Computational Psychiatry Tutorials
A guided path through the computational models behind psychosis care: how the brain predicts, where prediction fails, and which treatments target each mechanism.
Foundations
Start with the core model
Computational Psychiatry: the founding framework
Why California OnTrack was built from the bottom up on the Bayesian brain, precision weighting, and aberrant salience. Start here.
Open tutorialGenesis of Psychosis
How prediction errors, priors, and belief updating give rise to delusion formation, with an interactive beads task.
Open tutorialMechanisms
How specific mechanisms fail
Jumping to Conclusions
The hasty data-gathering bias: how limited evidence sampling produces overconfident conclusions, and how it is measured.
Open tutorialRestoring Agency in Schizophrenia
Corollary discharge, N1 suppression, and intentional binding: how self-authorship collapses and how it is rebuilt.
Open tutorialDysexecutive Syndrome (DES)
The supervisory attentional system explained, with a simulator showing how executive control breaks down.
Open tutorialComputational Psychiatry of Delusions
Bayesian inference, predictive coding, and hierarchical psychopathology behind fixed false beliefs, with an interactive simulator.
Open tutorialAuditory Verbal Hallucinations
Why voices feel external: strong priors, weak sensory precision, and failures of self-monitoring in the auditory hierarchy.
Open tutorialFormal Thought Disorder
Semantic network dynamics, speech graph metrics, and the computational signatures of disorganized thought.
Open tutorialThe Architecture of Referential Ideation
Ideas versus delusions of reference: aberrant precision, pseudo-social inference, and drift-diffusion decision dynamics.
Open tutorialLoss of Agency in Schizophrenia
Efference copy, sensory attenuation, and how the feeling and judgment of agency come apart under active inference.
Open tutorialAnhedonia & Apathy
Reinforcement learning, effort-based decision making, average reward rate, and vigor: deconstructing negative symptoms.
Open tutorialPareidolia & Pseudohallucinations
Hyper-precise priors, neuromodulatory gain, and reality monitoring: why ambiguous noise becomes faces and voices, with insight preserved or lost.
Open tutorialApplied
From theory to treatment
AI-Associated Psychosis
A computational account of how generative AI acts on pre-existing vulnerability: aberrant salience, circular inference, hypermentalizing.
Open tutorialArchitecture of Cannabis-Induced Psychosis
How cannabinoid signaling perturbs precision weighting and dopaminergic salience along the path to psychosis.
Open tutorialMetacognitive Training (MCT)
Turning computational insight into treatment: targeting overconfidence in errors and hasty causal attribution.
Open tutorialSchizophrenia Simulations
Interactive simulations that make altered perception, salience, and thought disturbance experientially concrete.
Open tutorialAmphetamine-Induced Psychosis
Dopamine sensitization, precision weighting, jumping to conclusions, dose thresholds, and transition to schizophrenia, with an interactive Bayes simulator.
