Children with developmental coordination disorder (DCD) struggle to learn new motor skills. It is unknown whether children with DCD learn motor skills more effectively with an external focus of attention (focusing on impact of movement on the environment) or an internal focus of attention (focusing on one's body movements) during implicit (unconscious) and explicit (conscious) motor learning.
This paper aims to determine the trends of implicit motor learning in children with DCD, and how focus of attention influences motor learning in children with DCD in comparison with typically developing children.
25 children, aged 8-12, with (n=12) and without (n=13) DCD were randomly assigned to receive instructions that focused attention externally or internally while completing a computer tracking task during acquisition, retention, and transfer phases. The motor task involved tracking both repeated and random patterns, with the repeated pattern indicative of implicit learning.
Children with DCD scored lower on the motor task in all three phases of the study, demonstrating poorer implicit learning. Furthermore, graphical data showed that for the children with DCD, there was no apparent difference between internal and external focus of attention during retention and transfer, while there was an advantage to the external focus of attention group for typically developing children.
Children with DCD demonstrate less accuracy than typically developing children in learning a motor task. Also, the effect of focus of attention on motor performance is different in children with DCD versus their typically developing counterparts during the three phases of motor learning.
Results may inform clinicians how to facilitate motor learning in children with DCD by incorporating explicit learning with either internal or external focus of attention within interventions.
患有发育性协调障碍(DCD)的儿童在学习新的运动技能方面存在困难。目前尚不清楚患有DCD的儿童在隐性(无意识)和显性(有意识)运动学习过程中,将注意力集中于外部(关注运动对环境的影响)还是内部(关注自身身体运动)时,学习运动技能的效果会更好。
本文旨在确定患有DCD的儿童隐性运动学习的趋势,以及与发育正常的儿童相比,注意力焦点如何影响患有DCD的儿童的运动学习。
25名8至12岁的儿童,其中12名患有DCD,13名发育正常,在获取、保留和转移阶段完成计算机跟踪任务时,被随机分配接受将注意力集中于外部或内部的指导。运动任务包括跟踪重复和随机模式,重复模式表示隐性学习。
在研究的所有三个阶段,患有DCD的儿童在运动任务上的得分较低,表明其隐性学习较差。此外,图形数据显示,对于患有DCD的儿童,在保留和转移阶段,内部和外部注意力焦点之间没有明显差异,而对于发育正常的儿童,外部注意力焦点组具有优势。
患有DCD的儿童在学习运动任务时的准确性低于发育正常的儿童。此外,在运动学习的三个阶段,患有DCD的儿童与发育正常的儿童相比,注意力焦点对运动表现的影响有所不同。
研究结果可为临床医生提供参考,指导他们如何在干预措施中通过将显性学习与内部或外部注意力焦点相结合,来促进患有DCD的儿童的运动学习。
