The Psychological Process Of Decolonizing The Colonized Self: A Grounded Theory Based On Hong Kongers’ Decisions After The 2019 Protests, Lai Kwan Shirley Lo Jan 2026

The Psychological Process Of Decolonizing The Colonized Self: A Grounded Theory Based On Hong Kongers’ Decisions After The 2019 Protests, Lai Kwan Shirley Lo

Antioch University Dissertations & Theses

Hong Kong, a British colony for over a century, was returned to China in 1997. In 2019, the proposal of an extradition bill sparked widespread outrage, leading to a year of unprecedented social unrest. The protests eventually dissipated with the advent of the COVID-19 pandemic and the Chinese central government’s tightening controls. Although the state characterized its interventions as decolonization, a significant wave of Hong Kongers responded by leaving their homeland to cultivate new lives in the “Western world,” including Britain. How does a colonized population willingly return to their colonizer after decolonization? This study sets out to search for …

Effect Of Delay On Reinforcer Preference And Efficacy, Ciara Jasmine Rodriguez Jan 2026

Effect Of Delay On Reinforcer Preference And Efficacy, Ciara Jasmine Rodriguez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Behavior intervention plans are used to increase desired behavior and decrease problem behavior, and these plans require the use of effective reinforcers. High-quality reinforcers that are delivered immediately tend to be the most effective, but optimal reinforcement parameters are not always feasible or appropriate in applied settings. Some reinforcers may be disruptive, teachers’ competing responsibilities may introduce delays to reinforcer delivery, and reinforcers may not be immediately accessible. Stimuli may lose their reinforcing value with delay to their receipt, and this is referred to as delay discounting. Thus, there is likely a point where a less preferred but immediately delivered …

Early Life Adversity And Reward Reactivity In Humans, Maria C. Potts Jan 2026

Early Life Adversity And Reward Reactivity In Humans, Maria C. Potts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Both animal and human research has identified early life adversity (ELA) as a prominent risk factor for substance use disorder (SUD). However, the underlying mechanisms linking ELA to SUD development remain unclear. Animal studies point to differences in reward responsiveness as the primary explanation; specifically, that ELA could lead to individual differences in the attribution of incentive salience to reward-predictive cues, or the “sign-tracking” behavioral phenotype. Sign-tracking has been linked to addiction-related behaviors in both animal and human studies, but no human studies have examined whether sign-tracking could partially explain the link between ELA and SUD. In fact, human studies …

Accessing Campus Mental Health Services In A Nigerian Southwestern University: Barriers To Academic Success, Caroline Dada Jan 2026

Accessing Campus Mental Health Services In A Nigerian Southwestern University: Barriers To Academic Success, Caroline Dada

Electronic Theses and Dissertations

Mental health disorders are a significant health concern among higher education institutions in sub-Saharan Africa, including Nigeria. A substantial treatment gap exists in the Nigerian healthcare system, and this gap is further worsened by cultural and religious barriers, which reinforce stigma that discourages students from seeking professional help. This qualitative narrative inquiry explored the barriers students encountered when accessing mental health services at a university in Southwestern Nigeria, to increase service access. Qualitative semistructured interviews were conducted with seven professional mental health providers at a university counseling center between March and April 2025. Inductive thematic analysis was used to identify …

Heat Misers, Snow Misers, And Cognitive Misers: The 'Nukewarm' Perceptions Of Nuclear Power, Tyler Williams Jan 2026

Heat Misers, Snow Misers, And Cognitive Misers: The 'Nukewarm' Perceptions Of Nuclear Power, Tyler Williams

Dissertations and Theses

Rising energy demand in the United States necessitates alternatives to fossil fuels, yet renewable energy sources alone are insufficient to meet this demand. Nuclear power presents a promising option but faces persistent public hesitancy. This study examines how heuristic-based biases relate to American's risk-benefit perceptions towards nuclear power. Guided by the heuristic-systematic model. Results indicate that competence and affect are related to risk-benefit perceptions, and naturalness shows no relationship with risk perceptions but does correlate with benefit perceptions. Implications highlight the importance of affect-driven communication strategies for nuclear communicators, while also underscoring the need for participatory approaches that foster trust …

Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms. Jan 2026

Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.

