Previous research on second language (L2) vocabulary learning has examined the relationship between word properties and learnability (e.g. Ellis and Beaton 1993). Few studies, however, have examined patterns in partial word form learning as a method of assessing learnability and improving our understanding of allocation of processing resources…

This article critically scrutinizes a number of issues involved in the definition and operationalization of complexity, accuracy, and fluency (CAF) constructs. It argues for maintaining clearer distinctions between CAF, on the one hand, and notions such as linguistic development and communicative adequacy, on the other. Adequacy, in particular,…

John McHardy Sinclair has made major contributions to applied linguistics in three related areas: language in education, discourse analysis, and corpus-assisted lexicography. This article discusses the far-reaching implications for language description of this third area. The corpus-assisted search methodology provides empirical evidence for an…

Alderson's (2007) paper investigated whether subjective frequency counts for words might be a reliable substitute for corpus data. Alderson is critical of previous research which has found high correlations between corpus data and subjective estimates, and he argues that his own research, "has failed to show that frequency judgements can…

Currently, restrictive-language policies seem to threaten bilingual education throughout the USA. Anti-bilingual education initiatives have passed easily in California, Arizona, and Massachusetts, while one was closely defeated in Colorado, and federal education policy has re-invigorated the focus on English education for English language…

In this article, we examine current practices in the measurement of syntactic complexity to illustrate the need for more organic and sustainable practices in the measurement of complexity, accuracy, and fluency (CAF) in second language production. Through in-depth review of examples drawn from research on instructed second language acquisition, we…

This paper draws on complexity theory and post-modern sociolinguistics to explore how an ecological approach to language data can illuminate aspects of language use in multilingual environments. We first examine transcripts of exchanges taking place among multilingual individuals in multicultural settings. We briefly review what conversation and…

The effects of age on second language acquisition constitute one of the most frequently researched and debated topics in the field of Second Language Acquisition. Two different orientations may be distinguished in age-related research: one which aims to elucidate the existence and characteristics of maturational constraints on the human capacity…

The general aim of this article is to discuss the application of Usage-Based Linguistics (UBL) to an investigation of developmental issues in second language acquisition (SLA). Particularly, the aim is to discuss the relevance for SLA of the UBL suggestion that language learning is item-based, going from formulas via low-scope patterns to fully…

This research creates an empirically derived, pedagogically useful list of formulaic sequences for academic speech and writing, comparable with the Academic Word List (Coxhead 2000), called the Academic Formulas List (AFL). The AFL includes formulaic sequences identified as (i) frequent recurrent patterns in corpora of written and spoken language,…

The Cognition Hypothesis (Robinson 2005) claims that pedagogic tasks should be sequenced for learners in an order of increasing cognitive complexity, and that along resource-directing dimensions of task demands increasing effort at conceptualization promotes more complex and grammaticized second language (L2) speech production. This article…

This paper responds to calls for studies that investigate multiple types of word knowledge and the processes of word learning. Focusing on a single word, this three-month diary study describes the micro-development of an adult male's Japanese L2 lexical knowledge. In contrast to most L2 vocabulary acquisition studies, this study posits a dynamic…

The input enhancement hypothesis proposed by Sharwood Smith (1991, 1993) has stimulated considerable research over the last 15 years. This article reviews the research on textual enhancement of input (TE), an area where the majority of input enhancement studies have aggregated. Methodological idiosyncrasies are the norm of this body of research.…

Previous research has shown that during syntactic priming activities, L1 speakers produce more target structures when they are prompted by a lexical item that occurred in their interlocutor's previous utterance. This preliminary study investigated whether L2 speakers are similarly influenced by lexical items during syntactic priming activities.…

While language aptitude has been investigated actively within second language research, there is a current dearth of research on the effects of aptitude in cases of attrition. The aim of the present investigation was to explore the role of language aptitude for L1 proficiency in speakers who experienced a break with their L1 setting prior to…
