Acute And Chronic Oral Administration Of Cannabidiol-Dominant Cannabis Products: Sex- And Formulation-Dependent Effects On Anxiety-Like Behavioral Patterns In Rats, Carlos R. Maestas-Olguin

Psychology ETDs

Interest in the anxiolytic-like effects of cannabidiol (CBD), the non-intoxicating phytocannabinoid found within the genus, Cannabis, has grown significantly in recent years. However, preclinical investigations of CBD’s anxiolytic potential often elect to forgo translationally relevant models that maximize external validity in favor of greater internal and mechanistic validity. As a result, the effects of relatively low dose (< 3mg/kg) oral CBD administration on anxiety-like behaviors are not yet fully characterized. The present studies examined the impact of two orally delivered CBD-dominant cannabis products – a “full-spectrum” formulation derived from the whole plant and a CBD isolate derived from the same chemovar – on innate defensive behaviors exhibited by adult male and female rats in various tests of anxiety. Results indicated that acute and chronic low dose oral CBD administration attenuated anxiety-like behavior in rats, regardless of sex or formulation. These findings extend the growing corpus of literature describing anxiolytic-like effects of CBD.

Examining Associations Between Socioecological Factors And Addiction Cycle Domains In Separate Community And Treatment- Seeking Samples, Kara Link

Psychology ETDs

The Addictions Neuroclinical Assessment (ANA) is a multimodal clinical assessment framework designed to capture the heterogeneity of addictive disorders and inform personalized treatment. The ANA is grounded in three neurofunctional domains aligned with the Koob and LeMoal addiction cycle stages: incentive salience (IS; binge/intoxication), negative emotionality (NE; withdrawal/negative affect), and executive function (EF; preoccupation/anticipation). In addition to these primary domains, the ANA also proposes ancillary assessment domains thought to be related to these neurofunctional domains. However, the ANA developers do not provide a rationale for including these ancillary measures in the framework nor hypothesize about their relevance to the ANA …

A Characterization Of Fat Acceptance Across Identities In A College Sample, Brynn Liabraaten

Psychology ETDs

Weight stigma is a class of discrimination in which those who are of higher weight face biases and discrimination. This can lead to worse outcomes ranging from poor mental health to societal barriers. Fat acceptance is the idea that all people, regardless of weight, deserve respect and equal treatment. The study of fat acceptance is in its infancy in the field of psychology, and there is little research addressing what kinds of people may be more or less fat accepting. The present study utilized a college sample to create a characterization of which intersecting identities and characteristics may correlate with …

Predictors Of Opposite-Sex Antipathy, Mikayla R. Poe

Psychology ETDs

Evolutionary pressures have shaped men’s and women’s motivations to cooperate and compete with one another. Sexual conflict is generated in natural conditions but may be exacerbated by features of the modern world. The current study recruited participants from Prolific to respond to a Qualtrics survey (n = 812) to investigate the correlates of opposite-sex distrust/antipathy using the newly developed Opposite Sex Antipathy (OSA) scale, which is the first of its kind to allow cross-sex comparisons. Men and women’s antipathy for each other was predicted by perceptions that the opposite sex was of lower value to society, more harmful experiences …

Tiktok And The Brain: Neuropsychological Correlates Of Short-Form Video Consumption, Caty Enders

Psychology ETDs

Short-form video platforms like TikTok have quickly become the fastest growing segment of social media, thanks to powerful algorithms serving up personalized content driven by large quantities of user data. This study investigates the neuropsychological correlates of digital media use, with a particular focus on TikTok and smartphone screen time among young adults. Combining correlational analyses and an experimental design (n = 49; n = 44 included in final sample), we examined the relationship between digital media use and cognitive and emotional functioning across multiple domains. Objective measures of digital media consumption (daily average screen time and time on TikTok) …

Identity, Sexuality, And Gender: Perspectives From Self-Identified Sexually Fluid People, Mattilyn Wiseman

