At midline leads (Cz/FCz), the 2 face type × 2 group × 2 attachment × 3 lead repeated measures ANOVA solely revealed a highly significant main effect for lead, F (1, 33) = 12.12, p = 0.001, η p 2 = 0.27, with Nc amplitude responses being more negative at FCz ( M = −6.84, SE = 0.65) than Cz ( M = −5.33, SE = 0.68).
