Examining Executive Functions And Semantic Organization Across Occupation Types, Emily Murtha

PCOM Psychology Dissertations

This study examined the relationship between executive functioning, semantic organization, and occupational classification, focusing on whether individuals in professional roles (as defined by the Career Occupational Preference System; COPS) demonstrated stronger executive functioning and semantic organization during memory recall than those in non-professional roles. Participants completed the Booklet Category Test (BCT) to assess executive functioning, the California Verbal Learning Test–Second Edition (CVLT-II) to evaluate semantic organization using short-delay free recall (SDFR), and the Wechsler Adult Intelligence Scale–Fourth Edition (WAIS-IV) to measure IQ. Results showed no significant associations among the main variables. While higher BCT performance was linked to greater use …

Exploring Psychological Impacts, Coping, And Conflict Resolution Of Transnationalism On Parent-Child Relationships, Sally Sanchez

PCOM Psychology Dissertations

The number of immigrants migrating to the United States has increased over the past 30 years. Many of these immigrants leave behind their spouses and children, creating transnational families. Researchers have focused on the experiences of transnational families, but there is a need for continued research to further explore the psychological impact of separation and reunification. The purpose of this study was to identify the possible psychological impact of the separation and reunification process experienced by transnational families, and the coping strategies used during the process. This study used a qualitative design to explore the experiences of transnational families who …

Sex-Dependent Changes In Risk-Taking Predisposition Of Rats Following Space Radiation Exposure, Elliot Smits, Faith E. Reid, Ella N. Tamgue, Paola Alvarado Arriaga, Charles Nguyen, Richard A. Britten

Department Radiation Oncology & Biophysics Faculty Publications

The Artemis missions will establish a sustainable human presence on the Moon, serving as a crucial steppingstone for future Mars exploration. Astronauts on these ambitious missions will have to successfully complete complex tasks, which will frequently involve rapid and effective decision making under unfamiliar or high-pressure conditions. Exposure to low doses of space radiation (SR) can impair key executive functions critical to decision making. This study examined the effects of exposure to 10 cGy of Galactic Cosmic Ray simulated radiation (GCRsim) on decision-making performance in male and female rats with a naturally low predisposition for risk-taking (RTP) prior to exposure. …

A Two-Hit Model Of Executive Dysfunction: Simulated Galactic Cosmic Radiation Primes Latent Deficits Revealed By Sleep Fragmentation, Richard A. Britten, Ella N. Tamgue, Paola Arriaga Alvarado, Arriyam S. Fesshaye, Larry D. Sanford

Department Radiation Oncology & Biophysics Faculty Publications

Future Artemis-class missions to Mars will expose astronauts to prolonged space radiation (SR), sleep disruption, and operational demands requiring greater autonomy, placing decision making and executive function at heightened risk. Both SR and sleep fragmentation (SF) independently impair cognition, yet their combined effects remain poorly understood. Using the Associative Recognition Memory and Interference (ARMIT) task, we assessed cognitive performance in male rats exposed to 10 cGy of Galactic Cosmic Ray simulation (GCRsim), SF, or both. Under well-rested conditions, GCRsim-exposed rats exhibited overt deficits in the C.1.2 stage, performing at chance when reinforcement contingencies shifted, consistent with impaired cognitive flexibility. In …

The Lived Experiences Of Fathers With Transgender Children Under 18 In States Banning Gender-Affirming Care, Ashley Perez

Dissertations and Theses

Parents of transgender individuals can experience numerous stressors in accessing overall care and support for their child's health and well-being. Parents can also undergo significant personal growth and change because their child is transgender. Unfortunately, the majority of the current literature focuses on mothers' experiences with transgender children. This study advances knowledge that can further support families navigating life with a transgender child, as the lived experiences of fathers are greatly lacking. Furthermore, the political and environmental scope in which the family is located can impact what families face when accessing care and support for their child and can result …

Childhood Betrayal Trauma And Suicidal Ideation: The Role Of Early Maladaptive Schemas And Interpersonal Problems, Christine Yost

