Pidgins, narrowly defined, are auxiliary languages reserved for communication with linguistic outgroups. Although implicitly recognized as a class of languages by many linguists, there has been little systematic typological investigation of pidgins. This dissertation presents the first large-scale typological study of morphology and functional…

Research in first-language (L1) sentence processing has found evidence that language comprehenders use binding condition A as a filter to rule out noun phrases that are binding-inaccessible before proceeding with the task of finding the correct antecedent. Sturt (2013) notes that this strategy does not appear to apply to advanced speakers of…

Learner corpus research has expanded from focusing primarily on English as a second language (L2) to include languages such as L2 Spanish, reflecting the growing importance of corpus linguistics in second language acquisition (SLA) research. In this context, and because prompts are the means by which learner corpora gather their texts, it has…

In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

The Null Subject Parameter (NSP) has long been considered pertinent to Second Language Acquisition (SLA) studies, especially when the native language (NL) and target language (TL) have different NSP settings. The study aimed to investigate whether seventy English L2 learners in Puerto Rico who were native Spanish speakers transferred their L1…

Research over the past two decades has reported a robust relationship between relative social status and first-person singular (FPS) pronoun use in English. For my dissertation study, I wanted to test the replicability of those findings using American Sign Language (ASL) data that I collected for this purpose. In alignment with previous work, I…

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…

The current dissertation investigates factors that influence usages of Japanese honorifics and explores how instructors can introduce honorifics more effectively to second-language learners. Apart from existing literature, my data includes a corpus of real-life usages of Modern Japanese, classroom observations, interviews with Japanese language…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

There has been increasing L3 research on L3 transfer selectivity, especially concerning which factor triggers crosslinguistic influence during L3 acquisition. According to Slabakova's (2016) Scalpel Model, every linguistic property has distinct and unique input factors regarding L3 acquisition such as high/low frequency or positive/negative input.…

Language forecasting, i.e., predicting the future state of a language, has long been regarded with a fair amount of skepticism. This is partly due to language change often being considered sudden, random, unpredictable, and viewed as the result of complex interacting factors that are not well understood (e.g., Keller 1994:72; Bauer 1994:25; Labov…

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…

The relationship between language and thought has fascinated us for centuries. The relationship between the two is far beyond what the two words represent on the literal level, and the discussions around it have been covered in various fields from philosophy and psychology to linguistics. Even complicating the situation, the relationship between…

Since corpus linguistics gained popularity as a methodology in the latter half of the 20th century, second language acquisition research has seen the emergence of work investigating formulaic language, such as idioms, lexical bundles, and collocations. A collocation is a string of words that co-occur more routinely than probability would predict,…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…
