McGurk效应表示视觉信息对视听言语感知的影响，与没有自闭症的人相比，在自闭症谱系障碍（ASD）患者中观察到的频率较低;原因尚不清楚。一些研究表明，面部结构背景可能在这种差异中发挥作用。更具体地说，ASD患者表现出对面部的局部处理偏见，也就是说，他们在较小程度上处理全局面部信息。本研究以46名健康学生为被试，探讨了面部结构背景在麦格克效应中的作用。采用使用自闭症谱系商（AQ）的模拟方法，我们试图确定这种面部配置背景是否对先前观察到的ASD患者McGurk效应的减少至关重要。唇读和视听音节识别任务进行了评估，通过介绍直立正常，倒正常，直立撒切尔型，倒撒切尔型的脸。当呈现撒切尔型面孔时，发现感知者对错误取向的面部特征敏感，导致他们感知到比正常面孔时更弱的麦格克效应（这被称为麦克撒切尔效应）。此外，McGurk效应在不一致视听条件下，高AQ分数的个体比低AQ分数的个体更弱，无论他们读唇或处理面部配置上下文的能力如何。因此，我们的研究结果不支持这样的假设，即ASD患者由于难以处理面部结构背景而表现出较弱的McGurk效应。
The McGurk effect, which denotes the influence of visual information on audiovisual speech perception, is less frequently observed in individuals with autism spectrum disorder (ASD) compared to those without it; the reason for this remains unclear. Several studies have suggested that facial configuration context might play a role in this difference. More specifically, people with ASD show a local processing bias for faces—that is, they process global face information to a lesser extent. This study examined the role of facial configuration context in the McGurk effect in 46 healthy students. Adopting an analogue approach using the Autism-Spectrum Quotient (AQ), we sought to determine whether this facial configuration context is crucial to previously observed reductions in the McGurk effect in people with ASD. Lip-reading and audiovisual syllable identification tasks were assessed via presentation of upright normal, inverted normal, upright Thatcher-type, and inverted Thatcher-type faces. When the Thatcher-type face was presented, perceivers were found to be sensitive to the misoriented facial characteristics, causing them to perceive a weaker McGurk effect than when the normal face was presented (this is known as the McThatcher effect). Additionally, the McGurk effect was weaker in individuals with high AQ scores than in those with low AQ scores in the incongruent audiovisual condition, regardless of their ability to read lips or process facial configuration contexts. Our findings, therefore, do not support the assumption that individuals with ASD show a weaker McGurk effect due to a difficulty in processing facial configuration context.
