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 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…

Previous studies on second language (L2) acquisition of English dative alternation by Korean speakers (Oh and Zubizarreta, 2003, 2006a, 2006b) have shown that the acquisition of English benefactive double object (DO) (e.g. "John baked Mary a cake") lags behind that of its counterpart goal double object (e.g. "John sent Mary the letter"). This…

This study examines an interlanguage in which Moroccan learners of Dutch use non-thematic verbs in combination with thematic verbs that can be inflected as well. These non-thematic verbs are real dummy auxiliaries because they are deprived of semantic content and primarily have a syntactic function. Whereas in earlier second language (L2) research…

Discusses the scarcity of research on the characterization of the second-language (L2) initial state, where "L2 initial state" refers to the starting point of nonnative grammatical knowledge. The article emphasizes that exploring the mechanisms of "development" of interlanguage requires an understanding of what a particular stage changed "from."…

Argues that functional categories instantiated in the learners' first language (L1) transfer to the initial state of second language syntactic development. On the basis of Zulu interlanguage data on acquisition of the obligatory declarative complementizer "ukuthi" (that) by English native speakers, argues that Comp contains a null…

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…

Research on the role of the first language (L1) in second language (L2) learning is reviewed, offering historical background but focusing primarily on work within the last two decades. Attention is given mainly to two aspects of the L1-L2 relationship: positive transfer of knowledge from L1 in the process of learning L2, and negative transfer, or…

In this paper, the patterns of variability in the use of auxiliary verbs in English as a second language from speakers with a Persian ethnic background are compared to those of Persian, and English. The findings of the comparisons between L1, L2, and English help us determine how variable L2 is and what the sources of this variation are. Our…

Presents a detailed study of the second-language (L2) acquisition of English aspect by native speakers of Slavic languages. Results bring new evidence to bear on the theoretical choice between direct access to the L2 value or starting out the process of acquisition with the first-language value of a parameter, supporting the latter view.…

General theory of transfer of knowledge and skill in learning second languages and ways in which language awareness may contribute to second language learning are examined. It is concluded that while recent second language acquisition research work and theories do not support or refute transfer of general language principles to the learning of…

This article discusses how research on language transfer in the field of SLA can help to explain the origins of substrate influence in creoles and provide answers to more difficult questions concerning the distribution and verification of substrate features. First, it argues against the view that both SLA and transfer are not involved in the…

A study of the acquisition of Turkish and German by immigrant children in West Germany addressed three issues: (1) the role of cognitive development and age of learning in the process of language acquisition, (2) the role of transfer between languages, and (3) the effects of greater or lesser contact with native speakers of the two languages being…

A collection of studies of second language acquisition in Swedish, Dutch, Spanish, French, German, and English is presented using a cross-linguistic perspective. The following topics are covered: (1) cross-linguistic first language perspectives on second language acquisition research; (2) use of typological markedness conditions in Swedish as…
