People segment their continuous stream of experience into events, or temporal segments that have a beginning and an endpoint. But how are such event boundaries defined? Linguistic theories of event encoding draw a distinction between bounded events that are non-homogeneous, structured temporal developments leading to an inherent endpoint (e.g.,…

Successful language comprehension requires the rapid deployment of working memory resources alongside the capacity to predict upcoming linguistic input. While previous research views these as competing factors, this dissertation explores a unified theory of processing complexity and evaluates the interaction between memory and prediction. The…

The Q-diffusion model is a cognitive process model that considers decision making as an unobservable information accumulation process. Both item and person parameters decide the trace line of the cognitive process, which further decides observed response and response time. Because the likelihood function for the Q-diffusion model is intractable,…

Scalar inference, the process by which we infer meanings stronger than what was explicitly said, has long been a central topic of investigation in theoretical semantics-pragmatics, as well as in psycholinguistics. Upon encountering the sentence "Mary ate some of the deep dish", for instance, hearers regularly compute the pragmatic…

Interruptions are already ubiquitous throughout society, and the attention-driven economy may be training us to constantly switch tasks and refocus our attention without ever lingering on one activity. Previous studies of interruptions during work have found many negative outcomes (e.g., more errors, higher workload, slower task time) and some…

The purpose of this single phenomenological case study was to examine the importance of an FYE or College 101 seminar and why this topic matters to Latinx students' success. The research took place in a two-year Hispanic Serving Institution (HSI) located in the Southwest part of the United States. The overarching question was: "How can…

This dissertation investigates the problem of how variations in the intensity of three selected constructs--multimedia signaling, speed and pacing, and cognitive engagement prompts--affect attention and learning outcomes in online learning environments. The study explores the intersecting cognitive theories of cognitive load, higher order thinking…

This study quantitatively and qualitatively measured gender and age differences in cognitive, affective, and behavioral engagement while playing video games among the University of North Texas (UNT) undergraduate students. Also, it examined the relationship between time spent playing video games and the three engagement states. For the…

Latinx working adults without bachelor's degrees face significant barriers to economic stability and upward mobility, thereby reducing generational wealth. There are significant benefits of degree completion to individuals, such as increased earnings and employment, and benefits to society through greater economic contribution, increased…

When individuals read a narrative text, they construct a mental representation known as a situational model to comprehend the unfolding story. These models require updates at meaningful changes in the story to reflect current information accurately. Existing research highlights the attentional and working memory demands of these updating…

The effects of fluency-based instruction and accuracy-based instruction on contingency adduction were assessed using an alternating treatments design. Stimulus equivalence tasks were used to measure contingency adduction. Stimulus classes were composed of arbitrary visual forms. One treatment condition consisted of teaching fast, fluent responding…

This study examined online graduate students' perceived learning styles and perceptions of factors that influenced their overall academic achievement in online courses. The study explored relationships between the learning styles and the factors identified as influencing achievement. Previous research produced mixed results when evaluating the…

This dissertation examines the experiences of people with disabilities in academia. It is oriented autoethnographically by my own experiences, and those of other students and faculty, to make vivid the phenomenological realities of living on crip time, navigating independence, the cognitive load of disability, and disclosure management. I argue…

This qualitative, non-experimental meta-synthesis explored the antecedents, consequences, and interventions of both active and passive procrastination among university students. Based on the academic procrastination paradigm proposed by Schraw, Wadkins, and Olafson in 2007, the study synthesized and interpreted the findings of twelve purposefully…

In 2021, the U.S. Surgeon General declared a children's mental health crisis, and the Centers for Disease Control and Prevention (CDC) reported an increase in the prevalence of youth mental health needs stating that adolescents are in crisis (Reinert et al., 2021). Since 2021, a significant amount of literature has been published, indicating that,…
