N170 Amplitude The ANOVA for N170 peak amplitude ( Table 4 and Figure 5 ) also showed a significant main effect of emotion types [ F (1,44)=6.62, p =0.014, η 2 =0.13] and a marginally significant four-way interaction among emotion type, cue validity, electrode location, and age [ F (1,44)=3.93, p =0.054, η 2 =0.08].
