Evidence¶

Nurit Viesel-Nordmeyer and Jérôme Prado 2023¶

Nurit Viesel-Nordmeyer and Jérôme Prado. (2023). Arithmetic skills are associated with left fronto-temporal gray matter volume in 536 children and adolescents. npj Science of Learning. https://doi.org/10.1038/s41539-023-00201-x

q2 · i? · associational · r2

Exploratory surface-based morphometry analysis using the CAT12 pipeline on the same n = 536 sample with the same covariates as the main VBM analysis. The article reports the analysis "did not show any relation between arithmetic score and CT" at the printed corrected thresholds.

"This analysis did not show any relation between arithmetic score and CT (voxel-level threshold of p ≤ 0.001, cluster-level threshold of p ≤ 0.05, family-wise error corrected for multiple comparisons)."

Discussion¶

Related Claims¶

• In children and adolescents, arithmetic skill is positively related to gray matter volume in the left inferior frontal gyrus and left middle temporal gyrus — related
• Cortical thinning in anterior and superior frontal cortex is associated with better arithmetic achievement across all children — 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
