A Heart So White: Musical Reflections On Lady Macbeth's Mind, Caitlyn N. Long

Undergraduate Theses

A Heart So White: Musical Reflections on Lady Macbeth’s Mind reimagines one of Shakespeare’s most infamous characters through a trauma-informed lens. This thesis combines artistic creation with interdisciplinary research in psychology, dramaturgy, and musical theatre studies to explore Lady Macbeth’s psychological unraveling and reclaim her from centuries of villainization. Composing from Lady Macbeth’s perspective allowed for a deeper exploration of her guilt, dissociation, repression, and isolation—symptoms traditionally overlooked in favor of Macbeth’s more visible descent into violence. Through musical motifs, lyrical reinterpretation, and staging concepts, the work seeks to humanize Lady Macbeth and highlight how trauma shapes behavior, relationships, and …

Interrelationships Among Social Media Use, University Social Capital, And Mental Health Outcomes In Undergraduate Students, Md Hasan Howlader

Lingnan Theses (MPhil & PhD)

Mental health concerns among university students have intensified globally, reflected in rising levels of psychological distress, declining life satisfaction, and reduced flourishing. These challenges present urgent implications for public health and higher education policy. Simultaneously, social media use (SMU) has become deeply embedded in students’ daily lives; however, its impact on mental health remains inconclusive. While some studies associate SMU with increased mental health issues, others emphasize its potential to foster social connection. These conflicting perspectives are further complicated by uncertainty regarding the directionality of these relationships—whether SMU influences mental health, or mental health status shapes SMU patterns. Furthermore, existing …

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh

University Honors Theses

Within Christian theology, forgiveness is a foundational concept that is often understood as a divine command, a spiritual practice, and a path toward reconciliation and personal growth. Recent neuroscientific research further supports this viewpoint, providing data that shows forgiveness engages neural systems responsible for emotional regulation, empathy, moral reasoning, and perspective-taking. Through neuroplasticity, repeated acts of forgiveness reshape the brain, strengthen connections between prefrontal and limbic regions, reduce amygdala reactivity, and enhance emotional stability and cognitive flexibility. Although forgiveness offers many benefits, modern culture frequently distorts its meaning, framing it as a sign of weakness, gullibility, or a form of …

Leadership and Strategy Faculty Publications

Understanding generational differences in engagement with Management Trainee (MT) programs is crucial for talent development, yet comparative studies linking these experiences to employee retention are limited. This study addressed this gap by investigating the distinct motivations and retention drivers of Filipino Gen Z and Millennial graduates from the MT program. Using a qualitative research design, in-depth interviews were conducted with six professionals (three Gen Z and three Millennials) who completed structured MT programs in Philippine-based organizations. The data were analyzed using a comparative thematic analysis framework adapted from Braun and Clark. Findings revealed key distinctions in motivations and retention drivers. …

Structural Equation Modeling Of Educational Factors Associated With Racial Trauma: Belonging, Efficacy, And Persistence Among Bipoc College Students, Miguel Castano, Richard Chang

Undergraduate Research Symposium Posters

Racial trauma refers to post-traumatic stress disorder symptoms from repeated exposure to racism and racial discrimination, generally expressed as hypervigilance and lack of safety, negative cognitions causing bleak perceptions of oneself and the world, and difficulty coping through reduced ability to manage distress. Literature shows that BIPOC students encounter racism on university campuses more frequently than non-BIPOC students, suggesting they are more vulnerable to racial trauma. Racial trauma has been linked to negative mental health outcomes; however, little is known about its impact on educational outcomes. Academic belonging, self-efficacy, and persistence are key educational factors tied to academic performance and …

School Shooting Drills Across Grade Levels: What We Know And Don't Know About Student And Teacher Experiences, Katherine Cutié

Undergraduate Research Symposium Posters

School shooting drills have become a standard component of school safety procedures in U.S. K–12 education, yet their psychological effects remain under-researched. This literature review synthesizes findings from 39 studies published between 1999 and 2025 to describe patterns in how students and teachers experience these drills across grade levels and drill types. Across the literature, anxiety and fear were the most frequently examined student outcomes, while teachers commonly reported stress, concerns about developmental appropriateness, and increased emotional labor during drills. Lockdown procedures were most frequently examined in the reviewed studies, with less research addressing ALICE, Run–Hide–Fight, and simulation drills. Few …

Exploring The Stability Of Misophonia And Other Auditory Affective Experiences Throughout Development, Erika Foregard, Rose De Kock, David Vollweiler

Undergraduate Research Symposium Posters

Sounds can give rise to powerful affective experiences, both positive and negative. Misophonia is an intensely negative response to sounds such as chewing, whereas autonomous sensory meridian response (ASMR) and musical chills result are experiences as positive and pleasant. Anecdotally, all of these experiences occur as early as childhood, but we know relatively little about how they develop. We investigated this question longitudinally.

