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, …

Hybrid Deep (Cnn-Bilstm) Intrusion Detection For Defense And Mission-Critical Networks, Corey A Cheng, Jermaine Anim-Addo, Asma Jakir Hussain, Zion O Smith-Fox, Sanjay Goel, Yuksel Celik

Military Cyber Affairs

This article examines how hybrid deep learning can strengthen intrusion detection for military and defense networks. Using the CSE-CIC-IDS2018 dataset, the study evaluates a CNN-BiLSTM model designed to detect benign traffic and multiple attack categories, including DDoS, DoS, botnet, brute-force, web attack, and infiltration activity. The model achieved strong multi-class detection performance, with 0.9893 accuracy and 0.9979 ROC-AUC. The findings suggest that AI-supported intrusion detection can improve cyber defense operations, analyst triage, and protection of mission-critical networks.

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 …

Retrieval Information From Working Memory: The Output Gating Framework Perspective And Its Underlying Processes, Chen Tiferet-Dweck

Dissertations, Theses, and Capstone Projects

Working memory (WM) keeps information accessible and available for further processing. However, not all the information we maintain in WM is behaviorally relevant at any given moment. To act effectively, we must dynamically control which memory representations are accessed to support ongoing goal-directed behavior. While the mechanisms underlying the selection of single items from WM access are comparatively well-studied, less is known about the principles governing multi-item access. Existing models of WM access imply that selecting multiple items should take longer and be more error-prone than single-item access. Yet, paradoxically, prior studies have shown that retrieving all items in WM …

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, …

The Moderating Effect Of Facial Recognition Ability On The Post-Identification Feedback Effect, Benjamin Martell

Student Theses

Abstract

Researchers have long understood the contaminating impact that feedback given to an eyewitness regarding their lineup identification has on a host of testimony-relevant retrospective judgments (Steblay et al., 2014; Wells & Bradfield, 1998). This phenomenon-the Post Identification Feedback Effect- has been influential in informing policy that seeks to reduce the number of false identifications and subsequent miscarriages of justice (Dysart et al., 2012). The present study aims to further our understanding and application of the post-identification feedback effect by investigating how a factor specific to the eyewitness, facial recognition ability, may moderate this effect. The present study failed to …

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 …

Stop Blaming My Users: Illumination Of The Technocentric Mythos Bias, Ervin H. Frenzel, Richard Lightcap

Journal of Cybersecurity Education, Research and Practice

 Abstract -This conceptual essay addresses the need for systemic and systematic transdisciplinary analytical techniques within cybersecurity and technical security. This conceptual essay is contingent upon recognition that cybersecurity is not simply technical in nature, it does not need an adversary, and more importantly it is based upon systems engineering and systems thinking.  The essay contributes a socio-technical attribution chain and field-specific ontology/taxonomy which distinguish user-triggered events from root causes, latent conditions, technical debt, validation failures, governance failures, and attribution bias before assigning responsibility to end users. It systematically defines an ontology inclusive of developer technical debt, organizational debt arising from …

The Role Of Rhyme In Children’S Word Learning, Tengwen Fan

LSU Doctoral Dissertations

Rhyme increases the phonological similarity of phrases individuals hear and enhances recall from working memory. The present study explores whether rhyme aids word learning in children and examines the underlying neural mechanisms through which rhyme facilitates word learning. Thirty-four children between 6 and 8 years old completed a word learning task where they were exposed to 15 nonwords (NWs), four times each, in the sentence-final position as their EEG was recorded. Participants were randomly assigned to either a Rhyme or No-Rhyme group, where the NWs rhymed or did not rhyme with a prime real word in the sentence, respectively, during …

Distributed Impressions: How Multiple Minds Come Together To Shape Person Perception, Lindsey J. Tepfer

Dartmouth College Ph.D Dissertations

Moments after perceiving another person, we immediately infer a wealth of information about them. Despite the complexities within our social environments, we distill an incredible magnitude of details available to us into compressed representations of other people’s minds and mannerisms. Yet research has focused largely on mapping isolated stimuli—divorced from its messy context—to the spontaneous impressions they provoke. As a result, there are many unanswered questions about how our judgments are influenced by the rich and noisy social world we inhabit. Here, I’ve leveraged two paradigms to investigate how impression formation and updating may operate when the constraints of the …

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 …

The Readiness Reset: Sleep, Stress, And Pain Management For Tactical Performance, Lauren Fried

Tactical & Occupational Performance Conference

Tactical professionals operate in high-demand environments where sleep disruption, chronic stress, and persistent pain are often normalized, but these factors significantly affect readiness, resilience, and long-term performance. This session explores how sleep, stress, and pain interact at the physiological and neurological levels to influence decision-making, recovery, injury risk, and operational effectiveness in first responders and military personnel.

