Second language (L2) learners' beliefs about the nature of language learning, specifically language mindsets, is a recent productive line of L2 research. Researchers argue that language mindsets are key factors for language learning success. However, the association between language mindsets and different language learning outcomes is inconsistent…

Despite numerous studies involving personality traits and second language (L2) learning achievement over many years, there is a lack of an overall picture about how personality traits are related to L2 learning achievement. This study aims to conduct a systematic quantitative synthesis of the studies that examined the relationships between the Big…

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…

Background: Behavioural intention (BI) has been predicted using other variables by adopting the technology acceptance model (TAM). However, few studies have examined whether BI can predict learning performance. Objectives: The present study used an extended TAM to investigate whether students' BI is a predictor of their listening learning…

This study focuses on the predictive power of linguistic (i.e., general English proficiency; identified simply as "proficiency" in this paper) and non-linguistic (i.e., language learning anxiety and self-regulation) factors on the academic success of English medium instruction (EMI) students studying in engineering and social sciences…

The present meta-analysis aimed to improve on Involvement Load Hypothesis (ILH) by incorporating it into a broader framework that predicts incidental vocabulary learning. Studies testing the ILH were systematically collected and 42 studies meeting our inclusion criteria were analyzed. The model-selection approach was used to determine the optimal…

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…

This report presents a review of the statistical practices of 30 journals representative of the second language field. A review of 150 articles showed a number of prevalent statistical violations including incomplete reporting of reliability, validity, non-significant results, effect sizes, and assumption checks as well as making inferences from…

This article reports the first meta-analysis of the L2 motivational self system (Dörnyei, 2005, 2009). A total of 32 research reports, involving 39 unique samples and 32,078 language learners, were meta-analyzed. The results showed that the three components of the L2 motivational self system (the ideal L2 self, the oughtto L2 self, and the L2…

Second language (L2) anxiety has been the object of constant empirical and theoretical attention for several decades. As a matter of both theoretical and practical interest, much of the research in this domain has examined the relationship between anxiety and L2 achievement. The present study meta-analyzes this body of research. Following a…

In the present article, we explore the extent to which previous research on register variation can be used to predict spoken/written task-type variation as well as differences across score levels in the context of a major standardized language exam (TOEFL iBT). Specifically, we carry out two sets of linguistic analyses based on a large corpus of…

The importance of vocabulary, its types, selection criteria, size and depth, and teaching principles were found unclear. The present article seeks to respond to such challenge. To achieve the mentioned goals, we did a systematic review to previously related studies and theories. The results showed that the vocabulary was found to be more…

There has been a consensus in research and practices that social and cultural aspects of lives contribute to literacy development, particularly in second language learning. The conception of literacy has been shifting from the lens of formal literacy learning in school settings into broader opportunities in sociocultural contexts, and some may…

A meta-analysis was conducted to examine the construct validity of language aptitude by synthesizing the existing research that has been accumulated over the past five decades. The study aimed to provide a thorough understanding of the construct by aggregating the data reported in the primary research on its correlations with other individual…
