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…

A word often expresses many different morphological functions. Which part of a word contributes to which part of the overall meaning is not always clear, which raises the question as to how such functions are learned. While linguistic studies tacitly assume the co-occurrence of cues and outcomes to suffice in learning these functions (Baer-Henney,…

Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

Does complexity make multilingualism special? Since there is no unequivocal notion of complexity on which researchers agree, several characteristics that have been considered crucial for complexity are brought to bear on multilingualism. While multilingualism is fairly complex in some senses, for instance, because it requires that many variables…

Given the importance of collocational knowledge for second language learning, how collocation learning can be facilitated is an important question. The present study examined the effects of three different practice schedules on collocation learning: node massed, collocation massed, and collocation spaced. In the node-massed schedule, three…

In Krashen's theory of second-language acquisition he claims that there is distinction between language acquisition and language learning, a distinction which other second-language acquisition researchers have called "perhaps the most important conceptualization" in the field and which has made possible the most productive models of SLA.…

Construction Grammar has been a prominent framework in linguistic research for nearly three decades, attracting scholars from various disciplines, including language acquisition, corpus linguistics, and psycholinguistics. While considerable progress has been made in understanding the first language (L1) construction learning of various languages,…

In the late 1970s and early 1980s, Stephen Krashen developed Monitor Theory--a group of hypotheses explaining second language acquisition with implications for language teaching. As the L2 scholarly community began considering what requirements theories should meet, Monitor Theory was widely criticized and dismissed, along with its teaching…

In the field of educational psychology, self-regulation is part of a well-established research paradigm that has been extensively applied to learning contexts. However, despite proposals highlighting its benefits, some researchers claim that its cross-pollination into applied linguistics has been slow. In their recent "Applied…

The current study draws on synthetic techniques and bibliometric analysis to explore the patterns of scientific collaboration in light of methodological orientations. We examined 3,992 applied linguistics (AL) articles published in 18 top-tier journals from 2009 to 2018 and analyzed their methodological orientations and scientific collaboration.…

Language is subject to a variety of pressures. Recent work has documented that many aspects of language structure have properties that appear to be shaped by biases for the efficient communication of semantic meaning. Other work has investigated the role of social pressures, whereby linguistic variants can acquire positive or negative evaluation…

Since its inception in 2005, YouTube has grown to become one of the most trafficked online platforms in the world. Accordingly, second language (L2) research interest on the topic has also increased, with studies investigating its use in formal and informal settings. Given this, the goal of this conceptual paper is to identify patterns within L2…

This article revisits the role of cognitive individual differences in creating synergies between second language (L2) writing and second language acquisition research that were proposed by Kormos (2012). It takes stock of the advances in research findings, in the past decade, on the role of working memory and language learning aptitude in L2…
