Affective And Cognitive Factors Contributing To Male-Female Differences In Mathematics, Sarah N. Herod

All Graduate Theses and Dissertations, Fall 2023 to Present

Math differences between men and women have been studied for several decades, with original theories suggesting a biological reason for the differences and more new ones suggesting multiple factors, such as self-efficacy, anxiety, and spatial ability, may be responsible for these apparent differences. Additionally, most research into math differences between the sexes involves the use of a composite score, rather than examining the different sub-domains of math separately. The purpose of the current study was to examine the relationship between sex and math performance within the context of an individual's belief and attitudes towards math and spatial information. Seventy-one participants …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Exploring Public Perceptions Of Genetic Risk In Substance Use Disorders, Brooke A. Goodenow

All Dissertations

This dissertation examines genetic risk perception, with specific emphasis on substance use disorders (SUDs), through a collection of three manuscripts. The dissertation examines genetic risk perception for hereditary diseases in existing literature, describes a methodological framework for capturing genetic risk perception across social media discourse, and identifies themes and emotional tone associated with genetic risk perception for SUDs across two major social media platforms (X and Reddit).

Combined, these three manuscripts expand and support previous findings about genetic risk perception and its role in shaping health beliefs and associated behaviors. The dissertation findings reveal numerous similarities in genetic risk perception …

Leveraging Technology To Measure The Strength Of Demand For Commercial And Trafficked Sex, Michael D. Shively, Bob Rodgers, Courtney Furlong, Brooke Ruffin

Dignity: A Journal of Analysis of Exploitation and Violence

The article examines Transaction Intercept (TI), an artificial‑intelligence platform designed to reduce sex trafficking by disrupting the revenue streams that draw organized crime into the market. Transaction Intercept deploys decoy online ads that appear to offer commercial sexual exploitation or prostitution. Automated "decoy" personas connect to individuals who click on these ads and engage them in text conversations. These exchanges can remain fully automated, ending with deterrence messages, or be transferred to police for potential enforcement action or to trained volunteers who attempt to discourage further attempts to buy sex. Transaction Intercept generates extensive, real‑time data on local demand for …

Balancing War And Peace In Taekwondo Athlete Development: A Multi-Criteria Coaching Decision Support Framework Using Leadership Scale For Sports And Fuzzy Ahp, King Harold A. Recto, Hazel Jade L. Antonio, Jhyrald Anthony P. Dalida

Electronics, Computer, and Communications Engineering Faculty Publications

Coaching effectiveness is frequently evaluated through competitive outcomes, with the assumption that coaching behaviors directly influence athlete performance. This study examined the relationship between perceived coaching behaviors and individual win percentage among collegiate Taekwondo athletes using the Leadership Scale for Sports (LSS). Descriptive statistics, correlation analysis, and regression analysis were conducted across five coaching dimensions: Training and Instruction, Democratic Behavior, Autocratic Behavior, Social Support, and Positive Feedback. Results showed that none of the coaching dimensions demonstrated a statistically significant relationship with win percentage. Although coaching behaviors did not significantly predict win percentage, the findings suggest that athlete development is shaped …

How Followers Respond To Leader Differentiation: The Importance Of Considering All Leader Differentiation Properties, Yuchuan Liu, Gary John Greguras

Research Collection Lee Kong Chian School Of Business

A central tenet of many leadership theories is that leaders treat their followers differently. Although leader differentiation is ubiquitous, its effects on leaders and followers are not well understood and theory and research have not simultaneously considered its three key properties: Leader–member exchange (LMX) differentiation, LMX quality, and LMX social comparison. We developed a theoretical model in which these three properties interact to influence followers’ supervisory interactional justice perceptions and subsequently their supervisor-directed deviance and supervisor-directed organizational citizenship behaviors (OCBs). To test our model, we conducted a pre-registered experiment (Study 1), a single-level, multi-wave study (Study 2), and a multilevel, …