Dissertations and Theses

Betrayal trauma (Freyd, 1996) is a specific form of trauma that occurs when a child is significantly harmed by someone they depend on or trust. Prior research has demonstrated that betrayal trauma is more strongly associated with adverse mental health outcomes than traumas lower in interpersonal betrayal, yet few studies have examined its relationship with suicidal ideation or identified mechanisms that explain this association. The present study tested a path model in a sample of 391 young adults aged 18-34 who endorsed suicidal ideation in the past year. The model examined whether specific early maladaptive schemas (emotional deprivation, social isolation/alienation, …

Cleansing Our Recycling Failures: How Guilt And Outrage Lead To Different Types Of Pro-Environmental Behavior, Cody D. Packard

CGU Theses & Dissertations

Most Americans view recycling as “the right thing to do,” yet U.S. recycling rates lag behind other developed countries, and Americans are quick to justify why they do not recycle more (e.g., laziness, inconvenience). Recent messaging has highlighted recycling failures in the U.S., but how effective are these messages, and do they create individual behavioral changes? According to research on moral self-regulation, failing to act morally can threaten a person’s moral self-concept, eliciting moral emotions (i.e., guilt and outrage), and motivating compensatory behavior (such as increased recycling). Three studies examined whether watching a video about poor recycling in the U.S. …

Shall I: Do The Motivations For Breakup Sex Differ Across Different Scenarios?, T. Joel Wade, Zoe Macuto

Faculty Journal Articles

This research investigated endorsement of the 4 motivators (relationship maintenance, ambivalence, hedonism, miscellaneous) for engaging in breakup sex across three relationship breakup scenarios, i.e., a breakup occurred due to: general reasons, infidelity, and being in a long distance relationship using an online questionnaire with a primarily White, primarily heterosexual sample (n = 304, Mage = 20.67). Results indicated that women are more likely than men to engage in breakup sex for relationship maintenance reasons when the breakup is due to general reasons, and for a long distance breakup scenario, non-heterosexuals engage in breakup sex for relationship maintenance reasons, and overall …

The Influence Of Familial Nudging On Attitudes Toward Climate Change And Monetary Contributions: An Exploration Of Ease And Difficulty With Evidence From Japan, Canada, The Usa, And Norway, Hidenori Komatsu, Hiromi Kubota, Kenji Asano Asano, Yu Naga, Catherine Salmon, David Widman, Elisabeth Oberzaucher, T. Joel Wade, Leif Edward Ottesen Kennair, Maryanne L. Fisher, Rebecca Burch, Ryoko Takikawa, Samara Rice

Faculty Journal Articles

Climate change countermeasures require monetary investment for implementation through regulations, often in the form of public taxes. Therefore, public opinion on climate change is an important factor in achieving carbon neutrality (CN). How public perception is formed, leading to motivation to fund measures for CN, needs to be identified. This study aimed to identify the causal structures of attitude change leading to financial investment through two surveys in multiple countries using nudging messages emphasizing familial support (familial nudging), which is effective in promoting pro-environmental attitudes. Study 1 (2023) examined how familial nudging moderates risk-averse attitudes toward climate change. Despite successful …

The Power To Commission: Exploring The Evaluation Capacity And The Transformative Role Of Evaluation Commissioners In The International Development Sector, Ann Marie Castleman

CGU Theses & Dissertations

Evaluation commissioners play a central role in evaluation practice by generating demand for evaluation through issuing calls for evaluation services and managing evaluation contracts (Lemire, Nielsen et al., 2018; Nielsen et al., 2018b), particularly in the international development sector. Yet few competency sets specify the knowledge and skills needed to conduct this work. Even less is known about the evaluation marketplace in the international development sector and the contract mechanisms used to procure evaluation services.

