将发球旋转作为自变量，采用事件相关电位记录技术，采集被试的反应时和EEG。结果显示：运动员大脑信息加工的通路具有方向性且不可逆，视觉刺激信息沿枕一顶通路传导，国际健将组在枕区激活到顶区激活消退的时间短于二级组，为正确做出决策节省了时间；国际健将组左右半脑对视觉信息的加工表现出不对称性，国际健将组主要启用了右脑枕区资源；在发球判断过程中，国际健将组完成认知活动采用的是一种节省模式，表现为动用大脑枕区和项区资源较少，效率更高。

By using way of rotation as independent variable, the study selected international top players as experts while the national second-grade players as novices, and recorded response time with E-prime and EEG with the event-related potential system. The results indicate a directional and irreversible pathway of information processing in players＇ brain. Visual stimulation information was processed along the occipital-parietal pathway. It was shorter for international top players to reach the peak activation in the occipital area activated than for national second- grade players, which saved time for the right decision making. International top players showed asymmetry in right-left hemispheres during visual information processing. They mainly drew on the right occipital area. Besides, they completed cognitive activity with a kind of saving mode, using fewer resources and getting more efficiency.
