Abstract
The McGurk effect is a perceptual illusion, which demonstrates an interaction between auditory and visual sensory systems in speech perception. If a mismatch between the perception of a sound and the accompanying visual input occurs, it has been observed that the unified perception of both modalities fuses to a novel percept that neither matches the auditory nor the visual stimulus. This effect only appears in 60-80% of trials containing mismatching information.
The present study was designed to clarify the conditions under which this effect occurs and to identify cortical sources associated with it. We were interested in the potential influence of induced ongoing brain oscillations associated with varying perception.
Trials, in which a fusion was reported were compared to trials in which the subjects responded to the visual input. Although both, congruent and incongruent trials were presented, only varying perception during the presentation of identical incongruent stimuli was analyzed.
