showed a trendp = 0.088
A repeated measures ANOVA with these two factors showed a trend toward a main effect of accuracy in the next round [ F (1, 22) = 3.19, p = 0.088, η p 2 = 0.127] with larger P300 amplitudes for negative feedback items that were answered correctly in the following round ( M = 5.52, SD = 3.75) compared to when errors were repeated ( M = 4.31, SD = 3.37).
