The effect of emotional stimulus content on working memory performance has been investigated with conflicting results, as both emotion-dependent facilitation and impairments are reported in the literature. To clarify this issue, 52 adult participants performed a modified visual 2-back task with highly arousing positive stimuli (sexual scenes), highly arousing negative stimuli (violent death) and low-arousal neutral stimuli. Emotional stimulus processing was found to facilitate task performance relative to that of neutral stimuli, both in regards to response accuracy and reaction times. No emotion-dependent differences in false-alarm rates were found. These results indicate that emotional information can have a facilitating effect on working memory maintenance and processing of information.
情绪刺激内容对工作记忆表现的影响一直存在争议，因为文献中既有情绪依赖的促进作用，也有情绪依赖的损害作用。为了澄清这个问题，52 名成年参与者进行了一项改良的视觉 2 -back 任务，其中包括高度唤起的积极刺激（性场景）、高度唤起的消极刺激（暴力死亡）和低唤起的中性刺激。研究发现，与中性刺激相比，情绪刺激处理在反应准确性和反应时间方面都促进了任务表现。在错误警报率方面没有发现情绪依赖的差异。这些结果表明，情绪信息可以对工作记忆的维持和信息处理产生促进作用。
