This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Past work investigating spatial cognition suggests better mental rotation abilities for those who are fluent in a signed language. However, no prior work has assessed whether fluency is needed to achieve this performance benefit or what it may look like on the neurobiological level. We conducted an electroencephalography experiment and assessed…

Despite their importance, dynamic and diagnostic assessments (DigAs) have received little attention in phycological aspects of foreign language teaching and learning settings; therefore, this study compared the effects of dynamic and diagnostic assessment (DigA) on Afghan EFL learners' speaking fluency and accuracy (SFA), learning anxiety (LA),…

Unlike traditional methods, the communicative approaches draw on implicit and incidental ways of learning and contextualised exercises of grammar which improve language performance in terms of fluency and communicative competence. However, the discursive plan implies the use of high-level units of knowledge and the automatization of low-level…

Speech fluency has been extensively researched as a core construct for second language (L2) speaking assessment. Despite the broad consensus on its multifaceted nature, few researchers have empirically explored the dimensionality of this construct. Operationalizations of fluency vary across research and practice, using both holistic and…

This study investigates learner engagement in pedagogic task performance by triangulating multiple sources of data to gain insight into the cognitive and affective processes that take place on a range of tasks and how they engage learners of different target languages. The study provides a detailed analysis of 4 learners' second language (L2)…

We take a multidimensional perspective on the development of second language (L2) speaking ability and examine how changes in the underlying cognitive variables of linguistic knowledge and processing speed interact with complexity, fluency, and accuracy over the course of a 3-month Spanish study abroad session. Study abroad provides a unique…

Bilingual experience has an impact on an individual's linguistic processing and general cognitive abilities. The relation between these linguistic and non-linguistic domains, in turn, is mediated by individual linguistic proficiency and developmental changes that take place across the lifespan. This study evaluated this relationship by assessing…

This paper responds to "Exploring the dynamism between propositional complexity and error rate: a case study" (EJ1176705) by Jordan Van Horn (this issue). In her study, Jordan Van Horn analyzes asynchronous email exchanges between a native and nonnative speaker of English utilizing three methods of analysis: error analysis, complexity…

This study aimed at exploring the impact of mentor text modelling on Iranian English as a Foreign Language (EFL) learners' accuracy and fluency in writing tasks with different cognitive complexity in comparison with two conventional approaches to teaching writing; namely, process-based and product-based approaches. To this end, 60 Iranian EFL…

The present study explored the relation between language control and nonverbal cognitive control in different bilingual populations. We compared monolinguals, Dutch-French unbalanced bilinguals, balanced bilinguals, and interpreters on the Simon task (Simon & Rudell, 1967) and the Attention Network Test (ANT; Fan, McCandliss, Sommer, Raz,…

This study investigates the combined effects of task-based careful online planning and the storyline structure of a task on second language performance (complexity, accuracy and fluency). Sixty intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline…

The impetus of the present study was to scrutinize the impact of planning and proficiency on 172 EFL learners' written task performance regarding concept load, fluency, complexity and accuracy. Planning was operationalized at two levels: pretask planning (PTP) and online planning (OLP). Participants of this study were two groups, high and low…
