Exploring Quest And Cultural Humility In Relation To The Spiritual Identities Of Doctoral Clinical Psychology Students At A Christian University, Andrew L. Summerer

Doctor of Psychology (PsyD)

Graduate students receiving doctoral training in clinical psychology from Christian universities often undergo unique changes in their faith identity. Previous research has demonstrated a decline in faith commitment, religious attributions, religious coping, and religious activities during doctoral training (Edwards, 2006; Fisk et al., 2013). While periods of religious disengagement among clinical psychology graduate students seem to be consistent across research studies, some research suggests positive religious transformation as students progress through clinical training and into their professional careers (Hofer, 2004; Pearce, 1996). Cultural humility is an other-oriented stance that is characterized by lifelong learning, cultural self-awareness and reflection, and interpersonal …

Relational Savoring Among Intimate Partners Of Cancer Patients, Adrianna Elyse Holness

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that intimate partners of cancer patients experience similar, if not higher, levels of distress and depression than the patient with regards to the cancer diagnosis. This stress can impact the quality of the relationship and the subsequent care and attention given to cancer patients. As such, identifying factors that can enhance marital relationships during times of illness is key. This project was created in order to assess the efficacy of a brief, portable intervention for improving relational quality among the intimate partners of cancer patients. In this project, we examine the effects of relational savoring, relative to two …

The Effects Of Seizure Modeling And Polyphenols On Behavior In Bang-Sensitive Drosophila, Alphonso A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

Epilepsy is a worldwide public health concern associated with debilitating neurological, cognitive, and psychosocial consequences. Current antiepileptic drugs can have debilitating side effects and new treatments are needed for individuals with pharmaco-resistant seizures like those observed in temporal lobe epilepsy (TLE). Ellagic acid (EA), a polyphenol present in several fruits and nuts, has shown beneficial effects in rodent models of epilepsy and anxiety, possibly mediated through GABAergic pathways. Bang-Sensitive Drosophila mutants model epileptic seizures following mechanical shock and provide a high-throughput alternative to costly rodent studies. The objectives of this study were to: 1) examine the effectiveness of seizure modeling …

The Effect Of Language On Cognition In An Acculturated American Sample Of Healthy Older Adults, K'Dee D. Elsen

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Older adults are not only the fastest growing segment of the population (~841 million worldwide) and continually increasing, but are of special concern due to the numerous age-associated deficits, especially those on cognition. Research indicates that knowing multiple languages may act as a protective factor against the deleterious effects of cognitive aging. Objective: The purpose of the current study is to examine whether multilingualism protects against the effects of cognitive aging on the domains of executive functioning, linguistic processing, attention, memory, and visuospatial functioning. Methods: Participants were 312 healthy older adults (68% female) from the Walnuts and Healthy Aging …

The Effects Of Poverty And Allostatic Load On The Development Of Chronic Disease, Natali Do

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that there is a significant impact of poverty on poor health outcomes. Poverty is associated with limited access to education and healthcare, increased exposure to violence, and chronic stress that contribute to the development of chronic diseases. The poverty and chronic disease relationship is potentially associated with chronically elevated stress biomarkers. The present study investigated the relationship between demographics, poverty (during childhood, young adulthood, and mid/late adulthood), allostatic load—a cumulative measure of system dysregulation—and the Charlson Comorbidity Index, a measure of chronic disease and mortality, using data from the Biopsychosocial and Religion and Health Study (BRHS; Lee et …

Parental Stress, Emotion Regulation, Meta-Emotion, And Changes Following An Mbsr Intervention, Yangmu Xu

Loma Linda University Electronic Theses, Dissertations & Projects

Parents of children with developmental delays (DD) have consistently reported higher rates of parental stress (Dabrowska & Pisula, 2010; Oelofsen & Richardson, 2006). Difficulties with child emotion regulation are often exhibited among children with DD, and the relationship between parental stress and child emotion regulation may be bidirectional. Previous studies have found that underlying thoughts about parent’s own emotions is an important construct that has a direct impact on parental emotional wellbeing and child emotion regulation (Gottman et al., 1996). Furthermore, previous studies suggest that Mindfulness-Based Stress Reduction (MBSR), an empirically supported stress-reduction intervention, is efficacious in reducing parenting stress …

