Evaluating The Motivations Of Participants In Online Equine Extension Courses, Sarah Vos

Department of Animal Science: Dissertations, Theses, and Student Research

Traditional program evaluations emphasize participant demographics, knowledge gain, behavior change, and program impact. However, evaluating participant motivation can provide addition insight into why participants enroll in extension programs and help explain participant engagement and persistence throughout a program. The purpose of this study was to evaluate participant motivation in two online equine extension courses and examine potential relationships between motivation, demographics, and course delivery method, and describe participant engagement in Virtual Horse Judging Camp (VHJC). This cross-sectional study utilized convenience sampling of participants in two online equine extension courses, Horse Adult Leader Training and Educational Resource (HALTER) and VHJC. The …

The Influence Of Shape Complexity And Exploratory Behavior On Grasping, Mckenzie Gunter

Dissertations

People can orient and configure their hands in many ways in order to grasp objects. The current study investigates how object shape and hand placement influence graspability of objects, and how experimentally imposed constraints on grasping type alter grasping behavior. In a recent study, Gunter and Hajnal (under review) found that the ratio of object curvature and maximal handspan is the variable that defines the affordance of graspability. The current study aims to extend these findings by employing a more precise measurement of finger placement in two experiments using 3D printed objects as stimuli. To capture varying complexities of object …

Vulnerability In The Dark Triad: Insecure Attachment And Relational Aggression In The Peer Relationships Of College Students, Summer Boggs

Dissertations

Research on relational aggression (i.e., a type of aggression in which the aggressor harms others by damaging their relationships, reputation, and/or feelings of social acceptance) with college students has identified several important correlates, including anxious and avoidant attachment styles. Moreover, the personality traits captured by the Vulnerable Dark Triad (VDT; i.e., borderline, the antisocial component of psychopathy, and vulnerable narcissism; Miller et al., 2010) have demonstrated positive relationships with both relational aggression and insecure attachment. This study examined the relationship between insecure attachment and relational aggression among college students (N = 560), testing VDT traits as partial mediators of …

Mindful Classrooms: Teachers Co-Designing And Implementing Mindfulness Interventions, Mary L. Phan

All Graduate Theses and Dissertations, Fall 2023 to Present

Teachers play a critical role in supporting student learning and well-being, yet many experience high levels of stress, burnout, and increasing job demands. Stress can negatively affect teachers’ mental health, job satisfaction, and classroom environments, making it important to identify practical and sustainable ways to support teacher well being. Mindfulness practices, which encourage individuals to focus on the present moment with awareness and acceptance, have shown promise for reducing stress and improving emotional well-being. However, little is known about how mindfulness programs can be adapted to fit the realities of elementary school classrooms and whether teachers can successfully implement these …

Knowledge, Physician Communication, And Psychological Predictors Of Willingness To Engage In Dementia Risk Reduction Across The Lifespan, Thomas Fisher

Dissertations

Dementia represents a growing global public health concern, with increasing evidence suggesting that a substantial portion of dementia risk may be attributable to modifiable lifestyle and health-related factors. However, relatively little is known about public knowledge of these risk factors, willingness to engage in dementia risk reducing behaviors, and psychological factors that may be associated with willingness. The present study examines these factors among adults living in the United States across the lifespan. Participants (N = 308) completed an anonymous online survey assessing dementia risk-factor knowledge, willingness to engage in dementia risk reducing behaviors, primary care provider communication regarding dementia …

Black Adolescents' Understanding Of Racial Trauma: An Interpretive Phenomenological Analysis, Winifred Wilson

Dissertations

Over the past two decades, scholars have increasingly recognized that chronic stress from racism can cause racial trauma in Black individuals. However, research on the impact of racial trauma on Black adolescents remains limited. Understanding the language and experiences of Black adolescents is essential for identifying and addressing the biopsychosocial effects of racial trauma. This study used interpretive phenomenological analysis to examine how 12 Black adolescents (9 boys, 3 girls, aged 14-17) from the Midwest conceptualize, experience, and cope with racial trauma. Participants completed two interviews: an initial session exploring their understanding and experiences, and a member-checking interview (completed by …

