Experiences Of Marginalization At The Intersection Of Race, Ethnicity, And Disability In Higher Education, Nora L. Portillo

Theses, Dissertations and Culminating Projects

Black and Latine college students with disabilities navigate higher education at the intersection of racism and ableism, yet their experiences remain underexamined. Autism and ADHD are particularly underrepresented in research and public discourse; moreover, unlike other disability categories in which students of color are overrepresented, Black and Latine children are less likely than white children to be accurately identified, and both disabilities are often framed around white prototypes. Guided by Disability Critical Race Theory, the present exploratory qualitative study used semi-structured interviews with ten undergraduates identifying as Black and/or Latine and with ADHD and/or on the autism spectrum attending a …

Covid-19 Pandemic-Induced Social Isolation: A Hermeneutic Phenomenological Exploration Of Age And Time, Renee Reedy

Dissertations and Theses

Lockdown measures during the COVID-19 pandemic fundamentally altered social functioning, creating an urgent need to understand the lived experience of isolation across life stages. This qualitative hermeneutic phenomenological study explored how age and time shaped social isolation during the pandemic. Sixteen participants from three-generation households—adolescents (n=5), adults (n=6), and older adults (n=5)—were interviewed approximately five years post-isolation. Recruitment occurred through ResearchMatch, and interviews were conducted between February and March 2025. Participants represented diverse racial, ethnic, and geographic backgrounds, with isolation periods ranging from 27 to 426 consecutive days (¯x = 165 ± 124 days). Data analysis followed Gadamer’s hermeneutic circle …

Evaluating Motivation In Stem Education: A Positive Self-Talk Intervention, Tiffany L. Copeland

PCOM Psychology Dissertations

This study evaluated a social-emotional learning intervention that taught positive self-talk to high school students from underrepresented minority groups in science, technology, engineering, and math (STEM). The setting of this study was a place-based program that immersed students in hands-on STEM activities while located in Philadelphia’s life science hub. Before taking a science assessment, students set effort-based goals and learned to say self-talk statements such as “I will give my best effort” and “Even when it's hard, I will give 100%.” This mixed-methods program evaluation compared pre- and post-intervention data using a paired-samples t-test, linear regression, and correlation analyses. Data …

Understanding The Role Of School Resource Officers In Addressing Students’ Mental Health Needs: A Phenomenological Study, Ryan Christopher Vinzant

Dissertations and Theses

Since the 1990s School Resource Officers (SROs) have been commonly employed in schools throughout the United States. However, their jobs may look very different depending on what setting they are in and the different administrative policies governing their work. Throughout this time, researchers have focused on the different roles that SROs have within the educational environment and how these roles are put into action when interacting with students. However, there have been limited studies exploring the role SROs play when interacting with students who are experiencing mental health problems or experiencing a mental health crisis. Mental health problems have become …

What Race Means For Health Among Black Americans: How Microaggressions Shape Self-Efficacy And Readiness For Behavior Change, Amanda Lee Almond

Publications and Research

Objectives: Persistent racial disparities in cardiovascular health among Black Americans reflect not only structural inequities in the United States, but also the racialized meanings of cardiovascular disease reproduced through public and private health communication. Drawing on ecological systems theory, this research examines how beliefs linking race and cardiovascular disease are reinforced through routine clinical interactions and how these meanings shape health behavior change. Method: Across two experimental mixed-methods studies, a model integrating ecological, social–cognitive, and behavior-change frameworks was tested. In Study 1 (N = 374), health-message framing was experimentally manipulated to examine effects on self-efficacy and decisional balance while controlling …

Experiencing Objectification In Platform Work: Food Delivery Riders’ Accounts Of Organizational Absence And Self-Valuation, Emerald Jay D. Ilac, Ma. Tonirose D. Mactal, Clarisse Aeaea M. Kilboy

