The purpose of this study was to investigate the effect feedback types and meta-cognitive ability on syllogistic reasoning task. To do so, we examined whether the inference accuracy and the amount of the belief-bias were differently affected by positive and negative feedbacks. We also examined whether meta-cognitive ability mediates the effect of feedback types on reasoning. The participants were informed that they would receive incentives or penalties based on the accuracy of the syllogistic reasoning performances. As results, high meta-cognition group showed better inference accuracy and low belief-bias in both of positive and negative feedback conditions. Mid meta-cognition group showed increased belief-bias when they received positive feedbacks while low meta-cognition group showed increased belief-bias in negative feedback condition. The results of the current study suggest that meta-cognitive ability mediates the effect of the feedback types.
