Abstract
An increase in Stroop effects with age is often interpreted as reflecting reductions in selective attention, or alternatively, cognitive slowing with age. In a cross-lab and a cross-sectional analysis, we linked sensory losses to Stroop declines. Specifically, we found that the latency difference, or dimensional imbalance, between reading and naming the font color of color-neutral words increased with age. A cross-sectional analysis revealed that this dimensional imbalance can both mediate the effects of age on Stroop effects, and contribute to Stroop after controlling for age effects. We conclude that age-related changes in color perception contribute to and may mediate age-related changes in Stroop.

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
