While much of the existing literature on code-switching focuses on languages that differ typologically, this dissertation focuses on typologically similar languages. Code-switching between Mandarin and Taiwanese is examined through the perspectives of 1) sociolinguistics, 2) typology, 3) phonetic and phonological production, and 4) speech…

Chinese is a highly complex language with internal variation unprecedented in most other languages. Yet, that does not mean Chinese is unique in the sense that it cannot be compared to other languages and new concepts need to be introduced for the description of it. This paper is dedicated to the question of how to apply the notion of…

How does linguistic structure affect children's developing cardinal number knowledge? The bootstrapping theory proposes that children might use syntactic information provided by known words such as quantifiers to bootstrap the meanings of unfamiliar words such as number words. Prior studies of numeral and quantifier development have indicated that…

The human ability to anticipate upcoming behavior not only enables smooth turn transitions but also makes early responses possible, as respondents use a variety of cues that provide for early projection of the type of action that is being performed. This article examines resources for projection in interaction in three unrelated…

This study investigates how L1 and L2 users of Mandarin perceive a rare construction in Mandarin that involves interpreting an NP in the object position as a location argument or instrument argument instead of as a theme/patient argument. For example, "kai zuoshou" (literally "drive left-hand") has been used to mean "use…

This paper addresses the complexity of the linguistic situation in China by examining the language policy and language categorisation in the People's Republic of China (PRC), which has implications for how multilingual speakers conceptualise and practice 'language'. In addition, this paper examines the conceptual framework of translanguaging and…

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…

This dissertation represents the first attempt to integrate typological, semantic, and psycholinguistic perspectives to elucidate a semantically "bizarre" and "illogical" phenomenon called "expletive negation" (henceforth, EN) which is well known in Romance languages but has so far attracted little attention outside…

Previous research indicates that infant-directed speech (IDS) is usually slower than adult-directed speech (ADS) and mothers prefer placing a focused word in isolation or utterance-final position in (English) IDS, which may benefit word learning. This study investigated the speaking rate and word position of IDS in two typologically-distinct…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

This paper investigates the phonology of L2 speech and its impact on intelligibility in English as a Lingua Franca (ELF) contexts. Many studies have considered speaker-related characteristics, such as speech styles and pronunciation features, that influence the intelligibility of L2 speech for both nonnative speakers (NNS) and native speakers…

By replicating Cho (2017), this article investigates how second language (L2) learners with an article-less first language acquire two types of English definiteness, anaphoric and nonanaphoric. Mandarin Chinese, as an article-less language, has a demonstrative determiner that shares the same feature set as the English definite article…

This study uses both offline and online tasks in order to investigate whether second language learners of English from an article-less first-language (Mandarin) are able to integrate the indefinite article into their grammar despite the lack of articles in their first language. This article reports on two studies, one on learners' sensitivity to…

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…

Producing a sensible utterance requires speakers to select conceptual content, lexical items, and syntactic structures almost instantaneously during speech planning. Each language offers its speakers flexibility in the selection of lexical and syntactic options to talk about the same scenarios involving movement. Languages also vary typologically…
