Abstract

The purpose of this study was to determine if high and low activity individuals differed in terms of the effects of self-controlled feedback on the performance and learning of a movement skill. The task consisted of a blindfolded beanbag toss using the non-preferred arm. Participants were pre-screened according to their physical activity level using the International Physical Activity Questionnaire. An equal number of high activity (HA) and low activity (LA) participants were assigned to self-control (SC) and yoked (YK) feedback conditions, creating four groups: Self-Control-High Activity; Self-Control-Low Activity; Yoked-High Activity; and Yoked-Low Activity. SC condition participants were provided feedback whenever they requested it, while YK condition participants received feedback according to a schedule created by their SC counterpart. Results indicated that the SC condition was more accurate than the YK condition during acquisition and transfer phases, and the HA condition was more accurate than the LA condition during all phases of the experiment. A post-training questionnaire indicated that participants in the SC condition asked for feedback mostly after what they perceived to be "good" trials; those in the YK condition indicated that they would have preferred to receive feedback after "good" trials. This study provided further support for the advantages of self-controlled feedback when learning motor skills, additionally showing benefits for both active and less active individuals. The results suggested that the provision of self-controlled feedback to less active learners may be a potential avenue to teaching motor skills necessary to engage in greater amounts of physical activity.

摘要

本研究的目的是确定高活动水平和低活动水平的个体在自我控制反馈对运动技能表现和学习的影响方面是否存在差异。任务包括蒙上眼睛用非优势手臂投掷豆袋。使用国际体力活动问卷根据参与者的体力活动水平进行预筛选。将数量相等的高活动水平(HA)和低活动水平(LA)参与者分配到自我控制(SC)和匹配(YK)反馈条件下,形成四组:自我控制 - 高活动水平;自我控制 - 低活动水平;匹配 - 高活动水平;和匹配 - 低活动水平。SC条件下的参与者在他们要求时会得到反馈,而YK条件下的参与者则根据其SC对应者制定的时间表接收反馈。结果表明,在习得和迁移阶段,SC条件比YK条件更准确,并且在实验的所有阶段,HA条件比LA条件更准确。一份训练后问卷表明,SC条件下的参与者大多在他们认为是“好”的试验后要求反馈;YK条件下的参与者表示他们更希望在“好”的试验后得到反馈。本研究为学习运动技能时自我控制反馈的优势提供了进一步支持,此外还表明对活跃和不太活跃的个体都有好处。结果表明,向不太活跃的学习者提供自我控制反馈可能是教授参与更多体力活动所需运动技能的一个潜在途径。
