Influences of reward in the relevant dimension on conflict processing.

<p>(<b>A</b>) Averaged ERP distribution maps of the difference between incongruent and congruent trials (<i>Wi0-Wc</i>) in no-reward trials reveal the incongruency-related negativity (N_inc) over centro-parietal sites followed by the late positivity component (LPC) over parietal sites. (<b>B</b>) The analogous comparison in potential-reward trials revealed that the N_inc and LPC components were replaced by earlier modulations in the centro-parietal and parietal ROIs. Gray-shaded areas indicate significant mean-amplitude differences in the respective ROIs (p-values<.05). (<b>C</b>) ERP waveforms for each condition as well as the respective ERP difference waves are shown for selected ROIs (averaged across channels).
