The McGurk illusion (VIDEO)

eLife

Caption

This video is a brief illustration of the famous McGurk illusion, where the auditory perception of a syllable is altered by mismatched lip movements. The soundtrack is from a recording where the actress utters the syllable /pa/, whereas in the video she utters /ka/. When the video and soundtracks are approximately synchronous, observers often experience the McGurk illusion, and perceive the syllable /ta/. We can see the π‘€πΆπ·π‘π‘œπ‘Ÿπ‘Ÿ population response cluster around the mouth area, and how its magnitude scales with the probability of experiencing the illusion.
