Abstract
The McGurk effect is a perceptual phenomenon that demonstrates interaction between hearing and vision in speech perception. This effect may be experienced when a visual of the production of a phoneme (/ka/) is dubbed with a sound recording of a different phoneme being spoken (/pa/), wherein the perceived phoneme is often the third, intermediate phoneme (/ta/). In the present study, we examined the potential individual differences in the McGurk effect among healthy students. The results suggested that people with higher scores for autistic traits might report more /ta/ responses (vision-audio fused responses) in the McGurk condition (visually /pa/ but auditory /ka/) over all experiments. This indicates that such people might show a weak support from the motor system for audio- visual speech perception.