Theses and Dissertations (Comprehensive)

Cognition is widely believed to be adaptive, yet few studies directly show that variation in cognitive performance is related to fitness. Brown-headed cowbirds (Molothrus ater) provide a powerful system for addressing this gap because brood parasitism creates strikingly different reproductive problems for females and males. Females face the spatial demands of nest-prospecting, whereas males face social and competitive demands associated with access to mates. Across five experiments, cowbirds were tested on an outdoor foraging task designed as an analogue of nest prospecting, with manipulations of retention interval, cue conflict, and breeding condition, followed by observations of reproductive behaviour. …

“Do We Play By The Same Rules?”: Exploring The Involvement Of The Magic Circle In Navigating Relationships In Popular Multiplayer Video Games, Nathan Toshihiro A. Villanueva, Julianne Margaret M. Lao, Thea Juliana Alvarez Jocom, Liezl R. Astudillo Dec 2025

“Do We Play By The Same Rules?”: Exploring The Involvement Of The Magic Circle In Navigating Relationships In Popular Multiplayer Video Games, Nathan Toshihiro A. Villanueva, Julianne Margaret M. Lao, Thea Juliana Alvarez Jocom, Liezl R. Astudillo

Sinaya: A Philippine Journal for Senior High School Teachers and Students

Just like leveling up in a game, dating has transcended the physical world into the realm of multiplayer games where individuals are able to communicate and interact with one another within the virtual third space, the magic circle–the boundary that separates life from play. Within these immersive environments, players create shared experiences that often extend beyond the screen, blurring the line between in-game interactions and real-life emotions. This blurring can lead to emotional spillovers and identity challenges as players navigate the complexities of digital intimacy in world and relationship formation. To define the fluidity of the magic circle, the study …

From Companionship To Grief: Lived Experiences Of Adolescent Dog Owners At De La Salle University, Dave Edrich Lao, Oel Bes, Zachariah Moscardon, Renzy Sabandal, Noel Bedia

Sinaya: A Philippine Journal for Senior High School Teachers and Students

Pets have long been part of people’s lives, but today, they are often viewed as family, especially by adolescents who rely on them for comfort, support, and companionship. For many, the bond with a pet runs deep, making their loss emotionally devastating. However, the emotional and psychological impact of this grief, particularly among adolescents, remains largely overlooked in academic research despite growing recognition of the human-animal bond. This phenomenological study explores the lived experiences of seven adolescent dog owners (ages 18–23) from De La Salle University Manila, focusing on understanding how they form attachments to pets, navigate caregiving responsibilities, and …

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 …

Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton Dec 2025

Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton

Theses - ALL

Accruing evidence suggests a significant relationship between sleep disturbances and disordered eating. Early adolescence is a period of heightened vulnerability for sleep disturbances and disordered eating. However, the longitudinal relationship between sleep disturbance and disordered eating remains unclear in early adolescent samples. The current study aims to examine if sleep disturbance longitudinally predicts disordered eating in early adolescents three years later, how the odds of having clinically significant disordered eating change per each unit increase in sleep disturbance, and if emotion dysregulation mediates these relationships. It is hypothesized that baseline sleep disturbance will predict greater disordered eating at follow-up, and …

Relational Knowledge Restructuring: Explored Though Experimental And Bayesian Computational Methods, Ashley Nicole Douglass Dec 2025

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 …

Hoarding And The Hoarded Home: A Phenomenological And Psychoanalytic Study, Brianna Stich Dec 2025

Hoarding And The Hoarded Home: A Phenomenological And Psychoanalytic Study, Brianna Stich

Electronic Theses and Dissertations

While research on hoarding tends to isolate hoarders from the homes they hoard and in which they live, the hoard and the hoarder share a life in the home. This study explores how hoarders live with and live through their hoard at home. It combines psychoanalysis and phenomenology within a unique methodological framework to provide a hermeneutic reading of the psychological significances of the hoarded home. In this study, the contemporary conceptualization of hoarding is historically situated and critiqued from a phenomenological perspective, and the view that hoarding is a single, behaviorally-defined syndrome that is explainable by a cognitive-behavioral model …

Accepting Vs Understanding, Transgender Aliens And Alienation, Reyna G. Aliah Dec 2025

Accepting Vs Understanding, Transgender Aliens And Alienation, Reyna G. Aliah

English

Trans people have been the subject of intense discrimination in recent years, suffering dehumanization from right-wing and conservative groups. This dehumanization (and the fear resulting from it) parallels common attitudes in science fiction about actual aliens. Orson Scott Card’s Hierarchy of Foreignness classifies individuals and species into five categories, depending on their sentience; whether they are from the same city, nation, or planet; and whether communication is possible. This paper examines how transgender people can be classified according to this system on a societal level, with said class depending on the lens used to view them as well as the …

