Behavioral Dynamics of Cognitive and Metacognitive Conflict

Presenter: Jintao Xing

Cognitive conflict has been widely used to investigate cognitive control mechanisms. Recent research extended this to the metacognitive level by defining metacognitive conflict as the inconsistency between external feedback and confidence. The current work investigates interaction between both types of conflict using a modified Simon task, tracking how and whether cognitive and metacognitive conflict jointly shape cognitive performance and confidence. The results revealed significant but independent effects of adaptation to cognitive conflict and adaptation to metacognitive conflict. Model-based analysis further revealed opposite effects of post-decision biased accumulation: biased towards high confidence after incongruent trials and biased towards low confidence after metacognitive conflict trials. Together, these results highlight independent yet parallel mechanisms through which different types of conflict shape decision making. Keywords: Conflict; Confidence; Decision making; Metacognition
