Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? A cluster-randomized classroom trial reported selective enhancement of mathematics-specific inhibitory control with no reliable change on the Flanker task. → David Moreau 2026

q2 · i? · theoretical · r3

The commentary summarizes Zhang et al. (2026), a "cluster-randomized trial in authentic classroom settings" administering brief pre-class exercise before instruction. The dissociation between a domain-aligned and a domain-general measure is the empirical basis of the argument. No effect sizes are printed here.

"Their central finding was a selective enhancement of mathematics-specific inhibitory control following instruction, alongside no reliable change in performance on a canonical measure of domain-general interference control (Flanker task)."

Discussion¶

Learner Variables¶

Executive Function — outcome: instruction changes it

Null Flanker effects under ecologically realistic exercise constrain claims of broad, generalized enhancement of executive control — a broader claim this one bears on
Flanker task produces congruency effects in reaction time and accuracy in twelve-year-old children — related
Acute exercise significantly improves inhibitory control in children and adolescents with a small effect size (SMD = −0.25) — a broader claim this one bears on
A 10-minute bout of moderate-intensity exercise improves Stroop inhibitory control with increased left dorsolateral prefrontal activation in young adults — related
