“…Among normal participants, the mechanisms that underlie social attribution to geometric shapes affect higher social cognition such as mental state attribution and judging interactions as interpersonal (Castelli, Happé, Frith, & Frith, 2000; Gobbini, Koralek, Bryan, Montgomery, & Haxby, 2007; Schultz et al, 2003). These mechanisms help detect goal-directed motion, attribute intention, distinguish intentional movements from mechanical ones, and dissociate intentionality from animacy detection (Blakemore et al, 2003; Gao, Scholl, & McCarthy, 2012; Lee, Gao, & McCarthy, 2014; Stosic, Brass, Van Hoeck, Ma, & Van Overwalle, 2014). From these investigations, and others, two basic aspects of social attribution emerge: that of ascribing animacy (van Buren, Uddenberg, & Scholl, 2016; Gao and Scholl, 2011; Santos et al, 2010; Schultz & Bülthoff, 2013), and that of ascribing agency (Gobbini et al, 2007; Osaka, Ikeda, & Osaka, 2012; Stosic et al, 2014).…”
