Decision confidence is a person’s strength of belief about the optimization or correctness of a prediction, judgment, or choice. It provides a graded scale which allows us to translate internal convictions into suitable actions in the physical world. Simultaneously, decision confidence can affect a variety of cognitive functions: how we learn and improve subsequent actions, and how we justify our choice to others. Previously, many studies were performed based on the single assessment of decision confidence, but it is known to all that individual’s confidence constructed in a dynamic way. According to the Two-Stage Dynamic Signal Detection Model (2DSD), a judge doesn’t simply shut down the information accumulation process after making a choice but continues to accumulate information to make a confidence rating. In other words, the confidence rating is a function of the information collected at the time of the choice plus the information collected after making a choice. From this point of view, feedback information is vital to the dynamic construction of decision confidence after a decision was made. Several studies have indicated that individual’s confidence rating will increase after receiving supportive feedback information, and individual’s confidence rating will decrease after receiving opposed feedback information. However, it is still inconclusive how the presentation order of feedback influenced the dynamic construction of decision confidence when different types of feedback presented successively. In the present study, sensory discrimination task was used to probe into this issue.
