  1. SDs are shown in brackets. The latency values are expressed in milliseconds and the amplitude values in μVolts. The time-windows used to compute the latency and amplitude values were the following respectively for adults and children: 50–150 ms and 100–200 ms for the N1, 200–400 ms and 300–550 for the N2, 250–650 ms and 400–1100 ms for the P3; and 550–1300 for the LPC in children. C: congruent; I: incongruent.
