Evaluating Spect Neuroimaging In Psychiatric Diagnosis: A Critical Review And Proposed Randomized Controlled Study, Kiley Carter

Senior Honors Theses

Mental illness affects a substantial proportion of adults in the United States, yet psychiatric diagnosis remains subject to diagnostic variability. Single-photon emission computed tomography (SPECT) is a neuroimaging technique that measures cerebral blood flow and has been proposed as an adjunctive tool for psychiatric evaluation. Existing literature reports group-level perfusion patterns associated with certain psychiatric conditions, suggesting potential utility in diagnosing complex or treatment-resistant cases. However, critics of SPECT emphasize the absence of randomized controlled data demonstrating improved patient outcomes. To address this gap, a prospective randomized controlled trial comparing standard psychiatric care with SPECT-guided evaluation is proposed. The proposed …

Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson’S Disease, Brock Renicks

Poster Presentations

Around 40% of people with Parkinson’s Disease experience depression and anxiety (Zhao et al, 2025). Depression and Anxiety have been said to be localized to the dorsolateral prefrontal cortex (Brunoni et al, 2016). Transcranial Direct current stimulation (tDCS) has been shown to modulate depression and anxiety by targeting the dorsolateral prefrontal cortex (Sreeraj et al, 2023). It is beneficial due to its cost, portability, and simplicity of use. Thus we will be assessing the efficacy of tDCS in reducing depression and anxiety in individuals with Parkinson’s Disease.

Fear Of Crime, Intolerance Of Uncertainty, And Trait Worry: A Mediation Model Of Perceived Risk And Victimization Concerns, Nicholai N. Chasseau

Theses and Dissertations

This study examined psychological vulnerability and fear of crime in 538 adults from Trinidad and Tobago. Perceived risk was the strongest predictor of fear, while prospective intolerance of uncertainty predicted fear directly. Mediation was supported among Afro-Trinidadians but not Indo-Trinidadians, suggesting sociocultural differences in cognitive pathways linking vulnerability to fear.

When A Friend Dies Young: Experiences Of Young People After The Traumatic/Sudden Death Of A Friend/Peer, Summer Langva

Celebrating Scholarship and Creativity Day (2018-)

The sudden or traumatic death of a peer during adolescence or young adulthood is a common yet understudied form of bereavement despite the developmental importance of peer relationships during this life stage. The present study examined the long-term psychological impact of peer loss by investigating prolonged grief symptoms, perceived social support, coping strategies, and posttraumatic growth among adults who experienced the sudden or traumatic death of a peer between the ages of 12 and 25. Participants (N = 31) completed an anonymous online survey consisting of standardized measures of prolonged grief, perceived social support, coping strategies, and posttraumatic growth, along …

Impostor Thoughts At Work: Examining The Relationship Between Impostor Thoughts, Employee Well-Being, And Coworker Support, Nikitha Sara Mohan

Theses, Dissertations and Culminating Projects

Most individuals experience impostor thoughts; however, limited construct clarity has hindered efforts to effectively examine their relationship with employee outcomes (Gullifor et al., 2021). To address this limitation, the present study adopts a sociocognitive perspective, conceptualizing impostor thoughts as beliefs that others overestimate one’s competence at work (Clance & Imes, 1978; Tewfik, 2022). Specifically, this research investigates workplace impostor thoughts and their associations with indicators of employee well-being, including job-related negative affect, burnout, physical symptoms, and perceived self-competence. Additionally, the study examines coworker support as a potential moderating factor in these relationships. A mixed-methods approach was employed. Quantitative data were …

Theory Of Mind And Emotion Recognition In Down Syndrome: A Comparative Developmental Trajectory Approach, Stephanie L. Grinshpun

Theses, Dissertations and Culminating Projects

Delays and impairments in social functioning are common in Down syndrome (DS), creating significant challenges for these individuals as they navigate social environments and relationships. Two fundamental components of social cognition and functioning are Theory of Mind (ToM), comprised of cognitive and affective ToM, and emotion recognition. While previous research has documented broad deficits within ToM and emotion recognition in DS, the current body of work does not provide a comprehensive account of how these two abilities develop, interrelate, or influence social functioning in this population. The current study investigated ToM and emotion recognition in a sample of 24 participants …

The Moral Influences On Non-Denominational Christian Students’ College Major Decision And Future Career Outlook, Makayla Frame

Honors Projects

This is an undergraduate research project for the Honors College. A qualitative research project in the form of case studies was conducted on the influence of Non-Denominational Christian morals and values on how college students decide college major and future career. Non-Denomination students in particular were chosen for this study because of the recent rise in popularity of the Non-Denominational belief in the US, especially among young adults.

