Effect of task-intrinsic rewards upon extrinsic and intrinsic motivation.

This report contains three (conceptual) replications of an experiment designed to test the relation between the magnitude of task intrinsic rewards and the degree of intrinsic and extrinsic motivation toward the task. Based on an attributional analysis of task motivation, it was hypothesized that (a) the degree of intrinsic motivation will vary as a positive function and (b) the degree of extrinsic motivation, as a negative function of task-intrinsi c rewards. Both predictions were supported within each of the separate replications. The discussion considered the theoretical and the practical significance of the findings.
