The Ne in the present study was maximal at Cz; the amplitude difference between ERPs to errors and to correct trials tested at this electrode (where the Ne was largest) was highly significant, F (1,14) = 129.9, p < .001, and also showed a trend for an interaction between group, session, and correctness, F (1,14) = 3.8, p = .073.
