Self-controlled feedback on a variety of tasks are well established as effective means of facilitating motor skill learning. This study assessed the effects of self-controlled feedback on the performance of a serial motor skill. The task was to learn the sequence of 18 movements that make up the Taekwondo Poomsae Taegeuk first, which is the first beginner's practice form learned in this martial art. Twenty-four novice female participants (M age=27.2 yr., SD=1.8) were divided into two groups. All participants performed 16 trials in 4 blocks of the acquisition phase and 20 hr. later, 8 trials in 2 blocks of the retention phase. The self-controlled feedback group had significantly higher performance compared to the yoked-feedback group with regard to acquisition and retention. The results of this study may contribute to the literature regarding feedback by extending the usefulness of self-controlled feedback for learning a serial skill.
在各种任务中，自我控制反馈作为促进运动技能学习的有效手段已得到充分证实。本研究评估了自我控制反馈对连续运动技能表现的影响。任务是首先学习构成跆拳道品势太极一章的18个动作的顺序，这是该武术中初学者学习的第一个练习形式。24名新手女性参与者（M年龄=27.2岁，标准差=1.8）被分为两组。所有参与者在习得阶段的4个组块中进行16次试验，20小时后，在保持阶段的2个组块中进行8次试验。在习得和保持方面，自我控制反馈组的表现明显高于匹配反馈组。本研究结果可能通过扩展自我控制反馈对学习连续技能的有用性，为有关反馈的文献做出贡献。