Switches And Witches: Exploring The Relationships Between Religious Struggles, Spiritual Beliefs, And Well-Being, Emma J. Trierweiler

Psychology Theses & Dissertations

This study examined the mechanisms between interpersonal and doubt-related struggles and well-being outcomes in a formerly religious sample. The focus of this dissertation was to analyze the mediating roles of disengagement from God and perceived social support. Approach toward God was also examined as a control but not specified to be connected to the well-being outcomes given the emphasis on formerly religious individuals’ experiences. This was a retrospective study, where participants were asked to consider their responses as they relate to the time they were pulling away from religion. Three measures of well-being were explored using structural equation modeling. Positive …

Retention During Turbulent Times Of Higher Education: Modeling Intent To Leave Academia For Research University Faculty, Jordan Monroe Ball

Psychology Theses & Dissertations

University faculty operate as the lifeblood of any institution given that their job requires a “double duty” to develop both scholarly research and student minds. Due in large part to these expectations, research shows a long history of poor mental health for faculty, which ultimately results in faculty turnover. One model of faculty work motivation (Padilla et al., 2023) details the way in which the faculty work environment influences their mental health, and subsequently informs their job satisfaction, organizational commitment, and intent to leave academia, which serves as a proxy for turnover. Retention related issues have not been a pressing …

Effects Of Single-Session Interventions On Youth Internalizing Problems, Thomas K. Franzmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Anxiety and depression are among the most common mental health concerns young people face, and they often interfere with school, friendships, family life, and long-term well-being. Even though effective therapies exist, only about half of youth who need care ever receive it, and among those who do start treatment, the most common total number of sessions a young person attends is one. This gap between what young people need and what they actually receive raises a practical question for the field: can a single, well-designed meeting with a provider produce meaningful change for some youth and families, and what should …

Affective And Cognitive Factors Contributing To Male-Female Differences In Mathematics, Sarah N. Herod

All Graduate Theses and Dissertations, Fall 2023 to Present

Math differences between men and women have been studied for several decades, with original theories suggesting a biological reason for the differences and more new ones suggesting multiple factors, such as self-efficacy, anxiety, and spatial ability, may be responsible for these apparent differences. Additionally, most research into math differences between the sexes involves the use of a composite score, rather than examining the different sub-domains of math separately. The purpose of the current study was to examine the relationship between sex and math performance within the context of an individual's belief and attitudes towards math and spatial information. Seventy-one participants …

Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen

Electronic Theses and Dissertations

Risky behaviors, actions that may cause physical, psychological, social, or economic harm to oneself or others, are prevalent among college students. While significant research has focused on single high-risk behaviors of alcohol use, drug use, gambling, and gaming separately, students frequently engage in multiple high-risk behaviors simultaneously, such as drinking alcohol while gambling. Research shows that students have distinct and specific expectancies about what happens when they engage in a risk behavior, however, minimal research has examined students’ perceptions or reasons for simultaneous poly-risk behavior engagement. This multi-phase project characterized students’ outcome expectancies for simultaneous poly-risk behavior combinations, developed and …

Predicting Student Belonging In Computing Education: A Multimodal Machine Learning Approach Using Eeg And Survey Data, Hannah Moshtaghi

Master's Theses

Measuring students’ sense of belonging, characterized by feelings of acceptance, inclusion, and encouragement from teachers, remains a significant challenge in computing education. Prior research has associated this multidimensional construct with positive academic outcomes and has identified instructors’ growth- and fixed-mindset messaging as a potential influence. However, belonging is a complex and deeply personal experience that is difficult to capture through direct observation alone. Current measurement methods rely on self-report surveys, which may not capture every aspect of an experience that can also involve emotional and cognitive responses.

