For the N2 latency, all main effects except Group, as well as all interaction effects except Group × Condition and Group × Condition × Region (three way), were found to be significant (Table 3). The evaluation of least-squares means revealed a shorter latency of Go compared to NoGo N2 at all regions. However, age had a significant effect on the outcome (Table 3). This indicates that observed main and interaction effects and differences are not comparable across age for the N2 latencies and hence were not discussed further.
