Interpreting American Sign Language: A Literature Review Of Assistive Technologies, Natalie Louise Paradiso, Emma Grace Kochenderfer

Student Scholar Symposium Abstracts and Posters

American Sign Language (ASL) is a visually elaborate, spatially oriented linguistic methodology that relies on combinations of hand movements, body positioning, facial expressions, and motion/spatial perception, aspects of which make interpretation difficult for automated machine recognition. Current assistive technology approaches to ASL interpretation are generally within the categories of computer vision models (including deep learning, multi-focus image fusion, and keypoint tracking) and wearable, multimodal/sensor-based approaches (such as smart glasses and inertial-sensor gloves). Within controlled environments, computer vision models perform well. However, when applied to conditions such as non-manual signs/features, signer variability, and rapid assimilation, they falter in processing all aspects …

Alone And Radicalized: The Hidden Link Between Isolationism And Political Violence, Zaina Siddiqui

Student Scholar Symposium Abstracts and Posters

As some socially isolated individuals come to view political violence as legitimate, what exactly draws the line towards political extremism? My findings examine the relationship between loneliness, social marginalization, and support for political violence through psychological theories on radicalization. Using Chapman University’s American Fear Survey Wave 11, I examined the correlation between isolationism and a sense of belonging, with the latter leading to support for political violence and extremism. The project contributes to research on political extremism by focusing on loneliness as a loss of belonging and personal significance rather than on ideology or pathology alone. In my research, I …

Personality Meets Possibility: Exploring Cognitive Engagement For Older Adults In A Changing World, Kalvry A. Cooper

All Theses

Engagement in cognitively stimulating activities (CSAs) is critical for maintaining cognitive health in older adults. While existing research has examined the benefits of CSAs, less is known about how factors such as personality traits, education, and technology proficiency influence engagement, especially during the COVID-19 pandemic. This study aims to explore older adults' participation in online versus in-person CSAs during the pandemic and identify key predictors of engagement. Using secondary data from the EFIT and ENACT studies, this research investigates how variables like marital status, education, personality traits, and mobile device proficiency shape older adults' decisions to engage in online or …

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 …

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 …

Evaluating The Psychometric Validity Of Science Curiosity, Brooke Simila

Graduate Theses and Dissertations (2019 - present)

As political polarization and mass distrust in scientific consensus increases, psychologists have sought to understand individual differences that contribute to polarized political and scientific reasoning. One emerging concept in this area is science curiosity (SC), the disposition to seek and engage with scientific information for personal gratification (Kahan et al., 2017). A handful of studies have identified SC as an offsetting variable in politically motivated reasoning (Motta et al., 2021). However, the psychometric structure of SC remains underexplored; it is unclear whether SC represents a distinctive, unidimensional disposition or merely a manifestation of general curiosity traits. The purpose of this …

Narcissism And Eyewitness Identification, Haley M. Hearn

Graduate Theses and Dissertations (2019 - present)

According to the Innocence Project, 69% of individuals exonerated by DNA evidence were initially found guilty due to an eyewitness misidentification (Innocence Project, n.d.-a). A way that investigators attempt to prevent misidentification is by assessing how confident eyewitnesses are in their identifications. There is a large body of research suggesting that these confidence estimates can, in many instances, operate as reliable barometers of accuracy. However, what if an eyewitness is overconfident? Narcissism is a personality trait characterized by overconfidence. If a narcissistic eyewitness reports confidence in their identification of a suspect, should this report be trusted? Two studies were conducted …

Exploring The Experiences Of Adult Children Of Parents With Addiction: A Qualitative Support Group Approach, Brooke Stanton

Undergraduate Honors Capstone Projects

Adult children of parents with addiction often grow up having to navigate emotional instability, inconsistent caregiving, and long-term relational impacts that continue into adulthood. Many individuals report limited access to supportive care and spaces where they can share their stories. This capstone project addresses the gap by designing and facilitating a support group specifically for adult children of parents to build connection and healing. Through this qualitative study, participant feedback, and analysis, this project examines how structured peer support can create meaningful change for this population. The following paper outlines the development of the group, the theoretical foundations that guided …

Timing Of Parental Divorce And Spiritual Behavior In Young Adulthood: A Quantitative Study, Marcus A. North

Electronic Theses and Dissertations

Background: While the literature on divorce and its impacts on children currently is quite robust, additional information can be contributed to specific factors that impact spiritual outcomes later in life. This research study sought to investigate the relationship between a child’s age at the time of their parents’ divorce and their subsequent spiritual behavior in young adulthood.