This thesis investigates whether combining EEG data recorded during a belonging questionnaire with …

Impact Of Repeated Serotonin 6 Receptor Activation On Weight And Anxiety In C57bl/6j And Btbr Mice, Pedro Flores

Electronic Theses, Projects, and Dissertations

Selective Serotonin Reuptake Inhibitors (SSRI) are the most common form of medication prescribed to people with anxiety disorders. One of the most common side effects is weight gain. This weight gain often leads to the suspension of treatment. This has led to studies focusing on specific serotonin (5-HT) receptor targets for modulating depression and anxiety. Studies examining 5-HT6 antagonist treatment have shown that they reduce body weight as well as produce brain specific changes. Less is known regarding 5-HT6 receptor agonists, although previous literature has shown that exposure to high doses produces weight loss but not at lower doses, while …

What Makes A Cozy Game Cozy? Looking Through The Lens Of Feminism And 4e Cognition, Mary Catherine M. Wilcox

All Theses

Why do some games feel cozy, and others miss the mark, even if they are tricked out in bright colors and festooned with bows? This thesis examines the emerging genre of “cozy games” to better understand why some titles successfully evoke comfort and relaxation while others fail, despite relying on conventionally cute aesthetics or farming-sim mechanics. Although cozy games have grown rapidly in popularity over the past decade, the genre remains under-studied and is often dismissed as frivolous, reflecting the broader historical devaluation of media associated with women. Accordingly, this study argues that understanding cozy games requires examining women’s relationship …

Can Employees Report Stress-Related Problems Without Repercussions? Understanding The Determinants Of Stress Stigma, Kristieona L. Epting

All Theses

Few studies examine the stigma associated with reporting stress-related work concerns, or stress stigma. When employees refrain from communicating their experience of stressors due to the worry of negative repercussions, leaders become unable to gain full insight into the organizational factors causing stress. Learning more about employees’ reluctance to communicate stress concerns can help companies identify workplace stressors. Additionally, prior research has shown that an individual's core self-evaluation (i.e., fundamental evaluation of self) influences how they interpret and react to environmental situations. Individuals with higher levels of CSE may experience fewer adverse consequences from unfavorable job characteristics than a person …

Beyond Going Green: A Multilevel Examination Of Sustainability Climate Formation, Meredith Pool

All Dissertations

Going green at the organizational level does not automatically produce a shared sustainability climate among employees. How individual perceptions of organizational sustainability support form, and under what signal conditions they converge, has been theorized but rarely tested experimentally. The present study examined these questions using a 2 × 2 × 2 between-subjects factorial vignette experiment (N = 332) with full-time employed adults, manipulating organizational sustainability signal strength (strong vs. weak), team-level sustainability signal strength (strong vs. weak), and team functional context (operations vs. analytics). Two large main effects emerged. Organizational signal strength produced a large effect on Perceived Organizational Sustainability …

A Socio-Cognitive Process Theory Of Error Response: Evidence From Shot Selection In Basketball, Jordan Britt

All Dissertations

Errors in organizational research have traditionally been conceptualized as static, preventable outcomes as opposed to dynamic events embedded within changing social environments. This dissertation reframes this by conceptualizing post-error response as an ongoing identity-regulation process. Drawing from self-presentation theory and identity control theory (ICT), it was hypothesized that an error’s deviation from expectation and its social context (self, teammate, or opponent error) influence post-error caution. These results were hypothesized to be greater when audience salience and situational importance were higher. Using play-by-play shot selection data from the 2023-2025 NCAA Division I basketball seasons as a natural testing environment, this study …

Can Kinematics Specify Tool Use Affordances?, Tyler Duffrin

All Dissertations

Object properties such as length, shape, and heaviness, as well as affordance-based properties such as strike-with-ability and poke-with-ability, can be perceived via dynamic touch as functions of inertia tensor invariants. The primary question addressed here was whether people can perceive these same power and precision properties for purely virtual objects, which lack dynamic physical forces. The Kinematic Specification of Dynamics (KSD) principle asserts that missing dynamics are lawfully specified by kinematic (visual) motion patterns, such that kinematic information alone may support successful interactions with virtual objects. In three experiments, we investigated (1) whether virtual reality (VR) users could calibrate to …

