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.
q3 i? A whole-brain regression found math ability predicted neural maturity in IPS, prefrontal cortex, and middle temporal gyrus in both gender groups, and no cortical regions showed significant math-ability-by-gender interactions. → Kersey 2019

q3 · i? · associational · r2
Whole-brain regression entering math ability, gender, and their interaction as predictors of neural maturity in the 104-child fMRI sample. Girls showed r(48) ≥ 0.36 and boys r(45) ≥ 0.37 relations between ability and maturity; the article concludes the relation does not depend on gender.
"No cortical regions showed significant interactions between math ability and gender (t(93) ≤ 2.63, threshold: voxel-wise p ≤ 0.01, cluster corrected to p < 0.05, threshold = 110 voxels), indicating that the relation between math ability and neural maturity does not depend on gender."
Discussion¶
Learner Variables¶
- Gender — moderator: an instructional effect differs by group
