Behavioral, System, And Informational Cyberattacks: A Human-In-The-Loop Driving Simulator Experiment, Samuel Petkac

Psychology Theses & Dissertations

Advanced technologies such as sensors and AI/ML algorithms have enabled increasing levels of automated driving system that detects, responds, and even predicts changes in a driving environment supported by wireless connectivity to nearby vehicles and infrastructure. Such connected and automated vehicles (CAVs) can be particularly vulnerable to cyberattacks targeting not only infotainment systems but also firmware and other applications, critically compromising driver safety. As we anticipate a “mixed” traffic where vehicles with various levels of automated technologies share the road for the foreseeable future, it is urgent to systematically examine types of possible cyberattacks and control human behaviors in such …

The Effects Of Covid 19 Job Demands On Public Sector Employees’ Organizational Commitment: The Mediating Roles Of Work Engagement And Job Burnout, And The Moderating Role Of Supervisor Support, Benjamin R. Kaufman

Psychology Theses & Dissertations

United States citizens rely on state government employees to provide essential public services. During the COVID-19 pandemic, these employees responded by administering both routine and novel procedures to protect public health, often placing them on the frontlines and at increased risk of contagion. Concurrently, the pandemic-driven economic downturn created budget shortfalls that threatened the job and financial security of the state workforce. Together, these conditions substantially increased job demands for state government employees.

Guided by the Job Demands–Resources (JDR) Model, this study examined how COVID‑19-related job demands influenced state employees’ work engagement, job burnout, and organizational commitment, and whether supervisor …

Exploring System Wide Trust And Dependency Behavior Within An Aviation Environment, Austin Jackson

Psychology Theses & Dissertations

The present study examined the theory of system-wide trust within the context of a multi-tasking aviation environment. Previous research suggested that unreliable automation can negatively affect a human operator’s trust in reliable automation within the same system (Rice & Geels-Blair, 2010). However, previous studies have not looked at how trust develops in the context of a multi-tasking environment, nor how different types of errors may affect trust in and the use behavior of automation. The current study employed a 2 x 2 mixed design with drone reliability (60% reliable vs 90% reliable) and error bias (false alarm vs. miss errors) …

Effect Of Physical Custody On Relationship Satisfaction In Adults, Mathew Aaron Richards

Walden Dissertations and Doctoral Studies

Custody decisions are often informed by attachment-based arguments, yet little research has examined long-term effects of custody type on adult outcomes. This study involved examining whether joint versus sole physical custody predicted relationship satisfaction, testing both parental attachment and socioeconomic status as mediators. Data were collected from 226 adult participants (mean age = 33.42), whose parents separated before age 13. Validated measures were used to assesse relationship satisfaction, parental attachment, and socioeconomic status. Participants who grew up in joint physical custody arrangements reported significantly higher relationship satisfaction compared to those who experienced sole physical custody (b = 0.54, p = …

Retrieval Interference In The Processing Of Relative Clauses: Evidence From The Visual-World Paradigm, Matthew W. Lowder, Gwynna Ryan

Psychology Faculty Publications

Although object-extracted relative clauses (ORCs) are more difficult to process than subject-extracted relative clauses (SRCs), there is still substantial disagreement regarding the cognitive mechanisms underlying these effects. The current visual-world eyetracking experiment took a novel approach to this problem by examining whether ORC-SRC differences would emerge at the matrix verb during the processing of spoken sentences containing these structures. Fixation patterns at the onset of the matrix verb revealed a tendency for participants to fixate the picture representing the subject of the sentence in both ORCs and SRCs. Crucially, participants considered the picture corresponding to a competing noun more while …

“We're Human. We Are Just Human”: Experiences Of Trans And Two-Spirit Individuals In The Midwest, Gwen Avery Donner

