Caused motion events in Uyghur child language.

In view of recent typological work revealing important intra-typological variations among verb-framed languages in motion expression, we investigated children's acquisition of caused motion events in Uyghur. Four-, 6-, 8-, and 10-year-old children and adults participated in a cartoon narration task, and analyses of data in terms of syntactic packaging, semantic density, and information focus showed that, while children's use of packaging strategies involving complex syntax (i.e., subordination) - previously found to be challenging for children speaking verb-framed languages - was adult-like from age 8, they continued to diverge from the adult patterns for measures of semantic density and information focus at age 10. We take this developmental asymmetry as emanating from different kinds of knowledge entailed in encoding motion and suggest that they may be on different developmental timelines because they demand differential amount of experience with a language.
