This study examined the relationship between complexity, accuracy and fluency (CAF), using longitudinal data. Conducted from the perspective of complex dynamic systems theory (CDST), this research adopted four CAF general measures to track the development of five Chinese undergraduates' English speech over a 15-week period. LOWESS graphs supported…

This study is the first attempt to explore the relationship between rater variables focusing on raters' language aptitude and their judgments of second language (L2) speech. Thirty-four English listeners rated 65 spontaneous native and nonnative speech samples for comprehensibility, accentedness, and fluency. They also completed the LLAMA language…

This study examined individual-level variability in N400 and P600 ERP correlates of native and nonnative language sentence processing of semantic and grammar information. Twenty-six native English-speaking learners of Spanish as a second language were tested. Participants completed sentence reading tasks in English and Spanish during EEG…

Informed by Segalowitz's (Cognitive bases of second language fluency, Routledge, 2010) L2 speech production model and MacIntyre et al.'s (Mod Lang J 82(4):545-562, 1998. https://doi-org.bibliotheek.ehb.be/10.1111/j.1540-4781.1998.tb05543.x) L2 willingness to communicate model, this study sought to understand the influence of cognitive, affective and sociocultural…

An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

The purpose of this study was to examine the extent to which children's executive function predicted their reading comprehension performance. Participants were approximately 18,000 kindergartners in the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. The results suggest that individual differences in reading comprehension were…

Although a number of studies have been conducted to explore how various individual difference (ID) factors such as aptitude, motivation, and anxiety contributing to L2 learners' speech performance over a period of time of L2 learning, only a few examined the effect of the three ID factors on learners' L2 speech performances based on classroom…

The present study investigates the effect of task repetition and individual differences on Vietnamese English as a foreign language (EFL) learners' lexical use and fluency in oral task performance. The study adopts a within-subjects design with forty students performing the same narrative task twice. Students also completed two prior vocabulary…

The role of individual differences in second language (L2) learning is widely acknowledged; however, how teachers can accommodate individual differences in L2 classrooms receives relatively less attention. Focusing specifically on motivation, this study explores the effectiveness of communicative tasks on Korean L2 speakers' complexity, accuracy,…

From the perspective of complexity theory and based on Robinson's Cognition Hypothesis and the Triadic Componential Framework, this paper investigated the effect of manipulating task complexity along resource-dispersing dimension on L2 written performance. The results showed that: 1) Significant interactive effects were found between the two…

Studies that have measured pragmatic fluency in the form of planning time and speech rate, as indicators of processing ability, have confirmed that learners' processing ability and pragmatic knowledge are independent from each other. The present study is a longitudinal, developmental investigation which investigates whether the study abroad stay…

Widely implemented in Europe over the last three decades, Content and Language Integrated Learning (CLIL) has been researched in some European contexts more extensively than in others, with the Norwegian context being among the least represented. This paper attempts to contribute to filling in the gap by examining the impact of a short-term CLIL…

It is unknown whether and to what extent cognitive individual differences may play different roles in paper versus computer-based second language (L2) writing. This exploratory study is a first attempt to explore this issue, focusing on the effects of working memory and language aptitude on the quality of paper versus computer-based L2 writing…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…
