Factors That Contribute To Perceptions Of Police-Civilian Interactions, Shelby Wynne

Theses and Dissertations--Psychology

Perceptions of police-civilian interactions have been found to be impacted by the perspective in which they are viewed, with first-person perspectives eliciting negative perceptions of civilians and positive perceptions of police. However, the nature of the relationship between race and camera-perspective has not been fully explored. Black people are more likely to harmed by police at a disproportionate rate compared to White people, and consequently, have more negative perceptions of police. Three studies investigated what factors informed perceptions of police encounters, particularly when camera perspectives differed. Results showed partial support for my prediction that Black people are as not susceptible …

The Experience And Regulation Of Posttraumatic Shame Among Women With Interpersonal Trauma Histories, Jordyn M. Tipsword

Theses and Dissertations--Psychology

Posttraumatic shame – an emotion stemming from harsh attitudes about the self after trauma – is central to PTSD for many women following physical or sexual assault or abuse (interpersonal trauma [IPT]). However, knowledge of the frequency, intensity, and stability of shame in the daily lives of women post-IPT is lacking. Additionally, while some work has explored shame-specific emotion regulation (ER), or processes aimed at changing emotional responses, it remains unclear which ER strategies are effective in reducing shame, and the role of PTSD severity in shame regulation also remains unexplored. This project explored daily experiences and regulation of posttraumatic …

Hormonal Effects On Adhd Symptoms In Adolescents Across The Menstrual Cycle, Ashley G. Eng

Theses and Dissertations--Psychology

Background: Females with attention-deficit/hyperactivity disorder (ADHD) become particularly impaired during adolescence, experiencing increased rates of depression and anxiety, as well as important public and personal health outcomes like increased suicide attempts, risky sexual behavior, and substance use. However, female-specific risk factors for ADHD have been vastly understudied despite this increased impairment and comorbidity. One particularly understudied risk factor is the dramatically rising and fluctuating levels of ovarian hormones during late puberty that begin cycling monthly. In adult women, rapid decreases in estrogen levels increase risk for ADHD symptoms across the menstrual cycle, particularly for those with high trait impulsivity. Preliminary …

A Mixed-Methods Study Exploring Free Nicotine Replacement Therapy As A Strategy To Promote Tobacco Treatment Equity At Cancer Center Cessation Initiative Sites, Marguerite A. Webster

Theses and Dissertations--Psychology

Nicotine replacement therapy (NRT) is a safe, efficacious smoking cessation treatment for cancer patients; however, equitable access is limited due to insurance gaps. Offering free NRT to patients with cancer has potential to increase tobacco treatment engagement and promote equity. This mixed-methods study aims to describe how some Cancer Center Cessation Initiative (C3I) sites implemented free NRT within their tobacco treatment programs (TTPs) to inform future development of equitable TTPs. Participating sites’ (N=9) TTP and patient population characteristics were assessed via survey and analyzed with descriptive statistics. Semi-structured interviews were conducted with 16 individuals and analyzed using directed …

Fluctuations In Alcohol Impairment Of Working Memory Across The Menstrual Cycle, William Mcgarrigle

Theses and Dissertations--Psychology

Behavioral endocrinology studies in women suggest that higher circulating levels of the ovarian sex hormone estradiol (E2) may be linked to better working memory performance, especially under conditions of cognitive impairment (e.g., age-related cognitive decline). Phases of the menstrual cycle characterized by different levels of E2 may therefore influence the degree to which women are vulnerable to alcohol impairment of working memory. The current thesis used a within-subjects design to test the hypothesis that women are less sensitive to acute alcohol-induced impairment of working memory when E2 is elevated during the menstrual cycle. A sample of 75 premenopausal women completed …

Disinhibition And Bac Estimation As Predictors Of Risky Driving Behavior While Intoxicated, Sarah Heymsfeld

Theses and Dissertations--Psychology

Alcohol-related driving fatalities persist as a public health problem in the United States. Recent studies have begun focusing on driver risk-taking as a factor in DUI occurrences and consequent driving fatalities. Key factors that could contribute to risky intoxicated driving are a lack of self-awareness concerning intoxication levels and consequent risk in addition to alcohol-induced increases in the driver’s impulsivity. Fifty young adult drivers received 0.65 g/kg of alcohol (target BAC = 80 mg/dl) or a placebo in a counterbalanced order on two different days and performed a simulated driving test that measured driver risk-taking as reduced distance to other …

