“…Visual Search Efficiency is Greater for Human Faces Compared to Animal Faces Items in the environment that are of high biological significance appear to be located more efficiently than other items (e.g., Jackson, 2013; Öhman, 2007; Öhman, Flykt, & Esteves, 2001; Öhman, Soares, Juth, Lindström, & Esteves, 2012), though the proximate cause of this efficiency is debated (e.g., Horstmann & Bauland, 2006; Horstmann, Becker, Bergmann, & Burghaus, 2010; Horstmann, Lipp, & Becker, 2012; Yantis & Egeth, 1999). From an evolutionary perspective, according to the Animate Monitoring Hypothesis, human and nonhuman animals were the most important categories of visual stimuli for ancestral humans to monitor, as they presented challenges and opportunities for survival and reproduction, such as threats, mates, food, and predators (New, Cosmides, & Tooby, 2007; Orians & Heerwagen, 1992).…”
