Opis:
Complex Dynamic Systems Theory (CDST) focuses on second language development (SLD) as opposed to second language acquisition (SLA). Emphasising internal complexity of the language system as well as dynamic and non-linear nature of language development, it represents a new approach to the role of variability which is rooted in developmental psychology. This approach agrees with research findings from the 1980s which identified different types and causes of variability, but it treats variability as the main factor responsible for language development and not as a peripheral phenomenon. Intra-individual variability, defined as differences in the level of a developmental variable within individuals and between repeated measurements, is said to have a positive influence on language development at various levels of proficiency. The present paper describes the third part of the case study whose aim is to analyse intra-individual variability in the emergence of lexical complexity in speaking English as a foreign language at secondary school in the case of a good, average and poor language learner. The first part of the case study examined this phenomenon with respect to general measures of complexity, accuracy and fluency, whereas the second part–with respect to specific measures of syntactic complexity. The results of the third part of the case study show some significant differences between the learners in terms of lexical variation as opposed to density, sophistication and frequency but hardly any such differences in intra-individual variability, pointing at the same time to a weak positive relationship between this type of variability and the rate of development.

Opis:
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.

Opis:
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.

Opis:
One of the main assumptions of Complex Dynamic Systems Theory (CDST) is that internally complex language subsystems develop non-linearly while entering different kinds of supportive, competitive, conditional, or dual relationships which are characterised by trade-offs caused by learners’ restricted cognitive processing, especially in foreign language speech. The present paper belongs to a short series of articles which examines various aspects of the development of L2 English speech at secondary school on basis of the same longitudinal, exploratory, and corpus-based case study. The aim of this paper is to investigate the dynamics of the relationships between fluency and both syntactic and lexical complexity in the speech of a good, average, and poor language learner at the level of secondary school. Syntactic complexity was investigated in terms of general sentence complexity, subordination, coordination, and nominalisation, whereas lexical complexity was construed in terms of lexical density, sophistication, and variation. In general, the results indicated predominantly supportive relationships between fluency and different measures of syntactic complexity but competitive or dual relationships between fluency and lexical complexity. However, the relationships between the selected variables fluctuated over time and often differed in the case of a good, average, and poor language learner.

Opis:
In line with Complex Dynamic Systems Theory (CDST), the aim of the paper is to examine dynamics and causality among the growth rates of lexical sophistication in L2 writing development. The study was based on The Written English Developmental Corpus of Polish Learners (WEDCPL) which consists of over 1,900 essays composed during 21 repeated measurements by 100 learners over three years (2014–2017) at secondary school. Lexical sophistication, operationalised as different frequency levels, was analysed with the Lextutor software (Cobb 2014). The results indicated that the learners relied on the first frequency level. The monthly growth rates (MGRs) of the frequency levels were variable but no significant peaks were registered. The relationships between the average semester growth rates (ASGRs) revealed competition between the first and higher frequency levels, and some support between the higher levels. Thus, developing learners’ lexis beyond the first level counteracts the production of lexically unsophisticated texts and supports the use of more advanced words.

Opis:
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.

Opis:
Complex Dynamic Systems Theory (CDST), which originated in the natural sciences, has recently been applied to second language acquisition, underlining the interdisciplinary character of this humanistic discipline. According to this theory, language is a complex dynamic system consisting of subsystems which develop in a non-linear way, forming different kinds of supportive, competitive, or conditional relationships. What is more, these subsystems compete for the learner’s limited resources, which causes trade-offs within and between language subsystems, such as complexity, accuracy, and fluency, especially in speech. The present paper constitutes a part of a short series of articles which present different aspects of the same longitudinal case study on the development of L2 English speech at secondary school. The aim of this paper is to examine the relationships between language accuracy and a number of specific measures of syntactic complexity, i.e. general sentence complexity, subordination, coordination, and nominalisation; as well as lexical complexity, i.e. lexical density, sophistication, and variation, in the case of a good, average, and poor language learner at secondary school. In general, the results showed that the relationships between the selected variables fluctuated over time and often differed in the case of a good, average, and poor language learner.

Opis:
Learners of foreign languages (L2s) apply strategies to support learning processes and L2 development. They select strategies according to their individual needs and preferences and adjust their strategic actions to suit situational circumstances and contextual conditions. A holistic investigation of strategic L2 learning processes requires the integration of numerous interconnected, flexibly-interacting influences, which are at constant interplay with each other and whose development is difficult to predict. Validated as effective in other fields of applied linguistics, complex dynamic systems theory (CDST) can also provide an appropriate frame for researching strategic L2 learning. Based on state-of-the-art methodological guidance for complexity research, this article presents the re-analysis of empirical data from a previous study through a complexity lens. It further examines the suitability of CDST in strategy research, explores its practical value, and demonstrates that a complexity perspective can generate new, profound information about strategic learning.