Navigating The Dark Side: Emotional Labor's Impact On Hr Professionals' Wellness, Esmeralda Amelia Rendón

Electronic Theses and Dissertations

This qualitative descriptive study was designed to document and describe how female-identifying human resource (HR) generalist practitioners serving as sole or primary employee relations practitioners in small- to medium-sized organizations across the United States experience and manage emotional labor in their roles, cope with its demands, and how these experiences impact their wellness and perceptions of organizational support. Despite the centrality of emotional labor (EL) in human resource professionals’ (HRPs) roles, little was known about how HRPs in these underresourced environments cope with these demands. Data were collected through semistructured virtual interviews with eight participants and analyzed using Braun and …

A Quantitative Exploration Of Public School Teachers’ Colorblind Racial Attitudes And Their Teaching Practices, Lindsey Dopheide

Dissertations

Teachers play a significant role in shaping student’s academic experiences, social development, and understanding of race and diversity within school settings. Because schools function as important sites of racial socialization, teachers’ beliefs about race may influence how they interpret student behavior, respond to inequities, select instructional practices, and engage with culturally diverse classrooms. One framework that has received increasing attention within psychological and educational research is colorblind racial ideology (CBRI) which reflects the minimization or denial of the continuing significance of race and racism in society. Colorblind racial ideology has been identified in prior literature as a dominant framework for …

A Primary Care Randomized Controlled Trial Investigating The Efficacy Of A Caregiver-Focused Prevention Program For Child Sexual Abuse, Cassandra Dukes

Dissertations

Child sexual abuse (CSA) affects 1 in 4 girls and 1 in 13 boys before the age of 18, resulting in significant long-term physical, emotional, and social consequences. Caregivers play a crucial role in preventing CSA by engaging in preventative behaviors with their children. Primary care settings may be an avenue through which to educate caregivers on their role in prevention of CSA. The present study used a randomized controlled trial (RCT) design to investigate the efficacy of a caregiver-focused educational program to prevent CSA, provided via integrated behavioral health (IBH) in a pediatric primary care setting. Participants (n=56) were …

Establishing And Validating Foundational Competencies In The Application Of Behavioral Gerontology Through Expert Consensus, Alexandra Doran

Dissertations

Behavioral gerontology continues to evolve and grow as an application of behavior analysis, but there remains a critical need to define competencies necessary for behavior analysts to provide ethical, effective care within their scope of competence. This study sought to establish and validate foundational competencies for Board Certified Behavior Analyst s® (BCBA s® ) working in this area. A mixed-methods design using three experiments was used. In Experiment 1, a review of discipline-specific competency frameworks and a job mapping process yielded a preliminary set of behavior-analytic competencies for behavioral gerontology. This produced a preliminary framework consisting of 142 competencies. Experiment …

The Effect Of Cerebellar Transcranial Direct Current Stimulation On Anxiety, Shivangi Bhardwaj

All-Inclusive List of Electronic Theses and Dissertations

Anxiety is one of the most prevalent mental health disorders in the U.S. Individuals of all ages are affected by anxiety. Therefore, research into anxiety and its potential treatment has constantly been an area of interest. Newer approaches to managing anxiety include non-invasive stimulation techniques, such as Transcranial Direct Current Stimulation (tDCS), because of its accessibility and effectiveness. Past tDCS work typically focused on regions in the frontal lobe. However, tDCS over the cerebellum has not received as much attention compared to the cerebrum, despite recent work demonstrating cerebellar involvement in emotion processing. Thus, a better understanding of how cerebellar …

What Makes A Cozy Game Cozy? Looking Through The Lens Of Feminism And 4e Cognition, Mary Catherine M. Wilcox

