“…Research on dyslexia has primarily focused on the phonological processing deficits of this population, leaving other components of language largely unexplored, although a few studies have reported grammatical deficits. Our findings are more in line with recent reports of grammatical delay (Altmann, Puranik, Mikell, & Lombardino, 2005;Rispens, 2004) and morphological and morpho-syntactic deficits (Bar-Shalom, Crain, & Shankweiler, 1993;Casalis, Cole´, & Sopo, 2004;Joanisse et al, 2000;Mann, Shankweiler, & Smith, 1984;Rispens, 2004;Rispens, Roeleven, & Koster, 2004) in the oral language production of children and adults with dyslexia. Grammatical accuracy has been found to reliably distinguish clinical populations with language based learning disabilities from typically developing children (Fey et al, 2004;Mackie & Dockrell 2004;Windsor, Scott, & Street, 2000).…”
