Abstract

The purpose of this study is to investigate the beneficial effects of verbalizing acquired motor skill on motor learning. Eighteen young adults participated in this study. The participants were randomly assigned to two groups (the verbalizing group and the control group). First, the participants practiced two balls rotation task on the left hand for four minutes to familiarize themselves with the ball rotation task. Next, the participants’ ball rotation performance (the times of ball rotation and times of dropping it) was measured for one minute (Pre). Then, the verbalizing group talked about the motor skills acquired by the ball rotation practice. On the other hand, the control group read scientific magazine aloud for the same length of time as talking in the verbalizing group (i.e., two minutes). After the interventions, the participants’ rotation performance was measured immediately, after two minutes and one day after (Post 1, Post 2 and Post 3, respectively). The method of measurement was the same as in Pre measurement. Results showed that, the number of ball rotation was significantly increased in the verbalizing group, but not control group.Also, the improvement frequency of ball rotation in verbalizing group was significantly higher than that in the control group. Additionally, there was a significant relationship between the time for talking and the improvement frequency of ball rotation. On the other hand, frequency of ball drops was not obtained these effects. These results suggest that verbalizing of acquired motor skill has an advantage in terms of frequency of ball rotation which expresses motor smoothness, but not in terms of the frequency of dropping the ball which expresses motor error. And, the relationship also suggests that time length is important to lead the beneficial effects.
