研究表明,理解复杂的社交线索取决于认知资源(例如)的可用性。尽管有证据表明执行控制功能可能会影响焦虑(例如),但相对较少的研究检查了广泛性社交恐惧症(GSP)患者的工作记忆。此外,很少有研究探讨威胁相关内容在临床焦虑人群工作记忆表现中的作用。为此,本研究使用威胁相关和中性刺激的操作跨度任务评估了患有广泛性社交恐惧症和非焦虑控制的个体的工作记忆能力(WMC)。结果显示,对于中性词,不焦虑的个体比具有 GSP 的个体表现出更好的 WMC,但对于社交威胁词则不然。相对于中性词,具有 GSP 的个体在威胁词方面表现出更好的 WMC 表现。这些结果表明,患有 GSP 的个体对于显着的、社会相关的信息可能具有相对增强的工作记忆能力。这种针对威胁相关信息的工作记忆能力的增强可能是在 GSP 中练习这些信息的结果。
Research suggests that understanding complex social cues depends on the availability of cognitive resources (e.g.,). In spite of evidence suggesting that executive control functioning may impact anxiety (e.g.,), relatively few studies have examined working memory in individuals with Generalized Social Phobia (GSP). Moreover, few studies have examined the role of threat-relevant content in working memory performance in clinically anxious populations. To this end, the present study assessed working memory capacity (WMC) in individuals with Generalized Social Phobia and non-anxious controls using an Operation Span task using threat relevant and neutral stimuli. Results revealed that non-anxious individuals demonstrated better WMC than individuals with GSP for neutral words, but not for social threat words. Individuals with GSP demonstrated better WMC performance for threat words relative to neutral words. These results suggest that individuals with GSP may have relatively enhanced working memory performance for salient, socially-relevant information. This enhanced working memory capacity for threat relevant information may be the result of practice with this information in GSP.
