Impact Of Traditional (Non-Affirming) Black Church Affiliation On Exploration Of Sexual Identity For Black Assigned Female At Birth Lgbq+ Individuals And The Associated Mental Health Risk, Aurielle J. Sutton

Doctoral Dissertations

This dissertation explored the impact of Black traditional church upbringing on the sexual and religious identity development, including the subsequent mental health risk, for Black assigned female at birth (AFAB) LGBQ+ individuals. Studies conducted on Black AFAB LGBQ+ individuals are limited, especially in terms of  assessing their experiences in sexual identity development based on religious upbringings. Studies have overlooked the experience of LGBQ+ Black AFAB individuals navigating sexual orientation development and religious and racial identities. Studies have greatly favored Black gay men and supported health risks such as HIV. In the present study, twelve Black AFAB Queer individuals participated in …


Reflecting On Psychotherapy In Adolescence: A Qualitative Analysis Of Processes Of Change, John Parigger May 2027

Reflecting On Psychotherapy In Adolescence: A Qualitative Analysis Of Processes Of Change, John Parigger

Electronic Theses and Dissertations

There is a sharp increase in anxiety and depression symptoms in adolescence, and many forms of psychotherapy are shown to be effective. However, most research has examined average effects for manualized treatments that address multiple areas of functioning, which makes it difficult to determine how psychotherapy causes positive change. Process-based therapy postulates that all psychotherapies work through promoting adaptive biopsychosocial patterns of behavior (i.e., processes of change). Research has increasingly focused on the process-based therapy model, and there is a need for qualitative studies to incorporate lived experience into our understanding of change processes. The current study utilized the process-based …


Relational Reasoning Across Cultures: Consistency And Variation In South Korea, The United States, And China, Alexandra Carstensen, Minju Kim, Youngon Choi, Caren M. Walker Aug 2026

Relational Reasoning Across Cultures: Consistency And Variation In South Korea, The United States, And China, Alexandra Carstensen, Minju Kim, Youngon Choi, Caren M. Walker

Psychology Faculty Articles and Research

Abstract reasoning in early childhood is often described as following a “relational shift,” over which children become increasingly sensitive to relations. However, recent work has challenged the generality of this account, showing that children in the US and China follow distinct trajectories in a relational match-to-sample task. This difference aligns with multiple cultural and linguistic factors implicated in relational reasoning, where the US and China appear at opposite ends of a continuum, focusing on objects (US) versus relations (CN). This raises the possibility that differences in culture and language may shape variation in the development of abstract reasoning. Here, we …


Relationship Identification Between Triggers And Changes In The Brain And The Overall Human Electrophysiology During Migraines, Dominic Sandell, Jonah Dematto, Gianpiero Lara, Jasmine Rosales, Legacy Wilson, Zachary Young Aug 2026

Relationship Identification Between Triggers And Changes In The Brain And The Overall Human Electrophysiology During Migraines, Dominic Sandell, Jonah Dematto, Gianpiero Lara, Jasmine Rosales, Legacy Wilson, Zachary Young

Discovery Day - Daytona Beach

One of the most common neurological conditions in the world is migraines; nearly 1/4th of the working population suffers from this condition and exhibits a large variety of triggers. The current treatment method for migraine uses few different medications for all migraines, regardless of triggers. Our hypothesis is that there is a specific relationship between the triggers of migraines and the electrical changes in the brain during migraines. It is known that electrical activity in the brain occurs during migraines; it is unclear whether these changes differ across triggers. The study incorporates two different data collection methods: electrophysiological tests (Electroencephalogram …


Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv Jun 2026

Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv

MUSC Theses and Dissertations

Mu opioid receptor (MOR) agonists are recognized to disinhibit tonic dopamine (DA) in the ventral striatum (VS), contributing to opioid addiction and euphoria. However, MOR agonists can also inhibit non-drug reward-seeking, and disrupt conditioned responding to aversive stimuli, a phenomenon not readily explained by tonic DA disinhibition. We hypothesized that this effect could be due in part to disruption of phasic DA responses to conditioned stimuli (CS) which critically shape and maintain behaviors during naturalistic reward and aversive processing. Because MOR effects on CS-evoked phasic DA are largely unexamined, we conducted in vivo fiber photometric recordings in water-deprived male and …


Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese Jun 2026

Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese

Dissertations, Theses, and Capstone Projects

The ability to discriminate between cues predictive of threat vs. safety (fear acquisition) and subsequently update fear responding when contingencies change (fear extinction) is crucial to survival for all organisms. While these processes have been the subject of intense experimental scrutiny for several decades, most human fear learning studies have focused primarily on extinction learning and fear recovery processes, with less focus on fear acquisition itself. Indeed, researchers typically aim to minimize variability during fear acquisition in order to rule out differences in extinction being driven by variability during the initial learning phase. Thus, experimental protocols are often optimized to …

Impact Of Eating Disorder Type On General Population Perceptions Of Stigma And Likelihood Of Comorbidity, Gabri Notov, Grace Schroeder, Kaz Skelton, Kevin Summers, Sarah Huff May 2026

Impact Of Eating Disorder Type On General Population Perceptions Of Stigma And Likelihood Of Comorbidity, Gabri Notov, Grace Schroeder, Kaz Skelton, Kevin Summers, Sarah Huff

DU Undergraduate Research Journal Archive

Eating disorders carry a significant risk of mortality, necessitating further research. Previous work has examined how stigma influences treatment seeking in other mental health conditions, creating a potential area for improving disordered eating outcomes. Additionally, prior meta-analyses have discovered high comorbidity of other mental health diagnoses with disordered eating. Some work has attempted to examine the perception of comorbid mental health problems alongside eating disorders, but this construct has not been studied in depth within general populations. To date, no work has simultaneously examined stigmatization and knowledge of common mental health problems with disordered eating in this population. This study …


Navigating Burnout: The Role Of Workplace Support For Social Work Clinicians, Melanie Fulton May 2026

Navigating Burnout: The Role Of Workplace Support For Social Work Clinicians, Melanie Fulton

Journal of Global Awareness

The shortage of mental health workers is a growing concern in the United States, and social workers a substantial portion of employees who work with individuals with mental health concerns. This shortage stresses the importance of studying factors that impact burnout for mental health clinicians, particularly social work clinicians.

Behavioral Science Applications In Collegiate Athlete Nutrition And Sleep: A Scoping Review, Maryam Yuhas, Katherine M. Kidwell, Olivia Moskuna, Rajib Mandal, Jessica L. Garay

Nutrition - All Scholarship

Nutrition and sleep are key health behaviors supporting athletic performance. Collegiate athletes in the United States (U.S.) are at high risk of insufficient dietary intake and nightly sleep given the competing demands of elite sports and academics. Researchers have developed interventions to improve collegiate athletes’ sleep and nutrition, either individually or collectively. However, progress in understanding how best to create sustained behavior change in this population has been slow. This may be due to the lack of application of behavioral science principles such as lack of a guiding theory, effective strategies, and consideration of implementation contexts. This scoping review takes …

Feeding The Future: Prenatal Dietary Effects On Offspring Neurodevelopment, Emma Whatley May 2026

Feeding The Future: Prenatal Dietary Effects On Offspring Neurodevelopment, Emma Whatley

Senior Honors Theses

This study examined the effects of prenatal Western (WD) and Mediterranean (MD) diets on offspring metabolic, cognitive, and neurobiological outcomes in a preclinical mouse model. Working and long-term memory performance, dendritic morphology, and gene expression were assessed using behavioural tests (CAL, YMRM, WM) and Golgi-Cox analyses. Behavioural effects were minimal, with female MD offspring showing improved memory performance under standard conditions. Metabolic findings showed effects on body weight and blood glucose. Dendritic morphology was largely unchanged; however, subtle, sex-specific differences were observed. Differential gene expression between MD and WD suggests a role for future environmental stressors. Prenatal diet affects molecular …


The Influence Of Valence On Action Control: A Comparison Of Simon Effects In The Extrinsic Affective Simon Task (East) And The Spatial Simon Task, Yaara Aleissa May 2026

The Influence Of Valence On Action Control: A Comparison Of Simon Effects In The Extrinsic Affective Simon Task (East) And The Spatial Simon Task, Yaara Aleissa

College of Arts & Sciences Senior Theses

People adjust their thoughts and actions in response to a changing environment every day and emotions may influence these actions. Understanding how emotion impacts action control in situations where emotion is central to the action (task-relevant) compared to when it is present in the environment as distracting information (task-irrelevant) is essential. Currently it is unclear when emotion most significantly modulates action control. This study seeks to compare how valence (positive versus negative emotion) impacts action control performance when valence is task-relevant and task-irrelevant by using two modified versions of the Simon conflict task.

