Perceptions Of Psilocybin-Assisted Psychotherapy And Standard Interventions For Nicotine Cessation, Philip Kamilar-Britt

Electronic Theses & Dissertations (2024 - present)

Clinical trials suggest potential therapeutic utility of psilocybin-assisted psychotherapy (PAP) for nicotine cessation. In response to promising outcomes, research into PAP for nicotine dependence is growing. However, attitudes towards PAP among the general public, especially daily nicotine users, remains understudied. To address this knowledge gap, we recruited daily nicotine users (N=534) to complete an anonymous online survey with questions on demographics, nicotine use, prior history with psychedelics, and attitudes towards PAP and standard interventions for nicotine cessation. As hypothesized, daily nicotine users were more familiar with standard interventions and rated them more favorably than PAP. Despite differences in treatment attitudes, …

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 …

Research Collection School of Social Sciences

In recent years, the intersection of artificial intelligence (AI) and psychology has garnered unprecedented attention, particularly following the advent of generative AI tools in 2022. These tools, capable of producing human-like text, images, and even deepening our understanding of cognitive processes, have not only captured the public imagination but also sparked new concerns and debates within the psychological community. While AI has been a subject of research for decades, the emergence of its generative capabilities has truly thrust AI into the spotlight. This article explores how these advancements are reshaping our understanding of human cognition and behavior, as well as …

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 …

From Physical Correlation To Emotional Connection: The Role Of Passive Haptics On Empathy In Virtual Reality, Jemely Robles

Dartmouth College Master’s Theses

Virtual reality is increasingly explored as a tool for cultivating empathy, and haptic feedback as a tool for enhancing immersion. This paper investigates the effects of combining the two.  Fifty-two participants experienced a custom-built VR scene in which a character was shown packing up a room. Participants were assigned to either a haptic condition, receiving passive haptic feedback corresponding to the character's actions, or a non-haptic control condition that did not receive any haptic input. Trait empathy was measured beforehand, and state empathy and engagement were measured after the experience. Thematic analysis was conducted on post-study interviews, and headset recordings …

Careless Responding: Testing The Theory Of Vigilance, Rusty Wilson

Graduate Studies Theses and Dissertations 2026

Careless responding (CR) has been identified as a threat to the psychometric integrity of cognitive and non-cognitive tests, with much of the current research focusing on the identification and removal of carelessness from dataset. While this research has proved fruitful in improving data quality, there has been a recent push to move towards preventing carelessness as opposed to post-hoc removal, which harms statistical power. However, the most common prevention strategy to prevent carelessness (pre-survey warnings) has shown equivocal effects. Additionally, the literature lacks an agreed upon theory to explain why carelessness occurs. To address these gaps I introduce theory from …

Self-Movement Cue Ability As A Potential Moderator For The Relationship Between Binge Drinking And Posttraumatic Stress Disorder Symptoms, Dominoe Anna Jones

Graduate Research Theses & Dissertations

Alcohol use disorder (AUD) has been found to co-occur in a range of 30% to 50% of individuals diagnosed with posttraumatic stress disorder PTSD. The current study aimed to assess whether this high comorbidity could be partially explained through a shared association with poorer function and reduced volume in the hippocampus. Self-movement cue processing, a behavioral ability previously shown to be associated with hippocampal functioning, was measured through a dead reckoning task (DRT) to test this hypothesis. The current study failed to replicate previous findings between alcohol use and DRT and alcohol use and posttraumatic stress symptoms (PTSS). Performance on …

Parental Distress, Coercive Control With Food, And Child Self-Regulation, Kattie Nguyen

UNF Graduate Theses and Dissertations

Self-regulation is the management of one's emotions, thoughts, and behaviors to adapt to a situation (Smith-Donald et al., 2007). During infancy and toddlerhood, parents foster self-regulation through co-regulation (e.g., sensitivity, responsiveness), helping children manage their emotions, behaviors, and thoughts (Butler & Randall, 2013). Parents who experience distress (e.g., depression, stress, anxiety) are more likely to use less responsive and harsher, controlling practices like coercive control. Coercive control with food is a practice where parents use food as threats or bribes to control their child’s emotions and behaviors (Vaughn et al., 2016). The present study examined the associations between parental distress, …

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 …

Unmasking Impression Management: Large Language Models For Detecting Socially Desirable Responding In Open-Ended Situational Judgment Tests, Barret Vermilion

