U.S. Black Men’S Perceptions Of The Similarities And Interplay Among Mind-Body Practices, Spirituality, And Religion: A Qualitative Study, Khanh Pham

Theses and Dissertations

This qualitative study explored U.S. Black men’s perceptions of relations among mind-body practices (MBPs), spirituality, and religion to understand how these factors might influence Black men’s health. Reflexive thematic analysis was used to analyze data from individual semi-structured interviews with 18 Black male MBP instructors. Five themes were generated. The themes were (1) spirit(uality) is the foundation for Black men’s experience of life seen and unseen, (2) MBPs and religion are rooted in spirituality, (3) MBPs, religion, and Black culture share common characteristics, (4) MBPs and religion facilitate holistic wellbeing, and (5) confusion and negative perceptions about MBPs, spirituality, and …

Quiet Hills, Restless Hearts: An Intersectional Exploration Of Lgbtq+ Religious Journeys In Appalachia, Allison S. Monroe, Stacey L. Williams

McNair Culminating Research Projects

Many researchers have utilized Meyer’s (2003) minority stress model to examine the social factors influencing the daily lives of LGBTQ+ individuals. Previous research has looked at negative mental health outcomes for LGBTQ+ individuals (McGraw et al., 2023), the presence of religious stress for this community (Page et al., 2013), and religious journeys of these individuals (Halkitis et al, 2009).  However, few studies have examined the intersection of religion, LGBTQ+ identity, social support, and the overarching values of Appalachian culture. The proposed study seeks to add to the literature and understand the breadth of these experiences by employing qualitative semi-structured interviews. …

Entre La Lucha: Familismo And Well-Being Of Latino Immigrant Families Navigating Manual Labor And Anti-Immigrant Sentiment, Faviola Robles Saenz

Dissertations and Theses

The United States' history of treatment toward Latino immigrants has been shaped by anti-immigrant sentiment and exploitative labor practices, creating psychological violence that harms their families' well-being. Although previous research has examined anti-immigrant sentiment, labor conditions, and familismo among Latinos, these areas are often studied in isolation, with limited attention to their intersections and how they are experienced across generations. Informed by history, prior research, and my lived experiences, this study qualitatively explored the intersections of anti-immigrant sentiment and parents' manual labor to understand how these contexts shape familismo and well-being among Latino immigrant families. This work was grounded in …

How Lesson Type Shapes First-Grade Scienceengagement And Enjoyment, Stella Cybulski, Brooke Towner, Joy James

Journal of Youth Development

Although traditional classroom instruction often emphasizes passive forms of learning, growing evidence highlights the value of active play in promoting curiosity and conceptual development. Grounded in guided play theory, this study investigated how young learners experience science lessons across three instructional contexts: indoor inactive, indoor active, and outdoor active. Thirty-two first-grade students in a Title I laboratory school completed an enjoyment survey and drawing task following each lesson type. Results demonstrated that active play, particularly in outdoor contexts, was associated with higher enjoyment and more dynamic depictions of science learning. Thematic analysis of drawings indicated that students connected more deeply …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

Healing Historical-Intergenerational Trauma And Colonial Soul Wounds With Ancestral Healing Practices And Psychosocial Limpias: An Ofrenda For The Salvadoran Community, Joanna D. Beltrán Girón

Dissertations, Theses, and Capstone Projects

In 1992, the United States-backed Salvadoran military and the leftist guerrillas signed the Chapultepec Peace Accords, which put an end to a 12-year war in El Salvador that resulted in 75,000 deaths, 12,000 forced disappearances, and half a million internal displacements. Around 85% of the reports made by survivors of the war attributed the violence to state agents, paramilitary groups, and death squads.While taking into account this history of state violence, this dissertation is interested in the psychosocial aftermath of the war and in how survivors integrate healing practices in their lives in response to the painful memories their bodies …

Minding The Body: A Mixed Methods Analysis Of Somatic Experiences During Therapeutic Psychedelic Use, Daniel Grossman

