Given that both spoken and written language are subject to corruption from speech errors, disfluencies, and environmental noise, successful language comprehension sometimes requires deriving a non-veridical understanding of the linguistic input. Recent work has demonstrated that these non-veridical understandings are not merely semantic, but that,…

During language acquisition, children are tasked with the challenge of determining which words can appear in which syntactic constructions. This has been long recognized as a learnability paradox. On one hand, there are generalizations that children must learn. On the other hand, language is known for its arbitrariness, so children also need to…

In this dissertation I investigate the Mandarin "you"-existential sentence. My focus is on its syntax. I also discuss in less detail some semantic peculiarity of the "you"-existential. I begin my investigation of the syntax of "you"-existentials by first looking into what they are not. To this end, I present five…

Proficient reading requires the ability to analyze words for various properties, including pronunciation, meaning, and syntactical function. However, most instruction in word analysis is limited to phonics instruction provided in the early elementary grades. For older students, whose words largely center units of meaning, or morphemes, early…

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,…

This dissertation is about the learnability of different generative, Separationist approaches to nominal morphosyntax. The core of my investigation is number, gender, and declension class, as manifested across nouns, adnominals (adjectives, numerals, demonstratives, and quantifiers), and articles. An extreme position would require that all of…

Speakers display considerable variability in language use and representations: they may have different pronunciations of the same word, different intended meanings for the same phrases, and different sets of syntactic constraints in their internalized grammars. Comprehenders adapt to such variability by constantly updating their expectations for…

Learning to write programs is hard, but many fail to even learn basic program reading skills, such as mentally tracing a program to predict its behavior. This dissertation argues a new theory of programming language knowledge that includes mappings from syntax to semantics and their nested combinations can serve as the basis for more granular…

This thesis investigates the choice between reflexive pronouns (e.g., "herself") and personal pronouns (e.g., "her") in the expression of subject coreference in English locative prepositional phrases. A persistent puzzle for syntactic theories of pronoun licensing, commonly known as binding theories, it has long been observed…

This dissertation sets out to find an answer to the question why not all logically conceivable patterns are found typologically. In other words, my aim is to find paradigmatic gaps and explain their absence. In doing so, I use the mathematical notion of monotonicity (which is a more general term to convey order preservation) as proposed by Graf…

The Portuguese present perfect (P-PP) is an understudied topic in the field of generative language acquisition. In the past decade, Third Language Acquisition (L3A) has enjoyed special attention in studying how multilingualism works. Researchers have concentrated on the examination of the source of transfer at the initial stages. However, there is…

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…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

How do children learn the meaning of words like "pretty" and "tall," which are not only gradable and context dependent (Kennedy & McNally 2005), but encode speaker subjectivity? Despite their complex semantics (Stephenson 2007; Lasersohn 2009; Bylinina 2014), these and other adjectives like them, are some of the most…
