How Disgust In Germ Averse Individuals Biases Avoidance Decision-Making, Wesley Stuart, Timothy Schoenfeld Phd

Science University Research Symposium (SURS)

The present study investigates the relationship between germ aversion and avoidant decision making. Individuals in the general population who rate highly in germ-aversion and disgust sensitivity may act maladaptively in order to avoid potentially anxiety inducing scenarios. If encountered, these scenarios will cause an increase in physiological arousal and a suppression of salivatory cortisol in the individual. We hypothesize that this stress response biases decision making in an avoidant manner. Participants for this study, consisting of 60 undergraduate students at Belmont University, started by taking a perceived vulnerability to disease scale. Then, those in the experimental group performed a task …

Neurocognitive And Momentary Assessment Of Fear-Based Mechanisms Underlying The Transition From Partial To Full Remission In Anorexia Nervosa., Caroline Christian

Electronic Theses and Dissertations

Background. Anorexia nervosa (AN) is a serious psychiatric illness, with high mortality, chronicity, and societal costs. Many individuals with AN that are weight restored do not to fully remit from cognitive-affective symptoms (e.g., fear of weight gain) maintaining the disorder, contributing to the poor outcomes. This critical stage of AN is called partial remission. AN is characterized by high levels of fear and avoidance, which may prevent full remission; however, the role of fear-based mechanisms (i.e., fear approach; avoidance) in partially-remitted AN remains untested. Methods. In the current study (N = 55 partially-remitted AN), participants completed two behavioral paradigms …

A New Direction For Public Understanding Of Science: Toward A Participant-Centered Model Of Science Engagement., Christopher Rickels

Electronic Theses and Dissertations

Engaging the public with science is not an easy task. When presented, scientific findings, public health recommendations, and other scientific information filter through the personal values, beliefs, and biases of members of the public. Science communicators must contend with these differences in order to be effective in cultivating a public understanding of science. Given the importance of scientific understanding for living well in a complex world, increasing science understanding through science engagement is imperative. The field of public engagement with science is dichotomized by a public information deficit approach and a contextualist approach. The deficit approach prizes the factual content …

Age-Related Differences In The Relationship Between Activity Familiarity And Well-Being., S. Kelly Shryock

Electronic Theses and Dissertations

Background and Objectives: This study explored age-related differences in the relationship between activity novelty/familiarity and well-being, conceptualized within theories including Selection, Optimization, and Compensation (SOC), Self-Determination Theory (SDT), and Socioemotional Selectivity Theory (SST). For all ages, participation in activities has been shown to enhance well-being. Known mediators of this relationship include psychological, physical, and psychosocial benefits. It is less clear what types of experiences are optimal across the lifespan. Research Design and Methods: A online cross-sectional, correlational study (N= 200) was conducted. Measures included demographic data, ratings of three self-identified recent activities, three activity choices of familiar or …

Changing Public Perception Of Dementia: The Effect And Credibility Of Three Informational Models., Diana Hedrick

Electronic Theses and Dissertations

Background: Since the 1970s, Alzheimer’s disease and dementia have been portrayed in a medicalized, symptom-focused manner to help spread awareness, improve diagnosis, and push for treatment research. In recent decades, there has been movement towards a biopsychosocial, person-centered approach that considers social and psychological factors that interact with biological diseases processes. Common biopsychosocial approaches retain an emphasis on deficits and symptoms. New research has integrated positive psychology constructs and dementia. This integration of positive psychology principles and dementia care and research has the potential to more accurately capture the experience of having dementia. Objectives: This dissertation tested how the portrayal …

Assessing Non-Motor Symptoms In Parkinson’S Disease Using A 6-Hydroxydopamine Lesion In The Substantia Nigra, Tiffany Aguirre

