A model for L1 grammatical attrition

A model for L1 grammatical attrition
A model for L1 grammatical attrition
This article proposes a formal model of the human language faculty that accommodates the possibility of ‘attrition’ (modification or loss) of morphosyntactic properties in a first language. Modelling L1grammatical attrition entails a quite fundamental paradox: if the structure of the language faculty in principle allows for attrition of morphosyntax, why is it apparently so heavily constrained and rarely attested? We demonstrate that the attrition paradox can be resolved with a model that integrates a formally explicit generative grammar (eschewing classical parameters in favour of functional feature assemblies; see Chomsky 2000, 2001) into a generalised model of language acquisition that decouples linguistic input from acquisitional intake (following Lidz and Gagliardi 2015). This implementation makes specific predictions about the input and intake conditions that favour and disfavour L1 attrition. We explore these predictions for one of the most widely studied areas of attrition, namely the realisation of pronominals.

Abstract

This article proposes a formal model of the human language faculty that accommodates the possibility of ‘attrition’ (modification or loss) of morphosyntactic properties in a first language. Modelling L1grammatical attrition entails a quite fundamental paradox: if the structure of the language faculty in principle allows for attrition of morphosyntax, why is it apparently so heavily constrained and rarely attested? We demonstrate that the attrition paradox can be resolved with a model that integrates a formally explicit generative grammar (eschewing classical parameters in favour of functional feature assemblies; see Chomsky 2000, 2001) into a generalised model of language acquisition that decouples linguistic input from acquisitional intake (following Lidz and Gagliardi 2015). This implementation makes specific predictions about the input and intake conditions that favour and disfavour L1 attrition. We explore these predictions for one of the most widely studied areas of attrition, namely the realisation of pronominals.
