Mean amplitude values of the ERPs in target and standard conditions at the latencies of the P2f, P2p, P3a, P3b and SW components (a, b, c, d and e, respectively). FSP and SN must be interpreted as the difference waves of the target minus standard conditions in (a) and (b). The represented amplitudes correspond to the average voltage amplitude in the selected electrodes for each component (see the Methods section). T Target, S Standard
