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 …

Building Collaborative Capacity For Coexistence With The Montana Beaver Working Group, Shane Randle

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Despite beavers’ recent surge in popularity, prevailing negative attitudes and the persistence of beaver removal practices remain obstacles for those advocating living with beavers. The Montana Beaver Working Group (BWG) advances beavers’ role in ecological and community resilience through members’ collaborative efforts, including beaver-related restoration and conflict resolution projects. Bringing together people with diverse values and perspectives, the BWG builds collective understanding, develops a holistic vision for beavers in Montana, and supports members in pursuing it. As the group’s impacts and membership have grown, so too has their need to adapt. For my Civic Engagement Project, I strengthened the BWG’s …

Serotonin 7 Receptor Modulation On Measures Of Working Memory And Anxiety, Antonio Gutierrez

Electronic Theses, Projects, and Dissertations

Serotonin (5-HT) function is critical in the regulation and homeostasis of several neural systems. Alterations in 5-HT levels can directly impact the presence of neuropsychiatric disorders such as schizophrenia. With a wide range of 5-HT receptors, the potential impact each of these modulators have on behavior is important to better understand. The 5-HT7 receptor is the most recently identified 5-HT receptor. 5-HT7 receptors can be found in the thalamus, hypothalamus, and several areas of the hippocampus. Modulation of these receptors impact circadian rhythms, hormonal regulation and memory function. Previous research has that 5-HT7 antagonist compounds lead to conflicting results, highlighting …

Raising Resilient Children: Parent Video Guide To Support Children’S Emotional Development, Perla F. Nunez-Chavez

Electronic Theses, Projects, and Dissertations

Social-emotional learning (SEL) in early childhood plays a critical role in

children’s ability to recognize emotions, regulate behavior, build relationships,

and succeed in academic settings. During the preschool years (ages 3–5),

children experience rapid emotional development and rely heavily on parents for

co-regulation, emotional modeling, and guidance. Research consistently shows

that when parents engage in emotion coaching practices, such as labeling

feelings, validating emotions, and modeling regulation strategies, children

demonstrate stronger emotional competence and improved developmental

outcomes. However, despite strong evidence supporting parent involvement in

SEL, many existing interventions are delivered through structured, in-person

programs that are often inaccessible to …

Game On! Level Up Your Teaching: A Digital Game-Based Learning Guide For Preschool Teachers, Scarlett Flores Marin

Electronic Theses, Projects, and Dissertations

Although digital game-based learning (DGBL) has emerged as a

promising technological advancement in early childhood education by offering

many developmental benefits for children, its effective implementation remains a

challenge. The integration of digital technologies in early childhood education has

led to the growing use of DGBL as an effective instructional approach with

research indicating that well-designed educational apps and games can enhance

young children’s cognitive, literacy, and social development by promoting active,

meaningful, and interactive learning experiences. DGBL encourages problem-

solving, critical thinking, and collaboration, aligning with how children naturally

learn through exploration and engagement. When used intentionally, technology

and …

Investigating Fentanyl-Xylazine Interactions: Implications For Opioid-Induced Hyperalgesia And Affective Dysregulation In Rats, Alejandra R. Lujan

Electronic Theses, Projects, and Dissertations

The growing prevalence of fentanyl adulterated with xylazine presents a major public health concern, yet the behavioral and physiological effects of this combination remain poorly characterized. This study examined the effects of acute fentanyl administration, alone and in combination with xylazine, on opioid-induced hyperalgesia, affective behavior, and mortality in male and female Sprague-Dawley rats (n=80). Rats received four fentanyl injections (60 µg/kg) administered at 15-minute intervals, with or without xylazine (0, 0.1, 0.333, or 1.0 mg/kg), as well as a saline control condition. Pain sensitivity was assessed using a hot plate assay at 6.5, 12, 24, and 48 hours post-injection. …

Effects Of Cannabinoid Agonist Win 55-212-2 On Latent Inhibition, Ashley Peterson

