In one of the few studies examining working memory processes in social anxiety disorder (SAD), Amir and Bomyea (2011) recruited participants with and without SAD to complete a working memory span task with neutral and social threat words. Those with SAD showed better working memory performance for social threat words compared to neutral words, suggesting an enhancement in processing efficiency for socially threatening information in SAD. The current study sought to replicate and extend these findings. In this study, 25 participants with a principal diagnosis of SAD, 24 anxious control (AC) participants with anxiety disorders other than SAD, and 27 healthy control (HC) participants with no anxiety disorder completed a working memory task with social threat, general threat, and neutral stimuli. The groups in the current study demonstrated similar working memory performance within each of the word type conditions, thus failing to replicate the principal findings of Amir and Bomyea (2011). Post hoc analyses revealed a significant association between higher levels of anxiety symptomatology and poorer overall WM performance. These results inform our understanding of working memory in the anxiety disorders and support the importance of replication in psychological research. (PsycINFO Database Record
在少数几项研究中, Amir 和 Bomyea(2011)对患有社交焦虑症(SAD)和不患有 SAD 的参与者进行了研究,以完成一项带有中性和社交威胁词汇的工作记忆跨度任务。与中性词相比,患有 SAD 的参与者在处理社交威胁信息时表现出更好的工作记忆性能,这表明 SAD 患者对社交威胁信息的处理效率得到了提高。本研究旨在复制和扩展这些发现。在这项研究中,25 名 SAD 主要诊断患者、24 名患有除 SAD 以外的焦虑症的焦虑控制(AC)患者和 27 名无焦虑症的健康对照(HC)参与者完成了一项带有社交威胁、一般威胁和中性刺激的工作记忆任务。当前研究中的各组在每个单词类型条件下表现出相似的工作记忆性能,因此未能复制 Amir 和 Bomyea(2011)的主要发现。事后分析显示,焦虑症状的严重程度与整体 WM 表现较差之间存在显著关联。这些结果使我们更好地理解了焦虑症患者的工作记忆,支持了在心理学研究中进行复制的重要性。
