q2 i2 A GMV-based LOOCV predictive model significantly predicted individual differences in multiplication performance (r = 0.2824). → Zhang 2024

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

Same LOOCV predictive-modeling analysis on 130 children; the multiplication model reached "multiplication: r = 0.2824, P = 0.0011" and involved motor, occipital, frontal, temporal and parietal cortex regions with non-zero weights.

"For both the subtraction and multip lication predictive model, the correlation between observed and predicted scores was signi ficant (sub- traction: r = 0.3506, P =4 . 3 2×1 0−6; multiplication: r = 0.2824, P = 0.0011"
