It has been suggested that children with autism are particularly deficient at imitating novel gestures or gestures without goals. In the present study, we asked high-functioning autistic children and age-matched typically developing children to imitate several types of gestures that could be either already known or novel to them. Known gestures either conveyed a communicative meaning (i.e., intransitive) or involved the use of objects (i.e., transitive). We observed a significant interaction between gesture type and group of participants, with children with autism performing known gestures better than novel gestures. However, imitation of intransitive and transitive gestures did not differ across groups. These findings are discussed in light of a dual-route model for action imitation.
有人提出，患有自闭症的儿童在模仿新颖手势或无目的手势方面尤其不足。在本研究中，我们要求高功能自闭症儿童和年龄匹配的正常发育儿童模仿几种对他们来说可能已知或新颖的手势类型。已知手势要么传达交际意义（即不及物的），要么涉及物体的使用（即及物的）。我们观察到手势类型与参与者组之间存在显著交互作用，自闭症儿童模仿已知手势的表现优于新颖手势。然而，不及物和及物手势的模仿在不同组之间没有差异。根据动作模仿的双路径模型对这些发现进行了讨论。
