决策信心的认知机制与神经基础

Cognitive and Neural Mechanisms of Decision-making Confidence

决策信心是指在进行判断或决策时,个体对其决策最优性或正确性的信心程度。决策信心的单过程理论认为决策与信心评估是并行的同一加工过程;而决策后理论认为决策和信心评估是串行的两个加工过程。决策信心存在两种典型的偏差效应:过分自信和信心不足。决策信心的神经机制研究指出,信心评估可能是决策过程中最基本并且普遍存在的一个成分;对决策信心评估敏感的脑区包括扣带回、背外侧前额叶和顶上小叶等。未来研究应该在决策信心产生的机制、信心与决策如何交互的心理及神经机制等领域展开大量研究。

Decision-making Confidence is the degree of confidence of the optimization or correctness its decision when one making judgments or decisions.The single-process theories of decision-making confidence suggest decision-making and assessment of confidence is the same parallel process;while the postdecisional theories consider that decision-making and assessment of confidence are two serial different process.The decision-making confidence has two kinds of typical bias effect：overconfidence and lack of confidence.Neural mechanisms of decision-making confidence revealed that the assessment of confidence may be the most basic and pervasive component of decision-making;functional brain areas involved in assessment of confidence include Cingulate gyrus,Dorsolateral prefrontal cortex and Superior parietal and so on.Studies in the future should increase researches of the psychological and neural mechanism on the interaction of confidence and decision-making.
