Language learning is a complex issue of interest to linguists, computer scientists, and psychologists alike. While the different fields approach these questions at different levels of granularity, findings in one field profoundly affect how the others proceed. My dissertation examines the perceptual and linguistic generalizations regarding the…

Within second language acquisition research, L2 development has been traditionally analyzed through the dimensions of Complexity, Accuracy and Fluency (CAF) (Larsen-Freeman, 2009; Ortega, 2003; Skehan, 2009). Complexity within the CAF framework has gained the most attention and has often been examined through measures associated with clausal…

The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

The first part of this dissertation conducts a large-scale study comparing general and usage-based indices of syntactic complexity in L2 Mandarin writing samples across a wide range of proficiency levels. To do this, the Tool for the Automated Analysis of Syntactic Sophistication and Complexity (TAASSC; Kyle, 2016) was adapted for Mandarin by…

The purpose of this quasi-experimental, mixed-methods study was to address the gap in understanding regarding second language (L2) comprehension of stories by using a taxonomical approach based on Anderson and Krathwohl's (2001) revised taxonomy that includes multiple levels of cognitive processing to provide insight into L2 learners' depth of…

For Chinese students, studying in a country with different cultural components and language structures is challenging. Compared to English, the Chinese prefers shorter and simple sentence structure and allows for two sentences to be stated side by side. Different sentence structures in Chinese may influence native-Chinese readers' understanding of…

The present dissertation intends to investigate the syntactic nature and L2-acquisition of passive sentence structure in two Romance varieties, Italian and Spanish. First, I will present an analytic proposal couched within the Generative Approach (Chomsky, 1957, and subsequent work); from there, and following Perlmutter and Postal's (1977)…

Language learning is an important necessity of today's globalized society. Therefore, it is vital to provide the most effective methods for learning a foreign language. Through understanding how foreign language learning, cognitive load theory, learning modalities, and participants' physiological sex relate to one another, more effective…

In contexts of first language (L1) acquisition, prediction and adaptation are often viewed as fundamental to the learning process (Rabagliati et al., 2016). One mechanism that has been proposed to specifically account for such adaptive behavior is error-based implicit learning (e.g., Chang et al., 2006). According to this account, speakers…

The problem addressed in this study was that second language learners have difficulties pronouncing some English consonants that are not part of their language. Such errors occur because of first-language interference. The purpose of this qualitative case study was to explore the perceived effectiveness of using minimal pair training to…

The digital transformation in educational assessment has led to the proliferation of large-scale data, offering unprecedented opportunities to enhance language learning, and testing through machine learning (ML) techniques. Drawing on the extensive data generated by online English language assessments, this dissertation investigates the efficacy…

This study investigated the involvement of the Social Agency Theory within a multimedia learning environment to improve English language proficiency. The primary aim of this study is to find the effects of designing language learning instructional videos following the embodiment principle on language learners' motivation, cognitive load and…

The purpose of this evaluation was to investigate the factors that contribute to students' recruitment and retention in the Arabic program at my college. The two questions guiding this evaluation were: (1) what factors influence students to join the Arabic program at my college and (2) what factors influence students to continue to enroll in…

The focus of the current study was to explore and describe the shared experiences of international students as they adapted academically and socially to a Christian university in North Texas. The research focus resulted from the gap identified in the literature review: the lack of knowledge about the experiences of international students as they…
