The present study is the first to compare the examined electrophysiological activity of facial and textual feedback of students with social anxiety after they finished a visual search task. Compared to textual feedback, facial feedback is much more effective. Specifically speaking, positive facial feedback caused stronger feedback-related negativity (FRN), and negative facial feedback caused late positive potential (LPP) of stronger amplitude. These changes in the FRN component (associated with feedback) and LPP (related to controlled attention engagement) provide clues about the interplay between anxiety and attention allocation in processing facial feedback. The results have implications for identifying the feedback format that will be most helpful for individuals with social anxiety.
本研究首次比较了社交焦虑症学生在完成视觉搜索任务后，面部和文本反馈的检查后电生理活动。与文本反馈相比，面部反馈的效果要好得多。具体来说，积极的面部反馈会引起更强的反馈相关负波（FRN），而消极的面部反馈会引起更强烈的晚期正电位（LPP）。FRN 成分（与反馈相关）和 LPP（与控制注意力投入相关）的这些变化为焦虑与处理面部反馈时的注意力分配之间的相互作用提供了线索。研究结果对确定对社交焦虑症患者最有帮助的反馈方式具有启示意义。
