“…Working memory refers to the ability to temporarily maintain and manipulate information necessary for achieving a certain goal (Gropper, Gotlieb, Kronitz, & Tannock, 2014). The largest group of studies (n = 9) reported on working memory or related to time estimation, explanatory style, or written expression (Sparks, Javorsky, & Philips, 2004;Gropper et al, 2014;Gropper & Tannock, 2009;Lineweaver et al, 2012;Jones, Craver-Lemley, & Barrett, 2008;Prevatt, Proctor, Baker, Garrett, & Yelland, 2011;Prins, Dovis, Ponsioen, ten, & van der Oord, 2011;Semrud-Clikeman & Harder, 2011;Shmulsky & Gobbo, 2007). ADHD students display significant weaknesses in the auditory-verbal working memory tasks compared to controls and were significantly worse in time estimation abilities.…”
