The present study investigates bilinguals' capacity to rapidly establish memory traces for novel word forms in a second language (L2), as a function of L2 linguistic proficiency. A group of Chinese-English bilinguals with various English proficiency levels were presented with a reading-aloud task, consisting of 16 pseudowords and 16 English words…

Research Findings: This study investigated the effectiveness of a home-based intervention in increasing the intrinsic reading motivation and Chinese oral vocabulary of minority South Asian children in Hong Kong. A quasi-experiment was conducted with 78 children (M[subscript age] = 51.54 months; control: 37 children, intervention: 41 children) and…

Though Mandarin Chinese dual language immersion (DLI) has been growing rapidly in the U.S., research on this population is still rare. This study explored cross-language transfer of expressive oral vocabulary knowledge and definition skills among students in a Chinese DLI program. We found significant within and cross-language relationships of…

Chinese has a rich and diverse vocabulary of terms, especially verbs, expressing power relationships. This paper selected 25 power relationship terms from the Chinese Proficiency Scale for International Chinese Education, and used a true-false format to test the differences in acquisition between international students from Confucian cultural…

This brief report presents the results of a re-analysis of data by Yi, Man, and Maie (2023), who investigated L1 and L2 intuitive knowledge of phrasal frequency and collocation strength in multiword sequences. We utilized an individual-differences approach and examined which participant variables (age of onset, length of residence, language use,…

The current study examined the phonolexical processing of Mandarin segments and tones by English speakers at different Mandarin proficiency levels. Eleven English speakers naive to Mandarin, 15 intermediate and 9 advanced second language (L2) learners participated in a word-learning experiment. After learning the sound and meaning of 16 Mandarin…

This study investigates how academic disciplines impact second language (L2) lexical competencies. Prior L2 research has often overlooked the broader effects of disciplinary backgrounds on lexical development. To address this gap, this study utilized lexical decision, memory, and semantic fluency tasks to examine lexicon recognition, memory, and…

This study aimed to examine the effects of an AI-based object detection translation (AI-based ODT) application (app) on EFL students' vocabulary learning. We developed a system that utilized strategies to facilitate learners' vocabulary learning. The app applied dual code theory to present the objects in picture, word, and pronunciation formats.…

Research investigating the effect of study abroad on the development of grammatical accuracy has produced conflicting results. Using corpus linguistics research methods--yet to be used more extensively in SLA research--this study investigated students' acquisition of grammatical accuracy and lexical development during study abroad in China on data…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

This study examined the concurrent relations of English (EL) and heritage language (HL) proficiency to executive functions (EF) among low-income dual language learners (DLLs) from immigrant families. In a sample of 90 children (age = 38-70 months) from Chinese-speaking Chinese American and Spanish-speaking Mexican American families recruited from…

'Should I talk to my child in a language that I am not good at?' This question reveals the dilemma that many bilingual parents are facing.

We…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

This paper reports a case study focusing on naturalistic communication between a Chinese beginning non-native speaker of English (NNS) and an English native speaker (NS). The participants engage informally in a form of tandem learning, with each in turn taking the dominant role in the conversation through teaching the other vocabulary items in…
