“…Two approaches have been used, including surveys to obtain students' selfreported use of testing (Carrier, 2003;Gurung, 2005;Hartwig & Dunlosky, 2012;Karpicke, Butler, & Roediger, 2009;Kornell & Bjork, 2007;Kornell & Son, 2009;McCabe, 2011;Wissman et al, 2012) and laboratory observation studies that examine how students spontaneously use testing (Bottiroli, Dunlosky, Guerini, Cavallini, & Hertzog, 2010;Karpicke, 2009;Kornell & Bjork, 2008;Kornell & Son, 2009;Murphy, Sanders, Gabriesheski, & Schmitt, 1981;Murphy, Schmitt, Caruso, & Sanders, 1987;Son, 2005). The present study uses the latter approach, but evidence from both is relevant.…”
