“…For example, in visual search tasks, pictures of snakes elicited faster response times than pictures of flowers in both humans (Öhman, Flykt, & Esteves, 2001) and macaque monkeys (Shibasaki & Kawai, 2009). In addition, faces with an angry expression are detected faster in a visual search task than happy or neutral faces (e.g., Öhman, Lundqvist, & Esteves, 2001;Pinkham, Griffin, Baron, Sasson & Gur, 2010; for a review, see Frischen, Eastwood & Smilek, 2008; but see Becker, Anderson, Mortensen, Neufeld, & Neel, 2011) and search times for emotional faces are not affected by array size (e.g., Eastwood, Smilek & Merikle, 2001;Fox et al, 2000;Juth, Lundqvist, Karlsson, & Öhman, 2005). The faster detection of emotional faces is probably most influenced by the heightened arousal induced by these faces (Lundqvist, Bruce, & Öhman, 2015).…”
