Development Of The Negative Attitudes Toward Nonbinary Individuals Scale, Jenna Sue Lehmann

Tennessee State University Alumni Theses and Dissertations

Research within the field of psychology examining the experiences of transgender individuals and prejudice toward transgender individuals has increased in recent history alongside the conscious awareness of transgender individuals within the United States. The research that has been conducted has primarily focused on transgender individuals broadly as a group on binary transgender individuals. As, such measures of prejudice toward these groups have been developed and validated. Although the study of nonbinary experiences and prejudice is developing, there has been no extant measure of prejudice toward nonbinary individuals specifically. A measure of prejudice toward this group is needed to (1) examine …

Influence Of Parental Approval And Disapproval On Interracial Relationship Outcomes, Stefanie Boakye

Tennessee State University Alumni Theses and Dissertations

Interracial couples may encounter unique challenges in their relationships due to negative perceptions such as racial prejudice, discrimination, disapproval, cultural stereotypes, and opposition from society and family. These challenges can be especially difficult when the disapproval comes from their parents. This study explored how perceived parental approval influences interracial romantic relationship outcomes, specifically relationship satisfaction, commitment, and closeness. Data were collected from individuals in interracial relationships (N ≈ 80) using the Relationship Assessment Scale (RAS), the Investment Model Scale (IMS), the Relationship Closeness Inventory (RCI), and the Parent-Adult Child Relationship Questionnaire (PACQ). A multivariate analysis of variance (MANOVA) was conducted …

The Impact Of Supervisor Cultural Humility On The Supervisory Working Alliance Among International Trainees, Fanchen Gao

Tennessee State University Alumni Theses and Dissertations

Supervisor cultural humility has been theorized to contribute to stronger supervisory working alliances (SWA), yet limited research has examined its role within multicultural contexts involving international trainees. Guided by the Multicultural Orientation framework, this study explored whether supervisors’ cultural humility predicted the quality of the supervisory working alliance, whether the relationship differed based on participant role (supervisor or trainee), and whether international trainees’ cultural backgrounds influenced their perceptions of the SWA. The sample included 72 participants from counseling and psychology training programs in the United States, consisting of international trainees and clinical supervisors. Participants completed an online survey assessing cultural …

Journal of Youth Development

Out-of-school time learning occurs in a variety of settings including formal-learning environments, such as afterschool programs, or informal-learning environments, such as museums or youth clubs. Educators in out-of-school time contexts serve diverse youth populations. Many educators often have limited experience or preparation in how to support STEM learning, particularly with learners experiencing diverse physical and/or sensory abilities, such as mobility, dexterity, vision, or hearing. The purpose of this article is to share research-to-practice strategies for STEM in out-of-school time settings for professionals working with youth experiencing diverse physical and/or sensory abilities. These strategies are derived from a review of available …

Consumption Of Negative Media Content Mediates The Association Between Levels Of Trauma Exposure And Insomnia Severity In Hispanic Young Adults, Michiyo Hirai, Laura L. Vernon

Psychological Science Faculty Publications

Research has shown that individuals who have experienced traumatic events are at greater risk of developing severe insomnia than those without trauma. Further, according to the stress sensitization hypothesis, victims of multiple traumas, compared to those who have experienced a single trauma, are particularly vulnerable to severe insomnia. One potential mechanism underlying the association between trauma experiences and insomnia is media exposure. Although avoidance behaviors are symptoms of posttraumatic stress, victims of traumas also demonstrate attentional bias toward threats and difficulty disengaging attention from threats. These cognitive tendencies may result in heightened vigilance to negative media content, particularly trauma-related content, …

Examining The Influence Of Encoding And Retrieval Contexts On 2- To 4-Year-Olds' Acquisition Of Nouns And Verbs, Piper Swearengin, Patrick Mihalicz, Leah Marsh, Zoe Baker, Faith Perry, Susan A. Graham, Jane B. Childers

