击剑运动员返回抑制能力及抑制特征线索化的事件相关电位研究

The Recurrent Inhibition Ability of Fencer and the ERP Characteristic of Their Inhibition under Induction with Different Cues

目的:研究高水平击剑运动员在不同条件下完成反应-抑制任务的行为优势,探究击剑运动员的位置线索化条件下的抑制能力,以及抑制能力是否受返回抑制影响以及其加工机制。方法:采用综合线索-靶子范式与Go/NoGo范式,在不同线索条件下对不同的靶刺激进行按键反应或抑制反应,采集击剑运动员和普通大学生完成任务的反应时和返回抑制量等行为数据和完成反应抑制任务时的脑电活动。结果:(1)击剑运动员反应时快于普通大学生,其返回抑制量更大;(2)击剑运动员的NoGo条件下的P3波幅显著性大于Go条件;(3)击剑运动员在无效提示下的NoGo-P3波幅大于有效线索提示。结论:击剑运动员视觉搜索效率更高,表现为返回抑制能力强;其抑制能力受线索有效性调节,在无效线索提示条件下抑制能力更强,认知资源投入多,激活速度快。

Objective This study tries to investigate the behavior and biological evidence of the recurrent inhibition ability of fencers under the induction of valid- and invalid-cues. Methods The subjects in this study included elite fencers and college students. Their reaction time and recurrent inhibition volume were collected through event-related potential （ERP） during accomplishing mission following the induction of cue-target paradigm and Go/NoGo paradigm. Results （1）The fencers showed better reaction time and recurrent inhibition ability than the students. （2）The amplitude of P3 in fencers following NoGo cue was higher than following Go cue. （3）For fencer, the amplitude of P3 following NoGo cue and invalid-cue was higher than following NoGo cue and valid-cues. Conclusion Fencers had stronger recurrent inhibition ability and better vision research than the college students, and the better recurrent inhibition ability could be activated by invalid-cues.
