Working memory (WM) is inherently dynamic and complex, being a multi-faceted system that links storage and processing components; yet it is widely understood as internal. Hence, in second language (L2) research, its connection to complex dynamic systems theory (CDST) remains underspecified. This paper seeks to bridge a gap between CDST and WM in L2 research. First, definitions of WM are reviewed, along with evidence for its relationship to L2 outcomes. Next, a brief overview of CDST highlights its metatheoretical and methodological implications. Three perspectives are presented to illustrate how WM can be viewed in terms of major tenets in CDST. These consider WM effects as: (1) context-dependent, (2) interrelated with those of other variables, and (3) amenable to change across the lifespan. Despite this reappraisal, numerous challenges remain. Thus, in addition to noting research opportunities, the paper also considers measurement issues, such as the determination of boundaries and selection of appropriate timescales. In closing, while WM studies have shown its influence on L2 proficiency and processing, to more fully understand its dynamic nature, what is needed is further research on the reciprocal influences of bilingual development and changes in WM components, such as control of attention.

Fundamental to complex dynamic systems theory is the assumption that the recursive behavior of complex systems results in the generation of physical forms and dynamic processes that are self-similar and scale-invariant. Such fractal-like structures and the organismic benefit that they engender has been widely noted in physiology, biology, and medicine, yet discussions of the fractal-like nature of language have remained at the level of metaphor in applied linguistics. Motivated by the lack of empirical evidence supporting this assumption, the present study examines the extent to which the use and development of complex syntax in a learner of English as a second language demonstrate the characteristics of self-similarity and scale invariance at nested timescales. Findings suggest that the use and development of syntactic complexity are governed by fractal scaling as the dynamic relationship among the subconstructs of syntax maintain their complexity and variability across multiple temporal scales. Overall, fractal analysis appears to be a fruitful analytic tool when attempting to discern the dynamic relationships among the multiple component parts of complex systems as they interact over time.

Not so long ago individual difference factors were perceived as relatively stable attributes of learners and it appeared that their impact on the outcomes of the language learning process could be determined in a straightforward manner. There was a widespread belief that it was sufficient to design appropriate data collection instruments, carefully validate them, collect the requisite data concerning the variable in question as well as learners’ attainment, and then apply the procedures of inferential statistics in order to arrive at conclusions in this respect (Dörnyei, 2005). Such findings could later be used as a point of reference for pedagogical implications for teachers. However, the findings of research conducted over the last decade, in particular such that has focused upon motivation and willingness to communicate (e.g., Dörnyei, MacIntyre and Henry, 2015), have clearly demonstrated that the situation is much more complicated, because such factors are subject to constant fluctuations, both over longer periods of time, sequences of classes, single lessons or even specific tasks implemented by teachers. This phenomenon brings with it a number of challenges, not only with respect to designing and conducting empirical studies but also in regard to the steps that should be taken to take account of learners’ individual profiles. The main aim of the present paper is to demonstrate how the dynamic nature of individual difference factors can be accommodated in empirical research as well as elucidating its consequences for the individualization of the process of language learning in the classroom and beyond.