Cognitive-Behavioral Effects And Sex Differences In Alcohol Use, Mia Radevski

Theses and Dissertations--Psychology

Addiction models (e.g., iRISA model) suggest that excessive substance use can result in behavioral consequences such as decreased response inhibition and increased salience attribution toward alcohol cues. The primary goal of this project was to explore potential sex differences in these characteristics of addiction. This dissertation is comprised of two separate but related studies. Study 1 investigated sex differences in inhibitory control and attentional bias. The central hypotheses are 1) women who reported heavy-drinking would display greater disruptions in behavioral inhibitory control following alcohol-related cues, 2) men who reported heavy-drinking would display greater attentional bias toward alcohol-related cues, and 3) …

Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg

Theses and Dissertations--Psychology

Substance use disorders (SUDs) are characterized by repeated choices to use drugs despite adverse consequences. Value-based decision-making theory posits that choices are guided by predicted values of available options which are updated based on outcomes. Computational modeling of reinforcement learning (RL) during choice tasks has shown promise for uncovering latent mechanisms of decision-making. Recruiting people with SUD is difficult, but crowdsourcing offers an alternative for accelerating data collection. However, the validity of computational modeling using online choice task data has not been well-established. This thesis aimed to use the online crowdsourcing platform Prolific to 1) compare online and in-person choice …

Menstrual Cycle Phase And Hormonal Effects On Emotional Eating In Females With Attention-Deficit/Hyperactivity Disorder, Urveesha Nirjar

Theses and Dissertations--Psychology

Previous research has shown that cyclical fluctuations in ovarian hormones can predict changes in ADHD symptoms as well as eating behaviors, particularly emotional eating across the menstrual cycle. Previous studies have so far only examined the effects of estrogen (E2), progesterone (P4) and cycle phase in predicting individual symptoms or disorders such as ADHD or eating disorders or related behaviors separately. The aim of this study is to examine how emotional eating is influenced by naturally occurring hormonal and cycle changes in a sample overrecruited for ADHD. Seventy-eight individuals (assigned female at birth) with menstrual cycles overrecruited for ADHD provided …

Development Of A Source To Detector Simulation Of The Los Alamos National Lab Neutron Electric Dipole Moment Experiment, Dillon Buskirk

Theses and Dissertations--Physics and Astronomy

The Los Alamos National Laboratory (LANL) neutron electric dipole moment (nEDM) experiment is planning an increased precision measurement of the neutron’s permanent electric dipole moment. LANL nEDM expects to lower the statistical uncertainty to δd_LANL = 2 × 10−27 e cm after a year of live-time, which puts a more stringent upper bound on the nEDM. This statistical uncertainty is an order of magnitude less than the current best measurement set by nEDM at PSI. To reach this goal, the LANL nEDM collaboration requires a simulation tool that can tackle optimization problems, investigate systematic effects, and provide mock data …

Mediation By Fatalism Of The Association Between Symptom Burden And Self-Care Management In Patients With Heart Failure, Ashmita Thapa, Misook L. Chung, Jia-Rong Wu, Abigail Latimer, Terry A. Lennie, Gia Mudd-Martin, Chin-Yen Lin, Jessica Harman Thompson, Junghee Kang, Debra K. Moser

UK CARES Faculty Publications

Background: Clinicians and researchers often assume that symptom burden is associated with self-care management (SCM) in patients with heart failure (HF). However, that association is often not borne out in simple regression analyses and may be because another variable mediates the association. Fatalism is an appropriate candidate for mediation and is the belief that circumstances are predetermined without opportunity for control by individuals.

Objective: Our objective was to determine whether fatalism mediated the relationship of symptom burden with SCM among adults with HF.

