The computer-assisted language learning (CALL) field seems to change overnight with new technological affordances. Blake revisits his 2000 "LLT" article on computer-mediation communication (CMC) in order to reflect on how the field has examined this topic over the past decade or so. While the Interaction Hypothesis continues to guide…

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…

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…

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 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 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…

Lardiere (2003), in her reply to Lakshmanan and Selinker (2001), justifies the use of suppliance in obligatory contexts as a method of analysis in the investigation of the second language (L2) acquisition of past tense, and claims that such a method is characteristic of previous studies that have proposed the Aspect Hypothesis. It is argued here…

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)

Assesses the contributions made by different approaches to interlanguage pragmatics as a subfield of second language acquisition. Discusses how four particular perspectives on pragmatic development relate to each other. (Author/VWL)

Research assumptions and procedures of two studies of interlanguage (IL) phonology are examined and criticized. In both studies, syllable structure is used as a primary variable, but opposing claims are made about "open" and "closed" IL syllable structure preference. It is argues that: (1) neither IL study considers sufficiently the phonetic…

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)

Discusses the "null prep phenomenon" reported in studies of the second language (L2) development of extraction constructions. Reviews a proposal that null prep grammars represent a generalized procedure in L2 development, that of early reliance on A-bar binding construals when the target grammar requires wh-movement. Offers an…

The natural phonology theory, related to European structuralism, makes two fundamental assumptions: (1) phonemes are mental images of the sounds of language, and (2) phonological processes represent subconscious mental substitutions of one sound or class of sounds for another that are the natural response to the relative difficulties of sound…

Assumes unified language behavior including verbal, kinesic, and prosodic forms. Proposes that interlanguage theory should be expanded to include kinesic and prosodic modes of behavior. Suggests that acquisition of second-language kinesic and prosodic forms takes place similarly to acquisition of verbal forms and that acquisition is developmental,…

Sample accepted findings on learners, environments, and interlanguages are proposed along with some implications for second-language acquisition theories. (79 references) (JL)
