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.
在这项研究中，我们使用电生理技术研究了刺激驱动的注意力在社交焦虑个体注意偏差中的作用。为此，我们在点探测任务中使用静态和动态面部表情作为刺激。结果表明，在行为上，高社交焦虑（HSA）组在不一致试验中的反应时间长于一致试验，并且表现出比低社交焦虑（LSA）组更高的试验水平偏差评分可变性。在电生理学方面，我们发现与 LSA 组相比，HSA 组在静态条件下对厌恶面部表情的 N2pc 振幅增强，而在动态面部表情条件下，这种差异消失了。研究结果表明，具有最大情绪强度的面孔更容易引起社交焦虑个体的初始注意。
