Toward A Biopsychosocial Model Of Obesiy: Can Psychological Well-Being Be The Bridge To Integration?, Alexia Holovatyk

Theses and Dissertations

The complications associated with obesity are some of the most pressing health concerns facing the United States. At present, cardiovascular disease, stroke, and certain types of cancer are some of the leading causes of death, and researchers have cited obesity as one related factor (NIH, 2000). The topic of obesity has typically been approached through two seemingly contradictory lenses: The biomedical model that views obesity as a disease risk factor (e.g. Huxley, Mendis, Zheleznyakov, Reddy, & Chan, 2010) and the psychosocial model that considers the stigma associated with obesity to be more harmful than weight itself (e.g., Hatzenbuehler, Keyes, & …

A Novel Cognitive Stress Test For The Detection Of Early Alzheimer’S Disease In African Americans, Kimberly Capp

Theses and Dissertations

The U.S. population is currently undergoing a major demographic transition, with increasing racial and ethnic diversity of the older adult population. As the growing population of older adults advances in age, memory complaints are projected to increase in prevalence particularly among African Americans and present a challenge to clinicians who must differentiate between normal aging and progressive neurocognitive conditions (Celsis, 2000; Sherwin, 2000). As targeted therapeutic interventions and emerging therapies for AD are much more likely to be effective in the earlier stages of the disease (Loewenstein, Curiel, Duara & Buschke, 2017), early assessment and detection of AD, especially in …

Breaking Away: The Role Of Homeostatic Drive In Perpetuating Depression, Jonathan Tory Toole

Theses and Dissertations

The brain can be considered a complicated system of feedback mechanisms that maintain physiological homeostasis. Through psychological activity, neurochemicals act as homeostatic regulators. This study proposes that these components are part of a regulatory system that is capable of supporting multiple homeostatic regimes that, in turn, give rise to self-sustaining psychological behaviors. This project hypothesizes that such alternate regulatory programs may play a role in perpetuating psychological dysfunction. Interactions within and between components of the neurotransmitter network are represented as a set of discrete logic circuits. Neurotransmitter levels are linked to psychological constructs such as depression based on current literature. …

Authentic Perspectives On Autistic Resilience: Implications For Schools And Society, Andrew Nelson

Theses, Dissertations and Capstones

This study explored resilience factors as identified by autistic adults with authentic lived experience. Historically, Autism Spectrum Disorder (ASD) has been diagnosed using deficit models and criteria designed by outsiders with little input from the autism community. While risk of adversity is often high for those with ASD, scant research exists looking at the strengths, adaptive skills, and environmental factors contributing to the resilience of people with ASD. Autistic adults were interviewed (N = 10) to assess which internal and external risks and protections participants deemed important to their resilience. Responses were coded, analyzed, and compared to existing resilience data …

Comparative Examination Of The Empatica E4 To Record Heart Rate Variability Metrics, Andres Rosero

Honors Undergraduate Theses

The increased accessibility of cyber technology has resulted in advancements in international communications and information sharing never seen in human history. With this new age of digital software comes the proliferation of illegal online activity and cyber terrorism. Repercussions of cyber-attacks have ranged from identity theft to leaks of classified state secrets. To combat this threat, the Department of Defense (DoD) established the Cyber Mission Force (CMF) to head operations in the interests of protecting against cyber-attacks. One of the CMF’s initial projects involves the creation of a Performance Assessment Suite (PAS), a training program designed to improve the training …

Stress Perception And Measurement In Missionary Populations, Laurie A. Tone, Fernando Garzon, John C. Thomas, Brigitte Ritchey, Mike Malek-Ahmadi

Faculty Publications and Presentations

Christian missionaries experience numerous stressors across multiple domains. To understand their unique experiences, a targeted assessment is required. There is no known psychometrically tested measure that captures the nuances of stress for this population. To that end, as part of a larger study, the quantitative CHOPS Stress Inventory, a new tool for measuring missionary stress was developed and showed good initial psychometric qualities when compared to an established stress measure. Furthermore, the Analysis of covariance (ANCOVA) of survey findings on 267 cross-cultural evangelical missionaries noted that both age and sex demonstrated significant effects on perceived stress scores. Implications for missionary …

