Quantified Lives: Data, Bias, And The Cost Of Categorization, Colin F. Geraghty

Dissertations, Theses, and Capstone Projects

This project critically examines how statistical methods and data visualization have historically been used to categorize, rank, and control human populations. By exploring the works of key figures like Francis Galton, Karl Pearson, and R.A. Fisher, it traces the evolution of categorization frameworks from their eugenic roots to modern applications in artificial intelligence and global metrics like the World Happiness Report. Through interactive visualizations and historical analysis, the project invites users to question the legitimacy of these frameworks and reflect on their impact on society. At its core, this work emphasizes the need to move beyond rigid classification systems, challenging …

The Psychometric Properties Of A Spanish Version Of The Attitudes And Beliefs Scale-2 Short Form In A Mexican Sample, Verónica Compeán

Theses and Dissertations

The Attitudes and Beliefs Scale 2-Short Form (ABS2-SF) is one of the most widely used measures of irrational and rational beliefs central to Rational Emotive Behavior Therapy (REBT). While evidence supports its reliability and validity in English-speaking populations, little is known about its applicability across cultural and linguistic groups. This study investigated the psychometric properties and cultural validity of the Spanish version of the ABS2-SF in a Mexican sample (n = 579) collected from undergraduate students in Tampico, Mexico, and compared them with English-speaking American non-clinical samples (n = 1,167). Using a bifactor multi-group confirmatory factor analysis (MG-CFA), I examined …

The Moderating Role Of Personality In The Relationship Between Cognitive Ability And Counterproductive Work Behaviors, Sarah Jacobsen

Theses and Dissertations

Counterproductive work behaviors (CWBs) are negative behaviors that detract from an organization’s goals and cause harm to the organization and to those involved. The current study investigated cognitive ability and personality as predictors of CWB and explored a moderating role of personality on the cognitive ability-CWB relationship. The results found no significant relationships for cognitive ability and personality with self-reported CWBs. Additionally, personality did not moderate the cognitive ability-CWB relationship. An exploratory analysis revealed significant relationships between personality and supervisor-rated CWBs, but no significant relationship for cognitive ability nor significant cognitive ability-personality interactions were found. The current study challenged previous …

Testosterone Reactivity And Parental Care Motivation In Men As A Function Of Parental Status, Nathan Boone

Cal Poly Humboldt theses and projects

Paternal investment and caregiving quality have lasting impacts on children's well-being. Children with sensitive, involved fathers typically develop more secure attachments and have fewer behavioral and psychological problems than children with less sensitive and involved fathers. While the importance of fathers’ engagement with their children is well established, the biological mechanisms that underpin paternal behavior are not fully understood. Previous research has found that baseline testosterone levels and testosterone reactivity to infant stimuli are both relevant predictors of paternal sensitivity. Short-term decreases in testosterone in nurturant contexts, and short-term increases in testosterone in challenging contexts have both been linked to …

Supervisor Support And Job Satisfaction: The Mediating Roles Of Work-Life Balance And Perceived Employability With Gender As A Moderator, Tori Lomelino

Theses and Dissertations

This study explored the relationship between supervisor support and job satisfaction, offering work-life balance and perceived employability as key mechanisms through which this relationship occurs. It also explored gender differences in the relationship between work-life balance and job satisfaction, and perceived employability and job satisfaction. Participants were full-time employees in the U.S, recruited via Prolific, who completed an online survey. While supervisor support was found to have positively influenced job satisfaction through perceived employability, the role of work-life balance was less clear. Interaction effects including gender were not significant. This study highlights the significant role of perceived employability as a …

Comparison Of Cnn And Lstm Networks On Human Intention Prediction In Physical Human-Robot Interactions, Khosro Ghorbani Zadeh, Niloofar Zendehdel, George L. Holmes, Keyri Moreno Bonnett, Amy Costa, Devin Michael Burns, Ming-Chuan Leu, Yun Seong Song

