Subjective Time Estimation In Rats: Seconds To Minutes, Alissa Christensen

Holster Scholar Projects

Time estimation is important for survival. Importantly, time estimation is subjective, influenced by a variety of factors.

We used a temporal bisection task (Church & Deluty, 1977) to determine the degree to which a rat “feels” a stimulus is long/short in reference to predetermined anchor durations.

Animals were first trained to respond differently to a short (3s) and long (6s) duration light-cue. This was followed by intermediate duration probes (averaging 4.5s). Most animals treated the intermediate intervals as long. The function varied, some showing a more linear response while others a step function.

The second phase examines longer time estimation, …

Building The Mental Golden Dome: Arming The Joint Force For Defensive Cognitive Warfare, James Davitch

Joint Force Quarterly

Modern conflict increasingly hinges on mental strength, yet current military thinking lacks a clear defense for the mind. This article introduces a vital new concept: protecting military personnel from an adversary's attempts to distort their perceptions, disorient their judgment, and degrade their decision-making. Building on established research into behavioral psychology, the essay integrates this defense into existing military functions, proposing practical steps. It offers a precise explanation of this protective strategy, suggests pre-deployment exercises for joint personnel, and outlines ways to measure effectiveness even under pressure. A detailed, multi-year plan describes how to update joint doctrine, create training programs, and …

HCA Healthcare Journal of Medicine

Background

In this pilot study, we examined psychological impacts of colorectal cancer (CRC), focusing on cancer-related posttraumatic stress disorder (CR-PTSD) symptoms, posttraumatic growth (PTG), and their relationship with coping strategies in surgically treated CRC patients.

Methods

This prospective pre- and postoperative pilot study assessed CRC patients at 2 time points, pre- and postoperative. Psychological symptoms were evaluated using the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5) and the PTG Inventory Short Form (PTGI-SF). Coping strategies were assessed using the Brief Coping Orientation to Problems Experienced (COPE) instrument. Changes in CR-PTSD, PTG, and coping …

The Cost Of Caring: Understanding Compassion Fatigue In First Responders, Jonathon O. Santiago

Master of Arts in Human Services

First responders are regularly exposed to trauma, crisis, death, injury, and human suffering, which may contribute to compassion fatigue. This capstone examined compassion fatigue among law enforcement officers, emergency medical services personnel, firefighters, and other emergency-service professionals. The paper reviewed peer-reviewed research on symptomatology, occupational risk factors, protective factors, compassion satisfaction, emotional labor, stigma, help-seeking barriers, and organizational influences. Attention was given to the overlap between compassion fatigue, burnout, secondary traumatic stress, and vicarious trauma, as inconsistent definitions may make the issue harder to identify, measure, and address. The research also explored how repeated trauma exposure, confidentiality concerns, workplace culture, …

Trust is essential in every workplace, but conflicts, mistakes, and broken promises are inevitable. This project develops an experiential classroom exercise in which students diagnose workplace trust violations, examine the perspectives and emotions of both parties, and practice selecting and communicating evidence-based reparative actions. The exercise translates organizational behavior research into a practical learning experience that develops not only managerial competence but also the character, empathy, and relational wisdom needed to build healthy organizations and promote human flourishing.

I gratefully acknowledge peer review feedback on this project, and I am accountable for writing of this product without generative AI and …

A Poetic Call For And A Reflection And Commentary On Clarity, Understanding, Hope, Courage, And Compassion, Carroy U. Ferguson

Psychology Faculty Publication Series

Finding a published poem I had written as a teenager, titled “The Heavens Weep.” this article uses that poem as the basis for a commentary that reflects on the state of the world today (2026),  As a commentary, the article uses the poetic and metaphoric words in the poem as a relevant "reality check" for what is still going on today.  In essence, the commentary is about a call for Clarity, Understanding, Hope, Courage, and Compassion, or what I call Archetypal Energies, Higher Vibrational Energies that operate deep within our individual and collective psyches to creatively urge us to "see" …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

Testing P300-Based Biometric Authentication Paradigms, Jordan Razzak

Electronic Theses and Dissertations

Bench research suggests that P300 amplitude is greater in response to self-relevant stimuli compared to familiar stimuli. This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …

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 …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Domestic Travelers: Transparent Machines, Hollow Bodies, Hanyi Wang

Masters Theses

Digitization is not a modern invention. Derived from the concept of fingers, this mindset of packing information into quantifiable, interchangeable units sounds mechanical, yet eerily physical. Try to imagine: a ghostly hand with millions of fingers with the same length, likeness, and function. Under the worldview of Digital Narrative, we live in a digital simulation: everything is representable with quantifiable units, fluid across media. Yet under this spectacle of convenient abundance, something is missing. The Unknowables are replaced with arbitrary symbols, while the Uncategorizables are omitted. This is a framework that cannot accommodate human subtleties and complexities. One needs to …

Reading Exercise (You Are The Hero): Dedicated To The Providence River Under The Mall, 02.17.2026, Deborah Fischer

