Exploring The Role Of Pleasure In Cognitive Tasks, Nafisa Kazi Iqbal

Dissertations and Theses

The present study investigates whether the experience of a pleasant-valenced physical stimulus will positively influence performance on a cognitive task. The concept of hedonics is explored as hedonic responses, emotional reactions to stimuli involving feelings of pleasure and displeasure, play a crucial role in various psychological processes. There is a limited amount of literature regarding pleasant smell and its impact on the performance of cognitive tasks. The reported study addresses this limitation by comparing Stroop task performance of participants in two conditions, pleasant scent and neutral scent. These findings add to our understanding of the impact of pleasant smell on …

How Autistic Children Define Novel And Real Words, Henry James Tomiser

Graduate Research Theses & Dissertations

Word knowledge is highly valuable to Autistic individuals, and although much research has characterized Autistic children’s vocabulary breadth (i.e., the number of lexical entries), less attention has been paid to vocabulary depth (i.e., the richness with which one understands a given word). In this exploratory post-hoc study, 11 Autistic children (one assigned female at birth) participated in novel and real word learning paradigms in which child-friendly referents were paired with CVCV word forms. Participants were then asked to provide open-ended definitions of the words. Definitions were parsed into meaningful subunits, or semantic features. Semantic features were coded by type of …

Emotion Regulation: The Effectiveness Of Reappraisal And Potential Benefit Of Music, Ezra J. Greidinger

College of Graduate Studies: Theses & Dissertations

Literature has supported potential benefits to cognitive reappraisal as a method of emotion regulation, as well as intentional music usage as an enhancer of these effects. It has been suggested that instruction be provided to individuals to use these methods, especially in highly stressed populations (Sakka et al., 2018). However, there has not been an experimental study to follow up on these claims. When instruction is provided, is cognitive reappraisal more effective than naturally developed habits in regulating anxiety, and would music enhance these effects? College students (N = 170) were randomly assigned to three treatment conditions: control, cognitive reappraisal, …

Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb

Psychology Faculty Publications

Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …

Establishing Hierarchical Classification Responding: Directly Trained And Emergent Responses, George H. Noell, Kristin A. Gansle, Hannah M. Sliman, Danielle M. De Lucia

Psychology Faculty Publications

Hierarchical classification responding (HCR) describes a collection of responses that require discrimination of logical relationships between stimuli based on their position in a categorical hierarchy. This study established HCR for a new hierarchy in young children through discrete trial instruction. Participants selected pictures corresponding to different hierarchical levels of categorization. We tested for the emergence of naming that matched the level of hierarchy presented, transformation of function, and class inclusion responding for the trained and novel stimuli. Correct responding to the target hierarchy was established and resulted in the emergence of class naming and transformation of function without direct instruction. …

Next-Day Effects Of Binge Drinking On Inhibitory Control In Laboratory And Naturalistic Settings, Justin Verlinden

Theses and Dissertations--Psychology

Binge drinking occurs at an alarmingly high rate, despite its negative consequences on behavior, health, and cognition. One acute cognitive consequence of binge drinking is the impairment of inhibitory control, or the ability to stop oneself from engaging in maladaptive or inappropriate behaviors. Specifically, during a binge episode, individuals display impaired inhibitory control while completing Go/NoGo or Stop Signal Tasks (SST). This impairment has been shown to be maintained for up to five hours post-drinking, even as breath alcohol concentration (BrAC) approaches zero. Evidence also suggests that binge drinking results in next-day deficits in attention, memory, and psychomotor speed. However, …

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 …

Gaining Voice, Creating Opportunity: An Exploration Of Non-Native English-Speaking Students’ Sources Of Self-Efficacy In U.S. College Public Speaking Classrooms, Desiree M M Flores-Molina

Graduate Studies Theses and Dissertations 2026

This qualitative dissertation explores the sources of public speaking self-efficacy among non-native English-speaking international students enrolled in U.S. college public speaking courses. The study applies Bandura's social cognitive theory to examine how students describe the experiences that shape their confidence and perceived ability to succeed, with attention to mastery experiences, vicarious experiences, verbal persuasion, and physiological and affective states. It also considers how classroom practices and instructor support contribute to or constrain students' confidence.

