“…The current study focusses on the literacy components of reading fluency and spelling, as prevalence studies report dissociations (Fayol, Zorman, & Lété, 2009;Moll & Landerl, 2009;Wimmer & Mayringer, 2002), resulting in subgroups with isolated reading deficits (RD), isolated spelling deficits (SD), and combined reading and spelling deficits (RSD) Moll, Kunze, Neuhoff, Bruder, & Schulte-Körne, 2014;Moll & Landerl, 2009;Torppa, Georgiou, Niemi, Lerkkanen, & Poikkeus, 2017;Wimmer & Mayringer, 2002). These subgroups are associated with different cognitive profiles.…”
