Social information is cognitively linked to linguistic information, evidenced by bidirectional influences on perceptual processing of speech. Models of sociophonetic cognition theorize that the way linguistic experiences are interpreted and stored in memory is mediated by listener attention, which is guided by ideology. This relationship, however,…

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…

The purpose of this dissertation is to examine the perception of unstressed vowel reduction (UVR)--also known as vowel devoicing--in Central Mexican Spanish. UVR is a variable, gradient process in which vowels undergo a constellation of phonetic weakening processes including shortening, devoicing, and apparent deletion (Gordon 1998). While it is…

There is a long-standing gap in literacy achievement between African American and European American students (e.g., NAEP, 2019, 2022). A large body of research has examined different factors that continue to reinforce performance differences across students. One variable that has been a long-term interest to sociolinguists and applied scientists…

Perception of second language (L2) speakers and their speech is known to be influenced both by phonetic and by sociolinguistic factors. The existing body of scholarly research on L2 speech perception, however, is overwhelmingly focused on Indo-European languages, raising doubts about the generalizability of existing sociolinguistic, phonetic,…

Sociolinguistic variation (SLV) entails that language is affected by social context (i.e. register, pragmatics). Interest in the acquisition of sociolinguistic variation in a second language (L2-SLV), as a key component of communicative competence, has grown exponentially over the past thirty years (Geeslin & Long, 2014). Researchers have…

This research investigated how a Critical Sociocultural Linguistics Literacy (CriSoLL) approach to authentic materials supports student literacy in a mixed Spanish heritage language (SHL) and additional language (L2) Spanish intermediate course at the university level. Using a qualitative approach (Cho, 2018; Esposito & Evans-Winters, 2021)…

While much of the existing literature on code-switching focuses on languages that differ typologically, this dissertation focuses on typologically similar languages. Code-switching between Mandarin and Taiwanese is examined through the perspectives of 1) sociolinguistics, 2) typology, 3) phonetic and phonological production, and 4) speech…

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 investigates how feminist and LGBTQ undergraduate students involved in activism on UC Davis use language to construct their identities, focusing on two gender and sexuality-based resource centers (the women's center and LGBTQ center). It seeks to address two research questions. First, how do cisgender, trans, and nonbinary…

Resulting from France's centuries-long colonial project across several continents, French is estimated to be the fifth most widely spoken language globally. Yet, despite its presence across continents and despite the linguistic diversity within France itself, notions of 'good' and 'correct' French continue to be associated with the image of the…

Teacher diversity is essential for creating inclusive learning environments, as teachers who reflect their students' backgrounds can better serve their needs and positively impact learning outcomes. As the Sweet Home CSD classrooms become increasingly diverse, the homogenous teaching force has failed to keep pace, with more than ninety-six (96%)…

The Science of Reading era has (re)ignited conversations about equitable literacy instruction. Conflicting literacy research and literacy media reports complicate matters further. Guided reading, a ubiquitous form of small group instruction designed to meet readers' needs through individualized conferring and independent reading with…

World language study exposes students to more than just language; they are also exposed to different cultures. After graduating, students will be exposed to different languages and cultures in the workforce, and they must be prepared. Students often leave their language of choice after the one or two semester course requirement; it takes more than…

*English Learners in secondary school settings often face discrepancies in opportunities and outcomes. Methods to address these discrepancies are grounded in an instrumental approach to instruction, wherein educational practitioners are understood to require methodological intervention in the form of professional development by a more experienced…