Methods: We conducted a secondary analysis (N = 95) from a clinical trial. We used Self-care of …

Experiencing Burnout: John Henryism, Gender Role Conflict, And Anxiety Among Incarcerated Black Men, Jardin Dogan, Danelle Stevens-Watkins, Brittany Miller-Roenigk, Christopher K. Marshburn, Myles Moody

Psychology Faculty Publications

At the intersection of race and gender, Black men encounter conflicting and often stress-inducing gender norms. Research suggests Black men may utilize John Henryism Active Coping (JHAC), a culturally-relevant strategy to manage stress. However, little is known about how incarcerated Black men cope with gender role conflict (GRC) and resulting psychological distress. To better understand stressors and coping strategies among Black male prisoners, the current study examined the relationships between GRC, anxiety, and JHAC among N = 193 incarcerated Black men nearing community reentry. Hierarchical linear regression results showed length of incarceration, GRC, and anxiety were all negatively associated with …

The Short Executive Function Scale, Justin E. Karr

Psychology Faculty Publications

This study involved a psychometric evaluation of the Short Executive Function Scale (SEFS), a new 15-item self-report questionnaire measuring five constructs: Planning, Inhibition, Working Memory, Shifting, and Emotional Control. Participants included 717 U.S. undergraduate students (M = 18.9 years old, SD = 1.9; 78.8% cisgender female, 81.7% White) who completed the SEFS. A subset of 156 participants (M = 18.8 years old, SD = 0.9; 79.5% cisgender female, 83.3% White) completed the SEFS again at 2- to 3-month retest along with the Behavior Rating Inventory of Executive Function-Adult (BRIEF-A) and the Patient Health Questionnaire (PHQ-8). The five-factor model fit well …

Preliminary Evaluation Of The Scandinavian Guidelines For Initial Management Of Minimal, Mild, And Moderate Head Injuries With Glial Fibrillary Acidic Protein, Mira Keski-Pukkila, Justin E. Karr, Jussi P. Posti, Ksenia Berghem, Anna Kerttu Kotilainen, Kaj Blennow, Henrik Zetterberg, Grant L. Iverson, Teemu M. Luoto

Psychology Faculty Publications

Glial fibrillary acidic protein (GFAP) has become the most promising biomarker for detecting traumatic abnormalities on head computed tomography (CT) in patients with traumatic brain injury (TBI), but most studies have not addressed the potential added value of combining the biomarker with clinical variables that confer risk for intracranial injuries. The Scandinavian Guidelines for Initial Management of Minimal, Mild, and Moderate Head Injuries in Adults were the first clinical decision rules in the field with an incorporated biomarker, the S100 astroglial calcium-binding protein B (S100B), which is used in the Mild (Low Risk) group defined by the guidelines. Our aim …

Assessing Reliability For Quantifying Social Interactions Among Crayfish, Lee Ann Smith, Jeremy Nadolski, Grace Jacobs, Jodi M. Ogle, Madhusudan P. Srinivasan, Hannah N. Tanner, Elizabeth R. Steele, Nicole T. Marguerite, Sonya Bierbower, Slane Steen, Isaac Easterling, Abigail Greenhalgh, Cecilia Pankau, Shelby Mccubbin, Brad Behymer, Robin L. Cooper

Psychology Faculty Publications

Animal behavior is a useful way to evaluate the environment and can be a predictive tool to assess not only the effects of treatments in a laboratory setting, but also the status of ecological habitats. As invasive species of crayfish encroach on territories of native species, the social behaviors and interactions can be informative for ecological studies. For a wider and more impactful effect, training community scientists using a scoring system to record the social interactions of crayfish that includes both the level of aggression and intensity would provide useable data to monitor the environment. Amateur scientists with little training …

Ances

Psychology Faculty Publications

By age 40 years, over 90% of adults with Down syndrome have Alzheimer's disease pathology and most progress to dementia. Despite having few systemic vascular risk factors, individuals with Down syndrome have elevated cerebrovascular disease markers that track with the clinical progression of Alzheimer's disease, suggesting a role of cerebrovascular disease that is hypothesized to be mediated by inflammatory factors. This study examined the pathways through which small vessel cerebrovascular disease contributes to Alzheimer's disease-related pathophysiology and neurodegeneration in adults with Down syndrome. One hundred eighty-five participants from the Alzheimer's Biomarkers Consortium-Down Syndrome [mean (SD) age = 45.2 (9.3) years] …

Changes In Peripheral Oxytocin And Vasopressin During A Silent Month-Long Insight Meditation Retreat, Quinn A. Conklin, Anthony P. Zanesco, Brandon G. King, Elissa S. Epel, Clifford D. Saron