Psychology Faculty Research

This study investigates whether the context in which a word is learnt affects noun and verb learning. There is mixed evidence in studies of noun learning, and no studies of background perceptual context in verb learning. Two-, three-, and four-year-olds (n = 162) saw a novel object moved in a novel way while hearing four novel words, either nouns or verbs. They were asked to generalize the word to a similar action or object shown in the same or different context. Results demonstrate that 2- and 3-year-olds were more accurate at test when learning nouns than verbs, demonstrating that verb …

Stay Woke: Understanding Critical Consciousness Development In Adults And Its Relationship To Psychological Constructs, Christin Alexandra Mujica

Graduate Theses and Dissertations

Racism confers numerous measurable health risks for people of color. Interventions to mitigate the impact of racism on health are necessary and important to reduce disease burden and improve health outcomes for people of color. While communities of color have developed resiliency tactics that have allowed them to survive, even thrive, in the face of racial oppression, the evaluation and promotion of promising tools that counteract racism’s negative impacts are essential (Phillips et al., 2015). Critical consciousness is just such a tool. Research with children suggests it holds promise (Diemer et al., 2016; Heberle et al., 2020; Maker-Castro et al., …

Rumination And Inhibitory Control In Suicidal Ideation: The Role Of Explicit And Implicit Emotional Processing, Arooj Abid

Graduate Theses and Dissertations

Suicide is the tenth leading cause of death in the United States, and suicidal ideations (SI; thinking, considering, or planning suicide) are a strong predictor of suicide attempts. Prior literature describes inhibitory control as an important facet of regulating negative thoughts, and studies suggest that inhibitory control deficits and engagement in brooding rumination are risk factors of SI. Recent studies have found implicit cognitive markers of suicidality suggesting that level of processing may variably be linked to SI. This study examined the relation between aspects of inhibitory control across explicit and implicit emotional contexts and levels of brooding rumination among …

Designing An Experiment To Create And Evaluate Behavioral Changes In Air Force Pilots' Fuel Efficiency, Jackson Macias

Theses and Dissertations

Fuel represents over 70% of the logistical resupply demand within the Department of Defense, with the United States Air Force accounting for most of that consumption. While prior fuel efficiency efforts have primarily focused on technical upgrades, this research explores how behavioral interventions can influence pilot decision-making and operational energy outcomes. Using the Theory of Planned Behavior (TPB) as a guiding framework, this study investigates the effects of targeted behavioral strategies on pilots’ attitudes, subjective norms, perceived behavioral control, intentions, and actual fuel-efficient behaviors. A quasi-experimental design was applied through a controlled pilot study using simulator flights. Six participants were …

Qualitative interviews were conducted with mental health emergency service users to better understand the experience of using mental health emergency services, garner critical feedback of the service, and explore recommendations to improve future response. A total of 23 participants conducted interviews and detailed 40 incidents of mental health emergency service utilization. These interviews were then coded and analyzed. There were a few major findings from the data. Just over …

Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

“Justice, Justice Pursue”: Coworker Reactions To Religious Workplace Accommodations, Joshua A. Nagel

Dissertations, Theses, and Capstone Projects

This study examines coworker reactions to religious accommodations in the workplace, a growing necessity as religious diversity increases, and recent legislation strengthens protections for religious observances. Religious accommodations can provoke perceptions of differential treatment, impacting coworker morale, cooperation, and organizational cohesion. While extensive research exists on disability accommodations, religious accommodations differ fundamentally as they often relate to moral beliefs and are viewed variably in terms of necessity and controllability. Drawing on organizational justice theories, this dissertation applies and modifies Colella’s (2001) and Colella et al.’s (2004) models for coworker perceptions of distributive and procedural fairness of disability accommodations to the …

Characterization Of The Attentional Profile In Women And Girls With A Fragile X Premutation Allele, Shira Russell-Giller