Methods: Cross-sectional survey was created, utilizing two previously validated instruments: Daily Spiritual Experiences Scale (DSES) and the Centrality of Religiosity Scale (CRS-15). The survey was administered online through Qualtrics software; participants were recruited through non-random purposive sampling, as well as participant snowballing.

Results: …

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. …

Rationale Behind Subtitle Usage In Non-Deaf Individuals Across Various Platforms, Jenna E. Kasselman

Honors Theses

Subtitles have a long history with the medium of audiovisual communication. Options for viewing media with added text have only increased with technology, and in the age of the internet, more accessible material is available than ever before. While numerous studies have been conducted on the beneficial effects of subtitles for both the deaf and the hearing, little academic publication has been done on the rates of subtitle usage, reasons for usage, and how that usage differs based on what media is being viewed. The current study examines subtitle usage, frequency of subtitle usage, and reasoning for that usage divided …

Starting With Story, Not Symptom: Narrative Collapse And Cultural Repair In Appalachia, Wayne Coombs Ph.D.

Journal of Appalachian Health

Appalachia’s opioid crisis reflects uneven burdens, especially in distressed coalfield counties, and it cannot be solved by symptom tracking alone. This commentary argues for a narrative shift, starting with story and cultural repair alongside clinical care. Narrative collapse is defined here as the loss of shared, dependable public meaning across groups, not the absence of storytelling in families, churches, and recovery circles. Trauma science suggests that chronic threat reshapes nervous systems across generations, making safety a prerequisite for renewed trust. Drawing on narrative identity research, the piece proposes peer story work as infrastructure that can reduce shame, support treatment engagement, …

A Proposal To Examine Naturally Occurring Mindfulness And Correctional Officer Stress And Burnout, Anthony M. Nasrallah

Undergraduate Theses

Correctional officers (COs) work in institutions characterized by high interpersonal demand, safety risk, and organizational complexity; as a result, they experience elevated rates of occupational stress, burnout, and mental-health disorders relative to the general workforce. At the same time, research in allied helping professions demonstrates that mindfulness and related contemplative practices can reduce stress and improve emotion regulation and well-being. However, little is known about whether COs’ own, pre-existing informal mindfulness practices are associated with lower on-the-job stress or burnout rather than formal training courses. This review integrates findings from qualitative studies, quantitative analyses, and systematic reviews to show what …

Ai-Human Relationship Experiences, Ari Rad

SACAD: Scholarly Activities

Recent scholarly research regarding “human–chatbot relationships

(HCRs)” demonstrates that users often report having developed

meaningful connections with artificial intelligence. Although the

initial exposure to AI chatbots is seemingly predicated on users’

“curiosity,” the data suggest that “loneliness” is a precursor that

maintains the use of chatbots (Skjuve et al., 2022; Skjuve et al.,

2023). A cross-sectional mixed-method survey study demonstrated

that “loneliness” and “lower perceived social support” are among the

initiators of the use of chatbots for companionship (Herbener &

Damholdt, 2025).