All Graduate Theses and Dissertations, Fall 2023 to Present

The endocannabinoid system (ECS) is a modulatory system that helps regulate brain functions, including learning and memory, influencing processes such as latent inhibition (LI). LI refers to the slower association formed when a familiar event is paired with a new outcome, compared to the association of an unfamiliar event. LI is a process that is often disrupted in individuals with schizophrenia and is known as a cognitive symptom. This study aimed to determine whether the drug WIN-55-212-2 (WIN), which interacts with the ECS, influences the process of LI using a fear-conditioned response procedure. The results found no significant interaction among …

Between Chronicle And Legend: A Two-Scene Environment And Visual Effects Examination Of Physical Accuracy And Emotional Exaggeration On The Honey Creek Bridge Collapse, Alison R. Gaddy

All Theses

This thesis explores how truth and dramatization intersect in digital storytelling by comparing realistic and stylized simulations of the Honey Creek bridge collapse within the context of the Kate Shelley animated short. At the core of storytelling lies a tension between factual accuracy and dramatic stylization. We investigate that tension by examining how narrative truth is conveyed, distorted, or enhanced through visual dramatization by focusing on the psychology of audience perception and the motivations behind creative embellishment. The practical contribution of this research is the development of two distinct digital scene setups depicting the same Honey Creek bridge collapse event. …

Psychological And Inflammatory Ties To Diet In Breast Cancer Survivors, Sonal Kaur Johal

Master's Theses

Breast cancer is among the most prevalent forms of cancer and is a primary cause of death among women (Wang et al., 2020). Cancer patients experience higher levels of anxiety symptoms, depressive symptoms, and inflammation compared to non-cancer patients, which can predict a diminished quality of life but also contribute to higher mortality rates among cancer patients (Bortolato et al., 2016; Song et al., 2022). Diet has the potential to impact the manifestation of depressive and anxiety symptoms in both healthy individuals and those battling cancer. This study explored the association between dietary habits, specifically cholesterol, fiber, saturated fat, added …

From Clicking To Committing: Psychological Distance And Persuasion In Online Animal Adoption Platforms To Enhance Shelter Visitation, David Goodweather

Graduate Theses and Dissertations (2019 - present)

Online animal shelter platforms have become a primary channel through which potential adopters view and evaluate adoptable animals, yet many users do not progress from online engagement to visiting a physical shelter. The dissertation examines how online pet viewing translates into intention to book a shelter visit by focusing on the roles of psychological distance and persuasive influence cues within a high-involvement decision context. Drawing on Construal Level Theory and persuasion research, a sequential process is proposed in which sustained interaction with pet profiles reduces distance-related abstraction, increasing receptivity to influence cues that facilitate movement from initial assessment to action. …

Impact Of Escitalopram On Postpartum Sleep/Wake Activity And Maternal Behaviors, Kimberly Guerrero Leon

Electronic Theses, Projects, and Dissertations

The postpartum period is characterized by profound physiological and psychological changes, including disruptions in sleep and activity patterns, which may contribute to the onset of postpartum depression. If left untreated, postpartum depression can result in long-term consequences, including cognitive impairments, emotional dysregulation, impaired maternal-infant attachment, and the onset of sleep-related disorders. Selective serotonin reuptake inhibitor (SSRI), escitalopram, is prescribed for the treatment of postpartum depression due to its efficacy, favorable safety profile, and relatively low cost. While escitalopram is considered an effective treatment for depression and anxiety, far less is known about its impact on maternal behaviors during the postpartum …

A Behavior Analytic Blueprint For Rapport-Building: Investigating The Key Elements For Success, Nelmar Jacinto Cruz

Theses and Dissertations

Rapport can be defined as a positive relationship between people built through specific actions. Building rapport can benefit organizations by improving performance and increasing work satisfaction. Despite these benefits, research on rapport remains scarce. Curry et al. (2019) completed the most recent rapport study and found that rapport-building led to increased productivity and discretionary effort. The present study replicated and extended Curry et al. (2019) and addressed three limitations of their research: the lack of a control group, the large disparity in time spent with the experimenter, and the rigidity of their rapport conversation script. The study was completed in …

