“…On the other hand, experimental probes have tended to identify persistent delays and/or deficits in both the perception and production of grammatical morphemes and syntax (Brown, 1984;Delage & Tuller, 2007;DesJardin, Ambrose, Martinez, & Eisenberg, 2009;Hammer & Coene, 2016;Koehlinger, Van Horne, & Moeller, 2013;McGuckian & Henry, 2007;Moeller et al, 2010;Norbury et al, 2001;Tomblin et al, 2015), including reductions in mean length of utterance (Koehlinger et al, 2013). For instance, such studies have shown that children and/or adolescents with MMHL show delays and/or deviancies in their production of English, French, and Dutch grammatical morphemes (Brown, 1984;Delage & Tuller, 2007;Hammer & Coene, 2016;McGuckian & Henry, 2007;Moeller et al, 2010;Norbury et al, 2001;Tomblin et al, 2015). Moreover, the limited numbers of studies that have examined syntactic development in children with mild to severe SNHL have tended to identify patterns of impaired performance even into adolescence (Delage & Tuller, 2007;Elfenbein, Hardin-Jones, & Davis, 1994;Moeller et al, 2010;Tuller & Delage, 2014;Tuller & Jakubowicz, 2004;cf.…”