Role Of Cultural And Psychological Factors Influencing Diabetes Treatment Adherence, Sonika Kravann Ung

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic diseases are the leading causes of disability worldwide although health complications can be prevented with lifestyle change (CDC, 2013). Type 2 diabetes is a growing global epidemic, and its prevalence is predicted to increase from 6.4% (285 million adults) in 2010 to 7.7% (439 million adults) by 2030 (Shaw, Sicree, & Zimmet, 2010). Given the reality of cultural diversity in contemporary society, the aim of this study was to address the need for research that integrates both cultural and psychological factors with behaviors central to diabetes control among culturally diverse populations (Betancourt & López, 1993; Betancourt, Flynn, Riggs, & …

A Parent Education Curriculum For Decreasing Stress In Families Raising A Child With An Autism Spectrum Disorder, Hannah L. Wohlk

Electronic Theses, Projects, and Dissertations

Research has consistently shown that parents raising a child with autism spectrum disorders, or ASDs, have higher levels of stress than parents of typically-developing children or children with other disabilities. These parents’ higher levels of stress are attributed to a number of different factors, including early atypical development, getting the diagnosis, lack of awareness of resources, lack of support from their communities, unmet resource and schooling needs for their ASD child, financial strain, strain on the couple relationship, managing maladaptive behaviors, regulatory problems of the ASD child may experience, communication problems between ASD child and parent, parents’ perception of their …

Food Insecurity And Eating Disorder Pathology, Carolyn Becker, Keesha M. Middlemass, Brigitte Taylor, Clara Johnson, Francesca Gomez

Psychology Faculty Research

Objective: The primary aim of this study was to investigate eating disorder (ED) pathology in those living with food insecurity. A secondary aim was to investigate whether any-reason dietary restraint, weight self-stigma, and worry increased as level of food insecurity increased.

Method: Participants (N = 503) seeking food from food pantries completed questionnaires assessing level of food insecurity, demographics, ED pathology, dietary restraint, weight self-stigma, and worry.

Results: Consistent with hypotheses, participants with the highest level of food insecurity (i.e., adults who reported having hungry children in their household) also endorsed significantly higher levels of binge eating, overall ED …

Smoking, Adhd, And Problematic Video Game Use: A Structural Modeling Approach, Hyo Jin Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Problematic video game use (PVGU), or addiction-like use of video games, is associated with negative physical and mental health problems as well as problems in social and occupational functioning. Possible contributors to PVGU include frequency of play, cigarette smoking, and ADHD. The aim of the current study was to explore the relationships among PVGU, cigarette smoking, ADHD, and frequency of play simultaneously using a structural modeling approach. Secondary data analysis was conducted on 2,801 video game users (Mage = 22.43 years, SDage = 4.7; 93% male) who completed an online survey comprising measures of PVGU, ADHD symptomatology, smoking behavior, and …

The Role Of Temporal Distraction On Short-Term Memory And Delayed Recognition, Susanna Luu

Loma Linda University Electronic Theses, Dissertations & Projects

Memory is a complex process that requires the translation of information from an external sensory experience into an internal representation. Once information has been translated into memory, there is little agreement regarding the cognitive structure of memory storage and maintenance. Baddeley (1966) developed a model based on a multi-storage structure which suggested that as information entered through the sensory system, it was relayed by a cognitive control center and placed into storage units based on information type (i.e. auditory, visual, etc.). Baddeley’s (1966) multi-store memory model hypothesized that content translated into memory by two phases: short-term and long-term memory. More …

Book Reviews: Recent Books On Pornography: From Discussions Of Harm To Normalization, Robert Brannon

