中文摘要：

运用眼动记录和事件相关电位（ERP）技术,以43名不同等级网球选手为研究对象,采用等概率Go/Nogo任务,记录被试判断抽球技术动作时的行为特征,并通过记录ERP成分揭示不同等级网球选手抑制控制能力的差异。结果显示：在判断抽球技术的过程中,＂持拍手臂及球拍＂以及运动员移动的躯体信息是专家网球选手关注的重点区域,且在ERP成分上出现了明显的Nogo-N2效应,但组间无显著性差异,表明选手在对刺激任务的监控过程中均投入了较多的认知资源。可见,专家网球选手对抽球技术判断速度快、准确率高的优势主要是由视觉搜索模式的差异造成的。这种对重点信息精细加工的视觉搜索策略,减少了预测过程中信息加工的总量和内部反应延迟,是影响选手判断技术动作速度和准确性的关键因素。

英文摘要：

Using Ocular Movement Recording methods,Event-Related Potential Technology and the Go/Nogo paradigm,43 different levels of tennis playersas research object,their behavior characteristics and the ERP components were recorded. The results showed that the main AOI were racquet and trunk. TheNogo-N2 effects were related to response inhibition processes,but there were no significant differences between groups. The findings indicated that the expertperformance is caused by their visual search pattern together with inhibitory control ability. But the fine processing of the visual search strategy of key informa-tion,to reduce the amount of information processing in the process of the prediction and internal response delay,is a key factor influencing the accuracy of thejudgment technique action.
