The Role Of Perceived Perpetrator Centrality In Intentions To Express Or Confront Sexist Behaviors, Anna G. Miller May 2026

The Role Of Perceived Perpetrator Centrality In Intentions To Express Or Confront Sexist Behaviors, Anna G. Miller

Theses/Capstones/Creative Projects

Confronting sexist acts (e.g., by saying, “That was sexist!”) has been empirically shown to reduce others’ sexist behaviors. However, bystanders are often reluctant to confront sexist acts, particularly when perpetrators of sexism are perceived as high in status. Prior studies have operationalized status in terms of organizational rank. However, individuals may also have status by virtue of their connections to other group members, which I investigate in the present study. Participants with full-time work experience (N = 451) were asked to read a vignette describing a sexist incident in which a male perpetrator of sexism had many (vs. few) …


“Am I A Criminal?”: How College Students Conceptualize Misconduct And Crime, Talia J. Norby May 2026

“Am I A Criminal?”: How College Students Conceptualize Misconduct And Crime, Talia J. Norby

Theses/Capstones/Creative Projects

Institutions of higher education play a critical role in regulating student behavior; however, existing research has given limited attention to how students themselves interpret conduct addressed through campus disciplinary systems. The present study examined how college students differentiate institutional misconduct from crime in university settings and whether those judgments are associated with perceptions of institutional legitimacy. Data was collected through an online Qualtrics survey administered to 146 students at the University of Nebraska at Omaha. Participants were presented with six vignette-based scenarios depicting campus-relevant behaviors and asked to classify each as criminal or non-criminal, rate its perceived severity, and identify …


Soft Skills In The Workplace: A Comparative Analysis, Meg Rothfuss May 2026

Soft Skills In The Workplace: A Comparative Analysis, Meg Rothfuss

Theses/Capstones/Creative Projects

Soft skills are defined as any non-technical ability related to how you do your work. While hard skills are commonly thought of first when it comes to job responsibilities, soft skills are increasingly important to the success of any role. Soft skills can be broken into the broad categories of cognitive, interpersonal, and intrapersonal skills. The goal of this study was to define the soft skill profiles of different industries and compare the similarities and differences across industries. To do this, an interview and survey were conducted including employees from a variety of industries. The interviews compared the IT and …

The first goal of this study was to observe changes in self-determination satisfaction and frustration, self-esteem, self-efficacy, and disability awareness after one semester of enrollment in the program. There were 16 participants in the study who varied in their length of participation in the program. Dependent t-tests revealed a statistically significant decrease …


Choosing Death: The Moral Legitimacy Of Voluntary Active Euthanasia, Emma Rougeou May 2026

Choosing Death: The Moral Legitimacy Of Voluntary Active Euthanasia, Emma Rougeou

Honors Theses

During the last three decades, the issue of physician assisted suicide has captivated the interest of private citizens and state legislatures. Thinking about the matter of end-of-life concerns, particularly surrounding euthanasian (practices that hasten the deaths of suffering terminally ill people) have shifted. Views of private citizens and state-level legislation reflects a “slow shift to more permissive attitudes” (Cohen et al., 2012). Meanwhile, as recently as March 2026, state legislators in conjunction with the NY State Governor, passed a bill legalizing medical aid in dying for terminally ill patients. This thesis is intended to thoughtfully contribute to meaningful discourse on …


Sustainability Savvy: The Role Of Competence And Efficacy In Promoting Pro-Environmental Behavior, Lorenna Graham May 2026

Sustainability Savvy: The Role Of Competence And Efficacy In Promoting Pro-Environmental Behavior, Lorenna Graham

Environmental Studies Honors Projects

Combatting environmental issues requires both large-scale and individual change. While many understand that personal pro-environmental behavior (PEB) is necessary, individuals do not always engage in this behavior (Hines, 1986, Goh, 2022). Thus, there is a need to investigate psychological factors which encourage PEB. Prior research suggests competence and outcome efficacy as likely PEB predictors (Bentler, 2023, Lavergne & Pelletier, 2015, Priolo, 2016), while cognitive dissonance has been shown to both encourage and discourage PEB (Bouwman, 2022, Dickerson, 1992, Ehrich & Irwin, 2005). Study 1 investigates the relationship between cognitive dissonance and PEB with competence and outcome efficacy as potential moderators. …