ETDs from 2020-2029

Somatic phenomena, including shaking, spontaneous movement, vocalization, and purging, are commonly reported during psychedelic-assisted therapy (PAT). However, despite their perceived importance to some users, their role in the therapeutic process has remained largely unexamined. This mixed-methods study provides the first systematic investigation of these experiences during therapeutic psychedelic use, with particular attention to observable bodily responses (OBRs) and release-like somatic experiences (RLSEs), defined as a subset characterized by sensations of physical discharge. An online retrospective survey (N = 286) assessed the prevalence of OBRs and RLSEs, and their relationships with body awareness, bodily dissociation, emotional breakthrough, and perceived therapeutic benefit. …

Well-Being, Resilience, And Trauma During Migration: A Mixed Methods Study Of Venezuelan Migrants In Transit, Margaret S. Port

Dissertations

A substantial body of research has examined the psychological impact of experiences preceding and following migration, yet comparatively little attention has been given to the psychological toll of the migration journey itself. Moreover, due to the relative novelty of the Venezuelan migrant crisis and the community’s arrival in the United States, the psychological impact of Venezuelan migrants’ unique migration experience has been underexamined. This study utilized an explanatory sequential mixed methods design to investigate the relationships between well-being, resilience, and trauma among Venezuelan migrants in Chicago, Illinois, while also exploring their lived experiences of the migration journey. Study participants (n …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

La Espiritualidad: Transmitting Peruvian Culturo-Spiritual Elements Into Occidental Systemic Spaces, Deisy Amorin-Woods

Research outputs 2022 to 2026

This paper is a decolonising, Indigenous qualitative inquiry that integrates elements of critical autoethnography, narrative methods and conceptual analysis to explore how Peruvian Andean cosmology can inform contemporary systems thinking and family therapy practice. Writing as a mestiza, a Peruvian migrant in Australia, the author traces the lived experience of cultural erosion within Western, individualistic contexts and her reconnection with ancestral Andean teachings. These teachings—rooted in reciprocity, ecological attachment, collective responsibility and relational balance—are presented as living epistemologies that offer timely contributions to working therapeutically. The author examines core Andean concepts including ayll (kinship-based community), ayni (sacred reciprocity), Yachay (aprenderes …

Well-Being Of University Students In Singapore, Tina Li Yi Ng, Andree Hartanto, William Tov

Research Collection School of Social Sciences

Singapore provides an insightful case study for university student well-being due to its national culture of competitiveness. Amid a meritocratic society that valorizes academic success as the path to securing one’s future (Ho et al., 1998), educational attainment is central to Singaporean university students’ well-being (Inter-University Network, 2022). In response to Singapore’s increasing incidence of mental health challenges among young adults (Ministry of Health Singapore, 2022), the government and higher education institutes have sought to destigmatize mental health and improve accessibility to related resources. In this chapter, we review the literature on the well-being of Singaporean university students. We situate …

Looking Upwards And Out: Comparing Buddhist And Humanist Frameworks For Enlightenment, Mason Mckinney-Best

University Honors Theses

During the Zen Boom of the 1950's, Psychologists, Philosophers, and other western thinkers were exposed to Zen Buddhism and began to harness some of the principles for use in Psychology. In the last 3 decades, Psychologists have renewed their interest in Buddhism, especially as "fourth wave" cultural competence has become an important part of Psychological practice. While work has been done in developing clinical applications of Buddhist practices, more could be found in Buddhism for the person who wishes to become more healthy.

Within Psychology, one figure had exactly that objective: Abraham Maslow. His work on Self-Actualization has been …

Long-Covid And Cognition, Mychael Bruce

Dissertations

COVID-19 is an evolving virus that can harm the body’s respiratory and cardiovascular systems. Directly related to COVID-19 are individuals who do not recover from their initial infection, making them long haulers. Long-COVID is transitioning from a range of isolated phenomena to higher prevalence rates in patients who contracted COVID-19. Many individuals report issues with cognitive function, referred to as ‘brain fog’, that affect memory, attention, and even language skills. This literature review addresses the available research on Long-COVID and how persistent infection correlates with cognitive difficulties. It aims to explain the neurobiology of Long-COVID and how Long-COVID interacts within …

In summer 2022, trained research staff conducted six focus groups with 27 girls from urban and rural communities in the Midwestern United States. Participants reviewed the original program curriculum and provided feedback on program activities, structure, relationships, and implementation strategies. Sessions were audio recorded, transcribed verbatim, and analyzed thematically using qualitative software and manual review. Girls provided feedback on multiple program components, resulting in 12 themes aligned with eight established features of positive developmental …

