Though emotion conveys memory benefits, it does not enhance memory equally for all aspects of an experience nor for all types of emotional events. In this review, I outline the behavioral evidence for arousal's focal enhancements of memory and describe the neural processes that may support those focal enhancements. I also present behavioral evidence to suggest that these focal enhancements occur more often for negative experiences than for positive ones. This effect of valence appears to arise because of valence-dependent effects on the neural processes recruited during episodic encoding and retrieval, with negative affect associated with increased engagement of sensory processes and positive affect leading to enhanced recruitment of conceptual processes.
尽管情绪能带来记忆方面的益处,但它并非对经历的所有方面或所有类型的情绪事件都能同等程度地增强记忆。在这篇综述中,我概述了唤醒对记忆的聚焦增强作用的行为证据,并描述了可能支持这些聚焦增强作用的神经过程。我还展示了行为证据,表明这些聚焦增强作用在负面经历中比在正面经历中更常出现。效价的这种影响似乎是由于效价对情景编码和检索过程中所涉及的神经过程的依赖性影响而产生的,负面情绪与感觉过程参与度的增加相关联,而正面情绪则导致概念过程的参与度增强。
