While visual information from facial speech modulates auditory speech perception, it is less influential on audiovisual speech perception among autistic individuals than among typically developed individuals. In this study, we investigated the relationship between autistic traits (Autism-Spectrum Quotient; AQ) and the influence of visual speech on the recognition of Rubin's vase-type speech stimuli with degraded facial speech information. Participants were 31 university students (13 males and 18 females; mean age: 19.2, SD: 1.13 years) who reported normal (or corrected-to-normal) hearing and vision. All participants completed three speech recognition tasks (visual, auditory, and audiovisual stimuli) and the AQ-Japanese version. The results showed that accuracies of speech recognition for visual (i.e., lip-reading) and auditory stimuli were not significantly related to participants' AQ. In contrast, audiovisual speech perception was less susceptible to facial speech perception among individuals with high rather than low autistic traits. The weaker influence of visual information on audiovisual speech perception in autism spectrum disorder (ASD) was robust regardless of the clarity of the visual information, suggesting a difficulty in the process of audiovisual integration rather than in the visual processing of facial speech.

具有高自闭症特征的鲁宾花瓶型言语的麦格克效应较弱。


虽然来自面部言语的视觉信息调节听觉言语感知，但它对自闭症患者视听言语知觉的影响小于典型发育个体的影响。在本研究中，我们研究了自闭症特征（自闭症谱系商；AQ）与视觉言语对鲁宾花瓶型言语刺激识别（面部言语信息退化）的影响之间的关系。参与者为 31 名大学生（13 名男性和 18 名女性；平均年龄：19.2，SD：1.13 岁），他们报告听力和视力正常（或矫正至正常）。所有参与者都完成了三项语音识别任务（视觉、听觉和视听刺激）和 AQ-日语版本。结果表明，视觉（即唇读）和听觉刺激的语音识别准确性与参与者的 AQ 没有显着相关。相比之下，高自闭症特征个体的视听言语感知较低自闭症特征个体更不易受到面部言语感知的影响。无论视觉信息的清晰度如何，视觉信息对自闭症谱系障碍（ASD）视听言语感知的影响较弱，这表明视听整合过程存在困难，而不是面部言语的视觉处理。
