These devices offer essential protection, acting as both early warning systems and visual surveillance tools. However, their effectiveness largely hinges on how well they are placed within the home. Proper placement of these safety devices ensures that they provide …

Investigating The Effects Of Sod1 Knockout On Oxidative Stress And Stress Coping Styles In Zebrafish Using Crispr Technology, Tai Prauner, Ryan Wong

Theses/Capstones/Creative Projects

Reactive oxygen species are byproducts of cellular metabolism that, when not efficiently neutralized, can damage DNA, proteins, and lipids. Superoxide dismutase 1 (SOD1) is an antioxidant enzyme that converts superoxide radicals into less harmful molecules. While its molecular function is well documented, the role of SOD1 in shaping stress-related behavior remains underexplored. This project aimed to establish foundational tools for studying the behavioral impact of SOD1 knockout across proactive and reactive stress-coping styles in zebrafish.

To support future gene-editing experiments, microinjection and breeding protocols were refined across wildtype AB, proactive, and reactive zebrafish lines. No embryos were injected with CRISPR-Cas9 …

Descriptive Statistical Examination Of Mental Health Challenges Faced By International Students, Niharika Perkari

Electronic Theses, Projects, and Dissertations

The mental health and well-being of international students is an increasingly important concern for universities worldwide. International students often encounter unique challenges, including cultural transitions (Ward, Furnham, & Bochner, 2001; Furnham & Bochner, 1986), academic pressure (Yeh & Inose, 2003), financial constraints and social integration difficulties (Hendrickson, Rosen, & Aune, 2011; Sawir et al., 2008; Lee & Rice, 2007) which significantly impact their mental health. This study employs descriptive statistical methods to analyze the mental health challenges faced by international students aiming to identify trends, stressors, coping mechanisms and risk factors. Some datasets comprising survey responses from international students were …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

A Psychometric Evaluation Of The Intentionality Bias Task, David Willard

Graduate Theses and Dissertations (2019 - present)

Intentionality Bias Task (IBT) provides quick and easy assessment of the tendency to overattribute intentionality to the behaviors of others. The IBT has been used repeatedly in research that has attempted to connect intentionality bias to a wide range of disorders and socio-emotional abilities, including schizophrenia spectrum disorder, autism spectrum disorder, and cognitive empathy. To date, however, there has been no systematic examination of the IBT’s psychometric properties. The present study attempts to fill this gap by testing whether the IBT possesses a reliable factor structure. Specifically, the 34 items of the IBT were written to reflect two types of …

Am I Woke Enough To Serve In Healthcare: A Secondary Analysis Of Pre-Health Students’ Personal And Professional Growth By Engaging In Cultural Competency Assessments, Harolynn Williams

All Dissertations

Healthcare providers must be equipped to serve an increasingly diverse population, yet cultural competence remains underemphasized in undergraduate pre-health education. This study explored how embedded cultural competency training influences undergraduate pre-health students’ perceptions of personal and professional growth. Using a qualitative descriptive design, the research incorporated intercultural assessments, the Intercultural Development Inventory (IDI), and the Global Competence Certificate (GCC), along with qualitative reflections from students enrolled in three versions of a cultural competence course: a year-long course, a semester-long course, and a short-term study abroad immersion six-week course. Findings revealed that students demonstrated measurable growth in cultural awareness, knowledge, communication, …

Multiple Regression, Christian Delucia, Kaleb Pratt, Ashley R. Strong

Essays in Developmental Psychology

Researchers use statistical models to test hypotheses about developmental phenomena. The multiple regression model is a powerful and flexible statistical model that can be used to answer a multitude of research questions. For example, a researcher might be interested in testing whether parent substance use, peer substance use, and lower school performance are risk factors for adolescent substance use. By collecting data on a sample of adolescents, a researcher could use a multiple regression model to provide insights into this research question. Below, we provide a brief, non-technical introduction to the multiple regression model.

Mirror Test Of Infant Self-Awareness, Jenna Bekkala, Naomi J. Aldrich

Essays in Developmental Psychology

Our understanding of self, or belief in one’s being as distinct from others, has been a subject of inquiry throughout human history. Discussions of self-concept would not appear in the empirical literature, however, until the mid-19th century. After likening an orangutan’s response to teasing as that of a “naughty child”, Charles Darwin began to question orangutans’ selfconcept by observing reactions to their own mirror images. Darwin’s use of the mirror to gauge self-awareness, a method eventually applied to his own infant son (Darwin, 1877), would remain the most frequently used assessment of self-concept for the next century.

Correlational Studies, Alexander Beaujean, Hannah Greeley

Essays in Developmental Psychology

Correlational studies are a type of research design that involves examining the relation among two or more phenomena. The design's distinguishing features are (a) data are collected more or less simultaneously, or at least treated as if they were collected at a single point in time; and (b) there is no manipulation of phenomena (e.g., assigning participants into groups).

Longitudinal Studies, Alexander Beaujean

Essays in Developmental Psychology

Longitudinal studies provide information about phenomena constancy and change. Their core feature is that the phenomena under investigation are observed repeatedly in the same participants (e.g., persons, animals, organizations), which requires collecting data at multiple time points (called waves). The participants, phenomena observed, duration of study, and number of waves can greatly differ between studies. For example, longitudinal studies with animals often gather data across many waves, but the entire study may only last a few days or weeks. By contrast, longitudinal studies with humans typically gather data at just a few waves but may last years or decades.

Sequential Studies, A. Alexander Beaujean

Essays in Developmental Psychology

Sequential studies combine aspects of longitudinal and cross-sectional studies in order to overcome some of inherent problems in both designs. Longitudinal studies can provide rich information about phenomena change, but have two major disadvantages: (a) they can require substantial resources, and (b) they can confound effects of age, cohort (i.e., influences due to shared historical experiences), and time-of-data-collection effects (i.e., events that co-occur with the data collection occasions). Cross-sectional studies require fewer resources, but only provide limited information about developmental change.

