Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.
社交焦虑（SA）涉及与害怕被评价相关的多种认知症状，包括预期偏差和记忆偏差。我们研究了记忆偏差是否受社交焦虑中社交反馈预期偏差的影响。我们假设，面对社交评价事件时，社交焦虑程度较高的人对未来反馈会表现出消极的预期偏差。此外，我们预测社交焦虑中反馈的记忆偏差将由预期偏差介导。94名本科生（55名女性，平均年龄 = 19.76岁）接受了一项分两次进行的任务，该任务测量了对未知同龄人反馈的预期（第一次访问）和记忆（第二次访问）。结果表明，较高水平的社交焦虑与消极的预期偏差相关。社交焦虑与记忆偏差之间存在一种由预期偏差介导的间接关系。结果表明，预期偏差处于从社交焦虑到社交评价消极记忆偏差的因果路径中。
