“…Methodologies commonly used in the addiction-related attentional bias literature include the visual/dot-probe task (e.g., Field et al, 2004; Lubman et al, 2000; Mogg et al, 2003), free viewing of naturalistic images (e.g., Rosse et al, 1993, 1997; Wong et al, 2006; Volkow et al, 2006) or the completion of a secondary task while viewing naturalistic images (e.g., Luijten et al, 2011, 2012; Nickolaou et al, 2013a), and the addiction-Stroop task in which drug-related words serve as task-irrelevant input (e.g., Carpenter et al, 2006; Cox et al, 2002; Marissen et al, 2006; see Cox et al, 2006, for a meta-analysis). Studies of value-driven attention in non-clinical samples, in contrast, tend to use simple visual stimuli in tasks designed to isolate spatial-attentional competition between the target and a distractor, such as the additional singleton and visual search paradigms (e.g., Anderson et al, 2011a, 2011b, 2014; Chelazzi et al, 2014; Feldmann-Wustefeld et al, 2016; Lee and Shomstein, 2014); however, the visual/dot-probe task (e.g., Failing and Theeuwes, 2014; Muller et al, 2016; Pool et al, 2014; Stankevich and Geng, 2014; Sun et al, in press), naturalistic images (Anderson, 2015; Hickey and Peelen, 2015), free viewing methods (Anderson and Yantis, 2012; Yamamoto et al, 2013), and the Stroop task (Krebs et al, 2010, 2011) have also been employed in the study of value-driven attention.…”