Masters Theses

This play uses the performative potential of guilt, forgiveness, and self-help techniques as a catalyst for a new dynamic, one in which the pursuit of a false narrative, along with the structures it generates, becomes more real than reality itself. It employs “bad acting” and the practice of cold reading to stage a series of acts that function as an entry point into one’s own psyche, leveraging the peripheral space around familiar actions to allow chance, free will, and the experience of “real time” to temporarily come into effect. PLAYER 1: The bad actor is the most utopian one. CLOWN: …

Emotional Working Memory Across The Visualization Spectrum, Jae Fast

Undergraduate Honors Theses

In 2015, the term “aphantasia” was coined to describe a small group of individuals who lack the ability to voluntarily produce visual mental imagery. This caused a rising interest in aphantasia and its associated neural, behavioral, cognitive, and emotional features. Understanding the role of visual mental imagery in both emotional and cognitive processes, it is reasonable to question whether aphantasia may result in importantly unique experiences that may require improved therapeutic practices to account for these differences. Previous studies have found that aphantasics experience reduced emotional responses to recalled emotional events, reduced affective processing, poor autobiographical memory, and other cognitive …

Some Equivalence Statements Are Metaphors, Malik A. Terry

Theses and Dissertations

Metaphors work best when topic and vehicle come from different domains. Glucksberg (2011) observed that same-domain statements ( "Cats are dogs") lack metaphorical interpretations, and Experiments 1 and 2 confirmed this. Prasada (in press) proposed that minority framing ( "Some cats are dogs") enables such metaphors. Experiment 3 confirmed this.

Between Chronicle And Legend: A Two-Scene Environment And Visual Effects Examination Of Physical Accuracy And Emotional Exaggeration On The Honey Creek Bridge Collapse, Alison R. Gaddy

All Theses

This thesis explores how truth and dramatization intersect in digital storytelling by comparing realistic and stylized simulations of the Honey Creek bridge collapse within the context of the Kate Shelley animated short. At the core of storytelling lies a tension between factual accuracy and dramatic stylization. We investigate that tension by examining how narrative truth is conveyed, distorted, or enhanced through visual dramatization by focusing on the psychology of audience perception and the motivations behind creative embellishment. The practical contribution of this research is the development of two distinct digital scene setups depicting the same Honey Creek bridge collapse event. …

Somatosensory Cortex Responses To Illusory Touch In A Visual-Tactile Integration Task, Aditi Surendra Pawar

Dissertations, Theses, and Capstone Projects

Perceptual illusions arising from multisensory integration reveal how the brain constructs subjective experience from sensory input, and provide a powerful means of allowing the investigation of neural processes that track perceptual interpretation rather than physical stimulation alone. While visual illusions induced by auditory or tactile stimuli have been fairly well studied, the neural mechanisms underlying visually-induced illusory touch remain unclear. This study investigated whether illusory tactile perception engages the somatosensory cortex in a manner similar to veridical touch. Twenty healthy adults participated in an event-related functional magnetic resonance imaging (fMRI) study while performing a tactile numerosity judgment task. Each trial …

Emotional And Social Perception In Hearing And Deaf Individuals, Julie Klenotic

Williams Honors College, Honors Research Projects

This study will compare the differences in emotional recognition and social dynamic understanding between hearing and Deaf people. I will investigate the differences in these areas between hearing and Deaf individuals, as well as the role American Sign Language use has in performance. It will utilize point light walkers which will display the emotions happy, angry, sad, and neutral. Participants will be asked which emotion is being displayed based on the presented gait of the point light walker. Second, they will view 15 videos from the Interpersonal Perception Task without audio. The questions from the IPT 15 will then be …

Creativity In A Flash: Exploring The Perceived Therapeutic Effects Of Combining Creative Arts Therapies And Flash Technique, Celia J. Gagnon

Art Therapy | Doctoral Dissertations

Since the onset of the COVID-19 pandemic, research has revealed a significant strain on mental healthcare systems and healthcare professionals. Concurrently, there has been a rapid escalation in the prevalence of anxiety, depression, loneliness, and adolescent suicide rates, all of which have reached critical levels (World Health Organization, 2025; World Health Organization, 2022; Institute for Health Metrics and Evaluation, 2025; American Psychiatric Association, 2024). Post-pandemic, these statistics continue to rise across all nations and socioeconomic groups (WHO, 2025). Consequently, there is an urgent need to intensify research that supports the enhancement of mental health services globally (Institute for Health Metrics …

Exploring Students' Perceptions Of Active Learning Practices And Their Role In Critical Thinking Development In Undergraduate Biology Education, Kwame Kyeremah

All Master's Theses

As the global landscape becomes increasingly complex and undergoes more rapid changes than ever before, critical thinking has become an indispensable skill for addressing challenges in society, science, and the workplace. Despite its widespread adoption in undergraduate STEM education, active learning remains poorly understood from the student's perspective. This study investigated how undergraduate biology students perceived active learning in a ten-week biostatistics course (BIOL 213) at Central Washington University, and whether those perceptions aligned with critical thinking gains measured by the California Critical Thinking Skills Test with Numeracy (CCTST-N). A convergent mixed-methods design integrated student perception and mindset survey data …