Psychology Theses - Archive

Motor symptoms within Parkinson’s disease (PD) are some of the most well-researched areas, whereas there remains an extensive gap in the literature researching non-motor symptoms, which include sleep, mood, pain and cognitive impairments to name a few. It is well-known that PD affects the brain by depleting dopamine within the nigrostriatal pathway, specifically targeting the substantia nigra, which plays a vital role in producing and controlling motor movements. However, the substantia nigra, as well as dopamine, also play a role in reward and motivation and yet there is still little research done to assess how the degeneration of dopamine within …

A Multiple Case Study To Understand How Students Experience Science And Engineering Practices, Chris Schaben, Justin Andersson, Christine Cutucache

Department of Educational Psychology: Faculty Publications

The Next Generation Science Standards (NGSS), amid recent shifts in science curriculum, call for students to learn science through the practices of scientists and engineers (science and engineering practices, or SEPs). SEPs, related to inquiry learning, are ways students learn science content by doing science. Students have varied experiences learning science and engineering practices, including exposure in the classroom, from media, and in science fairs. Using a qualitative, multiple case study design, we analyzed public school educators’ and middle and high school students’ (ages 12–18) interview transcripts about learning through the science and engineering practices. Findings demonstrate that students learn …

The Effect Of Aphantasia On Visual Memory Retention, Joshua M. Bain

Longwood Senior Theses

Aphantasia is the inability to create mental imagery which affects approximately 2% of people in the world (Zeman et al., 2015). The vividness of visual imagery questionnaire (VVIQ) was used to sort participants into four groups (aphantasia, low, medium, and high vividness) based on their vividness score with aphantasia participants scoring a 16 (the minimum). I tested the effect of aphantasia on scores of a visual memory recall test. Participants saw two of six possible images and answered five questions per image. Analysis of the results did not show any significant difference between aphantasia and non-aphantasia scores on the recall …

The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes

Master's Theses

This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Executive Functioning In Children And Adolescents With Type 1 Diabetes : Associations With Hba1c, Glycemic Variability, And Household Income, Victoria Louise Ledsham

Legacy Theses & Dissertations (2009 - 2024)

Type-1 diabetes mellitus (T1DM) has been repeatedly linked to executive functioning (EF) deficits in children and adolescents but the mechanisms underlying this association are not well understood. Chronic hyperglycemia — frequently measured as glycosylated hemoglobin A1c (HbA1c) levels — and increased glycemic variability have both been proposed as risk factors for EF difficulties in this population, but it is unclear whether they each uniquely reflect T1DM-related risk for EF deficits. Furthermore, few studies have considered interactions between glycemic factors and family-level risk factors in shaping children’s EF development. Particularly, household income may exacerbate risk associations between HbA1c or glycemic variability …

The Effects Of Endogenous And Exogenous Progesterone On Ingroup Affiliative Bias, Abby Sibson

Psychological Science Undergraduate Honors Theses

Millions of women use hormonal contraceptives around the world and though the physical side effects are thoroughly described in the literature and clinical setting, the psychological effects have been largely ignored until recently. Recent studies have found that the use of hormonal contraceptives has an effect on women’s hormones and psychological well-being. The goal of the present research was to expand the current knowledge of the effect of hormonal contraceptives on women’s hormones and social behavior by examining how women with differing levels of progesterone due to menstrual cycle fluctuations (follicular or luteal phase) or using hormonal contraceptives (birth control …

Examination Of The Relationship Between Loneliness And Binge Eating Symptoms, Kimberly Stevens

UNLV Theses, Dissertations, Professional Papers, and Capstones

Loneliness is implicated in several mental health conditions and may also be linked to eating pathology, like binge eating symptoms (e.g., loss-of-control eating). However, the pathways by which loneliness might be associated with binge eating symptoms are less well understood. Preliminary evidence suggests perceived stress may be a key explanatory pathway. Specifically, perceived stress mediates the impact of loneliness on other mental health outcomes and is associated with increased risk of binge eating symptoms. This study investigated relationships between loneliness, perceived stress, and binge eating symptoms and tested whether heightened levels of binge eating was accounted for by increases in …

Trauma And Crisis Counselor Preparation: The Relationship Of An Online Trauma And Crisis Course And Counseling Self-Efficacy, Julia Leigh Lancaster