The study outlines previous research on the Christian religion, the history of Non-Denominationality, and how typical college students decide their major. The conclusions of the study are that Non-Denominational Christian college students …

Limerence, Social Media, And The Reinforcement Of Romantic Obsessions Across Online Contexts, Lily Lawson

Honors Projects

This project examines limerence from both a psychological and sociological perspective. The psychological component aimed to investigates whether higher limerent scores predict greater engagement in social media monitoring behaviors related to a romantic interest, and whether these monitoring behaviors are associated with increased interpretation of ambiguous social cues-failure to obtain IRB approval resulted in limitations in completing the study. The sociological component uses qualitative observational methods to examine how two Reddit communities,  r/NevilleGoddard and r/ShiftingRealities,  reinforce limerent and parasocial romantic behaviors. Findings from the qualitative analysis reveal patterns of emotional attachment, ritualized obsession, perceived reciprocation, self-insert fantasy, and escapism across …

Methods: A cross-sectional, web-based survey was conducted across 22 universities in four SSA countries using convenience sampling. A total of 1189 university staff and students, including parents and non-parents, participated. Mental health outcomes were assessed using the Depression, Anxiety, and Stress Scales (DASS-21). Multinomial logistic regression models were used to examine associations between parenthood status and mental health outcomes after adjusting for sociodemographic and contextual factors. Results: Participants with children had lower odds of moderate depression (adjusted …

The Rodent Electronic Nicotine Delivery System (Rends): Effects Of Age On Self-Administration Of Inhaled Nicotine In Female Rats, Daniel Santos Da Silva

All Graduate Theses and Dissertations, Fall 2023 to Present

Smoking tobacco is the leading avoidable cause of death and drives many health problems. Nicotine, the main chemical in tobacco products, keeps people using it. This study used the Rat Electronic Nicotine Delivery System (RENDS), an inexpensive and freely shared, to examine e-cigarette use in adolescent and adult female rats by exploring four phases of nicotine delivered and not delivered to understand use patterns among ages. Our study found that both adolescent and adult female rats chose to inhale nicotine when given the opportunity, showing drug-seeking behavior. Overall, nicotine use was similar between ages. These results could help inform therapies, …

Sex Differences In How Celebrity Crushes Bolster Self-Perceived Mate Value, Madyson M. King

Psychological Science Undergraduate Honors Theses

Previous research indicates that parasocial relationships provide surrogate connections for individuals to where they offer various psychological benefits. Some benefits include self-esteem and improved body image, which may be connected by such relationships facilitating attainment of one's ideal self. Given this benefit of social surrogacy, it could be possible that a vicarious romantic connection with a parasocial figure may similarly bolster one's mate value if that relationship were to move an individual closer to a personal ideal. We predicted that engagement with a celebrity crush would be associated with a heightened mate value. A community sample of men and women …

Negation And The Backfire Effect, Caden Fowler

Psychological Science Undergraduate Honors Theses

Quick! Do not think of a polar bear. Did you think of a white bear? As Russian author Fyodor Dostoevsky wrote in his 1863 essay “Winter Notes on Summer Impressions,” “[when tasked to not think of a polar bear] you will see that the cursed thing will come to mind every minute.” The consequence of negation without context (i.e., unlicensed negation; Levine & Hagaman, 2008) is what has come to be referred to as the “backfire effect,” a phenomenon where correcting misinformation strengthens belief in that information rather diminishing it (Ecker, et al., 2020). Fake news and misinformation in …

The Effects Of Cannabidiol (Cbd) On The Social, Cognitive, And Physical Facets Of Anxiety Sensitivity, Ezri Rathbun

