The present study investigated whether the processing of social threat words was modulated by social anxiety used by recording electroencephalogram signals during the Stroop task. Behavioral results indicated that the High Social Anxiety (HSA) group exhibited slower RT than the Low Social Anxiety (LSA) group, and both groups had faster RTs when responding to threat words compared to neutral words. ERP data showed that threat words elicited more positive P2, compared with neutral words, in both groups. Neutral words elicited larger early posterior negativity (EPN) and social threat words elicited more positive LPP in the LSA group only. The HSA group did not exhibit the emotional effects of EPN and LPP. These data indicate that social anxiety can modulate the processing of social threat words.
本研究采用 Stroop 任务，通过记录脑电图信号，考察社交焦虑是否会调节对社会威胁词的加工。行为结果表明，高社交焦虑（HSA）组的反应时比低社交焦虑（LSA）组慢，且两组对威胁词的反应快于对中性词的反应。ERP 数据显示，与中性词相比，两组的威胁词都诱发出更正的 P2。仅在 LSA 组中，中性词诱发出更大的早期后负向波（EPN），而社会威胁词诱发出更正的晚期正成分（LPP）。HSA 组没有表现出 EPN 和 LPP 的情绪效应。这些数据表明，社交焦虑可以调节对社会威胁词的加工。
