“…The search pattern found for human targets in this study and in our previous study (Mayer et al, ) indicates a detection advantage within the human perceptual system for biological but not for mechanical objects. Elsewhere (Cavanagh, Labianca, & Thornton, ; Chandrasekaran, Turner, Bülthoff, & Thornton, ; Thornton, ; Thornton, Rensink, & Shiffrar, ) we have suggested that such an advantage could arise due to the availability of both bottom‐up (Bosbach, Prinz, & Kerzel, ; Mather, Radford, & West, ; Thornton & Vuong, ; Troje & Westhoff, ) and top‐down mechanisms (Bertenthal & Pinto, ; Bulthoff, Bulthoff, & Sinha, ; Thornton et al, ) specifically tuned for processing human form and motion.…”
