“…Proponents of telegraphic speech argue that it is beneficial because it simplifies language processing, facilitates verbal imitation, and focuses children's attention on the relationship between semantic elements (e.g., agent-action; van Kleeck et al, 2010;Wolfe & Heilmann, 2010). Others argue that telegraphic speech is detrimental because morphosyntactic features of language provide useful information about the structure of language and the meaning of words, and omitting these features may put children at a disadvantage (Bedore & Leonard, 1995;Bredin-Oja & Fey, 2014;Fey, 2008;Fey, Long, & Finestack, 2003;van Kleeck et al, 2010). Our study informs this debate by investigating telegraphic speech use by parents of preschoolers with ASD and the association with their children's spoken language development.…”