Leading The Choreography: Preserving Creative Agency In Ai-Supported Problem-Solving, Mikhaila Ackerbauer May 2026

Leading The Choreography: Preserving Creative Agency In Ai-Supported Problem-Solving, Mikhaila Ackerbauer

Creativity and Change Leadership Graduate Student Master's Projects

As artificial intelligence tools become increasingly present in creative and problem-solving contexts, a critical question emerges: how can users engage with AI in ways that preserve rather than erode their own creative capacity? This project explores that question through research synthesis, practitioner conversations, coursework, international conference presentations, and the development of custom AI chatbots trained in the Creative Problem-Solving process. The central finding is a theoretical triangle comprising three interdependent capacities: autonomy, creative self-efficacy, and critical thinking. Grounded in Rhodes' (1961) Four P's framework, the triangle sits within the Person dimension. Convergent themes across the literature, practitioner conversations, and direct …


Why Don’T They Leave? : An Exploration Of Barriers That Prevent Women From Leaving Relationships Where They Experience Intimate Partner Violence, Jaelene Beltre May 2026

Why Don’T They Leave? : An Exploration Of Barriers That Prevent Women From Leaving Relationships Where They Experience Intimate Partner Violence, Jaelene Beltre

Theses and Dissertations

Relationships involving intimate partner violence (IPV) can often entail physical or verbal abuse from one individual to another in a romantic relationship. In a heterosexual relationship, the abuse most often occurs from the man to the woman. From an outside perspective, when considering the victims of abuse, one might ask simply, “Why don’t they leave?” However, the answer to this question, much like the abuse experienced in these dynamics, is nuanced. The present study is a literature review of studies meant to answer this very question. Abuse can often be some combination of physical, verbal, emotional, sexual, or financial. We …


Using Behavioral Monitoring To Assess Activity Patterns And Welfare Indicators In Captive Black Howler Monkeys (Alouatta Caraya), Ramiro Gomez Iii May 2026

Using Behavioral Monitoring To Assess Activity Patterns And Welfare Indicators In Captive Black Howler Monkeys (Alouatta Caraya), Ramiro Gomez Iii

Theses and Dissertations

This study examined activity patterns and potential welfare indicators in captive black howler monkeys (Alouatta caraya) using behavioral monitoring techniques. A monogamous pair housed indoors at Gladys Porter Zoo was observed using focal sampling methods, and a species specific ethogram was developed to systematically record behavior. A total of 1,750 minutes of data were collected over one year. Observed behaviors were categorized into five groups: affiliative, agonistic, stationary, locomotion, and stereotypic behaviors. Activity budgets were calculated to determine the proportion of time allocated to each behavioral category. Results indicated that affiliative behaviors, particularly physical contact, dominated the activity budget, while …


Keeping Track Of Time: Does Formal Education Of Temporal Symbols Refine People's Ability To Perceive Time?, Alyssa Gabrielle Smith May 2026

Keeping Track Of Time: Does Formal Education Of Temporal Symbols Refine People's Ability To Perceive Time?, Alyssa Gabrielle Smith

Undergraduate Honors Thesis Collection

While many studies find a relation between symbolic and nonsymbolic numerical abilities (e.g., Chen & Li, 2014), whether this relation is causal has been questioned. For example, does learning symbols refine nonsymbolic abilities (i.e., Refinement Hypothesis)? One study found that as children gained proficiency in their verbal counting abilities, their nonsymbolic numerical acuity increased (Shusterman et al., 2016), thus supporting the Refinement Hypothesis. As studies have found similar processing for numerical and temporal abilities (e.g., Walsh, 2003) and a similar relation between symbolic and nonsymbolic timing abilities has been found (e.g., Hamamouche & Cordes, 2020), it begs the question of …


