Contrasting profiles of language development in children with williams and down syndromes
Abstract
We describe language acquisition in two distinct genetically based syndromes. Parents of children with Williams syndrome (WMS) and Down syndrome (DNS) were given the MacArthur Communicative Development Inventory (CDI), a parental report measure of child language development. Although both groups of children were found to be equally delayed according to normative standards, differential patterns of language acquisition emerged. Early in language development, the groups were differentiated primarily by a proclivity for gesture production by the children with DNS. Later in language development, the groups were cleaved by grammatical development: Children with WMS displayed a significant advantage over children with DNS. These findings are striking given the marked differences observed between adolescents and adults with WMS and DNS: Individuals with WMS exhibit linguistic skills superior to those of matched DNS controls despite significant but comparable cognitive deficits.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