Application Of Path Analysis To Determine The Impact Of Age And Sex On The Neural Circuits That Promote Nicotine Withdrawal Severity, Veronika Espinoza

Open Access Theses & Dissertations

The rising prevalence of electronic cigarette (e-cigarette) use presents a major public health concern, particularly in adolescent females who are most susceptible to nicotine use and its long-term negative health consequences. The goal of this dissertation was to utilize preclinical rodent models to understand how group differences in age and sex influence neural activation patterns in brain circuits believed to promote nicotine withdrawal. Prior pre-clinical work, conducted largely in male rodents, has established that there are two major brain pathways that modulate the behavioral effects of nicotine withdrawal. These include the mesolimbic and medial habenula-interpeduncular nucleus (MHb-IPN) pathways. To assess …

Language Control Over Structural Representation In Bilinguals, Anahy Barragan-Diaz

Open Access Theses & Dissertations

In daily life, bilinguals sometimes speak each of their languages in situations where the other language cannot be understood. To avoid saying words in the wrong language in such situations, bilinguals inhibit lexical representations from the non-target language (Green, 1998). But do they inhibit structural representations? This study investigated how inhibitory control operates over structural representations in English-dominant Spanish-English bilinguals via a picture description task. An experimental group was asked to describe dative-eliciting pictures in English (Baseline Phase), followed by dative pictures in Spanish (Manipulation Phase), and once again dative pictures in English (Target Phase), while a control group followed …

Examining The Interactive Effects Of Time Perspective And Life History On Decision-Making Patterns Among College Students: A Modified Replication Of Griskevicius Et Al. (2011b), Cameron M. Robins

Master's Theses

Griskevicius and colleagues (2011b) demonstrated decision-making patterns consistent with life history theory, called life history strategies, using an experimental design in which they randomly assigned college students to read one of two texts. The experimental condition was designed to trigger a feeling of heightened awareness of one’s own mortality, called mortality salience. Participants in this condition exhibited patterns of risk-taking and delay discounting on the outcome measures that were related to their childhood socioeconomic status (SES), one of the first demonstrations of life history strategies in an experimental setting.

However, multiple attempts at replication have failed to show similar results. …

Cross-Cultural Neuropsychological Testing: A Behavioral Item Analysis Of The Party Subtest From The Muns Battery Administered To Argentinian And U.S. Participants, Arwen A. Miranda, Alberto Luis Fernandez

Honors Thesis

In response to prevalent cultural bias in neuropsychological testing, cross-cultural tests (CCTs) were developed for accessibility across cultures through the use of “universal” stimuli. The Multicultural Neuropsychological Scale (MUNS) is a CCT developed to be appropriate across education levels, cost-effective and capable of assessing cognitive functions. The MUNS consists of seven subtests, including the Party subtest, which measures executive functioning by instructing participants to organize a party on a map. During this activity, participants purchase items such as food while remaining mindful of a 100-coin budget and minimizing travel distance. The present study examined whether the Party subtest functions comparably …

Unleashing Stress: The Effects Of Training, Bond Strength, And Stress On Pet Dog Behaviors And Health, London Maria Wolff

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Humans and dogs have formed a unique ability to communicate with each other through evolutionary and developmental mechanisms. This increased communication serves to form dynamic interspecies bonds by facilitating learning and training over the lifetime of a dog. However, it is not known what factors permit the unique capacity of dogs to form bonds with, and learn from, their human companions. Odor is a notable candidate for interspecies communication about emotional states, with studies showing that both dogs and humans use odor information to detect human emotions (Calvi et al., 2020). Possibly, this may include detection of both acute and …

Development And Validation Of The Organizational Humanization Scale, Kevin Stroop

