q3 i? Repeated-measures ANOVA revealed no main effect of noise condition on alpha or beta power. → Levy 2025

q3 · i? · causal · r2

The same spectral analysis (n=32) found no significant main effect of noise condition on alpha or beta power; no effect size printed. The authors call this replicated null noteworthy.

"Repeated-measured ANOVA revealed no main effect of noise condition in either band [Alpha -power: F(2,31)=1.166, p=0.318 ; Beta -power: F(2,31)=1, p=0.373]."
