Explaining The Relationship Between Trust And Dependence: The Unexplored Interactive Effect Of Workload And Individual Differences In Cognitive Abilities, Connie Ku

All Dissertations

Trust is often treated as a key driver of automation use, with the assumption that higher trust leads to greater dependence. Yet findings have been inconsistent, with trust-dependence correlations ranging from negative to positive, and some studies finding no relationship at all. One factor that may explain this inconsistency is mental workload, which has received little attention as a moderator. This research examined whether workload moderates the trust-dependence relationship, and whether attention control, working memory, and fluid intelligence further shape this moderation.

Study 1 used a web-based AI chatbot quiz to test whether workload moderated the trust-dependence relationship. Trust was …

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 …

Improving Urban Search And Rescue Team Coordination Through Adaptive Context Awareness, Daniel Reyes Duran

Doctoral Dissertations and Master's Theses

Modern multi-agent Urban Search and Rescue (USAR) operations heavily rely on mobile geospatial Common Operating Pictures (COPs) to maintain team coordination and Situational Awareness (SA). However, the proliferation of high-frequency sensor telemetry at the tactical edge has introduced a data saturation paradox challenge: while information theoretically drives informed decision-making, unmanaged data surges induce increased operator cognitive overload and alert fatigue on mobile End-User Devices (EUDs), while downstream data-broadcasting models inherently strain edge processing and viewport environments.

To resolve these constraints, this dissertation presents a context-aware Value of Information (VoI) data-management framework integrated directly with a custom, event-driven Android Team Awareness …

National Journal of Occupational Health and Safety

Sewing workers in the garment industry are at high risk of developing non-ergonomic working postures that may lead to musculoskeletal disorders (MSDs), due to prolonged static postures and the use of chairs that are not compatible with workers’ anthropometry. Preliminary surveys indicated complaints of pain in the back, neck, and waist (90%), shoulders and forearms (85%), and upper arms (80%). An ergonomic intervention that can be implemented is the use of ergonomic chairs. This study aims to analyze the effect of using SIGO (Seat Improvement for Garment Operators) as an ergonomic intervention on improving working posture and reducing MSD complaints …

Investigating The Effect Of Gendered Seating Proximity On Classroom Success For Female Engineering Students, Cassandra Savukinas, Kayla D. Taylor

Student Research Symposium (SRS)

This research will examine how aspects of an undergraduate learning environment, specifically seating choices and spatial positioning of female-presenting students, affects classroom success for female-identifying engineering students. Existing literature highlights the underrepresentation of women in engineering and gender disparities in STEM education, which persist from elementary school through higher education. Single-sex K-12 school environments report enhanced academic performance and self-esteem for female students; however, few studies explore gendered seating proximity in coeducational, male-dominated undergraduate STEM courses. Investigating how gendered seating dynamics impact components of classroom success can provide insight into improving retention and engagement for female-identifying students in engineering majors. …

Are Single-Pilot Operations An Advantage Or A Disadvantage?, Ezgi Berte Erme

Conversely, the perceived disadvantages include diminished lack of situational awareness, lack of communication …

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 …

The following paper outlines the development of the group, the theoretical foundations that guided …

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 …

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 …

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

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. …
