How feedback intervention affects the performance of self-efficacy:an eye movement study

Feedback intervention, especially the feedback valence, can affect people's working performance. And as an important mediator variable, self-efficacy has a great influence on the effect of feedback valence. In present study, people with different level of self-efficacy were selected as subjects. We gave feedback according to the valence, and compared subjects' performance and working efficiency. The present study used the eye movement tracing method to collect subjects' eye movement data, which were analyzed to show their processing. Results indicated that feedback is necessary to keep one's excellent performance stable. What's more, positive feedback is better to the subjects' performance and processing than negative feedback. Also, when self-efficacy was taken into account, results got more interesting. That is, people with low self-efficacy are more sensitive to negative feedback than the high ones, while the same result didn't show up when the feedback was positive.
