Sex In The Brain: The Relationship Between Event Related Potentials And Subjective Sexual Arousal, Taylor Lynn Oliver

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research investigating the relationship between subjective sexual arousal and physiological arousal has focused primarily on measures of genital arousal and has yielded only modest concordance rates between genital and subjective sexual arousal in men, and low concordance rates in women. One of the nagging confounds in the literature, however, has been the fact that different assessment methods are necessitated by men and women's differing genital physiology (i.e., vaginal photoplethysmography in women and penile plethysmography in men). This study sought to investigate the relationship between subjective sexual arousal and a different type of physical arousal (brain activation) that could be measured …

Faith And Homosexuality: Grace, Religious Problem-Solving Styles And The Internalized Homophobia Of Homosexuals, Maria R. Matty

Honors Theses

The current research examines the grace-orientation and problem-solving styles of gay and lesbian people of faith relative to their relationship with God and the extent, if any, of their internalized homonegativity. This issue was investigated using psychological measures involving a) the style of religious problem-solving, b) internalized homonegativity, c) feelings of shame and guilt and d) personal experiences of grace. Statistical analyses found that having less homonegativity toward oneself and the disclosure of homosexuality is associated with higher levels of experienced grace and lower feelings of shame and guilt. Collaborative and deferring religious problem-solving styles correlated positively with both experienced …

A Guide For The Psychosocial Treatment Of Infertility, Linnea Esselstrom

Loma Linda University Electronic Theses, Dissertations & Projects

Infertility is a growing area of the medical field and a common problem experienced by couples and individuals during their lifetime. Stress is known to decrease fertility in men and women, and may also impact fertility treatment outcomes. Psychological burden is associated with treatment discontinuation, due to the physical and emotional stress associated with the personal, social, and medical aspects of infertility. A review of the research literature was conducted to examine the impact of infertility on social and psychological domains, as well as identify the relationship between stress, distress, and infertility, to inform how mental health services may improve …

Chronic, Lethal Versus Acute, Non-Lethal Threats: A Look Inside The Memories Of Cancer Patients At The Time Of Their Diagnosis, Angeline M. Modesti

Undergraduate Honors Thesis Collection

Consequentiality, affect, and rehearsal are also important components that help contribute to the recall of autobiographical memories. Traditionally, these features have been assessed in public dramatic events in the past such as the Challenger explosion and the 9/11 terrorist attack. In opposition to these traditionally studied events, the present study examined the effects of these features on five different private events. An analysis of these different experiences was assessed to determine the role of consequentiality, affect, and rehearsal play on memory recall. These three components were assessed in five different events during different points of the lifetime. Adults diagnosed with …

An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins

Honors Scholar Theses

Patients with depression, schizophrenia, and other related disorders often show effort-related motivational symptoms such as anergia, psychomotor slowing, lassitude, and fatigue. Several studies have indicated that dopamine (DA) within the nucleus accumbens (NAc) is involved in the regulation of effort-related behavior. Interference with NAc DA alters response allocation in effort related choice procedures, biasing animals towards the alterative that can be obtained with minimal effort. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) shifts behavior in rats responding on the FR5/chow choice procedure causing a decrease in lever pressing and a compensatory increase …

Olfactory Identification, Detection Thresholds, And Sensitivity In Kidney Disease Patients, Joseph Wesley Jones

Masters Theses and Doctoral Dissertations

While there is evidence for a decline in olfactory identification scores for patients with Kidney Disease, there are contradictory results for detection thresholds. Some results indicate higher thresholds while others found similar thresholds or elevated thresholds for one odorant, but not others. The current study evaluated the olfactory abilities with participants diagnosed with Kidney Disease for numerous odorants. No significant differences were found in olfactory identification, detection thresholds, or sensitivity compared to healthy controls. Despite the non-significant results, there did appear a trend of poorer olfactory abilities in Kidney Disease participants. The differences in olfactory performance also varied from odorant …

Examination Of Personality Characteristics Among Cybersecurity And Information Technology Professionals, Sarah E. Freed