Graduate Studies Theses and Dissertations 2026

Socially desirable responding (SDR) — the tendency to present oneself in an overly favorable light — remains a persistent validity concern in industrial-organizational psychology. Contemporary theory frames SDR as multidimensional, distinguishing agentic impression management (AM; inflating competence, dominance, and achievement) from communal impression management (CM; inflating warmth, cooperation, and prosocial qualities). Existing measures of AM and CM rely on self-report, which captures these constructs only at the level of generalized trait-like tendencies rather than as they naturally unfold in applicants' own language. This dissertation proposes a text-based alternative: detecting AM and CM in open-ended situational judgment tests (SJTs) of Big …

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. …

Stressful Life Events And Ocd Treatment: A Thematic Analysis Of Patient Perspectives, Emily E. Fenlon

Theses and Dissertations--Psychology

Trauma exposure, including interpersonal violence (IPV), is associated with increased risk and severity of obsessive-compulsive disorder (OCD). Exposure and response prevention (ERP) is the treatment of choice for OCD, yet research suggests a history of trauma and comorbid PTSD may adversely impact treatment outcomes. No studies have yet evaluated patient perspectives on the relationship between trauma, IPV and related sequelae and OCD treatment. The present study applies reflexive thematic analysis to interviews from individuals with a history of IPV who received exposure-based therapy for OCD. Interviews explored the influence of posttraumatic distress, impairment, and psychopathology on the treatment of OCD, …

Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …

Relative Utility Governs Working Memory For Drug-Associated Stimuli In A Novel Translational Paradigm, Maxwell E. Boileau

Theses and Dissertations--Psychology

Substance use disorder (SUD) remains a prevalent health concern, partially characterized by continued drug use despite aversive consequences. Contrary to accounts emphasizing cognitive deficits, drug versus non-drug choice data reflect sensitivity to reinforcement dimensions, with preference shifting systematically as a function of magnitude and probability. The present study tested whether another cognitive system, working memory, is similarly affected by relative utility. Preclinical studies have demonstrated sensitivity of working memory to reinforcement dimensions, but these are often attributed to the differential outcomes effect. Generalized matching models were fit to allomorphic choice data, allowing estimation of exchange rate parameters. A concurrent solid- …

Working Memory In The Pigeon: An Alternative Paradigm, Daniel Peng

Theses and Dissertations--Psychology

One of the most widely used measures of working memory in non-human animals is the delayed matching to sample (DMTS) design. While this design can assess for duration of working memory, alternative accounts can be made to explain decrements in retention. In addition, DMTS does not assess capacity of working memory in terms of number of items able to be held. The works in this dissertation aims to design a paradigm to measure capacity of number of items held in memory for non-human animals by asking animals to make a specific response after presentation of a random spatial sequence. While …

The Charity Capacity Curse, Shirley (Lijun) Zhang, Thomas Allard, David Hardisty, Shane Wang

Research Collection Lee Kong Chian School Of Business

Can displays of charity capacity cues paradoxically harm charities' fundraising efforts? Six pre-registered studies provide evidence of a charity capacity curse whereby donors penalize charities for displaying capacity cues, such as human resources capacity, organizational capacity, and financial capacity cues. This curse occurs because donors perceive higher-capacity charities as needing less help. As donors typically donate based on need, they donate less to charities with superior capacity signals. This effect is attenuated when: (1) higher-capacity charities' needs are made salient, and (2) donors reflect on how their decision impacts end-beneficiaries. This research contributes to the literature on effective altruism and …

Brief Therapy Dog Interactions May Increase Self-Efficacy And Lower Perceived Stress And Cortisol In High School Students: A Preliminary Study, Dawn Melzer, Deirdre Yeater, Madison Derubis, Christiana Rose Kohlroser, Barbara J. Pierce

Psychology Faculty Publications

The present study examined changes in high schoolers’ perceived stress, general self-efficacy and cortisol levels after a brief interaction with a certified therapy dog. High school students completed self-report measures of perceived stress and general self-efficacy and provided salivary cortisol samples both before and after a 10-min interaction with a certified therapy dog. Following the interaction, students reported reductions in perceived stress scores, exhibited lower salivary cortisol concentrations and demonstrated increases in self-efficacy scores compared to before the interaction. Although higher self-efficacy scores were observed, general self-efficacy is generally regarded as a stable construct; therefore, these findings may reflect a …

Pretend Play Effects On Autistic Children's Theory Of Mind & Social Skills, Joelle Lok

