Subclaims¶

q3 i? In the MT group a significant three-way Position × Session × Area interaction was followed by a significant post-training Position × Area interaction, with theta power rising from odd (10 ± 5%) to even-position (24 ± 6%) in the left anterior area. → Yafeng Pan 2023

q3 · i? · causal · r1

Planned three-way repeated-measures ANOVAs on frontal theta power (4–8 Hz, 200–1000 ms) in the MT group revealed a significant three-way interaction; the post-training session showed "a signi ficant increase in theta power from the odd- (10 ± 5 %, percent signal change) to even-position (24 ± 6 %) condition in the left anterior area"; the NC group's ANOVA found no significant results (all ps > 0.09).

"Importantly, there was a signi ficant three-way interac- tion, F (2, 30) = 6.92, p < 0.05, η2 partial = 0.37. Breaking down the ANOVA based on the factor Session revealed an interaction"
