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,…

The current study explores variation in phonemic representation among Spanish--English dual language learners (DLLs, n = 60) who were dominant in English or in Spanish. Children were given a phonetic discrimination task with speech sounds that: 1) occur in English and Spanish, 2) are exclusive to English, and 3) are exclusive to Russian, during…

This study examines cross-linguistic influence (CLI) in the acquisition of embedded "wh"-questions in L3 English in German-dominant heritage speakers (HSs) of Italian. Specifically, we investigate whether a higher proficiency in the heritage language Italian increases the potential for CLI from that language. To this end, 21 adult-aged…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

The current work investigates whether language dominance predicts transfer of skills across cognitive-linguistic levels from the native language (Spanish) to the second language (English) in bilingual preschoolers. Sensitivity to cognates ("elephant/elefante" in English/Spanish) and metalinguistic awareness (MLA) have both been shown to…

This paper provides a qualitative account of Vietnamese language maintenance in Manchester. Through ethnographic observations of distinctly Vietnamese locations, Vietnamese language practices are shown to create spaces in which Vietnamese is the dominant language, and in which Vietnamese norms and expectations, or scales, are able to influence and…

Measuring language dominance, broadly defined as the relative strength of each of a bilingual's two languages, remains a crucial methodological issue in bilingualism research. While various methods have been proposed, the Bilingual Language Profile (BLP) has been one of the most widely used tools for measuring language dominance. While previous…

This coda considers how translanguaging discourse is manifested in classrooms. Li Wei and Lin open up spaces of possibility for translanguaging by questioning the order of language. In so doing, the school code assumes its appropriate place as a system of coloniality.

Three gaps seem to be present within the literature of peace education: relatively little self-critique of the internal workings of the field; a dearth of studies featuring the personal narratives of peace educators; and an underrepresentation of peace educators from the Global South. To address these three gaps, this qualitative investigation…

Quantifier-Negation sentences allow an inverse scope reading in Tibetan but not in Chinese. This difference can be attributed to the underlying syntactic difference: the negation word can be raised at Logical Form in Tibetan but not in Chinese. This study investigated whether Chinese-dominant Tibetan heritage speakers know such difference. We…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

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…

This book sheds light on the role of mother tongue-based multilingual education (MTB MLE) as a means to enhance educational outcomes, creating a space for non-dominant languages alongside more dominant regional, national and international languages. It brings together a number of underlying concerns including the maintenance of non-dominant…

We longitudinally examined the trajectories of Latine mothers' (N = 116) language input to their children during book-sharing interactions at four points in development, when children were between ages 2 and 5 years. Mother-child dyads were video-recorded sharing a wordless picture book, and transcriptions of mothers' and children's language…

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…