Leadership and Strategy Faculty Publications

This study aimed to explain how food delivery platform riders experience objectification in the context of platform-based work, with particular attention to how organizational practices and leadership shape experiences of marginalization, dignity, and voice. A qualitative design was employed using Descriptive Phenomenological Analysis. In-depth interviews were conducted with nine food delivery platform riders to describe the essential structures of their lived experiences of objectification. Subaltern Theory was used as an interpretive lens in making sense of the findings. Five experiential themes were identified: (1) leaders’ non-presence resulting in perceived abandonment, (2) leaders’ devaluing of food delivery riders, (3) social devaluation …

Merger Crisis Role-Play: Organizational Behavior In Action, Jyro B. Triviño

The Effects Of Surf Film Viewing As A Dialectical Behavior Therapy-Aligned Intervention For Trauma-Related Symptoms, Ryan Papero

Senior Honors Theses and Projects

This study examined whether viewing a surf film aligned with Dialectical Behavior Therapy (DBT) principles would reduce emotion dysregulation among trauma-exposed adults. Participants (N = 14) with self-reported childhood trauma were randomly assigned to view either The Endless Summer or a neutral industrial documentary. Emotion regulation was assessed using pre- and post-intervention Difficulties in Emotion Regulation Scale (DERS) scores. An independent samples t-test comparing change scores indicated that the control group demonstrated a greater mean reduction in DERS scores (M = 6.13, SD = 5.22) than the surf group (M = 2.50, SD = 3.08); however, this difference was not …

The Effects Of Nature Exposure On Workplace Engagement, Allison Emmons

Senior Honors Theses and Projects

The idea that nature is beneficial to humans is somewhat unclear in the field of psychology. Many studies have found that exposure to natural elements can improve human emotions and performance on cognitive tasks. However, there are inconsistencies in the literature regarding whether both outcomes can be enhanced at once. There is also limited research on how nature can impact attitudes about the environment and tasks at hand. This study seeks to examine whether or not incorporating natural elements into workplaces improves employee performance and engagement measures, such as decision-making quality, job satisfaction, job motivation, and current emotional state. This …

“I’M Throwing The Red Flag”: Online Peer Responses To Teen Descriptions Of Abusive Relationship Behaviors Posted On Reddit, Kyla M. Cary, Morgan E. Pettyjohn, Erin Nolen

Faculty Publications – Psychology

Adolescents in the United States experience abusive relationship behaviors at alarming rates; yet formal education on navigating harmful relationship dynamics is lacking. Thus, many teens use the internet to disclose abuse experiences and seek information or advice from their online peers. To better understand the types of responses, advice, and information teens receive from their online peers, we analyzed peer-to-peer discussions about abusive relationship behaviors from teens in the Reddit community r/teenrelationships. Using qualitative content analysis, we analyzed comment responses (n = 154) to Reddit posts (n = 56) in which teen users discussed experiences of interpersonal harm …

A Macrocognitive Design Taxonomy For Simulation-Based Training Systems: Bridging Cognitive Theory And Human-Computer Interaction, Jessica M. Johnson

Virginia Digital Maritime Center (VDMC) Faculty Publications

Simulation-based training systems are increasingly deployed to prepare learners for complex, safety-critical, and dynamic work environments. While advances in computing have enabled immersive and data-rich simulations, many systems remain optimized for procedural accuracy and surface-level task performance rather than the macrocognitive processes that underpin adaptive expertise. Macrocognition encompasses higher-order cognitive processes that are essential for performance transfer beyond controlled training conditions. When these processes are insufficiently supported, training systems risk fostering brittle strategies and negative training effects. This paper introduces a macrocognitive design taxonomy for simulation-based training systems derived from a large-scale meta-analysis examining the transfer of macrocognitive skills from …

Practical Considerations For Conducting Canine Behavioral Science, Lucrezia Lonardo, Madeline H. Pelgrim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Research on behavior in domestic dogs (Canis familiaris) has increased rapidly recently due to the interest in them as pets, working dogs, and model species for understanding evolution, domestication, and even human health. This interest in canine behavioral science has resulted in the creation of dozens of dog lab worldwide, with more starting every year. Our aim here is to review practical issues that potential dog researchers might consider when deciding how to set up a dog lab and conduct research in canine behavioral science. We hope that this can offer a path forward in promoting high-quality, cutting-edge …

