“…Prior work concerning difficulty-based self-regulated study indicates that the format in which to-be-remembered information is presented—namely, whether all at once (i.e., simultaneously) or single to-be-remembered units at a time (i.e., sequentially)—can notably impact later memory and the efficiency of study behaviors. Generally speaking, learners tend to prioritize difficult items over easier ones, allocating more time during study to the difficult subset and electing to restudy them more often than easier items (Dunlosky & Connor, 1997; Le Ny, Denhiere, & Taillanter, 1972; Mazzoni, Cornoldi, & Marchitelli, 1990; Nelson & Leonesio, 1988; Thiede & Dunlosky, 1999). There are, however, circumstances in which learners will appropriately shift their prioritization to easier items, such as when assigned a low performance goal (Thiede & Dunlosky, 1999) or under conditions of limited study time (Dunlosky & Thiede, 2004; Metcalfe, 2002; Son & Metcalfe, 2000; Thiede & Dunlosky, 1999).…”