Evaluating Joint Control Teaching Procedures For Teaching Yes-No Responding With Tact And Intraverbal Questions For Children With Autism, Desiree J. Dawson Dec 2025

Evaluating Joint Control Teaching Procedures For Teaching Yes-No Responding With Tact And Intraverbal Questions For Children With Autism, Desiree J. Dawson

Theses & Dissertations

Responding to yes and no questions is a general language skill that allows individuals to efficiently interact with their verbal community. Few behavior analytic studies have sought teaching this skill in general, with even fewer studies seeking to teach this skill when it pertains to a tact or intraverbal context. All behavior analytic studies to date seeking to teach this skill have used direct prompting and reinforcement of the yes and no responses, but there is little guidance for what can be done if this teaching strategy is not producing desired acquisition. The current experiments examined a teaching procedure informed …

Emotions As Work Material: On Dancers' Refined Use Of Affectivity, Camille S. Buttingsrud Dec 2025

Emotions As Work Material: On Dancers' Refined Use Of Affectivity, Camille S. Buttingsrud

Duquesne Studies in Phenomenology

As part of their professional practice, dancers allow their affectivity to enhance their kinesthetic work. Their intentional and disciplined use of personal, emotional resources ensures both creativity, interpretation, absorption, and connections in ways that extend beyond the traditional phenomenological understanding of affectivity as pre-reflectively based. The affective regulations dancers employ can be seen as an “artistic epoché,” and their layered performance awareness corresponds with Edmund Husserl’s descriptions of “image-consciousness.” Through qualitative interviews with three professional dancers, phenomenological theory, and additional supportive literature, this article shows how affectivity can be experienced through high-order levels of Leib, constituting states of “bodily …

Exploring The Impact Of Inpatient Mental Health Care On Adolescents, Alexandria M. Mckahan Dec 2025

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 …

Covid-19 Event Impact: Religious/Spiritual Coping And Posttraumatic Growth In Adult Female Survivors Of Childhood Sexual Abuse, Mindy Barrett Perlman Dec 2025

Covid-19 Event Impact: Religious/Spiritual Coping And Posttraumatic Growth In Adult Female Survivors Of Childhood Sexual Abuse, Mindy Barrett Perlman

Doctoral Dissertations and Projects

The COVID-19 pandemic presented a unique collective trauma that has disproportionately impacted vulnerable populations, including adult female survivors of childhood sexual abuse (CSA). This quantitative, non-experimental, correlational study examined the relationship between spiritual/religious coping and posttraumatic growth (PTG) among this population, while also exploring the psychological impact of the COVID-19 pandemic and the mediating role of religious/spiritual coping. Grounded in Tedeschi and Calhoun’s Posttraumatic Growth Theory and Pargament’s Religious Coping Theory, this study utilized the Posttraumatic Growth Inventory (PTGI), the Brief Religious Coping Scale (Brief RCOPE), and the Impact of Event Scale–Revised (IES-R) adapted for COVID-19 to assess trauma exposure, …

Beyond Additive Risk: Longitudinal Associations Between Discrimination And Positive Affect Development Among Adolescents With Single And Multiple Marginalized Identities, Vanni Jefferson V. Arcaina Dec 2025

Beyond Additive Risk: Longitudinal Associations Between Discrimination And Positive Affect Development Among Adolescents With Single And Multiple Marginalized Identities, Vanni Jefferson V. Arcaina

UNLV Theses, Dissertations, Professional Papers, and Capstones

Adolescents with marginalized identities often face chronic exposure to discrimination, a social stressor linked to a range of negative mental health outcomes. While much of the existing literature focuses on internalizing symptoms, fewer studies have explored how discrimination may disrupt the development of positive affect (POA), which is a core dimension of emotional well-being linked to resilience, identity formation, and long-term health. The present study examined how overall, race/ethnicity-based, and sexual minority (SM)-based discrimination affects longitudinal patterns of POA among adolescents with single or multiple marginalized identities. Drawing on four waves of data from the Adolescent Brain Cognitive Development Study, …

Demographic Similarity, Psychopathy, And Perceived Inherent Value: An Investigation Of Factors Influencing Moral Decision Making, Ashley Michelle Poston