Psychology ETDs

Research on sexual fluidity has relied on categorical, gender-based measurement frameworks that prioritize quantifying change over exploring the lived experience of sexually fluid people. This study employed Interpretive Phenomenological Analysis (IPA) to qualitatively and ideographically explore how self-identified sexually fluid people made sense of their own sexual identity, gender (more broadly), and attraction as it relates or does not relate to gender. Three participants completed structured interviews with open-ended questions. Participants unanimously made sense of identity as a self-constructed journey and tied to their social realities. Participants’ lived experiences of their own gender identities informed their sense-making of gender more …

Clarifying The Illusory Truth Effect: The Role Of Truth Status And Source Memory, Kamille Koger

Psychology ETDs

The present study investigated whether repetition increases perceived truth even for information explicitly known to be false and how repetition effects interact with source memory. Participants (N = 102) completed two sessions (exposure and test) one week apart. During exposure, they rated the truth of trivia statements presented three times each. Half were explicitly labeled as "true" or "false" (known condition) and half were unlabeled (ambiguous condition). In the test phase, participants judged the truth of all previously seen statements and an equal number of new statements, followed by source memory judgments. Results showed a classic illusory truth effect (ITE) …

From Body Positivity To Body Power: How Music Therapy And Body Liberation Intersect To Address Body Oppression In The Therapeutic Space–A Literature Review, Katherine M. Perkoski

Expressive Therapies Theses

With the rise of overt fascism, anti–fat bias, anti–intellectualism, anti–multiculturalism, anti–diversity, equity, and inclusion, and the persistence of white, capitalist, cisheteropatriarchy narratives around bodies, music therapists need to recognize how client and therapist bodies show up in practice. In this critical literature review, bodies will be sociopolitically and culturally contextualized, and the intersections of music therapy, body liberation, and body power will be discussed. Music therapists need to address the body oppression faced by sociopolitical identities such as race, gender, disability, age, body size, sexuality, neurodiversity, class, ethnicity, nationality, housing status, and immigration status. The music therapy field needs to …

Re-Painting Motherhood: A Community-Based Expressive Arts Project Exploring Motherhood’S Myths, Realities, And Hopes Through A Narrative Therapy Lens, Lauren Grignaffini-Morris

Expressive Therapies Theses

This thesis examines how socially constructed ideals of motherhood shape maternal identity, distress, and isolation, and explores the potential of addressing these experiences through a community-based expressive arts project. Drawing on motherhood studies, expressive arts therapy, and narrative therapy, the project highlights the potential benefits of utilizing expressive arts in a community setting to ease the tension between romanticized cultural narratives and the lived realities of mothers. Conducted with a support group for mothers in rural Vermont, the project used visual art, movement, creative writing, and collaborative mixed-media painting to examine problem-saturated motherhood stories, connect through embodied experience, and explore …

Arts-Based Violence Prevention For Youth: A Literature Review, Amber Lynn Isaac

Expressive Therapies Theses

This narrative literature review examines arts-based approaches to violence prevention and trauma-related support among school-aged children and adolescents in school and community settings. Violence is conceptualized as both interpersonal and structural, encompassing physical, emotional, relational, and systemic harms that arise through unequal access to safety, opportunity, and resources. The review then explores how these conditions increase vulnerability to trauma exposure, particularly among youth in marginalized and underserved communities, and considers the psychological impacts of violence on youth development. Centering the resilience of children and adolescents through relational strengths, adaptive coping strategies, and creative capacities, this review then examines the benefits …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Doctor of Ministry Projects and Theses

To address the growing and widespread epidemic of social isolation and loneliness, with special focus on Black churches, this dissertation developed a program with the following areas of application: 1) how healthcare trained chaplains can coordinate with churches to positively impact individuals identified as lonely and socially isolated with better social and physical health, 2) how principles of chaplaincy and pastoral care can mitigate and intervene competently when such people are identified, and 3) how the project’s model can be organized, taught, and incorporated into existing arenas of church ministry.

