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 …

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 …

Cracking The Code Of Ai Autonomy: Examining The Role Of Challenge And Hindrance Appraisals And Ai Literacy In Task Satisfaction, Rujuta Parekar

Graduate Studies Theses and Dissertations 2026

AI is constantly evolving and being rapidly integrated into the workplace. Limited research has examined how this integration is affecting employee outcomes, and particularly the impacts of whether employees are expected or mandated to use AI for their work. The present study utilized the challenge-hindrance framework to examine the effect of autonomy in using AI on task satisfaction through challenge and hindrance appraisal among working adults. Since the ability to understand and use AI can influence how individuals perceive it, the moderating effect of AI literacy on the hypothesized research model is also examined. A multi-wave research design 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 …

Revisiting The Foundation Of Strategic Core Theory: Informal Roles And Teamwork Roles In Work Team Centrality, Allen Thomas Shorey

Graduate Studies Theses and Dissertations 2026

Strategic core theory makes a distinction between roles within a team that are central to the team’s workflow (i.e., core roles) and those that are not central (i.e., non-core roles) (Humphrey et al., 2009). This line of work has shown that attributes, such as job-related skill of core team members, were more predictive of team performance than those of non-core members. However, this line of work has primarily examined core and non-core roles as defined by formal taskwork roles. In this thesis, I examine patient care teams and management simulation teams with the principal conviction that (a) informal roles and …

The Role Of Adolescent Attachment In The Relationship Between Trauma And Identity, Ellie Mitova

Graduate Studies Theses and Dissertations 2026

Traumatic experiences have been shown to influence identity development during emerging adulthood, a complex developmental period. However, research examining how trauma interacts with adolescent attachment qualities to shape identity processes remains limited. Previous studies have primarily focused on infant attachment styles and their long-term developmental outcomes, leaving a gap in understanding how attachment qualities developed through relationships with parents and peers during adolescence may influence identity development in emerging adults. Additionally, while traumatic experiences have been associated with maladaptive identity processes such as rumination and identity distress, some research suggests that trauma may also contribute to deeper identity exploration and …

Examining Attrition In Rtms For Smoking Cessation: The Roles Of Perceived Research Burden And Delay Discounting, Miranda Proctor

Graduate Studies Theses and Dissertations 2026

This secondary analysis examined predictors of attrition in a randomized clinical trial conducted by Roswell Park Comprehensive Cancer Center evaluating repetitive transcranial magnetic stimulation (rTMS) for cigarette smoking cessation. Smoking cessation reduces cancer risk and mortality and improves mental health outcomes. Although rTMS shows promise for supporting sustained abstinence by targeting neurobiological mechanisms underlying nicotine dependence, participant attrition threatens statistical validity, reduces power, and limits generalizability. Identifying predictors of attrition is therefore critical for optimizing trial design and retention.

Research examining predictors of attrition in smoking cessation trials remains limited. Prior work in other clinical populations suggests that higher perceived …

Examining Relationships Between Pre-Arrival Information, Perceived Preparedness, And Distressing Call Outcomes Among Firefighters, Victoria L. Steigerwald

Graduate Studies Theses and Dissertations 2026

Responding to distressing emergency calls increases firefighters’ risk for negative mental health outcomes, including posttraumatic stress disorder, warranting investigation into factors that can be targeted to reduce their risk for call-related distress. The present study examined whether the completeness of pre-arrival information about a distressing call reduced firefighters’ peri- and post-call distress via their perceived preparedness for the call and whether general self-efficacy moderated the relationship between pre-arrival information completeness and perceived preparedness. Data were analyzed from 173 active firefighters in the United States (89.0% male, mean age=37.98 years) who completed an online survey asking them to report on levels …

Virtual reality (VR) offers new opportunities for delivering psychologically meaningful conversations in digitally mediated settings. This study examined how environmental designs influence user experience during emotionally relevant self-disclosure. Fifty university students …

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 …

Healing Attachment Wounds Through Romantic Love: Exploring Narratives Of Earned Security, Ashlyn Griffith

Antioch University Dissertations & Theses

This dissertation explored how earned attachment security is experienced and developed within long-term romantic relationships through couples’ shared narratives. Using dyadic interviews, the study focused on romantic partners in which one individual demonstrated continuous attachment security while the other described a shift toward earned security over time. Although existing attachment research has examined the traits that encourage security in other relational contexts, limited research has explored the lived attachment experiences of couples or their shared understanding of how security develops within romantic love. Five long-term romantic couples participated in semi-structured dyadic interviews designed to elicit shared narratives of relationship development, …

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 …

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 …

Comparing Domain- And Facet-Based Models Of Personality Disorder: Incremental Predictive Validity And Model Fit, Alexandra Hines

