Abstract
BACKGROUND: Aging is characterized by cognitive changes in specific domains, such as declines in memory and executive functions. Given the world's aging population, it is important to identify and evaluate strategies that promote healthy cognitive aging. Besides exercise, computerized cognitive training (CCT) is a promising approach to promote cognitive function. Moreover, a single bout of exercise immediately prior to CCT may provide additional cognitive benefits. METHODS: An 8-week proof-of-concept randomized controlled trial to investigate the effect of a commercial CCT intervention, alone and when preceded by exercise, on cognitive function. Participants (124; aged 65-85 years) performed 8 weeks of: (i) Group-based CCT (Fit Brains) 3×/week for 1 hour plus 3×/week home-based training; (ii) Group-based CCT preceded by exercise (Ex-CCT) 3×/week for 1 hour plus 3×/week home-based training (exercise+CCT); or (iii) Group-based balanced and toned (BAT) classes 3×/week for 1 hour (control). Memory was assessed by the Rey Auditory Verbal Learning Test. Executive functions were assessed using the: (i) Stroop Test, (ii) Trail Making Tests (TMT), (iii) Flanker Test, and (iv) Dimensional Change Card Sort Test (DCCS). RESULTS: At trial completion, there were no significant between-group differences in memory (p > .05). However, compared with BAT, CCT, and Ex-CCT significantly improved Stroop performance (-10.72, 95% confidence interval [CI]: -16.53, -4.91; -7.95, 95% CI: -13.77, -2.13, respectively). Moreover, Ex-CCT significantly improved the performance on TMT (-13.65, 95% CI: -26.09, -1.22), the Flanker Test (6.72, 95% CI: 2.55, 10.88), and the DCCS Test (6.75, 95% CI: 0.99, 12.50). CONCLUSION: An 8-week CCT program may promote executive functions in older adults and combining it with a bout of exercise may provide broader benefits.

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
