Abstract
This cross-sectional study investigated the joint associations of moderate-to-vigorous physical activity (MVPA) and smartphone screen time (ST) with inhibitory control performance in 210 Brazilian school adolescents. MVPA level was assessed using the Global School-based Student Health Survey questionnaire, categorized as inactive (<60 min/day) or active (60+ min/day). Weekly ST was measured using participants’ smartphones, categorized as low (<7 h/day) or high (7+ h/day) based on the median. Participants were divided into four groups: inactive + high ST, inactive + low ST, active + high ST, and active + low ST. Inhibitory control performance was evaluated using the Flanker task, measuring reaction time and accuracy in congruent/incongruent stimulus. A generalized multiple gamma model revealed that only the inactive + high ST group showed a higher reaction time in the incongruent phase compared to the active + low ST group (β = 41.1 ms; 95% CI 2.3, 79.9; p = .038). No differences were found in the accuracy (p > .05). In conclusion, physical inactivity combined with high smartphone ST is associated with poorer inhibitory control performance in school adolescents.

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
