在文献中，社交焦虑与认知加工的异常有关，表现为各种认知偏差。这些偏见在多大程度上干扰了社会互动在很大程度上尚不清楚。本研究采用社会判断范式，将社会反馈加工的期望阶段和体验阶段分开。这两个阶段的事件相关电位(ERPs)被记录下来，以检测行为数据可能无法反映的社交焦虑的影响。参与者根据他们的社交焦虑水平被分为两组。高社交焦虑(HSA)组的参与者比低社交焦虑(LSA)组的参与者(即对照组)更有可能预测他们会被同伴拒绝。与LSA组的ERP数据相比，HSA组显示：(A)在社会反馈呈现之前，对社会提示(同伴面孔)的P1成分较大，可能表明存在注意偏差；(B)意外社会接受和意外社会拒绝之间反馈相关负性幅度的差异，可能表明预期偏差；以及(C)P3波幅对社会反馈效价(被接受/被拒绝)的敏感度降低，可能表明经验偏差。这些结果有助于理解构成和维持社交焦虑的认知机制。
Social anxiety has been associated with abnormalities in cognitive processing in the literature, manifesting as various cognitive biases. To what extent these biases interrupt social interactions remains largely unclear. This study used the Social Judgment Paradigm that could separate the expectation and experience stages of social feedback processing. Event-related potentials (ERPs) in these two stages were recorded to detect the effect of social anxiety that might not be reflected by behavioral data. Participants were divided into two groups according to their social anxiety level. Participants in the high social anxiety (HSA) group were more likely to predict that they would be socially rejected by peers than did their low social anxiety (LSA) counterparts (i.e. the control group). Compared to the ERP data of the LSA group, the HSA group showed: (a) a larger P1 component to social cues (peer faces) prior to social feedback presentation, possibly indicating an attention bias; (b) a difference in feedback-related negativity amplitude between unexpected social acceptance and unexpected social rejection, possibly indicating an expectancy bias; and (c) a diminished sensitivity of the P3 amplitude to social feedback valence (be accepted/be rejected), possibly indicating an experience bias. These results could help understand the cognitive mechanisms that comprise and maintain social anxiety.
