Previous findings on gestural impairment in autism are inconsistent, while scant evidence came from Chinese-speaking individuals. In the present study, preschool Chinese-speaking children with typical development and with autism were asked to generate stories from a set of wordless Cartoon pictures. Two groups were matched in chronological age and language developmental age. Their speech and gestures were coded. Compared to children with typical development, children with autism produced fewer gestures and showed lower gesture rate. Besides, children with autism produced fewer emblems and fewer supplementary gestures compared to their TD peers. Unlike children with typical development, children with autism tend to produce emblems for reinforcing, rather than supplementing information not conveyed in speech. Results showed the impairments in integrating the cross-modal semantic information in children with autism.
先前关于自闭症患者手势障碍的研究结果并不一致，而来自讲中文人群的证据很少。在本研究中，要求讲中文的典型发育学龄前儿童和自闭症学龄前儿童根据一组无文字的卡通图片创作故事。两组在实际年龄和语言发育年龄上相匹配。对他们的言语和手势进行编码。与典型发育儿童相比，自闭症儿童的手势较少，手势率较低。此外，与发育正常的同龄人相比，自闭症儿童做出的象征手势和辅助手势更少。与典型发育儿童不同，自闭症儿童倾向于做出象征手势来强化信息，而不是补充言语中未传达的信息。结果显示自闭症儿童在整合跨模态语义信息方面存在障碍。