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study experimentally manipulated the demographic characteristics of the subjects of moral dilemmas such that they were 20%, 40%, 60%, and 80% demographically similar to participants. Participants rated each of these individuals on a novel measure of perceived inherent value, the Perceived Inherent Value Scale (PIVS) and responded to a series of moral dilemmas using the Consequences, Norms, and preference for Inaction (CNI) model of moral decision making where the subjects of the moral dilemmas were the 20%, 40%, 60%, and 80% similar individuals. Participants rated individuals who were more demographically similar to themselves as having greater perceived inherent …

The Implementation Of Tact And Bidirectional Intraverbal Training In Teaching A Foreign Language: A Systematic Replication, Karen Parra Caballero

Seton Hall University Dissertations and Theses (ETDs)

The current study replicates and extends Yamaguchi and Matsuda (2024) to evaluate the effects of foreign tact and bidirectional intraverbal training on teaching foreign-language vocabulary to adults. An adapted alternating-treatments design was used to evaluate the effects of learning vocabulary of a foreign language through tact teaching (tacting a picture in French), foreign-native intraverbal teaching (vocalizing a French word in the presence of the Spanish word), and native-foreign intraverbal teaching (vocalizing a French word in the presence of the Spanish word). Each teaching condition had an assigned stimulus set for teaching, and an additional stimulus set was included as a …

The Sexual Assault And Violence Experiences Questionnaire: Community-Developed Items For Gathering Sexual Violence Histories With Displaced Women, Meredith A. Blackwell Dec 2025

The Sexual Assault And Violence Experiences Questionnaire: Community-Developed Items For Gathering Sexual Violence Histories With Displaced Women, Meredith A. Blackwell

Psychology ETDs

Improving measurement of sexual violence has contributed to major policy changes in the United States. However, research on sexual violence largely overlooks those exposed to conflict and displacement: a population especially at risk. Assessment measures often ignore contextual features and use phrasing that is vulnerable to underreporting. This community-based participatory research project collaborated with cultural experts from Mexico/Central America and Afghanistan to develop a preliminary item list for a self-report measure of prior sexual violence. Analysis of focus group data from 30 women revealed a range of sexual violence experiences, and provided critical phrasing used to form an item list …

Neurobehavioral Mechanisms Of Psychotic-Like Experiences And Cannabis Use, Ethan Campbell Dec 2025

Neurobehavioral Mechanisms Of Psychotic-Like Experiences And Cannabis Use, Ethan Campbell

Psychology ETDs

As cannabis use has increased steadily over the past decade, there is critical need to evaluate early cannabis use as a potential risk factor for the development of psychosis. Neurobehavioral mechanisms underlying novelty salience could clarify how cannabis exposure may influence subclinical psychotic-like experiences (PLEs). The present study leveraged dynamic functional connectivity and task-fMRI to assess the role of novelty processing in cannabis use and PLEs. A group of brain regions dynamically tied to the salience network while viewing short films were found to increase their activation as a function of stimulus novelty during a novelty bandit task. PLEs were …

Hartvigsen, Megan Hooper, Olivia Harding, Evelyn Barringer, Aditya Narayanan, Brendan Crockett, Yulia Shatalov, Paean Luby, Braden Wixted, Molly Kent, Kelly Lambert

Psychology Faculty Publications

While it is known that chronic unpredictable stress and negative events adversely affect neurobiological outcomes, much less is known regarding the neurobiological impact of positive emotions such as chronic anticipation of appetitive events. From a translational perspective, an enhanced understanding of the impact of extended exposure to positive emotions may provide novel insights into effective non-pharmacological, behavior-based approaches to enhance mental resilience. Here, we investigate a novel rodent model of chronic Unpredictable Positive Event Response (UPER) training in male and female Long Evans rats to examine behavioral, neural, and endocrine effects of enhanced anticipation of positive events. Rats were exposed …

From Trauma To Triumph: A Qualitative Content Analysis Of Posttraumatic Growth In Children’S Animated Films, Crystal Victoria Tasker

Walden Dissertations and Doctoral Studies

Children’s animated films have often been analyzed for problematic depictions of gender and cultural stereotypes, but far less attention has been given to how these narratives may portray psychological adversity and transformation. This study addressed this gap by examining how posttraumatic growth (PTG) is symbolized through the narrative arcs of ten Disney films released between 2013 and 2023. The purpose of this research was to explore how these films illustrate themes of emotional transformation, utilizing a theoretical foundation based on Tedeschi and Calhoun’s PTG model, which emphasizes five domains of growth following adversity: appreciation of life, enhanced relationships, personal strength, …