Counseling & Human Services Theses & Dissertations

The field of trauma and crisis is growing and ubiquitous to all counseling specialties. Updates in 2009 and 2016 to the Council for Accreditation of Counseling and Related Educational Programs (CACREP) counselor preparation standards added mandated teachings on crisis, trauma, and disaster counseling in counselor preparation programs’ (CPPs) curricula. Since then, some CPPs have created stand-alone crisis courses, while the majority have infused various related content and trainings into already established counseling courses. Research does, in fact, support an increased crisis, trauma, and disaster readiness with more hours dedicated to the study and practice of domain specific content, and confirms …

Neurotypes: Do Ocd, Adhd, And Autism Play A Role In Life Satisfaction?, Morgan Mcleod Evans

Honors Theses

OCD (Obsessive Compulsive Disorder), ADHD (Attention Deficit Hyperactivity Disorder), and ASD (Autism Spectrum Disorder) are neurotypes that impact every aspect of life, including daily activities and socialization, which is why they have been shown in prior studies to negatively impact life satisfaction. This study compared the levels of life satisfaction now and before the COVID-19 pandemic in young adults (n = 324) with typical neurotypes, those with only ASD (autism), with only OCD, with only ADHD, with two of the neurotypes, and with all three neurotypes. Contrary to predictions from prior research, life satisfaction did not decrease after the onset …

Faith-Based Counseling Versus Traditional Psychotherapy: A Phenomenological Evaluation Of African American Protestant Experiences, Shannon Gray

Dissertations

This phenomenological study was designed to evaluate the experiences of African American Christian adult clients within traditional psychotherapy and faith-based counseling settings. Research has shown various therapist/counselor identities affect Christian African American clients, and that Christians as well as African Americans have historically been less likely to pursue traditional psychotherapy for a variety of reasons. Participants were six African American Christian adult participants (three traditional psychotherapy participants and three faith-based counseling participants). All participants were asked open-ended questions about their experiences in traditional psychotherapy or faith-based counseling. In addition, they were asked to evaluate several aspects of their therapy/counseling experience …

Prenatal Opioid Use And Neonatal Abstinence Syndrome: A Review Of The Neurophysiological, Neuropsychological, And Behavioral/Emotional/Social Impacts In The Pediatric Population, Candice Gore

Dissertations

The opioid epidemic over the past two decades has raised concerns regarding the developmental fetal impact of prenatal opioid use. Research in this area continues to grow, but largely has focused on treatment for neonates experiencing withdrawal symptoms postnatally. Long term clinical implications for this at-risk population have not been studied extensively leaving many gaps in research and highlighting the need for future empirical studies. This literature review will examine the neurophysiological, neuropsychological, and the behavioral/social/emotional impacts on infants, toddlers, and school aged children who were prenatally exposed to opioids with or without the diagnosis of neonatal abstinence syndrome. Providing …

Lifestyle Choices Related To Food Consumption And Their Relationship To Depression, Steven L. Jennings Jr.

Dissertations

Dieting, or the act of restricting oneself to small amounts or particular kinds of foods on the basis of health, spirituality, lifestyle, and moral decisions, is a practice that dates to 1066 A.D. However, with social media being as influential as it is, one might believe dieting is a new obsession or at least an obsession to which popular culture is returning. Despite this, it is only in recent years that researchers have begun to focus on the health benefits of such behaviors. The present study was designed to take this focus a step further by exploring the potential risks …

The Intersection Of Religion And Mental Health Help-Seeking: Themes Within Youth Experiencing Early Psychosis, Breanna Nichols

Student Theses

Little research has examined the intersection of religion and mental health among predominantly conservative communities – where religion tends to weigh heavily. It is known from the literature that religion and spirituality play a role in influencing treatment pathways and views towards mental health. The primary aim of the present study was to explore via secondary thematic analysis, the intersection of religion and mental health within a conservative Midwestern community of youth who are receiving treatment for early psychosis, with a secondary look at family dynamics. Seven participant transcripts were analyzed from the Narrative Enhancement and Cognitive Therapy-Young Adult (NECT-YA) …

