Table 1.
Event-related brain potential latencies and statistics. The first column indicates the time window of analysis; P200/P300 and N200 latencies correspond to the times of the most positive and negative amplitudes within the windows, respectively. Mean latencies and standard deviations (sd) are reported in ms for each group. The final column represents the ANOVA results.