Honors Thesis

In the United States today, gender can be a hot button topic, seemingly controversial and assigned as political, and within conservative regions the topic of gender becomes more taboo. Unfortunately, this view can lead to the stigmatization and discrimination of individuals who fall outside of the socially constructed gender binary. In order to explore how living in the conservative landscape of the Midwest impacts individuals who reside outside of the gender binary, 11 semi-structured, qualitative interviews with Trans and/or Two-Spirit individuals were conducted in which they were asked about their lived experiences. The findings of the interviews revolved around two …

Implementing A Brief Dialectical Behavior Therapy-Informed Skills Group In A County Jail: A Mixed Methods Approach To Understanding Feasibility And Acceptability, Meaghan E. Brown

USF Tampa Graduate Theses and Dissertations

Correctional institutions unintentionally function as one of the largest mental health providers in the country. Short-term facilities, like jails, present an opportunity to provide mental health care to those who will quickly reenter our communities. Despite this, evidence-based practices and treatments in correctional settings have been implemented at slower rates compared to community settings and mental health institutions. Regulating emotions, refraining from impulsive maladaptive behavior, and communicating effectively are considered primary treatment needs among jail inmates. Dialectical Behavior Therapy (DBT; Linehan, 1993) can address these deficits and is commonly implemented in a skills training group format in correctional settings; however, …

Silent Detonations: Redirecting Focus, Preserving Identity, And Leading Under The Weight Of Microaggressions, Ray Lavan

Tapestry: Journal of Research in Education

African American educational leaders consistently navigate racial microaggressions that challenge their focus, identity, and well-being. This study explores how these leaders deploy attention to manage the emotional weight of microaggressions in K-12 public school settings. Using Gross’s emotion regulation theory and Sue’s taxonomy of racial microaggressions, this qualitative phenomenological study examines how attentional deployment serves as both a shield and constraint. Data from the African American leaders reveal that silence, background processing, selective focus, and redirection to professional goals are common strategies to sustain composure. These strategies protect leaders in the moment but create emotional strain, identity conflict, and cumulative …

Fierce Leadership-Perspectives Of Black Women Educational Leaders: A Transcendental Phenomenological Study, Janice Taylor, Dianne Reed

Tapestry: Journal of Research in Education

The authors of this transcendental phenomenological study aimed to describe the lived experiences of Black women based on their perceptions, values, and beliefs about the complexities of leadership and the kind of leadership required to succeed in their respective roles, as educational leaders. This study was framed by the adaptive leadership theory. Adaptive leadership recognizes the need for leaders to stay flexible and resilient in fast-paced environments (Nelson & Squires, 2017). The three Black women leaders in this study were fierce adaptive leaders. The information acquired from this study is significant and highlights how Black women educational leaders developed the …

Being-Their-Ship: A Presence-Based Model Of Human-Centered Leadership, Ricky J. Martinez

Tapestry: Journal of Research in Education

Being-Their-Ship describes a presence-based approach to leadership grounded in lived experience rather than positional status. Developed over years of service in rural education, the framework highlights leadership as a relational practice grounded in steadiness, quiet support, and a willingness to take responsibility for others. Drawing from autoethnography and narrative inquiry, the framework articulates four interconnected dimensions: Caring-Ship, Loving-Ship, Load-Ship, and Being-There-Ship, that define leadership not through authority but through consistent action and cultural trust. Each dimension reflects how leadership emerges when individuals become a stabilizing presence, absorb burdens that others would otherwise carry, and remain committed to a community through …

Phase Patterning In Mother-Infant Interbrain Synchrony And Its Associations With Dyadic Behaviors During Free Play, Lindsey M. Riera-Gomez

Electronic Theses and Dissertations 2020 - Present

Interbrain synchrony (IBS), or coordinated brain activation, between parents and infants is thought to support emerging social and cognitive development. Few studies have examined how neural coupling unfolds during the second year of life; a period marked by growing autonomy and complexity during play. Using functional near-infrared spectroscopy (fNIRS) hyperscanning, this study investigated mother-infant brain-to-brain synchrony during naturalistic free play interactions with a sample of 31 mother-infant dyads (12-24 months). Interbrain synchrony was examined in six cortical regions of interest (ROIs), with a focus on phase alignment. Rigorous behavioral coding captured maternal sensitivity, intrusiveness, child involvement, and dyadic relational qualities. …

