“…Behavioral researchers have pointed out that faces are unique among visual objects because they are socially relevant and contain multifaceted information, including cues pertaining to emotional content or one's identity [Bruce and Young, 1986;Ekman and Friesen, 1975]. Behavioral studies empirically confirmed that faces are perceived more rapidly [Hershler and Hochstein, 2005;Landau and Bentin, 2008;Purcell and Stewart, 1986;Ro et al, 2001;Tottenham et al, 2006] and memorized more accurately [Sato and Yoshikawa, 2013;Yin, 1969Yin, , 1970] than other objects. The studies also showed that multifaceted information in faces is processed in an integrative manner that supports such efficient/ robust face processing [Calder et al, 2000;McKelvie, 1995;Milders et al, 2006;€ Ohman et al, 2001;Sato and Yoshikawa, 2010].…”
