This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

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…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Learner corpus research has expanded from focusing primarily on English as a second language (L2) to include languages such as L2 Spanish, reflecting the growing importance of corpus linguistics in second language acquisition (SLA) research. In this context, and because prompts are the means by which learner corpora gather their texts, it has…

Research on language and cognitive processes in bilinguals over the past few decades has underscored the activation of words in the first language (L1) during comprehension and production of the second language (L2) (e.g., Dijkstra, Van Jaarsveld, & Ten Brinke, 1998; Van Heuven, Dijkstra, & Grainger, 1998; Hermans, Bongaerts, De Bot, &…

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 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…

This research investigated how a Critical Sociocultural Linguistics Literacy (CriSoLL) approach to authentic materials supports student literacy in a mixed Spanish heritage language (SHL) and additional language (L2) Spanish intermediate course at the university level. Using a qualitative approach (Cho, 2018; Esposito & Evans-Winters, 2021)…

This qualitative multi-case study examined the co-construction of elementary dual language students' language use and identity to understand how five individual students positioned themselves as bilingual individuals as well as how this relates to their investment in the language-learning process. This study also investigated the influence of…

This dissertation investigates how bilinguals use their two grammars to comprehend written intra-sentential codeswitches. I focus on adjective/noun constructions in Spanish and English where I manipulate the congruence of grammatical word order in the two languages across the codeswitch boundary. This allows me to test three codeswitching…

Accurately identifying developmental language disorder (DLD) in students who speak a home language other than English has proven to be an enduring challenge. Consequently, students with DLD miss out on critical interventions, and those who are acquiring their two languages in a typical manner are placed in settings that do not meet their…

Discourse markers (DMs) are linguistic forms characterized by their use as conversation organizers or pause fillers (Fox Tree, 2010). Although used frequently in both speech and writing, DMs are not often taught in L2 classrooms, despite incorrect usage causing potential misunderstandings (Polat, 2011). Additionally, L2 learners have been observed…

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…

The Los Angeles Unified School District has undertaken an experiment in the education of immigrant students learning English. 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…

This mixed-methods explanatory sequential study aimed to identify the most commonly used World Language curriculum models in New Jersey high schools, assess the level of curriculum coherence in Spanish programs, and examine their impact on student learning. Surveys and interviews with high school Spanish teachers revealed that, while theoretical…