Psychological Science Faculty Research & Creative Works

Advancements in robotics and AI have increased the demand for interactive robots in healthcare and assistive applications. However, ensuring safe and effective physical human-robot interactions (pHRIs) remains challenging due to the sophistication of human motor communication and intent recognition. Traditional physics-based models struggle to capture the dynamic nature of human force interactions, limiting robot adaptability. To address these limitations, neural networks (NNs) have been explored for force-movement intention prediction. While multi-layer perceptron (MLP) networks show potential, they struggle with temporal dependencies and generalization. Long Short-Term Memory (LSTM) networks effectively model sequential dependencies, while Convolutional Neural Networks (CNNs) enhance spatial feature …

Balance Assistance Without Mechanical Support Using A Virtual Cane With Haptic Feedback, Sindhu Reddy Alluri, Sambad Regmi, Fazlur Rashid, Devin Michael Burns, Yun Seong Song

Psychological Science Faculty Research & Creative Works

Light Touch (LT) has been known to improve standing balance without mechanical support by providing sensory information about the movement of the body. Inspired by this, this work developed a Virtual Cane (VC) which gives no physical support but provides other sensory information that a physical cane would. The VC is developed with a distance sensor and vibration actuators to provide cane tip-to-ground distance information to the user. The extent to which this haptic feedback improves standing balance was assessed in a human experiment. 10 healthy young participants underwent a standing balance experiment with tandem stance and eyes closed, using …

Perceptions And Treatment Decisions For A Drug Offender Based On Social Class, Cocaine Type, Personal Characteristics, And Compassionate Love: A Vignette Study, Yasmin A. Odeh

Theses and Dissertations

Problem: The shift from a focus on rehabilitation to the more punitive, “tough on crime” approach to illegal behavior in the U.S. has been enacted in no small way by policies connected to the use and abuse of drugs. The disparities between crack and powder cocaine—two chemically similar substances—have headlined this shift (Vagins and McCurdy 2006). However, research is scarce on laypeople’s approval of deterrence approaches for drug offenses, including as a function of types (e.g., powder vs. cocaine possession). This study examined people’s perceptions of prosecutorial decisions for drug offenders—whether they are punished, rehabilitated, or both—and whether people perceived …

Pay Attention! A Comparative Analysis Of Psychological Assessments And Neurological Mechanisms For Adhd Within A Pediatric Population, Kristen E. Newberry

Antioch University Dissertations & Theses

This study evaluated the predictiveness of the WISC-V, NEPSY-II, CPT-3, and CATA when compared to each other in a sample of 272 children aged 8–16. Archival data was analyzed using binary and multinomial logistic regression models to assess concurrent validity of specific subtests and indexes. Participants were grouped by ADHD subtype (inattentive, combined/hyperactive, or no diagnosis), with gender and executive functioning measures included in the models. Findings indicated that lower Cognitive Proficiency Index (CPI) and executive functioning scores (e.g., Animal Sorting, Response Set) predicted any ADHD diagnosis compared to the no diagnosis group, whereas higher CATA scores predicted lower Inattentive …

Subthreshold Depression In The National Epidemiologic Survey On Alcohol And Related Conditions Iii (Nesarc-Iii): A Quantitative Analysis Of Prevalence, Characteristics, And Burden In A Nationally Representative Sample, Scott T. Young

Antioch University Dissertations & Theses

While subthreshold depression (subD) is relatively young for a diagnostic concept at a mere half century old, it has burdened individuals and societies for far longer. Research has established that it is a highly prevalent, clinically important entity with clear links to personal distress and impairment (including increased suicidal ideation and behavior), societal burden (e.g., increased reliance on public assistance programs), and economic costs (both personal and public). Research has also demonstrated that it represents a significant risk factor for incident major depression (MD) and that it likely represents both a prodromal and residual state in the normal course of …

