Abstract
The current study was conducted to assess the feasibility of a remote administration of the DalCAB, confirm a preference for eveningness in young adults and morningness in older adults, and see if age-related shifting diurnal rhythm preferences affect attention performance.Of the 62 participants who consented to participate, 26 young adults (18-35 years) and 29 older adults (55-79 years) completed the DalCAB once in the morning (8 AM) and once in the evening (4 PM) and took the Morningness-Eveningness Questionnaire (MEQ) to assess diurnal preference.With a 90% completion rate and highly acceptable System Usability Scale scores we conclude that remote administration of the DalCAB is feasible.We found a significant relationship between age and MEQ type with an increased preference for morningness with age.Current data suggest that both older and younger adults were able to perform similarly on the DalCAB at any time during the normal workday.

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