Data were collected through semi-structured student interviews, guided reflection artifacts connected to major speech assignments, and key-informant interviews with public speaking instructors. Thematic analysis was used …

Visual Cues Of Human-Likeness, Not Salience, Impact Trust-Related Human-Computer Interaction, Jordan Schotz

Graduate Studies Theses and Dissertations 2026

As interactions with digital agents become increasingly integrated into daily life, understanding how visual representations influence social decision-making is critical. Previous research in human-computer interaction has frequently confounded the psychological effects of an agent's perceived human-likeness with the underlying visual salience of the stimuli. To address these persistent gaps, the present study systematically isolated the effects of human-likeness and visual cue trustworthiness on trust behavior while controlling for objective image properties. The present study expanded on and normed the Virtual Avatar Facial Stimuli Set (VAFSS), a comprehensive database comprising hundreds of identity-matched photographs and computer-generated avatars varying across a spectrum …

Moral Identity And Cognitive Mechanisms In Moral Decision-Making, Zachariah I. Hamzagic

Theses and Dissertations (Comprehensive)

Moral identity can be broadly conceptualized as the degree to which an individual places moral values as directly relevant to their personal identity. A recently introduced developmental framework of moral identity argues that moral identity can be conceptualized as a lifelong goal. According to this theoretical framework, the moral identity goal (i.e., to be a moral person and engage in moral action) becomes stronger over the course of development by becoming more abstract (i.e., general), internalized (to satisfy personal ideals) and promotion (i.e., action) oriented. Additionally, the strength of the moral identity goal predicts moral functioning. To date there has …

Effects Of Pressure-Based Virtual Reality Training On Mental Toughness In Athletes, Rylee J. Aspinwall

UNF Graduate Theses and Dissertations

Athletes often underperform in high-pressure situations due to challenges in emotional regulation rather than deficits in physical skill. Mental toughness, broadly defined as the ability to maintain performance under stress, is a key determinant of athletic success but remains difficult to train using traditional methods. Virtual reality (VR) offers a controlled and immersive environment for simulating competitive pressure; however, its application for training mental toughness remains limited. The present study examined the effects of pressure-based VR training on psychological and physiological responses in collegiate baseball and softball athletes. Participants completed up to eight VR training sessions under either high-pressure or …

Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch

Theses and Dissertations (Comprehensive)

BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …

Towards An Understanding Of Learning In Immersive Virtual Reality: Investigating Learning Affordances To Bridge Theory And Practice, Gregory Mcgowin

Graduate Studies Theses and Dissertations 2026

This dissertation examines how modality-specific scaffolding shapes performance, presence, and transfer in immersive virtual reality (I-VR). Framed through theories of extended cognition, real-time guidance is conceptualized as cognitive scaffolding that structures perception and action by embedding task-relevant information within the environment. Situated within the learning sciences and informed by 4E cognition (embodied, embedded, enactive, extended), this work develops a framework for understanding how I-VR affordances relate to learning and performance.

The empirical study investigates how scaffolding modality (audio vs. visual) influences presence and performance in a VR racing simulation. Using a 3 × 2 × 2 mixed factorial design, 111 …

Detecting Error In Ai-Generated Text: The Effects Of Authorship And Word Presentation Speed, Gabriela Flores Cruz

Graduate Studies Theses and Dissertations 2026

The increased us of artificial intelligent (AI) chatbots powered by Generative Pre-trained Transformers has raised concerns about users’ ability to detect errors of AI-generated text. This dissertation examined how readers identify inconsistencies in AI-generated expository passages using the inconsistency detection paradigm from comprehension monitoring research. Across two experiments, it investigated whether perceived authorship and word presentation speed influenced inconsistency detection. Experiment 1 used a 3 (author: human, AI, no author) × 2 (inconsistency type: internal, external) between-subjects design. Perceived authorship did not significantly affect hit rates, sensitivity, or response bias. Exploratory analyses indicated that reading comprehension and working memory predicted …

Cognate Awareness Training For Novice L2 Learners: Orthographic And Phonological Routes To Vocabulary Learning, Jennifer M. Martin

Electronic Theses & Dissertations (2024 - present)

Within the study of cross-linguistic influence, research on cognate facilitation has consistently shown that proficient bilinguals process cognates (e.g., English “sock” and German “Socke”) more efficiently than non-cognates. However, less is known about how novice adult learners may benefit from these similarities during the earliest stages of second language acquisition or how instructional interventions might facilitate this process. This dissertation addressed this gap through experiments with English-speaking adults learning German. A series of experiments examined the effects of cross-linguistic similarity and explicit cognate awareness training on vocabulary acquisition. Experiment 1A found robust similarity effects in written recall and …