The purpose of the project was to create a ministry …

The Motivation Tapes: Employee Narratives Of Leadership That Matters, Jessica Gray

Masters Theses, 2020-current

This qualitative phenomenological study explored how employees describe their lived experiences at work. The purpose of the research was to understand the relational, emotional, and developmental dimensions that shape employees’ day-to-day workplace realities and the meanings they assign to those experiences. Four participants from diverse occupational backgrounds were interviewed using semi-structured protocols designed to elicit rich, descriptive accounts of their work environments, relationships, and sense-making processes. The findings reveal that participants shared experiences of supportive and hands-on leadership, opportunities for autonomy and ownership, and moments of connection, meaning, and long-term growth. Participants also described disruptions to these experiences. The implications …

Examining The Glat As A Measure Of Ai Literacy, Hunter R. Castleton

Masters Theses, 2020-current

The current study examined the Generative AI Literacy Assessment Test (GLAT) as a promising test of AI literacy due to its content, which is grounded in relevant AI literacy theory, and its design as a cognitive measure of AI literacy. To examine the GLAT, data were collected from a sample of 543 graduating seniors at James Madison University (JMU) who took the GLAT as part of a longer series of tests. Their responses were first analyzed to assess the test’s item characteristics and internal structure. Following this initial analysis, a final item set was established to ensure that low-quality items …

Using Behavior Skills Training To Shape Paraprofessional Fidelity And Reduce Student Latency To Begin Non-Preferred Academic Tasks During Transitions, Maria C. Cole

Masters Theses, 2020-current

The purpose of this study was to investigate the use of behavior skills training (BST) to improve a paraprofessional’s implementation fidelity of evidence-based strategies targeting transition-related behaviors in a student with autism spectrum disorder (ASD). A changing criterion design was used to evaluate whether a functional relation between BST and the implementation of a task-analyzed transition protocol existed. The staff participant was assessed across baseline, three phases of BST intervention, and a mini-reversal phase included to further assess experimental control. Student data were collected tangentially in further evaluating experimental control. The paraprofessional participant demonstrated improving implementation fidelity trends within and …

Variations In Moral Decision Making: In Morally Ambiguous Scenarios, Riley N. Eaton, Victoria Kempton, Edward Lansing, Troy R. Welker

Aurora

People are tasked with making decisions that often come with consequences, whether it be for someone else or themselves. Due to this, there is an ambiguity in understanding what is “right” and “wrong” in a given scenario. However, limited research has examined how interpersonal relationships and intensity of the punishment may affect this decision-making process. This study examines the effect of interpersonal closeness and punishment intensity on moral decision-making, defined in terms of fairness and empathy. Participants (N = 54) from a midwestern university were randomly assigned to one of three interpersonal closeness conditions (close friend vs. close friend, close …

Counseling and Psychology Dissertations

Compassion Fatigue (CF) is a state of emotional and physical exhaustion resulting from prolonged exposure to stressful or traumatic experiences, specifically among healthcare workers, and it negatively impacts their ability to provide care to their patients and perform their jobs effectively (Singh et al., 2020). The purpose of this qualitative study is to explore the lived experiences of compassion fatigue in mental health clinicians who previously worked in in-patient psychiatric hospitals and their subsequent resignations. This phenomenological research explored participants' understanding and descriptions of their CF experiences in their roles within psychiatric hospitals and how CF contributed to their leaving …

Proximal Stress And Gender Identity: The Role Of Internalized Transphobia In Future Expectations, Maribelle Almonacy

Student Theses and Dissertations

Transgender and non-conforming (TGNC) youth and young adults are more likely to experience symptoms of posttraumatic stress due to identity-specific abuse. Studies on the impact of trauma on negative expectations in high-risk youth show a high association between pessimism, nihilism, and instability. Internalized transphobia, similarly, is correlated with negative mental health outcomes, such as depression and anxiety, and the internalization of social messages and discrimination. These studies are not specific to the experiences of gender minorities and do not explore the intersections of internalized stressors or trauma in young adults. To address this gap in literature, this study sought to …

Exploring Ai-Driven Scaffolding For Critical Questioning In Argument Evaluation, Ebenezer A. Belete

