“…For example, capture is most likely when the irrelevant stimulus is physically salient (Joseph & Optican, 1996;Pashler, 1988;Theeuwes, 1991), extremely surprising (Asplund, Todd, Snyder, Gilbert, & Marois, 2010;Horstmann, 2002), signals the presence of a new perceptual object , or if it enjoys some level of top-down prioritization (Folk, Remington, & Johnston, 1992;Wolfe, 1994). However, of greatest relevance to the current study, there is also evidence that capture depends on the availability of attentional resources, with it being most likely if some amount of resources remains untapped by one's central preoccupation (Du, Yang, Yin, Zhang, & Abrams, 2013;Santangelo & Spence, 2008). For example, capture can be eliminated if spare resources are occupied with a secondary task (Boot, Brockmole, & Simons, 2005;Santangelo, Olivetti Belardinelli, & Spence, 2007) or if attentional resources are fully "frozen" within the confines of an attentional blink (Du & Abrams, 2009).…”
