摘要
情绪加工领域是老化过程中少有的受老化影响不明显的认知领域。国内外研究表明,情绪加工中年龄差异明显的脑区主要分布在前额皮层,尤其是内侧前额叶(mPFC)和边缘系统中的前部扣带回ACC、杏仁核和海马等。目前研究一致的发现是相比年轻人,老年人在前额激活更多,而在杏仁核等激活降低。在情绪效价加工方面,存在一种关于年龄的正性情绪偏向,但其认知神经机制尚不十分清楚,此外,研究表明在非限制性加工中,老化效应更加明显。本文介绍了两种关于情绪加工中老化效应的理论、模型,分别是社会情绪选择理论(SST)和情绪方面额叶-杏仁核的年龄差异模式,希望能够对情绪加工中的年龄差异做出解释。
The emotional processing is a cognitive field which is not significantly affected by aging. Domestic and foreign studies show that the brain regions exhibited the significant age-related difference during emotion processing are mainly distributed in the prefrontal cortex, especially the medial prefrontal cortex (mPFC), and the anterior cingulate cortex (ACC), the amygdala and the hippocampus within the limbic system. The existing studies come into being some consistent findings that compared with young people, older adults tend to activate more on the prefrontal regions, but less in the amygdala. In terms of emotion valence processing, there is an age-related positive effect which is accepted by the emotion domain, but the underlying neural mechanism is still not that clear. In addition, some studies have shown that in these tasks, the way the emotional stimuli processed is unconstrained;the aging effect is likely to be more apparent. This review introduces a theory and a model about the aging effect in emotion processing, the Socioemotional Selectivity Theory (SST) and Fronto-amygdalar Age-related Differences in Emotion (FADE) model, respectively, with the hope to explain the age-related differences in emotion processing.
