Second language (L2) motivation has long been regarded as one of the requisites for and predictors of success in L2 learning. The scholarship on L2 motivation has grown steadily over the past 60 years, yielding several theories through a range of methods. Building upon this tradition, this paper proposes a methodological contribution to the…

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…

Peter MacIntyre's 35-years of research in SLA, psychology of language learning, and communication was systematically reviewed in six sections driven by subjective guidelines developed for the purposes of the present survey. To operationalize the objectives of the sections, an impressionistic methodology was created for analysis, according to which…

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…

Goals are central to understanding how students learn a second language. Much of the existing research on goals in the field of language learning has focused exclusively on achievement goals, particularly mastery and performance goals. However, exclusively focusing on achievement goals precludes language researchers from exploring other important…

In this research note I want to address some misunderstandings about the construct of redeployment and suggest that we need to fit these behavioural data from Yang, Chen and Xiao (YCX) into a broader context. I will suggest that these authors' work is not just about the failure of three models to predict equivalence classification. Equivalence…

"Variability" and "fractality," two key concepts in Complex Dynamic Systems Theory (CDST)--the former concerning changes and variations, and the latter concerning recursiveness and self-similarities--may seem contradictory at first glance. This forum piece attempts to elucidate how the two seemingly contradictory properties can…

Purpose: Drawing on diverse findings in Second Language Acquisition (SLA) and Language Teaching research, but centering on the unique needs and contexts of international students in post-secondary education, this paper aims to develop a working theory of international students' continued language development. Design/methodology/approach: As a…

Second language acquisition (SLA) is a complex, interdisciplinary field of study which has its roots in subjects as varied as cognition and psychology to social applications and actions in anthropology and sociology (Han & Nassaji, 2019). Nearly a century ago, Soviet psychologist Lev Vygotsky attempted to connect the seemingly disparate areas…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

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…

The purpose of this state-of-the-art review is to provide a general overview of recent research on time distribution and second language (L2) learning with special implications for classroom settings. Several studies have been performed to examine how to best distribute the hours of L2 practice to maximize learning by comparing conditions that…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

Considerable reason exists to view the mind, and language within it, as modular, and this view has an important place in research and theory in second language acquisition (SLA) and beyond. But it has had very little impact on the study of working memory and its role in SLA. This article considers the need for modular study of working memory,…

In language conferences, student papers, some linguistics textbooks, and wider culture, the critical period hypothesis is presented as factual despite still being fiercely debated in academic literature. The widespread popular acceptance of the hypothesis contrasts with a sharp debate and criticism of it in academic literature (Muñoz &…