Dissertations, Theses, and Capstone Projects

The fragile X premutation (PM), characterized by 55 to 200 CGG repeats in the FMR1 gene, is associated with diverse clinical outcomes, including cognitive and neuropsychiatric changes. Despite most individuals with a PM presenting without overt clinical symptoms, adults face increased risks for conditions associated with a PM, including higher rates of attention and executive difficulties. This dissertation investigates the developmental trajectory of attention and executive functioning changes in females with a PM using a series of prospective studies employing the Attention Network Test (ANT). Study 1 re-analyzed prior data on sustained attention in women with a PM, revealing significant …

The Interaction Of Multilingualism And Depressed Mood On Cognitive Set-Shifting, Annalise Caviasco

Dissertations, Theses, and Capstone Projects

Although findings are mixed, many researchers believe there are cognitive benefits to multilingualism, a phenomenon dubbed the “bilingual advantage”. Of these apparent benefits, cognitive flexibility, or the ability to shift thinking styles based on the context or specific demands of a certain situation, is thought to be highly relevant. Current literature suggests that one aspect of multilingualism, the practice of “code-switching” between languages throughout their daily lives, is related to increased general cognitive flexibility compared to monolinguals. Another branch of research on cognitive flexibility investigating the role of affect in cognition demonstrates that clinical depression as well as transient negative …

Non-Linear Heart Rate Variability: Investigating Cardiac Complexity Of Psychopathic Traits, Khaya A. Roach

Dissertations, Theses, and Capstone Projects

Psychopathy is a complex personality disorder characterized by distinct emotional and interpersonal deficits, and affects approximately 25% of the prison population and 4.5% of nonincarcerated populations. The manifestation of psychopathy can be understood through two distinct variants, each demonstrating unique etiological pathways and clinical presentations. Primary psychopathy is characterized by core interpersonal and affective deficits, including shallow emotions and manipulativeness, while demonstrating reduced autonomic responsivity and lower anxiety levels. Secondary psychopathy presents with higher levels of impulsivity, anxiety, and emotional dysregulation, showing stronger associations with various psychopathologies. Treatment outcomes also vary between the variants, with primary psychopaths typically showing poor …

Unveiling The Precision Of Physiological Signals In Prediction Error During Fear Learning: Insights From Associative Strength And Generalized Uncertainty, Haja H. Jallo-Jamboria

Dissertations, Theses, and Capstone Projects

Prediction error (PE) is the discrepancy between expected and actual outcomes. It is a central mechanism in associative learning particularly within fear-conditioning paradigms. Identifying physiological markers of PE in aversive contexts has important implications for refining learning models and enhancing clinical interventions for anxiety-related disorders. This study examined skin conductance response (SCR) as a potential physiological index of PE by analyzing both anticipatory and omission-related responses across multiple learning phases. Participants completed a Pavlovian fear-conditioning paradigm in which two conditioned stimuli (CS+) signaled threat at different reinforcement probabilities: CS+100 (certain threat) and CS+50 (uncertain threat), alongside a non-reinforced safety cue …

Improving The Assessment Of Functional Ability In Older Adults, Aneela Rahman

Dissertations, Theses, and Capstone Projects

Deficits in instrumental activities of daily living (IADL) are a hallmark of dementia, and the unprecedented aging of the population strongly motivates early identification of older adults at-risk for functional decline. In 2015, the White House Conference on Aging emphasized the need to improve detection of diminished capacity across important areas of functioning. To date, there is very limited research on early IADL changes in cognitively unimpaired (CU) individuals and those with subjective cognitive decline (SCD) and mild cognitive impairment (MCI), who may be in early preclinical dementia stages. Additionally, little is known about how changes in functional brain networks …

Endocannabinoids Mediate Racial/Ethnic Discrimination Prediction Of Posttraumatic Stress Disorder Symptoms Moderated By Resting-State Functional Connectivity In Black And African American Individuals, Emily A. Albertina, Lucas Torres, Garrett Sauber, Cecilia J. Hillard, Jacklynn M. Fitzgerald, Terri A. Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background

Individuals from marginalized ethnoracial groups face higher risk for posttraumatic stress disorder (PTSD) symptoms, exacerbated by experiencing racial/ethnic discrimination. Previous work separately explored the endocannabinoid (eCB) system and functional connectivity response to stress/trauma and suggested that experiences of chronic minority stress, such as racial discrimination, contribute to eCB tone and resting-state functional connectivity. We explored how circulating eCB tone, in conjunction with resting-state connectivity, contributes to increased risk for PTSD symptoms following trauma among individuals experiencing discrimination.

