Previous studies have shown that negatively valenced information impaired working memory performance due to an attention-capturing effect. The present study examined whether negative valence could also facilitate working memory. Affective words (negative, neutral, positive) were used as retro-cues in a working memory task that required participants to remember colors at different spatial locations on a computer screen. Following the cue, a target detection task was used to either shift attention to a different location or keep attention at the same location as the retro-cue. Finally, participants were required to discriminate the cued color from a set of distractors. It was found that negative cues yielded shorter response times (RTs) in the attention-shift condition and longer RTs in the attention-stay condition, compared with neutral and positive cues. The results suggest that negative affective valence may enhance working memory performance (RTs), provided that attention can be disengaged.
先前的研究表明,由于注意力捕获效应,负性信息会损害工作记忆表现。本研究考察了负性效价是否也能促进工作记忆。在需要参与者在计算机屏幕上的不同空间位置记住颜色的工作记忆任务中,使用情感词(消极、中性、积极)作为回溯线索。在提示之后,使用目标检测任务将注意力转移到不同位置或保持与回溯线索相同的位置。最后,要求参与者从一组干扰项中辨别出提示的颜色。结果发现,与中性和积极线索相比,负性线索在注意转移条件下产生更短的反应时(RT),而在注意保持条件下产生更长的 RT。结果表明,负性情绪效价可能会增强工作记忆表现(RT),前提是注意力可以脱离。