Psychological Science Undergraduate Honors Theses

The current study investigated how repeated administration of 300mg of cannabidiol (CBD), when compared to a placebo, affects the social, cognitive, and physical facets of anxiety sensitivity (AS), a characteristic that reflects fear of the consequences of anxious arousal. Prior work suggests CBD may have anxiolytic effects that may be specific to the social aspects of anxiety. Thus, it was hypothesized that, that, relative to placebo, CBD would reduce self-reported AS-social concerns, but not AS-cognitive or AS-physical concerns, compared to baseline. Participants (N= 79; 52 women; M_age = 22.06) with elevated perceived stress were randomly assigned to 14 …

Amusement In The Absence Of Empathy: Psychopathy In Relation To The Use And Appreciation Of Dark Humor, Jolie A. Brewer

Psychological Science Undergraduate Honors Theses

Although humor functions to foster integration between individuals, not all types of humor are equally appreciated by everyone. Some forms of humor are controversial, which limits their appreciation to specific contexts and potentially to specific people. One form of humor that may meet this definition is dark humor. Production of dark humor could imply that the humorist is disinterested in conventional social situations while similarly conveying an exploitative intention. Given that individuals who exhibit heightened levels of psychopathic personality traits also have a relative disinterest in adhering to social norms, it could be possible that psychopathy is associated with a …

What Are The Roles Of Vocabulary And Working Memory In Metaphor Comprehension?, Claire Simpson

Psychological Science Undergraduate Honors Theses

One of the most notable factors that influence sentence comprehension is the presence of metaphors (e.g., Inhoff, Lima, & Carroll, 1984). The metaphor interference effect (MIE) is a very interesting result of metaphor comprehension. It is a well-known linguistic effect (e.g., Al- Azary et al., 2021; Glucksberg et al, 1982) that can result in participants taking longer to determine that a metaphoric statement is false compared to other non-metaphoric literally false statements. The present study investigated the impact that vocabulary knowledge, working memory capacity, and memory load have on the metaphor interference effect. We predicted that each of these characteristics …

Avoiding Pathogens Or Avoiding People? Pathogen Avoidance, Pathogen-Specific Stereotypes, And Intergroup Bias Toward South Asians, Aashvi Dahiya

Psychological Science Undergraduate Honors Theses

People are motivated to avoid pathogens because infection poses serious risks (e.g., illness, death). Pathogen avoidance often relies on indirect cues and stereotypes—like appearance or group membership—to identify potential pathogen threats. A large body of literature has linked pathogen avoidance to intergroup bias, but recent work suggests that this link may vary across social groups. In particular, pathogen avoidance may be more strongly associated with intergroup bias toward groups specifically linked to pathogen-specific stereotypes. The present study examined whether pathogen-specific stereotype endorsement moderates the relationship between pathogen avoidance and intergroup bias toward South Asians. A sample of 684 participants completed …

A Vicious Cycle: The Interplay Between Anxiety, Perfectionism, And Indecision, Kaelyn G. Moran

Psychological Science Undergraduate Honors Theses

Chronic indecisiveness is a pervasive issue that can negatively impact academic, occupational, and psychological functioning. Although prior research has identified anxiety and perfectionism as relevant correlates of indecisiveness, less is known about how these factors uniquely and jointly contribute to decision-making difficulties. The present study examined the relationships between trait anxiety, multidimensional perfectionism, and indecisiveness in a sample of 199 undergraduate students at the University of Arkansas. Participants completed self-report measures assessing anxiety (STICSA), perfectionism (Frost Multidimensional Perfectionism Scale), and indecisiveness (Revised Indecisiveness Scale). Zero-order correlations and multiple regression analyses were conducted to evaluate both overall and dimension-specific effects. Results …

The Effect Of Self-Disclosure To Dogs On Stress, Coping, And Emotional Well-Being, Lilian Crawford

Psychological Science Undergraduate Honors Theses

Self-disclosure has been defined as the voluntary sharing of personal thoughts and experiences with another individual, and in recent years, it has been associated with improvements in psychological and physiological well-being. Recent research into animal-assisted therapy has also demonstrated the emotional benefits of interacting with dogs. However, the current research has not yet explored how the specific act of self-disclosure to dogs affects emotional well-being. The present study explored the effects of self-disclosure to dogs on stress, ability to cope, and emotional well-being. Participants (N = 113) included dog owners who were randomly assigned to one of three conditions: self-disclosure …