Prefrontal Cortical Activation In Naturalistic Walking, Aimee L. Klaschus

Honors Undergraduate Theses

Tasks and environments that demand greater attention resources result in greater activation of the prefrontal cortex (PFC). To explore this effect in a naturalistic setting, we used functional near-infrared spectroscopy (fNIRS) to record the PFC activation of six undergraduate participants while they walked in a busy environment (attention-demanding) and quiet environment (non-attention-demanding). Walking speed was recorded as a behavioral correlate. Results indicated that there was no statistically significant difference in walking speed or cortical activity between busy and quiet conditions, though the trend was in favor of the hypotheses. This is likely because crowd density within each condition was not …

Precarious Womanhood: Maternal Instinct’S Role In Gender-Related Anxiety, Chelsey Kanipe

Master's Theses and Doctoral Dissertations

The phenomenon of “precarious manhood” suggests that when a man perceives a threat to his masculinity, he will respond with anxiety and will subsequently increase his displays of traditional masculinity. The main purpose of this study is to address a parallel phenomenon in women (i.e., “precarious womanhood”), the existence of which previous authors have dismissed. Participants were randomly assigned to receive either high scores, low scores, or no scores following a supposed maternal instinct questionnaire. Then, their subsequent mood and gender identity endorsement were measured via self-report. It was hypothesized that, compared to participants who received either high or no …

Does Inhibitory Control And Emotion Regulation Alter The Degree To Which Aggressogenic Thought Is Expressed?, Jessica Lindsey Held

Theses and Dissertations

The effects of emotion dysregulation and inhibitory control on aggressogenic thought-behavior associations were investigated among 362 fifth- and sixth-grade boys (n = 195) and girls (n = 167) on Long Island, New York. Other-reported anger dysregulation and inhibitory control significantly qualified the relationship between all three cognitions (hostile attributions of intent, revenge goals in both ambiguous and unambiguous situations, and self-efficacy) and aggression. However, our predicted pattern for these 3-way interaction was supported only when the cognition involved self-efficacy—self-efficacy for aggression was most strongly associated with aggressive behavior under high levels of anger dysregulation and low levels of inhibitory control. …

Identifying Mcmi-Iv Personality Disorder Subgroups Using Exploratory Factor Analysis And Latent Class Analysis, Amanda Fisher

Theses and Dissertations

Patients diagnosed with personality disorders (PDs) have higher morbidity and mortality rates than those without PDs. The DSM-5 PD diagnoses and the cluster system lack a theoretical and empirical basis, which hinders the development of knowledge about PDs and interventions for PDs. This present study attempts to add to this literature by forming PD groups using a combination of exploratory factor analysis (EFA) and latent class analysis (LCA) based on PD scores from the Millon Clinical Multiaxial Inventory-IV (MCMI-IV), a method recommended by Gorman and Primavera (1983). Participants were 251 English speaking males and females ages 18 to 75 seeking …

Examining The Relationship Between Alzheimer’S Disease, Depression, And Social Support, Marko Lamela

Theses and Dissertations

This study examined the relationship between Alzheimer’s Disease and depression to determine whether a correlation existed and whether depression led to greater outcomes of Alzheimer’s Disease. Depression-Alzheimer’s relations have been mixed in previous research. Data from an existing data set of visitors to the Alzheimer’s Disease Centers with three or more visits (N= 19, 652) was used to test correlations between depression and Alzheimer’s, later odds of developing Alzheimer’s, and possible moderating effects of social support. A positive correlation was found between depression and Alzheimer’s Disease. Patients with depression were found to be more likely to have Alzheimer’s. There was …

What Happens Next? A Grounded Theory Exploration Of The Psychological Impact Of Leaving The Gang, Alana C. Liskov