The Simon task is a paradigm to …

Schneider, Savannah E. Straub, Joe Parker, Lillianna P. Puppel, Aleece K. Al-Olimat, Allison M. Bach, Phillip R. Zoladz

ONU Student Research Colloquium

Single treatments with psychedelics produce rapid, long-lasting antidepressant effects. Psychedelics may also exert anxiolytic effects and be useful in treating more complex psychiatric conditions, such as PTSD. However, less is known about the impact of these agents on PTSD-related symptoms. Thus, we aimed to determine whether a single administration of psilocybin could reverse PTSD-like sequelae induced by stress-enhanced fear learning in rats. Sprague-Dawley rats were placed in Context A (circular, white conditioning box) and exposed to several uncontrollable footshocks (Stress) or no footshocks (No Stress). The next day, the rats were placed in Context B (square conditioning box with clear …

Psilocybin And The Related Tryptamine, Norbaeocystin, Exert Acute Anxiogenic Effects That Depend On Sex, Marisa J. Savini, Kylie M. King, Noelle M. Molnar, Evelynn J. Schneider, Savannah E. Straub, Joe Parker, Lillianna P. Puppel, Aleece K. Al-Olimat, Allison M. Bach, Andrew Jones, Phillip R. Zoladz

ONU Student Research Colloquium

Single treatments with psychedelics have demonstrated rapid, long-lasting antidepressant effects. However, psychedelics often produce unfavorable psychoactive effects that could worsen existing psychological distress. Thus, we compared the effects of psilocybin and the related tryptamine, norbaeocystin, on anxiety-like behavior in male and female rats. In Experiment 1, rats were treated with 1 mg/kg psilocybin (PSIL), 1 mg/kg norbaeocystin (NOR), or vehicle 30 min before a 5-min trial on an elevated plus maze (EPM) or in an open field test (OFT). On the EPM, PSIL led to decreased open arm time and fewer arm entries in males and females. NOR led to …


Out-Of-Pocket Costs And Antihypertensive Medication Use Among Veterans: A Natural Experiment, Alexander R. Zheutlin, Alexander Chaitoff, Daniel Addo, Joshua A. Jacobs, Catherine G. Derington, Eric L. Stulberg, Peter A. Glynn, Bernardo Modenesi, Jordana B. Cohen, Adam P. Bress Apr 2026

Out-Of-Pocket Costs And Antihypertensive Medication Use Among Veterans: A Natural Experiment, Alexander R. Zheutlin, Alexander Chaitoff, Daniel Addo, Joshua A. Jacobs, Catherine G. Derington, Eric L. Stulberg, Peter A. Glynn, Bernardo Modenesi, Jordana B. Cohen, Adam P. Bress

Department of Neurology Faculty Papers

BACKGROUND: Blood pressure (BP) control remains suboptimal in the United States despite available low-cost antihypertensive medications. Even small out-of-pocket medication costs may contribute to adherence. We determined whether $0 versus >$0 out-of-pocket costs for antihypertensive medications is associated with differences in adherence, discontinuation, BP control, and cardiovascular outcomes.

METHODS: We included veterans with newly diagnosed hypertension who initiated antihypertensive medication in the Veterans Health Administration from 2004 to 2022. A fuzzy regression discontinuity design with 2-stage residual inclusion leveraged differences in medication copay policy at a 50% service-connected disability threshold (≥50% service-connected disability: $0 out-of-pocket cost versus < 50%: $8 monthly cost). Outcomes included 1-year medication nonadherence (proportion of days covered < 80%), 1-year medication discontinuation (no medication in the final 90 days of the study year), 1-year BP control (systolic BP/diastolic BP < 140/90 mm Hg and < 130/80 mm Hg) and cardiovascular disease events (myocardial infarction, coronary revascularization, peripheral artery disease, or stroke).

RESULTS: Among 417 …

Baltic Journal of Health and Physical Activity

Background/Objectives: Impulsivity is a key transdiagnostic trait linked to dysregulated reward processing in both behavioral and substance-related addictions, as recognized in DSM-5. Dopaminergic genes, including DRD2, may modulate individual differences in impulsivity, particularly under conditions of increased addiction vulnerability. This study examined whether the DRD2 Exon 8 rs6276 polymorphism predicts impulsivity levels in men with mixed addictive behaviors compared with healthy controls. Methods: A total of 328 males (128 with mixed behavioral and substance addictions and 200 controls) were assessed. Diagnoses were confirmed using the MINI interview, and impulsivity was measured with the Barratt Impulsiveness Scale (BIS-11). Genotyping of …
