“…Rates of language impairment are reported to reach 24% to 65% in samples of children identified as exhibiting disruptive behaviors (Benasich, Curtiss, & Tallal, 1993) and 59% to 80% of preschool-and schoolage children identified as exhibiting disruptive behaviors also exhibit language delays (Beitchman, Nair, Clegg, Ferguson, & Patel, 1996;Brinton & Fujiki, 1993;Stevenson, Richman, & Graham, 1985).
