不同嗅觉情境对情绪面孔再认的影响

The Influence of Different Smell Situation on Mood Face Recognition

采用学习–再认范式,考察茉莉花香与空气两种嗅觉情境对情绪记忆的影响。编码阶段,被试在不同嗅觉情境下对情绪面孔图片效价的评分;测验阶段,要求被试对情绪面孔图片进行再认。结果表明,茉莉花香条件下,被试在编码阶段对情绪面孔图片效价的评分显著更低,在测验阶段对其再认成绩更好、反应时更长,证明了编码特异性假说以及情绪记忆增强效应。本研究探索嗅觉与情绪、记忆三者之间的关系,着眼于嗅觉影响情绪记忆的内在机制。

In this study, we used a learning-recognition paradigm to investigate the effects of two olfactory contexts, jasmine and air, on emotional memory. In the coding phase, participants rated the va-lence of emotional faces under different olfactory conditions. In the test phase, participants’ rec-ognition of emotional faces was investigated. The results showed that in the jasmine scented condition, participants scored significantly lower on the valence of emotional face images in the encoding stage, and had better recognition performance and longer reaction time in the test stage, which proved the encoding specificity hypothesis and the enhancement effect of emotional memory. This study explored the relationship between olfaction, emotion and memory, and focused on the internal mechanism of olfaction influencing emotional memory.
