The Association Between The Number Of Languages Spoken, Working Memory, And Emotional Regulation In Monolingual English Speakers And Fluent Multilingual English And Non-English Speakers, Eun-Sung Chang

Doctoral Dissertations

Despite the growing linguistic diversity of the population in the United States, multilingual individuals remain underrepresented in psychological research and often experience disparities in access to culturally and linguistically appropriate mental health care. Using a cross-sectional design and quantitative methods, the present study examined the relationships among the number of languages spoken, working memory, and emotional regulation. A total of 94 participants (30 monolingual English speakers and 64 multilingual speakers who spoke English and at least one other language fluently) completed the Working Memory Index (WMI) of the WAIS-IV and the Difficulties in Emotion Regulation Scale (DERS). Results revealed no …

Factors Contributing To Executive Function In Young Adults, Lindy Janae Stevenson

McNair Scholars Research

Executive functions (EF) are skills used to complete desired behaviors and inhibit undesired ones. These skills are necessary for everyday life, and even more so in higher education and the workplace. This study examined the combined impact of sleep and exercise on five facets of EF in young adults enrolled in undergraduate or graduate courses. It also examined how perceived effort and performance in college classes interact with EF. The first five hypotheses studying sleep and exercise were analyzed using a 2x2 between-groups ANOVA. The data divided participants into those averaging fewer than 7 hours of sleep a night and …

The End Of Unmeasured Exploitation: How A.S.M., C.A.S., And S.I.A. Challenge Digital Attention Capitalism, Delante Clark

Graduate Scholarship and Creative Works

Digital attention capitalism generates value through the capture and monetization of human attention, yet it has historically lacked standardized mechanisms for measuring attention-related harm. This paper argues that the Attention Safeguard Models (A.S.M.), Cognitive Attentional Standards (C.A.S.), and Sociological Impact Assessment (S.I.A.) collectively challenge this system by introducing an integrated framework for classifying, measuring, and evaluating digital attention harm and its societal consequences. C.A.S. provides standardized measurement of digital attention harm, A.S.M. identifies and classifies patterns of attentional disruption and manipulation, and S.I.A. evaluates broader impacts on institutions, communities, civic engagement, education, social cohesion, and inequality. Together, these systems transform …

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, …

A Geometric Framework For Modeling Real-World Experience, Knowledge, Learning, And Memory, Paxton C. Fitzpatrick

Dartmouth College Ph.D Dissertations

A growing body of recent work highlights the importance of studying learning and memory in “naturalistic” contexts that reflect how these processes function in our day-to-day lives. Yet the incredible complexity of the world around us, and of the idiosyncratic ways we learn from and remember it, make characterizing the dynamics of learning and memory for real-world experiences challenging. I present a computational framework that leverages the embedding representations of language models to cast experiences and memories as high-dimensional trajectories unfolding through a common representation space, enabling them to be directly related and compared via their latent semantic geometries. I …

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.

It illustrates the model through a General Education course, Leadership for Global Challenges: Exploring the Digital …

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 …

Investigating The Role Of Striatal Cholinergic Interneuron D2 Receptors In Behavioral Flexibility, Janyn J. Alfred

Dissertations, Theses, and Capstone Projects

Dopamine (DA) and acetylcholine (ACh) interact within the striatum to shape reward-based learning and choice behavior. DA D2 receptors on cholinergic interneurons (CIN D2Rs) were genetically knocked out to investigate their role in choice allocation using a two-lever matching paradigm. Behaviorally, both knockout (KO) and wild-type (WT) mice learned the initial task equally well. When shifted to asymmetric matching schedules (VI-90 vs. VI-180), ideal matching predicts that mice should allocate exactly 67% of their total responses to the rich lever. Neither group matched as predicted by the matching law. Instead, the KO mice showed a pattern where the higher rate …

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 …

Writing Together, Writing Differently: Collective Authorship As Reflective Practice, Thanh Thao Le, Trut Thuy Pham

The Qualitative Report

This article examines collective authorship as a reflective and ethical research practice within a sustained program of co-authored qualitative, post-qualitative, linguistic, and reflective inquiries into teacher reflection, professional learning, language, silence, and recognition. It offers an oral-history-informed reflective methodological account of a writing collective and asks how collective authorship became a methodological practice through our collaborative writing process. The primary materials were shared drafts, margin comments, revisions, silences, version histories, short reflective notes, and remembered writing encounters. Teacher-reflection texts and related professional writing materials from our broader research program formed the secondary materials around which the writing process unfolded. Analytically, …

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 …

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" …

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 …

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 …

Governing Algorithmic Attention: Attention Safeguard Models And The Cognitive Attentional Standard As System Level Interventions In Human Computer Interaction, Behavioral Economics, And Artificial Intelligence, Delante Clark

Graduate Scholarship and Creative Works

Algorithmic recommendation systems and interface designs shape attention by combining visually salient cues with uncertain reward timing and low friction interaction. These conditions can sustain anticipatory checking, extend time on task, and reduce natural disengagement points through patterns such as infinite scrolling and autoplay. This paper synthesizes research across neuroscience, human computer interaction, behavioral economics, and artificial intelligence to argue that attention capture is a predictable outcome of incentive driven design rather than an individual failure of self regulation. It advances the Attention Safeguard Models and the Cognitive Attentional Standard as system level interventions that regulate exposure conditions, pacing, and …

The Impact Of Flight Instructor Feedback On Subsequent Instructor Evaluations Of Student Performance, Ayhan Rozyyev, Jennifer E. Thropp

Journal of Aviation/Aerospace Education & Research

This study examines the impact of feedback tone and feedback order on flight instructors’ evaluations of student performance in an aviation training context. Using a 2×2 mixed factorial design, 40 certified flight instructors reviewed fictitious training records and rated students based on feedback that varied in tone (positive vs. negative) and order (positive-first vs. negative-first). Results showed that positive feedback significantly influenced evaluations across all measured dimensions, while feedback order had no significant effect, challenging assumptions about primacy and recency effects. These findings highlight the role of positive reinforcement in shaping instructor evaluations and suggest that structured training environments can …