Theses and Dissertations--Psychology

Personality disorders (PDs) have historically been conferred using a categorical diagnostic framework (i.e., present versus absent). However, recent research supports a transition toward dimensional models of PDs wherein personality traits are measured along a continuum. Some dimensional models contain personality domains only, whereas other models contain both personality domains and facets of each of those domains. The leading models of each type are the PD model in the eleventh edition of the International Classification of Diseases (ICD-11) and the Alternative Model of Personality Disorders (AMPD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), respectively. …

Exploring The Impact Of Pre-Assessment Rapport-Building On Children’S Evaluation Outcomes, Alyssa N. Springstead Knutz

Doctor of Psychology (PsyD)

Psychological assessment with children is vulnerable to inequities that arise from cultural mismatch, situational anxiety, and the interpretive nature of examiner judgement. This pilot study examined whether a brief, standardized pre-assessment sandtray activity could enhance children’s assessment experience and observational richness by supporting rapport prior to testing. Using a within-subjects, counterbalanced crossover design, 10 children (ages 7-10) completed two assessment sessions on separate days: one session included a 20-minute guided sandtray task immediately before testing and one session proceeded directly to testing. Quantitative outcomes included state anxiety (SAI-CH-6), general self-efficacy (GSE), and performance on brief standardized tasks (WJ-IV Math Fluency …

Let's Not Talk About Sex? Exploring Sexual Pain In Orthodox Jewish Women, Zehava Gros Schwartzblatt M.S.

Selected Full Text Dissertations, 2011-

Vaginismus, a genito-pelvic pain disorder characterized by involuntary muscle contraction that renders vaginal penetration painful or impossible, is estimated to affect between 1% and 7% of women worldwide (Laskowska & Gronowski, 2022). Although commonly conceptualized as a medical condition, growing evidence suggests that its etiology is significantly shaped by sociocultural and religious factors (Tugrul & Kabakci, 1997). In particular, belief systems that associate sexuality with immorality, sin, or shame (Cotter, 2015; Lewis et al., 2004), combined with limited sexual education, stigma, and misinformation (Nasserzadeh, 2015), may contribute to the development and maintenance of the disorder. These dynamics are especially salient …

The Adjustment Of Autistic First-Generation Students To Higher Education, Paris J. Cumba

Honors Undergraduate Theses

The purpose of the current study is to investigate how first-generation students on the autism spectrum adjust to higher education compared to their continuing generation and neurotypical peers through the lens of intersectionality. Previous research has studied how first-generation students and autistic students transition into college environments, but little research has explored how these identities intersect and affect college adjustment.

For this study, 189 undergraduate students completed a survey that measured different dimensions of college adjustment, such as academic motivation, self-efficacy, and current life satisfaction. ANOVA tests showed that there was no significant interaction between first-generation status and autism status …

Exploring What Parents And Their Twice-Exceptional Children Need From The Mental Health System, Mehrnaz Mirhosseini M.S.

Selected Full Text Dissertations, 2011-

Twice-exceptional (2e) students, defined broadly as those with both high cognitive abilities and disabilities, have unique psychological needs. Many 2e students struggle in school and at home, and their abilities and disabilities tend to mask each other, making it more difficult to diagnose twice-exceptionality (Foley-Nipcon et al., 2013). Additionally, no gold-standard interventions have been identified (Foley-Nicpon & Candler, 2018). These factors and the relative obscurity of twice-exceptionalism can leave parents feeling helpless, confused, and isolated when seeking care for their 2e child. There is no research on which mental health interventions parents believe their 2e children need, as well as …

Real Talk: Piloting A Brief Digital Body Image Intervention For College Students, Logan Faith

Research Honors

The present study examines data from 20 participants who were randomly assigned to a brief digital body image intervention and a waitlist control group. The program, Real Talk, incorporated elements from several evidence-based approaches, namely affirming one’s values, making cognitive reappraisals, building body functionality, and self-compassion. The main outcome measures were body appreciation, functionality appreciation, self-kindness, and self-judgment. We hypothesized that Real Talk participants would experience greater increases in positive body image constructs and self-kindness and lower levels of self-judgment as compared to the waitlist control group. Data were analysed using nonparametric analyses due to the small sample size. Mann-Whitney …

The Effects Of Pornography On Romantic Relationships, Jade A. Green

McNair Scholars Research

This study examined the relationship among pornography use, attitudes toward pornography, and romantic relationship outcomes among adults in the United States. The hypotheses are as follows: 1. Pornography use is negatively associated with relationship satisfaction. 2. Positive attitudes toward pornography are negatively associated with relationship satisfaction. 3. Men will report more positive attitudes toward pornography than women, 4. Higher pornography use is associated with being single.  A convenience sample of 165 adults from central Arkansas completed measures assessing pornography use/acceptance and relationship satisfaction. Statistical analyses included a correlation matrix, an independent-samples t-test, and a chi-square analysis. Results showed that pornography …

