Abstract：Objective To study the changes of visual early cognitive processing under visual rotating backgrounds at different speeds when performing different loads of visual tasks.Methods Twenty healthy righthanded university students participated in the experiment.The visual backgrounds were the normal white background and the simulated star background with different rotating speeds.The subjects were asked to perform no-response,selective switch response and selective mental arithmetic tasks and the 12-lead electroencephalogram(EEG) was recorded.Results It was found that the central area had the shortest P1 latencies and the highest P1 peak amplitudes.As compared with tasks performed under white background,the response time and P1 latencies were shortened under rotating background.As compared with tasks performed under white background,the response time and the peak amplitudes of the P1 were increased in selective switch response and selective mental arithmetic tasks under the rotating background.Conclusion Rotating backgrounds accelerated the perception of the visual cognition and increased the priming effect in high load task.Different angular velocities of the rotating background only affected the processing of active inhibition in the selective switch response task.
