Individual Differences Observed in McGurk Effect.

Harry McGurk and the McGurk Effect

A significant part of the history of auditory-visual speech processing is the discovery of the way in which auditory and visual speech components, when in conflict, can give rise to an emergent percept. Not many of the present-day young auditory-visual speech researchers know about the history of this finding. Early this year the organisers of AVSP’98 contacted the Australian Institute of Famil...

Modelling the McGurk effect

The current study investigates the McGurk effect by modelling it with neural networks. The simulations are designed to test the two main theories about the moment at which the auditory-visual integration happens. To further analyze the causes behind the McGurk illusion, the neural network that best models the effect is used to simulate the influence of language and the frequency of phonemes on ...

Emotional McGurk Effect

Speaking is a physiological process that manifests in the acoustic and in the optic domain and hence is audible and visible. These two modalities influence each other in perception. Under normal circumstances the speech information in both channels is coherent and complementary and integrated to a percept. But if the information is conflicting and nevertheless integrated then the percept in one...

Reconsidering the McGurk effect

The McGurk effect was studied on 3 groups of subjects differing in age: pre-schoolers (mean: 6 years), elementary-school 4-graders (mean: 11 years) and adults (mean: 24 years). The stimuli included audio-visual combinations of syllables /pa/, /ta/, /ka/, /ba/, /da/, /ga/. The combination of auditorily presented (A) bilabials with visually presented (V) velars, was reported by some subjects as a...
