This paper examines early syntactic development from a usage-based perspective, using transcripts of the spontaneous speech of two Englishspeaking children recorded at relatively dense intervals at ages 2;0 and 3;0. We focus primarily on the children’s question constructions, in an effort to determine (i) what kinds of units they initially extract from the input (their size and degree of specificity / abstractness); (ii) what operations they must perform in order to construct novel utterances using these units; and (iii) how the (...) units and the operations change between the ages of two and three. In contrast to nativist theories of language development which suggest that children are working with abstract syntactic categories from an early point in development, we suggest that the data are better accounted for by the proposal that children begin with lexically specific phrases and gradually build up a repertoire of increasingly abstract constructions.

Much recent work in Cognitive Linguistics and neighbouring disciplines has adopted a so-called usage-based perspective in which generalizations are based on the analysis of authentic usage data provided by computerized corpora. However, the analysis of such data does not always utilize methodological findings from other disciplines to avoid analytical pitfalls and, at the same time, generate robust results. A case in point is the strategy of using corpus frequencies. In this paper, we take up a recently much debated issue from (...) construction grammar concerning the association between verbs and argument-structure constructions, and investigate a construction, the English as-predicative, in order to test the predictive power of different kinds of frequency data against that of a recent, more refined corpus-based approach, the so-called collexeme analysis. To that end, the results of the application of these corpus-based approaches to an analysis of the as predicative are compared with the results of a sentence-completion experiment. Concerning the topic under consideration, collexeme analysis is not only shown to be superior on a variety of theoretical and methodological grounds, it also significantly outperforms frequency as a predictor of subjects’ production preferences. We conclude by pointing out some implications for usage-based approaches. (shrink)