Queer Experiences Of Double Disadvantage: The Moderating Effects Of Rejection On The Relationship Between Adverse Childhood Experiences And Attachment Style, Isabella Kinney

Psychology Honors Papers

This thesis examines how intersecting forms of disadvantage – particularly experiencing identity-based rejection and adverse childhood experiences (ACEs) – can negatively impact a queer-identifying individual. Previous research highlights that both ACEs and rejection are linked to poor mental health and insecure attachment patterns within LGBTQ+ populations. This study aimed to determine whether rejection serves as a moderator for the relationship between ACEs and attachment. Data was collected through an anonymous online survey of 81 participants recruited from Connecticut College and Connecticut’s LGBTQ+ Justice and Opportunity Network, and included measuring ACEs, rejection experience, and attachment patterns. Using a regression and moderation …

The English You Speak Matters: Immigrants, Phonological Roots, And Psychological Perspectives On Accent Discrimination, Sophia Hauschildt

Psychology Honors Papers

Accent serves as a highly salient social cue that influences how speakers are perceived, particularly in multicultural contexts where linguistic diversity is increasing. The present study examined how English accent affects evaluations of speaker warmth and competence, and how individual differences in cultural intelligence and colour-blind racial attitudes shape these perceptions. Using a between-subjects experimental design, participants (N = 225) were randomly assigned to listen to a standardised speech passage presented in one of five accents: General American English (GAE; control), Spanish-accented English, Chinese-accented English, Hindi-accented English, or Filipino-accented English. Participants then completed measures of speaker evaluation based on …

Use Of Ai In Expert Testimony: Understanding The Attorney Perspective, Emma S. Puntin

Psychology Honors Papers

Artificial Intelligence is becoming increasingly incorporated into different aspects of society, including our legal system. AI has potential to enter into legal proceedings through the introduction of its evidence in case and expert witness testimony. Expert witnesses are called to offer knowledge on matters relevant to a case and can vary in specialization. This study aimed to explore how attorneys view experts who use AI and how they would approach this in a courtroom setting. Structured interviews were conducted with ten attorneys from various jurisdictions. During these interviews, attorneys were asked what they have encountered during their work in the …

Investigating The Viability Of Fully Online Asynchronous Physics Instruction In Formal Education, Clifton W. Massey-Noel

Physics Dissertations

In this dissertation we present results from two consecutive investigations into the fully online asynchronous modality in Physics Education. We first discuss the efficacy of a fully online asynchronous section of Modern Physics held in Fall 2024. The asynchronous section is compared with four prior partially-flipped sections of the same class, two of which were held in-person, and two of which were held synchronously online. Results suggest that all three modalities can be made to be about equally as effective. We also discuss the efficacy of a fully online asynchronous section of Calculus-Based Introductory Mechanics held in Fall 2025. The …

Conch Gone? Examining Cultural Preservation Through Bahamian Menu Analysis, Adiah J. Saunders

Undergraduate Honors Theses

Social identity theory and acculturation theory expose how cultural practices, such as cuisine, can adapt due to external pressures. In The Bahamas, external pressure from the tourism industry shapes many aspects of public life, by analyzing menus we can see how cultural identity resists or succumbs to change. This study examined how Bahamian cuisine is represented on restaurant menus in Nassau, New Providence amid a dominating tourism industry. Using a stratified random sample of 30 restaurants, 1,155 menu items were coded for cultural origin, cultural language use, promotional features, as well as pricing. The results show that international dishes appear …

Professional Standards For School-Based Behavior Analysts (2nd Edition), Selena J. Layden, Emily Muise, Karen L. Berlin, Samantha Gregory, Daniel Irwin, Kaylan Long, Daria K. Lorio-Barsten, Jennifer L. O’Berry, Hannah Riddle