Emotion Identification Ability And Perspective-Taking In Children With Autism Spectrum Disorder, Ana Lucia Garrido Huerta

Theses and Dissertations

Autism spectrum disorder (ASD) is characterized by persistent deficits in social interaction. Perspective-taking and emotion identification are important skills to develop appropriate social interactions. Previous research has shown that children with ASD may lack the ability to relate emotionally to others. Research has also shown a deficit in perspective-taking skills in children with ASD. The selected studies reviewed in this thesis analyze seven articles that show research on children with ASD regarding their emotional identification and perspective-taking skills. Articles searched under the words “emotion identification,” “perspective-taking,” and “autism” obtained from the Psychology and Behavioral Sciences Collection using the EBSCO database …

The Mediating Role Of Gun Attitudes In The Association Between Dsm-5 Posttraumatic Stress Disorder Symptom Clusters, And Gun Ownership In Young Hispanic Adults With Exposure To Interpersonal Trauma, Vanessa Gonzalez

Theses and Dissertations

Despite growing interest in gun attitudes and gun ownership among United States citizens, the current body of literature is limited and tends to focus on white non-Hispanic individuals. The present study examined the effect of interpersonal trauma-related PTSD symptoms on gun attitudes and protective gun ownership. The associations between experiencing PTSD symptoms, gun attitudes, and protective gun ownership were examined in a sample of 176 young Hispanic adults (n = 127 women, n = 49 men) with exposure to interpersonal trauma. Specifically, the mediating role of positive attitudes towards guns in the associations between the four clusters of DSM-5 …

Further Validation Of The Realness Scale: Are Celebrity Worshipers Unreal?, Lynn E. Mccutcheon, Lillian Donahue, Joshua L. Williams, Sarah K. Nielson, Scott Peterson, Terry F. Pettijohn Ii

Psychology: Faculty Publications

We administered the Realness Scale (RS), Celebrity Attitude Scale (CAS), and the modified Authentic Living Subscale (ALS) from the Authenticity Scale (AS) to undergraduate students from four American institutions of higher learning. We sought to further validate the RS by showing that it correlated positively with the ALS and negatively with the CAS. We also hypothesized that African Americans would score lower than Whites on the RS. Our results supported the first hypothesis, but we found only weak or non-existent support for the other two hypotheses. Discussion focused on reasons why our latter two hypotheses yielded mostly negative results and …

Coping Strategies And Self-Compassion As Protective Factors In The Infant And Early Childhood Mental Health Workforce, Megan Wolff

Electronic Theses and Dissertations

The mental health field experiences high levels of stress, resulting in a greater risk of poor professional quality of life, likely exacerbated by the additional stress associated with COVID-19. The present study examined the effect COVID-19 stress had on the professional quality of life of the infant and early childhood mental health (IECMH) workforce and whether coping strategies and self-compassion acted as protective factors. Results indicated that higher COVID-19 stress was associated with higher burnout and secondary traumatic stress (STS) and lower compassion satisfaction (CS). The results also showed that the pathway from COVID-19 stress to burnout was moderated by …

Is It Undervalued? A Qualitative And Quantitative Review Of The Work Values-Job Performance Relationship, Sherif Al-Qallawi

Theses and Dissertations

Researchers have been calling for greater exploration of the relationship between work values and job performance for about five decades (Goodale, 1973; J.-I. C. Hansen & Wiernik, 2017). The current study integrates research on the relationship between work values and job performance over the course of those five decades to better understand this connection. First, a thorough review of work values is presented, including a discussion of their nature, antecedences, construct clarification (how they differ from other individual differences), construct specification (how they differ from other value-based constructs), operationalization, taxonomy, measurement, group differences, stability, and outcomes. This review also includes …

Call The Doctor! A Study Of Parental Medical Nonadherence Within Child Custody Proceedings, Karissa Lynn Cummons

