根据Deci和Ryan（1985）的自我决定理论，自我决定的感知会调节感知能力对内在动机的影响，感知能力只在一定的自我决定条件下对内在动机产生积极影响。Vallerand（1997）的内在和外在动机的层次模型表明，自我决定和能力只对内在动机有独立的影响。本研究的目的是测试这些竞争模型。女性健美操参与者（n = 146）完成的措施，自我决定，感知能力和内在动机的锻炼。适度分层回归显示自我决定和感知能力的显着交互作用。然而，在高和低自我决定的条件下，内在动机对感知能力的回归图显示，这种互动并没有采取预期的形式。只有在低自我决定的条件下，感知能力的变化对内在动机产生积极影响。这表明，培养自决能力低的个人的能力观念尤为重要。
According to Deci and Ryan's (1985) self-determination theory, perceptions of self-determination moderate the effects of perceived competence on intrinsic motivation, with perceived competence only positively influencing intrinsic motivation under conditions of some self-determination. Vallerand's (1997) hierarchical model of intrinsic and extrinsic motivation suggests that self-determination and competence have only independent effects on intrinsic motivation. The aim of this study was to test these competing models. Women aerobics participants (n = 146) completed measures of self-determination, perceived competence, and intrinsic motivation for exercise. Moderated hierarchical regression revealed a significant interactive effect of self-determination and perceived competence. A plot of the regression of intrinsic motivation on perceived competence under conditions of high and low self-determination, however, showed that the interaction did not take the expected form. Variations in perceived competence positively influenced intrinsic motivation only under conditions of low self-determination. This suggests that it is particularly important to foster perceptions of competence among individuals low in self-determination.