Human Movement Studies & Special Education Faculty Publications

Public educational settings are unique and complex environments that require specific knowledge and skills for the professionals that work in these environments. School-based behavior analysts can be a great asset to public schools. However, these professionals must be able to firmly understand and perform the responsibilities of a behavior analyst in collaboration with educators and service providers in a public school setting. The presence of behavior analysts in public schools is still relatively new, when compared with other specialized services. Therefore, behavior analysts, teachers, administrators, and others should focus on collaboration to promote the success for all stakeholders with an …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

The Effect Of Automated Self-Monitoring On The Behavior Of Individuals Diagnosed With Pre-Diabetes Or Type 2 Diabetes, Leti Phillips Armenta

Type 2 diabetes (T2D) and prediabetes affect millions of individuals in the United States and require effective self-management strategies to reduce glucose variability and improve health outcomes. This study evaluated the effects of automated self-monitoring using the Dexcom G7 continuous glucose monitor (CGM) on glucose management and health-related behaviors among adults diagnosed with prediabetes or at risk for T2D. A repeated-measures design was used to asses’ participants across two distinct 10-day periods. Data included CGM glucose readings, self-report questionnaires, and social validity measures. Results indicated that participants demonstrated reduced glucose variability, fewer prolonged glucose spikes, and increased engagement in health-related …

Reward Deficits In Co-Occurring Social Anxiety And Depression: The Roles Of Anhedonia, Boredom, Loneliness, And Covid-19 Social Restriction, Nathan M. Hager, Alicia L. Milam, Hannah C. Hamrick, Benjamin Swanson, Matt R. Judah

Psychology Faculty Publications

Prior research points toward reward deficits as crucial to the link between social anxiety disorder and major depressive disorder. However, studies have not explored specific types of reward deficits or how social-environmental factors may impact them. The current study examined whether the indirect effects of three reward deficits (anhedonia, boredom, and loneliness) accounted for the connection between social anxiety and depression. Questionnaires were collected in a sample of college students (N = 523) during the first year of the COVID-19 pandemic, allowing examination of environmental stressors (i.e., remote learning and current friend network size) on reward deficits. Indirect effect models …

Responding To Suicide Loss: A Guide For Clinicians In Therapy With Suicidal, Grieving Adolescents, Brianna Jurosic

Psychology Doctoral Specialization Projects

Psychologists have spent years attempting to conceptualize what causes individuals to become suicidal and ultimately understand why individuals choose to die by suicide. Dr. Thomas Joiner (2005) developed the Interpersonal Theory of Suicide in an attempt to summarize and build upon previous models. The Interpersonal Theory of Suicide is built upon three factors: perceived burdensomeness, thwarted belongingness, and the acquired ability to enact lethal self-injury. Joiner theorized that perceived burdensomeness and thwarted belongingness together create the desire for suicide, and the ability to enact lethal self-injury adds the final piece that moves the desire toward action (i.e., a suicide attempt). …

Thrive Together: A Culturally Responsive Group Intervention To Support Emotional Regulation And Behavioral Health Among Underserved Middle School Youth, Cherish Harris

Psychology Doctoral Specialization Projects

Mental health concerns among children and adolescents continue to represent a significant public health concern, particularly among underserved and minority youth who experience disproportionate exposure to systemic inequities, chronic stressors, and barriers to mental health care. Schools frequently serve as primary points of contact for youth experiencing emotional and behavioral difficulties; however, many settings lack accessible interventions that adequately address both internalizing and externalizing concerns. The purpose of this doctoral project was to develop Thrive Together, a culturally responsive group intervention designed to support middle school students experiencing emotional, behavioral, and interpersonal challenges. The intervention was developed in response …

Pathways To (Prevent) Radicalization: How Uncertainty And Identity Complexity Shape Vulnerability, Michelle Blaya Burgo

CGU Theses & Dissertations

Violent radicalization and politically motivated violence are pressing concerns that threaten global peace, security, and social cohesion. Violence is costly, in both lives and resources, and reactive measures have failed to decrease its occurrence. In a world marked by uncertainty where some degree of conflict is unavoidable, the focus should be on preventing violence. Previous research had demonstrated that various group- and individual-level factors can lead people to radicalize; this work extends that research by introducing social identity complexity (Roccas & Brewer, 2002) as a potential buffer against radical pathways. The current research proposed that complex identity structures – defined …

