The relative θ power MANOVA shows that the group, stimulus and group × stimulus effects are all significant. The significant group effect (F(5,90) = 2.344; p = 0.048) accounts for 11.5% of the variance, with the LTAAs showing greater positive log ratios (i.e. larger ERS) than the NACs on average across all three stimuli, with the largest effects being at frontal electrode sites.
