Subclaims¶

q2 i2 Reconstructed models without the other operation as covariate remained significant and involved left IPS (subtraction, r = 0.3231) and right AG (multiplication, r = 0.3304). → Zhang 2024

Evidence¶

Zhang 2024¶

Zhang, D., Xie, Y., Wang, L. & Zhou, K. (2024). Structural and transcriptional signatures of arithmetic abilities in children. npj Science of Learning 9, 58. https://doi.org/10.1038/s41539-024-00270-6

q2 · i2 · associational · r2

Control-variable comparison analysis reconstructing each predictive model without the other operation as covariate; the subtraction model "involved the left IPS" with r = 0.3231, consistent with counting-based procedures.

"We found that the subtrac- tion predictive model had significant prediction performance (r = 0.3231; the first permutation testing approach:Pperm = 0.0001; the second permutation testing approach:Pperm = 0.007) and involved the left IPS."

q2 · i2 · associational · r2

The reconstructed multiplication model "involved the right AG" with r = 0.3304, consistent with fact retrieval; the two control models shared 9 brain regions.

"The multiplication predictive model had significant prediction performance (r = 0.3304; the first permutation testing approach: Pperm = 0.0001; the second permutation testing approach:Pperm = 0.006) and involved the right AG (Supplementary Fig. 2)."

Discussion¶

Related Claims¶

• Children with dyscalculia show altered parietal activation during number processing, including compensatory greater activation in the left IPS, but the evidence base is too small for reliable conclusions — related
• Individual records revealed contrasting specific disabilities within the same pupil across arithmetic operations — related
• Structural patterns of arithmetic ability correlate with transcriptional profiles enriched for transmembrane transport (subtraction) and synaptic signaling (multiplication)