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 …

Effects Of Coaching Interventions On Burnout And Mental Health Outcomes Among Collegiate Athletes: A Meta-Analysis, Natalie Mitchell

Cal Poly Humboldt theses and projects

Studies were included if they assessed burnout, psychological well-being, or related mental health outcomes in collegiate athletes and investigated a coaching intervention. Twelve interventional studies met the inclusion criteria. Across studies, coaching interventions varied in structure, duration, sport context, and cultural setting, with most emphasizing intrapersonal strategies and emotional or mental health outcomes. Meta-analytic results indicated small, non-significant effects favoring …

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, …

The Phenomenon Of Professional Burnout Among Military Chaplains In Ukraine, Artem Makovskyi, Oleg Mateyuk, Oleksandr Bilovskyi, Anton Datskov, Dmytro Oleshko

Occasional Papers on Religion in Eastern Europe

The article presents a comprehensive study of the phenomenon of professional burnout among military chaplains in Ukraine in the context of their personal experience of being in extreme (combat) conditions. The relevance of the problem is due to the prolonged impact of combat operations, high psycho-emotional stress, and the special role of military chaplains in the system of moral and psychological support for Ukraine's security and defense sector. The theoretical and methodological basis of the study was the concept of professional burnout by K. Maslach, the provisions of the person-centered approach, and the theory of personal experience. The empirical study …

Barriers To Healthcare For Traditionally-Aged Lgbq+ College Students, Parker Long

Honors Undergraduate Theses

Seeking and receiving high-quality healthcare are key components of healthy living. Greater access to high-quality healthcare is associated with higher quality of life (Bunker, 2001). Despite the many benefits of quality healthcare, many people face barriers to accessing quality healthcare, resulting in poorer physical and mental health outcomes (Jatrana & Crampton, 2021). Individuals who identify as LGBQ+ face serious health disparities as a marginalized group. The current research was designed to examine and address these specific barriers to accessing high-quality healthcare among LGBQ+ traditionally-aged college students in order to inform ways to improve access to care. Specifically, this study investigated …

Dispositional Correlates Of Mobile Dating Application Users’ Self-Presentation Behaviors, Danielle Rafal

PCOM Psychology Dissertations

Introduction: Mobile dating applications (MDAs) have moved from niche to norm, making connecting with others easier. A problem with MDAs is the accuracy of user self-presentation. Dispositional characteristics such as personality traits, psychological distress, and age may be factors that drive MDA users’ self-presentation behaviors. This study explored whether the extent of discrepancy between deceptive and real self-presentation predicts psychological distress, whether Big Five traits enhance this prediction, and whether age group influenced self-presentation among MDA users.

Method: Using a cross-sectional quantitative survey-based design, 160 MDA users ages 18 and older residing in the United States completed the following measures: …

Increasing The Efficiency Of Screening For Severity Level Of Neurocognitive Impairment In The Corrections Sample: An Exploratory Study, Kelly Denton

PCOM Psychology Dissertations

Acquired brain injury (ABI) is a serious and potentially devastating health condition that can cause several lasting deleterious consequences affecting many domains of life. Difficulties are commonly reported in cognition, emotional, and social functioning, in addition to physical impairment. ABI disproportionally affects different groups, including the corrections population, which is five times more likely than the general population to have an ABI. However, there is limited research on the severity of neurocognitive impairment after an ABI for inmates in a correctional setting. It was hoped that the current study would help clarify the characteristics of ABI that result in different …

Examining Developmental Outcomes And Follow-Up Engagement Among High-Risk Preterm Infants In A Diverse Urban Nicu Program, Madyson Kolbes

PCOM Psychology Dissertations

Preterm infants are at elevated risk for developmental delays across cognitive, language, and motor domains, yet factors associated with engagement in NICU follow-up care remain poorly understood, particularly in diverse, urban populations. This study examined developmental outcomes at initial NICU follow-up and explored factors associated with follow-up completion among high-risk preterm infants. Participants included 174 infants enrolled in a hospital-based NICU follow-up program who completed an initial developmental screening using the Bayley Scales of Infant and Toddler Development, Fourth Edition Screener (Bayley-4 Screener). A subset of 58 infants completed a second screening visit. Binary logistic regression was used to examine …

The Influence Of Parental Attitudes On Perceptions Of Gender Socialization In Their Children, Tareva Cortes

PCOM Psychology Dissertations

Gender socialization begins early in childhood and plays a significant role in shaping children's beliefs, behaviors, and perceptions of themselves and others. Parents serve as primary agents of gender socialization and contribute to children's understanding of gender roles through attitudes, expectations, and reinforcement of gender-related behaviors. The purpose of this quantitative study was to examine parental attitudes regarding traditional gender roles, modern sexism, and children's gender-related behaviors. Participants included 163 parents and legal guardians residing in the United States who had at least one child under the age of 18. Participants completed a demographic questionnaire, the Child Gender Socialization Scale, …
