We investigated the effects of repetition priming on indices conflict adaptation. Event-related potentials (ERPs) were obtained while 210 healthy individuals (111 female, 99 male) completed an Eriksen flanker task. Error rates, response times (RTs), and N2 P3 amplitudes showed significant adaptation (i.e., previous-trial congruencies influenced current-trial measures). After omitting trials with stimulus-response repetitions, RTs did not index adaptation, but show switching effects; error rates remained sensitive to positively correlated RTs. only incongruent following congruent after excluding repetitions. Results indicate that neural monitoring remain reliably associated in absence RT adjustments upon omission effects.
