There is currently an explosion in the number and range of new devices coming onto the technology market that use digital sensor technology to track aspects of human behaviour. In this article, we present and exemplify a three-stage model for the application of digital sensor technology in applied linguistics that we have developed, namely,…

While Kachru's Three Circles model of World Englishes (Kachru 1985, 1986; Kachru and Nelson 1996) has been highly influential in highlighting the changing distribution and functions of English, it has also been criticized for its inability to account for the heterogeneity and dynamics of English-using communities, and for perpetuating the very…

Complexity, accuracy, and fluency have proved useful measures of second language performance. The present article will re-examine these measures themselves, arguing that fluency needs to be rethought if it is to be measured effectively, and that the three general measures need to be supplemented by measures of lexical use. Building upon this…

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)

Suggestions are presented for how the link between theoretical and applied phonology may be concretely defined for the purposes of research on second language phonological development. (71 references) (Author/VWL)

Responds to a previous article that attacks variabilists' accounts of second-language acquisition (SLA) by addressing the following issues: (1) the context dependency of theory in SLA research; (2) the competency performance distinction; (3) the problem of data in SLA research; and (4) explanations of SLA. (Author/VWL)

Discusses problems involved in scientific explanation in general and their relevance to theories of second-language acquisition (SLA) in particular. The property theory/transition theory distinction and the deductive-nomological model are examined. The use of Lipton's (1991) "best explanation" concept in evaluating SLA theoretical frameworks is…

Responds to claims regarding second-language acquisition (SLA) research. The claims refer to the existence of multiple theories in SLA research, relativism in the field and acceptability and testing of findings. The article argues that SLA is a process of exploration and speculation rather than one of discovery and proof and suggests that SLA is…

Argues that accuracy orders in morpheme acquisition by adult second language learners can be predicted by a model of morpheme classification, the 4-M model. The model identifies four types of morphemes; content morphemes, early system morphemes, and two types of late system morphemes. (Author/VWL)

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)

The main difference between the information-processing and Bialystok's Analysis/Control framework for first and second language learning is in their focus. The latter is equipped mainly to account for performance differences on metalinguistic tasks, while the former accounts for construction and reconstruction of implicit and explicit mental…

By presenting two theories of first and second language learning dichotomously, their fundamental similarity as information-processing theories is obscured and details of both positions are misrepresented. (Author/MSE)

Presents the Adaptive Resonance Theory (ART) model as a general framework for explaining common linguistic phenomena such as fossilization, categorical perception, vowel phonemicization, and linguistic rule formation. ART models are compared with cerebellar modes. (49 references) (GLR)

Outlines a psycholinguistic model of vocabulary acquisition in a second language in an instructional setting. The model is based on an understanding of the representational characteristics of the second language lexicon. (Author/VWL)

Describes attempts to formalize and characterize a theory of communicative competence, focusing on the advantages of a preference model (which identifies and grades learning variables in order of importance) and of models developed on the premise of parallel distributed processing (which suggest that such rule-based processing are in fact gross…
