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.
当动作执行受到不一致动作观察的阻碍时，就会发生运动干扰。本研究采用一种新颖的眼动追踪范式，对22名自闭症谱系障碍（ASD）学龄前儿童、14名威廉姆斯综合征（WS）学龄前儿童和18名发育正常（TD）的同龄人进行运动干扰效应测试。在发育正常的儿童中，观察到不一致的运动动作后，预定动作的执行速度会变慢，而观察到一致的运动动作后则会变快，这表明存在运动干扰效应。在ASD组和WS组中，观察到的运动动作的一致性与否对表现没有影响。
