All grown up: Computational theories of psychosis, complexity, and progress.
Bibliographic record
Abstract
The theme of this special issue of the Journal of Abnormal Psychology is on predictive processing and how it can improve our fundamental understanding of neuropsychiatric disorders. Several articles focus on psychosis and demonstrate how the field of computational psychosis research has evolved and matured in recent years through the application of predictive processing theory. These articles suggest that whereas the computational mechanisms underlying psychosis may be complex, careful empirical and theoretical work-using more sophisticated models-can bridge gaps between previous results that appeared to be at odds while providing more explanatory power. There is a particular focus on processing hierarchies; defining which priors are maladaptive and at what stage of illness they become so; and finding compelling neurobiological correlates of computational processes. These articles provide a blueprint for future empirical work. This work-that is licensed theoretically by predictive processing-may improve our understanding of psychosis and its treatment and open new avenues for biomarker and therapeutic development.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
