چرا انگیزه ذاتی پس از بازخورد منفی کاهش می یابد؟ نقش واسطه ای از خودپنداره توانایی و اعتدال آن با جهت گیری هدف

This study aimed to identify influencing factors that render students vulnerable to low intrinsic motivation. For this purpose, we investigated whether changes in students' ability self-concept after negative performance feedback affect their intrinsic motivation and whether this effect is moderated by achievement goals. In Experiment 1, 101 university students randomly received either negative or positive performance feedback after they had worked on a numerical test. As predicted, students' intrinsic motivation declined after negative feedback even if influences of actual performance were controlled. This effect was fully mediated by students' ability self-concept. Contrary to our expectations, the feedback effect on students' intrinsic motivation via ability self-concept was not moderated by their goal orientations. Experiment 2 (N = 90) replicated these findings and ruled out alternative explanations for the feedback effect such as general mood changes. Findings are discussed with regard to motivation theory and their implications for educational practice.
