威胁刺激下高焦虑跆拳道运动员视觉搜索的早期加工特征

On Early Processing Characteristics of Visual Search for Taekwondo Athletes under High-Anxiety Threats

为了探讨威胁刺激下跆拳道运动员视觉搜索的早期加工特征,采用"专家-新手"范式,通过事件相关电位技术,对高焦虑状态下跆拳道运动员和普通大学生(各20人)视觉搜索的早期P1,N1成分进行考察.得出高焦虑状态下跆拳道运动员对威胁性信息更为敏感,对威胁刺激的警觉性更高,在视觉搜索早期自动化加工阶段具有显著的专家优势,其机制为对威胁性刺激的注意警觉.

The present research deals with the studies of early processing characteristics of visual search for taekwondo athletes who were under high-anxiety threats.In this research,＂expert-novice＂paradigm has been used and event-related potential（ERP）been recorded to study the early P1 and N1 components of visual search on taekwondo athletes with high anxiety and ordinary undergraduates（20 participants each）.It is concluded that Taekwondo athletes with high anxiety,who have obvious expert advantage in visual search early processing period,are more sensitive to threatening information and more alert to threats.The mechanism is attention alert to threats.
