Accurate time perception is crucial for hearing (speech, music) and action (walking, catching). Motor brain regions are recruited during auditory time perception. Therefore, the hypothesis was tested that children (age 6–7) at risk for developmental coordination disorder (rDCD), a neurodevelopmental disorder involving motor difficulties, would show nonmotor auditory time perception deficits. Psychophysical tasks confirmed that children with rDCD have poorer duration and rhythm perception than typically developing children (N = 47, d = 0.95–1.01). Electroencephalography showed delayed mismatch negativity or P3a event-related potential latency in response to duration or rhythm deviants, reflecting inefficient brain processing (N = 54, d = 0.71–0.95). These findings are among the first to characterize perceptual timing deficits in DCD, suggesting important theoretical and clinical implications.

运动障碍儿童的听觉时间知觉较差

准确的时间感知对于听觉(语音、音乐)和动作(行走、捕捉)至关重要。在听觉时间感知期间招募运动大脑区域。因此,该假设被检验为存在发育性协调障碍 (rDCD)(一种涉及运动障碍的神经发育障碍)风险的儿童(6-7 岁)会表现出非运动听觉时间知觉缺陷。心理物理任务证实,与正常发育的儿童相比,rDCD 儿童的持续时间和节奏感知较差(N  = 47,d  = 0.95–1.01)。脑电图显示延迟错配阴性或 P3a 事件相关电位潜伏期响应持续时间或节律异常,反映大脑处理效率低下 ( N  = 54, d = 0.71–0.95)。这些发现是最早表征 DCD 中知觉时间缺陷的发现之一,表明了重要的理论和临床意义。
