In this review, we investigated the influence of happy/pleasurable and sad/unpleasant emotional stimuli on working memory (WM) performance. Twenty-eight out of 356 articles were reviewed. We observed that emotional stimuli were used as mood inductors or as targets comprising the WM task. Results showed that WM modalities were influenced differently when updating, interference resolution, span, and complex tasks were applied. Specifically, we found distinct effects of emotional stimuli for updating tasks, in which (a) verbal modality seems to be impaired regardless of the emotional valence used compared to neutral stimuli, (b) visual updating processes appear to be improved by emotional stimuli as the targets of the task, and (c) emotional words improved interference resolution performance. As for storage, span, and complex WM tasks, sad/unpleasant emotional stimuli seem to decrease both verbal and visuospatial modalities when used as emotional inductors.

情绪刺激的分配如何影响工作记忆任务？概述

在这篇综述中，我们调查了快乐/愉快和悲伤/不愉快的情绪刺激对工作记忆 (WM) 表现的影响。对 356 篇文章中的 28 篇进行了审查。我们观察到情绪刺激被用作情绪感应器或作为构成 WM 任务的目标。结果表明，在应用更新、干扰分辨率、跨度和复杂任务时，WM 模态受到不同的影响。具体来说，我们发现情绪刺激对更新任务的明显影响，其中（a）与中性刺激相比，无论使用何种情绪效价，言语模态似乎都受到损害，（b）情绪刺激似乎改善了视觉更新过程，因为任务的目标，以及（c）情感词提高了干扰解决性能。至于存储、跨度、复杂的WM任务，
