ABSTRACTIn the context of English as a foreign language (EFL) education at Saudi universities, intrinsic motivation plays a crucial role in the second language (L2) learning process. Drawing on the theoretical framework of Self-Determination Theory (SDT), this thesis investigates how learner autonomy can be enhanced to promote intrinsic motivation among Saudi EFL learners. This thesis offers a literature review to explore the significance and application of intrinsic motivation proposed by the identified empirical studies in this context. It begins by providing a general overview of motivation and the relationship between learner autonomy and intrinsic motivation based on SDT. After that, it explores the identified studies in this context by providing an in-depth analysis of each study. To comprehensively review the existing literature, a methodical search strategy was employed. The Arizona State University Library and the Education Resources Information Center (ERIC) were utilized. The focus was on empirical studies that emphasized intrinsic motivation in the context of EFL students in Saudi Arabian universities and how to promote it, with particular attention to the principles of SDT regarding learner autonomy. It further suggests that enhancing autonomy, as viewed through the lens of SDT, could provide the necessary conditions for intrinsic motivation to thrive in the context of EFL in Saudi Arabia. A justification for this review was the evident gap in the literature as there are only five identified studies that met the criteria of selection in this context. This thesis contends that integrating SDT's view of learner autonomy with a balanced approach to structured and choice-based learning may effectively bridge the gap identified in the current research on intrinsic motivation. Although the studies at hand present a valuable addition to intrinsic motivation within the EFL context in Saudi universities, they fall short in some respects. ii Therefore, this thesis advocates for an educational model that applies SDT-based autonomous learning strategies into the curriculum to enrich the intrinsic motivation of Saudi EFL students. Several recommendations regarding how to promote intrinsic motivation are presented.

Social scientific scholarship has emphasized how parents’ undocumented legal status might influence the emotional, social, and economic well-being of mixed immigration status families, pointing to a greater need to better understand the lived realities of the undocumented population. Although Arizona is home to a large and growing number of undocumented migrants, a strongly anti-immigrant socio-political environment shapes the experiences and opportunities that migrants encounter. With an estimated 16 million people living in mixed-status families nationwide and over five million children under 18 living with at least one undocumented parent, deportability is an urgent social problem. This qualitative dissertation draws on narrative and discursive methods to shed light on the spatiotemporal dimensions of undocumented migrant mothers’ narratives, with a particular focus on the understudied area of how identities are constructed, performed and/or resisted in narratives of the future. Narrative inquiry is a useful method to explore issues of identity construction and negotiation in migration contexts. Theoretically, my approach leans on identity as a discursive practice, as contextualized and negotiated in storytelling. The study is further guided by a dialogic/performative approach to narrative. Analytic concepts, such as (im)mobility and imagination, and Bakhtinian theory of novelness, particularly dialogism and chronotope, also inform my approach to narrative analysis. Data come from sixteen hours of semi-structured interviews with seven undocumented mothers from Mexico who live in mixed-status families in Arizona. The findings show that the participants oftentimes felt at the bottom of the local social hierarchy due to their undocumented legal status. Furthermore, findings shed light on how the participants perceived, imagined, negotiated and sometimes resisted various social and spatial (im)mobilities in contexts of illness, loss, and grieving. The analysis also demonstrates how the participants navigate their spatiotemporal fragility through discourses of imagination and contrastive chronotopes as they raise their children and consider alternative timespaces for their future.

This dissertation study investigated how L2 doctoral students regulate their emotions upon receiving written feedback from their mentors. The study took a multiple-case-study approach that entailed stimulated recall of the feedback-reading and revision process. Three international doctoral students who were engaged in high-stakes writing in the third and fourth years of their doctoral program participated in the study. The data from the stimulated-recall and interview talks were analyzed and coded for emotion-regulation strategies and how they were used in the participants’ revision process. The results show that the participants, while processing feedback, experienced a variety of emotions—both positive and negative—that stemmed from the challenges of working in an academic setting, life as a scholar, and social relationships. They also regulated their emotional reactions by suppressing immediate emotional responses or by reappraising their thoughts to proactively reduce the emotional impact. The results also show that one of the key functions of emotion regulations in the writing process may be to prevent writer’s block. These findings, unlike previous studies, provide an understanding of how individual variations of emotion regulation strategies are exercised and how regulation impacts the process of writing in a naturalistic context. In addition, the findings suggest the need for future studies to identify the necessity and efficiency of emotion regulation strategies within the L2 writing context and establish an inventory of emotion regulation strategies that allow researchers, teachers, and writers to recognize ways to sustain an effective writing process.

Temporal features and frequency of pauses have been studied extensively in the literature, but the interest in the syntactic location of pauses is a more recent development. While previous research has studied the pause patterns of L1 and L2 speakers as well as the effects of pause location on perceptions of fluency, these studies have all utilized a binary approach the categorization of pauses as occurring either between or within clauses or major constituent boundaries. This research attempts to take a look at pause placement with a finer distinction of pause location, including junctures that occur between and within phrases. To accomplish this, two experiments were conducted. The first experiment gathered read-aloud speech samples from native, non-native, and heritage speakers of Mandarin Chinese, which were then manipulated in Praat to contain only a single pause that occurred either between or within phrases. The samples were presented to native Chinese speakers to assess for perceptions of fluency as affected by the pause location condition. Findings of this preliminary pilot study did not find a significant correlation between pause location and perceptions of fluency at the phrasal level. The second experiment gathered spontaneous speech samples from the same speaker population as Experiment 1. The pauses that occurred in the samples were coded according to a system developed by the author to account for eight different syntactic junctions, and the percentage of pause at each location was calculated. Analysis showed a significant correlation with pause location and percentage of pauses (p < 0.01), as well as a statistically significant interaction between the effects of speaker status and pause location on percentage of pause (p = 0.011). The findings of this study are limited due to the small population size, but research in this fine-grained analysis of pause location within a clause has implications in the fields of L2 acquisition, psycholinguistics, and natural language processing.
