Abstract: 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.
