Ambiguity is a natural part of language and in studying the comprehension and resolution of ambiguity in a second language (L2), we must consider the influence of the native language. This dissertation examines L2 processing of the lexical semantic ambiguities, homonyms and polysemes. These are words that share the same form but have different…

This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

The partners of the Saudi students who come to the United States on scholarships to earn a degree (Bachelor's, Master's, or Ph.D.) are eligible for full scholarships as well. However, most of them fail to proceed in earning a degree or fulfill the language proficiency requirement needed to join an academic degree program. This study surveys…

This study examines the relationship between English Language Learners' (ELLs) English proficiency and standardized test performance. Utilizing a mixed-methods approach, it incorporates quantitative data from test scores and qualitative data from teacher surveys and interviews. Findings indicate a significant correlation between ELLs' proficiency…

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,…

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English-L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about…

Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

Foreign languages have been studied since the beginning of civilization; in the past few decades, there has been increased interest in understanding the role of motivation in learning a foreign language. Less than a quarter of studies on learning languages other than English (LOTE) have studied motivation. The purpose of this quantitative…

Teachers' beliefs about language and technology, pedagogy, and ability to integrate them can be challenging within the second language classroom. This study was a conceptual replication of previous work in the field of TPACK with world language teachers. This mixed-methods study included 59 current in-service world language teachers grades 9-12 in…

Attaining Advanced proficiency and beyond has been a principal goal for second language learners, practitioners, and researchers. Achieving this level in writing requires producing connected discourse of paragraph-level length and nurturing the ability to arrange various linguistic units to form a unified and cohesive whole. This ability, known as…

In this dissertation, I will present social-cognitive frameworks that support the use of mental imagery for possible self enhancement; and articulate and evaluate a pedagogical intervention designed for the foreign language class. This intervention will allow students to explore and develop prominent and vivid mental representations (self-schemas)…

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…

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 tantalizing prospects of learning benefits from multimodal conditions on second language (L2) learning in general, and L2 vocabulary development in particular, have important implications. Indeed, opening a language learning app on any device provides the immediate experience of simultaneous input modalities, and a wide range of input types.…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…