Electronic Theses and Dissertations

Very little research exists regarding the psychological impacts of gang membership and the mental health needs of gang members. Of the few studies that have been conducted, gang members were found to have increased rates of post-traumatic stress disorder (1.77 odds), current substance abuse (2.58 odds), oppositional defiant disorder, (1.24 odds) and conduct disorder (4.05 odds) (Harris, Elkins, Butler, Shelton, Robles, Kwok, Simpson, Young, Mayhew, Brown, & Sargent, 2013). Violent ruminative thinking, violent victimization and fear of further victimization were also significantly higher in gang members and believed to account for high levels of psychosis and anxiety disorder in gang …

The Effects Of Adverse Childhood Experiences On Behavioral Outcomes, Jennifer Thomas

Electronic Theses and Dissertations

This study intends to explore the intersection of two vulnerable populations, early childhood development and risks associated with exposure to adverse childhood experiences (ACEs). This study examines how age plays a role in the long-term relationship between ACEs and internal and external behaviors. This study seeks to answer the question of: How does age influence the relationship between number of ACEs and internal and external behaviors? The participants in this study include those aged 0 – 16 from the National Survey of Child and adolescent Well-Being (NSCAW) dataset. The NSCAW study consists of five waves of data where Wave I …

A Phenomenological Exploration Of Korean Adoptees’ Multiple Minority Identities, Jared Utley

Electronic Theses and Dissertations

Since the end of the Korean War, Korean children have been placed for international adoption due to their marginalized status in South Korea. In the United States, Korean children have predominantly been adopted to White families through transracial adoption (Bergquist, 2003; Lee, 2003). Transracial adoption describes the process of children being placed in a home where there are racial differences with one or both adoptive parents. Through international transracial adoption, Korean adoptees may undergo events that impact the salience and development of multiple minority identities, including: racial, ethnic, cultural, and as an adoptee. These experiences may be shaped by interactions …

Black Minds Matter: A Phenomenological Inquiry Examining The Prevalence Of Racial Trauma Among Black Doctoral Students, Jazmyne Markeeva Peters

Electronic Theses and Dissertations

Systemic and institutionalized racism is endemic to life in the United States and contributes to the daily marginalization of Black people. While the negative psychological and physiological effects of racism have been well-documented, the notion that racism can be experienced as a trauma is a newer theory. Racial trauma has been understudied and underappreciated, though it is a theory that clinicians should incorporate when working with Black clients and other clients of color. Exploring the ways in which Black doctoral students attending a predominantly White institution (PWI) have experienced racism is an essential contribution to the existing racial trauma literature. …

Caballerismo In Latinx Men In Higher Education, Victor Carrasco

Electronic Theses and Dissertations

Latinx men continue to be marginalized in higher education, and more research is needed to understand how to retain them using anti-deficit frameworks (Cook et al., 2012). Studies have investigated caballerismo as a protective factor for LatinX men. Caballerismo is defined by egalitarian beliefs, affiliation, positive family relationships, and empathy (Arciniega et al., 2008; Neff, 2001). Despite its promise as an anti-deficit framework, little is known about how caballerismo informs Latino students’ experiences in higher education. Therefore, this study addresses the following research questions: a) How does caballerismo manifest in Latinx men in higher education, b) how does caballerismo intersect …

Xylo-Bot: A Therapeutic Robot-Based Music Platform For Children With Autism, Huanghao Feng

Electronic Theses and Dissertations

Children with Autism Spectrum Disorder (ASD) experience deficits in verbal and nonverbal communication skills, including motor control, emotional facial expressions, and eye gaze / joint attention. This Ph.D. dissertation focuses on studying the feasibility and effectiveness of using a social robot, called NAO, and a toy music instrument, xylophone, at modeling and improving the social responses and behaviors of children with ASD. In our investigation, we designed an autonomous social interactive music teaching system to fulfill this mission.

