EFFECTS OF REWARD CONTINGENCY AND PERFORMANCE FEEDBACK ON INTRINSIC MOTIVATION

93 high school students were offered performance or task-contingent rewards or no reward for doing hidden-figures puzzles. Ss offered performance-contingent rewards all received positive feedback concerning performance, and half the Ss in task-contingent and no-reward conditions received the same positive feedback. Performance-contingent rewards were found to undermine intrinsic motivation more than task-contingent ones, which produced decrements relative to control conditions of no reward, supporting E. Deci's (1972, 1975) control model. Positive feedback enhanced intrinsic motivation; this effect was independent of reward effects. A recall measure indicated that Ss receiving performance-contingent rewards remembered fewer performance-irrelevant details about the task, suggesting that rewards may affect the process of task involvement as well as its motivational outcomes.
