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 …

Using Eye Tracking To Explore How Auditory-Visual Chunking Modulates Visual Search Strategies In Expert Musicians In The Presence Of Auditory Interference, Nicole Arco

Electronic Theses & Dissertations (2024 - present)

Experts show performance advantages during visual search due to their extensive experience with domain-specific stimuli. Experts form memory representations for meaningful visual patterns, called chunks, that group together multiple domain-specific features into larger patterns. The ability of experts to form chunks could allow them to more precisely encode a search template, which could facilitate visual search performance. In the domain of music reading, expert musicians might form chunks that are multimodal (i.e., using visual and auditory modalities). The current studies addressed the possibility that chunks are multimodal by extending a previous cross-modal visual search task to manipulate the presence of …

Social Media Appearance Pressures And Body Dissatisfaction In Collegiate Athletes: Model Refinement, Group Differences, And Exploratory Insights, Hannah Hunter Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

In considering athletes’ body image, it is necessary to examine the psychosocial factors, and related psychological processes, that influence it. The body-related pressures athletes experience while navigating social media represent a relatively new and increasingly influential factor that warrants further investigation. The purpose of this study was threefold: (1) to replicate and refine Miller and colleagues’ (in press) model; (2) to examine differences in model variables and relationships across demographic and contextual groups; and (3) to explore aspects of social media perceived as contributing to appearance pressures, as well as strategies athletes may use to mitigate these pressures and their …

Modeling Joint Visual Attention In Naturalistic Dyadic Interactions, Kuushini Thennakoon, Yasasi Abeysinghe, Bhanuka Mahanama, Vikas Ashok, Sampath Jayarathna

Computer Science Faculty Publications

Joint visual attention (JVA) provides important insight into how individuals coordinate attention during social interaction. Egocentric eye tracking enables the study of JVA in natural, multi-user settings. This work presents a multi-stage framework to identify and analyze JVA using egocentric video and gaze data. The approach consists of three steps: spatiotemporal tube-based visual similarity, gaze-guided object detection, and attention pattern analysis using the ambient–focal coefficient K. Results show that object-focused collaborative activities exhibit high JVA, with object detection capturing higher joint attention than visual similarity, whereas conversation-based or independent activities show lower and more fragmented joint attention. Analysis of K …

Susceptibility To High-Fidelity Misinformation: An Eye-Tracking Analysis, Yasasi Abeysinghe, Gavindya Jayawardena, Enkelejda Kasneci, Sampath Jayarathna

Computer Science Faculty Publications

With the rise of online misinformation and AI-generated text, understanding human perception of news truthfulness is critical. In this study, we examine visual attention and cognitive processing using eye-tracking measures as individuals read fake and real news articles sharing nearly identical structure and imagery, differing only in subtle textual changes. Using the public FakeNewsPerception dataset, we analyze advanced gaze measures, including scanpaths, AOI transitions, and luminance-corrected pupil measures, beyond basic gaze features, in relation to news truthfulness and perceived believability. Results show that, given the high fidelity of the fake news, readers exhibited comparable visual scanning patterns, attention allocation across …

Eeg Correlates Of Tactile Synchrony, Devon K. R. Gallagher

Theses and Dissertations (Comprehensive)

New research on the tactile system has suggested that cortical representations of body parts are not fixed, as previously thought, and are instead dynamically maintained through constant sensorimotor information and feedback. Within the somatosensory cortex (S1), the capacity for both permanent and temporary changes have been the topic of ongoing research. The current study aimed to corroborate whether 24 hours of a finger adhesion manipulation is sufficient to elicit behavioural and electrophysiological correlates from cortical reorganization of digit representations in S1, using a behavioural paradigm outlined by Kolasinski et al. (2016). Through electroencephalography (EEG) recording during a tactile discrimination task, …

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 …

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 …

Experience Is Not Enough: Allan Combs And The Developmental Conditions Of Integration, Maria Giovanna Vianello

Journal of Conscious Evolution

Allan Leslie Combs occupies a distinctive position in consciousness studies through his sustained attention to the relationship between experience, interpretation, and development. This article examines Combs’s enduring contribution by focusing on his insistence that extraordinary or altered states of consciousness are neither self-interpreting nor inherently developmental. Drawing primarily on Consciousness Explained Better and related works, the paper argues that Combs’s central insight lies in viewing interpretation as a function of one’s developmental stage rather than treating it as a reflective process applied after experience. This perspective is articulated most explicitly through the Wilber–Combs lattice, which correlates states of consciousness with …

A Return To The Real: Elder Wisdom, Story, And The Great Mystery Of Consciousness, Patrice V. Mathon-Nerad Phd

Journal of Conscious Evolution

This essay honors the life and legacy of consciousness scholar Allan Leslie Combs by exploring elder wisdom as an epistemic, ethical, and spiritual stance grounded in openness to the great mystery of consciousness. Drawing on Combs’s writings, Charlene Spretnak’s articulation of the Real, and Malidoma Somé’s teachings on elderhood, the essay contrasts elder understanding with contemporary psychiatric approaches that impose epistemic certainty upon the vastness and lived complexity of human consciousness. Portions of this essay are adapted from the author’s 2023 doctoral dissertation, Separation from the Real: The Power of Story at the Heart of the Civil Commitment Process, …

