目的.先前的研究表明，患有发展性协调障碍（DCD）的儿童在分配注意力方面的策略发展不足。本研究探讨了注意分配和整合的视觉空间和运动系统的儿童与DCD在电机（看+打条件）和电机的条件（看条件）的任务。法三组对照组儿童被用来比较一组儿童与DCD的表现。孩子们坐在一个中央固定点和六个外围目标的前面，并被要求在照明时观看或击中目标。在间隙试验（注视偏移和目标起始之间的间隙）和重叠试验（注视偏移和目标起始重叠）上测量扫视/手部运动延迟。结果在注视条件下，DCD儿童脱离注意力的速度并不比对照组慢。然而，在看+打的条件下，DCD儿童表现出较长的脱离期，这也见于年龄较小的控制儿童。结论.结果表明，DCD儿童可能有赤字的注意力分配的行动，在这两个动作的速度和准确性的运动。结论：注意力脱离可能导致DCD患者的视觉-运动整合问题。
Purpose. Previous research has shown that children with Developmental Coordination Disorder (DCD) have poorly developed strategies for allocating attention. This study examines the allocation of attention and integration of visuo-spatial and motor systems in children with DCD in a motor (look+hit condition) and a motor-free (look condition) task. Method. Three groups of control children were used to compare the performance of a group of children with DCD. Children were seated in front of a central fixation point and six peripheral targets, and were asked to look at or hit targets when illuminated. Saccade/hand movement latencies were measured on gap trials (gap between fixation offset and target onset) and overlap trials (fixation offset and target onset overlapped). Results. DCD children were not slower than controls to disengage attention during the look condition. However, during the look+hit condition the DCD children showed a prolonged disengagement period, which was also seen in younger control children. Conclusions. The results suggest that DCD children may have deficits in the allocation of attention for action, in both the speed of onset of a movement and the accuracy of the movement. It is concluded that attention disengagement may contribute to problems of visuo-motor integration in DCD.
