Randomized Controlled Trial
Age-related multisensory integration elicited by peripherally presented audiovisual stimuli.
Although age-related multisensory integration has been investigated previously, the effects of aging on multisensory integration elicited by peripherally presented audiovisual (AV) stimuli remain unclear. In this study, visual, auditory, and AV stimuli were randomly presented to the left or the right of the central fixation point; during this time, participants (young and old adults) were asked to respond promptly to target stimuli. ⋯ We found that the time window of AV behavioral facilitation in elderly participants was longer but more delayed than that in the young participants when the AV stimuli were presented peripherally. This finding also further confirmed that peripheral resolution decreased with age.
