McGurk效应的影响因素与神经基础

This is the authors' abstract. We don't add key points for this paper.

The McGurk effect is a typical audiovisual integration phenomenon, influenced by characteristics of physical stimuli, attentional allocation, the extent that individuals rely on visual or auditory information in processing, the ability of audiovisual integration, and language/culture differences. Key visual information that leads to the McGurk effect is mainly extracted from the mouth area of the talker. The McGurk effect implicates both audiovisual integration (which occurs in the early processing stage and is related to the activation of superior temporal cortex) and the conflict of the incongruent audiovisual stimuli (which occurs in the late processing stage and is related to the activation of inferior frontal cortex). Future studies should further investigate the influence of social factors on the McGurk effect, pay attention to the relationship between unimodal information processing and audiovisual integration in the McGurk effect, and explore the neural mechanisms of McGurk effect with computational modeling.
