The revised Speech Learning Model (SLM-r) postulates that learners with more precisely defined categories in their native language (L1) exhibit greater proficiency in acquiring sounds in a second language (L2). Despite its recent emergence, empirical studies validating this hypothesis remain scarce. This study aims to investigate the predictive…

This dissertation explores the experiences of East Asian international doctoral students in clinical supervision within counselor education programs in the United States. With the increasing enrollment of international students in these programs, understanding their unique challenges and strategies for success in supervision is essential. Using a…

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 goal of this study is to contribute to the field of Japanese pedagogy by examining how Japanese native speakers and learners of Japanese as a foreign language with American cultural backgrounds take stances in discussions in Japanese. As stancetaking is a fundamental human behavior (Du Bois & Karkkainen, 2012; Iwasaki, 2015; Kiesling,…

As the student population in today's world language classrooms becomes more diverse, the importance of interculturality has increased (NCES, 2022). Beyond this need for interculturality lies the development and teaching of critical intercultural competency (CIC) among world language students as a means of addressing systemic social injustices and…

In recent years, Third Language Acquisition (TLA) in Cross-Linguistic Influence (CLI) research has been debated regarding background languages' impact on learning a target language. While Second Language Acquisition (SLA) research often emphasizes the primary influence of the first language (L1) on the target language, it does not discount the…

Research into second language acquisition (SLA) has shown that individual difference (ID) variables can be strong predictors of language achievement (e.g., Dornyei, 2003; Skehan, 2003). Traditionally, this research conceptualized ID variables as static and monolithic variables (e.g., Dornyei, 2010). More recently scholars have questioned this…

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…

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…

In this dissertation, I explore the sociolinguistic perception of stylistic variation by native Spanish speakers and second language learners of Spanish. Within the field of Hispanic sociolinguistics and there is growing interest in studying the social information that listeners extract from language variation that speakers employ (e.g., Chappell,…

The current study explored individual differences in sensitivity to sub-phonemic variation of acoustic cues in the perception of a native language (L1) category in order to test the hypothesis that second language (L2) learners' different sensitivity to the L2-relevant acoustic dimension in L1 perception could explain individual variability in…

This research studied the impact of language barriers and cultural experiences on students' perceptions at the University of North Texas. The population of this study were students who had taken a class with a non-native speaking instructor and those who hadn't. Following a mixed-method research approach, online surveys were distributed to the…

Bilingual speakers present a natural phenomenon called code switch (CS) when communicating, where bilinguals or multilinguals alternate their languages during discourse. However, code-switching between two languages does not mean children cannot differentiate between the languages. Rather, code-switching is considered a common aspect of…

Cultural discontinuity is recognized as a culturally motivated academic process where sociocultural behaviors and communicative skills valued in the home culture of students are discontinued at school thus resulting in their low academic performance. This process may be reinforced by structural inequality in the mainstream society and education…