A novel modular robot-music teaching system consisting of three modules is presented. Module 1 provides an autonomous self-awareness positioning system for the …

Social Learning In Solitary Juvenile Sharks, Catarina Vila Pouca, Dennis Heinrich, Charlie Huveneers, Culum Brown

Social Behavior Collection

Social learning can be a shortcut for acquiring locally adaptive information. Animals that live in social groups have better access to social information, but gregarious and nonsocial species are also frequently exposed to social cues. Thus, social learning might simply reflect an animal's general ability to learn rather than an adaptation to social living. Here, we investigated social learning and the effect of frequency of social exposure in nonsocial, juvenile Port Jackson sharks, Heterodontus portusjacksoni. We compared (1) Individual Learners, (2) Sham-Observers, paired with a naïve shark, and (3) Observers, paired with a trained demonstrator, in a novel foraging task. …

Loneliness And Sleep: A Systematic Review And Meta-Analysis, Sarah C. Griffin, Allison B. Williams, Scott G. Ravyts, Samantha N. Mladen, Bruce D. Rybarczyk

Psychology Publications

Despite the mounting evidence linking loneliness with health, the mechanisms underlying this relationship remain obscure. This systematic review and meta-analysis on the association between loneliness and one potential mechanism—sleep—identified 27 relevant articles. Loneliness correlated with self-reported sleep disturbance (r = .28, 95% confidence interval (.24, .33)) but not duration, across a diverse set of samples and measures. There was no evidence supporting age or gender as moderators or suggesting publication bias. The longitudinal relationship between loneliness and sleep remains unclear. Loneliness is related to sleep disturbance, but research is necessary to determine directionality, examine the influence of other factors, …

Where For What: A Meta-Analysis For The Category-Specific Activations For Living/Nonliving Concepts In The Past Two Decades, Kimberly D. Derderian, Xiaojue Zhou, Lang Chen

Psychology

The cortical organization of the semantic network has been studied extensively in neuropsychological and neuroimaging studies. Recent theories have heavily relied on the observation of category-specific activations, i.e., the preferential activations in brain regions for specific semantic categories. With decades of research, a full understanding of the organization has not yet been reached, since little is known about the factors that contribute to the variances in observed activation patterns across numerous neuroimaging studies. In this study, we first reviewed 97 published papers that reported category-specific activations for living or nonliving concepts in the past two decades. Then, using the Activation …

Model Of Autonomous-Related Singles Counseling In Collectivistic Cultures: The Turkey Model, Kâmile Bahar Aydın

Papers from the International Association for Cross-Cultural Psychology Conferences

In this paper the Model of Autonomous-Related Singles Counseling (MARSC) is introduced. MARSC is based on Kağıtçıbaşı's (1996) Autonomous-Related Self Model (ARSM) and on Aydın’s (2017, 2019) Singles Counseling Theory which have been developed in Turkey, a country that scores high on collectivism (Hofstede, 1980). In both models, the basic psychological needs of autonomy and relatedness are the key concepts. ARSM is a supplementary synthesis model that integrates two constructs assumed to be conflicting, and it is based on cross-cultural diversity: autonomy and relatedness. ARSM is prevalent in collectivistic cultures. Research conducted on diverse national and ethnic groups in Brazil, …

On Positioning, Deafness, And Educational Research: An Autoethnography On Deafness And Qualitative Research, Sara K. Parrish

2020 Faculty Bibliography

Combining autoethnography and disability studies in education, this article is an autoethnographic study of the different ways the author was positioned as abled and disabled by her institution’s review board when reviewing her qualitative research proposal. The author talks back to the prevailing understandings of disability and conceptions of research that emerged as she interacted with the review board. Through the article, the author problematizes the ableism that surfaced and seeks to redefine what it means to be a qualitative researcher in spite of and because of her deafness. She ends by arguing for a more inclusive understanding of what …

Youth With Juvenile Justice Contact: Special Considerations In Measurement, Anne Elizabeth Biehl

Electronic Theses and Dissertations

Students who have contact with the juvenile justice system are a particularly vulnerable and unique school-aged population. The risk factors that plague the likelihood of justice-involvement are numerous and inter-connected. Early experiences of trauma and adversity, limited familial and financial capital, and challenges with mental health all contribute to increased likelihood of youth contact with juvenile justice systems. Despite said risk factors effects on young people overall, youth of color are particularly susceptible to become justice-involved. School and community discipline statistics are grossly, racially disproportionate.

