Studies looking into second language development have shown that findings about a group of learners cannot be transferred to individual learners. In this study, we explored ways to meaningfully group individuals starting from the data and investigated whether this grouping can give extra information about learning trajectories that goes beyond the…

It has been largely argued that intrinsic motivation is the best and most effective in sustaining language learning. Deci and Flaste (1996) posit that motivation must come from within. While this might be possible and effective in contexts where learners have a personal interest in learning a language, it is not always the case for those learning…

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…

Engagement and willingness to communicate (WTC) are crucial elements for second language (L2) learning. However, little is written about whether L2 learners demonstrate heterogeneous patterns of engagement and WTC in the classroom. This study aims to identify intraindividual differences in these two constructs and examine the roles of eight…

We examined whether input modality and individual differences in attention and motivation influence second language (L2) learning via syntactic priming. In an online study, we compared the primed production of English passives by 235 L2 and native English speakers in reading-to-writing versus listening-to-writing conditions. We measured immediate…

The question of whether L2 learners can use discourse cues online during pronoun resolution remains debated in the field. We examine one factor that has been argued to impact pronoun resolution in native speakers, implicit causality (IC) bias, a property related to certain verbs in which one of verb's arguments are considered to be the cause of an…

In this paper, we report a longitudinal study of the effects of procedural task repetition on learners' task performance (i.e., syntactic complexity in relation to lexical complexity). We investigated how task repetition results in differences at the group and individual level across each task interval (T = 7). Intermediate-level Saudi learners of…

This study examines how listening comprehension difficulties (LCDs) vary among college-level learners of English as a Foreign Language (EFL), with a focus on the roles of gender and language proficiency. Listening comprehension is an essential component of language learning, presenting notable challenges for EFL students. These challenges are…

This study made triangulated use of eye-tracking and retrospective verbal reports (RVRs) to compare the banked gap-filling processes of two same-scorers and those of a top scorer and a bottom scorer. The two same-scorers differed in their cognitive effort on global and local processing, fluency of choice making, and strategy use when completing…

This study examines context effects on lexical processing by low-proficiency Japanese learners of English during sentence comprehension, and the role of individual differences in verbal working memory (WM). Thirty Japanese learners of English as a second language (L2) and 27 speakers of English as a first language (L1) were recruited for a…

Statistical learning (SL) approaches to reading maintain that proficient reading requires assimilation of rich statistical regularities in the writing system. Reading skills in developing first-language readers are predicted by individual differences in sensitivity to regularities in mappings from orthography to phonology (O-P) and semantics…

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…

The notion that digital games can be effectively employed as tools for learning and teaching has steadily been gaining traction among educational theorists and researchers, with numerous empirical studies pointing to the potential benefits of games for skill and knowledge development. However, a solid understanding of learners' attitudes and…

This article reports a qualitative case study on the translanguaging practices of Vietnamese English-as-a-foreign-language (EFL) educators and explores the mechanisms behind individual differences in their practices through an integrative cultural-historical activity theory perspective. Data were collected through semi-structured interviews,…

While evidence has accumulated to support the argument of shared computational mechanisms underlying language comprehension between humans and large language models (LLMs), few studies have examined this argument beyond native-speaker populations. This study examines whether and how alignment between LLMs and human brains captures the homogeneity…
