This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

In L1 attrition research, it's recognized that a previously acquired language can transform under the influence of a newly acquired one. However, the precise L1-L2 relationship is intricate and warrants further study. Some research suggest that L2 mastery might reduce L1 proficiency, while others show that both languages can be maintained. Age of…

Verbal Fluency (VF) task total scores are widely used in language attrition studies, but they do not provide insight into the processes underlying optimal performance. We analyse the efficacy of clustering (subcategories within a category) and switching (shifting between these subcategories) strategies in phonemic (PVF) and semantic (SVF) tasks.…

This article sheds light on the linguistic and extralinguistic conditions that determine the likelihood of L1 grammatical attrition in late sequential bilinguals. We explore whether aspectual interpretations associated with the present tense may be a vulnerable area for the native grammar of 30 late Spanish-English bilinguals who have settled in…

With the rapid implementation of early foreign language programmes in the state of North-Rhine-Westphalia, Germany, first for Grade 3 (ages 8-9 years) in 2003 and then from Grade 1 (ages 6-7 years) in 2008, primary school teachers had to adapt to teaching a foreign language in Grade 1 quickly. Teachers had little experience with language teaching…

In the vast literature on language attrition, studies on the role of extralinguistic factors in language retention, particularly concerning foreign language (FL) skills acquired in formal instructional contexts, are scarce. We address this issue by focusing on the impact of the frequency of FL use, both extramural and in the classroom, and…

The number of students embarking on a study abroad experience continues to grow steadily. A new setting for study abroad in English has developed recently where students may be studying in an environment where English is used as a lingua franca but is not an official language of the country. This setting is referred to as English as a lingua…

Despite the extensive research on bilingual development, our understanding of how lexical competition unfolds in the bilingual mind remains limited. Previous studies have predominantly focused on crosslinguistic competition, neglecting the examination of the competition process within each language and the influence of diverse bilingual…

This study highlights critical factors influencing English as a Foreign Language (EFL) teachers' decisions to provide in-class oral corrective feedback (OCF). It explores the interplay between teachers' individual differences -- namely educational background, teaching experience, and additional training -- and their decisions regarding OCF. EFL…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

Collaboration in peer interaction has been investigated extensively by analysing language-related episodes (LREs). These have been classified variously depending on the nature of the discourse. Most studies of collaboration in peer interaction have thus tended to adopt a predetermined framework for analysis. Meanwhile, task type as a mediating…

This study investigates the use of overt and null subjects in Bulgarian in child heritage speakers with L2 German. The alternation of overt and null pronominal subjects in null-subject languages like Bulgarian depends on grammatical and discourse conditions and contrasts with German. Oral narratives were elicited in Bulgarian, comparing the…

This study examines the knowledge representation of Japanese university students assessed using grammaticality judgement tests (GJTs) and a metalinguistic knowledge test (MKT). The study also investigates the role of automatised and non-automatised explicit knowledge in general L2 language proficiency. Participants were 87 late learners of English…

Task-based language teaching (TBLT) emerged in the 1980s as a learner-centred and experiential alternative to more established and teacher-led approaches to acquiring an additional language (L2). Two decades ago, a paper published in "The Language Learning Journal" discussed the advantages and drawbacks of TBLT that had become apparent…

The instrumental motivations of learners of English as a foreign language (EFL) have been examined in detail, but there is a lack of studies exploring how they compare to those of learners of other languages (LOTEs). To address this gap, this study draws on a questionnaire (N = 312) and on semi-structured interviews (n = 20) and focuses on…
