McGurk effect

English Etymology First described in 1976 in a paper by Harry McGurk and John MacDonald. Noun en phonetics phonology linguistics psychology A perceptual phenomenon where, when the auditory component of one sound is paired with the visual component of another sound, a third and different sound is perceived. en Michael Kenstowicz Michael Kenstowicz The Phonetic Foundations of Phonology 4.5 w:Phonology in Generative Grammar https://archive.org/details/phonologyingener0000kens Cambridge, MA Blackwell Blackwell Textbooks in Linguistics 1994-01 978-1-557-86426-0 191 Finally, let us note two experiments that demonstrate a relation between the auditory and visual modalities that makes sense under the tight bond between particular articulatory and acoustic states implied by a phonological feature. In the so-called McGurk effect, subjects see a video display of a head saying [ba] repeatedly: [ba], [ba], [ba]. The video is synchronized with a recording of [ga], [ga], [ga]. […] subjects hear neither [ga], [ga], [ga] nor [ba], [ba], [ba], but [da], [da], [da] — an illusion whose effect is quite stunning. en Bonny Sands Empirical Approaches to Linguistic Theory 15 Catherine T. Best Perception of Non-native Click Consonant Contrasts: Implications for Theories of Speech Perception Click Consonants 10.1163/9789004424357_006 Boston Brill 2020 978-90-04-23268-6 194 Conversely, and most crucially, McGurk effects for click consonant-vowel syllables were found to be equivalent to those for stop-vowel syllables. These results indicate that McGurk AV integration is strong for coarticulated stop consonant-vowel syllables, but much weaker for isolated release bursts, regardless of whether they are from native or non-native consonants, or are perceived as speech or as non-speech. en eponyms