All Theses

Why do some games feel cozy, and others miss the mark, even if they are tricked out in bright colors and festooned with bows? This thesis examines the emerging genre of “cozy games” to better understand why some titles successfully evoke comfort and relaxation while others fail, despite relying on conventionally cute aesthetics or farming-sim mechanics. Although cozy games have grown rapidly in popularity over the past decade, the genre remains under-studied and is often dismissed as frivolous, reflecting the broader historical devaluation of media associated with women. Accordingly, this study argues that understanding cozy games requires examining women’s relationship …

When The Best-Fit Model Is Not Best: The Glass Slipper Fallacy And Latent Growth Mixture Modelling, Jonathan L. Chia, Markus Wettstein, Andree Hartanto

Research Collection School of Social Sciences

Despite the use of latent growth mixture modelling (LGMM) to study longitudinal changes, existing practices may inadvertently impede this very investigation. Although subgroup trajectories may theoretically differ in their structure (e.g., some subgroups being linear, some curvilinear), the current convention advocates overreliance on the baseline model to derive subsequent profile trajectories, which may obscure these structural differences. In this article, we provide a brief description of extant LGMM practices, after which we explicate the pitfalls of the current approach. Finally, we provide a principled approach for LGMM research moving forward. Specifically, we recommend specifying a set of theoretically plausible models …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

Caring With Ai: The Efficacy Of A Customised Chatgpt-Delivered Self-Compassion Intervention On College Students' Well-Being And Academic Functioning, Tracy Xi Chen, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

College students face various challenges, including academic pressure, social stress, and the transition into adulthood, which can lead to increased anxiety and other mental health issues. By recognizing personal struggles as part of a shared human experience and responding with kindness, self-compassion serves as a powerful strategy for enhancing resilience, facilitating better well-being and performance outcomes. Although effective, Compassion-Focused Therapy often requires substantial resources and time, limiting its applicability to college students. To overcome these barriers, the current study designed and evaluated Your Self-Compassion Companion, a ChatGPT-powered AI chatbot intervention grounded in self-compassion theory and delivered over three weekly 20-min …

Gender And Professional Identities In Businesswomen’S Negotiation, Chi-Ying Cheng, Amy J. Lim, Yi Wen Tan, Fiona Lee

Research Collection School of Social Sciences

Gender roles and expectations for women have been shown to account for why women tend to negotiate ineffectively in business settings. Drawing from the psychological literature on multiple identities, this paper examines how individual differences in perceived compatibility between gender and professional identities–captured by the construct Gender-Professional Identity Integration (G-PII)–shape businesswomen’s negotiation behaviors. Two studies examined how G-PII interacts with identity cues and cue valence to influence negotiation outcomes. We found that those who perceived their gender and professional identities as compatible (high G-PII) exhibited an “assimilation” effect–they negotiate more effectively when their professional identity was primed by professional identity …

The Ambivalent Wisdom Of Moral Disgust, Brandon Yip

Research Collection School of Social Sciences

This paper has two aims. First, to provide a positive account of moral disgust. I suggest that moral disgust is a response to acts that are socially corrosive, namely, acts that undermine the normative structure to which an agent is attuned. I support this analysis with two lines of evidence: (1) moral disgust serves the important function of guarding normative structures from socially corrosive actions and (2) the analysis provides an illuminating explanation of moral disgust in a wide variety of cases. The secondary aim of this paper is to probe the normative implications of my positive account. I suggest …

Counselors’ Training Needs In Effectively Engaging With Psychedelic-Assisted Therapy, Elif Bor

Counseling & Human Services Theses & Dissertations

As public and scientific interest in psychedelic-assisted therapy (PAT) continues to grow, counselors are increasingly encountering clients who are exploring or engaging in psychedelic use for therapeutic purposes. Such encounters introduce new ethical, clinical, and professional considerations. Counselors must develop an informed understanding of psychedelics and their effects, recognize the emotional and cognitive processes that may emerge during psychedelic experiences, and be prepared to respond to potential risks or adverse reactions (Aicher et al., 2025). They also need to competently answer client questions, assess risk and suitability, facilitate the integration of psychedelic experiences, and collaborate with medical and other professionals …

