This book provides an overview and analysis of the role that classroom interaction plays in instructed second language acquisition. The authors synthesise current state-of-the-art research on how classroom interaction benefits L2 learning through the lens of three theoretical perspectives: cognitive-interactionist (with a focus on how…

It is often assumed that all languages are fundamentally the same. This assumption has been challenged by research in linguistic typology and language evolution, but questions of language learning and use have largely been left aside. Here we review recent work on Danish that provides new insights into these questions. Unlike closely related…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

Previous papers in these pages have dealt empirically with the child's first words, the child's first imitations, and the use of yes/no and wh-questions with infants. In this study, we touch on all these issues, but attempt to place them in a systemic-functional language framework and a cultural-historical learning one. First, we deal with some of…

Today, L.S. Vygotsky's concept of a 'zone of proximal development' (ZPD) is often used to just mean best practices in early years teaching, like scaffolding. But in his original theory, the zones linked age periods distinguished by age-specific neoformations -- one of which was the formation of concepts at adolescence. So Vygotsky rejected Stern's…

Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to "switch" between…

Acquisition in general and first language acquisition in particular is a very complex and a multifaceted phenomenon. The way that children acquire a language in a very limited period is astonishing. Various approaches have been proposed so far to account for this extraordinary phenomenon. These approaches are indeed based on various philosophical…

The double-deficit hypothesis (DDH) of developmental dyslexia was investigated in seven to twelve year old Spanish children. It was observed that the double deficit (DD) group had the greatest difficulty with reading.

A discussion of Stephen Krashen's Monitor Theory (1982) of second language acquisition examines five main hypotheses: the acquisition-learning distinction, the natural order hypothesis, the monitor hypothesis, the input hypothesis, and the affective filter hypothesis. Several problematic elements of the theory are pointed out. The discussion…

This study investigates whether the core bottleneck of literacy-impairment should be situated at the phonological level or at a more basic sensory level, as postulated by supporters of the auditory temporal processing theory. Phonological ability, speech perception and low-level auditory processing were assessed in a group of 5-year-old pre-school…

The utility of negative evidence as input for grammar construction in second language learning is examined. Three issues are dealt with in this paper: (1) the arguments for and against negative evidence in first and second language acquisition are paralleled; (2) the question is situated within the larger issues of learner end-products and the…

Three types of processes occur in language learning, each intricately connected with the others. Social processes are the steps by which learners and target language speakers create a social situation in which target language communication is possible and desired. Linguistic processes are the ways in which assumptions held by target language…

We discuss the results of an experiment that investigates English-French learners' interpretation of quantifiers with detachable restrictions. Such quantifiers are ungrammatical in English. We investigate aspects of interpretation that rely on a highly idiosyncratic interface between grammar and general principles of conversational cooperation in…

It is a good thing for the field of applied linguistics to adopt experimental methods of research where appropriate and to think more in terms of testable models of second language processing. However, there is a threat of psycholinguistics becoming the parent discipline, most likely temporary, of applied linguistics. This would be unwise for two…

Explores the requirements for a general theory of second language learning that accounts both for the fact that people can learn more than one language and for the generalizable individual differences that occur in such learning, and considers the formalization and testing of such a theoretical model.
