marginally significantp = 0.06
The interactive effect of valence and electrode zone was significant, [ F (4, 140) = 4.43, p = 0.03, η 2 p = 0.11], indicating that the difference between TiN and TiP is significant in the central-parietal and parietal areas ( p = 0.003, p = 0.002), marginally significant in the central area ( p = 0.06), but not in the frontal and frontal-central areas.
