急性应激和注意偏向是焦虑障碍和创伤后应激障碍发生和症状保持的两个重要因素。急性应激导致交感神经系统激活以及儿茶酚胺和糖皮质激素分泌增加, 因而影响对威胁刺激的注意偏向。但是急性应激如何影响注意偏向中的注意定向和注意解除尚不清楚。本项目采用点探测任务、威胁线索空间提示任务, 结合恐惧条件反射、眼动和事件相关电位技术, 研究急性应激对注意定向和注意解除影响的认知神经机制。研究结果可为治疗焦虑和创伤后应激障碍提供支持, 为公共卫生管理政策的制定提供建议。

关键词: 心理应激, 注意定向, 注意解除, 神经机制


Acute stress and attentional bias towards threat are two key factors associated with developing and maintaining symptoms of anxiety disorder and PTSD. Acute stress is characterized by high activity of sympathetic nervous system, increased secretion of catecholamine and glucocorticoids. These psychophysical changes have significant effects on attentional bias towards threat. However, how acute stress affects attentional engagement and attentional disengagement of attentional bias is not clear. In this project, we will investigate neural mechanism of acute stress effects on attentional engagement and attentional disengagement towards threat by using modified dot probe task and spatial threat cueing task combine with eye tracking, event related potential as well as fear conditioning technique. The findings can provide guidance for the treatment of anxiety disorder and PTSD, and can help the government make good decision about public health.

Key words: acute stress, attentional engagement, attentional disengagement, neural mechanism
