The metacognitive performance will be primarily analyzed with binomial mixed-effects models between accuracy and confidence, with group (patient vs. control) and several covariates (premorbid and current IQ, depression and executive performance with planning and working memory) as between-subject factors. Regression slope will be taken as an indicator of metacognitive performance and asymptotes as a marker of confidence bias, i.e. the tendency to report high or low confidence ratings independent of task performance. Likelihood ratio tests will assess significance.
