Auditory-Visual Speech Processing (AVSP) 2010
Hakone, Kanagawa, Japan
We studied differences between Japanese younger (YA) and older adults (OA) by recording event-related brain potentials (ERP). Participants were asked to identify audio only (AO) and congruent audiovisual (AV) syllables as /ba/ or /ga/). We found age-related ERP changes (N1, P2, and N2 latencies) in Japanese audiovisual speech perception. Whereas the visual influence was sustained (maintained from P2 to N2) in the OA group, the influence was transient (limited only to N1) in the YA group. It seemed that the OA groups slower auditory processing is compensated by visual information.
