Integrating Cognitive Linguistics

and language evolution research Abstract. In this paper we argue that we can gain important insights on the evolution of language and cognition by integrating evolutionary linguistics and the framework of Cognitive Linguistics. In Cognitive Linguistics, language is seen as tightly integrated with cognition as a whole. Construction Grammar and usage-based approaches are closely related to the Cognitive-Linguistic paradigm. Construction Grammar proposes that knowledge of language can be defined as the knowledge of form-meaning pairings of different degrees of schematicity and complexity, whereas usage-based approaches stress that language acquisition and processing are based on instances of actual language usage. As we demonstrate in this paper, concepts from Cognitive Linguistics, Construction Grammar, and usage-based approaches can help in elucidating the cognitive and interactional factors involved in language evolution. The paper will focus on two main areas: In evolutionary linguistics, language is seen as a complex adaptive system whose structure emerges out of the interaction of three other complex adaptive systems at three different timescales: ontogeny, glossogeny, and phylogeny. Cognitive Linguistics can help in specifying common cognitive factors and processes that play a role on all three of these timescales. Secondly, a Cognitive-Linguistic and constructionist, usage-based perspective can shed light on the cognitive factors underlying the origin of the division of labour between contentful (“lexical”) and procedural (“grammatical”) constructions in language structure. In a Cognitive-Linguistic perspective, this development can be related to the trade-off between the cognitive factors of learnability and expressivity
