Table 1.

Time windows used for the statistical analysis of N2 and P3 component latency and amplitude on Correction Rejection (CR) trials, Hit trials and difference waves (CRs minus Hits), computed separately for each age group and task-load condition.

For both age groups, ERPs for Hit trials produced no apparent P3 component (as P3 is often associated with rare events) thus we used the time window encompassing the P3 for CRs to compute the amplitude and latency statistics for Hits.
