焦慮與風險決策的腦機制之間存在著高度重疊的部分(如:前額葉、杏仁核、前扣帶回、紋狀體、腦島等),而且重疊的這部分腦機制也被卷入到了焦慮影響風險決策的過程中。本文通過綜述這些腦區在二者關系間的功能及其對應的網絡結構,試圖探索了焦慮影響風險決策的神經機制,并借用風險敏感理論與認知資源理論,從情緒與認知雙加工角度對此進行了闡述。未來對二者關系的研究可考慮從遺傳基因、神經遞質以及發展性等角度進行探索。

The neural mechanism underlying anxiety and risk-making decisions has a high degree of overlapping(e.g.,amygdala,striatum,cingulate gyrus,insula,and prefrontal cortex),and these overlapping parts involve the process of how anxiety impacts the risk-making decision.This paper described and discussed the neural structure and the function of these brain regions with respect to the relationships between anxiety and risk-making decision,in an effort to explore their underlying neural mechanism.Moreover,based on the theoretical framework of risk sensitivity and cognitive resources,this paper also explained this relationship from the perspective of emotional and cognitive double processing.Finally,we suggest that future studies may explore the relationship between anxiety and risk decision-making from perspectives of genetics,neurotransmitters,or development.