The unique characteristics of these AI companions (e.g., being

socially safe, nonjudgmental, and always available) have brought

forth …

The Effects Of Low Stimulating Music Vs. High Stimulating Music On Visual And Auditory Reflexes In Young Adults, Monabelle Elbayeh, Vania Galindo, Ria Modi, Gianna Montelongo

Posters - 2026

This study investigates the effects of high-stimulating versus low-stimulating music exposure on human reflexes, specifically examining how different levels of auditory stimulation influence reaction time. Music is known to impact cognitive and motor performance, but its direct effect on reflex responses remains less understood. In this experiment, participants are exposed to high-stimulating music and low-stimulating music in separate trials, with reflexes measured before and after each condition using visual and auditory tests in the LabScribe program. It is hypothesized that after listening to high-stimulating music for five minutes, individuals will demonstrate shorter reaction times compared to after listening to low-stimulating …

Enhancing Undergraduate Learning In Physics: The Effects Of Ai-Assisted And Ai-Guided Instruction On Knowledge, Self-Efficacy, And Satisfaction, Stephen Woods

Doctoral Dissertations and Master's Theses

Generative artificial intelligence (AI) tools such as large language models are increasingly used for self-directed learning, yet there is limited experimental evidence on whether they improve learning outcomes and whether theory-informed guidance adds value beyond AI use alone. Prior literature suggests that effective learning depends not only on access to information, but also on how instruction supports attention, working memory, long-term memory, and cognitive load, while also fostering motivational processes such as self-efficacy. Individual differences such as Need for Cognition may also shape how learners engage with cognitively demanding instructional tools such as AI.

The present study examined how different …

Executive Functioning In Schizophrenia Using A Novel Virtual Reality-Simulated Workplace: Validity, Test-Retest Reliability, And Links To Competitive Employment, Ernest Marek Tyburski, Ewa Zawadzka, Adrianna Bober, Ewa Karabanowicz, Piotr Podwalski, Jerzy Samochowiec, Anna Michalczyk, Shane T. Mueller, Michał Szelepajło, Błażej Misiak, Monika Folkierska-Żukowska, Monika Mak, Michał Harciarek, Krzysztof Wietrzyński, Ashok Jansari

Michigan Tech Publications

Virtual reality offers a promising avenue for the assessment of executive functioning in complex workplace environments. However, its use in schizophrenia remains limited. For that reason, we investigated the validity and test-retest reliability of the Jansari assessment of Executive Functions (JEF©) in individuals with schizophrenia and its associations with competitive employment. A total of 69 participants with schizophrenia and 67 healthy controls completed JEF© and standard tests. A subsample of 58 patients was retested after an 8-week interval. Individuals with schizophrenia performed more poorly than controls on JEF© (p <  0.001) and standard tests (p <  0.05). JEF© scores correlated with standard measures (p <  0.05), except inhibition tests, and with clinician-report of everyday problems (p <  0.001). Total score showed a good test-retest reliability and the practice adjusted RCI indicated 87.9% of patients remained stable over 8 weeks. In logistic regression, higher JEF© total score significantly predicted competitive employment after adjusting for age (p = 0.004) and remained significant when …

The Illusion Of Causality In Llms: A Developmentally Grounded Analysis Of Semantic Scaffolding And Benchmark–Capability Mismatches, Daisuke Akiba

Publications and Research

Recent benchmarks increasingly report that large language models (LLMs) exhibit human-like causal reasoning abilities, including counterfactual inference and intervention planning. However, many such evaluations rely on domains that are heavily represented in training data and embed strong semantic cues, raising the possibility that apparent causal competence may reflect semantic pattern recombination rather than structure-sensitive causal reasoning. Drawing on human developmental theories of causal induction, this perspective argues that genuine causal understanding requires robustness to novelty and reliance on conditional structure rather than semantic familiarity. To illustrate the testability of this claim, the paper includes a pilot demonstration using synthetic causal …

A Conceptualization Of The Teaching Practice Of Building, Shari L. Stockero, Blake E. Peterson, Keith R. Leatham, Laura R. Van Zoest

Michigan Tech Publications

In this theoretical paper, we present a conceptualization of the teaching practice of building—a teaching practice that takes advantage of high-leverage student contributions we call Mathematical Opportunities in Student Thinking (MOSTs). Specifying this complex teaching practice is important because it provides the detail needed for mathematics education researchers to study the nuances of teachers’ in-the-moment use of student thinking and for mathematics teacher educators to support teachers in developing such use. We describe key aspects and teacher actions associated with the four elements of building: Establish, Grapple Toss, Conduct, and Make Explicit. Throughout the paper we compare and contrast this …