UNLV Theses, Dissertations, Professional Papers, and Capstones

The fast-paced changes caused by generative AI (GenAI) innovations call for exploring the potential benefits of GenAI in empowering 21st-century pedagogical strategies. Previous studies in the field of argumentation have shown how students can benefit from using critical questions. However, scaffolding argument evaluation through custom GenAI using critical questions has not been systematically investigated. This study involved two components: (1) designing and determining the usability of a GPT-powered conversational assistant (CQMAA Conversational Assistant) and (2) testing its impact on participants' efficacy for argument evaluation and their acceptance of GenAI as a learning tool through a pretest–posttest experiment. A convergent mixed-methods …

Self-censorship, empowered resistance, and solidarity are critical yet understudied phenomena that shape the lived experiences of college students from racially marginalized communities. The present research comprises three studies examining the interconnected roles of these constructs in the psychosocial well-being and collective action of racially marginalized college students in the United States, specifically in the context of students’ activism behaviors during the 2023 and ongoing genocide in Gaza. Chapter 2 will present findings from an online mixed-methods study that examines college students’ self-censorship and psychological distress factors that support or hinder open discussion during the ongoing genocide in Gaza. Results suggest …

Perception Of Emotions In Autism With Controlled Elicitation, Rachel E. Dewald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on emotion recognition in autism has traditionally relied on stimuli developed and validated exclusively with allistic populations. Whether these stimuli function equivalently for autistic individuals remains unclear, limiting the field’s ability to draw conclusions about cross-neurotype differences in emotional processing. Grounded in double empathy theory and cross-cultural research demonstrating in-group advantages in emotion recognition, this thesis investigated whether the Database of Emotional Videos from Ottawa (DEVO), a dynamic emotional elicitation database validated with allistic participants, elicits comparable emotional responses in autistic individuals. Participants (N = 116) viewed DEVO video clips and rated their emotional responses using the Multidimensional Visual …

Functional Domains’ Ability To Predict Outcomes In Comparison To Absenteeism In A National Sample Of School Age Children, Randolph Dupont

UNLV Theses, Dissertations, Professional Papers, and Capstones

School absenteeism poses a critical challenge for educators, clinicians, and policymakers due to its strong associations with impairments across academic, social, mental health, and family domains. Traditional models conceptualize absenteeism systemically, using dimensional definitions (e.g., chronic absenteeism defined by missed days), or analytically, using categorical definitions (e.g., truancy, school refusal). Both approaches are limited in capturing the functional consequences of school attendance problems (SAPs). This study evaluated whether a functional impairment model, which emphasizes how domains of functioning are disrupted by absenteeism, provides a more accurate framework for predicting outcomes than absenteeism frequency alone. Using longitudinal data from the Adolescent …

Prepulse Inhibition And Emotion: A Systematic Review, Jennifer U. Le

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prepulse inhibition is a neurological pre-conscious sensorimotor gating mechanism by which a softer auditory sound (or prepulse) preceding a startle probe (or pulse) and subsequently reduce the magnitude of the startle blink reflex. Prepulse inhibition is deficient in many psychological disorders where emotion is a central component; however, emotion has been scarcely examined with prepulse inhibition in human studies. The current study is a systematic review that examines three databases (APA PSYCInfo, Pub Med, and CINAHL) to examine how state and trait emotion (such as happiness, sadness, anger, disgust) is related to prepulse inhibition within human subjects. The initial search …

Organizing The Life Story: The Structure, Retrieval, And Flexibility Of Autobiographical Memories, Erin Murphy

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation focused on the characteristics and flexibility of autobiographical memories within the life story, based on Conway and Pleydell-Pearce’s (2000) self-memory system and McAdams’s (2001) narrative identity theory. In two experiments, the research examined how retrieval goals and hierarchical organization influence the recall of different autobiographical memories (i.e., specific events that occur within one day, and chapters that are longer) and the flexibility of the temporal boundaries and duration of these memories. In Experiment 1, task instructions about recalling life story memories were manipulated to examine whether subtle shifts in retrieval goals influenced the type of memories recalled. Experiment …

