There was a main effect of group on P160 latency (Figure 6)-it was delayed in the LTAA compared to NAC, collapsed across tasks (F(1, 94) = 20.58, p < 0.001) (Figure 7). P160 amplitude did not differ between LTAA and NAC. There was a noticeable peak at P300 (Figure 2), and the latency difference (P300–P160) was examined. ANOVA results were not significant, indicating that any P300 latency effects were a direct consequence of P160 latency effects (Table 4).
