A question that has emerged over recent years is whether audiovisual (AV) speech
perception is a special case of multi-sensory perception. Electrophysiological (ERP) studies
have found that auditory neural activity (N1 component of the ERP) induced by speech is
suppressed and speeded up when a speech sound is accompanied by concordant lip
movements. In Experiment 1, we show that this AV interaction is not speech-specific.
Ecologically valid nonspeech AV events (actions performed by an actor such as …

Electrophysiological studies have found that auditory neural activity induced by speech is
suppressed and speeded up when a speech sound is accompanied by concordant lip
movements. These results demonstrate that the visually induced speeding-up and
suppression of auditory N1 amplitude reflect multisensory integrative mechanisms of AV
events that crucially depend on whether vision predicts when the sound occurs.(PsycEXTRA
