We investigated eye-hand coordination in children with autism spectrum disorders (ASD) in comparison with age-matched normally developing peers. The eye-hand correlation was measured by putting fixation latencies in relation with pointing and key pressing responses in visual detection tasks where a gap-overlap paradigm was used and compared to fixation latencies in absence of manual response. ASD patients showed less efficient eye-hand coordination, which was particularly evident when pointing towards a target was being fixated. The data of normally developing participants confirmed that manual gap effects are more likely for more complex hand movements. An important discrepancy was discovered in participants with ASD: beside normal eye gap effects, they showed no concurrent hand gap effects when pointing to targets. This result has been interpreted as a further sign of inefficient eye-hand coordination in this patient population.
我们研究了自闭症谱系障碍（ASD）儿童与年龄匹配的正常发育同伴之间的手眼协调能力。通过将注视潜伏期与视觉检测任务中的指向和按键反应相关联，测量眼手相关性，在使用间隙重叠范式的情况下，并与无手动反应时的注视潜伏期进行比较。ASD 患者表现出手眼协调能力较差，当指向目标时尤为明显。正常发育参与者的数据证实，手动间隙效应更可能出现在更复杂的手部运动中。在 ASD 患者中发现了一个重要的差异：除了正常的眼间隙效应外，当指向目标时，他们没有同时出现手部间隙效应。这一结果被解释为该患者群体手眼协调能力低下的又一迹象。
