The verb vocabularies of late talkers

Verb knowledge constitutes an important piece of language acquisition, given the role that verbs play in the development of morphosyntax. Conversely, differences in verb vocabulary may exacerbate broader deficits in children with or at risk for language disorder. This talk explores the verb vocabularies of late talkers, who are defined by their atypically small expressive vocabularies and who are at increased risk for DLD. In a series of studies, I explore 1) whether there are differences in verb vocabulary composition between late talkers and typically developing children, and 2) whether late talkers use the same cues to acquire verb meaning as typically developing children. Results indicate that, as compared to age-matched peers, late talkers have subtle differences in their vocabulary composition, and they are not as successful at acquiring new verb vocabulary. Together, these studies provide new insights into late talkers’ knowledge of verbs, which may ultimately explain differences in long-term outcomes.
