“…Increasing evidence from humans indicates that contextual information – especially information about the body – influences how we understand facial behaviors (Hassin et al, 2013). The body also appears to communicate information about an individual’s emotion (de Gelder, 2006; de Gelder, de Borst, & Watson, 2015; Klin, Jones, Schultz, Volkmar, & Cohen, 2002; Kret & de Gelder, 2010; Kret, Stekelenburg, de Gelder, & Roelofs, 2015; Riby & Hancock, 2008; Smilek, Birmingham, Cameron, Bischof, & Kingstone, 2006; de Gelder, de Borst, & Watson, 2015; Kret, Stekelenburg, de Gelder, & Roelofs, 2015; for a reviews Hassin et al, 2013; Enea & Iancu, 2015; Hassin et al, 2013). Given the strong evolutionary claims made about homologies of emotion-related facial behaviors (Ekman, 1972; Keltner & Ekman, 2000; Shariff & Tracy, 2011) and the importance of bodies for communicating social information (Holland, Wolf, Looser, & Cuddy, 2016) in the absence of comparative data, evaluating how nonhuman primates process information about bodies during affective displays is critically important for establishing strong evolutionary theory.…”
