Abstract:

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.

Key words: negative bias, attention bias, memory bias, neural mechanism