The Relationship Between Media Use, Identity, And Attitudes Towards Women, Kelly A. Summers

Psychological Science Undergraduate Honors Theses

Pornography’s popularity among college men is widespread, with degrading content being common in top-selling pornography (Bridges et al., 2010; Foubert et al., 2011). Research has shown higher consumption of degrading pornography is associated with more negative attitudes towards women, greater acceptance of rape culture, more sexist beliefs, and greater likelihood of engaging in aggressive and dominant behavior during physical intimacy (Bridges et al., 2023). “Incels” (a term meaning involuntarily celibate) are individuals who have not yet had a sexual debut despite an interest. Relatively little research exists on this population, but the little that has been conducted suggests incels have …

Grace Under Pressure: An Analysis Of School Administrator Personal And Professional Stress And Self-Efficacy, Andrew Mcdaniel

All-Inclusive List of Electronic Theses and Dissertations

Indiana public school administrators are one of the most important factors for a school’s academic success. If those administrators are effective, they can help maintain an excellent school’s academic success or perhaps even turnaround a failing school. Without a doubt, their performance is critical for a school’s success. If they have confidence in their ability to help create positive outcomes, their school can achieve great things. Unfortunately, assistant principals and principals are facing significant challenges, not only from schools, but also at home. How do these personal and professional stressors affect their sense of self-efficacy? The purpose of this study …

The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi

Dissertations

Framing effects can shape perceptions, beliefs and behavior, particularly in prosocial contexts. The current study examined how language framing (social justice, social activism, volunteerism) and moral values influence interest in prosocial engagement across low- and high-cost helping scenarios. Participants (N = 219) were randomly assigned to one of three framing conditions and reported willingness to help in both low- and high-cost situations. They also completed the Moral Foundations Questionnaire. Replicating prior work (Olagbegi and colleagues, 2024), participants were more willing to engage in low- than high-cost helping. Across conditions, social justice framing elicited the greatest willingness to help. Higher fairness …

Raising Regulated Moms: Reducing Reactive Parenting Responses, Victoria J. Perez

Capstone Projects and Master's Theses

Many parents and caregivers lack access to information and support that accurately relates effective parenting styles, without this knowledge caregivers and parents may unintentionally rely on reactive responses that end up escalating conflict with their child rather than resolving it. When parents respond to their child's big emotions without effective tools to first regulate themselves, they risk contributing to higher stress levels, emotional withdrawal, and behavioral dysregulation in their children. Research consistently demonstrates that when parents are given the tools to successfully incorporate self-regulation skills and evidence-based approaches to guide children through difficult emotions, both the child and the parent …

Detection Of Changes In Short Narratives, Presley Priddy

Psychological Science Undergraduate Honors Theses

Narrativity and object association have been extensively researched in the past to determine how changes in a text impact reader interpretation. In this research, we attempted to establish a relationship between the relation of an object to a character situated in a particular narrative context and the detection of inconsistencies presented in the given story. Participants read texts that either associated or dissociated an object with a character, within a high or low-narrative context. Reading times were measured on critical sentences that were inconsistent with the placement of previously dissociated objects. When presented with object inconsistencies in highly narrative stories, …

Navigating New Environments: Acculturative Stress And Substance Use Among International Vs Domestic Students From Latino/A Backgrounds, Madelyn R. Null

Psychological Science Undergraduate Honors Theses

College students can experience a range of cultural and social pressures that could relate to their alcohol and cannabis use. Latino/a international students may face unique challenges as they adjust to campus environments in the United States (U.S.), yet little research has compared their substance use patterns to those of Latino/a domestic students. Therefore, the present study aims to examine whether: (a) Latino/a international and domestic students differ in their alcohol use, (b)they differ in their cannabis use, and (c) acculturative stress moderates the relationship between international student status and these substance use behaviors. Latino/a undergraduates (n=440; Mage=20.55; female=71%; international=21%) …

Depression Symptoms Are Associated With Less Positively Biased Self-Ratings Of Attentional Control, Anna E. Morgan

