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? Gray matter volume of the arithmetic network is positively correlated with higher arithmetic skills, and white matter integrity of fronto-parietal and fronto-occipitotemporal tracts is positively associated with arithmetic performance. → Stephan E. Vogel and Bert De Smedt 2021
q2 i? In the absence of longitudinal data it is unknown whether these structural variations precede individual differences in arithmetic development or emerge as a result of them. → Stephan E. Vogel and Bert De Smedt 2021 (2)

Stephan E. Vogel and Bert De Smedt. (2021). Developmental brain dynamics of numerical and arithmetic abilities. npj Science of Learning (2021) 6:22. https://doi.org/10.1038/s41539-021-00099-3
q2 · i? · review · r3
Review synthesis of a small number of structural brain imaging studies: gray matter volume of the arithmetic network "is positively correlated with higher arithmetic skills", and white matter tracts connecting prefrontal with posterior parietal and occipitotemporal cortex show positive associations; no effect sizes are printed.
"The evidence from this work suggests that the gray matter volume of the arithmetic network is positively correlated with higher arithmetic skills 132,133."

q2 · i? · review · r3
The review's stated limitation: the correlations are based on cross-sectional data, so it is unknown whether structural characteristics "are the cause or consequence of arithmetic development"; the review reports this as an open question, not a finding.
"In the absence of longitudinal data, we currently do not know whether these structural variations are the cause or consequence of arithmetic development."
Discussion¶
Related Claims¶
- Screen time is not significantly associated with white matter microstructure (FA, MD) in 10-year-olds, while sports participation is positively associated with FA — reports the opposite
- Prior structural brain-wide association studies of arithmetic skills used small samples (n = 11 to n = 59), risking inflated, hard-to-replicate effects — related
