“…Previous studies had shown that perception of sample stimuli can affect the perception of a subsequent test stimulus, a phenomenon widely known as priming (Guillem, Bicu, & Debruille, 2001;Henson et al, 2003;Rugg, Mark, Gilchrist, & Roberts, 1997;Schweinberger, Pfütze, & Sommer, 1995;Trenner, Schweinberger, Jentzsch, & Sommer, 2004). It has also been shown that subjects' awareness of the task at hand can affect both sample-stimulus perception (Curran, Tanaka, & Weiskopf, 2002) and its priming effect on the following test stimulus (i.e., a differential priming effect; Schweinberger, Pickering, Jentzsch, Burton, & Kaufmann, 2002).…”
