负性偏向的神经机制

负性偏向是指负性信息比其他信息得到优先的注意和加工。在负性偏向中注意偏向既是一种自动化的过程也是一种受控制的过程, 杏仁核和眶额皮层在这过程中起着重要作用, 杏仁核调节早期的自动化注意偏向而眶额皮层则控制着自上而下的注意偏向; 负性记忆偏向不仅表现在负性信息得到更深的编码, 还表现在负性信息的再认标准降低。未来应开展负性偏向的皮层?皮层连接、基因、负性偏向的拓展以及负性偏向的干预研究。

The Neural Mechanism of Negative Bias

Negative information compared to other types of information can receive priority attention and processing, which is called negative bias. The present paper had mainly introduced the neural mechanism of negative attention and memory bias. Negative attention bias is not only an automatic process, but also a controlled process. Amygdale moderated automatic processing of early negative bias and orbit-frontal cortex controlled the top-down processing. Negative memory bias not only displayed in deeper encoding of negative information, but also reflected in negative information recognition standard reduction. In the future, we should study cortical-cortical connections, gene, expand and intervention of negative bias.
