Studies on simple vision and audio attention have been carried out for a long time, but the research of crosschannel 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 visualauditory stimalation, and different impacts of visual and auditory integration occured on different conditions.
