My notes
- The authors describe a Bayesian account of OCD. Inability to rely on top-down predictions (hands are clean after washing, but no sensory input confirms it for me) makes OCD patients over-reliant on habits.
- Compulsions can go from goal-directed to habitual over time.
Compulsions can be both attempts to reduce overestimated threat, and expressions of inflexible habits. Both proximal causes stem from the same core impairment (unreliable predictive models) and differentiating them becomes a question of context (e.g., some contexts encourage habit formation more than others), rather than a theoretical stance.
