“…Overall, existing studies show substantial improvements in DM between kindergarten and early school years (e.g., Cavanaugh & Borkowski, 1980;Fritz, Howie, & Kleitman, 2010;Sodian, Schneider, & Perlmutter, 1986), with preschool children showing a basic understanding of metamemory-relevant variables (Kreutzer, Leonard, & Flavell, 1975;Lockl & Schneider, 2007;Wellman, 1977). Given the effects of metamemory on children's learning (Schneider, 2008), it is striking that very few studies have investigated the origins of children's knowledge about memory.…”
