There is increasing evidence that children with developmental coordination disorder (DCD) have deficits in sensory-motor integration, but it is unclear whether the sense of agency (SoA) generated by sensory-motor integration is altered.
To investigate whether there is a difference in the time window for SoA between children with DCD and typically developing (TD) children.
An agency attribution task was used to quantitatively measure and compare the time window for SoA in 15 children with DCD and 46 children in the TD group. Variables that correlated with the time window for SoA were also examined in both groups of children.
The time window for SoA was significantly extended in children with DCD compared to TD children. The time window for SoA in TD children was significantly associated with manual dexterity, whereas the time window for SoA in children with DCD was significantly associated with depressive tendency.
The time window for SoA is altered in children with DCD. The present results suggest that there may be a bidirectional relationship between an internal model deficit and depressive tendency and SoA in children with DCD.
越来越多的证据表明,发育性协调障碍(DCD)儿童在感觉运动整合方面存在缺陷,但尚不清楚感觉运动整合产生的主体感(SoA)是否发生改变。
探究 DCD 儿童与典型发育(TD)儿童之间的主体感(SoA)时间窗是否存在差异。
采用主体归因任务定量测量和比较 15 名 DCD 儿童和 46 名 TD 儿童的 SoA 时间窗。还在两组儿童中检查了与 SoA 时间窗相关的变量。
与 TD 儿童相比,DCD 儿童的 SoA 时间窗显著延长。TD 儿童的 SoA 时间窗与手灵巧度显著相关,而 DCD 儿童的 SoA 时间窗与抑郁倾向显著相关。
DCD 儿童的 SoA 时间窗发生改变。本研究结果表明,DCD 儿童的内部模型缺陷与抑郁倾向和 SoA 之间可能存在双向关系。