Methods

Black/African Americans (n = 74; mean age = 33.81 years) were recruited from a level 1 trauma center. Correlational and …

Exploring The Lived Experiences Of Former Lagos State Male Public High School Teachers About Their Onboarding Process., Agboola Clement Ikuyinminu

Walden Dissertations and Doctoral Studies

Lagos State, Nigeria, faces male teacher retention challenges in public high schools, including destabilizing the educational environment, reducing the availability of experienced mentors, and negatively impacting student performance and outcomes. School leaders need to understand the challenges leading to male teacher turnover. The purpose of this qualitative phenomenological study was to explore the lived experiences of Lagos State male public high school teachers who left the profession, focusing particularly on their perceptions of onboarding and reasons for leaving the profession. This study was grounded in Herzberg’s two-factor theory, Bauer and Erdogan’s onboarding theory, Maslow’s hierarchy of needs, and Bandura’s social …

Preparation, Development, And Refinement Of The Interview Protocol In Qualitative Research, David C. Coker, Adebowale Akande

The Qualitative Report

Interview protocols are by far the most common method utilized in qualitative research data collection. Novice and experienced researchers, from working on dissertations to grant proposals or other publications, often lack detailed interview design methods, as many educational programs do not require specific coursework on interview protocols and question development. To improve qualitative research, we make a proposal to incorporate an interdisciplinary approach that operationalizes three stages: preparation, development, and refinement. Preparation involves mapping the extant literature to define broad, narrow, and focused topics to write actionable standards, goals, and objectives. Development uses instructional design and educational psychology to construct …

Development And Validation Of The Attitudes Toward Algorithms Scale: A Universal Scale To Measure Individuals Attitudes Toward Algorithmic Decision-Making, Nikolai Bock, Astrid M. Rosenthal-Von Der Pütten

Human-Machine Communication

Algorithmic decision-making (ADM) has become increasingly important across various fields, ranging from personal entertainment to criminal justice. While existing research has predominantly explored evaluative outcomes like individuals’ perceptions and interactions with these systems, there remains a significant gap in understanding the underlying mechanisms that lead to these outcomes. Building on traditional behavioral intention theories, we identified attitudes toward algorithms and ADM as crucial determinants. In response to the lack of an appropriate measure for this construct, we developed and validated the Attitudes Toward Algorithmic Decision-Making Scale (ATAS), a novel instrument designed to assess core beliefs that drive attitude formation toward …

Socio-Technical Exchange With Machines: Worker Experiences With Complex Work Technologies, Cameron W. Piercy, Reaia Turner-Leatherman

Human-Machine Communication

Machines are now commonplace work partners and Human-Machine Communication (HMC) is part of modern work. Guided by the machine heuristic and Social Exchange Theory (SET) this paper uses interviews with 22 workers to explore the socio-technical relationships between humans and machines at work. Participants worked with complex machines across a wide variety of industries and roles and findings reveal participants see machines as part of the work ecosystem, develop everyday machine heuristics to guide repeated interactions with machines, and that elements of human uniqueness persist in evaluations of humans and machines. Discussion points emphasize situated and developing human-machine interaction scripts, …

Development Of Respiratory Sinus Arrhythmia In Young Infants With Autism Spectrum Disorder, Preterm Birth, And Typical Development, Jessica Bradshaw, John E. Richards, Julia Yurkovic-Harding, Eilis Mclaughlin

