Our new study
in collaboration with Paul Roux
from Versailles Hospital shows that confidence in perceptual decision-making is preserved in schizophrenia. Against our pre-registered hypotheses
, we found that individuals with schizophrenia had similar metacognitive performance as healthy matched controls, despite a weaker association between confidence and trajectory tracking during task execution among patients. Michael Pereira
managed to reproduce some of these results with a bounded evidence accumulation model, which further showed that the two groups were characterized by similar decision-making processes.