A Critical-Constructivist Grounded Theory Exploration Of The Mental Health Experiences Of Individuals With Intellectual Disabilities In Post-Secondary Settings, Alyssa L. Decker

Dissertations, 2020-current

Individuals with intellectual disabilities (ID) now have access to higher education, often through inclusive post-secondary education programs (IPSE), to increase employability and quality of life. IPSE programs, historically, have provided academic and life skill support and not mental health support within programs’ curricula. A recent review of IPSE programs reveals that if mental health services are included, they are often accessed through university health services. Transitioning from high school to college induces high levels of stress, which can exacerbate underlying mental health conditions. Mental health care is defaulted to an already overburdened college counseling center without the knowledge and skills …

The Ambivalent Wisdom Of Moral Disgust, Brandon Yip

Research Collection School of Social Sciences

This paper has two aims. First, to provide a positive account of moral disgust. I suggest that moral disgust is a response to acts that are socially corrosive, namely, acts that undermine the normative structure to which an agent is attuned. I support this analysis with two lines of evidence: (1) moral disgust serves the important function of guarding normative structures from socially corrosive actions and (2) the analysis provides an illuminating explanation of moral disgust in a wide variety of cases. The secondary aim of this paper is to probe the normative implications of my positive account. I suggest …

Global Prevalence Of Depression Among University Students: A Comprehensive Umbrella Review, Gilda Yun Kai Sam, Xun Ci Soh, Harshitha Balaji, Gabriel X. D. Tan, Shu Fen Diong, Meilan Hu, Andree Hartanto, Nadyanna M. Majeed

Research Collection School of Social Sciences

Depression has become a major concern for educational institutes due to its increasing incidence and detrimental impacts on students’ well-being. However, its global prevalence in the context of tertiary education remains unclear. This umbrella review summarised existing meta-analyses and systematic reviews to examine the worldwide prevalence of depression among university students. Several sociodemographic and methodological factors, including differences in depression prevalence before, during, and after COVID-19, were examined as moderators. Structured and exhaustive searches were conducted in five bibliographic databases and five journals, alongside two sources of grey literature. A total of 61 meta-analyses and systematic reviews were included in …

When The Best-Fit Model Is Not Best: The Glass Slipper Fallacy And Latent Growth Mixture Modelling, Jonathan L. Chia, Markus Wettstein, Andree Hartanto

Research Collection School of Social Sciences

Despite the use of latent growth mixture modelling (LGMM) to study longitudinal changes, existing practices may inadvertently impede this very investigation. Although subgroup trajectories may theoretically differ in their structure (e.g., some subgroups being linear, some curvilinear), the current convention advocates overreliance on the baseline model to derive subsequent profile trajectories, which may obscure these structural differences. In this article, we provide a brief description of extant LGMM practices, after which we explicate the pitfalls of the current approach. Finally, we provide a principled approach for LGMM research moving forward. Specifically, we recommend specifying a set of theoretically plausible models …

Caring With Ai: The Efficacy Of A Customised Chatgpt-Delivered Self-Compassion Intervention On College Students' Well-Being And Academic Functioning, Tracy Xi Chen, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

College students face various challenges, including academic pressure, social stress, and the transition into adulthood, which can lead to increased anxiety and other mental health issues. By recognizing personal struggles as part of a shared human experience and responding with kindness, self-compassion serves as a powerful strategy for enhancing resilience, facilitating better well-being and performance outcomes. Although effective, Compassion-Focused Therapy often requires substantial resources and time, limiting its applicability to college students. To overcome these barriers, the current study designed and evaluated Your Self-Compassion Companion, a ChatGPT-powered AI chatbot intervention grounded in self-compassion theory and delivered over three weekly 20-min …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

