Native speakers show systematic variation in a range of linguistic domains as a function of a variety of sociolinguistic variables. This article addresses native language variation in the context of multicompetence, i.e. knowledge of two languages in one mind (Cook, 1991). Descriptions of motion were elicited from functionally monolingual and…

This article discusses the implications of "multicompetence" (Cook, 1991), defined as an individual's knowledge of more than one language, for language assessment. The growing psycholinguistic evidence highlighting variability in native speaker performance as a result of multicompetence is reviewed, evidence that further questions the validity of…

The way adults express manner and path components of a motion event varies across typologically different languages both in speech and cospeech gestures, showing that language specificity in event encoding influences gesture. The authors tracked when and how this multimodal cross-linguistic variation develops in children learning Turkish and…
