Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and…

Current L2 utterance fluency literature tends to operationalize disfluency as isolated, individual features. However, disfluency features often co-occur at one location or across multiple locations in one utterance. This study explores the co-occurrence of L2 disfluency features in a speech corpus from 71 L1 and L2 speakers of English across…

This study examined the influence of cognate status and language distance on simultaneous bilingual children's vocabulary acquisition. It aimed to tease apart effects of word-level similarities and language-level similarities, while also exploring the role of individual-level variation in age, exposure, and nontarget language proficiency. Children…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

This study aims to investigate ChatGPT's ability to comprehend input from nonnative speakers, specifically those learning English as a second language, with Japanese speakers serving as the model population. The experiment examines how ChatGPT evaluates the difficulty levels of the Test of English for International Communication (TOEIC), which is…

This study investigates the relationship between identification with the local territory, language attitudes and language proficiency in young immigrants in Catalonia, a region in Spain. The aims of the study are to examine how identification with the local territory affects attitudes and proficiency in languages, and whether language attitudes…

Studies have shown that raising L2 learners' metaphor awareness contributes to the acquisition of figurative language, which fosters students' development of language skills. However, the instruments measuring metaphor awareness, in the majority of relevant research, did not seem to have undergone proper methodological procedures for checking…

Scores of different language tests intended for similar purposes (e.g., admission to higher education) are used to determine candidates' language proficiency and readiness for a chosen domain. To be fair to all students irrespective of the test they took, score requirements should be comparable. Score concordance tables provide an empirical basis…

A writer's L1 is generally believed to influence their L2 English writing significantly. However, the extent to which L1 backgrounds influence Asian learners' L2 English writing has not been wholly elucidated due to the lack of data covering various learners in Asia. Therefore, this study analysed more than one-million-word essays written by 2,318…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…

In most universities in South Africa, English is still preferred as the medium of instruction. However, most schools in South Africa have adopted a home-language education approach. Those school students then have a lower English proficiency compared to other students from English schools. Providing these students with instructional assistance…

Language teachers cannot help their students develop high levels of metalinguistic knowledge and language aptitude if they themselves are found lacking in these abilities. This article reports on a study that utilised a descriptive correlational mixed-methods research design to gather data from 89 multilingual teachers of English, Chinese, French,…

The present study investigates L1 and L2 English speakers' knowledge of the "wh"-clausal construction along the parameters of (a) conventionality, distinguishing between high-frequency conventional and low-frequency unconventional formulations ("I asked him why they agreed/why did they agree"), and (b) proposition type,…

This study examines Korean L2 learners' production of English phonological contrasts (e.g., consonant-final versus vowel-final forms) that are absent in their L1. Twenty university students divided into high- and low-proficiency groups participated in the study. Their productions were analyzed for segmental accuracy and error patterns. Results…

Complexity, accuracy, and fluency (CAF) as measures of language proficiency have been used extensively in assessing second language production in English language studies related to task-based language teaching. The present review adds the following critical elements to the existing body of literature: (i) Provides synthesis and critical analysis…