A Dual Process Model Perspective On Associations Between Parent And Offspring Problem Drinking, Karallyn E. Fitisone

Theses and Dissertations--Psychology

Parental problem drinking (PPD) is a well-established risk factor for adolescent alcohol use, yet the complex mechanisms involved remain underexplored. The present study addresses this critical gap by examining how PPD, parent emotion socialization, and emerging adult problem drinking are associated within the framework of the Dual Process Model of Substance Use. Participants were 2,036 undergraduates who completed an online survey assessing PPD, retrospective reports of parental reactions to their negative emotions in childhood, and students’ current levels of problem drinking, negative urgency, negative emotional reactivity, and emotion-regulation difficulties. Structural equation modeling was used to clarify the roles of emotion-related …

ulation in the United States and Mexico.

The Relationship Between Autistic Features And Identity Development Processes Among College Students Through An Intersectional Lens, Alejandra Santana

Honors Undergraduate Theses

Research on autistic features and identity development has indicated that autistic traits are positively associated with identity disturbance (Ratner & Berman, 2015). Characteristic attributes of autism, including circumscribed interests and impairments in social relatedness, align with self-rumination and hardships engaging in the components of identity formation (Gotham et al., 2014). Nonetheless, research on this topic remains scarce. The present study analyzed the association between autistic features and identity formation processes while considering sociocultural factors, such as gender conformity and social camouflaging. A sample of college students enrolled in a large metropolitan city (N = 427) was recruited to complete …

We Know The Odds Aren't Ever In Our Favor: Toward An Understanding Of White Privilege Deprivation Amongst Black Individuals And The Initial Validation Of The White Privilege Deprivation Scale, Jennifer Burris

Theses and Dissertations--Educational, School, and Counseling Psychology

Social science scholarship acknowledges that disparities affecting Black people in the United States are rooted in historical race-based oppression (Black & Stone, 2005; Borell, Barnes, & McCreanor, 2018; Harrell, 2000; Mills, 1997). Yet little is understood about the ways Black people psychologically experience being denied the social privileges conferred upon Whites (i.e., White privilege). The belief that White privilege exists, along with the perceptions that Black people as a group are systematically deprived of benefits conferred upon Whites, could expose Black people to negative psychological and psychosocial experiences. As such, White privilege deprivation (the belief one is denied the social …

The Long-Term Psychological Effects Of Violent Crime On Victims: A Review Of Evidence And Supportive Interventions, Jayden E. Oleksyn-Lamb

Graduate Theses/Dissertations

This study utilizes anonymous survey data collected from 26 mental health professionals in various regions of Canada to understand which psychological disturbances are the most prevalent among victims of violent crime as well as which psychological interventions are most beneficial for treating violent crime victims. The data revealed that Post-Traumatic Stress Disorder (PTSD), Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), anger, guilt, self-blame, and shame are each highly prevalent. Findings also revealed that certain therapeutic methods including Eye Movement Desensitization Reprocessing (EMDR), Supportive Counselling (SC), Progressive Relaxation (PR), Cognitive Reprocessing Therapy (CPT) and Cognitive Restructuring (CR) are associated with …

Graduate And Undergraduate Quantitative Education In Psychology In The United States: A Mixed Methods Approach, Abby L. Braitman, James M. Henson

Psychology Faculty Publications

Quantitative methodology is part of the core curriculum for training in psychology and is required of graduate students across all subdisciplines; as such, the depth and breadth of course content is a universal issue among psychology training programs. Required and supplemental quantitative content is constantly evolving with the development of new techniques or applications. Therefore, the purpose of this inquiry was fourfold; we aimed to (1) describe the current state of undergraduate quantitative education and establish a common set of current undergraduate curricular topics; (2) characterize graduate quantitative education in terms of required coursework, optional coursework, and omitted topics; (3) …

Anxiety And Adaptive Functioning In Young Adults: The Moderating Role Of Psychological Flexibility, Makenzie L. Kennedy, Jeffrey E. Cassisi

Honors Undergraduate Theses

Anxiety is highly prevalent among emerging adults and is associated with impairments in academic, social, and daily functioning. While previous research has documented strong associations between anxiety and adaptive functioning, the present study uniquely tested psychological flexibility as a potential moderator that may foster resilience and adaptive coping.