The Evolution Of Self-Awareness In Conscious Organisms, Robert A. Dielenberg

Journal of Conscious Evolution

Self-awareness in conscious organisms remains an enduring puzzle for philosophers and neuroscientists. This paper proposes a tripartite evolutionary model tracing its emergence through three sequential types: the sensory self (primitive egocentric, valence-tagged awareness of sensory states), the bodily self (external objectification of the body as a distinct entity, evidenced by mirror self-recognition in select species), and the cognitive self (internal objectification of the mind enabling recursive self-transformation). Adopting a monist framework, the model treats consciousness as the biological substrate of delayed neural apperception (the “Delayed Present”), within which selves emerge as increasingly sophisticated models. It distinguishes non-human metacognition—implicit, online regulation—from …

Clinicians’ Perceived Preparedness To Support Clients Who Have Co-Occurring Disorders, Jessica A. Love Jordan, Joseph Day

Journal of Applied Disciplines

Co-occurring mental health and substance use disorders are prevalent, yet many clinicians feel underprepared to provide integrated care for this population. This study explores the factors influencing clinicians' perceived preparedness and objective knowledge in treating clients with co-occurring disorders. Data were collected from 131 clinicians using the CODECAT EZ 2.0 and TIP ZIP assessments to evaluate their competence in co-occurring disorders treatment. Results indicate that while participants held positive attitudes toward integrated care, their practical knowledge and skills were often rated as average or below. Education, clinical experience, and continuing education were found to significantly influence both perceived preparedness and …

What's That Smell?: The Effects Of Odors On Visual Reaction Times, Daniel I. Telles Orellana, Lily Smith, Elle Thompson, Ezra Koenigsberg

SPARK Symposium Presentations

Smell has long been known to be an advantageous evolutionary advantage to humans, aiding in threat detection as well as identifying potential sources of food (Brandt & Hubert, 2025). Furthermore, contemporary research additionally suggests that olfaction can regulate visual attention and help redirect cognitive and perceptual processes upon the identification of salient stimuli (Horberg et al., 2020). This indicates that both vision and olfaction can be involved in attentional capture under the correct circumstances (Fallon et al., 2020). This being said, the relationship between olfaction and maintaining visual attention is still widely unknown. The purpose of the present study is …

But Their Emails! Investigating Ideological Language Signatures In Presidential Campaign Emails And Text Messages, Jordan L. Thompson

Electronic Theses and Dissertations 2020 - Present

Although emails and text messages are important means of connecting voters with political candidates, the content of political campaign emails and text messages is understudied. The purpose of these studies is to identify linguistic patterns in candidate emails and texts from the 2024 US presidential election (Study 1) and to determine which linguistic styles are most convincing to readers (Study 2). I examined the linguistic trends in campaign emails and text messages using Linguistic Inquiry Word Count, random forests, and Structural Topic Modeling. Democratic messages had higher LIWC dictionary scores for cognitive processes and word count, providing potential evidence for …

Adaptations Of Collaborative/Therapeutic Assessment With Survivors Of Torture: Clinical Insights From Shareback Conversations, Samantha Correa

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Survivors of Torture (SoT) experience disproportionately high rates of PTSD, depression, and anxiety (Steel et al., 2009). Many SoT treatment programs use brief assessments to monitor symptoms (McFarlane & Kaplan, 2012). However, research on integrating feedback into treatment had been limited until Colpas et al.'s 2024 study on Sharebacks, a novel approach where clients review their progress with their clinician in structured feedback sessions. Given the therapeutic potential of assessment feedback (Tarocchi et al., 2013; Smith & George, 2012; Poston & Hanson, 2010) and Colpas et al.'s findings on Sharebacks' importance, this study explores how practitioners can most effectively incorporate …

