Children with autism spectrum disorders (ASD) often exhibit challenges with visuomotor adaptation. This study explored whether enlarged visual error feedback could enhance motor adaptability in children with and without ASD. Thirty-five children, ages 6 to 10, completed two center-out computerized adaptation tasks. In these tasks, the visual feedback of their hand movement error was provided in either a regular (gain = 1:1) or enhanced (gain = 1:2) ratio. Results indicated that children with ASD had reduced visuomotor adaptability compared to their peers during the regular feedback task. However, in the enhanced feedback task, children with ASD showed positive after-effects on a key motor planning measure, implying that they might be capable of adapting to visual distortions. Despite this, the lack of significant differences between the tasks suggests that while enhanced visual feedback may offer some benefits, it is unlikely to fully offset the compromised visuomotor adaptability. Meanwhile, the ASD group demonstrated an association between fine motor skills and visuomotor adaptability during the regular task. Further approaches beyond enhancing visual feedback need to be explored for a better understanding of the mechanisms behind kinematic adaptation in ASD.
患有自闭症谱系障碍（ASD）的儿童在视运动适应方面常常表现出困难。本研究探讨了放大的视觉误差反馈是否能增强患有和未患有ASD的儿童的运动适应性。35名6至10岁的儿童完成了两项从中心向外的计算机化适应任务。在这些任务中，他们手部运动误差的视觉反馈以常规（增益 = 1:1）或增强（增益 = 1:2）的比例提供。结果表明，在常规反馈任务中，与同龄人相比，患有ASD的儿童视运动适应性降低。然而，在增强反馈任务中，患有ASD的儿童在一项关键的运动计划指标上表现出积极的后效应，这意味着他们可能能够适应视觉扭曲。尽管如此，任务之间缺乏显著差异表明，虽然增强的视觉反馈可能会带来一些益处，但不太可能完全弥补受损的视运动适应性。同时，ASD组在常规任务中表现出精细运动技能与视运动适应性之间的关联。需要探索除增强视觉反馈之外的进一步方法，以更好地理解ASD中运动学适应背后的机制。
