| summary | The study of development reveals that early linguistic productions by children are not mere structural copies of adult utterances: there are certain systematic discrepancies which call for an explanation. One important task of developmental linguistics is to precisely describe these discrepancies, and the changes they undergo. The analytic tools provided by formal syntax have turned out to be precious in this respect, but we want to go beyond an accurate descriptive chart of development, and try to understand what the inner causes are of the observed developmental course: why does the child entertain partially non-target consistent systems, producing structures that she does not hear? And what makes her eventually converge to the target system? In this talk I would like to argue for a grammar-based and performance-driven approach to the target inconsistencies in child language, developing a line of inquiry which I presented in work of the last few years (e.g., Rizzi 2005). The central idea is that the language acquisition device initially recruits certain parametric values which facilitate the task of the child’s immature performance systems. The strategy thus is grammar based, as it involves the use of genuine options of Universal Grammar, but performance driven, as it is determined by the immaturity of performance systems. The empirical phenomenon which I will mainly focus on to substantiate this approach is the familiar case of systematic subject drop observed in child language. The analysis will integrate the grammar-based, performance-driven perspective on development with two advances in theoretical and descriptive syntax: the cartography of syntactic structures (Belletti ed. 2004, Cinque 1999, Cinque ed. 2002, Rizzi ed. 2004a), and Phase Theory (Chomsky 2001, Nissenbaum 2000). |