Psychologists’ And Psychiatrists’ Views On Criminal Behavior, Fetal Alcohol Spectrum Disorder, And Federally Sentenced Indigenous Women In The Prairie Region And British Columbia, Rina Asghar

Walden Dissertations and Doctoral Studies

The overrepresentation of federally sentenced Indigenous women in Canada reflects longstanding structural and systemic injustices within the criminal justice system. Constituting approximately 5% of the female population, Indigenous female offenders are disproportionately represented, especially in maximum security facilities and structured intervention units. This qualitative study examined psychologists’ and psychiatrists’ perspectives on the potential role of fetal alcohol spectrum disorder (FASD) related neurocognitive impairments in increasing justice system involvement among Indigenous women in Western Canada. Guided by the multidimensional Indigenous developmental framework, which integrates historical trauma theory and attachment theory, nine psychologists and one psychiatrist were interviewed in semi-structured interviews. The …

Embodied Transcendence: Psychedelics And The Evolution Of Moral Abstraction, Emanuel Jas

Journal of Conscious Evolution

This paper explores the role of psychedelics in the context of evolutionary brain development and the conceptual capacity for moral realism. Drawing on theories from evolutionary anthropology, neuroscience, and moral philosophy, the first part provides a brief overview of human evolution and brain expansion. From here, recent empirical data from the neurosciences is assessed on the effect psychedelics have on the brain, along with speculations on the role of psychedelics in our hominoid evolutionary history—specifically, the capacity for phenomenologically rich, conscious, subjective experiences that are incredibly vivid and real. This imaginative capacity for transcendence and disembodiment could enable the realization …

Determining The Minimal Clinically Important Difference Of The 40-Item Smell Identification Test In People With Cystic Fibrosis, Eugene Oh, Jessa E. Miller, Michelle J. Lee, Anna Zemke, David Baraghoshi, Matthew J. Strand, Jeremiah A. Alt, Todd E. Bodner, Michael Chang, Naweed I. Chowdhury, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Background: Chronic rhinosinusitis(CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40-item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF-specific minimal clinically important difference (MCID) has not been established. This study aimed to determine the SIT MCID in PwCF treated with elexacaftor/tezacaftor/ivacaftor (ETI) and/or endoscopic sinus surgery (ESS). Methods: Data from three prospective, multi-institutional observational studies were pooled. Participants were ≥12 years old with confirmed CF and CRS who completed SIT at baseline and ≥1 follow-up (3, 6, 9, 12, or 24 …

Prevalence Of Contact Child Sexual Abuse Victimization In The Us: Perpetration Types And Cohort Differences, Luciana C. Assini-Meytin, Rebecca L. Fix, Yi Sun, David Finkelhor, Elizabeth J. Letourneau, Keith Kaufman, Ben Mathews

Psychology Faculty Publications and Presentations

We investigated the prevalence of contact child sexual abuse (CSA) victimization in the US by comparing perpetration types in two adult cohorts. Participants included a nationally representative sample of adults aged 18–22 (n = 3,174) and 32–36 (n = 3,237). We used weighted proportions to obtain prevalences, Rao-Scott χ2 tests to assess for differences between cohorts. Analyses were also stratified by gender. The overall prevalence was 21.7% and similar between the two cohorts; 9.7% reported abuse by adults and 16.9% by youth under age 18. Most said that offenses were perpetrated by people known to them. CSA perpetration by youth …

Executive Functioning In Schizophrenia Using A Novel Virtual Reality-Simulated Workplace: Validity, Test-Retest Reliability, And Links To Competitive Employment, Ernest Marek Tyburski, Ewa Zawadzka, Adrianna Bober, Ewa Karabanowicz, Piotr Podwalski, Jerzy Samochowiec, Anna Michalczyk, Shane T. Mueller, Michał Szelepajło, Błażej Misiak, Monika Folkierska-Żukowska, Monika Mak, Michał Harciarek, Krzysztof Wietrzyński, Ashok Jansari