Dignity: A Journal of Analysis of Exploitation and Violence

Nine books addressing the specific harms linked to adults’ viewing of heterosexual pornography are examined. All were published since 2010, and range from some that are opposed to all pornography, to others that approve of pornography. The books differ considerably in scope, quality, and scientific rigor. Several include discussions of the feminist anti-pornography movement, in the U.S. and worldwide, from 1975 to the present. These accounts range from criticism of the anti-pornography movement to praise and appreciation. This collection of books provides a useful view of the remarkable diversity of thought about all issues connected with pornography’s effects on adult …

Sex Trafficking Survivor, Pro-Life Advocate, Darlene Pawlik

Dignity: A Journal of Analysis of Exploitation and Violence

I was conceived by rape. I was mentally, physically and sexually abused as a child. I endured four years of juvenile sex trafficking. These experiences shaped my views on abortion and pro-life issues. Drawing from my personal experience and the experiences of others, as well as referring to empirical evidence, I set forth the position that children conceived through sexual violence are no less deserving of protection than those conceived in loving relationships. Preserving the health and dignity of sexual abuse survivors is important and supportive help is needed.

Sexual Conflict In Mating Strategies, Norman P. Li, Jin Chuan Yong

Research Collection School of Social Sciences

Why do men and women come into conflict over mating and sex? This chapter examines the adaptive reasons, which trace back to key differences in minimum obligatory parental investment (Trivers 1972). Reflecting these differences, men tend to be relatively eager for casual sex, whereas women are relatively more cautious, requiring their sexual partners to be of higher quality or committed for a longer duration. As each side strives for its own reproductive interests, the other side’s strategy is often interfered with, resulting in conflict.

Tackling The Health Gap: The Role Of Psychosocial Processes, Nancy E. Adler, Jacinth J. X. Tan

Research Collection School of Social Sciences

In The Health Gap, Michael Marmot describes how, starting even before birth, social conditions set individuals on trajectories that eventuate in inequities in health and longevity. In addition to race and ethnicity, socioeconomic status linked to income and education plays a major role in determining health trajectories. The effects emerge not only at the very bottom of the socioeconomic spectrum, but across the whole range.1 The fact that health effects persist at levels where resources are more than adequate to fulfill material needs suggests that the health gap is not due only to material privation associated with poverty, but also …

Parental Influence On Second Generation Chinese-American Youth’S Career Choice And Development, Yingli Huang

Dissertations, Theses, and Capstone Projects

A large body of literature supports the claim that the role of parents in shaping Asian-American youth's career development is significant (Leong & Serafica, 1995; Leong & Hardin, 2002; Yuan, 2012; Sandhu, 2017; Qin, 2011). When considering the family impact on Asian-Americans’ vocational choices, researchers should examine the phenomena through culturally specific lens so that variables that are more cultural relevant are captured. This is a pilot study with the goal to provide a preliminary understanding of the ways in which first-generation Chinese immigrant parents influence the choice and development of a career to their second-generation young adult children. In …

Aberrant Salience And Probabilistic Reasoning In Distressing Attenuated Positive Psychotic Symptoms: An Examination Of A Two Factor Model, Huw Green

Dissertations, Theses, and Capstone Projects

Theoretical psychological models of positive psychotic symptoms have increasingly emphasized the interaction of multiple cognitive factors. Research into delusions in particular has focused on the interaction of two factors; a perceptual anomaly that gives rise to a need for explanation, and a bias toward premature acceptance of a hypothesis. Recently this two factor approach has been applied to positive psychotic symptoms more broadly. Two candidate factors have received extensive theoretical and empirical interest. The aberrant salience hypothesis posits that salience regulation, mediated by dopamine, goes awry in psychosis, giving rise to a generalized sense of undue significance that is applied …

The Long-Term Consequences Of Child Abuse And Neglect In Men, Robert A. Beattey Jr.