Gendered Patterns Of Trauma & Ptsd Symptoms Among Latine Americans: A Mixed-Methods Analysis, Abigail Panariso, Gerardo Garcia, Melanie Garcia, Yajairy Carbrales, Mariam Sultan

Undergraduate Research Symposium Posters

Latine communities in the U.S. experience disproportionate exposure to traumatic events, contributing to behavioral health disparities such as elevated rates of posttraumatic stress disorder (PTSD) and underutilization of mental health care. Gender, as a key social determinant of health, influences both types of trauma encountered and the severity of symptoms. Little research has tackled how gender intersects with structural inequities within Latine populations, such as discrimination, immigration stress, and socioeconomic marginalization. This mixed-methods study assessed gender differences in trauma experiences and PTSD symptoms among 328 Latine American adults (148 men, 180 women) recruited through an online survey. We predicted gender …

Culturally Aware Mindfulness Training For Army Leaders: A Scalable Solution To Strengthen Mental Readiness, Katherine Dutler (Skowronski)

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This doctoral paper examines cost-effective, easily distributed mindfulness practices as a force-multiplier for psychological readiness in the U.S. Army. Daily mindfulness reduces symptom burden, raises distress tolerance, and sharpens performance—all without added equipment, appointments, or cost. However, stigma, long waitlists, and civilian-centric messaging still deter soldiers from adapting mindfulness practices. Rather than replacing clinicians, the program functions as preventive maintenance and a bridge while soldiers await care, thereby easing load on an overtaxed system. By embedding mental fitness alongside physical PT, the Army can advance its mandate to “deploy, fight, and win” with forces that are both mentally and physically …

Considerations And Guidelines For Clinical Training And Professional Practice In The Area Of Psychotherapy Termination, Elyssa L. Jampolsky

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Treatment termination occurs, invariably, in every psychotherapy relationship. Closing the therapy relationship is often a complex process and requires targeted training for psychotherapists to terminate treatment competently and in a way that preserves gains made and fosters continued client growth. Discontinuation of psychotherapy services requires practitioners to apply ethical knowledge, clinical expertise, and relational boundaries. Further, the nuances of forced, end-of-year termination in clinical training environments necessitates targeted supervision and explicit guidelines. Surprisingly, termination practices are underemphasized in training programs and in the literature. The current paper will review the extant literature related to psychotherapy termination broadly as well as …

Creating A Data Processing Pipeline With Mne-Python, Lesly Vazquez, Ananda Liz Peixoto Couto

Undergraduate Research Symposium Posters

The UNLV Psychophysiology of Emotion and Personality Lab (PEPLab) utilizes a MATLAB based pipeline to process electroencephalogram (EEG) recordings. MATLAB is a proprietary software package, which limits the ability to analyze psychophysiological data and increases the financial burden of research. To increase the accessibility of data reduction skills, we have created and tested a new pipeline utilizing MNE-Python, an open source software package (Gramfort et al., 2013). In this pilot study, we utilized existing EEG recordings and examined the relationship between the Triarchic Model of Psychopathy and Error-Related Negativity (ERN) responses across incorrect and correct trials during a Letter Shock …

Prediction Error's Influence Of Declarative Memory: A Replication, Camila Schettini, Kevin Mohawk

Undergraduate Research Symposium Posters

We often have predictions about what to expect in our everyday encounters. However, not all these predictions will be accurate. Prediction error (PE) refers to the discrepancy between expectations and actual observed outcomes, and it is believed to play a role in learning, such as in classical conditioning. Yet, its relationship to one-shot declarative memory remains poorly understood. In the present study, we aimed to replicate Greve et al. (2017, Experiment 1) by testing whether PE enhances memory. Participants first learned scene-word associations in which a specific scene image was paired with one of two category labels, “positive” or “negative”. …

Examining The Relationship Between The Initial Level Of Learning And The Rate Of Forgetting, Lex De Asis, Justin Mykovich, Rhiannon N. Soriano Smith

Undergraduate Research Symposium Posters

It has been widely contested whether the rate of forgetting is connected to the initial degree of learning. While recent studies suggest that forgetting occurs at a consistent rate regardless of how well material was initially learned, other studies argue that this conclusion depends heavily on the analytical approach and the operational definition supplied. Additionally, emerging frameworks, such as the Representation Theory of Forgetting (Sadeh et al., 2014, 2016), propose that different brain regions support distinct types of memory representations, with each governed by separate forgetting mechanisms. This study seeks to examine how the degree of learning affects the rate …

Relationship Between Caffeine Use And Eating Disorders, Hannah Segura, Maegan Nation