Psychology Faculty Publications

Background: Given its putative roles in mediating prosocial behavior, attachment bonds, and stress physiology, oxytocin modulation has been hypothesized to be a biological correlate of the salubrious effects of meditation practice. Here we investigated the effects of a month-long silent meditation retreat on changes in oxytocin, and the related hormone and vasopressin, in relation to psychosocial changes in attachment style, anxiety, personality measures, and feelings of social connectedness with fellow meditators. Methods: Plasma oxytocin and vasopressin and self-report questionnaires were measured in retreat participants (n = 28) at the beginning of, and 3 weeks into, a residential meditation retreat. Control …

Development And Validation Of A National Prostalgia Scale To Measure Acceptance And Desire For Cultural Change, Sol I. Corral, Jessica R. Bray, Daniel N. Jones, Angel D. Armenta, Michael A. Zárate

Psychology Faculty Publications

Introduction: Demographic changes occurring throughout the world, as well as different forms of climate and social movements, are examples of the constant cultural change people experience. Many of these changes reflect broad political and existential threats. We developed and tested the concept of national prostalgia, which we define as the longing of the nation’s future. According to Cultural Inertia theory, national prostalgia is a psychological propeller that facilitates acceptance of cultural change. Methods: We conducted two correlational studies to develop and test the construct, and the predictive, divergent, and convergent validity of national prostalgia by comparing it to two prospection …

Intermittent Theta Burst Stimulation And Functional Connectivity In People Living With Hiv/Aids Who Smoke Tobacco Cigarettes, Gopalkumar Rakesh, Thomas G. Adams, Rajendra A. Morey, Joseph L. Alcorn, Rebika Khanal, Amanda E. Su, Seth S. Himelhoch, Craig R. Rush

Psychology Faculty Publications

Background: People living with HIV (PLWHA) smoke at three times the rate of the general population and respond poorly to cessation strategies. Previous studies examined repetitive transcranial magnetic stimulation (rTMS) over left dorsolateral prefrontal cortex (L. dlPFC) to reduce craving, but no studies have explored rTMS among PLWHA who smoke. The current pilot study compared the effects of active and sham intermittent theta-burst stimulation (iTBS) on resting state functional connectivity (rsFC), cigarette cue attentional bias, and cigarette craving in PLWHA who smoke. Methods: Eight PLWHA were recruited (single-blind, within-subject design) to receive one session of iTBS (n=8) over the L. …

Sleep/Wake Regularity Influences How Stress Shapes Executive Function, Gabriel R. Gilmore, Anna L. Smith, Fallon B. Dickinson, Alexandra D. Crosswell, Wendy Berry Mendes, Lauren N. Whitehurst

Psychology Faculty Publications

Introduction: Sleep and stress processes shape executive function. Evidence suggests that poor sleep regulation can lead to significant impairments in executive functions. Psychological stress can also directly impact a variety of executive functions, often leading to declines, but may additionally reduce executive function via its negative impact on sleep. Rates of perceived stress and poor sleep have skyrocketed in recent years. As such, it has become increasingly important to understand how daily stress exposures and sleep processes modulate executive functions. Methods: In a remote 21-day app-based study, 227 participants completed sleep and stress assessments three times a day. They also …

Objective: The Royal Canadian Mounted Police (RCMP) Study includes longitudinal multimodal assessments of RCMP cadets from pre-training (i.e., starting the Cadet Training Program [CTP]) to post-deployment and for five years thereafter. The data allow for investigating the multidimensionality of volitional participation in digital health data collection frameworks within serial data collection platforms and the impact of participation inequalities by classifying cadets using the 90-9-1 rule. By classifying cadets as Lurkers, Contributors, and Superusers formally described by the 90-9-1 rule, where 90% of actors do not participate, 9% seldom contribute, and 1% contribute substantially allows for the assessing of relationships between …

Chinese Fintech Goes Global: Political Challenges And Business Strategies, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

Fintech (the application of digital technology to financial services) has witnessed unprecedented growth, bringing significant implications for the financial system and sustainable development.1 The Financial Stability Board, an international body that monitors and makes recommendations about the global financial system, defines fintech as “technologically enabled financial innovation that could result in new business models, applications, processes, or products with an associated material effect on financial markets and institutions and the provision of financial services.”2 The use of technology in finance is certainly not new—consider the growth of electronic banking and high-frequency trading in the early 2000s. In the past two …

