Purpose: As evidenced by perceptual learning studies involving adult listeners and speakers with dysarthria, adaptation to dysarthric speech is driven by signal predictability (speaker property) and a flexible speech perception system (listener property). Here, we extend adaptation investigations to adolescent populations and examine whether adult…

Language learning activities involving time-pressured repetition of similar content have been shown to facilitate improvements in fluency. However, concerns have been voiced about whether these gains might be offset by reduced levels of grammatical accuracy. This descriptive study tracked the oral proficiency of 32 Japanese university students…

The current study reported an empirical investigation that tested the collective and individual effects of morphological awareness and cognate awareness on Japanese word learning among Chinese learners of Japanese. 131 Chinese learners of Japanese participated in this study. They completed morphological awareness measurements (morpheme…

When making memory predictions (judgments of learning; JOLs), people typically underestimate the recall gain across multiple study-test cycles, termed the underconfidence-with-practice (UWP) effect. This is usually studied with verbal materials, but little is known about how people repeatedly learn and monitor their own actions and to what extent…

This research aimed to determine the impact of the effectiveness in the application of an independent method of teaching students on their progress in achieving a certain level of Japanese. The study used key methods that implied the experimental involvement of 60 3rd- and 4th-year American and Chinese students with the N3 and N2 levels of…

This study investigates the effects of multilingualism and the degree of proficiency in different languages on vocabulary knowledge among Spanish language learners. Participants completed a 160-word meaning recall test designed to measure their knowledge of the 8,000 most frequent Spanish words and a self-assessment questionnaire on their…

This study investigated how much practice is necessary for learners to attain durable second language (L2) grammar knowledge. Using digital flashcards, 119 participants practiced translating 12 sentences into an artificial language, followed by feedback, until they had typed all sentences correctly. Participants repeated this activity in one, two,…

In this exploratory mixed-methods study, we introduce and test our AI-powered vocabulary learning system--ARCHe, which embeds four AI functions: (1) automatic feedback towards for pronunciation, (2) automatic feedback for towards handwriting, (3) automatic scoring for student-generated sentences and (4) automatic recommendations. Specifically, our…

Despite the substantial expansion in vocabulary research since the 1980s, we still know very little about how vocabulary develops over time and what factors influence this development. This methodological overview discusses key issues and considerations in vocabulary breadth growth assessment to help advance research in this area. The report…

Languages differ regarding the depth, structure, and syntactic domains of recursive structures. Even within a single language, some structures allow infinite self-embedding while others are more restricted. For example, when expressing ownership relation, English allows infinite embedding of the prenominal genitive "-s," whereas the…

Extramural exposure, through activities such as watching TV, gaming, networking, and online reading, has become an important source of vocabulary acquisition in English as a foreign language, particularly when learners' first language (L1) has many cognates with English. Our study examined extramural vocabulary acquisition of 10th-grade L1…

In recent years, there has been considerable interest in how to maximize learners' retention of multiword expressions. One technique that has been shown to be highly effective is the use of exercises such as those found in mainstream English as a second language textbooks. In the present study, we investigated how the execution of a gap-fill…

The purpose of this study was to examine the effectiveness of explicit corrective feedback (CF) strategies (i.e., metalinguistic feedback and explicit correction) versus implicit CF methods (i.e., recasts and explanation questions) in helping English language learners acquire the that-trace filter. To this end, one hundred twenty intermediate…

The continuous growth of production and the development of new video games have influenced many aspects of human lives, particularly the young generation. While video games may tap on the entertainment side, primarily aiming to entertain players, they may profoundly impact multi-literacy development. This qualitative study utilizes narrative…

This paper probes into implicit language aptitude (LA), a set of cognitive abilities that showcase learners' unconscious, automatic second language (L2) attainment. Implicit LA is becoming an important part of aptitude research, and advances the understanding of L2 learning mechanism. This paper critiques the construct of implicit LA and proposes…
