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? Whole-brain t tests found no gender differences in neural maturity, and Schuirmann's Test of Equivalence found girls and boys statistically equivalent throughout the brain. → Kersey 2019

q3 · i? · associational · r2
Whole-brain fMRI analysis of 104 children (55 girls) aged 3–10 during natural viewing of mathematics education videos, using intersubject correlations to adult baselines. The authors report "statistically equivalent levels of neural maturity throughout the brain"; no mean differences survived correction and the equivalence tests were significant.
"In fact, girls and boys showed statistically equivalent levels of neural maturity throughout the brain (Fig. 1a, light purple; minimum t(102) ≥ 2.36, maximum one-sided p ≤ 0.01)"
Discussion¶
Related Claims¶
- Bayesian analysis finds substantial evidence for gender similarities in neural maturity in most of the brain, with fewer than 1% of voxels supporting gender differences — a narrower finding that bears on this claim
- Within the number processing network, girls and boys show statistical equivalence in neural maturity and no variance differences — a narrower finding that bears on this claim
- Children engaged number-selective neural responses in the intraparietal sulci during educational videos, and boys and girls did so equally — related
- Math ability predicts neural maturity in the same brain regions for boys and girls, with no gender-by-ability interaction — related
- In one small right posterior parietal region, girls showed greater neural variance than boys at equal mean activation — related
- Whole-brain neural similarity between children is the same for same-gender and different-gender pairs — related
