This dissertation investigates the development of cross-linguistic transfer in the use of strategies to repair preconsonantal word-external empty onsets (i.e., /C#V/) in Spanish heritage speakers. The main focus of this work is to analyze the use of /[glottal stop]/-epenthesis as a strategy to repair empty onsets, as its use is asymmetrical in the…

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…

This study explored the long-term academic impact of Two-Way Dual Language (TWDL) programs on both English-dominant and Spanish-dominant Hispanic students in a high-density Hispanic area. Specifically, it compared their academic performance in English Language Arts (ELA) and Math over a 3-year period to that of students enrolled in traditional…

Early childhood language experiences influence how a child's mind and brain process language and acquire literacy. For children growing up bilingual, their two languages interact in their minds, and these cross-linguistic influences can lead to unique neurocognitive mechanisms for language and reading compared to monolinguals. In this…

This study explores the experiences of second-generation Latine adolescents by examining the impact of bilingualism on self-esteem and depressive symptoms. Drawing on Suarez-Orozco and colleagues' (2018) model, this study shows the multifaceted acculturation process, emphasizing linguistic acculturation as crucial for navigating two cultures. The…

With the increasing prevalence of autism diagnoses globally, the overall aim of this dissertation is to improve our understanding of the linguistic aptitude of autistic individuals. Given that the autism diagnosis is a spectrum, we rely on the Autism Quotient (AQ) test, which measures the quantity of autistic-like traits an individual possesses,…

This dissertation centers on the study of Kaqchikel word associations and the social variation that exists within them. Theoretical and methodological considerations for this project stem from the fields of psycholinguistics, variationist sociolinguistics, and cognitive linguistics. Together, these form an approach that fits within a blossoming…

Bilingual children, the majority of whom are Spanish-English learners, now constitute over a third of the preschool population in the United States (Migration Policy Institute, 2021). Bilingual children and their families face multiple barriers to high-quality early childhood education, which are largely due to the underutilization of culturally…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

Even though engineering and science are tasked with developing solutions and knowledge for a diverse population, Black and Brown communities remain severely underrepresented in these disciplines. The problem exceeds easy solutions like "a seat at the table" and requires rethinking with whom and for whom the field designs ideas and…

Study 1: The present work examined the connection between language and conceptual development, investigating whether false-belief reasoning (FBR) and source-monitoring ability (SMA) abilities within the theory of mind (ToM) framework constrained the comprehension of semantic and pragmatic knowledge (evidential scalar implicatures) encoded in the…

As critical approaches to Heritage Language (HL) instruction are increasingly more widespread, it is now more pertinent than ever to conduct research on Spanish linguistic variation that reveals systematicity and refutes hegemonic notions of 'incorrectness'. This variationist study examines the use and distribution of the Preterite and Imperfect…

Traditionally, Basque has three voiceless affricates that are different in their place of articulation. More precisely, affricates can have a lamino-alveolar, apico-alveolar, and prepalatal place of articulation and the graphemes used to represent them are respectively. Likewise, Basque has been described as having three fricatives with the same…

This critical ethnography examines how the language ideologies of non-teaching staff (NTS) shape language practices in a bilingual PreK-8 school. Recent research on two-way bilingual education reveals the ways that the language ideologies of teachers, administrators, and parents can support the privileging of English in bilingual programs by…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…
