This dissertation features a relative clause island, whose status has been known to differ significantly across languages and extraction types. By conducting a series of acceptability judgment experiments with human participants, as well as measuring token-by-token surprisal values among large language models, I demonstrate the following: First,…

In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

Research on modality shifts in English-to-Chinese courtroom translation remains limited, despite the critical role of modality in shaping legal nuance, and speaker intentionality in judicial settings. This gap is particularly consequential in high-stakes contexts such as the International Military Tribunal for the Far East (IMTFE), where…

Linguistic meaning is generated by the mind and can be expressed in multiple languages. One may assume that equivalent texts/utterances in two languages by means of translation generate equivalent meanings in their readers/hearers. This follows if we assume that meaning calculated from the linguistic input is solely objective in nature. However,…

The present study investigates L1 and L2 English speakers' knowledge of the "wh"-clausal construction along the parameters of (a) conventionality, distinguishing between high-frequency conventional and low-frequency unconventional formulations ("I asked him why they agreed/why did they agree"), and (b) proposition type,…

Data-driven learning uncontroversially plays a role in human language acquisition--how large a role is a matter of much debate. The success of artificial neural networks in NLP in recent years calls for a re-evaluation of our understanding of the possibilities for learning grammar from data alone. This dissertation argues the case for using…

This study examines how English has penetrated the Korean language by analyzing Anglicisms in weekly news magazine articles, with special reference to translation as a mode of language contact. For this purpose, it conducts a diachronic quantitative analysis of the occurrence of Anglicisms by compiling and utilizing corpora consisting of…

The present study investigates the Thai quantifier 'laay' ([Thai characters omitted]) and its two major English lexical equivalents: 'several' and 'many', using data from an English-Thai parallel corpus, the Thai and British National Corpora. An examination of the parallel corpus reveals that the quantifier 'laay' has a broad semantic property as…

Grounded or embodied cognition research has employed body-object interaction (BOI; e.g., Pexman et al., 2019) ratings to investigate sensorimotor effects during language processing. We investigated relationships between BOI ratings and nonarbitrary statistical mappings between words' phonological forms and their syntactic category in English;…

We examine the second language (L2) acquisition of variable Spanish word order by first language (L1) speakers of English via the acquisition of unaccusative and transitive predicates in various focus-related contexts. We employ two bimodal linguistic tasks: (1) acceptability judgment task (B-AJT) and (2) appropriateness preference task (B-APT).…

Indices of lexical diversity have been used to estimate the size of a writer's vocabulary and/or a writer's lexical proficiency for some time. One issue with many commonly used indices of lexical diversity (e.g., TTR and index) is that they vary as a function of text length. Accordingly, much research has been devoted to the development of indices…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

This study compares monolinguals and different kinds of bilinguals with respect to their knowledge of the type of lexical phenomenon known as collocation. Collocations are word combinations that speakers use recurrently, forming the basis of conventionalized lexical patterns that are shared by a linguistic community. Examples of collocations…

In the context of English as a global language in which the interaction is not only between native speakers and ESL speakers but also among non-native speakers themselves, there is a need to investigate how well L2 listeners can judge and successfully comprehend accented English produced by other L2 speakers; particularly, how the specific…

The Information System for Vocational Decisions (ISVD) helps a person make decisions in choosing a vocation by collecting and processing data which include the following areas of information: college, career, military service, family, and the user's responses. It is vital that the machine be made to understand English--the natural language of the…
