The present study assesses linguistic and geographic diversity in selected outlets of SLA and multilingualism research. Specifically, we examine over 2,000 articles published in specialized top-tier journals, recording the languages under study and their acquisition order, author affiliations, the country in which the research was conducted, and…

A lot of attention has been devoted in the last 30 years to understanding nativeness and what has traditionally been called non-nativeness. While many studies have attempted to problematize the dichotomic division between so-called native speakers and non-native speakers, several others have specifically focussed on the language teaching…

This paper reports a bibliometric analysis of two small data sets: a set of 34 papers that make up "The Routledge handbook of vocabulary studies" (Webb, 2020) and a set of papers dealing with second language (L2) vocabulary research taken from a single journal "Frontiers in Psychology." Bibliometric maps based on author…

Identifying changing patterns of stability and variability is crucial when examining second language development (SLD) from a complex dynamic systems theory (CDST) perspective (Larsen-Freeman, 2020). By studying attractor states, or recurrent patterns of stability, light can be shed on the underlying dynamics of a complex dynamic system (van Geert…

Nowadays, research in second language acquisition (SLA) is becoming increasingly interdisciplinary while many technical frontiers and research hotspots have emerged. Many studies focus on interdisciplinary topics, but few in-depth studies have been conducted on interdisciplinarity. This study examined the interdisciplinarity of SLA and the…

Structural equation modeling (SEM), as a flexible and versatile multivariate statistical technique, has been growingly used since its introduction in the 1970s. This article presents a methodological synthesis of the characteristics of the use of SEM in L2 research by examining the reporting practices in light of the current SEM literature to…

Second language development can be viewed as a complex and dynamic process in which learners follow non-linear trajectories and develop their language over a period of time (Larsen-Freeman, 2006). Intrinsic to the view of Complex Dynamic Systems Theory (CDST), a system is composed of hierarchical, interdependent subcomponents (learner, learner…

From a complex dynamic systems (CDST) perspective, language is understood as a dynamic system comprised of subsystems that change and develop over time in response to learner-internal and -external factors (Verspoor et al., 2008). Accordingly, language development is seen as a process responsive to the dynamic interaction between the learner and…

Adopting Complex Dynamic Systems Theory (CDST) in Second Language Acquisition (SLA) is a testament to the revolutionary and evolutionary advancement in theory and empirical practice in the field. CDST is revolutionary for the fact that it warrants systems thinking of SLA phenomena that breaks the chain of dichotomous conceptualization on vital…

In current research into second language (L2) speaking, aspects of fluency are measured as static constructs. Averaged over a complete speaking performance, for instance, syllables per minute is calculated. Similarly, the number of pauses is calculated per minute, averaged over a complete speaking task. This paper argues, however, that we need to…

Language teachers report having limited direct contact with research and research findings despite generally positive perceptions of research (Borg 2009; Marsden and Kasprowicz 2017; Nassaji 2012). Key reasons teachers give are 1) practical - a lack of time and access, and 2) conceptual - academic papers can be difficult to read (Plavén-Sigray et…

This article examines the use of the repertory grid technique as a method to investigate learner perceptions in language education research. An important issue raised in this article concerns how far a researcher's agenda may be unintentionally imposed onto a research study which is investigating learners' perceptions, and how far the ensuing data…

This meta-analysis synthesized 35 English studies (130 effect sizes, N = 1,981) that employed online tasks to investigate the processing of multiword sequences (MWSs). We examined (a) to what extent MWSs enjoy a processing advantage over novel word combinations; (b) how such a processing advantage is moderated by statistical regularities (i.e.,…

Replication is a research methodology designed to verify, consolidate, and generalize knowledge and understanding within empirical fields of study. In second language studies, however, reviews share widespread concern about the infrequency of replication. A common but speculative explanation for this situation is that replication studies are not…

Migration, among the most important sociocultural phenomena of contemporary global societies, is complex, dynamic, and multifaceted. At the heart of migration is language, the indispensable agent of migration. Hence, in this article, a new sub-discipline of linguistics is presented, and that is 'migration linguistics'. It is the interdisciplinary…
