Computational Models of Interoception in Psychiatric Disorders

Using Bayesian active inference frameworks, we model how individuals with depression, anxiety, eating, and substance use disorders fail to adaptively regulate interoceptive precision estimates. This transdiagnostic approach reveals shared computational mechanisms across psychiatric conditions.

Methods Used

Key Findings

Transdiagnostic failure to adapt interoceptive precision confirmed across anxiety, depression, eating, and substance use disorders (PLoS Comput Biol 2020; replicated in 2024, Biological Psychology). An Annual Review of Clinical Psychology paper provides the theoretical framework.