Participants will gain a deeper understanding of how nervous system regulation, circadian rhythms, and pain perception affect both physical and cognitive performance under stress. Drawing on current research and applied human performance principles, this session highlights practical, field-applicable strategies that tactical professionals and …

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 …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

Evaluation Of Neuroplastic Changes In Psychological Intervention And Contemporary Treatments Of Depression, Taylor Severance

Dissertations

Major depressive disorder is one of the most prevalent mental health disorders worldwide. There is a vast range of treatment options for depression, with varying levels of effectiveness. Recent treatments for depression have expanded, increasing alternative treatments, and it is unknown which treatments have the largest impact on depression. This research was designed to examine the treatments of depression, with a focus on psychotherapy and contemporary treatments such as ketamine, psilocybin, and transcranial magnetic stimulation. A literature review was conducted to assess treatment outcomes and neuroplastic changes in these interventions, as well as combinations of the interventions. Data were evaluated …

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: …

Understanding Behavioral And Representational Divergences Of Humans And Machines, Thomas Lasman Botch

Dartmouth College Ph.D Dissertations

Human behavior and cognition are strikingly variable: people differ from one another in their preferences and abilities, and even from themselves across situations. Yet this diversity arises from common neural machinery shaped by the complex environments humans inhabit. A central objective of cognitive neuroscience is to understand how this varied experience emerges from interactions between brains, agents, and environments. In this dissertation, I argue that comparing behavior and neural computation across humans, artificial systems, and contexts is essential for understanding the flexibility of human cognition. Across three chapters, I use this comparative approach to examine how the rich, multimodal contexts …

The Effects Of Misinformation And Source Credibility On False Recall In College Students, Ashlee Smolenski

Honors Capstones

Eyewitness testimony if often treated as strong evidence in legal systems, yet psychological research consistently shows that memory is not a perfect recording of events. Instead, memory is reconstructive and vulnerable to distortion. The present study examined whether exposure to misleading post-event information and differences in perceived source credibility would influence false recall in college students. Using a 2 x 2 factorial design, participants watched a brief video of a car accident and later received either misleading or neutral questions presented by a high credibility (police officer) or low credibility (elderly man) source. It was predicted that misinformation would decrease …

What Learning Benefits Can Leadership Bring To Social Dilemma Situations?, Kyisha M. Walter

College of Arts & Sciences Senior Theses

Social dilemmas are ethical dilemmas that citizens, students and employees face every day. When faced with a social dilemma, an individual must work alone and along with others in a group. These situations create conflict between personal and group interests and can be easily mismanaged. Research has started to tackle the question of how we can teach people to best manage a social dilemma. The current exploratory study asks the same question with respect to leadership. Undergraduate students (N=20) played a social dilemma board game twice in groups of four, received a lesson on social dilemmas, and completed …

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 …

Leading The Choreography: Preserving Creative Agency In Ai-Supported Problem-Solving, Mikhaila Ackerbauer

Creativity and Change Leadership Graduate Student Master's Projects

As artificial intelligence tools become increasingly present in creative and problem-solving contexts, a critical question emerges: how can users engage with AI in ways that preserve rather than erode their own creative capacity? This project explores that question through research synthesis, practitioner conversations, coursework, international conference presentations, and the development of custom AI chatbots trained in the Creative Problem-Solving process. The central finding is a theoretical triangle comprising three interdependent capacities: autonomy, creative self-efficacy, and critical thinking. Grounded in Rhodes' (1961) Four P's framework, the triangle sits within the Person dimension. Convergent themes across the literature, practitioner conversations, and direct …
