“…However, so far, own-age effects on the N170 have not been confirmed for neutral faces (Wiese, Komes, & Schweinberger, 2012;Wiese et al, 2008), suggesting that partly different neural processes may underlie own-age and own-race effects. Instead, both younger and older observers showed higher N170 amplitudes for older than for younger faces Wiese et al, 2008), indicating that structural encoding may be more difficult for older faces, for both older and younger observers. Concerning emotion effects on the N170, the results are mixed: Whereas some studies have shown a modulation by emotion (Batty & Taylor, 2003;Blau, Maurer, Tottenham, & McCandliss, 2007;Krombholz, Schaefer, & Boucsein, 2007;Luo, Feng, He, Wang, & Luo, 2010;Rellecke, Palazova, Sommer, & Schacht, 2011), others have not (Balconi & Lucchiari, 2005;Eimer & Holmes, 2002Eimer, Holmes, & McGlone, 2003;Holmes, Vuilleumier, & Eimer, 2003;Schupp et al, 2004).…”