Comparing Love And Vaping: An Event-Related Potentials Study, Sandra J.E. Langeslag, Caitlynn Harriman, Telora O.J. Thomas

Undergraduate Research Symposium

People seem addicted to their beloved. This study aims to compare love and addiction. The research examines how craving, attention, valence, and arousal differ between a beloved and a vape. 14 participants who were in love and vaped at least once a day have been recruited so far (5 women, 9 men, 22-49 years) and data collection is ongoing. Participants completed questionnaires, a computer task, and valence and arousal ratings. During the computer task, participants viewed pictures of their beloved, vaping strangers, and neutral strangers while their electroencephalogram (EEG) was recorded. Participants experienced more craving for their beloved than a …

Exploring The Impact Of Inpatient Mental Health Care On Adolescents, Alexandria M. Mckahan

2025 Fall Honors Capstones Projects - Archive

Adolescent psychiatric hospitalizations continue to rise, yet there is limited research on which daily practices inside inpatient units genuinely support engagement and recovery. This project examined how structure, staff tone, and therapeutic programming influence adolescents’ participation and emotional stability within a real inpatient setting. The study focused on three questions: how structured routines affect recovery, what challenges staff face when supporting adolescents with complex needs, and how adolescents’ engagement patterns reflect their perception of care. Using a mixed-methods case study at Mesa Springs Behavioral Health Hospital, I conducted approximately twenty field observations, semi-structured staff interviews, and descriptive engagement tracking across …

Holding Space For Complexity: Remembering Leslie Combs, Kimberly A. Morelli

Journal of Conscious Evolution

This tribute reflects on the teaching legacy of Allan Leslie Combs, focusing on his capacity to hold space for complexity during intimate online salons conducted with students and colleagues. Drawing from my experience as a participant in these gatherings, the essay highlights Leslie’s emphasis on relational, creative inquiry over rigid theory. Rather than positioning development as linear progress or achievement, these conversations were experienced as an ongoing, reflective inquiry into consciousness itself. Leslie’s mentorship fostered deep personal reflection and affirmed lived experience as a valid and generative source of knowing. His legacy endures not only through his scholarship, but also …

Consciousness And Magic: A Tribute To Allan Leslie Combs, Sharon G. Mijares Phd

Journal of Conscious Evolution

This article discusses the originating and continuing ideas associated with the Society for Consciousness Studies (SCS). More than a historical account, the evolution of the SCS mirrors the revelatory and unifying experiences of members as they pursue the understanding of non-local and non-ordinary consciousness through lenses such as synchronicity and the imaginal realm. This tribute encompasses parapsychological emphases interwoven with mythological, shamanic, spiritual, and literary art, drawing parallels between Parmenides’s journey to the underworld and the exploration of “magic” in science. Primarily, the essay focuses on the contributions of Allan Leslie Combs and his capacity for uniting various contributions and …

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 …

Schema, Stigma, And The “We-Them” Divide: Perspectives On Ageism From Everyday Life To Healthcare, Temple D. West

English Theses & Dissertations

Ageism remains a pervasive and often underexamined form of discrimination, affecting older adults across both everyday and clinical contexts. This paper explores how cognitive schemas—mental frameworks that shape perception and experience—and stigma interact to reinforce a “we–them” divide between and older patients and healthcare providers, as well as between older and younger individuals in broader society. Through focus groups and listening to the voices of older patients, this study examines how assumptions of age-based decline are embedded in society and inform schemas of ageism. It considers how those schemas shape the spoiled identity of older people as a stigmatized group, …

Embodied Overcrowding And Sensory Tensions: A Carceral Autoethnography Of Philippine Jails, Dwayne Antojado

Ateneo School of Government Publications

In this paper, I undertake a sensorially oriented autoethnography of two Philippine jails, illuminating the visceral textures of carceral life that conventional sociological or criminological discourses often overlook. Drawing inspiration from Jewkes and Young's (2021) examination of Kyoto Prison, I foreground the overlapping realms of sight, sound, smell, and touch, arguing that incarceration is inherently a profoundly embodied phenomenon. By weaving personal reflections, field observations, and broader scholarly insights, I reveal how overcrowded dormitories, suffocating heat, and lingering bodily odours converge to redefine detainees' spatial, temporal, and psychosocial realities in ways rarely captured by quantitative metrics. While mindful of Nelken's …

An Interest-Driven Approach: An Interview With Professor Allan Leslie Combs, Laurel Waterman Phd

Journal of Conscious Evolution

On March 17, 2024, I interviewed Professor Allan Leslie Combs about his teaching for my doctoral research project titled Teaching With Consciousness: A Narrative Inquiry Into Scholars’ Experiences Teaching About Consciousness Beyond the Brain. In January 2025, Leslie reviewed a draft of my interview write-up and emailed me, saying, “Beautiful work! And I have to say I am honored by the description you give of my own teaching philosophy.” This article draws on Leslie’s stories and applies their insights to the theory and practice of consciousness education—a field exploring perspectives on the source and nature of consciousness and their …
