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…

There is a considerable amount of research investigating the impact of variables such as age, gender, and cognitive ability on second language acquisition. In second language acquisition, besides such individual variables, equal importance should be given to the social demographic variables. Therefore, it is crucial to direct this focus towards…

The aim of the present article is to provide a systematic review of qualitative studies in the leading journals of our field focusing on their distributional properties in the various journals as well as topic choice and selected quality control issues. In order to achieve this aim, we carried out a systematic review of research articles published…

The purpose of this article is to offer a narrative review of research on effective language learning environments for learners in the digital era. To do this, a search strategy was employed to retrieve both conceptual analyses and empirical studies, initially including whether published as journal articles or book chapters. The collected data…

This review paper explores the role of individual differences in second language vocabulary learning, focusing on three key factors: out-of-class exposure (e.g., viewing TV, playing video games and listening to songs), strategic vocabulary learning, and motivation. Individual differences significantly impact vocabulary learning, making it crucial…

Researchers have agreed that language anxiety is situation-specific; however, whether existing instruments measure stable or transient components of this anxiety remains controversial. Therefore, this study examined language anxiety's trait stability and state variability. The results from synthesizing 21 test-retest correlations based on existing…

This systematic review investigated how successful children/adolescents with poor literacy skills learn a foreign language compared with their peers with typical literacy skills. Moreover, we explored whether specific characteristics related to participants, foreign language instruction, and assessment moderated scores on foreign language tests in…

Over the past decade, the focus of investigation in individual differences (IDs) research has shifted from the utilization of large-scale questionnaire surveys toward the adoption of methodological diversity and development of new approaches to second-language (L2) communication (Dörnyei and Ryan [2015]. "The Psychology of the Language…

Event-related potentials (ERPs) have become widespread in second language acquisition (SLA) research and a growing body of literature has been produced in recent years. We surveyed 61 SLA papers that use ERPs to study L2 sentence processing in healthy late learners. Our main aim was to provide a critical summary of findings from the decade…

Individual differences (IDs) have long been considered one of the most important factors explaining variable rates and outcomes in second language acquisition (Dewaele, 2013). While traditional operationalizations of IDs have, explicitly or implicitly, assumed that IDs are static traits that are stable through time, more recent research inspired…

The English language is a catalyst for economic growth, modernization, and globalization. In this milieu, English language competency--defined as the practical ability to use English effectively in diverse contexts, encompassing linguistic, cognitive, and intercultural skills--is recognized as an essential skill (Amor et al., 2023). Research on…

The purpose of this state-of-the-art review is to provide a general overview of recent research on time distribution and second language (L2) learning with special implications for classroom settings. Several studies have been performed to examine how to best distribute the hours of L2 practice to maximize learning by comparing conditions that…

This study offers a bibliometric analysis of research trends in task-based language teaching (TBLT) from 1985 to 2020. The analysis covers research questions related to the publication trends, venues for publication, productive authors, highly cited articles and references and, more importantly, the most frequently explored TBLT-related topics and…

Interaction is an indispensable component in second language acquisition (SLA). This review surveys the instructed SLA research, both classroom and laboratory-based, that has been conducted primarily within the interactionist approach, beginning with the core constructs of interaction, namely input, negotiation for meaning, and output. The review…

The aim of this review is to synthesize empirical studies on undergraduate language learners' experience abroad during a time period of a year or less. To help provide a framework to this synthesis, we begin our review by tracing the recent evolution of empirical mixed-method research on the learner, identifying problems and characteristics that…