Masters Theses and Doctoral Dissertations

An influx of cyber-attacks throughout the past decade has resulted in an increase in demand for cybersecurity professionals. However, the rapid growth of this field has led to a general lack of knowledge regarding the characteristics of individuals and job roles of cybersecurity professionals. This study addresses this gap in the existing literature by evaluating personality characteristics among information technology and cybersecurity professionals. Following an analysis of the facets of the IPIP NEO short form, it was discovered that cybersecurity professionals scored significantly different on Trust, Intellect, Vulnerability, Self-Consciousness, Assertiveness, and Adventurousness when compared to other information technology professional indicating …

Role Of The Ventral Tegmental Area And Ventral Tegmental Area Nicotinic Acetylcholine Receptors In The Incentive Amplifying Effect Of Nicotine, Ashley B. Sheppard

Electronic Theses and Dissertations

Nicotine has multiple behavioral effects as a result of its action in the central nervous system. Nicotine strengthens the behaviors that lead to nicotine administration (primary reinforcement), and this effect of nicotine depends on mesotelencephalic systems of the brain that are critical to goal directed behavior, reward, and reinforcement. Nicotine also serves as a ‘reinforcement enhancer’ – drug administration enhances behaviors that lead to other drug and nondrug reinforcers. Although the reinforcement enhancing effects of nicotine may promote tobacco use in the face of associated negative health outcomes, the neuroanatomical systems that mediate this effect of nicotine have never been …

Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm

Department of Psychology: Dissertations, Theses, and Student Research

This dissertation investigates the role of trust in predicting cooperation with a natural resources management institution. It begins with an exploration of the legal landscape against which the relationship between land owners and natural resources management institutions is contextualized, presents a review of the often ostensibly disparate trust literature and a framework for its integration, and proposes and tests a model of trust and cooperation in the natural resources context. The results provide mixed support for the model as proposed but confirm the importance of trust in this context and suggest implications for policy, especially the potential importance of increasing …

Parent Vs. Teacher Ratings Of Children’S Shyness As Predictors Of Language And Attention Skills, Kathleen Moritz Rudasill, Amanda Prokasky, Xiaoqing Tu, Scott R. Frohn, Kate Sirota, Victoria J. Molfese

Department of Educational Psychology: Faculty Publications

Shyness in childhood has been linked to multiple adjustment outcomes, including poor peer relations, internalizing problems, and clinical anxiety. However, shyness does not consistently emerge as a negative predictor of children’s success. This incongruity may stem, in part, from variations in the operationalization and measurement of shyness in different studies. Researchers often combine parent and teacher ratings of shyness, but correlations between parent and teacher reports are consistently small to medium. The purpose of this study is to examine parent and teacher ratings of shyness as they predict language and attention skills in preschool children, and explore discrepancies between parent …

Is ‘How’M I Doin’?’ A Universal Question? Unpackaging Cultural Differences In Feedback Seeking, Rana Gaby Moukarzel

Theses and Dissertations

The feedback literature is based on the premise that given a favorable context and a drive to reduce uncertainties, all individuals should seek self-relevant performance information. However, this framework has only been empirically examined using Western samples and has failed to consider the influence of the broader context, with the exclusion of Sully de Luque and Sommer’s (2000) cultural framework. The purpose of this project was to integrate extant culture theory into the feedback seeking literature for a more comprehensive framework, and a more global understanding of cultural contingencies surrounding the feedback seeking process. Findings revealed the universality of feedback …

The Effect Of Group Level Factors On Affective Convergence In Teams: An Agent Based Model, Chaunette Marie Small

Theses and Dissertations

Previous research supports the idea that affective convergence occurs in teams. The phenomenon of group affect has been well documented, however the group level conditions through which affective convergence emerges has received very little research. The current study helps to fill this gap by using agent-based modeling to examine affective convergence under varying group conditions. Agent-based modeling is a recently developed approach to research that uses the power of computers to model individual level behaviors and examine group level emergent constructs. The current study examined display rule presence, display rule breadth, social influence, interdependence, and team size on affective convergence. …

Talking With Children About Potentially Sensitive Topics: Birth, Sex, Death, And Santa, Natalie Lane Hendricks, Elisabeth Hope Jee, Tiffany Erin Robbins