Assessing Trauma Competence Among Title Ix Practitioners: Analyzing Self-Perceived Capability And Associated Factors, Aliena Hansen May 2026

Assessing Trauma Competence Among Title Ix Practitioners: Analyzing Self-Perceived Capability And Associated Factors, Aliena Hansen

Honors Program: Senior Projects (Public)

Sexual assault remains a persistent issue on college and university campuses, and the way institutions respond to survivors can significantly influence their well-being and willingness to seek support. Title IX Practitioners are often responsible for responding to reports of sexual misconduct, making trauma-informed approaches essential in their work. However, relatively little research has examined how practitioners perceive their own trauma-related capabilities. The present study examined self-perceived trauma competence among Title IX Practitioners and explored factors associated with differences in perceived competence. Participants completed a survey assessing their confidence in applying trauma-informed principles when working with complainants. Results indicated variability in …

The purpose of this study was to develop and implement a curriculum-based project designed to educate college students about neurodiverse experiences and improve knowledge, empathy, and understanding. The curriculum was administered in two formats: an in-person format with pre- and post-survey measurements and an online “choose your own adventure” implementation utilizing post-survey measurements. Participants engaged in simulated cognitive and sensory activities that represented experiences associated with dyslexia, ADHD, dysgraphia, and dyscalculia. Although limited by a small sample size, reliance on self-report measures, lack of a pre-survey …


Perceived Campus Safety And Psychological Flexibility As Moderators Of Posttraumatic Stress And Anxiety Following Indirect Exposure To School Gun Violence, Samara Trout May 2026

Perceived Campus Safety And Psychological Flexibility As Moderators Of Posttraumatic Stress And Anxiety Following Indirect Exposure To School Gun Violence, Samara Trout

Honors Theses

The growing prevalence of gun violence in school settings within the United States, combined with extensive media coverage of these events, has heightened concerns regarding the psychological impact of indirect trauma exposure among students. The present study examined associations between indirect exposure to gun-based school violence and symptoms of posttraumatic stress and anxiety among undergraduate students at Western Michigan University (WMU). A secondary aim was to explore whether perceived safety and psychological flexibility/inflexibility moderated associations between indirect exposure and psychological distress. Using a cross-sectional correlational design, undergraduate students (N = 33) completed a self-report survey containing screening assessments, attention …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk May 2026

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …


Listening To Those Who Stay: Support Systems Influencing Special Education Teacher Retention, Carol Jean Dawson May 2026

Listening To Those Who Stay: Support Systems Influencing Special Education Teacher Retention, Carol Jean Dawson

Electronic Theses and Dissertations

Retention among special education teachers is a constant challenge across the country. Educators in these positions often have heavy workloads, emotionally demanding responsibilities, and complex caseloads leading to burnout and high turnover rates. Despite these challenges, most of them persevere in the field for extended periods, which indicate that robust and effective support systems are essential to aiding their commitment. In examining this phenomenon, this qualitative study focused on the lived experiences of six special education teachers who worked in the same school setting for a minimum of five years with the aim of identifying support structures that affect motivation, …


A Phenomenological Study: The Cultural Identity Of Black Transfer Students In Higher Education, Briana Lashon Levi May 2026

A Phenomenological Study: The Cultural Identity Of Black Transfer Students In Higher Education, Briana Lashon Levi

Electronic Theses and Dissertations

This qualitative phenomenological study explored the lived experiences of Black transfer students from the California Community College system to Southern Historically Black Colleges and Universities (HBCUs). Guided by two theoretical frameworks, Afrocentric Pedagogy and Black Identity Development Theory (BIDT), the study investigated how participants described and interpreted their cultural identity as they transitioned from a community college to a Southern HBCU. In this study, cultural identity was understood as a holistic construct that included students’ sense of belonging and their experiences of cultural affirmation, which functioned as core components rather than separate constructs from cultural identity. This research specifically focused …