Doctoral Dissertations and Projects

Research on humanization is fragmented, generally focuses on dehumanization, and prior to this study no validated measure of humanization existed. To fill this gap, I developed and validated the Organizational Humanization Scale (OHS), a nine-item measure defining organizational humanization as the perceived affirmation of autonomy, individuality, and dignity. Items for the OHS subscales were adapted from established measures of work autonomy, work-group uniqueness, and workplace dignity. Using a cross-sectional survey of full-time employed adults in the United States (N = 427), I evaluated the OHS’s internal consistency reliability and evidence of structural, convergent, discriminant, and nomological validity. Results supported a …

The Interactions Of Faith Development, Attachment With Relational Authenticity, And Theory Of Mind In Children With Adverse Childhood Experiences, Lisa Haley

Doctoral Dissertations and Projects

Early exposure to adverse childhood experiences (ACEs) interrupts typical spiritual, socioemotional, and cognitive developmental trajectories. Faith Development (FD), attachment with Relational Authenticity (RA), and Theory of Mind (ToM) may serve to provide positive coping strategies for children with ACEs. Few studies explored the interactions of FD, attachment with RA, and ToM in children. Additionally, sparse research involved RA independently or in relation to attachment formation. The purpose of this phenomenological study was to explore how FD, attachment with RA, and ToM interact in children with ACEs. The lived experiences of children with ACEs and the interactions of FD, attachment with …

Creating An Unconscious: Toward A New Ethic Of Residential Treatment, Daniel Garcia

Middle Voices

What is currently nominated “residential treatment” for serious mental illness (SMI) has a long and varied history. From its earliest version as houses for the unproductive, to confinement of and with the unruly and criminally dangerous, to asylumdom, residential treatment has always sought to protect society from those it perceives as actively trying to revoke it. Consequently, the remedies prescribed in defense of civilization have also ranged from the gruesome to the utopian and the seat of responsibility for maintenance of the social order has vacillated between the family and the church, the local community and the state, the psychiatric …

Dynamic Individualized Latent Trait (Dilt) Model: Bridging Nomothetic And Idiographic Psychometrics, Muchen Xi

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation aims to develop an analytical framework that bridges the long-standing divide between nomothetic and idiographic approaches to defining the structure of personality and other individual differences. The nomothetic tradition seeks to explain and predict behavior through stable, universal dimensions of personality, while the idiographic approach emphasizes the fine-grained, dynamic processes unique to individuals. Although theoretical advances have begun to reconcile these perspectives, analytical methods capable of integrating them remain underdeveloped. To address this gap, I introduce the Dynamic Individualized Latent Trait (DILT) model, a framework that decomposes ordinal item responses from intensive longitudinal data into three components: 1) …

A Trauma Psychology Approach To Space Psychology And Long-Duration Space Travel In Consideration Of Isolation, Resource Scarcity, And Group Dynamics., Alden Nicoll

Honors Projects

As modern societies research and prepare for long-duration deep space travel, psychological research becomes increasingly prevalent into understanding the effects of trauma on the psyche. This present study looks at the current research outcomes of “Team Dynamics”, “Social Isolation”, and “Resource Scarcity” within the literature of Space Psychology. Current research on social isolation is taken from past missions in outer space and analog missions in Antarctica, at sea, and prison research. While research is vast on social isolation, it doesn’t consider how trauma could be intensified with both time and duration in space. Next, when considering team dynamics and how …

Exploring Lay Meanings Of Happiness In Contemporary India: A Qualitative Inquiry, Kunmun Mishra, Kailash Bl Srivastava Professor

The Qualitative Report

Three decades of professional research suggest several explicit concepts of happiness; however, exploring the lay theories of happiness has largely been overlooked. Addressing this gap, our paper attempts to explore lay concepts of happiness in the contemporary Indian context. Given the inherently subjective nature of happiness, a qualitative study was conducted to explore the impact of beliefs and lived experiences on happiness. Data were collected through semi-structured in-depth interviews, and transcripts were analyzed using thematic analysis. Meanings, causes, and actions to maintain happiness evolved into seven significant themes: contentment, achievement and hope, collectivist orientation, autonomy, materialism, pragmatic orientation, and spirituality. …

