The McGurk Effect

The McGurk effect is a perceptual phenomenon which demonstrates an interaction between hearing and vision in speech perception. It suggests that speech perception is multimodal, that is, that it involves information from more than one sensory modality. The McGurk effect is sometimes called the McGurk-MacDonald effect. It was first described in a paper by Harry McGurk and John MacDonald in 1976 [Source].

  1. Damn. I misread that as the "McGuirk" effect and thought maybe it had to do with being a drunken elementary school soccer coach with a secret life as a masked luchador on Adult Swim.

  2. Hah, I don't buy it. Every time he says "Baa" and you watch his lips, his lips close entirely followed by a pronounced B as one would expect when saying "Baa" But then look at the "pitch changed" version, and in every case, his lips never close entirely, and the "F" sound is formed as his lower lip touches his upper front teeth clearly making a "Faa" sound. In not one instance of the higher pitched "Faa" sounds do his lips ever close entirely, and in every instance of the lower pitched "Baa" his lips are entirely closed.

    My mate and I watched in disbelief for all the wrong reasons.

    Repeated viewings failed to convince.
