q3 · i? · associational · r3

Voxel-based morphometry analysis of six merged structural MRI datasets of children aged 7.5 to 15, with ROI-based linear mixed-effect models. The article reports "a relation between GMV and arithmetic score was only observed in the left IFG" (and left MTG, Table 3/Table 4), with arithmetic coefficients of 0.004 in both ROIs.

"Across all mixed-model analyses, a relation between GMV and arithmetic score was only observed in the left IFG"

Discussion¶

Related Claims¶

• The relation between arithmetic skill and gray matter volume in the left IFG and left MTG remains significant after controlling for reading, vocabulary, verbal and non-verbal IQ — related
• Bayesian analyses provide evidence that arithmetic skill does not relate to gray matter volume in the left angular gyrus, intraparietal sulcus, or hippocampus — related
• Gray matter volume significantly predicts children's multiplication skill in a cross-validated model — related
• Exploratory whole-sample cortical thickness analysis found no relation between arithmetic score and cortical thickness — related