A Single Administration Of Psilocybin Is Ineffective In Reversing Ptsd-Like Sequelae In A Rat Model Of Stress-Enhanced Fear Learning, Kylie M. King, Marisa J. Savini, Noelle M. Molnar, Evelynn J. 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 …

Impact Of Caffeine On Participant Memory For A Stressful Experience And The Development Of Intrusive Memories, Jaycee L. Kirkland, Kaylina R. Mcclenen, Natalina E. Porter, Sarah M. Wood, Julia Gross, Madilyn E. Paphanchith, Kelsey M. Siereveld, Jasmine Ic Ifeakanwa, Caeden M. Gurganus, Koen N. Suzelis, Aiden J. Farrell, Boyd R. Rorabaugh, Phillip R. Zoladz

ONU Student Research Colloquium

Most individuals consume caffeine on a daily basis. Research has shown that caffeine stimulates the release of glucocorticoids and catecholamines and can enhance cognition. Caffeine also amplifies stress-induced increases in arousal and aggravates PTSD-like symptoms. Thus, we examined the impact of caffeine on memory for a stressful experience and intrusive memories related to that experience. Undergraduate students ingested caffeine or a placebo. Thirty minutes later, they were exposed to the Trier Social Stress Test (TSST; stress condition) or friendly-TSST (f-TSST; control condition), both of which were designed to enable participant memory for the experiences to be quantified. In each condition, …

Age, Income, And The Discounting Of Delayed And Probabilistic Rewards: The Roles Of Financial Resources And Attribute Salience, Haoran Wan

Arts & Sciences Graduate Student Theses and Dissertations

Many everyday decisions involve outcomes that are both delayed and probabilistic. Although previous research has reported inconsistent age-related effects on discounting, few studies have taken into account the multi-attribute nature of real-world choices or the moderating role of financial resources. Accordingly, the present research examined the interactive effects of age, income, and multi-attribute contexts to test how resource constraints and task dimensionality moderate attribute salience. Across two studies (total N = 600), stratified samples of younger (35-45) and older (62-72) adults with lower (<$60,000) and higher (>$100,000) annual household incomes completed standard and multi-attribute adjusting-amount discounting tasks. In Study 1 (Delay Discounting), …

Paws And Predictions: Interpreting Intraspecific Cat Social Interactions Through Facial Signals, Levi Neal, Lauren Scott, Gosia Zobel, Brittany Florkiewicz

People and Animals: The International Journal of Research and Practice

There has been limited research on humans’ ability to perceive and predict social interactions among cats using facial signals. This area is crucial to explore since conflicts between cats often cause significant stress for their guardians. By evaluating individuals’ skills in understanding cat interactions, researchers can develop tools to help guardians predict affiliative and nonaffiliative behaviors, leading to effective intervention strategies for multicat households. We distributed a survey to individuals subscribed to the Companion Animals New Zealand newsletter to assess cat guardians’ effectiveness in perceiving and predicting various social interactions among cats. We hypothesized that guardians with one or more …

Psychosocial Characteristics Of North American Male Cannibals, Sheila A. Murphy

Walden Dissertations and Doctoral Studies

Criminal cannibalism is a rare form of violent offending that remains understudied despite public attention. This gap limits understanding of the psychosocial characteristics and life experiences of individuals who engage in cannibalistic behavior. The purpose of this qualitative study was to explore psychosocial characteristics within the life experiences of North American males who engaged in cannibalistic behavior and identify common themes. Grounded in social control theory and self-control theory, the study examined how weakened social bonds and diminished self-regulation may relate to extreme deviance. The guiding research question focused on identifying common psychosocial characteristics within this population. A descriptive phenomenological …
