“…The SPN amplitude was modulated by the relevance of the feedback, main effect of error feedback type, F(2, 68) = 24.6, p < .001, ηp 2 = 0.42, being greater during Final reversal errors (FRE) when compared to Spurious negative and Reversal trials. In agreement with previous studies (Masaki et al, 2006;Moris et al, 2013), the SPN increase during motivationally engaging and relevant feedback (in this case, Final reversal errors) was greater during the time window of 200 to 0 ms preceding feedback onset as revealed by the interaction error feedback type x time, F(2, 68) = 11.2, p < .001, ηp 2 = 0.25. A triple interaction error feedback type x time x Group, F(2, 68) = 4.6, p < .05, ηp 2 = 0.12, further showed that during the 200 ms preceding feedback presentation the enhancement of the SPN amplitude during Final reversal errors was stronger on the High ET group.…”