Michigan Tech Publications

Virtual reality offers a promising avenue for the assessment of executive functioning in complex workplace environments. However, its use in schizophrenia remains limited. For that reason, we investigated the validity and test-retest reliability of the Jansari assessment of Executive Functions (JEF©) in individuals with schizophrenia and its associations with competitive employment. A total of 69 participants with schizophrenia and 67 healthy controls completed JEF© and standard tests. A subsample of 58 patients was retested after an 8-week interval. Individuals with schizophrenia performed more poorly than controls on JEF© (p <  0.001) and standard tests (p <  0.05). JEF© scores correlated with standard measures (p <  0.05), except inhibition tests, and with clinician-report of everyday problems (p <  0.001). Total score showed a good test-retest reliability and the practice adjusted RCI indicated 87.9% of patients remained stable over 8 weeks. In logistic regression, higher JEF© total score significantly predicted competitive employment after adjusting for age (p = 0.004) and remained significant when …

Examining The Relationship Between Burnout And Emotional Intelligence In Ministry Leaders Of Start-Up Churches, Jacquelyn Steidel-Santiago

Doctoral Dissertations and Projects

The purpose of this qualitative phenomenological study was to utilize Emotional Intelligence (EI) and burnout models to examine the relationship between perceived EI and firsthand experiences of burnout in ministry leaders of start-up churches to establish a unique connection and offer valuable insights for participants and other ministry leaders facing similar circumstances. Personal characteristics were divided into demographic information about the participants (i.e., age, race, years in ministry, congregation size, etc.) and information about the participants’ experience with specific features of burnout. The demographic information was used to identify possible factors related to various levels of EI, with the expectation …

The Psychometric Use Of Word Embeddings, Thomas Benjamin Lyle Wasden

Doctoral Dissertations and Projects

This quantitative study examined the feasibility of categorizing individuals by English-language competency using word embeddings derived from language samples obtained from these individuals and by viewing word embeddings as a psycholinguistic construct. Word embeddings have been shown to be a versatile tool for performing a large number of important natural language processing (NLP) tasks, as well as a plausible model for some processes in the human mind, including processes within the domain of psycholinguistics. This research seeks to build upon previous research by showing that word embeddings may shed light on the underlying neural representation of semantic entities being acquired …

Perceived Black Maternal Narcissism And Their Daughters’ Delinquency: Chronicles From A Daughter’S Interpretation, Nzinga Cates

Walden Dissertations and Doctoral Studies

This qualitative study examined the intricate dynamics between perceived Black narcissistic mothers and their daughters, particularly regarding potential delinquent behaviors exhibited by the daughters. By utilizing in-depth interviews with seven participants, I sought to uncover the psychological and relational factors contributing to these behaviors’ development. Thematic analysis indicated that daughters of narcissistic mothers often endure emotional neglect, manipulation, and lack of healthy role modeling. This can result in feelings of inadequacy and rebellion. Themes of identity confusion, low self-esteem, and desire for autonomy surfaced as significant contributors to the daughters’ engagement in delinquent activities. The study underscored the importance of …

Candidate Generative Ai Use In Pre‐Hire Employment Assessments: Self‐Reported Incidence And The Impact Of Warnings, Chet Robie, Timothy G. Wingate, Nataliya Baytalskaya, Hilary Butera

Business Faculty Publications

The rapid rise of generative artificial intelligence (GenAI) poses new challenges for the validity and fairness of pre‐hire employment assessments. Across two applied studies using large applicant samples completing a standardized pre‐hire assessment (which includes both cognitive and non‐cognitive components), we examined the self‐reported incidence of GenAI assistance, and the impact of warning statements designed to deter such behavior. In Study 1 (N = 5675), conducted in Q3 2024, fewer than 3% of applicants reported using GenAI, though up to 19% reported using GenAI in combination with algorithmic resources (e.g., search engines). All three warning statements (consequences, educational, and reasoning) …

