The study aimed to explore the evidence of first language (L1) mediation in second language (L2) word associations and the L2 learner-related factors affecting the extent of L1 mediation with the following approaches. First, different from previous research, word association tests (WATs) embraced both receptive and productive word associations in…

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…

In order to better understand the role of syntactic similarity in a code-switched sentence, the current study explored the effect of similar and different syntactic structures on Chinese-English bilinguals' intra-sentential switching costs. L2 proficiency and switching directions as factors that potentially intervene in bilingual performance were…

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…

English-medium instruction (EMI) has burgeoned alongside two decades of L2 self-regulated learning research. In both areas, listening remains under-researched, longitudinal designs are under-employed, and in-depth studies are necessary to unpack learner development. In a context believed to initiate self-regulated learning, the current study…

This project examined the acquisition of third person accusative clitics in Spanish by Chinese-speaking learners. Specifically, it focused on the role of cross-linguistic influence and patterns of language exposure and use in the acquisition of the syntactic and semantic properties constraining the production and intuition of overt and null…

This study is aimed to identify the effects of task complexity on first language (L1) use and the functions it may serve when two groups of learners of English as a foreign language (EFL) work on collaborative tasks. Twenty-four pairs of Chinese EFL learners from two universities were assigned to a lower-proficiency and a higher-proficiency group,…

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…

The present study used a repetition priming paradigm to investigate the basic morphological units stored in mental lexicon for Chinese as second language learners (L2) and Chinese native speakers (L1). Meanwhile, the modulation of Chinese morpheme property (bound or free) in lexical processing was examined. The results revealed that for…

We investigated the role of cue weighting, second language (L2) proficiency, and L2 daily exposure in L2 learning of suprasegmentals different from the first language (L1), using eye-tracking. Spanish monolinguals, English-Spanish learners, and Mandarin--Spanish learners saw a paroxytone and an oxytone verb (e.g., "FIRma-firMÓ"…

This dissertation contributes new data to the debate on the source and manner of transfer in third language (L3) acquisition. The "L1 Status Factor" (L1SF, e.g., Hermas, 2010; Leung, 2002; Lozano-Pozo, 2003) maintains that the transfer source is the native language (L1), whereas the "L2 Status Factor" (L2SF, Bardel & Falk,…

The relationship between language switching and task switching has been well studied in bilingualism literature. This study employs novel experiments involving magnitude-parity switching and transparency-orientation switching and compares the costs associated with these two types of task switching with language switching. Switching costs and the…

This study delves into the predictors of English proficiency among middle school students in China, utilizing the rich dataset provided by the China Education Panel Survey (CEPS). By integrating multilevel modeling and Support Vector Regression (SVR), this research scrutinizes a broad spectrum of factors at the individual, family, class, and…

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N = 283, 5-10 years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language…

This study proposed an innovative automated approach to differentiation of the vocabulary proficiency of Chinese speakers. A robust K-means algorithm was designed to compare the oral proficiency between L1 and L2 Chinese speakers regarding lexical richness and how relatively effective the various lexical measures were in performing the…