Switches And Witches: Exploring The Relationships Between Religious Struggles, Spiritual Beliefs, And Well-Being, Emma J. Trierweiler

Psychology Theses & Dissertations

This study examined the mechanisms between interpersonal and doubt-related struggles and well-being outcomes in a formerly religious sample. The focus of this dissertation was to analyze the mediating roles of disengagement from God and perceived social support. Approach toward God was also examined as a control but not specified to be connected to the well-being outcomes given the emphasis on formerly religious individuals’ experiences. This was a retrospective study, where participants were asked to consider their responses as they relate to the time they were pulling away from religion. Three measures of well-being were explored using structural equation modeling. Positive …

Retention During Turbulent Times Of Higher Education: Modeling Intent To Leave Academia For Research University Faculty, Jordan Monroe Ball

Psychology Theses & Dissertations

University faculty operate as the lifeblood of any institution given that their job requires a “double duty” to develop both scholarly research and student minds. Due in large part to these expectations, research shows a long history of poor mental health for faculty, which ultimately results in faculty turnover. One model of faculty work motivation (Padilla et al., 2023) details the way in which the faculty work environment influences their mental health, and subsequently informs their job satisfaction, organizational commitment, and intent to leave academia, which serves as a proxy for turnover. Retention related issues have not been a pressing …

Drinking Group Injunctive Norms: An Event-Level Examination, Karolina Kazlauskaite

Psychology Theses & Dissertations

College students are at increased risk for negative alcohol-related outcomes. Theoretical and empirical support suggest that peer groups play a crucial role in college student alcohol use, in part because they establish normative values and behaviors (i.e., norms) that members follow. Research indicates that those who identify more strongly with a group are more likely to embody that group’s values—particularly regarding drinking. Notably, injunctive norms, or perceptions of peer permissibility toward drinking, predict individual drinking outcomes, such that perceiving one’s peers as more approving confers additional risk for personal drinking. However, prior examinations of injunctive norms have not assessed perceptions …

Exploring The Experiences Of Women In Mental Health Therapy After The Occurrence Of Perinatal Loss, Courtney Allison Nishnick

Counseling & Human Services Theses & Dissertations

Perinatal loss encompasses losses of pregnancies at any gestational age, as well as deaths occurring within one year post-birth. In the United States, around 40 thousand stillbirths and infant deaths occur every year (Ely & Driscoll, 2025; Gregory et al., 2025), with about 23 million miscarriages also occurring annually worldwide (Quenby et al., 2021). Perinatal loss experiences lead to distressing mental health symptoms not limited to anxiety, depression, posttraumatic stress, and grief (Crockett et al., 2019; Wamser & Ferro, 2025). While there is extensive research on perinatal loss as it pertains to medical context, there is minimal research relating to …

Examining The Relationships Between Apathy Subdomains, Heart Rate Variability And Cognitive Performance, Yasmin Bahai Nabulsi

Psychology Theses & Dissertations

Apathy, defined as a reduction in motivation and goal-directed behavior, is a multidimensional neuropsychiatric syndrome encompassing behavioral, executive, and emotional components. Although heart rate variability (HRV) has been linked to depression and executive functioning, its relationship with apathy remains unexplored. The present study examined associations between apathy subtypes, resting HRV, HR and HRV reactivity, and cognitive performance. A sample of 116 healthy young adults completed self-reported measures of apathy, depression, fatigue, reward sensitivity, and attentional control. Electrocardiography (ECG) was used to assess resting HRV, followed by continuous recording during cognitive tasks, which included the Digit Span Test and a verbal …

The Effects Of Sexual Orientation Stereotype Information And Prejudice On False Memories, Source Monitoring Errors, And Social Categorization Judgments, Julia Belen Strickland Nunez

Psychology Theses & Dissertations

Minoritized groups, such as the LGBTQ+ community, receive many harmful and destructive stereotypes from others. These negative views affect minorities because when people are recalling a memory, they fill in the gaps with general information that they know. When the schematic information is not accurate, people tend to remember information that was not originally presented; this is known as a false memory. When people accurately recall a memory, but not the source of the memory, it is known as a source monitoring error.

