Neuropsychological Performance, IQ, Personality, and Grades in a Longitudinal Grade-School Male Sample
Bibliographic record
Abstract
This study assessed the statistical relationship between neuropsychological performance, IQ and personality test results and school grades in a longitudinal sample of adolescent males. One-hundred and forty-eight boys completed six years of WISC-R short forms (Block Design and Vocabulary) and provided six years of math and language grades and grade failure data while in elementary school. In junior high school, the same boys completed an extensive neuropsychological test battery and the NEO-PI-R, a standard big five personality trait measure. Neuropsychological test scores were more powerfully associated with grades than were IQ scores, despite their later and single administration. In addition, hierarchical regression analysis demonstrated that three of four neuropsychological test score factors (Verbal Learning, Executive Function, and Tactile Laterality improved the statistical association with six-year averaged failure-weighted grades over and above IQ (averaged Vocabulary and Block Design). NEO-PI-R Agreeableness was significantly and positively related to grades, over and above both IQ and neuropsychological function.

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.
