The role of consciousness in conﬂict adaptation has been a topic of much debate. The purpose of the current study was to investigate the neural correlates of block-wise conﬂict adaptations elicited by conscious and unconscious conﬂicting stimuli in a meta-contrast masked priming task.
Event-related potentials (ERPs) were recorded while individuals responded to prime-target pairs in mostly congruent (80% congruent trials, 20% incongruent trials) and mostly incongruent blocks of trials (20% congruent trials, 80% incongruent trials). Mean response times and error rates revealed that the conﬂict effect (incongruent trials-congruent trials) was reduced in mostly incongruent blocks relative to mostly congruent blocks. Furthermore, conﬂict related ERP signals (the amplitude
difference between congruent and incongruent trials) for three ERP components (early occipito-parietal negativity, the fronto-central N2 and the centro-parietal P3) were attenuated in mostly incongruent blocks compared to mostly congruent blocks, reﬂecting block-wise adaptation to the frequency of conﬂict. The conﬂict-related frontal N2 component differentiated most strongly between visibility conditions. These results further specify the electrophysiological correlates of block-wise strategic adaptations to consciously and unconsciously elicited conﬂict.