Cognitive Predictors Of Functional Recovery After Traumatic Brain Injury, Disha A. Thakkar, Charles J. Golden

Archives of Assessment Psychology

This study examined whether the Brief Test of Adult Cognition by Telephone (BTACT), administered during acute rehabilitation, improved the prediction of 5-year functional outcomes after traumatic brain injury (TBI) beyond standard demographic and injury-severity variables. Data were obtained from the Traumatic Brain Injury Model Systems (TBIMS) National Database (N = 6,880; enrolled 2017 onward). Missing data were handled using multiple imputation (20 datasets). Hierarchical multiple regressions were conducted with the Functional Independence Measure (FIM) and the Glasgow Outcome Scale–Extended (GOS-E) as outcome measures. Demographics (age, sex, education, race) were entered in Block 1, injury severity indicators (post-traumatic amnesia [PTA] duration, …

Prior Traumatic Brain Injury As A Predictor Of Cognitive Deficits After Moderate-To-Severe Injury, Disha A. Thakkar, Charles J. Golden

Archives of Assessment Psychology

Prior traumatic brain injuries (TBIs) are common among individuals who later sustain a moderate-to-severe TBI (msTBI), and cumulative injury models suggest repeated TBIs may worsen long-term cognitive outcomes. This study tested whether prior TBI history independently contributes to cognitive performance one year after an index msTBI beyond demographic and injury-severity factors. Data were drawn from the Traumatic Brain Injury Model Systems National Database (N = 6,880 enrolled since 2017). 2,773 participants completed the Brief Test of Adult Cognition by Telephone at one-year follow-up. Hierarchical regression models evaluated whether prior TBI history accounted for incremental variance in overall cognitive status and …

Improving Human-Wildlife Coexistence: An Ecological And Educational Approach To Rewilding Grizzly Bears (Ursus Arctos Horribilis) In California, Amanda C. D. Rosales

Master's Projects and Capstones

Megafauna extinction during the Holocene has been both caused and amplified by climatic changes and human influence. By the last half century, large carnivores were diminished in Europe and the United States, but policies increasingly addressed species decline and their territories expanded. This research examined large carnivore rewilding across the European Union and United States, specifically for rewilding brown bears, Ursus arctos, in historic habitat. Next, case studies for the health status of climate-impacted whitebark pine, Pinus albicaulis, a high energy food for bears, was assessed. Ultimately, research case studies, human perspective surveys, and the California Department of Education content …

Numb., Anna Rapson

Masters Theses

Social media platforms, from their conception, posed a break in the lived experience of the average human being’s day to day routines. Although access to information has always been shaped by portals into other lived realities—through photojournalism, print legacy media, news broadcasts both on radio and television—social media has posited a novel phenomenological architecture where borders between embodied reality and perception of lived experience are simultaneously blurred and reinforced. This morphed duality of consciousness positions the body and mind in tension, deconstructing pre-social media conceptions of the ontology of lived experience. In a digital world shaped by limitless input by …

Finding A Way Out Of The Filter Bubble: The Confusion Of A Heavy Social Media User, Longwen Miao

Masters Theses

This thesis studies how algorithmic recommendation systems reshape visual perception, aesthetic judgment, and the construction of selfhood within contemporary digital culture.

Everything begins with the experience of repeatedly encountering algorithmically recommended content on everyday digital platforms. On these platforms, images, sounds, and social interactions are continuously selected, repeated, and reorganized by predictive systems, forming an environment in which perception is constantly structured and adjusted.

