Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46)…

The present study explored the relationship between amount of dual language exposure, parents' language quality and bilingual competence among Chinese American children with autism spectrum disorder by using a cross-sectional correlational design. Thirty parent-child dyads participated in this study. Survey and observational data were collected…

This study reports on anxiety, enjoyment, and breakdown fluency of L2 English learners under the monologue and dialogue conditions using an idiodynamic approach. Eight Mandarin-speaking undergraduates from a top university in China voluntarily participated in the study, with half completing in a monologue condition and the other half in a dialogue…

While it has been shown that socioeconomic status (SES) is important for children's literacy development in their first language (L1), less is known about its association with reading in a second language (L2). The present study examined the different effects of SES on the acquisition of reading in Chinese as L1 and English as L2 from ages 7 to…

This paper explores the number marking challenges faced by L2 learners of English whose L1 is one of the classifier languages Mandarin Chinese (henceforth Chinese) or Bahasa Indonesia (henceforth Indonesian). It examines whether these groups differ in their marking of English number, and how the speaker's level of proficiency, as well as…

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 examines the developmental relationship between L2 Chinese oral fluency and self-repair in Dutch students learning Chinese. In this study, 76 junior Dutch students were split into two different groups based on level and were tested at two time periods (T1 and T2) for L2 Chinese fluency, which included the control variables of repetition…

In this dissertation, I investigated how cognitive resources as well as formal, and informal language experience impact language learning in two studies. In the first study (Chapter 2), I examined the learning of Spanish grammatical gender by Chinese international students who were studying abroad in the US. The goal of that study was to uncover…

How could individual differences in processing non-speech acoustic signals influence their cue weighting strategies for L2 speech contrasts? The present study investigated this question by testing forty L1 Chinese-L2 English listeners with two tasks: one for testing the listeners' sensitivity to pitch and temporal information of non-speech…

This study investigated English first language (L1) speakers' motivation for learning Chinese as a second language (L2) in Australia and the links of underlying motivational components to learner sociobiographical (e.g. gender and reasons for learning) and language learning variables (i.e. experience abroad, hours of self-study, and speaking with…

Literacy and mathematics have been shown to be related to each other across languages, ages, and levels of proficiency (e.g., [5, 11, 6, 19, 29, 35, 39, 43, 46, 49, 53, 57]). More specifically, math instruction is further complicated and becomes more difficult when occurring in a non-native language of instruction (e.g., [2, 8, 16, 18, 20, 31, 41,…

A growing body of research has provided evidence for the foreign language effect on thinking, notably decision-making. Our prior work found reduction of recency effect following positive feedback in a foreign language as compared to the native tongue during even-probability gambling. However, the fundamental mechanisms underlying this effect…

This study explored the relationship between metapragmatic knowledge and transfer of learning from one speech act to another. Using a digital application, 105 Chinese learners of English received implicit instruction on how to formulate a high-imposition request to someone in a higher social status and larger social distance. Immediately after the…

The present study compared bilingualism with bidialectalism in their respective impact on executive control, using a short-term language switching training paradigm for participants who were both bidialectals (Shanghainese-Mandarin Chinese) and bilinguals (Chinese-English). Twenty participants were assigned to a control group where no language…

The dissertation focuses on the Chinese literacy experiences of different generations of Thai Chinese families in Thailand, spanning periods characterized by varying ideologies toward the Chinese language, which have either constrained or facilitated its acquisition. This qualitative work examines how evolving national policies and international…