Dissertations, Theses, and Capstone Projects

Research indicates that the annual incidence of child maltreatment is around 10% and that more than one-quarter of children have, at least indirectly, experienced some form of violence. Prospective studies find that in high-income countries, like the United States, there are moderate correlations between childhood maltreatment and low educational achievement, low skilled employment, depression, suicide attempts, and alcohol problems, as well as strong correlations with obesity, behavior problems in childhood and adolescence, and criminal behavior. Despite the high costs of child abuse and neglect—both direct and indirect—and decades of research and public health, justice, and social service investment in prevention …

The Nucleus Accumbens Core Dopamine D1 And Glutamate Ampa/Nmda Receptors Play A Transient Role In The Performance Of Pavlovian Approach Behavior, Veronica Dobrovitsky

Dissertations, Theses, and Capstone Projects

The role of the nucleus accumbens core (NAc core) continues to be redefined with newly acquired data on neurochemical mechanisms mediating the learning and performance of behavior. Previous empirical data showed that dopamine transmission at the D1 receptor (D1R) plays a transient role in the expression of learned Pavlovian approach behavior. Here we show that, prior to overtraining, dopamine activity at D1Rs specifically within the NAc core is critical for the performance of approach behavior elicited by the recently-acquired reward-paired cue. Blockade of D1Rs in the NAc core, but not the dorsomedial striatum or NAc shell, disrupted approach responses during …

The Contributions Of Child And Romantic Attachment To Sleep Quality, Karen Estefane

Dissertations, Theses, and Capstone Projects

Little is known about the relation between attachment and sleep, although both develop around the first year of life and mutually influence each other. Furthermore, attachment styles and dimensions have been associated with sleep difficulties in both childhood and adulthood. However, these findings have not been consistent, especially among dismissing individuals. In addition, the specific contributions of both child and romantic attachment to sleep quality have not been investigated thus far. This cross-sectional study aims to examine the ways child and romantic attachment are associated with sleep quality. A sample of 671 heterosexual residents of the United States, aged 18 …

Psychoanalysis And Modernity: A Failure To Find Relief From Existential Terror, Erin Liat Claridge

Dissertations, Theses, and Capstone Projects

This project considers the ways in which culture—the symbols and institutions that guide behavior and provide meaning to the individuals living within a community—serves a defensive function against conscious awareness of existential terror. The term existential terror refers to the cognitive and emotional experience of recognizing the inevitability of death, which is often accompanied by feelings of angst, isolation from others, and awareness of meaninglessness. In this dissertation, I will argue that the broad shift from traditional culture based on Judeo-Christian religious beliefs and communal forms of social life to modernity represents a slow but destabilizing deterioration of the defensive …

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …

Behavioral Responses To Pulses Of Light In The Longfin Inshore Squid, Doryteuthis Pealeii (Lesueur, 1821), Stavros P. Hadjisolomou

Dissertations, Theses, and Capstone Projects

The coleoid cephalopods (octopus, squid, and cuttlefish) are masters of rapid, adaptive camouflage. Unlike the slower hormonal chromatophore control of flatfish and chameleons, coleoid mollusks can change body patterns in milliseconds. Visual camouflage in coleoids is driven by a sensorimotor system consisting of visual input of their surroundings, a sophisticated central nervous system for information processing, and a neuromuscular control for body patterning. Motor neurons selectively activate millions of muscles, alternately expanding and reducing the pigmented chromatophores to generate visible brown, red, orange and yellow patterns on the skin. Below the chromatophore-layered skin are two types of reflecting cells, iridophores …

Understanding The Role Of The Ventrolateral Prefrontal Cortex In Emotional Memory Using Transcranial Direct Current Stimulation And Transcranial Magnetic Stimulation, R. Rachel Weintraub-Brevda

Dissertations, Theses, and Capstone Projects

Emotional stimuli can have both beneficial and detrimental effects on memory, such that emotional stimuli can be distracting from current neutral working memory goals, while also leading to enhanced episodic memory for the distracting emotional stimuli. Recent evidence suggests that the ventrolateral prefrontal cortex (VLPFC) has multiple roles in the enhancing effects of emotion on memory through top-down/controlled processes, including 1) coping with negative distraction and 2) elaborative encoding of negative information. Additionally, previous research has alluded to hemispheric differences in the VLPFC (Chapter 1). However, previous research has been correlational, with no strong laterality tests of the VLPFC. Two …

Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …

Ecologies Of Embodied Minds Embedded: Radical Romantic Perspectives On Architectures Of Technology, Sharmaine Browne

Dissertations, Theses, and Capstone Projects

This dissertation explores Romantic responses to the role of architectural technologies in the development of material being, consciousness, and culture by applying a critical approach in which I combine radical embodied cognitive theory, ecocritical perspectives, and a phenomenological lens to select Romantic texts written from 1789 to 1884 in response to industrial modernity. While scholarship has thoroughly explored technology as a cultural force which inevitably shapes consciousness, I propose that a slight shift of emphasis from technology’s external influence to the material internalization of its influence allows for new perspectives—particularly in light of recent proposals in cognitive philosophy which assert …

Past Peer Victimization Experiences And Current Psychological Well-Being And Ethnic Identity Among South Asian College Students, Rejitha Nair

Dissertations, Theses, and Capstone Projects

Very little is known about the peer victimization experiences of South Asian immigrant students and the factors involved in these experiences. The present study retrospectively investigated the peer victimization experiences of South Asian immigrant students in high school, the perceived reasons for victimization, and how these experiences relate to their psychological well-being and ethnic identity as college students. Two hundred and twenty college students, who were first or second generation immigrants from South Asia (e.g., India, Pakistan, Afghanistan, Bangladesh, Sri Lanka, and Nepal) and attended high school in the United States, participated in the study.

Overall, the results revealed that …

Clinical Uses For Psychedelic Drugs, Matthew Clarkson

Missouri S&T’s Peer to Peer

Throughout the last forty years, psychedelic drugs have been illegal in the United States. Stigmatized due to the potential for abuse, the use of these drugs has been relegated to simple criminal activity and research stagnated for those 40 years. Slowly, research has begun to pick up as the restrictions begin to lift incrementally. However, the current restrictions are intense, further limiting the amount of research conducted that can reveal the medical benefits of these drugs. Through multiple studies, both open-label and double-blinded to show both feasibility and efficacy, as well as the biological impact of the drugs, significant anxiolytic, …

Altered Sensitivity To Social Gaze In The Fmr1 Premutation And Pragmatic Language Competence, Jessica Klusek, Joseph Schmidt, Amanda J. Fairchild, Ann Porter, Jane E. Roberts

Faculty Publications

Background: The FMR1 premutation affects 1:291 women and is associated with a range of cognitive, affective, and physical health complications, including deficits in pragmatic language (i.e., social language). This study investigated attention to eye gaze as a fundamental social-cognitive skill that may be impaired in the FMR1 premutation and could underlie pragmatic deficits. Given the high prevalence of the FMR1 premutation, efforts to define its phenotype and mechanistic underpinnings have significant public health implications. Methods: Thirty-five women with the FMR1 premutation and 20 control women completed an eye-tracking paradigm that recorded time spent dwelling within the eye region in response …

Psychological Well-Being’S Link With Cardiovascular Health In Older Adults, Julia K. Boehm, Jackie Soo, Ying Chen, Emily S. Zevon, Rosalba Hernandez, Donald Lloyd-Jones, Laura D. Kubzansky

Psychology Faculty Articles and Research

Introduction

Favorable cardiovascular health (FCH) is associated with healthy longevity and reduced cardiovascular mortality risk. However, limited work has investigated the distribution of FCH in older age or considered the antecedents of FCH. Based on prior work linking psychological well-being with cardiovascular endpoints, higher psychological well-being was hypothesized to be associated with increased likelihood of maintaining FCH over time.

Methods

Data were from the English Longitudinal Study of Ageing. The first study wave (2002–2003) included men and women aged ≥50 years. The analytic sample (N=4,925) was restricted to individuals without baseline cardiovascular disease and with clinical data from three follow-ups …
