This study used a S1-S2 matching paradigm to investigate the influences of visual (size) change on auditory intensity discrimination. Behavioral results showed that subjects made more errors and spent more time to discriminate change in auditory intensity when it was accompanied by an incongruent visual change, while the performance for congruent audiovisual stimuli was better especially if there is a change in auditory stimuli. Event-related potential difference waves revealed that audiovisual interactions for multimodal mismatched information processing activated the right frontal and left centro-parietal cortices around 300-400 ms post S1-onset.
