Saussure proposed the division language/parole and argued that language can be studied as a formal system. Fifty years later Chomsky declared competence the core interest of linguistics. Although for years Generative second language acquisition (GenSLA) has adopted this view, a number of recent publications poke holes into the competence bubble.…

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. Modeling L1 grammatical attrition entails a quite fundamental paradox: if the structure of the language faculty in principle allows for attrition of…

We study the learnability problem concerning the dative alternations in English (Baker, 1979; Pinker, 1989). We consider how first language learners productively apply the double-object and to-dative constructions ("give the book to library"/"give the library the book"), while excluding negative exceptions ("donate the…

Replies to Mellow's (1996) criticism of the authors' second language acquisition model. The article argues that this model is based on the psychological concept of exchange of linguistic information and that Mellow's evaluation of various types of transformational analysis is irrelevant. The article also addresses several points of detail in…

Discusses the structuralist and the cognitivist theories of language learning, and emphasizes the importance of practice in second language learning. (AM)

Challenges the idea that grammatical representations in second-language development are parametric values that are transferred from the learner's native language, offering learner data incompatible with this view. Advocates a weak transfer model in which lexical and functional projections transfer, but morphology-driven values of features like the…