An Evaluation Of Staff Training To Teach Implementation Of Functional Analysis Of Inappropriate Mealtime Behavior, Lauren Marie Lightner

Theses and Dissertations

Avoidant/Restrictive Food Intake Disorder (ARFID) along with other feeding disorders are prevalent in both neurotypical children along with children diagnosed with autism spectrum disorder (ASD) and other developmental disabilities. Children with feeding challenges often exhibit inappropriate mealtime behavior (IMB) to avoid consuming non-preferred foods. It is pertinent to determine the function of IMB in order to create an efficacious treatment; one such assessment is the functional analysis (Iwata et al. 1982/1994). Iwata et al. (2000) taught students how to implement a functional analysis of self-injurious behavior using behavioral skills training. Since the assessment’s development, it has been extended to various …

Exploring Public Perceptions Of Genetic Risk In Substance Use Disorders, Brooke A. Goodenow

All Dissertations

This dissertation examines genetic risk perception, with specific emphasis on substance use disorders (SUDs), through a collection of three manuscripts. The dissertation examines genetic risk perception for hereditary diseases in existing literature, describes a methodological framework for capturing genetic risk perception across social media discourse, and identifies themes and emotional tone associated with genetic risk perception for SUDs across two major social media platforms (X and Reddit).

Combined, these three manuscripts expand and support previous findings about genetic risk perception and its role in shaping health beliefs and associated behaviors. The dissertation findings reveal numerous similarities in genetic risk perception …

Balancing War And Peace In Taekwondo Athlete Development: A Multi-Criteria Coaching Decision Support Framework Using Leadership Scale For Sports And Fuzzy Ahp, King Harold A. Recto, Hazel Jade L. Antonio, Jhyrald Anthony P. Dalida

Electronics, Computer, and Communications Engineering Faculty Publications

Coaching effectiveness is frequently evaluated through competitive outcomes, with the assumption that coaching behaviors directly influence athlete performance. This study examined the relationship between perceived coaching behaviors and individual win percentage among collegiate Taekwondo athletes using the Leadership Scale for Sports (LSS). Descriptive statistics, correlation analysis, and regression analysis were conducted across five coaching dimensions: Training and Instruction, Democratic Behavior, Autocratic Behavior, Social Support, and Positive Feedback. Results showed that none of the coaching dimensions demonstrated a statistically significant relationship with win percentage. Although coaching behaviors did not significantly predict win percentage, the findings suggest that athlete development is shaped …

The Effect Of Cerebellar Transcranial Direct Current Stimulation On Anxiety, Shivangi Bhardwaj

All-Inclusive List of Electronic Theses and Dissertations

Anxiety is one of the most prevalent mental health disorders in the U.S. Individuals of all ages are affected by anxiety. Therefore, research into anxiety and its potential treatment has constantly been an area of interest. Newer approaches to managing anxiety include non-invasive stimulation techniques, such as Transcranial Direct Current Stimulation (tDCS), because of its accessibility and effectiveness. Past tDCS work typically focused on regions in the frontal lobe. However, tDCS over the cerebellum has not received as much attention compared to the cerebrum, despite recent work demonstrating cerebellar involvement in emotion processing. Thus, a better understanding of how cerebellar …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

Drinking Group Injunctive Norms: An Event-Level Examination, Karolina Kazlauskaite

Psychology Theses & Dissertations

College students are at increased risk for negative alcohol-related outcomes. Theoretical and empirical support suggest that peer groups play a crucial role in college student alcohol use, in part because they establish normative values and behaviors (i.e., norms) that members follow. Research indicates that those who identify more strongly with a group are more likely to embody that group’s values—particularly regarding drinking. Notably, injunctive norms, or perceptions of peer permissibility toward drinking, predict individual drinking outcomes, such that perceiving one’s peers as more approving confers additional risk for personal drinking. However, prior examinations of injunctive norms have not assessed perceptions …
