“…Moderate to severe delays have been reported in all aspects of language development including expressive and receptive vocabulary, syntax, and pragmatics (Fryns, Jacobs, Kleczkowska, & Van den Berghe, 1984;Newell, Sanborn, & Hagerman, 1983;Roberts et al, 2001;Sudhalter, Scarborough, & Cohen, 1991). In addition to language delays, speech intelligibility in conversation is often poor (Paul, Cohen, Breg, Watson, & Herman, 1984;Spinelli, Rocha, Giacheti, & Richieri-Costa, 1995). Pragmatic deficits may include perseverative speech and poor topic maintenance ( Belser & Sudhalter, 2001).…”