The current study investigated whether stereotype-consistent information leads to more false memories and source monitoring errors as …

Praise That Empowers: Training Preschool Teachers To Linguistically Adapt Behavior-Specific Praise For Hispanic Students, Claudia Abril Ochoa

Dissertations

Children’s engagement in early ages is critical for promoting behavioral, academic, and social-emotional outcomes. However, engagement in classroom activities may be difficult for young children who have not mastered the primary language used in early childhood education settings (i.e., English). Research regarding engagement in English Language Learners (ELLs) in preschool settings, as well as cultural and/or linguistic adaptations of classroom interventions to serve this population is limited. Behavior-specific praise (BSP) has been an effective strategy to improve behavior in preschool classrooms. The current study used a multiple-baseline design across three Head-Start teachers to test the efficacy of in situ training …

Vulnerability In The Dark Triad: Insecure Attachment And Relational Aggression In The Peer Relationships Of College Students, Summer Boggs

Dissertations

Research on relational aggression (i.e., a type of aggression in which the aggressor harms others by damaging their relationships, reputation, and/or feelings of social acceptance) with college students has identified several important correlates, including anxious and avoidant attachment styles. Moreover, the personality traits captured by the Vulnerable Dark Triad (VDT; i.e., borderline, the antisocial component of psychopathy, and vulnerable narcissism; Miller et al., 2010) have demonstrated positive relationships with both relational aggression and insecure attachment. This study examined the relationship between insecure attachment and relational aggression among college students (N = 560), testing VDT traits as partial mediators of …

Closer Than They Appear: Parasocial Relationships, Social Processes, And Emotional Intimacy, Paige Bedore

All-Inclusive List of Electronic Theses and Dissertations

Decades of research have attempted to clarify the mechanisms underlying parasocial relationships, or one-sided relationships. Yet, relatively little empirical attention has been given to the subjective experiences of intimacy that occur in these relationships or to making direct comparisons between social and parasocial relational processes within individuals. The present study aimed to address these gaps and to investigate whether selected variables associated with social relationships similarly predicted parasocial relationship strength. Adult participants identified both a meaningful social relationship target and a parasocial target before completing measures of relationship strength, intimacy, attachment style, and cumulative exposure for each relationship type. Hypotheses …

Parent Emotion Socialization And The Influence On Child Emotion Regulation In A Clinical Sample, Crystal Tracy

All-Inclusive List of Electronic Theses and Dissertations

This study aimed to contribute to existing literature by examining parent emotion socialization (i.e., parent orientation to child emotion) and its influence on child internalizing symptoms. Prior research suggests that parent emotion socialization impacts child emotion regulation and internalizing symptoms; however, there is little research at present focused specifically on the influence of parent orientation to child emotion on child internalizing symptoms through child emotion dysregulation. This study adds to the literature by considering the association between parent orientation to child emotion and internalizing symptoms in a sample of children referred for an ADHD evaluation. Participants included 161 children ages …

The Joint Effect Of Bilingualism And Sleep On Executive Functions Among Children And Adolescents With Attention Deficit/Hyperactivity Disorder (Adhd), Yirou Jiang

Doctoral Dissertations

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that significantly impacts cognitive and behavioral functions, leading challenges for individuals across the lifespan. While extensive research has been conducted to understand the connection between executive functioning (EF) and ADHD, research findings related to the contributing factors of bilingualism and sleep still remains inconsistent (Bialystok et al., 2017). Investigating the joint effect between bilingualism and sleep on EF among children and adolescents with ADHD may help further clarify the connection between EF, language, and sleep, and facilitate the development of interventions from the perspective of these protective factors. EF encompasses cognitive processes …