Why Do Teachers Leave? Investigating Teacher Attrition In A New Orleans Charter School: A Qualitative Phenomenological Case Study, Carlos J. Machuca Rivera

Electronic Theses and Dissertations

The purpose of this phenomenological case study was to investigate the lived experiences of former teachers who worked at Goodlife Academy (GLA), a charter school in New Orleans, Louisiana, between 2019 and 2025, with particular attention to how teachers experienced job satisfaction and job dissatisfaction and how those experiences influenced their decisions to leave Teacher attrition—defined as educators leaving their school or the profession—has been associated with factors such as burnout, inadequate support, low compensation, and persistent challenges in addressing achievement gaps. Although these factors are well documented in the literature, many existing studies rely on quantitative methods and focus …


Factors Affecting Pedestrian-Vehicle Conflicts: An Empirical Analysis, Christo D. Jamo May 2026

Factors Affecting Pedestrian-Vehicle Conflicts: An Empirical Analysis, Christo D. Jamo

Honors Scholar Theses

The number of pedestrian deaths increased by 78% between 2009 and 2023, while other motor vehicle crash deaths increased by 13% in the same period [1]. To identify potential pedestrian safety measures, this study analyzed the effects of location-based demographics, pedestrian phasing type, and other physical infrastructure and behavior variables on the probability of pedestrian-vehicle conflicts at signalized intersections, which is a surrogate measure of crash risk. Data were collected from 55 intersections in Connecticut, and the pedestrian-vehicle interactions were classified by severity based on the Swedish Traffic Conflict Technique: undisturbed passage, potential conflict, minor conflict, or serious conflict. Because …


The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi May 2026

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 …

Task-Dependent Modulation Of The N170 Erp Component In Facial Perception, Mary M. Krdikashyan May 2026

Task-Dependent Modulation Of The N170 Erp Component In Facial Perception, Mary M. Krdikashyan

Electronic Theses, Projects, and Dissertations

The N170 component plays a key role in face perception, but how attention influences it remains debated. In a series of five electroencephalography (EEG) experiments, we examined how attention to different facial features (holistic versus feature-based) affects the N170 amplitude. This study aims to determine whether perceptual competition explains these effects. In a preliminary study (Experiment 1), participants were primed to focus on either gender, age, emotional expression, race, or no specific task. This study showed a larger amplitude for gender and age, followed by emotion, with minimal differences for race, and no task was assigned. Since all these conditions …


The Relationship Between Telecommuting, Autonomy, And Burnout, Aniko Nagy May 2026

The Relationship Between Telecommuting, Autonomy, And Burnout, Aniko Nagy

Electronic Theses, Projects, and Dissertations

With flexible work arrangements becoming more common, the need to expand our understanding of the relationships between flexible work arrangements and employee health and wellbeing outcomes, such as employee burnout, continues to grow. The purpose of the present study is to explore the relationships between flexible work arrangements, autonomy, and employee burnout. The Job Demands-Resource (Bakker and Demerouti, 2007) and Conservation of Resources (Hobfall & Freedy, 2017) theories propose that job resources such as flextime, flexplace, and job autonomy are vital, and that the loss of or failure to acquire job resources can lead to stress and burnout. The Self …


Raising Resilient Children: Parent Video Guide To Support Children’S Emotional Development, Perla F. Nunez-Chavez May 2026

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 …


Face Representations In The Fusiform Face Area, Krisha Orgo May 2026

Face Representations In The Fusiform Face Area, Krisha Orgo

Electronic Theses, Projects, and Dissertations

Faces are among the most socially significant stimuli humans encounter, requiring recognition not just at the category level but at the level of individual identity. While the fusiform face area has been established as a dedicated region for face processing, whether it encodes distinct representations for different individuals or simply detects the presence of a face remains an open question. Evidence for identity-specific coding in the brain has come primarily from invasive single-neuron recordings in epilepsy patients, leaving open whether the same principles govern face processing in healthy populations. The present study addressed this gap using scalp electroencephalography to examine …
