Clinical anxiety and acute stress caused by major life events have well-documented detrimental effects on cognitive processes, such as working memory (WM). However, less is known about the relationships of state anxiety or everyday stress with WM performance in non-clinical populations. We investigated the associations between these two factors and three WM composites (verbal WM, visuospatial WM, and n-back updating performance) in a large online sample of non-depressed US American adults. We found a trend for a negative association between WM performance and anxiety, but not with stress. Thus, WM performance appears rather robust against normal variation in anxiety and everyday stress.
重大生活事件引起的临床焦虑和急性应激对认知过程，如工作记忆（WM），具有充分记录的有害影响。然而，在非临床人群中，关于状态焦虑或日常压力与工作记忆表现之间的关系，我们所知甚少。我们在一个由非抑郁的美国成年人组成的大型在线样本中，研究了这两个因素与三种工作记忆组合（言语工作记忆、视觉空间工作记忆和n-回溯更新表现）之间的关联。我们发现工作记忆表现与焦虑之间存在负相关趋势，但与压力无关。因此，工作记忆表现似乎对焦虑和日常压力的正常变化具有较强的抵抗力。
