Abstract
Performance feedback consist of providing information about past performance and indicating how to improve future performance. Previous research involving computerized tasks have shown that inaccurate feedback can delay or impede skill acquisition. Typically, those studies only assessed the effects of inaccurate feedback when acquiring new skills, and not how inaccurate feedback affects previously mastered skills. The purpose of this study was to investigate the effects of varying levels of feedback accuracy following skill mastery when completing a computerized match-to-sample task. Participants completed 250 initial trials with 100% accurate feedback, followed by an additional 250 trials with varying levels of feedback (20%, 40%, 60%, and 80%). Data show the mean number of correct responses per condition during the additional 250 trials decrease as the proportion of trials with inaccurate feedback increases.