Is Forgetting Independent Of Learning? An Examination Of Initial Learning Across Alternative Forgetting Analyses, Rhiannon Nicole Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

A long-standing debate has reappeared regarding whether the rate of forgetting is independent or dependent upon the initial degree of learning. Interestingly, both conclusions have been supported. These diverging conclusions could be due to the analytical method and operational definition of forgetting employed: Researchers supporting independence typically measure forgetting as the number of items forgotten at a given retention interval, while those in favor of dependence typically measure forgetting as the number of items forgotten between test intervals. The current study tested whether the degree of learning affects the rate of forgetting for recognition accuracy (da) and other memory processes …

Exploring Non-Native English Learners’ Attitudes Towards Ai And Online Multimedia Persuasive Opinions And The Role Of Sentiment, Zvetomira N. Svetleff

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study and various other studies use quantitative models to identify which persuasive features predict persuasiveness. Most studies in the field do not explain why participants responded as they did nor do they focus on studying adult non-native English learners also referred to as second language (L2) English learners. Despite seemingly remarkable progress on research related to how to convey persuasive messages, there has been little work related to persuasive messaging targeted at second language learners or non-native speakers. In addition, despite the increasing reliance on AI technologies and tools in language learning within educational and work settings, there has …

Examining Demographic And Contextual Differences In Stress-Related Sport Interference Among U.S. Collegiate Sport Participants, Heather Tran

UNLV Theses, Dissertations, Professional Papers, and Capstones

Collegiate athletes experience a range of stressors that may interfere with sport performance; however less is known about how stress-related sport interference varies across demographic groups and contexts. Guided by the transactional model of stress and coping, this study examined differences in stress-related sport interference by gender, race/ethnicity, and year in school, as well as across situational contexts (training, competition, and life outside of sport). Data were drawn from a secondary dataset of 288 collegiate sport participants who completed the Sport Interference Checklist (SIC). Independent samples t-test and analyses of variance (ANOVA) were used to examined demographic differences, and a …

Navigating The Unknown: Understanding The Impact Of Mentorship For First-Generation Students In Stem, Shanika Roshanie Wickramarachchi

UNLV Theses, Dissertations, Professional Papers, and Capstones

First-generation students often encounter systemic barriers and inequities in academic pursuits related to science, technology, engineering, and math (STEM). Many institutions implement mentoring programs to mitigate these challenges; however, the effectiveness of STEM mentoring relationships for first-generation college students has been underexplored in the empirical literature. The current study centers the voices of first-generation college students to explore how mentors and institutions can better support their success through STEM mentoring relationships. In addition, this study examines how mentors’ generational status informs how they approach mentoring relationships with first-generation mentees. Participants included mentors and first-generation mentees in STEM research mentoring relationships …

Project Wildest Dreams, Faith Bernier

Honors College Theses

“Project Wildest Dreams” is a hybrid psychological correlational study and short fiction collection based on anecdotes of vivid, frightening, or bizarre dreams. This collaboration of art and science explores the nature of dreaming, a phenomenon that has intrigued and perplexed both the humanities and the STEM fields for many years. The goal of this thesis was twofold: primarily, it was intended to utilize the outlandish, surreal, and unique feelings and images that dreams elicit in order to procure an anthology of surrealist and absurdist short stories across primarily the genres of horror, comedy, and fantasy. In addition to this, the …

The Use Of Video Modeling With Older Learners With Autism Spectrum Disorder To Increase Adl Skill Acquisition: A Systematic Review, Marianne Feliciano

Seton Hall University Dissertations and Theses (ETDs)

Autism spectrum disorder (ASD) is a lifelong condition that can significantly impact functional independence across the lifespan. Although video modeling is an evidence-based intervention shown to improve adaptive and daily living skills in children and young adults with ASD, its effectiveness for adults aged 40 years and older remains unclear. This systematic review examined the existing literature on the use of video modeling to increase daily living (ADL) skills and independence among older adults with ASD. A systematic review of PsychINFO via EBSCO was conducted according to PRISMA guidelines. Of 578 records initially identified, 20 full-text articles were assessed for …
