Students bring cultural and linguistic richness to the English Language Arts classroom in the form of English language diversity; that being said, English Language Arts (ELA) education has traditionally privileged Standard American English (*SAE) and its related white culture rather than embrace the aforementioned diversity. With calls for more…

This dissertation examines native speakers' word recognition of, differentiation between, and social attitudes toward varieties of Arabic. It is a particularly interesting test case because of the Arabic unique regional variation situation and the available literature lacks data on how Arabic speakers perceive different accents, with a particular…

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…

There is a growing body of research from various perspectives in heritage language (henceforth HL) acquisition as an emerging field. Some studies proposed that HL acquisition is a differential acquisition compared with the baseline language (i.e., the language spoken by the parents or caregivers) (Kupisch & Rothman, 2018; Dubiel &…

Speech is highly variable and systematic, governed by the internal linguistic system and socio-indexical factors. The systematic relationship of socio-indexical factors and variable phonetic forms, referred to here as "socio-indexical structure," has been the cornerstone of sociophonetic research over the last several decades. Research…

A listener's explicit knowledge of the links between phonetic variants and social categories can be referred to as their sociophonetic knowledge. The goal of this dissertation was to directly examine the degree to which sociophonetic knowledge influences listeners' ability to process and encode lexical tokens produced in different accents, with…

Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

International schools, which are often rich with linguistic diversity, typically promote that proficiency in an accepted standard variety of English is the desired and favored outcome for students (Hayden & Thompson, 2016; Spiers, 2016). These schools, in part due to the teachers they employ, could be characterized as systems that promote…

This dissertation investigates the pathways and causes of the development of glide deletion in Seoul Korean. Seoul provides fertile ground for studies of linguistic innovation in an urban setting since it has seen rapid historical, social and demographic changes in the twentieth century. The phenomenon under investigation is the variable deletion…

During conversation, talkers may adapt their speech in a variety of ways. One form of speech adaptation is clear speech, in which a talker selectively hyperarticulates segments when faced with specific communication challenges. The present speech production experiment investigated how talkers adapt a common feature of American English dialects:…

In this dissertation project, I examine how professionals in the South use their Southern United States English (SUSE) to communicate in business situations. My goals are to (1) understand how regional language variety rhetorically shapes written professional communication and (2) establish a pedagogical framework for business writing that attunes…

Given the increasing number of multilingual learners enrolled in U.S. secondary schools and persistent disparities in access to quality STEM education for these students, teacher education programs must prepare secondary science teachers capable of teaching multilingual learners in equitable ways. There is a consensus in science education…

Scholars have long debated whether Old and Middle English (ME) are different diachronic stages of one language, or whether they are two closely related languages that have different historical roots. A general assumption is that Middle and Modern English descend from Old English (OE), similar to the way Middle and Modern German descend from Old…

The traditional Philadelphia allophonic /ae/ system (henceforth: PHL shown in (1) below) is characterized by a set of complicated conditioning factors and a dramatic acoustic distinction between the two allophones. In recent years, some Philadelphians have begun to exhibit a new allophonic system (NAS, shown in (2) below). Like PHL, NAS is…

This dissertation explores dialect diversification in the long-distance New World Plautdietsch speech community. Plautdietsch dialects are traditionally classified as belonging to one of two types: either Chortitza or Molotschna. The traditional dialect classification has recently come under scrutiny because speakers rarely use features exclusive…
