我们经常需要过滤掉分心，以便专注于工作记忆（WM）参与的主要任务。先前的研究表明，在视觉工作记忆维持期间呈现的负面与中性干扰显著损害中性信息的记忆。然而，工作记忆的内容在本质上往往也是情感的。我们在这里要解决的问题是，当视觉工作记忆和记忆项目都包含情感信息时，附带信息如何影响视觉工作记忆。我们提出了情感与中性的话在维护间隔的情感视觉WM面临的任务。参与者将两张愤怒或快乐的面孔编码到WM中，在9秒的维持期内，一个消极的，积极的或中性的单词在屏幕上闪烁三次。一个单一的中立的测试面对检索与脸的身份，要么存在或不存在在前面的研究阵列。WM愤怒的脸身份显着更好时，一个情绪化的（消极或积极）与中性（或没有）的话。与此相反，工作记忆的快乐面孔身份没有显着影响的字价。这些研究结果表明，在干预刺激内的情绪的存在提高了视觉工作记忆中保持的威胁相关信息的情感价值，从而提高了性能。此外，我们表明，偶发事件，情感的性质并不总是分散正在进行的WM任务。
We are often required to filter out distraction in order to focus on a primary task during which working memory (WM) is engaged. Previous research has shown that negative versus neutral distracters presented during a visual WM maintenance period significantly impair memory for neutral information. However, the contents of WM are often also emotional in nature. The question we address here is how incidental information might impact upon visual WM when both this and the memory items contain emotional information. We presented emotional versus neutral words during the maintenance interval of an emotional visual WM faces task. Participants encoded two angry or happy faces into WM, and several seconds into a 9 s maintenance period a negative, positive, or neutral word was flashed on the screen three times. A single neutral test face was presented for retrieval with a face identity that was either present or absent in the preceding study array. WM for angry face identities was significantly better when an emotional (negative or positive) versus neutral (or no) word was presented. In contrast, WM for happy face identities was not significantly affected by word valence. These findings suggest that the presence of emotion within an intervening stimulus boosts the emotional value of threat-related information maintained in visual WM and thus improves performance. In addition, we show that incidental events that are emotional in nature do not always distract from an ongoing WM task.
