摘要：

单纯的视觉注意或听觉注意的研究已经进行了很长时间，但是对于跨通道注意的脑机理研究仍处在较新的阶段。本研究通过心理学实验手段，在只注意视觉刺激、只注意听觉刺激和同时注意视听觉刺激的条件下，记录对每种刺激的反应时间。再通过对反应时间和正确率的分析，研究选择性注意和分隔注意对视听觉统合的影响，并对不同条件下的视听觉统合进行比较。分析数据包括正确率和刺激的反应时间,结果证实前置的空间和时间线索在视听觉刺激中具有重要意义；不同条件下的选择性注意对视听觉统合产生不同影响。

Studies on simple vision and audio attention have been carried out for a long time, but the research of crosschannel attention mechanism for the brain is still in a relatively new stage. In this study, we used experimental psychology means to pay attention on only visual stimulation, only auditory stimulation and pay attention to visual and auditory simultaneously stimulation and recorded response times under every stimulation condition. Analyzing the reaction time and accuracy analysis, we researched the impact of visual and auditory integration by selective attention, and separated the attention and compare data of visual and auditory integration under different conditions of visual and auditory integration.The experimental results showed the pretrial spatial and temporal cues were important in visualauditory stimalation, and different impacts of visual and auditory integration occured on different conditions.
