Effect of self- control feedback on the learning of throwing with one-hand

Since the factor of selecting and not the amount of choice feedback to the learner was the mechanism underlying motor learning in self-controlled context. The purpose of this study was to investigate the effect of self-control feedback on the learning of throwing with one-hand with use of yoked self-control group.
Forty five male students among university students of Shahid Beheshti University aged 18 to 28 years volunteered to participate in this study and were randomly divided into 3 groups: self-control group, traditional yoked group and yoked self-control group. Task was throwing sand bags with non-dominant hand. Taking the pretest , the subjects participated in acquisition phase (180 acquisition trails during 3 sessions, each took 3 blocks of 20 attempts) and 24 hours after the completion of the acquisition phase, the subjects took part in the retention tests and 5 min after the retention test, participated in the transfer. Data was analyzed by one-way ANOVA and Bonferroni post hoc test.
Results showed that all groups had significant improvements in acquisition phase. Moreover, according to the retention and transfer tests ' results, yoked self-control group had showed significantly more learning compared to self-control (p=0.001) and traditional yoked groups (p=0.001).
The results suggest that self-control condition have beneficial effects in motor skills learning. In addition, in learning motor skill, selecting the feedback received by the participants is more important than the number of received feedback.
