Research on the implementation of CLIL at the onset of primary school is limited and has largely overlooked the role of other sources of individual differences. This study investigated the effects of the CLIL approach to English learning, together with the effects of out-of-school exposure to the language through media and other sources of…

In this study, we investigated how student engagement and disengagement change over the course of a semester in the L2 classroom. We modeled change at the inter- and intra-individual levels, using time-variant predictors to examine differences in student classroom engagement and disengagement trajectories. In addition to these temporal dynamics,…

One of the important components in second language (L2) development is to produce clause-level units of form-meaning pairings or argument structure constructions. Based on the usage-based constructionist approach that language development entails an ability to use more diverse, more complex, and less frequent constructions, this study tested…

Most common words in English have multiple different meanings, but relatively little is known about why children grasp some meanings better than others. This study aimed to examine how variables at the child-level, wordform-level, and meaning-level impact knowledge of words with multiple meanings. In this study, 174 children aged 5- to 9-years-old…

This cross-sectional study addresses for the first time the non/linear association between individual learner differences of social, proficiency-related, and socioaffective nature (length of residence [LoR], varietal proficiency, exposure, and socioaffect) and differential outcomes in L2 sociolinguistic repertoires against the backdrop of the…

This study examined whether vocabulary knowledge is sufficient for second language (L2) word-meaning inferencing. Specifically, it investigated the role of the learner's sensitivity to a word's morphological structure (referred to 'morphological awareness' or 'MA' hereafter) as additional support that enhances multi-character word-meaning…

Lexical items that are encountered more frequently and in varying contexts have important effects on second language (L2) development because frequent and contextually diverse words are learned faster and become more entrenched in a learner's lexicon (Ellis 2002a, b). Despite evidence that L2 learners are generally exposed to non-native input,…

It is well known that successful second language (L2) learners are motivated individuals. Accordingly, L2 researchers have tested the predictive power of different motivational constructs on language learning outcomes. However, this perspective appears to neglect the assessment of achievement as a predictor of future motivation. To assess this…

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…

Communicative adequacy is a key construct in second language research, as the primary goal of most language learners is to communicate successfully in real-world situations. Nevertheless, little is known about what linguistic features contribute to communicatively adequate speech. This study fills this gap by investigating the extent to which…

Among predictors of second language (L2) reading, both first language (L1) reading and L2 listening embody the complexities of comprehension ability in their construct. Their contributions to L2 reading have rarely been examined together, probably because of the different theoretical frameworks in which they are postulated. Therefore, the field…

Language aptitude remains one of the most understudied predictor variables in L1 attrition research. The current study seeks to address this gap by investigating the effects of language aptitude on L1 retention in late attriters. Forty L1 Spanish-L2 Swedish bilinguals living in Sweden participated in the study, along with 20 functionally…

Most of the world's population has knowledge of at least two languages. Many of these bilinguals are also exposed to and identify with at least two cultures. Because language knowledge enables participation in cultural practices and expression of cultural beliefs, bilingual experience and cultural identity are interconnected. However, the specific…

The article summarizes results from two experimental studies (N = 23, N = 21) investigating the extent to which working memory capacity (WMC) intervenes in "ab initio" language development under two pedagogical conditions [± grammar lesson + input-based practice + explicit feedback]. The linguistic target is the use of morphosyntax to…

The present study focuses on the influence of starting age and input on foreign language learning. In relation to starting age, the study investigates whether early starters in instructional settings achieve the same kind of long-term advantage as learners in naturalistic settings and it complements previous research by using data from oral…
