Abstract
Some psychotropic medications frequently prescribed in schizophrenia, especially agents that contain anticholinergic properties, have adverse effects on learning and memory. Given the impact of memory on both functional and symptomatic outcome in schizophrenia, it is important to determine if patients suffer from medication-related memory impairment. This study provides a statistical methodology for identifying medication-related changes in memory functioning. Reliable change estimates were determined for Rey Auditory Verbal Learning Test performance in 38 inpatients with schizophrenia. When an 80% confidence criterion was applied, improvement or decline of 12 words in the total score (sum score: Trials 1-5) cannot be attributed to measurement error. These findings should help clinicians better understand cognitive side effects and facilitate decision making regarding changes to individual patient's psychopharmacotherapy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