This research explored the capacity to commission evaluation among international nongovernmental organization (INGO) evaluation commissioners, including individual competencies and practices for commissioning an evaluation, factors …

Traditional And Non-Traditional Behavioral Tests Demonstrate The Attenuation Of Cognitive Deficits By Therapeutic Hypothermia In A Rat Model Of Neonatal Hypoxic-Ischemic Encephalopathy, Angela Saadat, Cortney Kaszowski, Haree Pallera, Frank Lattanzio, Richard A. Britten, Asna Sulaiman, Stephanie Newman, Alireza Hosseini, Tushar Shah

Department of Pediatrics Faculty Publications

Introduction: Neonatal hypoxic-ischemic encephalopathy (HIE) is neurological disease caused by the deprivation of oxygen and blood flow to the brain during the developmentally-critical perinatal period. Therapeutic hypothermia (TH) is the standard of care treatment for HIE, though cognitive deficits can persistent throughout life despite treatment. The nature of these deficits, and the impacts of TH and sex are not well understood, and this presents a key barrier in the development of novel therapeutics.

Methods: The goal of this study was to enhance the characterization and measurement of cognitive outcomes with tasks that measure spontaneous behaviors in a rodent models of …

Optimal decision-making requires consideration of internal and external contexts. Biased decision-making is a transdiagnostic symptom of neuropsychiatric disorders. We created a computational model demonstrating how the striosome compartment of the striatum constructs a context-dependent mathematical space for decision-making computations, and how the matrix compartment uses this space to define action value. The model explains multiple experimental results and unifies other theories like reward prediction error, roles of the direct versus indirect pathways, and roles of the striosome versus matrix, under one framework. We also found, through new analyses, that striosome and matrix neurons increase their synchrony during difficult tasks, caused …

Therapy-Based Strategies To Support Tummy Time In Infants Post-Hospital Discharge: A Scoping Review Protocol, Ketaki Inamdar, Sonia Khurana

Rehabilitation Sciences Faculty Publications

Tummy time is essential for infant development, yet many caregivers face significant challenges with adherence due to behavioral and contextual barriers. While numerous tummy time interventions exist, a limited understanding of their behavioral components hinders effective replication and implementation. This scoping review aims to identify multidisciplinary interventions used to promote tummy time in infants aged 0–12 months, evaluate their impact on adherence, developmental and health outcomes, and examine the behavior change techniques employed using the Theoretical Domains Framework (TDF). Following the Joanna Briggs Institute (JBI) methodology, a comprehensive search will be conducted in MEDLINE (PubMed), Web of Science Core Collection, …

The Effect Of Need For Closure, Gender Essentialism, And Contact On Transphobia, Jacob E. Vargas

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Using a motivated social cognition framework, this study explores whether there is an indirect effect of need for closure on transphobia via gender essentialism and whether this relationship is moderated by transgender contact. Data were collected from an undergraduate sample of 405 cisgender participants (n_men = 159, n_women = 246). A simple mediation and a moderated mediation were used to examine the hypothesized relationships, controlling for participant gender. Results reinforced the positive correlation between gender essentialism and transphobia and the negative correlation between transgender contact and transphobia. However, the mediation and moderation hypotheses were not supported. Need …

Examining Trauma And Substance Use Co-Morbidity In African Americans, Breanne Maray Sande Russell

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Childhood maltreatment (CM) is a profound public health crisis that significantly elevates the risk for substance use disorders (SUDs), including alcohol and opioid misuse. Adolescents exposed to CM are especially vulnerable, often turning to substances as maladaptive coping mechanisms during critical developmental periods. African American youth bear this disproportionate burden, yet research addressing their unique experiences remains strikingly limited. Furthermore, while the co-occurrence of trauma-related disorders and substance use is well documented, racial and ethnic minority groups continue to be underrepresented in this literature. Emotion regulation difficulties are increasingly recognized as a mechanism linking PTSD symptoms with substance use, yet …

Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation investigates how echo chambers emerge on social media by shifting the lens from aggregate patterns of information exposure to moment-by-moment, individual level interaction decisions between peers. I theorize that selective exposure online is not only about what content people consume or avoid, but also about selective social exposure—accepting, rejecting, or sharing with the sources of that content—guided by sociopolitical identity, ideological distance (ID), and discrete emotions. To test this, I employ two survey experiments using real tweets varying in ideological extremity and measure user’s likelihood to Block, Follow, Retweet, or reply, alongside self-reported emotional reactions and ID between …

