摘要/Abstract

摘要： 为探究动态线索提示下,网球运动员的认知加工方式及大脑活动特征,采用“专家—新手”范式以及用动态线索刺激材料改编的“提示—目标任务”,借助事件相关电位技术,记录并分析专家组(网球运动员10人)和新手组(普通大学生10人)执行反应任务时的行为和脑电。结果发现,在动态线索条件下,专家组被试完成目标刺激任务的反应时较新手组更短,正确率更高;并且,大脑活动显示,在动态线索条件下,目标刺激出现前,专家组被试的CNV成分面积大于新手组;目标刺激出现后,专家组的早期N1潜伏期显著大于新手组,晚期P300波峰显著高于新手组。由此认为,在动态线索提示下,网球运动员较新手具有认知加工优势,可以更快更准地进行反应;同时在准备过程中投入的认知资源更多;在反应时将注意集中于关键信息,更加高效的分配认知资源。

Abstract: In order to investigatetennis players' mode of perception and their brain activity features under the dynamic cue condition, the study recorded and analyzed through the "expert-novice" paradigm and the event-related potential (ERP) technology the behaviors and EEG data of expert group (10 tennis players) and novice group (10 university students) in performing the modified cue-target tasks adapted from dynamic cue materials. The results showed that under the dynamic cue condition, tennis players had shorter reaction time and better accuracy than the novices in completing target-stimulated tasks; in addition, brain activity revealed that before the stimulus occurred, expert group's CNV area was larger than that of the novice group under the dynamic cue condition; after the stimulus occurred, expert group's early latency of N1 was longer than that of the novice group, and their late P300 peak was significantly higher than that of the novice group. It can be inferred that under dynamic cue condition, tennis players have advantage over novices in perception, thus enabling them to react more quickly and accurately; invest more resources in the preparation period; focus on critical information and as a result distribute their cognitive resources more efficiently.

Key words: dynamic cues, tennis players, cognitive process, event-rolatecl potential(ERP)
