Abstract

Many studies have shown that temporal asynchrony of visual-auditory stimuli can influence the interaction between visual and auditory stimulus, however, the multisensory mechanisms of asynchrony inputs were not well understood. In this study, the visual and auditory stimuli onset asynchrony (SOA= ±400 ms, ±150 ms, 0 ms), only the visual stimulus was attended. Behavioral data and Event-Related Potentials (ERPs) were recorded. We found that when the SOA was -150ms, the reaction time was the fastest and hit rate was the highest, and the N1 latency of biomodal AV was earlier than the sum of unimodal A and unimodal V in auditory preceding condition.
