PASSIVE EVENT-RELATED POTENTIALS BY A SINGLE TONE IN PERSONALITY DISORDERS
Bibliographic record
Abstract
A cerebral P3 potential (passive P3) in response to a single tone shares similar morphology to the classical P3 elicited in the active “oddball” paradigm, but reflects passive attention. As patients with schizotypal, antisocial, and borderline personality disorders show reduced amplitude and prolonged latency of classical P3, it is reasonable to expect that these patients might show an abnormal passive P3. We tested whether the single tone elicited event-related potentials (ERPs) in 205 patients with personality disorders and in 30 healthy volunteers. Their Axis I symptoms of depression and anxiety were measured by Zung's Self-rating Depression Scale and Self-rating Anxiety Scale (1965, 1971). Both schizoid and paranoid groups showed significantly reduced P3 amplitude. In addition, the schizoid group showed significantly shortened N1 latency and enhanced N2 amplitude. Most patient groups except schizoids scored higher on the Depression or Anxiety scales, or both, but the ERP findings were not correlated with the Axis I symptoms in any given group alone. The abnormal negative components implied a higher vigilance or cortical arousal level in the schizoid patients, while the reduced P3 amplitude indicated a poorer passive attention in both schizoid and paranoid patients.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