Pathways from schools to the justice system have been widely investigate in the literature. There …

Pivotal Perceptions: A Phenomenological Exploration Of Trauma-Informed Practices In An Urban School, Marni Choice-Hermosillo

Electronic Theses and Dissertations

This phenomenological study sought to examine the experiences of teachers in an urban K-8 school after a system-wide whole school implementation of trauma-informed practices. The practices teachers implemented in their classrooms that aligned with their personal perceptions of trauma-informed practices and its efficacy were explored. Additionally, the personal and professional barriers to implementation were also investigated. Identified practical strategies at both the elementary and middle school levels included establishing and maintaining relational trust and classroom community, actively teaching emotional regulation skills, and teaching and reinforcing rituals, routines and expectations throughout the school year. Lack of confidence and previous personal assumptions …

Infant Temperament And Cardiac Physiology As Predictors Of Infant Locomotion, Mequeil Howard

Mahurin Honors College Capstone Experience/Thesis Projects

Infant locomotion is a major milestone that occurs during the first year of an infant’s life, and the onset of crawling is associated with various developmental changes. Previous work has focused on changes in infant temperament, specifically anger, during the onset of crawling. Other work has focused on changes in infant cardiac physiology in association with temperament development. Little research has examined both temperament and cardiac physiology (e.g., respiratory sinus arrythmia, RSA) as predictors of infant locomotion. Examining both factors in the same study could further explain variability in infant motor development. The current longitudinal study examined infant temperament (anger, …

A Qualitative Study Of Non-Relational Foster Families Experiences Navigating The Education System, Emma Grace Topf

Electronic Theses and Dissertations

This qualitative study used a phenomenological approach to capture the lived experience of non-relational foster families navigating the Colorado public education system. While most research on children in foster care looks at all sub-populations of foster care combined, this is the first known study to focus solely on non-relational foster families navigating the education system. I explored non-relational foster parents experience navigating the education system for the school-age children in their care through a semi-structured two-interview approach. Four levels of data analysis were completed (descriptive coding, emergent coding of themes, a priori coding of research questions, and a priori coding …

Ptsd And Immunological Correlations Of Attention And Working Memory In Gulf War Illness, Mary Jeffrey

Theses and Dissertations

Gulf War Illness (GWI) impacts 25 to 32 percent of those deployed in the 1991 Gulf War (White et al., 2016) and includes symptoms related to fatigue and mood/neurological disturbances. Therefore, it is difficult to ascertain the influence of trauma exposure and chemical exposure when investigating neuropsychological symptoms. This cross-sectional study utilized a group of veterans with and without GWI (n=61) to investigate: 1) the unique impact that GWI has on a survey measure of attention and memory or the Paced Auditory Serial Addition Test (PASAT). We also investigated how PTSD symptoms, followed by fatigue levels, improved the GWI model …

Working For A Living: A Terror Management Theory Approach To Finding Meaning In Vocation, Julian T. Frazier

Electronic Theses and Dissertations

Many individuals spend approximately a third of their lives either working, receiving training or education for work or otherwise engaged in their career. While the current literature attempts to discern the many roles that work can play in our lives, it only scantly explore the existential nature of work in relation to death and mortality. Terror Management Theory provides a framework explaining how increases in awareness of our mortality influences our behavior and beliefs. By studying work constructs from the lens of Terror Management Theory, we seek to gain insight on the potential role that work plays in bolstering psychological …

The Casc Framework: An Assessment Model For Students With Intellectual And Developmental Disabilities, Laurel A. Snider

Electronic Theses and Dissertations

School psychologists pay a critical role in providing assessment and intervention services within the realm of special education. Within this role, they are highly likely to interact with students with intellectual and developmental disabilities (IDD). Students with IDD are characterized by significantly lower than average cognitive and daily living skills that may be comorbid with difficulties with communication, social skills, or other domains. With these differences in mind, dominant assessment practices have been criticized as lacking social and empirical validity when applied to this population. Although students with IDD frequently undergo evaluations, they continue to face significantly poorer post-school outcomes …
