Multisensory interactions elicited by audiovisual stimuli presented peripherally in a visual attention task: a behavioral and event-related potential study in humans.
J Clin Neurophysiol. 2009 Dec; 26(6):407-13.JC

Abstract

We applied behavioral and event-related potential measurements to study human multisensory interactions induced by audiovisual (AV) stimuli presented peripherally in a visual attention task in which an irrelevant auditory stimulus occasionally accompanied the visual stimulus. A stream of visual, auditory, and AV stimuli was randomly presented to the left or right side of the subjects; subjects covertly attended to the visual stimuli on either the left or right side and promptly responded to visual targets on that side. Behavioral results showed that responses to AV stimuli were faster and more accurate than those to visual stimuli only. Three event-related potential components related to AV interactions were identified: (1) over the right temporal area, approximately 200 to 220 milliseconds; (2) over the centromedial area, approximately 290 to 310 milliseconds; and (3) over the left and right ventral temporal area, approximately 290 to 310 milliseconds. We found that these interaction effects occurred slightly later than those reported in previously published AV interaction studies in which AV stimuli were presented centrally. Our results suggest that the retinotopic location of stimuli affects AV interactions occurring at later stages of cognitive processing in response to a visual attention task.
