Subjective Judgments in Motor Learning

We investigated the relationship between the performance of motor learning and subjective judgment. [Subjects Twenty-six healthy young adults participated in this study. We divided participants into an improvement group (n=6) and a no improvement group (n=5). [Methods Participants were required to reach for a target key on a 49 piece keyboard without vision, and visual feedback was given 1 sec after push of the key. They performed 10 blocks (20 trials in each block). The success ratio was calculated for each block. Judgment of learning (JOL) as a prediction of performance of the next block was measured before each block. [Results In all the participant's results, a significant difference was observed between the success ratio and JOL, and there was no significant change in the accuracy of judgment through the blocks. In the groups, there was a significant difference between the success ratio and JOL in both groups, no significant difference of JOL between the groups, and there was no significant change of the accuracy of judgment through the blocks. [Conclusion The results suggest that there is no relation between the performance of motor learning and the subjective judgment of healthy young adults.
