Dissociating volatility and stochasticity reveals transdiagnostic computational signatures of psychopathology
This study identifies distinct transdiagnostic computational signatures of psychopathology by demonstrating that individuals with internalizing disorders tend to misinterpret environmental noise as volatility (over-updating), while those with externalizing disorders tend to misinterpret volatility as noise (under-updating), revealing that learning deficits in psychopathology are selective failures in distinguishing uncertainty types rather than generalized impairments.
