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?…

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…

Counterfactuals are a type of conditional sentences used to convey situations that do not correspond to reality. Tense morphology is a core ingredient to encode counterfactuals in English and most Indo-European languages. Mandarin Chinese (hereafter Chinese) lacks tense morphology and does not require counterfactuals to be formally distinguished…

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…

The founding and inception of Coral Way's bilingual program marked the beginning of Miami's multilingual era, as well as the start of modern bilingual education in the U.S. As multilingual and multicultural Miami has evolved, bilingual programming has not remained a priority in the school district. This dissertation study examines how language…

Within the past few decades, notable contributions have been made in heritage language education research that continued to gain ground in language pedagogy and teaching practices (e.g., Davila, 2017; Valdes, 2000; Fishman, 2001; Kelleher, 2010; Polinsky & Kagan 2007). This dissertation is guided by translanguaging and social identity, two…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

Research over the past two decades has reported a robust relationship between relative social status and first-person singular (FPS) pronoun use in English. For my dissertation study, I wanted to test the replicability of those findings using American Sign Language (ASL) data that I collected for this purpose. In alignment with previous work, I…

The tendency for negation to appear early in the sentence, dubbed the "Neg-First principle" by Horn (1989:452), has been observed in the domains of typology, language contact, and language acquisition. Based on evidence from these fields, scholars have speculated about the source and universality of Neg-First biases affecting language…

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)…

The current dissertation investigates factors that influence usages of Japanese honorifics and explores how instructors can introduce honorifics more effectively to second-language learners.

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…

Language teachers in China often use picturebooks as complimentary teaching materials to standard textbooks for language instruction. However, research shows that current applications of picturebooks in Chinese English as a foreign language (EFL) classrooms mainly focus on helping students develop linguistic competence, with little attention on…
