Attention bias modification (ABM) is an intervention technique that reduces attention bias towards negative stimuli and improves anxiety symptoms. We examined the effect of attention bias modification towards dynamic-angry faces on various indices potentially related to social anxiety. Forty-eight participants with high social anxiety (HSA) were randomly divided into the attention modification program (AMP, n = 24) and attention control condition (ACC, n = 24). They were assessed by behavioral and event-related potential (ERP) methods in pre- and post-test. For results, ABM reduced social anxiety symptoms, changed the mean amplitudes of P100. Besides, we observed a significant correlation between the behavioral and ERP training effect. In sum, this study could provide evidence of the ABM effect of dynamic-angry face processing in HSA individuals.

注意偏差修正 (ABM) 是一种干预技术，可减少对负面刺激的注意偏差并改善焦虑症状。我们研究了对动态愤怒面孔的注意力偏差修正对可能与社交焦虑相关的各种指标的影响。48 名具有高度社交焦虑 (HSA) 的参与者被随机分为注意力调整计划 (AMP, n = 24) 和注意力控制条件 (ACC, n = 24)。他们在测试前和测试后通过行为和事件相关电位 (ERP) 方法进行评估。对于结果，ABM 减少了社交焦虑症状，改变了 P100 的平均幅度。此外，我们观察到行为和 ERP 培训效果之间存在显着相关性。总之，这项研究可以提供 HSA 个体中动态愤怒面部处理的 ABM 效应的证据。
