Studies in second language acquisition (SLA) increasingly rely on measures of linguistic complexity to assess second language (L2) proficiency and development. While an important number of studies have risen to the call of studying a broader range of complexity related constructs (Bulté and Housen, 2012; Norris and Ortega, 2009), few have examined…

Second language (L2) phonological acquisition involves learning novel target-language sounds, variable forms of sounds that arise in different phonological contexts, and any phonotactic constraints that govern their appearance. Interlanguage (IL) grammars must adapt to represent sounds and constraints that are novel to the native language (L1)…

This article explores the role of transfer and Universal Grammar (UG) in second language (L2) phonology by investigating the L2 acquisition of stress/prominence in footless languages, such as Turkish and French, which have fixed word- and phrase-final prominence respectively. It is proposed that once the prosodic constituent Foot is projected in a…

The decolonization of knowledge is increasingly high on the agenda of applied and sociolinguistics. This article contributes to this agenda by examining how peripheral multilingual scholars confront their linguistic and epistemic exclusion from global knowledge production. Based on the product of such a challenge -- a Chinese-centric special issue…

This commentary offers a brief reflection on the state of CALL in 1997, when "Language Learning & Technology" was launched with my paper entitled "CALL in the year 2000: Still in search of research paradigms?" The point of my 1997 paper was to suggest the potential value of research on second language learning for the study…

There remains considerable disagreement about which factors drive second language (L2) ultimate attainment. Age of onset (AO) appears to be a robust factor, lending support to theories of maturational constraints on L2 acquisition. The present study is an investigation of factors that influence grammatical and lexical complexity at the stage of L2…

There has been a great deal of research on first language (L1) and second language (L2) learning through meaning-focused input since Nagy, Herman & Anderson's (1985) seminal study of incidental vocabulary learning through reading. Two strands of research within this area are incidental vocabulary learning through listening and guessing from…

We present a framework of second and additional language (L2/L"n") acquisition motivated by recent work on socio-indexical knowledge in first language (L1) processing. The distribution of linguistic categories covaries with socio-indexical variables (e.g., talker identity, gender, dialects). We summarize evidence that implicit…

A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…

Tracey Derwing and Ron Thomson reflect on the growth of Canadian L2 pronunciation research from the early 1990s onward. Although many phoneticians and language educators called for pronunciation instruction (PI) for decades, in the early 1980s little empirical research existed to inform pronunciation pedagogy, despite an influx of Vietnamese…

Instructed second-language acquisition (ISLA) research endeavours to make positive changes in pedagogical practices. In this regard, there is a recent debate concerning whether teachers are (or should be) willing to engage with research. To investigate the research-pedagogy link, the current case study conducted interviews with 12 EFL teachers in…

This article reviews a selected sample of 70 empirical studies in journal articles and doctoral dissertations on language assessment in China between 2011 and 2018. Following a brief introduction to the history and current state of language assessment in China, the article presents a critical review of language assessment research on six themes…

Taking 1925, the founding year of "Language", the journal of the Linguistics Society of America, as a benchmark for "the past", and 2015 as benchmark for "the present", the author considers what was known then and what is known now about second language acquisition in applied linguistics. The field has grown more…

Traditions of statistical significance testing in second language (L2) quantitative research are strongly entrenched in how researchers design studies, select analyses, and interpret results. However, statistical significance tests using "p" values are commonly misinterpreted by researchers, reviewers, readers, and others, leading to…

Although classical statistical techniques have been a valuable tool in second language (L2) research, L2 research questions have started to grow beyond those techniques' capabilities, and indeed are often limited by them. Questions about how complex constructs relate to each other or to constituent subskills, about longitudinal development in…
