为探讨长期心理疲劳下射击运动员的反应效果监控能力是否下降，使用事件相关电位技术分析错误相关负波（ERN）幅值的变化。采用Flanker任务，以大学生运动员为研究对象进行预实验，发现该认知任务在诱发ERN方面是有效的。以长期心理疲劳为自变量、行为数据和ERN幅值为因变量探讨射击运动员长期心理疲劳与反应效果监控的关系，发现长期心理疲劳状况下，出现错误后反应延时、正确率降低、ERN幅值变小，但有、无长期心理疲劳组差异不显著，ERN最大波幅点是FCz；因此，长期心理疲劳状况下，射击运动员错误后调整行为受阻，反应效果监控能力有所下降，监控时，大脑额叶中部活动最强。

In order to investigate whether shooters＇ response monitoring ability decreases （In ERP studies, the amplitude of error related negativity decreases） under burnout circumstances, an ERP study was carried out to explore cause-effect relationships of burnout and response monitoring. Burnout was regarded as an independent variable. Operational performances （correct rate, reaction time） and ERN （The modified Flanker task on basis of achievmaent from Yeung et al. is used to evoke ERN. The Flanker task is proved to be valid by the way of un- dergraduate athletes＇ pretest） were regarded as dependent variables. From the result of operational perform- ances, the phenomenon of post-error slowing occurred in burnout group. No burnout group＇s correct rate is bet- ter than that of burnout group, but the difference is not significant From the result of ERN,no burnout group＇s amplitude is bigger than that of burnout group, but the difference is not significant. The most obvious electrode is FCz in ERN. ERN can observe professional athletes＇ burnout, no burnout group＇ s monitoring capability is slightly better than burnout group＇s. Long-term burnout affects post-error adjustment. The frontal central is the most active during response monitoring.