Psychological Science Undergraduate Honors Theses

Deficits in the ability to flexibly direct, sustain, and shift attention, known as attentional control, have been linked to anxiety and depression. Attentional control supports engaging with goal-relevant stimuli while effectively disengaging from irrelevant or emotionally distracting stimuli. Thus, it is crucial in cognitive processes and emotional responses. Common measures of attentional control include behavioral tasks and self-report measures. However, behavioral and self-report measures are weakly correlated, suggesting that individuals generally are not good at perceiving their attentional control abilities. This mismatch between measures could be related to anxiety and depression symptoms. The goal of my project was to examine …

Unveiling Embodied White Supremacy: Therapists’ Experiences And Its Imprint On Therapeutic Relationships In Dance/Movement Therapy, Melody E. Gamba

Counseling and Psychology Dissertations

This qualitative, arts-informed research study explored how White-identifying dance/movement therapists experience and articulate their awareness of embodied White supremacy within therapeutic relationships. Grounded in critical race theory, relational-cultural theory, and embodied critical transformation theory, the study addressed a gap in dance/movement therapy literature concerning how White supremacy is not only cognitively understood, but also somatically felt, relationally enacted, and professionally navigated. The purpose of the study was to understand how White-identifying dance/movement therapists perceive, kinesthetically experience, and make meaning of embodied White supremacy in therapeutic practice, and to explore how these embodied experiences influence therapeutic presence, attunement, and the potential …

Overwhelmed By Competing Priorities: Exploring Women’S Motivational Conflict Across The Menstrual Cycle, Arial S. Bloshinsky

Graduate Theses and Dissertations

This study examined whether the biological context of the menstrual cycle predicted overwhelming feelings due to competing bonding and achievement motivations (i.e., motivational conflict). Building on the motivational shift hypothesis, it was predicted that the luteal phase, characterized by elevated progesterone and heightened bonding motivation, would be associated with more overwhelming feelings from motivational conflict. To assess potential changes across the menstrual cycle, a within-person design was used where women reported their overwhelming feelings daily. Primary analyses did not support the hypothesis. Overwhelming feelings from motivational conflict did not differ across cycle phases. However, the expected mid-cycle peak in sexual …

Self-Directed Violence In Athletes, Adela Vavrinova

Graduate Theses and Dissertations

Self-directed violence (SDV) in athletes comprises a spectrum of behaviors, including non-suicidal self-injury (NSSI), suicidality, and self-harming behaviors that can be embed- ded within sport contexts. Competitive sport environments may intensify psychological vulnerability through factors such as performance demands, body-image pressures, injury and rehabilitation stress, and norms that discourage help-seeking. This thesis synthesizes existing literature on SDV among athletes with the aim of clarifying how SDV is concep- tualized and measured, summarizing what is known about prevalence patterns, functions, and contextual risk factors, and identifying prevention and intervention strategies relevant to athlete systems. The reviewed evidence suggests the SDV literature …

Understanding The Effects Of Adventure Therapy On Inner City Youths' Sense Of Relatedness, Nicolas Bellegarde

Graduate Theses and Dissertations

Adventure therapy is a creative, transtheoretical group-based model of counseling that utilizes kinesthetic activities coupled with metaphors and processing modalities, alongside experiences outdoors, to facilitate insight and motivate healthy communication between group members. Through intentional sequencing and guidance of activities, facilitators aim to improve participants' communication skills, group engagement, and ability to tolerate discomfort and risk while strategically solving problems. In addition, the integration of nature and the outdoors has been demonstrated to improve mental health and well-being, generating a sense of connectedness to the environment and to the group. Adolescence is a time of rapid developmental change characterized by …

Effects Of Social Sport Settings And Belonging On Female Athlete Mental Health Stress, Abby Caudill

Undergraduate Theses

Mental health concerns among collegiate athletes have become an increasingly important issue, particularly for female athletes who face unique social and performance-related pressures. Understanding the factors that contribute to or protect against mental health stress is critical for improving athlete well-being. The purpose of this study was to examine whether sport type, team belonging, self-stigma, and athletic identity were associated with mental health stress among female collegiate athletes. Participants included 57 undergraduate female athletes from a small private university who completed self-report survey measuring team belonging, self-stigma, athletic identity, and mental health stress. Bivariate correlation results indicated that higher self-stigma …