Undergraduate Research Symposium Posters

Eating disorders are a spectrum of cognitive, behavioral, and physical symptoms related to eating and compensatory weight management behaviors. Body image concerns can be a significant risk factor for various disorders, such as anxiety, depression and eating disorders. Additionally, eating disorders are commonly comorbid with other psychiatric disorders. Supplement usage such as performance enhancing supplements is becoming increasingly common, especially among younger populations. Using different supplements has been shown to put adolescents at an increased risk for body dysmorphia, disordered eating behaviors, as well as other potentially harmful health effects, like electrolyte complications, heart issues, or even death. Across the …

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang

Electronic Theses and Dissertations

Information is encoded and stored in three types of memory: sensory memory (SM), short-term memory (STM), and long-term memory (LTM). SM has a large capacity but retains information for only a brief period. When information transfers to STM, only a limited amount can be stored. Information in STM can then be transferred to LTM, which has a much larger capacity and longer retention time. STM is often conceptualized as working memory (WM) to highlight its role in active information processing. Due to the limited capacity of STM, it is commonly believed that STM serves as the bottleneck for information processing. …

An Examination Of Disparities In Adhd Diagnosis Between Men And Women, Julia Holloway

University Honors Theses

Attention Deficit Hyperactivity Disorder has become an increasingly popular area of study over the last decade. The rise in cases over the same period likely explains this trend, as does ADHD’s status as one of the most commonly encountered neurodevelopmental disorders. While much of this research has served as an invaluable asset to both practitioners and patients there are still blind spots which have yet to be addressed by the existing body of research. This progress in our understanding of ADHD has gone far in illuminating the biases which have set the precedent for treatment and diagnosis, however, widespread understanding …

Sex Differences In Self-Medication Patterns And Stress, Darin Challacombe, Paterson Romero

Psychology Faculty Publications

Objective: The current study sought to find out to what degree the linkage exists between sex, stress levels, and self-medication activities. Method: We used an anonymous survey in both English and Spanish and surveyed 615 participants, of which the average age was 36.5 years. For gender, participants coded themselves as “male” (n = 350) and “female” (n = 243). We did not request participants to code ethnicity. We used a demographics questionnaire, a list of substances used for self-medication along with some questions about self-medication activities, and the Perceived Stress Scale (Cohen & Williamson, 1988). Results: We found a significant …

Stigma And Barriers To Seeking Mental Health Care Among Emergency Department Providers – A Mixed Methods Study, Shannon C. White, Charlotte H. Harris, Ravindra Gopaul, Joshua M. Smyth

Student Papers, Posters & Projects

High levels of psychological distress and depression are common among clinicians working in US emergency departments [ED], yet treatment-seeking remains rare, contributing to burnout and negative well-being. Reluctance to seek care often reflects concerns about negative consequences (e.g., stigma, negative professional impact). We sought to characterize the availability of mental health resource availability, beliefs about seeking care, and barriers faced by emergency department healthcare providers. A sequential mixed-method design was employed. Phase 1 included a survey of ED physicians, advanced practice providers (APPs; i.e., nurse practitioners and physician assistants) and medical residents at an academic medical center. The survey assessed …

Engineering Faculty Articles and Research

Introduction: Parents play a vital role in supporting self-regulation and managing behaviors in children with Attention-Deficit/Hyperactivity Disorder (ADHD). However, many face barriers to accessing consistent, evidence-based support. Mobile health (mHealth) technologies offer a promising way to deliver flexible, low-burden guidance for parents on best practices and strategies to support their children's self-regulation. However, designing them is non-trivial.

Objective: This paper introduces ParentCoach, a mobile application designed to support parents of children with ADHD through brief daily lessons, reflection prompts, and skill-building activities.

Methods: ParentCoach was developed in two phases: (1) secondary analysis of qualitative data from over 30 families …

Mental Health Among Minorities In Law Enforcement Positions, Sydnee Monet Brown

Doctoral Dissertations and Projects

Law enforcement officers often deal with complex work environments, including negative public opinions, challenging legal systems, and resource constraints. These factors can compound to make officers' work more psychologically stressful. This is especially true for minority officers who also have to deal with daily incidents of prejudice, discrimination, and cultural misunderstandings within the police force. The current qualitative phenomenological study employed semi-structured interviews to investigate the experiences of minority police officers, in an effort to gain more insight into their mental health experiences. The results of this study show that discrimination, systemic issues, and stigma associated with accessing psychological help …

Examining The Relationships Among The Cognitive, Emotional, Social, And Physical Domains Of Listening-Related Fatigue For U.S. Adults Between The Ages Of 30 And 50 With Hearing Loss, Nichole Marie Wooton

