“…Once an emotional stimulus is presented, it changes the way subsequently presented neutral objects compete for attention. For example, the ability to detect a solitary neutral stimulus can be enhanced by presenting an emotionally arousing stimulus just beforehand (Bocanegra & Zeelenberg, 2009; Padmala & Pessoa, 2008; Zeelenberg & Bocanegra, 2010), at least if the stimulus has low spatial frequency (Lee, Baek, Lu, & Mather, in press). Moreover, the presentation of an emotional stimulus has also been shown to enhance the ability to identify a neutral target within an array of neutral distracters (Becker, 2009; Olatunji, Ciesielski, Armstrong, & Zald, 2011; Phelps, Ling, & Carrasco, 2006).…”
