“…For example, the eyes contain information that allows us to better identify and recognize specific individuals (McKelvie, 1976). They also provide valuable information about the direction of a person's visual attention which has critical implications for understanding intentions, preferences, and approach-avoidance behaviors (Adams & Kleck, 2003Hietanen, Leppänen, Peltola, Linna-Aho, & Ruuhiala, 2008;Itier & Batty, 2009;Mason, Hood, & Macrae, 2004;Mason, Tatkow, & Macrae, 2005).The above research indicates that attending to the eyes can help us form impressions and regulate social interactions (Frischen, Bayliss, & Tipper, 2007;Kleinke, 1986;Nummenmaa, Hyönä, & Heitanen, 2009;Richmond, McCroskey, & Hickson, 2007;Wirth, Sacco, Hugenberg, & Williams, 2010). Recent work, however, has also demonstrated that individuals who do not preferentially attend to others' faces and eyes commonly experience social (Yardley, McDermott, Pisarski, Duchaine, & Nakayama, 2008) and developmental deficits (Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001;Baron-Cohen, Wheelwright, & Jolliffe, 1997).…”