Doctoral Dissertations and Projects

Adults with hearing loss (AHL) frequently report high levels of listening-related fatigue (LrF). This has mainly been attributed to the increased biopsychosocial demands involved in communication efforts for those with hearing loss (HL). Such fatigue can be measured objectively using the Vanderbilt Fatigue Scale for Adults (VFS-A-40) (Hornsby et al., 2021a). This quantitative survey study explored the relationships among gender, type of HL, and socioeconomic status (SES) and their complex connections among the four domains as defined by the VFS-A-40: cognitive, emotional, social, and physical. Using an online survey method, this research employed a strictly quantitative design to examine differences …

Analyzing Discipline Rates For Students In Grades 6-12 With Emotional Disturbances: A Comparative Study Of Four Years Before And After The Covid-19 Pandemic., Maegan N. Ramsey

Doctoral Dissertations and Projects

This dissertation investigated the trends in discipline rates for students in grades 6-12 with emotional disturbances. It compared data from the four years prior to the COVID-19 pandemic (2016-2019) to the four years following its onset (2021-2024). Emotional disturbances can significantly affect students' behavior, often leading to higher rates of disciplinary actions within school settings. However, the impact of COVID-19 on these students, particularly in terms of remote learning, school closures, and shifts in behavioral norms, has yet to be fully explored. Using archival data from multiple middle and high schools, this study examined variations in suspensions and other disciplinary …

Divine Intervention Emphasized In Ptsd Treatment Strategies, Zachary R. Kuster

Doctoral Dissertations and Projects

This study examined how theological concepts might enhance PTSD treatment outcomes by challenging existing paradigms within evidence-based interventions. While some therapeutic models acknowledge the value of integrating theological concepts within treatment, little empirical evidence explains how emphasizing the theological concepts that may already exist within evidence-based strategies may enhance the overall efficacy of treatment. In this study, an experimental group received strategies emphasizing grace, hope, and forgiveness, while a control group received strategies without these emphases. The PCL-5 psychometric assessment tool was used to measure changes across two 4-week PTSD programs that incorporated 48 strategies from the same four therapeutic …

The purpose of this qualitative phenomenological case study was to examine the lived experiences of distress, coping, and barriers to mental health support. Twenty participants were recruited through local NGOs and community networks in Morocco, and data were collected through semi-structured interviews. Thematic analysis was employed to identify recurring patterns across participants’ narratives including hunger, homelessness, and exploitation intensifying psychological strain, particularly in relation to caregiving responsibilities …

Millennials, Work Motivation, And Leadership Transition, Ngozi Maduagwu

Doctoral Dissertations and Projects

The workforce has evolved and this path was accelerated by the aftermath of the global COVID pandemic starting 2019. Traditionalist and Baby Boomer employees have been rapidly transitioning out of the workforce, which has created a need to find motivated workers and leaders to fill vacated positions. Millennials have been surveyed for their potential to fill these leadership vacuums, yet the research suggested that they present differently from other generational cohorts in terms of their motivation to work and their motivation to lead in the workplace. The purpose of this mixed methods study was to determine whether any relationship could …

Exploring The Relationship Between Becoming A Parent, Goal Orientation, And Productivity, Among Self-Employed Entrepreneurs, Andrew Dean East

Doctoral Dissertations and Projects

This quantitative study explored the relationship between parenting status and goal orientation and productivity among self-employed entrepreneurs. Using a sample of 471 participants, the study compared entrepreneurs with and without children under five years of age living at home to examine group differences, relational patterns, and potential moderation effects. No statistically significant differences were found in goal orientation or productivity between parents and non-parents, indicating that early-stage parenting does not inherently hinder these traits. However, a small but statistically significant positive correlation was observed between goal orientation and productivity, suggesting that individuals with higher internal motivation reported slightly greater productivity, …

Healthcare burnout increases the risk of harm to healthcare workers as well as their patients. Participants of the study included healthcare workers with direct experience in burnout. The aim was to understand their personal experiences, the actions, both individual and organizational, that contribute to burnout, and the methods that have been used with varying success to address it. The study also explored the connection between self-determination theory and the areas-of-work-life model, along with participants’ insights into contributing actions and …

Unraveling The Lullabies Of Learning: Exploring The Role Of Individual Components Of Infant-Directed Speech In Language Learning, Stephanie L. Lopez

LSU Doctoral Dissertations

Children learn language more effectively from infant-directed speech (IDS) than adult-directed speech (ADS). Three experiments were run (a pilot and two full experiments) testing the effects of pitch and pitch variability on segmenting a target word out of the speech stream and then associating it to an object. Visual prosody via eyebrow movements and lip contours were added as additional cues after the Pilot Study. Additional factors included after the Pilot Study were shortened sentences from 10 syllables each to seven syllables each, shortened target words from three syllables to two syllables, consistent syllable onset of target words, and two …