Undergraduate students (N = 522) from the University of Central Florida completed measures of anxiety (PROMIS-A, GAD-7, STAI-S), adaptive functioning (WHODAS 2.0), and psychological flexibility (COMPACT-23). Confirmatory factor analyses supported distinct but correlated latent constructs of anxiety and adaptive functioning. Due to poor subscale intercorrelations, the COMPACT-23 total score was modeled as …

Living With Flying Colors: Associations Among Lgbtq+ Identity, Religiosity, Spirituality, Community, And Overall Well-Being Among Lgbtq+ Older Adults, Madison T. Diomede

Theses and Dissertations--Psychology

Experiences of discrimination and prejudice place LGBTQ+ individuals in older adulthood (i.e., 55 years old and older) at risk for poor overall well-being. This risk can be especially salient in the Southern and Midwestern U.S., where LGBTQ+ individuals enjoy fewer legal protections than in the Northeast and Western regions of the U.S. In defiance of these odds, LGBTQ+ individuals in older adulthood cultivate overall well-being through psychological-level constructs, like LGBTQ+ identity affirmation, and community-level constructs, LGBTQ+ community connection. Yet, little research has examined these avenues of strength among LGBTQ+ individuals in older adulthood. Guided by Iridescent Life Course Theory and …

The Effect Of Need For Cognition & Need For Affect On Human Reliance And Artificial Intelligence Interactions, Aliyah Mcgowan

Doctoral Dissertations and Master's Theses

Abstract

With the increased use of Artificial Intelligence (AI) automations in fields like medical diagnoses and mental health queries, there are concerns regarding an individual’s trust and reliance on the technology. Reliance on AI output may lead an individual to accept inaccurate or incorrect information without further analysis. Trust may influence reliance and trust formation may be a product of affective processing. This study investigated the relationship between Need for Affect (NFA), Need for Cognition (NFC), and trust and reliance on AI interactions. Participants were assessed on the NFA scale for willingness to approach or avoid emotional stimuli, the NFC …

Individual Participant Data Meta-Analysis Of Single-Case Experimental Design Data: A Comparison Of Bayesian And Restricted Maximum Likelihood Estimation, Yukang Xue

Electronic Theses & Dissertations (2024 - present)

Two-stage individual participant data (IPD) meta-analysis can be used to synthesize intervention effects from single-case experimental design (SCED) studies with multilevel modeling. However, various challenges exist at both stages, including standardizing the intervention effect size, accounting for autocorrelation, and estimating the between-study and between-case variances. While both restricted maximum likelihood estimation (REML) and Bayesian estimation can be used to estimate model parameters, REML has been more commonly applied despite the potential advantages offered by Bayesian methods. Moreover, no methodological studies have focused on Bayesian estimation in the context of meta-analysis of SCED studies, let alone when IPD meta-analysis (often recommended …

Exploring Mental Health Concerns And Loneliness Among East Asian International Students In U.S. Universities, Shihan Xu

Antioch University Dissertations & Theses

This study examined the unique stressors encountered by international college students, with particular attention to East Asian international students, whose collectivistic cultural values contribute to their mental health status and reported symptoms. Following the COVID-19 pandemic, the rise in stress levels and loneliness highlighted the need for further examination. Using data collected in 2024 through the Counseling Center Assessment of Psychological Symptoms-34 (CCAPS-34) and the UCLA Loneliness Scale, the study surveyed East Asian international students enrolled in universities in the United States to identify prevalent mental health concerns and explore the correlation between loneliness and self-reported symptoms among East Asian …