Improving Adherence In Adolescent Kidney Transplant Recipients, Kaylen Munoz

Nursing | Student Research Posters

Background: Adolescent and young adult (AYA) kidney transplant recipients face unique challenges in maintaining long-term graft function and overall health. Nonadherence to immunosuppressive therapy and difficulties transitioning from pediatric to adult care contribute to the increased risk of graft failure in this population. Despite proposed tools identifying adherence barriers, there is a lack of implementation and targeted interventions addressing the barriers AYA transplant recipients face. Purpose: This study aims to evaluate the effectiveness of a structured transition program that utilizes an adherence barrier tool and adherence-promoting interventions in improving health outcomes for adolescent and young adult (AYA) kidney transplant recipients. …

The Impact Of Parental Mental Health On Infants In The Neonatal Intensive Care Unit, Andee L. Plaskett

Nursing | Student Research Posters

The neonatal intensive care unit (NICU) provides critical and life saving care for infants born with medical complications that may need specialized care. The NICU environment can be an overwhelming and stressful place for both parents and infants. Parental mental health challenges, such as stress, anxiety, and depression, can significantly impact infants in the NICU by hindering parent infant interaction and connection. Parental mental distress is often linked to an increase in anxiety for the infant, as well as higher rates of medical complications and a higher likelihood of longer hospital stays for the infant. Parental stress can have a …

These challenges contribute to poor health amongst vulnerable populations which highlights the importance of using culturally sensitive and trauma-informed care. Objective: This research aims to test whether culturally adapted, trauma-informed nursing care improves disclosure of abuse and access to support services. The objective is to strengthen safety and trust between healthcare providers and patients through culturally sensitive care. Method: A quantitative quasi-experimental …

The Psychosocial Effects Of Chemotherapy On The Adolescent Population: Implementing Community Building Programs, Kareena Jakhu, Princess Kyra R. Anicete

Nursing | Student Research Posters

Background: During the adolescent stage (13-18), individuals go through role confusion and seek much of their validation from their fellow peers. Forming a strong sense of community is crucial in this stage of development as it helps with creating a foundation for who they want to become. Chemotherapy strips this aspect of socialization due to its ability to suppress the immune system. When socialization is taken away, adolescents face loneliness, which greatly impacts their development. Purpose: The purpose of this research is to look into the adolescent population undergoing chemotherapy and help them aid the lack of socialization caused by …

The Effects Of Strong Social And Parental Support Compared To Low Or Absent Support In Lgbtqia+ Youth Mental Health, Kassandra Bautista

Nursing | Student Research Posters

Throughout history, sexual and gender minorities have faced a range of emotional and psychological challenges shaped by their unique experiences and interactions with society, family, and peers. According to the American Psychiatric Association (APA), homosexuality was classified as a sociopathic personality disturbance in the first edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-I) in 1952, and it remained listed as a mental disorder until it was removed in 1973. Individuals that identified as lesbian, gay, bisexual, transgender, queer, or other identities within the LGBTQIA+ community were historically seen as abnormal and were often subjected to ethically problematic …

Quality Of Remotely-Collected Gaze Data In Autistic And Non-Spectrum Children, Rhiannon Luyster, Taylor Boyd, Amelia Steele, Thuy Buonocore, Catherine Sancimino

Emerson Authors, Researchers, & Creators

Many developmentalists have shifted to remote research. This project uses secondary data to evaluate the quality of eye-gaze data from 30 autistic children and a language-matched sample of 30 nonspectrum children (mean ages 48 and 27 months, respectively). All children completed an experimenter-moderated preferential looking paradigm via Zoom. Frequency of co-occurring child and household events, rates of missing data, and percent agreement between gaze coders were assessed. Results indicated that co-occurring events were minimal, with no diagnostic group differences. Missing data rates were low overall and were unrelated to diagnostic group, age, or language level of participants; however, higher rates …

Using Brief Acceptance And Commitment Training To Increase Psychological Flexibility And Reduce Stress In School-Based Professionals, Rayna Yaeger

