ABSTRACT Motor interference occurs when action execution is hindered by the observation of an incongruent action. The present study used a novel eye-tracking paradigm to test the motor interference effect in 22 preschoolers with autism spectrum disorder (ASD), 14 preschoolers with Williams syndrome (WS), and 18 typically developing (TD) peers. In TD children, performance of a pre-determined action was slower after the observation of an incongruent motor action and faster following observation of a congruent motor action, indicating a motor interference effect. In both the ASD and WS groups, performance was unaffected by the congruent versus incongruent nature of the observed motor action.

减少患有自闭症谱系障碍和威廉姆斯综合症的学龄前儿童的运动干扰

摘要 当动作执行因观察到不一致的动作而受到阻碍时，就会发生电机干扰。本研究使用一种新的眼动追踪范式来测试 22 名患有自闭症谱系障碍 (ASD) 的学龄前儿童、14 名患有威廉姆斯综合征 (WS) 的学龄前儿童和 18 名典型发育 (TD) 同龄人的运动干扰效应。在 TD 儿童中，在观察到不一致的运动动作后，预定动作的表现较慢，而在观察到一致的运动动作后则较快，表明存在运动干扰效应。在 ASD 和 WS 组中，表现不受观察到的运动动作的一致与不一致性质的影响。