Public Perception Of Risk In Missing Persons Investigations, Harry Lockett, Stefana Juncu

International Journal of Missing Persons

The current study investigated public perceptions of risk in missing person cases. A total of 271 participants were sequentially presented with five fictional vignettes describing missing individuals. Each case included a baseline description of the disappearance being "out of character" and four of these cases were paired with an additional risk factor: substance abuse, depression, dementia, or repeat missing status. The gender of the missing person was also manipulated between participants. Participants rated each case using both the standard categorical scale (Low/Medium/High) and an Extended Scale ranging from 1 to 7 and were also invited to respond to exploratory items …

‘‘If It Bleeds, Does It Lead?’: Lived Experiences Of Media Engagement For Families Of Missing Persons., Sarah Wayland Professor, Loren O'Keeffe, Syadani Riyad Fatema, Amy-Louise Byrne Dr, Elizabeth Paton

International Journal of Missing Persons

The media plays an important role in a missing persons case. Media is a powerful tool in raising public awareness and support, traversing police investigation, family liaison, and the business of media. This article reports on a focus group of seven people with a long-term missing family member, and two focus group facilitators, one of whom was also the family member of a missing person (n=9). The aim of the study was to better understand how people, who have lived experience of a family member missing, participate in media opportunities, to understand impact. Thematic analysis generated five major themes 1) …

Anhedonia Underlies The Association Between Childhood Unpredictability And Adult Ptsd Symptoms: Evidence From Three Independent Longitudinal Cohorts, Christopher Hunt, Laura M. Glynn, Elysia Poggi Davis, Tallie Z. Baram, Caroline M. Nievergelt, Giovanni Castillo, Christian Cortes, Christine Y. Chang, Dewleen Baker, Victoria B. Risbrough

Psychology Faculty Articles and Research

Background

Unpredictability in the child’s environment has recently emerged as a significant and unique form of early life adversity (ELA). Cross-sectional studies have linked childhood unpredictability with increased post-traumatic stress disorder (PTSD) symptoms in adults; however, no prospective studies have tested the link between childhood unpredictability and PTSD risk in later life, nor what processes, such as increased anhedonia symptoms, might mediate such risk. Here, we leveraged three distinct prospective, longitudinal cohorts to test the hypothesis that unpredictability during childhood contributes to adult PTSD via worsening anhedonia symptoms.

Methods

Participants were male service members (n=314), adult females (n=170), and adolescents …

Providers’ Social Determinants Of Health, Burnout, And Efficacy Addressing Patients’ Social Determinants Of Health Needs, Erik Klee

Doctor of Psychology (PsyD)

Healthcare provider burnout and the capacity to address patients’ social determinants of health are critical issues in modern medical systems. This study investigated the relationships among providers’ personal social determinants of health (Prov-SDH) needs, burnout, and perceived efficacy in addressing patients’ social determinants of health (Pt-SDH) needs. Using a sample of 149 healthcare professionals, the study examined how individual Prov-SDH factors, professional degree, clinical setting, and years of practice influenced these outcomes. Statistical analyses revealed no significant correlation between providers’ current or lifetime Prov-SDH needs and their reported burnout symptoms or Pt-SDH-related efficacy. However, results indicated that lifetime Prov-SDH needs …

Emotional Tides In The Sea Of Automation: The Interplay Of Emotions And Trust On Automation Reliance, Lei Shirase

Dissertations

The present study examined the interplay between emotions and trust in the context of automation reliance. The study investigated whether specific emotions (happiness, interest, anger, sadness, and fear) systematically impacted users’ trust in an x-ray screening decision aid, their reliance on the aid, as well as their resilience to any errors made by the aid. Despite successfully inducing certain emotional states, there was no significant relationship between emotions and trust in / reliance on the automated aid. Supplemental analyses revealed that stable individual difference traits (i.e. propensity to trust) to be a strong predictor of initial trust levels in the …
