Abstract :
Electroencephalography (EEG) studies have largely reported the P300 Event Related Potential (ERP) elicited by target stimulus processing compared to non-target stimulus. These studies used constrain experimental paradigms during which participants did not move their eyes. However, during more ecological paradigms where participants can move their eyes, the P300 potential might be more difficult to identify due to the overlapped potentials elicited by consecutive ocular fixations. In this study, we use the xDawn algorithm for denoising 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.