Theses and Dissertations

Medical nonadherence is a common and formidable problem that many pediatric healthcare providers face when treating children with acute and chronic medical conditions because adhering to a physicians’ treatment recommendations is beneficial for successful treatment, disease prevention, and healthy promotion (Dawood et al., 2010). It was estimated that at least one third of patients are unable to complete or adhere to relatively short treatment regimens (Dawood et al., 2010). Reasons for nonadherence to a physicians’ recommendations range from extended duration of treatment, multiple prescribed medications, and periods of symptom remission (Dawood et al., 2010). Despite a parent’s or family’s reason …

Intersections Of Gender And Age: Identification And Attributional Processes On Leadership Effectiveness, Kayla Lynne Bigerton

Theses and Dissertations

As more women enter leadership roles and the ages of leaders becomes more diverse, there is a need for more intersectional research. An intersectional approach was used to assess the impact of leader gender and age on leadership effectiveness through identification and attributional processes. In doing so, different age conceptualizations were also examined. Gender did not have an impact on identification and attributional processes and age had mixed results. Age similarity was not significantly related to leader identification, but perceived leader age had a negative relationship with idiosyncratic fit. Further, social age was examined with different age ranges representing "young”, …

The Effect Of Video Model Dosage And Self-Monitoring On Parent's Use Of Language-Promoting Behavior, Kacie Marie Mcgarry

Theses and Dissertations

Previous research has found a disparity between the language trajectories of children within a high, medium, or low-economic-status family. A relationship is reliably found between the language trajectory of toddlers and success throughout school. This study will evaluate a training package to teach parents to engage in behaviors that promote language and assess the training's short-term effect on the trajectories of children (i.e., growing language) within low-socioeconomic backgrounds. Specifically, experimenters will evaluate the impact of the dosage of video modeling, self-evaluation, and self-monitoring on the acquisition of the targeted skills. Data may suggest that the more accurate the individual is …

Looks And Status Are Still Essential: Testing The Mate Preference Priority Model With The Profile-Based Experimental Paradigm, Jose C. Yong, Yi Wen Tan, Norman P. Li, Andrea L. Meltzer

Research Collection School of Social Sciences

Objective: Although the mate preference priority model (MPPM; Li et al., 2002) has advanced our understanding of mate preferences, tests of the MPPM have relied on methods using text labels and thus lack ecological validity. We address this gap by testing the MPPM using Townsend and colleagues’ (1990a; 1990b; 1993) profile-based experimental paradigm, which utilizes profiles comprising photos of pre-rated models to manipulate physical attractiveness as well as costumes and descriptions to manipulate social status.Method: Using Singaporean samples, we conducted two studies (Study 1 n = 431, Study 2 n = 964) where participants judged the short-term and long-term mating …

Objective: The aim of this study is to examine the relationship between pre-existing headache disorders, such as headache or migraine, and neurocognitive testing obtained before and after college-athletes sustain a concussion. Method: A total of 1129 NCAA Division II college athletes from Florida Tech were included in the present study. Participants were included in this study if they completed baseline and/or post-trauma neuropsychological evaluations that included the Sports Concussion Assessment Tool – Fifth Edition (SCAT-5) and Immediate Post-Concussion Assessment and Cognitive Tool (ImPACT). Athletes’ headache and/or migraine history was self-reported at baseline and indicated their position in headache history or …

Causal Inference In Psychology And Neuroscience: From Association To Causation, Dehua Liang

Computational and Data Sciences (PhD) Dissertations

In psychology and neuroscience, inferring causality in non-experimental studies is almost taboo, because data in these studies, e.g., survey data and resting-state neuroimaging data, are often contaminated by unmeasured confounders. Psychologists and neuroscientists are often cautious about their results, and reluctant to make false claims about causality in non-experimental studies. Therefore, they adopt less stringent statistical analysis techniques that can only infer associational relations. However, the ambiguity about causality in traditional statistical analysis creates much confusion in interpreting analytical results - some studies make implicit causal claims about their results using words such as “impacts”, “lead to” and “affects”. This …
