In this study we investigated the role of stimulus-driven attention in the attentional bias in individuals with social anxiety using electrophysiological technique. For this purpose, we employed static and dynamic facial expressions as stimuli in a dot-probe task. The results revealed that in behavior high socially anxious (HSA) group had longer response time in incongruent trials than congruent trials, and showed higher trial level-bias score variability than low socially anxious (LSA) group. In electrophysiology, we found that compared to LSA group, HSA group showed an enhanced N2pc amplitude to disgust facial expressions in static condition, whereas this difference was eliminated in dynamic facial expression condition. The results suggest the faces with peak emotion intensity are more likely to capture initial attention of individuals with social anxiety.

社交焦虑和对动态厌恶表情的关注:N2pc的证据不再引起关注。

在这项研究中,我们研究了使用电生理技术,在社交焦虑症患者的注意偏见中,刺激驱动的注意的作用。为此,我们在点探针任务中采用了静态和动态面部表情作为刺激。结果表明,在行为上较高的社交焦虑(HSA)组在不一致的试验中比在同等的试验中有更长的响应时间,并且显示出较高的试验水平偏见得分变异性高于低社交焦虑(LSA)组。在电生理学方面,我们发现与LSA组相比,HSA组在静态条件下显示出更高的N2pc幅值,从而使面部表情令人反感,而在动态面部表情条件下,这种差异得以消除。