An Examination Of Speech Motor Control And Auditory Processing In Attention Deficit Hyperactivity Disorder (Adhd), Rita Bishai

Theses and Dissertations (Comprehensive)

Fluent speech production is achieved through a relative weighting of feedback and feedforward motor control systems. These systems are thought to be responsible for the online correction of vocal errors and initiating speech, respectively. The relative weighting of these motor control systems has been shown to differ under conditions of high attentional load and across individual differences in sensory acuity. However, research has yet to examine speech motor control in a population with clinical attentional and sensory processing differences, such as those with Attention-Deficit Hyperactivity Disorder (ADHD). The studies in this thesis aimed to examine how ADHD traits relate to …

From Meaning To Memory: Assessing The Capacity And Representational Structure Of Visual Working Memory With Meaningful Stimuli, Yong Hoon Chung

Dartmouth College Ph.D Dissertations

Visual working memory is thought to be strictly limited. Yet we remember meaningful, real-world objects better than abstract stimuli. Here I show that this advantage arises from the semantic structure of meaningful objects, not their perceptual features alone, and that it extends even to memory for associated features such as color. In the brain, meaningful objects elicit greater and more distributed delay activity, consistent with the recruitment of higher-level neural processes during maintenance. I propose that semantic knowledge adds representational dimensions that make items more distinctive, and that these dimensions are organized hierarchically with lower-level visual features. These findings recast …

How What We Feel Is Associated With What We Hear Early In Development: The Role Of Vision In Audio-Tactile Association, Shibo Cao

Graduate Doctoral Dissertations

Sound-shape correspondences, also known as bouba-kiki effect, is the preferential mapping of nonsense sound like “baluma” to rounded abstract shapes while mapping nonsense sound like “takete” to spiky abstract shapes. Such association was seen for auditory and visual stimuli (AV), and auditory and tactile stimuli, which are touched but not seen (AT). Literature comparing typically-developing and early-blind adults showed AT association differ as a function of level of visual experience, and similar finding was also found comparing typically-developing adult and children. Specifically, typically-developing younger children benefited from prior AV experience of abstract shapes and nonsense sounds. While these findings suggest …

Ctrl + Alt + Inner Speech: A Verbal–Cognitive Scaffold (Vcs) Model Of Pathways To Computational Thinking, Daisuke Akiba

Publications and Research

This theoretical paper introduces the Verbal–Cognitive Scaffold (VCS) Model, a cognitively inclusive framework which proposes the cognitive architectures underlying computational thinking (CT). Moving beyond monolithic theories of cognition (e.g., executive-function and metacognitive control models), the VCS Model posits inner speech (InSp) as the predominant cognitive pathway supporting CT operations in neurotypical populations. Synthesizing interdisciplinary scholarship across cognitive science, computational theory, neurodiversity research, and others, this framework articulates distinct mechanisms through which InSp supports CT. The model specifies four primary pathways linking InSp to CT components: verbal working memory supporting decomposition, symbolic representation facilitating pattern recognition and abstraction, sequential processing enabling …

Physiological Response To Concealed Information In A Mock-Crime Paradigm​, Ezra Koenigsberg, Tamya Mchenry, Jasmine Manzana, Taylor Powell, Samantha Jackson

Science University Research Symposium (SURS)

The Concealed Information Test (CIT), based on Lykken’s guilty knowledge framework, measures physiological responses when individuals recognize crime-related details compared to neutral alternatives. Previous studies show that variations in stimulus presentation enhance the CIT’s accuracy, especially through changes in electrodermal activity and heart rate. However, few studies have tested whether a Qualtrics-based mock-crime version of the CIT can replicate these physiological patterns. This study addresses that gap by adapting the CIT for a digital research environment. The goal is to determine whether participants show greater physiological arousal—measured through skin conductance, heart rate, and respiration—when exposed to crime-related “critical” stimuli compared …

Access Denied: An Argument Against King’S Propositional Access Principle, Jesse Fitts

Philosophy Faculty Research

Accounts of propositions face a problem that originates in the ontology of numbers: If propositions are abstract and causally isolated, then it’s unclear how agents cognitively access them. Jeff King presents a solution to this problem for his theory of propositions. King’s solution follows from a more general principle of cognitive access, which this paper challenges.

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray

Journal of Humanities and Social Sciences

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

Trauma In The Middle Ages: The Viking Experience Of Trauma Through Saga, Kagan L. Vogt

University Honors Theses

Trauma is a fundamental part of human experience and the ways in which human beings experience trauma differs drastically depending on the time and culture represented. Research on trauma in the Middle Ages does exist, however, often offers windows into very narrow intersections within the study of historical trauma. Other cultures and particularly oral traditions lack the same attention from scholars in trauma. The specific experience of Vikings as referenced in the oral tradition of sagas offers a unique window into the traumatic experience of Vikings as well as how they responded to trauma. This unique response to trauma is …
