“…For example, manipulations of feedback (e.g., Estes & Maddox, 1995;Verde & Rotello, 2007), responsekey mappings (e.g., Rhodes & Jacoby;Starns & Olchowski, 2015), and some implicit or explicit information at test that a subject can use to judge a test item's potential probability (e.g., Heit, Brockdorff, & Lamberts, 2003;Selmeczy & Dobbins, 2013), or expected strength (Hicks & Starns, 2014), are often necessary. Additionally, participants' natural awareness of base rates (Titus, 1973;Rhodes & Jacoby, 2007) or of expected strength information (Starns & Olchowski 2015) seems to influence shifting. In our own laboratory we found that manipulating the base rates of targets versus lures does not motivate a criterion shift without explicit cues that accompany test items as being either likely old or likely new (see , for an analogous finding).…”
