Interaction occurs in brain when human gets stimuli from different sensory organs such as visual and auditory. Previous behavioral studies have shown that bimodal audiovisual stimuli simultaneously can be discriminated or detected more rapidly and accurately than unimodal visual or auditory stimuli presented alone. Many studies have shown that temporal asynchrony of audio-visual stimuli can influence the integration between visual and auditory stimulus, however, the multisensory mechanisms of asynchrony inputs were not well understood. In this study, we measured the behavioral and EEG data when the visual and auditory stimuli onset asynchrony were presented in the screen. This was done for each of the five different 50-ms subranges of stimulus onset asynchrony. Behavioral results showed that reaction times to the asynchrony audiovisual stimuli were faster that the unimodal stimulus. Moreover, the interaction of the asynchrony input was verified from event related potentials (ERPs). Especially, the results showed that the effect on EEG component around 200ms was largest when visual was presented after the auditory stimuli. This result suggested that might reflect the processing or adjusting for the temporal alignment of audiovisual stimuli.
