q3 i? In the MT group, the Position × Session interaction was significant: post-training P200 amplitude was greater for even-position (3.08 ± 0.96 μV) than odd-position digits (1.34 ± 0.80 μV); the NC group showed no such effect. → Yafeng Pan 2023

q3 · i? · causal · r1

Planned repeated-measures ANOVAs (Position, Session, Area) on P200 amplitude in the MT group (n = 16) showed a significant Position × Session interaction; post-hoc tests confirmed "greater P200 amplitude in response to even-position digits (3.08 ± 0.96 μV) compared to odd-position digits (1.34 ± 0.80 μV)". The NC group showed no such effect (all ps > 0.41).

"we found the interaction effect of Position × Session, F (1, 15) = 3.79, p < 0.05, η2 partial = 0.17: the post-training session showed greater P200 amplitude in response to even-position digits"
