Emergent patterns of feedback strategies in performing a closed motor skill

This study identified self-chosen patterns of feedback usage and how they i nfluenced accuracy and consistency in performing a closed motor skill. Lear ners completed 100 practice trials with 25 opportunities to receive knowled ge of results KR), the timing of which was self-chosen, followed by 25 no-K R retention trials. The study identified two patterns of self-chosen KR, na mely, a faded frequency pattern and a reversed faded frequency pattern. Ana lyses of variance indicated a significant trial block effect for accuracy i n acquisition and no significant main effects or interactions associated wi th self-chosen patterns of KR. Quantification of regularity of KR patterns yielded correlations indicating that less regularity was associated with gr eater accuracy in performing the task. These results were congruent with pr evious research on self-chosen feedback.