Cal Poly Humboldt theses and projects

Autistic individuals often struggle with basic social skills due to deficits in Theory of Mind (ToM), perspective taking, reciprocity difficulties, etc. Early interventions that target these skills, specifically metarepresentation skills, could be essential to an individual’s social success and overall well-being. Further, pretend play shares an important relationship with ToM and social skills, due to their shared use of putting oneself in others’ shoes. Thus, a pretend play intervention could be beneficial in not only improving children’s overall play interactions, but also through a domino effect on their ToM and social skills. The directionality of the relationship between pretend play, …

How To Reduce Inpatient Violence: A Theory Synthesis From Four Models, Arthur Walker

Antioch University Dissertations & Theses

Working in an inpatient setting inherently involves an increased risk of violence. This violence can affect both staff and patients alike and can lead to psychological trauma, serious bodily injury, and even death. To mitigate this risk, many models for preventing inpatient violence have been proposed for hospitals to implement. However, the evidence for the efficacy of these methods is inconsistent, and the theoretical underpinnings are varied and slim. This dissertation seeks to improve these models by re-examining the theoretical structures for common themes of four models for inpatient violence reduction and proposing additional recommendations informed by this synthesis. First, …

Beyond The Rabbit Hole: Dmt, Death, And The Hereafter, Abby Molina

Antioch University Dissertations & Theses

This dissertation explores a proposed relationship between death and N,N-dimethyltryptamine (DMT) within the context of contemporary clinical psychology and the current psychedelic renaissance. Building on Rick Strassman’s hypothesis that DMT may be released at the moment of death and Imants Barušs’ conceptualization of death as an altered state of consciousness, this project examines the phenomenological similarities between DMT-induced experiences (psychedelic “trips”) and near-death experiences (NDEs). Through review of neurobiological research, psychedelic-assisted therapy literature, religious and cultural ceremonial practices, and documented DMT trip and NDE reports, this work evaluates the plausibility that endogenous DMT contributes to altered states of consciousness observed …

Adverse Childhood Experiences Of Individuals Charged Or Convicted Of Homicide In Their Youth, Marcus Krodel

Antioch University Dissertations & Theses

Adverse Childhood Experiences (ACEs) represent a collection of distressful events occurring during childhood and have been shown to have a negative impact on future functioning. ACEs were utilized in the current study to increase our understanding of a unique population among court-involved individuals: juveniles charged or convicted of homicide. Court decisions have established that juveniles convicted of homicide are both distinct from their adult counterparts and present with dissimilar risk and protective factors. The current study explored a sample of 66 individuals who were charged or convicted of homicide while in their youth. Each participant was retroactively assigned an ACEs …

The Lived Experience Of Tenders Of Community Grief Rituals, Margaret Y. Wilson

Antioch University Dissertations & Theses

The purpose of this research study is to gain an understanding of the lived experience of tenders of community grief rituals, and how tenders make meaning of their experiences. This study utilized photo elicitation and a reflexive thematic analysis. Participants (N = 11) provided one to three photographs that captured their experience of grief and/or tending grief rituals. The results identified 10 themes supported by subthemes: (a) Grief Tender Wisdom About the Nature of Grief, (b) Life’s Many Experiences are Sources of Grief, (c) The Multifaceted Impacts of Grief-Body, Anger, Compassion, Empathy, Resilience, Gratitude, Joy, and Love, (d) The Nuances …

The Use Of Mindfulness In Empirically Supported Treatments In Psychology, Timothy Stewart

Antioch University Dissertations & Theses

After gaining popularity in the United States of America (USA) in the 1960s and 1970s, Buddhist mindfulness was introduced to clinical psychology and investigated for its potential psychological healing effects. In the years since, mindfulness has been widely used in empirically supported treatments (ESTs) in clinical psychology in the USA to treat a wide variety of psychological conditions and disorders. This dissertation examines and compares conceptualizations and implicit understandings of mindfulness in early (Theravāda) Buddhism and in ESTs in clinical psychology in the USA. Through textual narrative analysis of two Buddhist sutta and 10 clinical psychology journal articles, this study …

The Effect Of Paternal Engagement On The Sexual Self-Concept Of Black Female Adolescents, Amelia Flynn

Antioch University Dissertations & Theses

Black women in the U.S. continue to experience disproportionately high rates of unintended pregnancies, with a 64% rate reported in 2011 (Finer & Zolna, 2016). Positive sexual self-concept (SSC) is linked to healthier sexual behaviors, yet research on SSC development has largely overlooked the role of fathers and systemic influences, particularly within Black families. Grounded in an ecological framework, this study examines the impact of father-daughter engagement on SSC among Black female adolescents, considering paternal residential status and socioeconomic class as key contextual factors. The study revealed that when middle class father-daughter engagement is high, daughters’ sexual self-esteem is lower. …
