Goal setting, achievement orientation, and intrinsic motivation: a mediational analysis.

This study investigated the interactive effects of achievement orientation and evaluative focus of assigned, task-specific goals on intrinsic motivation for an enjoyable pinball game. Regression analyses revealed that the effect of performance or mastery-focused goals on intrinsic motivation varied as a function of achievement orientation. Specifically, the provision of task-specific standards with a performance focus enhanced intrinsic motivation for achievement-oriented individuals, whereas the assignment of such goals proved deleterious to the intrinsic motivation of those low in achievement orientation. Individuals low in achievement orientation displayed the highest levels of intrinsic motivation when provided with mastery-focused goals. A similar pattern of effects was obtained on competence valuation and task involvement, both of which were additionally validated as mediators of the direct effects on intrinsic motivation.
