本研究采用S1-S2匹配实验范式，探讨视觉大小变化对听觉强度辨别的影响。行为学结果表明，当听觉强度变化伴随着不一致的视觉变化时，被试在辨别听觉强度变化上犯的错误更多，花费的时间也更多，而对于一致的视听刺激，尤其是在听觉刺激变化的情况下，被试的表现更好。事件相关电位差波显示，视听互动多模态不匹配的信息处理激活右额叶和左中央顶叶皮层约300-400毫秒后S1发作。(C)2014爱思唯尔爱尔兰有限公司版权所有。
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.