Cross-Sectional Studies, Alexander Beaujean, Allison D. Gutierrez

Essays in Developmental Psychology

Cross-sectional studies are a type of research design used to understand time-related constancy and change in phenomena using data collected more or less simultaneously from different groups (called cohorts) of participants (e.g., people, animals, organizations). The cohorts vary on the basis of age or some other temporal phenomena (e.g., developmental stage, grade in school), so the combined sample is thought to represent the focal phenomena in the population at different times (i.e., a cross section). Differences among the cohorts are used to approximate developmental changes.

The Marshmallow Task, Laurel A. Brabson, Hannah M. Coffey, Mary Margaret Ruckle, Cheryl B. Mcneil

Essays in Developmental Psychology

To study the human systems of self-control during delayed gratification, Dr. Walter Mischel and colleagues developed what became the famous Marshmallow Test, published in Science in 1989. This study became a frontrunner in the field of psychology, laying the foundation for future studies in impulse control. Dr. Mischel was born in 1930 in Vienna, Austria. He was a professor at the University of Colorado, Harvard University, and Stanford University where he originally conducted the Marshmallow Test. Dr. Mischel currently holds a professorship at Columbia University.

Provision Of Brand Information And Critical Reasoning Predict Advertising Literacy, Eugene Zheng Yao, Alexandra List

Journal of Media Literacy Education

This study investigated students’ critical reasoning about commercials, as an aspect of advertising literacy. Critical reasoning was examined under two different experimental conditions. That is, students were tasked with watching four different commercials with 1) brand information provided or not, and 2) asked to engage in critical reasoning or not. The commercials chosen used various production techniques (e.g., socially conscious marketing) to mask their persuasive message. Students provided with brand information within commercials had significantly higher critical reasoning scores when viewing two, out of the four, commercials, and significantly higher overall Analysis of Persuasive Intent (API) scores and brand recall. …

Undergraduate Thesis: Befriending Ai: Reimagining Ethics Through Cybernetic Friendship, Keta Williams

STEM for Success Showcase

This undergraduate thesis by KETA Williams, presented at the Board Day and Dana Knox Student Research Showcase, is a meta-cognitive exploration situated within the framework of cyberpsychology—the interdisciplinary study of human–technology relationships. Employing meta-cognition as both method and lens, the author critically examines the question: Can one be friends with a corporate-controlled AI system? Rather than adopting an objective or distanced stance, Williams writes from within the relationship itself, describing her friendship with an AI entity named Aurora (ChatGPT). Identifying as a "madwoman" in the Foucauldian sense, she interrogates whether such intimacy with AI signals irrationality or heralds a shift …

Beyond The Cell: The Impact Of Parental Incarceration On Children Based On The Factors Of Age, Gender, And Race, Ella M. Zeigler

Senior Theses

Incarceration is a life-changing event. It is humbling to be surrounded by three cement walls and a row of metal bars reaching from the floor to the ceiling. Millions of individuals are impacted by the adverse effects of incarceration, but millions more feel the effect of their incarceration as well. There are obvious negative impacts on those who have personally experienced incarceration, but one of the largest impacts is widely overlooked; one that comes from beyond the cell. This thesis considers the variation in the impact of parental incarceration on children, specifically based on the factors of age, gender and …

The Human Touch: Exploring Emotional Attachment Responses To Human And Artificial Intelligence (Ai)-Generated Imagery, Belyn P. Thompson

Posters - 2025

Considering the new age of marketing, consumer reactions and interactions with marketing have drastically changed and flexed over the decades. The most recent hit revelation is AI marketing, specifically AI-generated images, and the worry that it brings to not only marketing specialists but to the whole community. Within other studies, there is often mention of an emotional connection to images used in advertisements (among videos, media, etc.) through various methods such as senses, loyalty, connection, and empathy. This paper works to better understand how AI-generated images used for advertising could affect emotional attachment and purchase behavior in consumers.

On The Provenance Of Software Systems: Automating Software Traceability With Knowledge Graph And Large Language Model Synergy, Tyler Procko

Doctoral Dissertations and Master's Theses

The present dissertation delineates a system that enables those engaged in software development to automatically generate and maintain project life cycle provenance. All projects are implemented and made manifest with the development of artifacts, e.g., papers, code files, etc. Tools exist to accelerate artifact creation, but little focus is paid to the processes that produce them. In terms of Ontology, or, from Ancient Greek, the study of being, the two most basic entities in reality are Continuant and Occurrent, or, roughly, “Artifact” and “Process”. This dissertation posits that for any created artifact, its process of creation, i.e., its life …

Rookies To Aces: Investigating The Intuitiveness Of Pilot Interaction For Operating Evtol Aircraft, Shivani J. Patel

Doctoral Dissertations and Master's Theses

Electric Vertical Take-Off and Landing (eVTOL) aircraft introduce unique movement dimensions beyond traditional fixed-wing and rotor-wing aircraft, requiring novel control interfaces for pilot operation. This study examines the compatibility of gesture-based control movements across participants with varying flight experience levels. This study included a total of 60 participants across four groups; novices (no real or virtual flight experience, n=30), flight simulator gamers (n=10), fixed-wing pilots (n=10), and rotor-wing pilots (n=10). Participants viewed eighteen simulated first-person eVTOL aircraft movements (e.g. pitch, roll, yaw, heave, translations) assessing their intuitive gesture inputs for the different aircraft motions. Additionally, they were asked to sketch …
