“…Further, individuals with DS have been reported to demonstrate increased use of stereotyped language as compared to TD controls of a similar mental age (Laws & Bishop, 2004), though at lower rates than observed in other developmental disabilities, such as FXS or ASD (Abbeduto, Brady, & Kover, 2007; Martin, G. E., Roberts, Helm-Estabrooks, Sideris, & Assal, 2012; Roberts et al, 2007). Of note, studies of pragmatic abilities in DS have historically only included boys or combined sexes without examining sex differences, despite well-documented sex differences in pragmatic abilities in typical development (Berghout, Salehi, & Leffler, 1987; Cook, Fritz, McCornack, & Visperas, 1985; Kothari, Skuse, Wakefield, & Micali, 2013; Leaper, 1991; Sigleman & Holtz, 2013). As such, and because DS is not caused by mutations in the sex chromosomes, findings in boys with DS have often been generalized to girls (Finestack, Palmer, & Abbeduto, 2012; Keller-Bell & Abbeduto, 2007).…”
