This article offers the author's commentary on the Multiple Grammars (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue. Multiple Grammars advances the claim that optionality is a constitutive characteristic of any one grammar, with interlanguage grammars being perhaps the clearest examples of a…

Analysing the effects of second language (L2) production on L2 learners' interlanguage (IL) modifications is the main scope of this paper. For this purpose, English L2 learners' output production and IL modifications in performing two different task types, one-way and two-way tasks, are compared. The one-way task used in this study was a story…

Presents arguments for the view that pidginization can be a model of early second language acquisition, decreolization can be a model for later second language acquisition, and creolization is inappropriate for any aspect of this process. (Author/AM)

Examines Krashen's Monitor hypothesis (claiming that no interface exists between acquisition and learning) and finds it inadequate due to the over-restrictive conditions necessary for its use. Alternative acquisition theories and ways in which to monitor under less restrictive conditions are also examined, and a communicative trigger is proposed…

Firth and Wagner (1997) questioned the dichotomies nonnative versus native speaker, learner versus user, and interlanguage versus target language, which reflect a bias toward innateness, cognition, and form in language acquisition. Research on lingua franca English (LFE) not only affirms this questioning, but reveals what multilingual communities…

Responds to a previous article criticizing the variation models of second-language acquisition (SLA), and argues that the variation models can and do explain (SLA) and that any adequate model of SLA should take interlanguage into account. (Author/VWL)

A proposed model for an interim grammar between a first and second language, an autonomous rule-governed system based on the Extended Standard Theory, is presented and discussed, focusing on the motivations for choosing a generative model and the determination of structure for an interlanguage system, and using a comparison of the auxiliary system…

Examines five cognitive models for second-language acquisition (SLA) and assesses how each might account for the Pidginized interlanguage found in the early stages of second-language acquisition. (23 references) (JL)

Examines the work of two scholars who have made the greatest contributions to the variabilist perspective on second-language acquisition, and discusses the acquisition models that each of these scholars has proposed. (50 references) (Author/VWL)

Answers to theoretical questions about the place of input in a formal second language acquisition model are dependent on a distinction between two kinds of learner hypotheses. Type-N hypotheses require "negative evidence" for testing, while Type-P hypotheses are tested on the basis of "positive data" alone. (Author/CB)

Considers the interplay between source and target language in relation to two points made by Klein and Perdue: (1) the argument that the analysis of the target language should not be used as the model for analyzing interlanguage data; and (2) the theoretical claim that under the technical assumptions of minimalism, the Basic Variety is a "perfect"…

Evaluates arguments advanced in favor of special nativism in second-language acquisition (SLA). The article considers the following claims: Universal Grammar (UG) is the null hypothesis; any theory of SLA needs a theory of grammar; and showing that interlanguage grammars are underdetermined by the available input implies that UG must be accessible…

Outlines a contrastive analysis model and a non-contrastive analysis model for studying interlanguage in strictly bilingual settings, and suggests a bidimensional framework, including both linguistic and curricular components, for studying interlanguage in multilingual settings. (21 references) (CB)

Critiques Pienemann and Johnston (1987), an influential model of the acquisition of English as a second language (ESL) morphology. The article demonstrates that their proposals are incompatible with syntactic analyses of word formation and emphasizes that second language researchers must ensure that models of second language acquisition are…

Ellis's target article suggests that language processing is based on frequency and probabilistic knowledge and that language learning is implicit. These findings are consistent with those of SLA researchers working within a variationist framework (e.g., Tarone, 1985; Bayley & Preston, 1996). This paper provides a brief overview of this research…
