“…In children and adults with FXS, social communication (i.e., pragmatics) is impaired, and these impairments are greater for individuals with comorbid ASD (Klusek, Martin, & Losh, 2014; Martin, Losh, Estigarribia, Sideris, & Roberts, 2013). However, the early social communication profile of infants and young children with FXS is largely unknown with few studies examining social communication at this age period (Flenthrope & Brady, 2010; Marschik et al, 2014; Roberts, Mirrett, Anderson, Burchinal, & Neebe, 2002). Marschik and colleagues (2014) investigated children with FXS 12 months and younger and found that most communication consisted of prelinguistic vocalizations with restricted gesture use.…”