All Graduate Theses, Dissertations, and Other Capstone Projects

The significant behavioral and mental health concerns of students and staff in public schools within the United States has led to an increased risk of stress and burnout in teachers, which may lead to subsequent physical and mental health related concerns for staff and negative educational outcomes for students. Due to these school-based concerns, action should be taken to meet the needs of staff and students. This study aimed to better understand the effect of brief, group-based ACTraining on teachers’ psychological flexibility, general stress, job-related burnout, and social validity by replicating and extending the findings of Gillard et al. (2021) …

Development Of A Swpbis Fidelity Tool For Front-Line Intervention Agents, Courtney A. Sowle

All Graduate Theses, Dissertations, and Other Capstone Projects

SWPBIS is a commonly used EBP that provides a continuum of support across three tiers of prevention (Farkas et al., 2012; Mercer et al., 2017). It is known that implementation of SWPBIS with high levels of fidelity has resulted in positive outcomes for students within that system (Farkas et al., 2012). While systems may report high fidelity of implementation of SWPBIS within their system, these reports may not be representative of how an evidenced-based practice (EBP) is implemented by frontline intervention agents and instead is likely more representative of the subjective perceptions of PBIS team members and external coaches (Reinke …

Surveying Teaching Rewards For Effective Behavior Management, Maggie M. West-Johnson

All Graduate Theses, Dissertations, and Other Capstone Projects

This study investigated the implementation of teacher reward systems within School-Wide Positive Behavioral Interventions and Supports (SWPBIS) in K–12 educational settings. While the PBIS framework has been extensively studied for its impact on student behavior and academic outcomes, limited attention has been given to supporting and motivating educators through systematic reward systems. This research aimed to identify the types of teacher rewards used, methods of selection and distribution, and staff perceptions of effectiveness and social validity. Using a structured 39-item survey distributed to SWPBIS team members across eight schools in Minnesota, the study gathered quantitative and qualitative data on current …

Psychological Contract Breach And Institutional Trust In Higher Education: Extending The Triadic Framework, Hannah E. Blodget, Katelyn R. Raborn, Justin Travis, Susan Ruppel

University of South Carolina Upstate Student Research Journal

Psychological Contract (PC) theory, originally developed in organizational contexts, has increasingly been applied to higher education to understand the expectations and obligations that students perceive in their relationships with institutions. In this context, the PC refers to the unwritten set of mutual expectations and perceived obligations that shape the student-university relationship (Rousseau, 1998). Psychological contract breaches (PCB), or perceived failures to fulfill promised obligations, can undermine student trust, engagement, and institutional commitment. Despite growing interest, research on PCBs in higher education remains sporadic, often limited to cross-sectional designs, single relational targets, and inconsistent measurement approaches. Moreover, most studies focus on …

A Dog Tail: To Trust Or Not To Trust, Victoria A. Denishchich, Christa C. Christ

University of South Carolina Upstate Student Research Journal

Trust plays an important role in relationships and social functioning while also influencing communication, cooperation, and emotional well-being. Previous research has found that dogs enhance social relationships, approachability, and perceptions of safety and friendliness in everyday interactions. However, not much is known about how the effect dogs have on perceptions of trust applies when photographs are used. Such info is essential given the amount of online social interaction that occurs in society today. This current study examined whether the presence of a dog in a photo affects our trust levels in strangers. In Study 1, 74 participants viewed photos of …

A Phenomenological Look At Mental Blocks In Artistic Gymnastics, Lauren M. Rogers

Theses and Dissertations

Mental blocks are a poorly understood but pervasive and challenging phenomenon in artistic gymnastics that are characterized by a disconnect between the mind and body and an interference with athletes’ ability to physically perform previously automatic skills. This study used interpretive phenomenological analysis to explore the lived experiences of female D-I collegiate gymnasts in the United States who have struggled with mental blocks, examining the characteristics, causes, and management strategies through semi-structured interviews. Findings suggest that mental blocks are best understood on a spectrum and are difficult to attribute to a single cause as they often stem from a combination …