Faculty Publications

Respiratory sinus arrhythmia (RSA) is a key index of parasympathetic function and environmental adaptability. Lower resting RSA has been linked to preterm (PT) birth in infancy and autism spectrum disorder (ASD) in childhood, yet RSA across the first 2 years in young infants born PT or later diagnosed with ASD remains unknown. This study examined resting RSA and mean interbeat interval (IBI) development from 1 to 24 months in infants at varying ASD likelihoods, including infant siblings of children with ASD and those born PT. A longitudinal design tracked resting RSA and mean IBI in 137 infants from 1 to …

Does Spirituality Mediate Or Moderate The Adverse Effects Of Occupational Stressors On Mental Health In Law Enforcement Officers?, Erika D. Keplinger

Doctoral Dissertations and Projects

Law enforcement officers are often exposed to occupational stressors that can negatively affect their mental health and job performance. Spirituality has been thoroughly researched as a restorative method to improve physical and psychological health concerns. There has also been an increase in studies on workplace spirituality. The existing research on workplace spirituality suggests that incorporating spirituality into the workplace increases employee well-being and decreases stress and burnout. Unfortunately, research on police culture often neglects spirituality. There is little research to show how spirituality could mediate or moderate the adverse effects of mental health on law enforcement officers. This quasi-experimental, cross-sectional, …

Is The Misdiagnosis Of Adhd And The Use Of Ritalin Related To Delinquent Behaviors And Problems With Social Anxiety Disorder In Young Boys?, Michael A. Cooper

Doctoral Dissertations and Projects

Attention-deficit/hyperactivity disorder (ADHD) diagnoses are increasing at a rapid rate. Young boys are known to be very energetic, inattentive, and lack the attention needed to function well in school or other venues, and based on these attributes, they often have a higher rate of diagnosis of ADHD than girls. The purpose of this quantitative, non-experimental, comparative study was to assess the validity of retrospectively examining ADHD misdiagnosis and associated Ritalin use. Specifically, how proposed childhood misdiagnosis of ADHD was related to delinquent behaviors and social anxiety in adolescence and adulthood was examined. Results showed over half of the participants (n …

Missionary Kids And Ptsd And Spirituality, Sabreena S. Massey

Doctoral Dissertations and Projects

In recent years, studies have documented the importance of spirituality in assuaging psychological distress. Numerous studies have investigated the connection between post-traumatic stress disorder (PTSD) and spirituality and its positive outcomes among diverse populations. A diverse population that is insufficiently addressed in the literature is missionary kids (MKs). Further, studies investigating the relationship between spiritual struggles and PTSD among MKs remain under-researched. Moreover, while studies document the existence of mental health disorders among MKs, a formal investigation examining PTSD symptomology among MKs had yet to be conducted. For this study, participants were recruited via purposive and snowball sampling, and 81 …

Exploring The Lived Experiences Of Adults With Personality Disorders Arising From Childhood Trauma: Understanding The Connection Between Childhood Trauma And The Development Of Personality Disorders In Adulthood, Patricia Osei Sarpong

Doctoral Dissertations and Projects

Childhood trauma is one of the key factors that influences the development of personality disorders in adults. Even though there is a wealth of quantitative evidence linking early trauma to later mental health issues, there is still a great deal of uncertainty about the lived experiences of persons who had experienced such trauma and gone on to develop personality disorders. By examining these individual accounts, this study aimed to contribute to a more thorough understanding of the ways in which childhood trauma impacted personality development and contributed to the onset of personality disorders. In this study, 20 individuals, aged 20 …

The Moral Identity Of School Shooters As Perceived By Impacted Community Members: A Qualitative Study, Danielle Caprice Rand

Doctoral Dissertations and Projects

This qualitative study investigated the moral identity of school shooters as perceived by impacted community members. The existing literature lacks agreement on the root cause of school shootings and has been unable to provide a unified identification of school shooters. Discussed throughout school shooter research was the lack of a moral identity in school shooters. Further, research on moral identity has not covered one specialized group of individuals: school shooters. Moral identity, the mien of an individual’s moral thoughts and behaviors, was researched as a potential predictor of school shootings. This study employed a case study research design and used …
