Exemplar-learning and schematization in a usage-based account of syntactic acquisition

The early phases of syntactic acquisition are characterized by many input frequency and item effects, which argue against theories assuming innate access to classical syntactic categories. In formulating an alternative view, we consider both prototype and exemplar-learning models of categorization. We argue for a 'hybrid' usage-based view in which acquisition depends on exemplar learning and retention, out of which permanent abstract schemas gradually emerge and are immanent across the summed similarity of exemplar collections. These schemas are graded in strength depending on the number of exemplars and the degree to which semantic similarity is reinforced by phonological, lexical, and distributional similarity. © Walter de Gruyter 2006.
