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…

Bilinguals are able to compose expressions across their languages with seeming ease. This phenomenon, commonly referred to as "code-switching," has challenged both theoretical models in linguistics as well as neurobiological models of language processing. And yet, our models of the bilingual brain and the language processing mechanism…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

Language is one of the hallmarks of intelligence, demanding explanation in a theory of human cognition. However, language presents unique practical challenges for quantitative empirical research, making many linguistic theories difficult to test at naturalistic scales. Artificial neural network language models (LMs) provide a new tool for studying…

Just as pronouns like "she" and "he" make anaphoric reference to individuals, English words like "that" and so can be used to refer anaphorically to a proposition introduced in a discourse: "That's true; She told me so". Much has been written about individual anaphora, but less attention has been paid to…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

Large scale product and service reviews proliferate and are commonly found across the web. The ability to harvest, digest and analyze a large corpus of reviews from online websites is still however a difficult problem. This problem is referred to as "opinion mining." Opinion mining is an important area of research as advances in the…

Analysis of second language (L2) learners' language development can allow valid and reliable assessment of the learners' L2 linguistic knowledge, which can enable the teachers and researchers to choose appropriate teaching or experimental materials (Bardovi-Harlig & Bofman, 1989; Wolfe-Quintero et al., 1997). However, most language development…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

This dissertation explores how listeners extract meaning from personal and reflexive pronouns in spoken language. To be understood, words like her and herself must be linked to a prior element in the speech stream (or antecedent). This process draws on syntactic knowledge and verbal working memory processes. I present two original research studies…

Studies in English as a Foreign Language (EFL) indicate that the use of discourse markers (DMs) in the academic writing of second language learners improves the overall quality of these texts by contributing to their cohesion and comprehensibility (Saif Modhish 2012; Jalilifar 2008; Intaraprawat & Steffensen 1995). However, despite the…

This dissertation provides a comparative analysis of Complementizer Agreement (C-agr) in modern dialects of West Germanic from a diachronic perspective, attributing the rise and development of C-agr to the initiation and progression of a Linguistic Cycle specific to C-agr. Approached as a historical process of reanalysis and compensatory renewal…

This dissertation investigates the knowledge of English non-finite complement constructions by near-native L1 Spanish/L2 English learners. In particular, this study concerns Object Control, Raising to Object, and "for"-type constructions. Although the three constructions look identical on the surface, they are in fact distinct syntactic…

A growing number of studies has shown that collaborative writing tasks facilitate second language (L2) development by providing learners with opportunities to focus their attention on language and to collaborate in the solution of their language-related problems (e.g., Choi & Iwashita, 2016; Storch, 2013; Swain & Lapkin, 1998; Williams,…