From this observation, the research raises two central questions: how do algorithmic recommendation systems reshape visual perception, aesthetic judgment, and self-recognition, and how might these systems be intervened in or made perceptible through artistic practice? Within …

Domestic Travelers: Transparent Machines, Hollow Bodies, Hanyi Wang

Masters Theses

Digitization is not a modern invention. Derived from the concept of fingers, this mindset of packing information into quantifiable, interchangeable units sounds mechanical, yet eerily physical. Try to imagine: a ghostly hand with millions of fingers with the same length, likeness, and function. Under the worldview of Digital Narrative, we live in a digital simulation: everything is representable with quantifiable units, fluid across media. Yet under this spectacle of convenient abundance, something is missing. The Unknowables are replaced with arbitrary symbols, while the Uncategorizables are omitted. This is a framework that cannot accommodate human subtleties and complexities. One needs to …

Until The Ground Breaks, Annie Hu

Masters Theses

Until the Ground Breaks explores the complex relationship between personal memory, embodied experience, and internalized "archival logic." By examining long-term cross-cultural diasporic experiences and the shifting dynamics of family narratives—including the sensory experiences and fading memory of a grandmother, a father's correspondence that acts as a textual record of emotional logic, and the continuous revision of family history—this thesis dissects the psychological tremors that occur when the illusion of a singular, stable memory archive collapses. This research rejects the view of memory as a static container of truth, revealing it instead as a dynamic, unstable, and constantly rewritten living system. …

Care Ecologies Between Knots, Eliza R. Marris

Masters Theses

Discarded fibers like raw wool behave the way harm reduction does. Harm reduction resists stigma and works to move beyond assumptions and oversimplifications of substance use and addiction. Wool is irregular, complicated, and emotionally charged. It resists compression and maintains its own being even when pulled apart. Working with raw wool is in relationship with complexity, as is harm reduction.

At its core, harm reduction is grounded in thoughtfulness and empathy towards people, their lived experience, and its nuances. It is a witness to lives, memories, and imprints, acknowledging the entangled realities of addiction. Our detachment from fiber remainders, materials …

Reading Exercise (You Are The Hero): Dedicated To The Providence River Under The Mall, 02.17.2026, Deborah Fischer

Masters Theses

This play uses the performative potential of guilt, forgiveness, and self-help techniques as a catalyst for a new dynamic, one in which the pursuit of a false narrative, along with the structures it generates, becomes more real than reality itself. It employs “bad acting” and the practice of cold reading to stage a series of acts that function as an entry point into one’s own psyche, leveraging the peripheral space around familiar actions to allow chance, free will, and the experience of “real time” to temporarily come into effect. PLAYER 1: The bad actor is the most utopian one. CLOWN: …

Canine And Equine Behaviors In Therapy: An Exploratory Multiple Case Study, Sarah E. Montano

Doctoral Dissertations and Projects

Animal-assisted therapy (AAT) utilizes animals in the treatment of clients with mental health disorders. Dogs and horses are often used in this modality, but studies have not explored the use of these two types of animals in AAT to discover if there are similarities and differences in the behaviors the animals display during therapeutic sessions. The present study utilized interviews with clinicians providing canine-assisted therapy or equine-assisted therapy to investigate similarities and differences. The interviews were audio and video recorded and transcribed verbatim. Thematic analysis was used to identify key themes regarding the behaviors of the animals. The analysis showed …

This study examined the relationship between naturally occurring farm animal interactions and overall well-being among rural adults living in the central Appalachian region, specifically western Maryland, south-central Pennsylvania, and the eastern panhandle of West Virginia. A cross-sectional, correlational design was used to compare adults with at least five hours of naturally occurring farm animal contact per week to those with less than one hour of contact per week. Overall well-being was measured with the PERMA-Profiler, and heart rate variability (HRV) was measured using wearable devices as a physiological indicator of autonomic health. Grounded in polyvagal theory, the biophilia hypothesis, and …

Dialogue Between Mind And Algorithm: Deep Symbiosis Of Psychology And Artificial Intelligence, Xiaolan Fu, Zheng Yan

Bulletin of Chinese Academy of Sciences (Chinese Version)

As artificial intelligence (AI) evolves from a supportive tool into a collaborative partner, the convergence of psychology and AI is gradually shifting from one-way application toward deep symbiosis. This study discusses the mutual empowerment resulting from their interaction, as well as the challenges they face and potential pathways to breakthroughs. On the one hand, psychology empowers AI by enhancing its human-like intelligence and social adaptability through cognitive modeling and ethical constraints; on the other hand, AI empowers psychology by leveraging multimodal data and algorithmic models to revolutionize psychological assessment and intervention methods. This deep symbiosis requires a clear-eyed acknowledgment of …
