoretical formulations on explaining and predicting the effects of reinforcement on intrinsic motivation. Included are the overjustification hypothesis of M. R. Lepper et al (see record 1974-10498-001), cognitive evaluation theory of E. L. Deci and R. M. Ryan (1975, 1980), the competing response hypothesis of S. Reiss and L. W. Sushinsky (see record 1975-28914-001), and the delay of gratification hypothesis of W. Mischel et al (see record 1972-20631-001). Cognitive evaluation theory was found to provide the most complete theory in that it generates predictions of both decreases and increases in intrinsic motivation. Little conceptual evidence was found for the major theoretical formulations, and the use of an interactional paradigm in future research is stressed.
