Research on second language (L2) acquisition in the generative tradition (GenSLA) addresses the nature of interlanguage competence, examining the roles of Universal Grammar, the mother tongue and the input in shaping the acquisition, representation and use of second languages. This field is sometimes dismissed by applied linguists as irrelevant…

Interlanguage has been the main development of field research on second language acquisition (SLA). According to Richard et al (1996) Interlanguage is one of the kinds of language that can be produced by second language learners in the process of acquiring or learning a new language. The influence of the universal grammar of the first language in…

This paper investigated the "be"-insertion phenomenon in L2 English. L2 learners often insert "be"-forms before thematic verbs, creating nontargetlike forms (e.g. "She is love ice cream"). Based on L2 data from learners of topic-prominent L1s, a group of researchers have claimed that such "be"-forms are…

Amaral and Roeper (this issue; henceforth A&R) argue that all speakers -- regardless of whether monolingual or bilingual -- have multiple grammars in their mental language representations. They further claim that this simple assumption can explain many things: optionality in second language (L2) language behaviour, multilingualism, language…

Optionality is a central phenomenon in second language acquisition (SLA), for which any adequate theory must account. Amaral and Roeper (this issue; henceforth A&R) offer an appealing approach to it, using Roeper's Multiple Grammars Theory, which was created with first language in mind but which extends very naturally to SLA. They include…

This article clarifies some ideas presented in this issue's keynote article (Amaral and Roeper, this issue) and discusses several issues raised by the contributors' comments on the nature of the Multiple Grammars (MG) theory. One of the key goals of the article is to unequivocally state that MG is not a parametric theory and that its…

This article offers the author's commentary on the Multiple Grammar (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue and touches on other second language acquisition research. Topics discussed include the concept of second language (L2) optionality, a hypothesis regarding the acquisition of the…

This paper presents an extension of the Multiple Grammars Theory (Roeper, 1999) to provide a formal mechanism that can serve as a generative-based alternative to current descriptive models of interlanguage. The theory extends historical work by Kroch and Taylor (1997), and has been taken into a computational direction by Yang (2003). The proposal…

This article examines the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roeper in the present issue and presents a critique of the research that went into the theory. Topics discussed include the allegation that the bilinguals and second language learners in the original article are primarily students in an academic setting, Amaral…

This dissertation investigates the acquisition of oblique relative clauses in L2 Spanish by English and Moroccan Arabic speakers in order to understand the role of previous linguistic knowledge and its interaction with Universal Grammar on the one hand, and the relationship between grammatical knowledge and its use in real-time, on the other hand.…

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…

Works on second language acquisition theories, affective variables and communicative competence, and interlanguage were compiled as a result of a symposium on universals of second language acquisition at the University of Wisconsin, Milwaukee. The papers include: "On the Variability of Interlangauge Systems" (Elaine Tarone); "Memory, Learning, and…

Theories and research on second language acquisition and grammatical theory are reviewed and discussed, especially those concerning the recent interest in understanding the nature of the language-learning faculty. The review includes work in the areas of universal grammar, interlanguage, parameterization of universal grammar, second language…

This article surveys the development of second language (L2) phonology over the last 40-50 years. Research in this area has grown from analyzing learners' errors in terms of Contrastive Analysis to proposals explaining L2 sound patterns in terms of constraints on interlanguage grammar. Although native language transfer has endured as one source of…

Theoretical assumptions and consequences of the Markedness Differential Hypothesis (MDH) are compared with the Contrastive Analysis Hypothesis, and empirical evidence favoring the former is reviewed. Pedagogical implications of the MDH, a strategy for interlanguage-intervention, and several problems revealed in the literature are discussed. (MSE)