Psychology and Child Development

Our study looks at conversations between parents/caregivers and their children about potentially sensitive topics including birth, sex, death, and fantastical beings (i.e. Santa Claus, the tooth fairy, the Easter bunny). Our paper covers information on what children know, Parent conversations, and cultural differences between all these topics. Our methods Are broken up into two parts: a parent survey and an informative website. The survey was distributed locally and included questions about parents’ beliefs towards how much their children knew about these topics and their attitudes about having the conversations. The website was created to be a tool for parents and …

Traumatic Life Events And Symptoms Of Anxiety: Moderating Effects Of Adaptive Versus Maladaptive Coping Strategies, Alishia Foster

Electronic Theses and Dissertations

The experience of trauma is prevalent among young adult college students and is often associated with poor mental health outcomes such as symptoms of anxiety. Not all individuals who have experienced trauma, however, develop anxiety, perhaps due to individual-level adaptive characteristics, such as use of adaptive rather than maladaptive coping strategies. Yet, little research has examined the interrelationships between the experience of trauma, specific types of coping strategies, and subclinical anxiety symptoms. A sample of 915 undergraduate students completed self-report measures of trauma, coping strategies, and anxiety symptoms. We hypothesized that traumatic life events would be associated with anxiety symptoms, …

Traditional Masculinity & Advertising Image Approval, Danielle W. Kailing, Peggy Cantrell Phd

Undergraduate Honors Theses

This project investigates the relationship between adherence to traditional masculinity and approval of selected advertising images. Because traditional masculinity includes characteristics supportive of aggression and dominance; I hypothesize that an increase in adherence to traditional masculinity will correlate with approval of the violence found in some print advertisements. Participants include 259 men who completed an anonymous, online, survey. Adherence to masculinity is measured using the Male Role Norm Inventory-Revised (MRNI-R) (Levant, et. al, 2007). Each picture is scored on a 5-point Likert Scale. As hypothesized, an increase in total MRNI-R score, is significantly correlated with an increase in the approval …

Does Nicotine Alter What Is Learned About Non-Drug Incentives?, Tarra L. Baker

Undergraduate Honors Theses

Nicotine is one of the most addictive drugs known to man, yet it has limited reinforcing effects in humans and non-human animals when it is not self-administered in tobacco products. One hypothesis for these paradoxical effects of nicotine is that the effects of the drug in the brain alter acquisition of incentive learning. The hypothesis for this study is that nicotine will increase the value of cues paired with a reward. To test this hypothesis, 26 Sprague Dawley Male rats were randomly assigned to one of three groups Pre-NIC (the critical experimental group), Post-NIC and SAL. Each group received a …

Neuromodulation Therapy Mitigates Heart Failure Induced Hippocampal Damage, Timothy P. Diperi

Undergraduate Honors Theses

Cardiovascular disease (CVD) is the leading cause of death in the United States. Nearly half of the people diagnosed with heart failure (HF) die within 5 years of diagnosis. Brain abnormalities secondary to CVD have been observed in many discrete regions, including the hippocampus. Nearly 25% of patients with CVD also have major depressive disorder (MDD), and hippocampal dysfunction is a characteristic of both diseases. In this study, the hippocampus and an area of the hippocampal formation, the dentate gyrus (DG), were studied in a canine model of HF. Using this canine HF model previously, we have determined that myocardial …

Interleukin-6 And Soluble Interleukin-6 Receptor Levels In Posttraumatic Stress Disorder : Associations With Lifetime Diagnostic Status And Psychological Context., Tamara L. Newton, Rafael Fernandez-Botran, James J. Miller, Vicki Ellison Burns

Faculty and Staff Scholarship

This study correlated lifetime PTSD diagnostic status with interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) levels, and tested whether these correlations are sensitive to psychological context. Midlife women attended two research visits where blood was drawn (beginning of visits) and saliva and oral mucosal transudate were collected (beginning and end of visits) to measure IL-6 and sIL-6R. Women were classified as PTSD−/− (past and current symptoms below subsyndromal levels), PTSD+/− (past symptoms at or above subsyndromal levels), or PTSD +/+ (past and current symptoms at or above subsyndromal levels). PTSD+/+ women, compared to the other women, showed more negative emotion …

