(a) Main effect of congruency seen between 250 and 350 ms at posterior sites P9/P10, with more negative amplitudes for congruent than incongruent conditions (group grand average displayed). (b) This effect was seen polarity-reversed at frontal and centro-parietal sites (here exemplified by Fz and CPz electrodes), where amplitudes were now more positive for congruent than incongruent conditions. (c) The topographic map illustrates the distribution of the congruency effect (congruent minus incongruent), averaged between 250 and 350 ms, and (d) the green map shows the two electrode clusters focused on the statistical analyses for the late positive potential (LPP)-like components (frontal and centro-parietal clusters).
