This study examined dual language learners' (DLLs n = 24) and English-only (EO n = 20) children's expressive and receptive language in kindergarten (M[subscript age] = 5.7 years) as well as the relation to peers' language use. Expressive language skills (vocabulary diversity, syntactic complexity) were measured in the fall, winter, and spring…

Ribot, Krystal M.; Hoff, Erika; Burridge, Andrea – Child Development, 2018
The unique relation of language use (i.e., output) to language growth was investigated for forty-seven 30-month-old Spanish-English bilingual children (27 girls, 20 boys) whose choices of which language to speak resulted in their levels of English output differing from their levels of English input. English expressive vocabularies and receptive…

Edgin, Jamie O.; Tooley, Ursula; Demara, Bianca; Nyhuis, Casandra; Anand, Payal; Spanò, Goffredina – Child Development, 2015
Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent-reported and objective measures of language, including…

Bohlmann, Natalie L.; Maier, Michelle F.; Palacios, Natalia – Child Development, 2015
Significant differences in language and self-regulation skills exist among children when they enter formal schooling. Contributing to these language differences is a growing population of dual language learners (DLLs) in the United States. Given evidence linking self-regulatory processes and language development, this study explored bidirectional…
