这项研究使用眼球跟踪方法评估了26名年龄从5岁到15岁的儿童的视听言语感知，其中一半患有自闭症谱系障碍(ASD)，另一半具有典型发育。考虑到ASD儿童对他人面部凝视的特征减少，人们假设他们会表现出视觉信息对听觉语言的影响减弱。在一系列听觉、视觉和视听言语知觉任务中，对反应进行了比较。即使当注意力集中在说话者的脸上时，自闭症儿童的视觉影响也比典型的发育对照组要小。这表明ASD儿童在视听语音处理方面存在根本差异，这可能导致他们的语言和沟通障碍。
This study used eye-tracking methodology to assess audiovisual speech perception in 26 children ranging in age from 5 to 15 years, half with autism spectrum disorders (ASD) and half with typical development. Given the characteristic reduction in gaze to the faces of others in children with ASD, it was hypothesized that they would show reduced influence of visual information on heard speech. Responses were compared on a set of auditory, visual, and audiovisual speech perception tasks. Even when fixated on the face of the speaker, children with ASD were less visually influenced than typical development controls. This indicates fundamental differences in the processing of audiovisual speech in children with ASD, which may contribute to their language and communication impairments.
