“…Of the few existing studies, some show that children with DS can acquire signs with relative ease (e.g., Miller, 1992; Woll & Grove, 1996), turning them later into spoken words (Kouri, 1989); while a few others suggest a positive impact of sign training on subsequent language development of children with DS (Launonen, 1996). The relatively few studies examining the effects of sign training in children with DS, with the added variability in the data collection procedures—from case studies (e.g., Kouri, 1989) to interventions with small samples (e.g., Launonen, 1996)— make it difficult to draw broader conclusions about the potential effects of baby signs on spoken vocabulary development in children with DS.…”

Baby sign but not spontaneous gesture predicts later vocabulary in children with Down Syndrome

Early spontaneous gesture, specifically deictic gesture, predicts subsequent vocabulary development in typically developing (TD) children. Here we ask whether deictic gesture plays a similar role in predicting later vocabulary size in children with DS, who have been shown to have difficulties in speech production, but strengths in spontaneous gesture and baby sign use. We compared the gestures and baby signs produced by 23 children with DS (Mage=2;6) and 23 TD children (Mage=1;6), in relation to their expressive spoken vocabulary size one year later. Children with DS showed significant deficits in gesture production, particularly for deictic gestures, but strengths in baby sign production, compared to their typically developing peers. More importantly, it was the baby signs produced by children with DS, but not deictic gestures, that predicted their spoken vocabulary size one year later. Our results further highlight the important role baby signs can play in language development in children with developmental disorders.

“…In a series of case studies referred to our sign language assessment clinic, we have begun to document sub-types of sign language developmental impairments (e.g. Woll & Grove, 1996;Atkinson et al, 2002). In this paper, we describe assessment of a deaf child exposed to adult models of BSL from birth with normal general cognitive abilities but very restricted BSL grammar.…”

“…Two case studies have been conducted addressing the effects of second language learning on the broader cognitive profile of DS. Woll & Grove (1996) examined visual memory in twins with DS bilingual in British Sign Language, and Vallar & Papagno (1993) showed enhanced working memory in a bilingual individual with DS. To our knowledge, no other studies have examined the effect of second language exposure (SLE) on neuropsychological function in this population or in any other ID.…”
