“…Voluminous behavioral research shows that it is more complicated and effortful to represent negation than affirmation (Evans, Newstead, & Byrne, 1993;Gough, 1966;Hasson & Glucksberg, 2006;Kaup, 2001;MacDonald & Just, 2002;Slobin, 1966;Stupple & Waterhouse, 2009;Wason, 1965;Watson, 1961), and recent work in cognitive neuroscience has begun uncovering the neural signatures of this difference (Christensen, 2009;Kumar, Padakannaya, Mishra, & Khetrapal, 2013). Accordingly, one might expect knowledge ascriptions for positive claims to be higher in general, whether the source of belief is inference or perception, because "any variable that increases experienced ease of processing is also likely to increase judgments of truth" (Reber & Schwarz, 1999: 342).…”
