Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski

Theses and Dissertations (Comprehensive)

This thesis addresses how animals cope with unpredictability by testing how environmental stability changes the behaviour of zebrafish (Danio rerio) in two complementary experiments. In Experiment 1, fish lived for three months in either a Dynamic environment (water temperature, feeding times, habitat complexity, group size, and membership fluctuated) or a Stable environment (all factors constant). Across seven behavioural assays, measuring individual behavioural differences, collective movement, social memory, and information use, Dynamic condition fish were found to be more sensitive to social cues and more likely to conform to recent social information, independent of the quality of the information …

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 …

Politics As Usual: Racial Pay Inequity And The Illusion Of Inclusion In The Rise And Fall Of Diversity, Equity, Inclusion, And Accessibility Executive Orders, Francois C. Melville

West Chester University Graduate Theses, Dissertations, and Final Projects

This research examines pressing moral policy questions of our time: who determines when the United States of America has fulfilled its broken promise of equality for all, and what constitutes an appropriate measure of reparative justice. It interrogates why the Diversity, Equity, and Inclusion (DEI) Executive Orders (EOs) implemented across presidential administrations, intended to advance social equity, were grounded in conflict and symbolic gestures rather than scientifically evidenced issues such as wage inequality directly linked to upward career mobility. Race conscious policy generates cultural clashes centered on the perception that gains made by Black and Brown Americans come at the …

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 …

Patterns Of Ovarian And Gonadotropin Hormones In Emerging Adult Oral Contraceptive Users, Summer Mcormond

Undergraduate Research Posters

Oral contraceptives (OCs) are often initiated during adolescence and emerging adulthood, a period of continued maturation of the hypothalamic–pituitary–gonadal (HPG) axis. Because hormonal exposure during this window may shape emotional, biological, and reproductive outcomes, it is important to understand the specific formulations young women take and the hormonal profiles these formulations produce. This study characterizes OC formulation features and measured hormone levels in young adult OC users (n = 30).

Ethinyl estradiol (EE) doses ranged from 0.01–0.035 mg (mean = 0.022 mg), with 70% using ≤0.02 mg. Pill regimens included 21/7 packs (83%), 24/4 packs (10%), and 84/7 regimens (3%). …

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 …

Face Value: A Computational Approach To Subjective Impressions Of Faces, Kevin Kpankou

Undergraduate Research Symposium

Various computational models of first impressions have been developed to uncover the mechanisms driving these judgments. However, the implicit notion of a singular ``human'' often overlooks meaningful individual differences in beliefs, attitudes, and associations, as well as culturally grounded group-level constructs. In this paper, we extend Cultural Consensus Theory (CCT) to estimate culturally shared beliefs about faces by incorporating latent constructs structured around interpretable facial features extracted via computer vision algorithms. We apply our model to a large-scale dataset of people’s first impressions of faces. Our approach reveals a robust mapping between facial features and culturally constructed impressions, allowing us …

Moving Toward Healthy Ageing: The Role Of Physical Activity In Cognitive Function And Self-Esteem Among Older Adults In Türkiye, Canan Birimoglu Okuyan, Müjde Kerkez

Makara Journal of Health Research

Background: This study aimed to evaluate the relationship between religious attitudes and breastfeeding attitudes and the effect of this relationship on breastfeeding practices.

Methods: A cross-sectional study was conducted with 251 older adults. Data were collected using the International Physical Activity Questionnaire, the Standardized Mini-Mental State Examination, and the Rosenberg Self-Esteem Scale. Spearman’s correlation and chi-square tests were employed for statistical analysis.

Results: Physical activity levels were positively correlated with both cognitive function (r = 0.546, p < 0.001) and self-esteem (r = 0.168, p < 0.05). No significant association was observed between cognitive function and self-esteem. Physical inactivity, cognitive decline, and low self-esteem were more prevalent among women, participants with lower educational attainment, those with chronic diseases, and individuals engaged in polypharmacy.

