摘　　要：情绪性注意是一种对具有情绪意义的刺激进行选择和加工的注意。由于刺激的情绪效价能调制人脑的感知和注意系统,因而,与对中性刺激的注意相比,情绪性注意的神经机制更加复杂。较早的研究显示,杏仁核对感知皮层的调制对情绪性注意起关键作用。近期的证据表明,杏仁核对注意功能网络的调制可能是其重要的神经机制。本文梳理了相关领域的研究证据,主要强调情绪性刺激对注意的警觉、定向和执行控制网络的调制,发现情绪性注意加工的认知神经机制可能涉及一个以杏仁核为核心的多重功能网络。Emotional attention can be defined as a kind of attention that selects and processes sensory stimuli with emotional significance. Because the brain’s sensory and attentional system can be modulated by the emotional valence, attention to emotional stimuli is endowed with a more complicated mechanism than neutral stimuli. Previous studies claimed that the key mechanism is the amygdala’s modulation on the sensory system. Recent evidences showed that the amygdala’s modulation on the attentional networks is also very important. We reviewed recent researches on the relevant area, and emphasized the influence of emotion on the alerting, orienting and executive networks, finding that the neural mechanisms of emotional attention is involved in a multiple function network with the core of amygdala.
