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 …

Three-Dimensional Shape Cues Affect Human And Artificial Recognition Systems Differently, Mikayla Cutler, Luke D. Baumel, Joseph Tocco, William Friebel, George K. Thiruvathukal, Nicholas Baker Dr.

Computer Science: Faculty Publications and Other Works

Humans and neural networks use shape and texture information differently. While humans weigh shape heavily in their ultimate classification decision, neural networks are more biased towards texture cues. Many tests of shape vs. texture bias have focused on shape recognition from an object’s external contour. However, shape information is also conveyed through internal contours, shading, and attached shadows, especially when an object is viewed from noncanonical perspectives. Using models from ShapeNet, we created datasets of 120,000 texture-substituted images of objects from many viewpoints with and without shading and attached shadows. We tested humans’ and several neural networks’ ability to classify …

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: …

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 …

Generative Ai And Student Engagement, Motivation, And Learning: Exploring The Use Of Generative Ai In Higher Education Online Courses, Jeffrey L. Simmons

Dissertations

ABSTRACT

The rapid emergence of Generative AI (GenAI) large language models (LLMs) such as ChatGPT in higher education has left many institutions unprepared to assess their potential benefits and risks. This mixed-methods study examined how ChatGPT and Google’s NotebookLM were integrated into online course development and delivery at a small private nonprofit university in California, and assessed their perceived impact on student engagement, motivation, and learning.

Data were collected from post-course Likert-scale surveys completed by students across three online master’s-level courses and from pre-course prediction surveys by instructors in the two NotebookLM courses. Quantitative analyses included one-sample t-tests against a …

Brain-Based Mechanisms Of Behavioral Impairment In Fetal Alcohol Spectrum Disorder (Fasd): The Neuroimaging Biomarkers Of Inhibitory Control, Zinia Pervin

Biomedical Engineering ETDs

The developing brain is highly susceptible to alcohol-induced toxicity, often resulting in long-term deficits in executive function and behavioral regulation. Inhibitory control impairments are among the most prominent deficits observed in Fetal Alcohol Spectrum Disorder (FASD). This study investigated the neural mechanisms of inhibitory dysfunction using a multimodal MEG–DTI approach in 67 children aged 6–8 years (34 with FASD, 33 controls) who performed a Go/No-Go task. Source-level MEG analyses revealed reduced stimulus-locked cortical activation in the anterior cingulate cortex and significant group-by-hemisphere interactions in the superior parietal cortex and cuneus. Time–frequency analyses showed diminished response-locked beta power in the sensory-motor …

What Is The Skeleton Of Cognition? A Structural Account Of World Reconstruction Through Processing Axes, Griselda Poe

Publications and Research

This paper describes how the placement of a single processing axis reorganizes human cognition and generates a reconstructed world.

Most existing psychological and social theories begin from emotion, desire, morality, or social behavior. In doing so, they have discussed what forms on top of the cognitive skeleton without first fixing the skeleton itself. When the skeleton is not fixed, entirely different explanations of the same phenomenon can coexist, and it becomes difficult to identify which constitutes a foundational account.

This paper fixes the skeleton first. That skeleton is the processing axis.

The question is: when a single processing axis organizes …

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 Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber

Student Theses 2015-Present

This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …

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 History Shows: A Structural Account Of Fixed-Point Theory Formation, Griselda Poe

Publications and Research

Theory generation has long been subsumed under categories such as creativity, genius, and innovation. These categories do not distinguish assembly-based conceptual synthesis from fixed-point theory generation.

This paper makes that distinction explicit. The termination condition of assembly is external: data, citation, endorsement, usability. The termination condition of fixed-point theory generation is internal: consistency with internally held constraints, resolution of structural contradiction. The two operate under different processing conditions.

