Subclaims¶

q3 i? In the MT group only, the P200 even-minus-odd effect correlated with memory increment (r = 0.66, p = 0.009) and the F3 theta effect did so marginally (r = 0.52, p = 0.04); neither correlated in the NC group. → Yafeng Pan 2023

q3 · i? · causal · r1

Pearson correlations between neural odd-even effects (post-training) and memory increment (d'post − d'pre): MT group r = 0.66, p = 0.009 (P200) and r = 0.52, p = 0.04 (F3 theta); NC group r = 0.13 and r = 0.06. A Fisher's z test showed the MT P200 correlation was "signi ficantly larger than that in NC, z = 1.72, p = 0.04".

"We found a signi ficant correlation between the P200 effect (averaged over all signi ficant electrodes) and memory increment in the MT group only ( r = 0.66, p = 0.009,"
