This study disentangled the influences of language and social processing on communication in autism spectrum disorder (ASD) by examining whether gesture and speech production differs as a function of social context. The results indicate that, unlike other adolescents, adolescents with ASD did not increase their coherency and engagement in the presence of a visible listener, and that greater coherency and engagement were related to lesser social and communicative impairments. Additionally, the results indicated that adolescents with ASD produced sparser speech and fewer gestures conveying supplementary information, and that both of these effects increased in the presence of a visible listener. Together, these findings suggest that interpersonal communication deficits in ASD are driven more strongly by social processing than language processing.
本研究通过考察手势和言语表达是否因社会情境而异，厘清了语言和社会加工对自闭症谱系障碍（ASD）患者沟通的影响。结果表明，与其他青少年不同，患有ASD的青少年在有可见听众在场时，其连贯性和参与度并未增加，且更高的连贯性和参与度与较少的社会和沟通障碍相关。此外，结果还表明，患有ASD的青少年言语表达更稀疏，传达补充信息的手势更少，且在有可见听众在场时，这两种影响都会增强。总之，这些发现表明，ASD患者的人际沟通缺陷更多是由社会加工而非语言加工驱动的。
