To evaluate the ability to accurately perceive the limits of action capabilities in children at risk for developmental coordination disorder (DCD).
In Study 1, 9 to 12-year-old children (mean = 10.6 years, SD = 1.09) were identified as at risk for DCD and the accuracy of their perceptual judgments was compared with the judgments of a group of typically developing children (TDC). Two judgment tasks were used: Maximum vertical reach and maximum sitting height. Study 2 tested the hypothesis that a significant correlation would be found between a specific movement task and a related judgment task. Participants were randomly selected (n = 24) 10 and 11-year-old children (mean = 10.5 years, SD = 0.51).
Magnitude of judgment error (absolute error) on all tasks was significantly (p < 0.05) greater in the DCD group than in the TDC group. Study 2 revealed a significant (p < 0.05) correlation between the movement task and the related perceptual task (r = 0.70).
Compared to a typically developing group, children at risk for DCD made less accurate judgments of the limits of their action capabilities. The accuracy of a perceptual judgment was found to correlate with a related movement skill.
评估发育性协调障碍（DCD）风险儿童准确感知动作能力极限的能力。
在研究1中，将9至12岁儿童（平均年龄 = 10.6岁，标准差 = 1.09）确定为有DCD风险，并将他们的感知判断准确性与一组发育正常儿童（TDC）的判断进行比较。使用了两项判断任务：最大垂直伸展和最大坐高。研究2检验了在特定运动任务和相关判断任务之间会发现显著相关性的假设。参与者是随机选取的10岁和11岁儿童（n = 24，平均年龄 = 10.5岁，标准差 = 0.51）。
DCD组在所有任务上的判断误差幅度（绝对误差）均显著（p < 0.05）大于TDC组。研究2显示运动任务与相关感知任务之间存在显著（p < 0.05）相关性（r = 0.70）。
与发育正常组相比，有DCD风险的儿童对其动作能力极限的判断准确性较低。发现感知判断的准确性与相关运动技能相关。
