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? Levene's Test of Variance found one small region of right posterior parietal cortex where girls showed greater variance than boys, but no difference in mean activation. → Kersey 2019

q3 · i? · associational · r2
Whole-brain Levene's variance test across the 104-child fMRI sample. The cluster was small (15 voxels; TAL peak 18, −64, 43; F(1,102) ≥ 6.89) and girls showed more variance at equal neural amplitudes, which did not produce a mean difference.
"Levene's Test of Variance revealed one small region of right posterior parietal cortex where groups differed in variance but not in mean activation, with girls showing greater variance than boys"
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 — related
- Whole-brain neural similarity between children is the same for same-gender and different-gender pairs — related
- Boys and girls show statistically equivalent neural maturity throughout the brain during mathematics video viewing — related
- Boys and girls show equal variability in early mathematical performance across all measured tasks — related
- Children engaged number-selective neural responses in the intraparietal sulci during educational videos, and boys and girls did so equally — related
- Within the number processing network, girls and boys show statistical equivalence in neural maturity and no variance differences — reports the opposite
