Grand averages of P1, N1 and P3 waveforms timelocked to the stimuli. A: P1 and N1 waveforms estimated at PO7 and PO8 for the first four learning blocks (S_1-4), the last four learning blocks (S_7-10) and all learning blocks (S_1-10). B: P3 waveforms estimated at Pz for the first four learning blocks (S_1-4), the last four learning blocks (S_7-10) and all learning blocks (S_1-10).
