Psychiatric Symptom Dimensions Are Associated With Dissociable Shifts in Metacognition but Not Task Performance.

ABSTRACT:

Background

Distortions in metacognition-the ability to reflect on and control other cognitive processes-are thought to be characteristic of poor mental health. However, it remains unknown whether such shifts in self-evaluation are due to specific alterations in metacognition and/or a downstream consequence of changes in decision-making processes.

Methods

Using perceptual decision making as a model system, we employed a computational psychiatry approach to relate parameters governing both decision formation and metacognitive evaluation to self-reported transdiagnostic symptom dimensions in a large general population sample (N = 995).

Results

Variability in psychopathology was unrelated to either speed or accuracy of decision formation. In contrast, leveraging a dimensi
