Abstract
Adult cognitive age differences in the Wechsler Adult Intelligence Scale—III Canadian normative data were curvilinear for most scales and for the Verbal Comprehension (VC), Perceptual Organization (PO), and Working Memory (WM) factors. These showed stable or increasing scores in early adulthood followed by decreasing scores, necessitating a nonlinear (continuous parameter estimation) approach to modeling adult age differences. Means were as high as or higher than the 18-year-olds until 60 years for PO and 70 years for WM and VC. As the means showed no interpretable differences across 20 to 30 years of adult cohorts, no one year can be identified as the highest scoring. “What If” analyses correcting for possible Flynn effects and for the hypothesis that changes in Processing Speed may underlie some of the age differences suggest that further testing of these two effects is a necessary prerequisite to advancing our understanding of adult age differences.

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
