积极情绪对言语和空间工作记忆的选择性影响

A Research of the Selective Effects of Positive Emotion on Verbal and Spatial Working Memory

目的:探究积极情绪对言语和空间工作记忆的选择性影响。方法:采用修正的延迟样本匹配任务,以国际情绪图片系统中的积极和中性图片为情绪刺激,考察积极情绪对两种不同工作记忆系统的影响。结果:积极情绪条件下,高、低负荷的言语工作记忆任务上的反应时都加快,而低负荷空间工作记忆任务上的反应时变慢,且这种分离不是由积极情绪的唤醒度差异造成。结论:积极情绪促进言语工作记忆,但损害了低负荷的空间工作记忆。

Objective： To explore the different effects of positive emotion on spatial and verbal working memory system.Methods： We employed the delayed match to sample（DMS） paradigm with the positive and neutral pictures from the International Affective Picture System（IAPS） in healthy undergraduates.Results： The results of Experiment one revealed that the reaction time became shorter for high and low load verbal working memory task,and the reaction time became longer for low load spatial working memory in the condition of positive emotion.The second experiment excluded the possibility that such dissociation was due to the different levels of positive emotional arousal.Conclusion： To some extent,positive emotion facilitates both high and low load verbal working memory,but impairs low load spatial working memory task,not high.
