Feedback-Related Negativity at the Feedback Evaluation Stage During the feedback evaluation stage, the ANOVA results showed that the main effect of consistency was marginally significant [ F (1,18) = 4.193, p = 0.055, η 2 = 0.189] and the main effect of feedback valence was significant [ F (1,18) = 10.956, p = 0.004, η 2 = 0.378].
