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…

Although research on content and language integrated learning (CLIL) has shown that CLIL instruction may enhance students' second or foreign language learning compared to regular foreign language instruction, there are also studies that have indicated similar language development between CLIL and non-CLIL students. However, CLIL can be organized…

Knowledge of derivational affixes makes an important contribution to second language learners' success when reading. Yet while the effects of some learner variables (L2 proficiency, L1 background) have been investigated, there has been little research addressing the effects of varying characteristics of affixes on their acquisition. The goal of…

This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

This study explored the effects of listening-based lexical focus-on-form (lexical FonF) on the acquisition and retention of morphologically complex words. One hundred eighty-two adult English learners with two levels of English proficiency (higher and lower proficiency) from a public university in mainland China were assigned to three different…

Most deaf children have hearing parents who do not know a sign language at birth and are at risk of limited language input during early childhood. Studying these children as they learn a sign language has revealed that timing of first-language exposure critically shapes language outcomes. But the input deaf children receive in their first language…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Research into vocabulary knowledge often differentiates between breadth (how many words a person knows) and depth (how well the words are known). Both theoretical categories are essential for understanding language learners' lexical development, but how the different aspects of vocabulary knowledge interconnect has not received the same attention…

The study aims to determine whether exposing EFL Saudi undergraduate students to TED talks could effectively contribute to the improvement of their oral language proficiency. To achieve this goal, 32 English as a Foreign Language Saudi undergraduate students were recruited to participate in the study. These students were selected based on their…

This study investigates the use of formulaic sequences (FS) in academic writings of Chinese learners of English as a foreign language across different levels of studies at a public university in China. Frequency-based formulas were retrieved from a corpus of student academic texts written at five time points between Year 1 and Year 3. The…

As the global educational landscape undergoes rapid transformation, "Education 4.0" emerges as a cutting-edge paradigm that harnesses advanced technologies to revolutionize the learning process. This study investigates the impact of Education 4.0 on improving English proficiency among engineering students in Dhaka, Bangladesh. Using a…

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor…

The current study set out to examine to what degree age of acquisition (AOA), defined as a learner's first intensive exposure to a second language (L2) environment, mediates the final state of postpubertal, spoken vocabulary attainment. In Study 1, spontaneous speech samples were elicited from experienced Japanese users of English (n = 41) using…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

This tutorial offers speech-language pathologists (SLPs) an opportunity to consider the theoretical constructs of language acquisition theory and the multifactorial determinants that can impinge on the language acquisition process for children with complex communication needs. The system of constraints observed through the lens of optimality…
