急性應(yīng)激對威脅刺激注意定向和注意解除的影響:認知神經(jīng)機制研究
發(fā)布時間:2018-09-18 09:57
【摘要】:急性應(yīng)激和注意偏向是焦慮障礙和創(chuàng)傷后應(yīng)激障礙發(fā)生和癥狀保持的兩個重要因素。急性應(yīng)激導(dǎo)致交感神經(jīng)系統(tǒng)激活以及兒茶酚胺和糖皮質(zhì)激素分泌增加,因而影響對威脅刺激的注意偏向。但是急性應(yīng)激如何影響注意偏向中的注意定向和注意解除尚不清楚。本項目采用點探測任務(wù)、威脅線索空間提示任務(wù),結(jié)合恐懼條件反射、眼動和事件相關(guān)電位技術(shù),研究急性應(yīng)激對注意定向和注意解除影響的認知神經(jīng)機制。研究結(jié)果可為治療焦慮和創(chuàng)傷后應(yīng)激障礙提供支持,為公共衛(wèi)生管理政策的制定提供建議。
[Abstract]:Acute stress and attention bias are two important factors in the occurrence and maintenance of anxiety disorders and post-traumatic stress disorders. Acute stress leads to activation of the sympathetic nervous system and increased secretion of catecholamines and glucocorticoids, thereby affecting attention bias to threatening stimuli. But how acute stress affects attention in attention bias Orientation and attentional resolution are not yet clear. The project used point detection, threat cue cue spatial cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue cue To provide suggestions for the formulation of public health management policies.
