以7名乒乓球专业运动员和9名普通大学生为被试，在大屏幕和小屏幕不同刺激呈现条件下选取国家乒乓球女队队员郭跃赢球比赛视频片段进行播放，探讨在视觉刺激下，不同刺激呈现条件对运动员和普通大学生的EEG的影响。结果表明：被试接受视觉刺激时左侧额叶脑电激活水平明显高于右侧，大学生在观看大屏幕时顶区、颞区和枕区的β波激活水平明显高于观看小屏幕时β波激活水平；而运动员在观看大屏幕时β波激活水平却比小屏幕时低，而顶区、颞区和枕区的α波和θ波只在运动水平的主效应上表现出显著水平。

The participants of this study were seven professional table tennis players and nine ordinary college stu-dents. The winning game of Guo Y ue, a player of the Chinese Women s Table Tennis Team, was played on a com- puter and on a large screen. The purpose was to utilize EEG to examine the neural activity associated with two kinds of screen tasks. It was shown that when watching videos, a in the left frontal region increased more than that in the right frontal region. When watching videos on the large screen, the students＇ β in the parietal, temporal, and occip- ital regions increased more than watching the game on the computer. The professional table tennis players＇ β showed a tendency of decline, a and β frequencies were significantly different between the exercise levels in the pari-etal, temporal, and occipital regions.
