In standard models of language production or comprehension, the elements which are retrieved from memory and combined into a syntactic structure are "lemmas" or "lexical items". Such models implicitly take a "lexicalist" approach, which assumes that lexical items store meaning, syntax, and form together, that…

Eventualities have been recognized as psychologically and linguistically relevant for more than 50 years. Psychologically, eventualities are complex bundles of information derived from our perceptions of the world. The question for linguists is how much of this complexity is reflected in our eventuality-denoting lexical entries and the…

In this dissertation, I examine how fingerspelled words and core signs in American Sign Language (ASL) reduce as they are repeated. This investigation is motivated by theories of language production that posit that reduction may be shaped not only by reducing articulatory effort, but also by accommodation to an interlocutor's understanding of the…

The present dissertation examined the initial state of L3 phonology in native speakers of French and German who were Spanish-English bilinguals. The present work analyzed perception (Chapter 3), production (Chapter 4) and the perception production interface (Chapter 5). The results revealed that these bilinguals are influenced by both of their…

Over a century ago, rhetoricians called on writing instructors in the U.S. to accept and even encourage language diversity among learners. Yet scholars of composition, rhetoric, and writing studies are still advocating for this via arguments for linguistic justice and translingualism, even referring to strict adherence to a single, mainstream…

The interpretation of numerals has been traditionally debated across disciplines including, but not limited to, Linguistics, Developmental Psychology, and Philosophy. A big portion of the debate concentrates on the ontology of numerals, i.e., their basic meaning, and the mechanisms by which (non) exact interpretations (e.g., at least) are derived.…

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…

In this thesis, I use a combination of simulations and empirical data to demonstrate that a small set of structural and functional principles - the basic tenets of predictive coding theory - succinctly accounts for a very wide range of properties in the language processing system. Predictive coding approximates hierarchical Bayesian inference via…

Language comprehension requires a complex series of decisions under uncertainty. This is especially obvious when one string may have multiple different interpretations, whether due to lexical ambiguity, or the potential for an inference beyond literal content. This dissertation profiles how the human system for language comprehension times those…

Scholars have examined and debated the use of African American Language (AAL) in the past but research that has focused on its use in college settings has been scarce. This study uses a case study approach to examine attitudes and perspectives of a university community toward AAL use inside and outside the classroom and beyond. The case study…

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,…

Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

This dissertation explores the role of memory in language processing, and specifically how interference during lexical encoding can result in downstream interference during retrieval. The dissertation merges insights from both the sentence processing literature as well as the study of memory in non-sentential contexts and focuses on two factors…

The incorporation of empirical and theoretical knowledge from the language acquisition literature into formal diachronic syntax has been largely exiguous despite the growth of the latter as a subfield in formal linguistics over the past thirty years. In this dissertation, it is shown that a greater knowledge of diachronic phenomena, particularly…

This dissertation interrogates the representation of syntactic locality constraints, specifically intervention locality, within child grammar. Our focal point is the Intervention Hypothesis, which suggests that children are governed by a strict version of featural Relativized Minimality, leading to comprehension difficulties when partial featural…
