There is a significant diaspora of Mixtec people residing along California's Central Coast, mostly working in the agricultural sector. The new realities in the diaspora have brought Mixtec varieties in contact in new contexts where they co-exist with other Mexican Indigenous languages, as well as with Spanish and English. We urgently need more…

Increasingly, speakers of minoritized languages around the world are becoming uprooted due to economic pressures, political forces, and environmental destabilization. As communities leave their traditional homelands, they often experience accelerated language shift. Although youth are in a critical position to further transmit their languages to…

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…

In the face of colonial efforts to extinguish Indigenous language and culture, Kanien'keha:ka (Mohawk people) have been working to revitalize Kanien'keha (the Mohawk language) since the 1970s. However, Kanien'keha continues to experience greater speaker loss than gain. Through a comprehensive vitality assessment, this dissertation examines the…

This dissertation examines individual, constricted agency in a multilingual environment within the context of a language discussion group and the form of social capital possessed by their Mexican Indigenous diasporic community living on the California Central Coast. The research is based on participant-observation ethnographic work with a language…

Quechua language education and research has long been relegated to rural areas and elementary schools of the Andes. Nonetheless, current language policy in the southern Peruvian region of Cusco has opened new opportunities for Quechua, a minoritized Indigenous language, to be taught in cities and towns and in high schools. In this sociolinguistic…

Nawat, the highly endangered indigenous language of El Salvador, is undergoing a revitalization process. This dissertation, conceived within this context, focuses on the second-language (L2) acquisition of features of Nawat pronunciation by learners who have Salvadoran Spanish as their first language (L1). Specifically, I assess the acquisition of…

This research is a study of the relationship between language acquisition and the status of equity. The history of the Maya people in Guatemala gives strong evidence that their failure to acquire competence in Spanish, which is the national language of their nation, has resulted in their failure to compete in the social, economic, and political…

Do assimilationist restrictions on a minority language lead to greater national unity or a more rebellious minority population? Under what conditions might short-term backlash to language assimilation evolve into greater national unity in the long term? While much of the literature on ethnic politics implicitly treats language simply as an…

The promotion of language ideologies, policies and pedagogies that treat languages as separate and hierarchical has become a central concern for critical education scholars. In this case study, I explore how school actors at Colegio Colombiano (CC), an international school in Colombia, engaged with critical approaches to bi/multilingual education…

Over the 2021-2023 school years, the district opened three new high school Academies for recently-immigrated students explicitly tasked with centering their home languages to support their success in school. The students…

In response to widespread language loss, many Native American communities are engaged in revitalizing their languages. This dissertation is a systematic account of a tribal member learning Mutsun in the context of a language reclamation project. The last fluent speaker of Mutsun, a Costanoan language of central California, died in 1930. This study…

Linguistic ideologies are informed by social stereotyping to maintain the "standard" variety which is often interpreted as morally superior to "nonstandard" varieties. Consequently, these ideologies racialize "nonstandard" varieties, leading to even more negative stereotypes. One outlet of such stereotypes can be…

Child speech is highly variable. The speech apparatus--the vocal tract, tongue, teeth, and vocal folds--develop at different rates for different children, which helps explain some of the variability in children's speech. For example, the ratio of the oral to pharyngeal cavities changes as children age, making it difficult to establish reliable…

How are linguistic and cognitive practices shared among individuals (and more broadly) populations and cultures? Further, how are cognitive strategies shared at the local level? Li and colleagues (Li & Gleitman 2002; Li et al 2011; "inter alia") suggest that the variation observed in reference frame practices among populations of the…
