This study examined the facilitatory effect of goal setting in physical performance. Three potential mechanisms that may mediate this effect are described: increases in time spent practicing, promotion of effective training strategies, and increases in commitment resulting from public goal setting. Students (N=51) performed a novel task under one of three conditions: public goal setting, private goal setting, and no goal setting. Goals selected, time spent practicing, strategies used during practice, and actual performance were assessed. Subjects in the two goal-setting groups showed better performance than those in the control-group; those in the public goal-setting group spent the most time in practice, but this was not reflected in better performance. Test performance was predicted by baseline performance and by the goal set; practice time, training strategy, and public goal setting did not account for further variance in performance. Although this study failed to find a mediating effect for these three mechanisms, the results must be interpreted with caution.
