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?…

Previous studies on second language (L2) phonetic acquisition in early bilingual learners have mainly examined immigrants to the L2 country; however, with recent growing dual-language immersion programs, the immersed bilingual group emerged and required more attention in the research. This study aims to investigate vowel patterns of young…

The dissertation focuses on the Chinese literacy experiences of different generations of Thai Chinese families in Thailand, spanning periods characterized by varying ideologies toward the Chinese language, which have either constrained or facilitated its acquisition. This qualitative work examines how evolving national policies and international…

Relative clause (RC) production is an important language milestone for children. Incorporating a felicitous context when assessing RC production is of theoretical and clinical value. This study investigated how a felicitous context influenced elicited production of RCs from monolingual English-speaking and bilingual Mandarin-English speaking…

This dissertation investigated how four factors -- the degree of L2 experience, L1 sound structure, age difference in L1 language development and age of L2 exposure -- affect the perceptual cue weighting of duration and spectral differences for English tense-lax vowel contrasts. Four major hypotheses were tested: desensitization hypothesis (DH)…

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…

The processing of structurally ambiguous sentences has proven resourceful in understanding the human parser. In particular, the resolution of globally and temporarily ambiguous relative clauses (RC) preceded by a complex noun phrase (NP) such as "Someone shot [the servant]NP1 of [the actress]NP2 [who was on the balcony]RC" has been found…

Adult second-language learners are a growing population of students in many countries throughout the world as the global community continues to expand beyond not only physical borders, but cultural and language borders as well. 200 expatriates, who lived in Denmark during the time span of 2006-2016, who were required to show proficiency in their…

"Generation Z" multilingual writers are caught up in a globalized/globalizing and superdiverse linguistic and cultural contact zone as well as a neoliberal political and institutional environment. To understand how they inhabit their idiosyncratic literate worlds and practice their differences, I aligned myself with an ethnographic case…

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…

This dissertation explores Spanish copular verbs, "ser" and "estar" (both 'to be' in English), in pre-adjectival contexts within two Spanish varieties: first-language (L1) Chilean speakers from Santiago (N = 29) and second-language (L2) English-speaking learners studying in Chile (N = 31). Bridging sociolinguistics and second…

The present dissertation analyzed speech production and perception in early heritage Spanish-English bilingual children. Specifically, I investigated how perception and production of lexical stress develops in bilingual children. Current models of second language (L2) speech perception do not include heritage bilinguals or suprasegmental aspects…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

As grit has been associated with elements of academic success throughout the literature, it was of interest to the current study to analyze grit within the context of online, international ESL students enrolled in an American university. Thus, this study examined the predictive properties of grit (using both Spearman rho and stepwise regression…

Through this descriptive qualitative case study of three native speaking Arabic teachers in an L2 Arabic classroom in a private school setting in the U.S., this study presented a four-stage multi-layered analytical approach demonstrating functional, interactional and pedagogical analyses of the uses of Arabic Arabic pragmatic markers (PMs) in…