The Psychosocial Aspects Of Rest, Morgan Findley

Theses and Dissertations--Kinesiology and Health Promotion

Past research in sport sciences has focused primarily on “rest” from a physical perspective, while giving limited focus to the psychosocial perspective (Eccles & Riley, 2014; Eccles et al., 2022). One major development on psychosocial rest emerged with the pioneering model introduced by Eccles and Kazmier (2019); however, further research is needed to test this proposed model with other sport/performance populations. Therefore, this study aimed to assess the model's generalizability and investigate the perceived frequency of psychosocial rest by athletes throughout their season. To accomplish this, 67 female university athletes completed an online survey comprised of questions representative of the …

An Investigation Of Body Image And Eating Behaviors In Former Ncaa Heptathletes, Claire Bailey

Theses and Dissertations--Kinesiology and Health Promotion

Research consistently supports associations between body image dissatisfaction and disordered eating pathologies in collegiate athletes (e.g., Reel & Voelker, 2012; Sundgot-Borgen, 1994). More specifically, female NCAA athletes report feeling torn between peak performance body composition and body fat levels fitting ideal feminine standards (Beckner & Record, 2016; Carson et al., 2020). Examining track and field, most event groups hold a lean-promoting perspective. However, heptathletes warrant further investigation due to the multifaceted and contradictory nature of events. Specifically, heptathletes encounter complex pressures training for a wide range of physical demands, which can create confusion in expected body types (Heazlewood et al., …

Increasing Physical Activity: Parenting Style, Parental Perceptions, And Teacher Use And Self-Efficacy, Kendra Hansen

Theses and Dissertations--Kinesiology and Health Promotion

This dissertation consists of three papers aimed at varied ways to increase physical activity for youth. The first paper reviews research on hyper-parenting and its effects on physical activity. The systematic literature review revealed that little is known about hyper-parenting effects on physical activity, but limited evidence suggests a negative relationship between the two variables.

The second manuscript examines parents’ perceptions of physical activity and its effect on their children’s academics. Results showed some minor differences between ethnic groups and those whose children are more active. Although parents tended to agree that physical activity was important, most did not seem …

Physical Education Teachers' Perceptions Of Their Pre-Service Teacher Education, Gunay Sen

Theses and Dissertations--Kinesiology and Health Promotion

Physical education plays a crucial role in fostering lifelong physical activity and contributing to the overall education of children. Effective PE teaching requires well-planned teacher education programs that align with contemporary educational standards and practices (Morgan & Bourke, 2005; Lu & Lorusso, 2016). This study addresses the gap between theoretical training and real-world teaching demands, emphasizing the need for ongoing professional development and alignment with current educational standards (Tinning, 2002; Siedentop, 1994). This dissertation explores the perceptions of physical education (PE) teachers regarding their pre-service teacher education (PETE) across four countries: Australia, England, the USA, and Türkiye. The aim is …

Effect Of On-Duty Resistance Training On Neuromuscular Function In Structural Firefighters, Jamal L. Thruston

Theses and Dissertations--Kinesiology and Health Promotion

Participation in on-duty exercise is critical to enhance firefighter safety and readiness. However, these sessions are often interrupted with emergency responses and require firefighters to work in a fatigued state that may increase injury risk. Therefore, the purpose of this study was to assess the impact of on-duty resistance training on neuromuscular function. A sample of 18 firefighters (Age: 38.8±8.0yr; Body fat: 24.9±7.0%) completed 3 testing sessions, separated by at least 72 hr to compare the effects of circuit (CT) versus heavy resistance training (HRT) fatigue on neuromuscular function. During Session 1, anthropometrics and familiarization trials of balance and neuromuscular …

Understanding Intention And Behavior Of Practicing Yoga Through The Lens Of Theory Of Planned Behavior Specifically In Rural Communities; A Qualitative Study, Shelley Meyer

Theses and Dissertations--Kinesiology and Health Promotion

While there are known health benefits for participating in yoga, little has been studied on the intention and behavior for why individuals practice yoga especially through a theoretical lens and intense qualitative thematic analysis. Targeting the rural community considers other extenuating circumstances experienced by rural residents that can impact yoga participation in rural areas. Interviews were used to gain insight into a holistic viewpoint with the rich data bringing clarity to an individual’s thought process (of intention) to incorporate yoga (behavior) in their daily life. Utilizing the Theory of Planned Behavior as the theoretical framework for developing interview questions allowed …