Wisc-Iv Profiles In Children With Attention Deficit Hyperactivity Disorder And Comorbid Learning Disabilities, Elyse Parke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention Deficit Hyperactivity Disorder (ADHD) and learning disabilities (LD), including Reading Disorder (RD), Disorder of Written Expression (DWE), and Developmental Coordination Disorder (DCD) all co-occur at high rates. Previous research indicates increased neurocognitive impairment in ADHD with the presence of comorbid diagnoses. However, few direct comparisons between intellectual profiles of children with one or multiple ADHD and LD diagnoses are available, specifically for the Wechsler Intelligence Scale Fourth Edition (WISC-IV), despite its frequent and historical use with this population. Profile analysis may contribute insights into spared and impaired abilities. Therefore, the present study addressed these matters by comparing WISC-IV profiles …

Studies of HIV/AIDS knowledge, attitudes and practices among fishermen in developing countries have shown gaps in knowledge and fear of contagion with ambivalent attitudes towards HIV/AIDS and inconsistent universal precautions adherence. The aim of this study was to determine the knowledge, attitude and practices regarding HIV/AIDS among adult fishermen in a coastal area of Karachi, Pakistan.

METHODS:

Community based cross sectional study was conducted among fishermen in coastal area of Karachi from June to September 2012. A total of 297 adult …

The Effect Of Harsh Parenting On Anxiety Levels In Adolescents As Moderated By Rsa And Family Stability, Laura B. Welburn

Psychology

The present study examines the relation between harsh parenting experienced during adolescence on anxiety symptoms during adulthood as moderated by the parasympathetic nervous system (PNS) activity and family stability. Participants completed questionnaires assessing parenting styles, the regularity or family activities, and current anxiety symptoms (61 adults; mean age = 19.39 years; 50.8% European American; 47.5% male). PNS activity was measured by resting respiratory sinus arrhythmia (RSA). The results suggest that among males, relatively high RSA buffers the effects of harsh parenting on anxiety symptoms. Also, for males, the stability of home life at relatively high levels can be a protective …

The Effects Of Maternal Information Transmission On Daughters' Responding To A Voluntary Hyperventilation Challenge, Ashley Arehart Knapp

Graduate Theses and Dissertations

Contemporary models of panic etiology would benefit from additional tests of how fear of internal cues is acquired. Drawing from literature suggesting parent-to-child verbal information transmission is one pathway by which fear of external stimuli is learned, the current study is designed to address the effects of this pathway on fearful responding to internal cues (i.e., somatic perturbation produced by a voluntary hyperventilation challenge). Specifically, 53 mothers of adolescent females between the ages of 10 and 14 years were randomly assigned to either share negative or positive information regarding their experience with a voluntary hyperventilation challenge prior to their daughters …

Female Relational Aggression: A Case Study Investigation Of The Transitioning Out Process, Lynne Lunsford

Doctoral Dissertations and Projects

The developmental trajectory of relational aggression (RA) can launch as early as preschool and escalate from early to middle childhood, yet it is a phenomenon that may or may not endure the adult years. There is adequate understanding of relational aggression in the active phase, yet research that edifies the transitioning out process is dearth. Through a qualitative case study research design, the narratives of six females who ceased using RA enlightened the process of desistance. All females described the transitioning out process as having an identifiable turning point accompanied by cognitive and emotional shifts associated with recognizing, valuing, and …

The Influence Of Religiosity And Adult Attachment Style On Marital Satisfaction Among Korean Christian Couples Living In South Korea, Dae Woon Cho

Doctoral Dissertations and Projects

The primary purpose of this study was to investigate the influence of religious commitment, spirituality and adult attachment style on marital satisfaction among South Korean Christian couples living in South Korea. Three hundred sixty nine South Korean Christian couples from nine Presbyterian churches in Seoul, Dejeon, Daegu, Gumi, and Busan participated in this research. The current study evaluated the psychometric utility of the Spiritual Assessment Scale (SAS) and investigated the relationships among religiosity (religious commitment and spirituality), attachment style (anxious and avoidant attachment) and marital satisfaction. For the psychometric evaluation of the SAS, Confirmatory Factor Analysis was conducted for the …

