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…

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…

The purpose of this research study was to investigate how minority First-Year Writing (FYW)/Composition faculty in the United States theorize and bring the notion of linguistic justice into their teaching. In other words, this study sought to examine pedagogies/practices minority faculty use to incorporate linguistic justice in their…

Registers are culturally recognized varieties of language that are associated with situations of use (Biber, Egbert, & Keller, 2020). Variation in frequencies of linguistic forms across registers is thought to be functional for the situations they are associated with; that is, certain language features are more common in one register than…

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"…

This dissertation examines whether and how psycholinguistic priming, and social knowledge are integrated in the identification of sociolinguistic variants. Using the English variable (ING), the alternation between -ing and -in' (e.g. thinking vs. thinkin') as a testing ground, this dissertation probes whether and how individuals utilize…

Some links between linguistic meanings and markers change systematically and cyclically in what are known as "grammaticalization paths." Although the empirical observations that give rise to these characterizations are cross-linguistically robust, the representations and cognitive processes that support these shifts are still not well…

It is standardly believed that some occurrences of expressions designate singularly, while other occurrences of expressions designate plurally. For instance, the singular expression the student may be used on an occasion to talk about one particular student, while the plural expression the students may be used on an occasion to talk about several…

A new generation is growing up who have known the internet for their entire lives. More people incorporate social media into more aspects of our lives, including how we learn and negotiate our identities. While formal online classrooms such as MOOCs are a part of the picture, learning also occurs in informal settings such as affinity groups'…

This research seeks to understand how secondary science students make space for themselves in the classroom. Specifically, this study examines the interplay between classroom structures and students' agentic negotiations while identifying the relationship between students' enacted agency and their authored science identities by drawing from a…

The tendency for negation to appear early in the sentence, dubbed the "Neg-First principle" by Horn (1989:452), has been observed in the domains of typology, language contact, and language acquisition. Based on evidence from these fields, scholars have speculated about the source and universality of Neg-First biases affecting language…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

The present dissertation discusses the importance of rootedness, defined as orientation towards place, and how it factors into sociolinguistic studies. Although rootedness is not a new concept in sociolinguistics, it has been infrequently operationalized to understand its role in language change. Linguists have discussed concepts similar to…

This dissertation explores the effects of frequency on the learning and use of linguistic constructions. The work examines the influence of frequency on form choice in production and meaning inference in comprehension and discusses the effect of each modality on diachronic patterns of change in language. In production, high frequency of a form…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…
