The frontally located P160 component is elicited by facial stimuli. The P160 is larger for facial stimuli vs. control stimuli (Herrmann et al., 2002, Ashley et al., 2004), and has been shown to be influenced by the emotion of the facial stimulus (Eimer and Holmes, 2007). The P160 is also elicited by unattended facial stimuli (Holmes et al., 2006). Two recent studies comparing men and women found P160 amplitude to be larger in women (Proverbio et al., 2006, Suyama et al., 2008) with P160 earlier in women in one of the studies (Suyama et al., 2008).
