Decisions are accompanied by a feeling of confidence, i.e. the subjective estimate of the probability of being correct. High confidence accuracy has been shown to be critical for making advantageous choices and adaptive behaviour. Indeed, if one assigns too much credit to a poorly informed decision or exhibits too little trust in a good decision, this can lead to disadvantageous decision-making. In extremis, inaccuracy in confidence might lead to continuously enacting the same behaviour regardless of the outcome, as observed in compulsive disorders, such as gambling addiction (GD) and obsessive-compulsive disorders (OCD). In my talk, I will present data from experiments that seek to understand how incentive motivation can impact confidence estimation and associated brain functions. These tasks further allow us to characterize confidence biases in GD and OCD patients. Moreover, I will discuss how feelings of confidence about trial and task performances are related to higher-order self-beliefs and differ depending on specific symptom clusters.