The historical record confirms this distinction. What Darwin, Einstein, Spinoza, and Kant produced was not assembly. Their processes involved unresolved branch retention and decomposition necessity, arriving at internally constrained fixed-point termination. Freud …

In The Era Of The Smartphone: The Case For The Continued Role Of Mnemonics As Cognitive Scaffolds That Support Encoding, Working Memory Efficiency, And Rapid Cue-Dependent Retrieval, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: The ubiquity of smartphones and point-of-care digital references has prompted questions regarding the continued relevance of mnemonic devices in medical education. If information can be instantly retrieved, is memorization—and by extension mnemonic structure—still necessary? Objective: To reframe mnemonics not as relics of pre-digital pedagogy, but as cognitive scaffolds that support encoding, working memory efficiency, and rapid cue-dependent retrieval in time-pressured clinical environments. Discussion: Cognitive science demonstrates that working memory remains inherently limited regardless of technological access. Mnemonics function as structured chunks that reduce cognitive load, support pattern recognition, and facilitate transition from novice encoding to expert automaticity. In emergency …

The Brain And Becoming: Integrating Play And Performance-Based Learning In The Community College Classroom, Hannah M. Green

English

Instruction in the community college classroom is in need of a shift, according to neuroscientific, pedagogical, and demographic data. Primarily, students in today’s community college classrooms are instructed in the form of lectures (Nilson 106), but research has shown that game-based learning would be the way to enhance learning experiences for these adult learners. Game-based learning specifically takes form in student learning through games, interactive reading activities such as performance pedagogy, discussions, and small group work. While research shows that play-based learning at the community college level is neurologically beneficial for students, there is a gap in implementing play-based learning …

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 …

Processing Conditions In Narrative Interpretation: A Structural Account Of Cf/Ef Divergence In "The Clerk's Tale”, Griselda Poe

Publications and Research

This paper applies the framework established in Paper 19, "Cognition Is Not Content: A Structural Account of Processing Conditions," to re-describe Chaucer's "The Clerk's Tale" from The Canterbury Tales.

The same narrative produces two incompatible interpretations: a record of domestic violence, and a story of genuine love. This divergence does not arise from differences in ethical judgment or emotional response. It arises from structural differences in the conditions under which information is reconstructed.

This paper does three things. First, it analyzes the characters Walter and Griselda in terms of CF (Core-foregrounded) and EF (Modulation-foregrounded) processing conditions. Second, it describes …

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 …

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.

Prism: Priming Relationships In Syntax And Mathematics, Michelle J. Zhu

Honors Scholar Theses

The implementation of sheltered education programs has become increasingly prevalent in schools as new research in second language acquisition emerges. Yet despite this growing attention to ESL instructional practice, far less is known about the cognitive processes that underlie how bilingual students engage with academic content. This study investigates cross-domain structural priming between mathematical and linguistic processing in monolingual and bilingual individuals, focusing on how bilingual experience influences syntactic attachment preferences. Prior research suggests that mathematical and linguistic structures share underlying cognitive representations, and that exposure to structures in one domain can influence processing in another. Additionally, bilingualism has been …

Prefrontal Engagement In Cognitive Flexibility Across Paradigms, Katarina Kalajzic

Honors Scholar Theses

Cognitive flexibility is an executive function that involves dynamically adapting behavior in the face of changing environmental circumstances to achieve a particular goal. Disrupted in numerous psychiatric disorders such as Alzheimer’s disease, schizophrenia, OCD, and depression, the neural correlates of cognitive flexibility are not well understood. However, the prefrontal cortex (PFC) is strongly implicated in executive function and attentional control processes. Thus, we sought to examine the neural circuitry involved in distinct cognitive flexibility tasks – the attentional set-shifting task and the probabilistic 2-armed bandit task. Through optogenetic suppression, we targeted pyramidal neurons of the rodent medial prefrontal cortex, an …

Ai In Wonderland, Bodj Oliver Alngohuro

Honors Scholar Theses

Studies in sound symbolism have revealed a baseline preference for people to associate certain sounds with certain concepts. The Bouba/Kiki effect, for instance, reveals a preference for individuals to associate “Bouba” with a round shape and “Kiki” with a sharp shape (Köhler 1929). Other studies have revealed other associations with certain sounds and names with concepts, such as “Mil” referring to something small and “Mal” referring to something big (Sidhu and Pexman, 2017). This study looks at LLMs and how they compare to humans concerning intuitions for certain names based on sound symbolism.