Audiovisual Motion Onset Asynchrony As Expectation Violation: Effects On Memory And Liking In Media Contexts, Sijia Song

Electronic Theses & Dissertations (2024 - present)

This research presents the first systematic investigation of motion-onset asynchrony (MOA) as a form of audiovisual temporal incongruency grounded in contemporary spatial audio and extended reality (xR) systems. MOA—the delay between the onset of visual and auditory motion—was manipulated at three levels (0 s, 1.1 s, 3 s) to test its effects on cognitive (memory) and affective (liking) outcomes during short 2D animated video viewing. Guided by inverted-U models of expectation violation, it was hypothesized that moderate MOA would be associated with the highest memory performance and liking ratings and that liking would mediate MOA’s effects on memory. Across two …

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, …

Relational Knowledge Restructuring: Explored Though Experimental And Bayesian Computational Methods, Ashley Nicole Douglass

Dissertations - ALL

Are people rational Bayesian learners that produce a final posterior belief that is a compromise of their prior and the amount of new data? If they are then can one create a model that can predict their final belief given an estimate of their prior belief and the new data? This study aims to explore this. The participants were presented with two relational structures, the initial and the alternative which contradicted each other to a certain degree. In condition 1 the alternative structure was similar to the initial and in condition 2 the structure had the same number of contradictions …

Creating A Radical Social Change Campaign To Restore Rational Thinking: A Theoretical Framework, John S. Long

Student Theses and Dissertations

Rational thinking is a skill and mindset that is under siege in modern society, becoming increasingly endangered as we devolve into increasingly hyper-partisan communities rife with echo chambers and confirmation biases. The most basic processes of analyzing issues and facts to develop clearly thought-out and defendable positions have been abandoned in favor of a zealous devotion to toe the party line, no matter the evidence or implications. What we are witnessing firsthand is the fast-approaching culmination of the post-truth era.

One might assume that an issue with such far-reaching implications across our entire society would generate a significant amount of …

Consciousness Studies In Community: Allan Leslie Combs’S Enduring Vision, Debby Flickinger Phd, Rebecca A. Damien Phd

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 …

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 …

Fixation Duration As Effective Biomarker For Cognitive Function: A Developing Systematic Review, Nicholas Kurtz

Undergraduate Research Symposium

Eye-tracking technology has transformed psychological research by providing a non-invasive, real-time window into attention, perception, and cognitive processing (Ahlstrom & Friedman-Berg, 2006). Fixation duration—defined as the length of time the gaze remains stable between saccades—has been continually utilized as a key biomarker of cognitive function, providing measurable insights into variant populations and their stage of cognitive development (Negi & Mitra, 2020). This ongoing systematic review synthesizes research examining fixation duration in relation to constructs such as attentional control, working memory, processing efficiency, and effortful or inhibitory control. The current review aims to answer whether longer fixation durations equate to better …

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 …

Face Recognition Ability: The Role Of Facial Experience Across The Lifespan, Kirsty Kulhanek

UNLV Theses, Dissertations, Professional Papers, and Capstones

The other-race effect is a phenomenon in which individuals are better able to recognize individuals of their own race than individuals of another race. These effects begin to develop during the first year of life and may be attenuated by intergroup contact. Limited research in the language domain has suggested that multilingualism may result in easier learning of non-native speech contrasts, so it is of interest whether early experience with racially diverse faces may result in more easily learning to recognize unfamiliar race faces. We conducted two studies to examine the effects of early diverse experience with faces on recognition …

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 …

Revisiting The Link Between Metacognition And Social Cognition, Mia I. Gaffoglio, Jojo Widi, Aaron Schurger

Student Scholar Symposium Abstracts and Posters

Research has suggested that the ability to think about our own thinking (metacognition) and the ability to understand others’ mental states (mindreading) may rely on the same cognitive resources. A study by Nicholson and colleagues (2021) found that people’s metacognitive accuracy decreased when they performed a mind-reading task at the same time, implying that the two processes interfered with each other. However, that conclusion is dependent on the assumption that the mind-reading task and a control task were equally difficult. If the mind-reading task was more difficult, having a lower performance could reflect general task difficulty rather than shared cognitive …
