Electroencephalography (EEG) studies have largely reported the P300 Event Related Potential (ERP) elicitedby target stimulus processing compared to non-target stimulus.These studies used constrain experimental paradigms during which participants did not move their eyes. However, duringmore ecological paradigms where participants can move their eyes, the P300 potential might be more difficult to identify dueto the overlapped potentials elicited by consecutive ocular fixations. In this study, we use the xDawn algorithm fordenoising the overlapped Eye-Fixation Related Potentials (EFRP), and we observe the P300 potential elicited on the first,but also on the consecutive subsequent fixations landed on the target stimuli.