We Can Be Heroes: Sustaining Vitally Engaged Social Heroes In A Heroic Organization (Act Up/New York), Michael Condren

CGU Theses & Dissertations

Contextual factors are particularly important in understanding social heroism, which is characterized by heroic action in the service of existing and emerging community values, principles and ideals (Franco et al., 2011). Social heroism almost always entails serious risks for the hero and frequently requires committed action over long time periods to achieve positive social change. Unlike other types of heroism, social heroism frequently emerges from and is enacted through organizations. However, heroism research has focused largely on individual factors involved in different types of heroic actions, such as character, moral development and courage. The goal of this study was to …

Work Disengagement: Motivational Regulation Shaped By Psychological Need Frustration And Perceived Injustice, Stephanie R. Dailey

CGU Theses & Dissertations

Employee disengagement represents a persistent global challenge, yet remains theoretically underdeveloped and is frequently conflated with burnout, behavioral withdrawal, or deviance. Building on Kahn’s (1990) original conceptualization, this dissertation reconceptualizes disengagement as a distinct motivational state characterized by the withdrawal of cognitive, emotional, and physical energies from role performance. Drawing on Self Determination Theory (Ryan & Deci, 2000), Conservation of Resources theory (Hobfoll, 1989), and the Job Demands–Resources model (Bakker & Demerouti, 2007), I test a model where disengagement emerges as a motivational response to psychological need frustration, where organizational justice functions as an upstream contextual antecedent. Two complementary studies …

Momentary Psychological Well-Being Of Informal Caregivers Of Young Adult Cancer Patients: A Feasibility Study, Ximena Giesemann

CGU Theses & Dissertations

While caregivers of cancer patients across all ages experience fluctuations in psychological well-being, informal caregivers of young adult cancer patients (ICCYAs) may be especially vulnerable due to the distinctive developmental context of the young adult cancer patient and the unique challenges of facing cancer during this life stage. However, research that examines ICCYA psychological well-being is limited and utilizes methodologies that are insufficient in capturing both the dynamic nature of psychological well-being and the ICCYA role. As a result, there is a notable gap in the literature regarding how ICCYA psychological well-being unfolds, and the moment-to-moment factors associated with it. …

American Spirits: The Impact Of Social Setting On Voter Turnout, Annika Lindberg

Scripps Senior Theses

Low voter turnout has characterized American elections for the past century, raising ongoing concerns about democratic representation. Although scholars agree that low turnout is problematic, they differ on which factors most strongly influence participation. This thesis examined whether creating a celebratory, patriotic Election Day environment modeled after Fourth of July festivities increased voter engagement.

Using two complementary methods, the research evaluated the effects of celebratory Election Day settings on voting behavior. Study 1 used a partial field case study, comparing turnout after Election Day parties held for three student organizations at a small California liberal arts college with turnout from …

Beyond Ssris: Omega-3 Fatty Acids And The Neurobiology Of Impulsivity In Borderline Personality Disorder, Sujean Doo

Scripps Senior Theses

Impulsivity is a central and clinically significant dimension of Borderline Personality Disorder (BPD), and is strongly associated with self-harm, aggression, and suicide risk. Despite its prognostic importance, pharmacologic management of impulsivity in BPD remains inconsistent. Selective serotonin reuptake inhibitors (SSRIs) are frequently prescribed; however, randomized controlled trials demonstrate limited efficacy for impulsive-aggression, and some patients experience a paradoxical behavioral activation. Meta-analytic and systematic reviews further suggest that mood stabilizers and second-generation antipsychotics may outperform antidepressants, yet no specific medication is indicated to target impulsive behavioral dyscontrol.

This thesis synthesizes findings from systematic reviews, randomized trials, and neuroimaging research to evaluate …
