【摘要】 与低社交焦虑者相比,高社交焦虑者对自我相关信息和外部威胁刺激都表现出较多的注意偏向。一些研究考察了高社交焦虑者在自我相关信息与外部社交线索之间的注意偏向,但没有得出一致的结论。因此,本研究使用修改的点探测任务,记录了16名高社交焦虑者和20名低社交焦虑者对三种"自我中性-他人情绪"面孔对的反应时和脑电。结果显示,两组被试对自我相关信息的反应时更快并且受到了不同情绪效价的调节。高社交焦虑组比低社交焦虑组对所有面孔对都产生了更大的P1波幅和更小的N170波幅;两组被试在自我-中性与他人-愤怒面孔对上诱发的P2波幅比另外两种面孔对都更大。这些结果表明,两组被试会将注意资源优先分配到自我相关信息上,愤怒面孔对这种资源分配的影响最大。与低社交焦虑者相比,高社交焦虑者对面孔对都表现出更多的注意警觉和更少的结构编码并对自我-中性与他人-愤怒面孔对投入了更多的注意资源。更多还原

【Abstract】 Compared to low social anxiety individuals, high social anxiety individuals show a more significant attentional bias toward self-relevant information and externally threatening stimuli. Several studies have examined the attentional bias between self-relevant information and external social cues in high social anxiety individuals,but no consistent conclusions have been drawn. Therefore, the present study used a modified dot-probe task to record the response times and EEGs of 16 high-social-anxious and 20 low-social-anxious subjects in three "self-neutral-other-emotional" face pairs. Results showed that both groups responded faster to self-relevant information and were moderated by different emotional potencies. The high social anxiety group produced larger P1 amplitudes and smaller N170 amplitudes than the low social anxiety group for all face pairs, and both groups evoked larger P2 amplitudes for the self-neutral and other-angry face pairs than for the other two face pairs. These results suggest that subjects in both groups prioritize allocating attentional resources to self-relevant information,with angry faces having the most significant effect on this resource allocation. High social anxiety individuals showed more attentional vigilance and less structural encoding. They devoted more attentional resources to the self-neutral versus other-angry face pairs than low social anxiety individuals.更多还原
