Previous studies showed that working memory (WM) content can guide attention; however, whether working memory capacity (WMC) and state anxiety could affect this remains unclear. This study aimed to examine the effect of WMC and state anxiety on attention guided by WM content. Participants with high and low WMC were assigned to either a neutral or an anxiety condition. They were asked to perform a modified change detection task with irrelevant singletons while their event-related potentials were recorded. N2pc and Pd were observed in the low-WMC and anxiety group, and Pd was observed in both the high-WMC and anxiety and the high-WMC and control groups, whereas neither N2pc nor Pd was found in the low-WMC and control group. These findings suggest that attention is guided or suppressed by WM content, depending on the WMC and anxiety level of the individual. This study provides a new perspective on WM content-guided attention.

工作记忆内容引导注意力

以往的研究表明，工作记忆（WM）内容可以引导注意力；然而，工作记忆能力（WMC）和状态焦虑是否会影响这一点仍不清楚。本研究旨在检验 WMC 和状态焦虑对 WM 内容引导的注意力的影响。具有高和低 WMC 的参与者被分配到中性或焦虑状态。他们被要求对不相关的单例执行修改后的更改检测任务，同时记录他们的事件相关电位。在低 WMC 和焦虑组中观察到 N2pc 和 Pd，在高 WMC 和焦虑组和高 WMC 和对照组中都观察到 Pd，而在低 WMC 和对照组中均未发现 N2pc 和 Pd . 这些发现表明注意力被 WM 内容引导或抑制，取决于个人的 WMC 和焦虑程度。这项研究为 WM 内容引导的注意力提供了一个新的视角。