Conclusions: The findings emphasize the importance of integrating physical activity promotion into national healthy ageing policies, particularly in Mediterranean contexts such …

Reading Between The Lines: The Influence Of Financial News On Investor Decision-Making, Kalia Noble

Honors College Theses

This thesis investigates how financial media narratives shape investor sentiment and short-term market behavior. Drawing on behavioral finance and narrative economics, it examines whether the framing and tone of market news correlate with intraday volatility in the S&P 500 and Dow Jones Industrial Average. By pairing quantitative price data with contemporaneous headlines from major outlets such as Bloomberg, Yahoo! Finance, and CNBC, the study shows that emotionally charged or speculative narratives are closely associated with sharp market swings, even when fundamentals remain unchanged. These findings highlight the influence of media framing on investor decision-making and underscore the importance of financial …

Part I: Building Stronger Camp Communities Through Motivation As A Connected Process, Kelley Freridge

CompassPoint

Every summer, millions of children, youth, and young adult staff members gather in camp communities seeking adventures, community, and growth. They arrive carrying stories of who they are and who they might become. While some camp professionals have explored the existing research on motivation, many still struggle with this question: how do we move beyond temporary, programmatic reward-driven compliance or temporary entertainment-centered enthusiasm to spark genuine, sustained engagement that transforms both individuals and the community?

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 …

Large Language Models As Machines Of Beauty: Cognitive Averaging, Latent Space Geometry, And The Entropic Foundations Of Aesthetic Preference, Daniel Plate, James Hutson

Faculty Scholarship

This study advances the position that large language models (LLMs) and human perceptual systems are governed by a shared computational drive toward prototypicality, entropy reduction, and aesthetic coherence. Drawing on developmental evidence that infants exhibit early preferences for facial symmetry and averageness, the analysis situates aesthetic preference within broader research on processing fluency and predictive coding, emphasizing that biological perception rewards stimuli that reduce uncertainty and support efficient information compression. This foundation is used to examine how LLMs, through cross-entropy optimization, perplexity minimization, and latent space clustering, converge on high-density representational regions that operate as statistical prototypes of linguistic and …

Exiting Commercial Sexual Exploitation, Jeanne L. Allert, Sherri L. Wyatt

Dignity: A Journal of Analysis of Exploitation and Violence

This study presents one of the largest qualitative samples of exited female survivors of commercial sexual exploitation in the United States to date. One hundred and eighty-nine female survivors participated in a national survey. The participants described their motivations for exiting commercial sexual exploitation, the pathways they followed, the forces that hindered their exit and increased their recidivism, and the assistance they received that ensured a permanent exit. Some of the findings challenge popular narratives on recidivism rates and what keeps women in exploitation, revealing complex relational, behavioral, economic, and systemic influences. Participants spoke about the unanticipated value of incarceration, …

Utilizing a qualitative case study approach, this dissertation draws on fourteen student interviews, seven that passed Step 1 on their first attempt, and seven that failed. Findings reveal …

Educational Ai Agents In Vr, Jake Eichenseer

Graphic Communication

AI powered educational agents are programs that are capable of interpreting their environment and then making decisions based on that (Cordova-Esparza, 2025). Agentic programs like these can be helpful in an educational setting because they can be used to provide personalized feedback to students, assist instructors with grading, and adapt learning materials in real time to match each student’s progress. However, there are a multitude of concerns raised by agentic programs as well, causing experts to consider the ethical implications of integrating them into school curricula. The Cal Poly Graphic Communication Department wanted to study how participants would respond when …

Improved Model For Neurodegeneration In C. Elegans, Jean-Pierre Arditi

Graduate Theses and Dissertations (2019 - present)

