The revised Speech Learning Model (SLM-r) postulates that learners with more precisely defined categories in their native language (L1) exhibit greater proficiency in acquiring sounds in a second language (L2). Despite its recent emergence, empirical studies validating this hypothesis remain scarce. This study aims to investigate the predictive…

We investigated whether sign-naïve learners can infer and learn the meaning of signs after minimal exposure to continuous, naturalistic input in the form of a weather forecast in Swedish Sign Language. Participants were L1-English adults. Two experimental groups watched the forecast once (n = 40) or twice (n = 42); a control group did not (n =…

Previous studies have suggested that deafness could lead to deficits in motor skills and other body-related abilities. However, the literature regarding motor skills in deaf adults is scarce and existing studies often included participants with heterogeneous language backgrounds and deafness etiologies, thus making it difficult to delineate the…

Previous research has indicated that explicit information (EI) about either the first language (L1) or second language (L2) along with task-essential practice can facilitate L2 learning (e.g., Fernández, 2008; McManus, 2022). However, little research has examined L1--L2 contrastive EI with L1/L2 practice. Targeting plural-marking accuracy, the…

Most U.S. colleges and universities expect students to improve their writing ability by taking first-year composition (FYC) courses. In such courses, non-native English (L2) writers with diverse language backgrounds study alongside their native English (L1) speaking peers. However, it is not clear how different these populations are in terms of…

This study aims to provide a comprehensive profile of collocational competence, a key component of one's overall linguistic competence. For the maximum of ecological validity, we elicited naturalistic oral/written production data from 84 Chinese intermediate EFL learners and performed a 2×2 fashion of analysis on their performance in each of the…

Relative clauses have long been examined in research on first (L1) and second (L2) language acquisition and processing, and a large body of research has shown that object relative clauses (e.g. 'The boy that the girl saw') are more difficult to process than subject relative clauses (e.g. 'The boy that saw the girl'). Although there are different…

Individuals differ in their ability to perceive and learn unfamiliar speech sounds, but we lack a comprehensive theoretical account that predicts individual differences in this skill. Predominant theories largely attribute difficulties of non-native speech perception to the relationships between non-native speech sounds/contrasts and…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

Derivational suffixes are known to play a crucial role in assigning stress to multi-syllabic words among native English speakers. However, it is unclear whether second language (L2) learners of English can effectively use derivational suffixes as stress cues in written words. To address this gap, we studied if native Chinese-speaking adults…

Modifying and hedging one's claims appropriately is an important characteristic of academic writing. This study focuses on the three main English modal verbs used to express "epistemic possibility" to avoid making strong statements, viz., "may", "might", and "could". The purpose of this corpus-based study is…

Challenges in reading Chinese as a foreign language involve the large proportion of two-character compound words which have complex intra-word morphological structures and scriptal distance between learner's native language (L1) and Chinese as a second or foreign language. This study extended a previous investigation on the processing of Chinese…

This study examined whether the linguistic distance between the first (L1) and second (L2) language is a significant determinant of L2 writing skills of 292 adult immigrants from 39 different source countries, who were beginner learners of Spanish L2. Gender, age, length of residence in Spain, education level as a proxy for literacy skills in L1,…

Despite the growing interest in AI for language assessment, there remains a significant research gap regarding its usefulness for assessing less proficient language skills, particularly those of learners of English as a second or foreign language (S/FL). AI models often prioritize proficient writing, neglecting the intricacies of learner language.…

In this study, we examined the effect of previewing unfamiliar vocabulary on the real-time reading behavior of first language (L1) and second language (L2) readers. University students with English as their L1 or L2 read passages with embedded pseudowords. In a within-participant manipulation, definitions of the pseudowords were either previewed…
