“…In summary, previous research suggests the following findings: first, behavior problems develop at different rates in children (Bongers et al, 2003;Bub et al, 2007;Fanti & Henrich, 2010;Grimm et al, 2009;Kolfler et al, 2011;Reynolds et al, 2010); second, sex moderates the development of behavior problems with males initially demonstrating higher eternalizing behaviors and females initially demonstrating higher internalizing behaviors (Bongers et al, 2003;Lahey et al, 2006); third, there are distinct subcomponents of STM (i.e., phonological storage and phonological rehearsal; Baddeley, 2003); and fourth, the subcomponents of STM are related to behavior problems (Bolden, Rapport, Raiker, Sarver, & Kofler, 2012;Hale et al, 2002). What is unknown, however, and what this study will uniquely examine, is whether phonological storage and rehearsal affect the development of behavior problems and whether sex moderates this effect.…”