During Alzheimer's disease (AD), insoluble amyloid beta (AP) peptides accumulate to form extracellular aggregates (plaques). The direct cause of neuronal dysfunction observed in AD has been broadly investigated. The amyloid hypothesis states that AP plaques are neurotoxic, but recent studies support the AP oligomer hypothesis, which states that intracellular AP (iAP) is neurotoxic. To test this hypothesis, I used CRISPR-Cas9 gene editing to generate two transgenic Caenorhabditis elegans (C. elegans) strains. I generated a strain (RSLl 11) using the rab-3 promoter to co-express GFP in neurons, which showed no gross behavioral changes but had a 50% reduced egglaying rate. RSLl …

Analyzing Patterns In Hofstede’S Cultural Dimensions Towards Individual Ai Receptiveness For Affective Experiences, Maggie Yang

Master's Theses

The use of artificial intelligence (AI) has significantly advanced efficient decision-making, with trust in algorithmic decisions shown to vary by cultural upbringing [1]. As AI becomes increasingly embedded in everyday life, it is essential to examine how cultural values affect trust in AI in subjective contexts that extend beyond purely quantitative analysis, like the personal interpretation of art. This work utilizes Hofstede’s cultural dimensions to investigate potential patterns in receptiveness towards AI predictions during art interpretation, providing insight into individual susceptibility to bias in AI-assisted affective analysis.

The study leveraged a cultural dimension survey and a custom Java program connected …

Empathy On Trial: The Role Of Neuroscience And Communication In Sexual Violence Jurisprudence, Samantha M. Gonzales

Honors Program Theses and Research Projects

Sexual violence remains a contentious public safety and legal challenge, which has become further complicated by the tension between supporting victim-survivors and safeguarding the falsely accused. False accusations, though still well below the numbers of rightly accused, are experiencing a rise in popularity given recent (past ten years) political climates. This thesis examines how communication theory, neuroscience, and law intersect in molding perceptions of truth, culpability, and justice in sexual violence cases; while also examining the intersectionality of those fields in addressing the candor of allegations, the rate of recidivism, and quality of public health and safety. The most prominent …

Selective Attention With Lyrical Music Vs. No Music, Scovs Majors, Rachel Falleur, Kim Niang, Olivia Pokrifcsak

Science University Research Symposium (SURS)

Selective attention refers to the brain’s ability to focus on relevant information while filtering out distractions. Research suggests that language cues and semantic context can shape how attention is directed, indicating that cognitive control is context-dependent (Reisman, 1964). Environmental factors such as background noise can also disrupt attention, leading to reduced accuracy on cognitive tasks (Pearson & Lane, 1984). In the present study, we examined music as both a linguistic and environmental variable influencing selective attention. Previous findings indicate that lyrical music can serve as a significant distractor, impairing attentional performance in both music and non-music majors (Darrow et al., …

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 …

A Lost Culture Of Touch And Sound: The Contribution Of Visually Impaired Musicians To The Evolution Of The Spanish Guitar, Marco Ramelli

Soundboard Scholar

In the story of music-making, blind musicians have played an intrinsic role, helping to drive the development not only of musical styles but also of instruments, instruction, and aesthetics. Many musical practices were cultivated first within blind communities and adopted only later by sighted musicians, often with a gradual erasure of their original context. The history of the Spanish guitar offers a compelling case study of this progression, demonstrating how the contribution of blind musicians could be both wide-reaching and yet, over time, forgotten. The history of this contribution is challenging to recover, for in Spain as elsewhere, blind musicians …

Unraveling The Lullabies Of Learning: Exploring The Role Of Individual Components Of Infant-Directed Speech In Language Learning, Stephanie L. Lopez

LSU Doctoral Dissertations

Children learn language more effectively from infant-directed speech (IDS) than adult-directed speech (ADS). Three experiments were run (a pilot and two full experiments) testing the effects of pitch and pitch variability on segmenting a target word out of the speech stream and then associating it to an object. Visual prosody via eyebrow movements and lip contours were added as additional cues after the Pilot Study. Additional factors included after the Pilot Study were shortened sentences from 10 syllables each to seven syllables each, shortened target words from three syllables to two syllables, consistent syllable onset of target words, and two …

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.
