Children with autism spectrum disorder (ASD) exhibit impairment in helping someone else with a motor action, which may arise from impairment in selecting and preparing motor responses. Five children with ASD and five typically developing children performed a cooperative motor planning task that required them to reach for, lift, and hand an object (hammer or stick) to a researcher. The response, movement, and grasp time were measured. Children with ASD grasped the object longer on trials where they helped, indicating that the action was planned in sequence versus as a whole (i.e., prior to the onset of movement). The hammer object elicited a quicker response than the stick, suggesting the facilitation of planning by tools with inherent action properties. Finally, the increased helping of children with ASD was not mirrored by changes in the response, movement, or grasp time.

孤独症运动障碍儿童运动合作期间运动计划较慢且较困难的初步证据。

自闭症谱系障碍（ASD）儿童在帮助他人进行运动方面表现出障碍，这可能是由于选择和准备运动反应方面的障碍而引起的。五名患有自闭症的孩子和五名典型的发育中的孩子执行了一项协作性的运动计划任务，要求他们伸手拿起物体（锤子或棍子）并将其交给研究人员。测量反应，运动和抓握时间。患有自闭症的儿童在他们提供帮助的试验中更长时间地抓住了该物体，表明该动作是按顺序计划的，而不是整体计划的（即在运动开始之前）。锤子物体引起的反应比棍棒更快，表明具有固有作用特性的工具有助于进行计划。最后，自闭症儿童的帮助增加并未反映出反应的改变，
