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…

Causal inference is a fundamental goal of many research endeavors, including scholarship in the field of language education and learning. Randomized controlled trials are considered an ideal design to test causal claims, but not all claims can be subjected to experimental treatment due to ethical and practical constraints. In this article, we…

This study used idiodynamic methodology to investigate the dynamics of second language (L2) learners' foreign language anxiety (FLA) and foreign language enjoyment (FLE), and the details of emotion regulation (ER) directed at managing these emotions, in pair- and group-work speaking tasks performed by 10 advanced English-as-a-foreign-language…

This study addresses the role of awareness in learning and the variables that may facilitate adult second language (L2) implicit learning. We replicated Williams's (2005) study with a similar group of academic learners enrolled at university as well as a group of non-college-educated adults in order to explore the generalizability of the findings…

Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

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…

An important issue in second-language acquisition concerns the role of explicit information (EI) and how it is affected by individual differences. The present study explored this question through a partial replication and extension of Fernández (2008: Experiment 2), which investigated the effects of EI in processing instruction (PI) for the…

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…

A growing body of evidence demonstrates that individual differences in declarative memory may be an important predictor of second language (L2) abilities. However, the evidence comes from studies using different declarative memory tasks that vary in their reliance on verbal abilities and task demands, which preclude estimating the size of the…

Research on the factors influencing the acceptance of GenAI in language learning has expanded widely; however, few studies have focused on the role of language learning emotions. To enhance the effectiveness of GenAI-powered English-speaking instruction and the learning experience, this study expands on the Integrated Model of Technology…
