“…Regarding item-level suppression, three experiments measured age variability in FTT's recollection-rejection operation. Brainerd et al (2004) and Bouwmeester and Verkoeijen (2010) reported that it did not increase between early childhood and early adolescence, while Brainerd et al (2004) and Odegard et al (2008) reported substantial increases between early adolescence and young adulthood. Regarding disqualifying monitoring, the pre-study warning manipulation of Gallo, Roberts, and Seamon (1997) and the directed forgetting manipulation of Kimball and Bjork (2002) have been investigated (Carneiro & Fernandez, 2009;Howe, 2005), but there seems to be only one developmental study of the most-researched suppression operation of this type in adults, Schacter and associates' (e.g., Schacter et al, 1999) distinctiveness heuristic, and the procedures of that study (Ghetti et al, 2002) differed in certain respects from those of Schacter et al .…”