The Mental Health Disparity Among Nonheterosexuals: Risk, Resiliency, And New Perspectives To Consider In The Context Of Mormonism, Katherine Ann Crowell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nonheterosexuals disproportionately experience mental illness when compared with heterosexuals. Although it has been well established that the apparent mental health disparity among sexually diverse populations is almost exclusively derived from minority stress (i.e., the excess stress associated with culturally maintained sexual stigma), our understanding of how specific aspects of minority stress lead to specific psychological syndromes (e.g., depression) remains limited. On the other hand, in attempts to destigmatize individuals who do not identify as heterosexual, researchers have increasingly begun to shift the focus of their work towards understanding the specific characteristics or experiences that facilitate individuals’ capacity to adapt and …

Understanding Experiences Of Female Survivors Of Domestic Violence: Stories Of Strength, Resilience, And Mechanisms That Assist In Leaving Violent Relationships, Annel Cordero

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A qualitative study was conducted in order to better understand domestic violence (DV) survivors’ lived experiences and the mechanisms that assisted them in leaving violent relationships. This method of research enabled me to immerse myself within the work in order to better understand this issue from the perspective of the survivors. Through in-depth interviews and focus groups, women were given the space to have their voices heard. For this project, 13 women from two different states, of diverse ages, sexual orientations, and ethnicities who identified as survivors volunteered to tell their stories. To obtain a complete picture of their experiences, …

Contextual Differences In Reinforcement Affect Self-Control In Shr And Wky Subjects, Jonathan C. Rich

Undergraduate Honors Capstone Projects

The spontaneously hypertensive rat (SHR) is the outcome of selectively breeding its progenitor the Wistar Kyoto (WKY) for hypertension. In the present experiment, the context of reinforcement was manipulated to determine its effect on impulsivity across the SHR and WKY strains of rat. An additional block of delays was added onto the end of a standard delay discounting procedure to vary the context of reinforcement from one condition (0 sec.) to the next (60 sec.). Results indicate that both SHR and WKY subjects made fewer impulsive decisions when a shorter delay followed the longest delay in the task - although …

The Definition, Identification, And Cause Of Specific Learning Disabilities: A Literature Review, Joseph M. Cottrell

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Students with specific learning disabilities (SLDs) currently make up approximately 40% of students receiving special education. The definition of SLD has not changed since the original special education law was implemented in 1975. Even with the recent changes to special education law in 2004, the definition stayed the same. Some professionals believe this lack of change reveals consistency while other scholars believe this lack of change reveals a lack of knowledge about what SLDs really are. The definition of SLD gives little insight regarding the etiology of the disorder. There are three prominent theories regarding the cause of SLDs: (a) …

Biopsychosocial Variables Predict Compensation And Medical Costs Of Radiofrequency Neurotomy In Utah Workers' Compensation Patients, Amie L. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Back pain is one of the most expensive medical conditions to treat. There has been a great deal of research showing that back pain surgery is expensive, but less is known about the costs of less-invasive spine procedures such as radiofrequency neurotomy. Radiofrequency neurotomy is used to treat facet joint pain and typically offers temporary pain relief by coagulating the affected nerve with radiofrequency waves to block pain messages from reaching the brain. This study aimed to document the costs of radiofrequency neurotomy in a group of participants who received the procedure through the Workers’ Compensation Fund of Utah (WCFU). …

Self-Reported Psychopathology Correlates Of Homeless Youth In Utah, Kimberlee Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Homelessness among unaccompanied youth is a unique, yet pervasive, social problem. Youth often become homeless through three central pathways: conflict with family, involvement in the foster system, and involvement in juvenile justice systems. As youth experience homelessness during important developmental period(s), vulnerability to mental illness may occur if not already present. The present study examined the type and prevalence of mental illness. Characteristics of homelessness, health and mental health service utilization, and pathways to homelessness were examined in relation to the occurrence of mental illness. Findings indicated that a variety of characteristics are associated with mental illness. Mental health service …
