Posttraumatic Stress Disorder In Maltreated Multiracial Youth, Harpreet Kaur

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lemos-Miller and Kearney (2006) first identified depression as a meditator of (1) dissociation and posttraumatic cognitions and (2) PTSD in maltreated children. In addition, they found that African American status weakened the mediating relationship, whereas multiracial status strengthened the mediating relationship. Multiracial youth in Lemos-Miller and Kearney's study experienced a stronger relationship between depression and PTSD than other ethnic groups.

The present study evaluated the Lemos-Miller and Kearney (2006) model of PTSD among a larger sample of multiracial youth. The present study sought to identify whether the Lemos-Miller and Kearney (2006) finding regarding multiracial youth could be replicated. The presented …

Cognitive Differences Between High And Low Responders Of A Tier Ii Reading Intervention, Jillian Cohen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study evaluated a population of young students with potential reading disabilities who participated in a large western school district's Reading Skills Development project from October 2012 to May 2013. The following questions were addressed: Are there cognitive differences between students who respond well to an intense Tier II reading intervention and those who make little progress? If so, which cognitive skills best discriminate between high and low responders? De-identified data was collected from 171 struggling readers in 1st through 3rd grade who participated in the Reading Skills project. After controlling for English proficiency level, high and low responders were …

Attributions And Coping Behaviors Communicated Among Bullied Students: An Analysis Of Bullying Blogs, Carly Marie Danielson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student bullying is a growing and damaging problem in society today. This study investigates the role of bullied students' attributions and coping strategies through Heider's (1958) attribution theory (AT) and Crick and Dodge's (1994) social information processing model (SIP). Rich data are obtained from bullying blogs that showcase how bullied individuals make sense of their experiences online. The important findings that emerge from this investigation relate to similarities in men's and women's attributions and differences in their coping strategies and resources to manage victimization. Additionally, both men and women experienced similar negative outcomes with particular coping strategies and resources, suggesting …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

School Climate, Absenteeism, And Psychopathology Among Truant Youth, Marisa Charlene Hendron

UNLV Theses, Dissertations, Professional Papers, and Capstones

School refusal behavior has become highly problematic for schools worldwide. Researchers have focused efforts on examining many factors related to absenteeism, including child, parent, family, peer, school, and community variables. Many previous researchers examined absenteeism between groups (i.e. truants vs. nontruants, truants vs. school refusers). The present study investigated percentage of absenteeism in relation to contextual variables in a diverse sample of truants referred to programs designed to improve attendance. First, a model of school climate (Sharing of Resources, Order and Discipline, Parent Involvement, Student Interpersonal Relations, and Student-Teacher Relations) contributing to severity of absenteeism was tested via structural equation …

The Effect Of Early Life Stress On Methamphetamine Damage In The Striatum, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Methamphetamine (METH) abuse impacts the global economy through costs associated with drug enforcement, emergency room visits, and treatment. Hyperthermia is a leading cause of METH induced emergency room visits and may lead to neural damage. Previous research has demonstrated early life stress, such as childhood abuse, increases the likelihood of developing a substance abuse disorder. However, the effects of early life stress on neuronal damage induced by chronic METH administration are unknown. We aimed to elucidate the effects of early life stress on METH induced dopamine damage in the striatum. Animals were separated three hours per day during the first …

A Model Of Hospitality Employee Engagement, Hee Jung Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on employee's state-like psychological resources by investigating individual and organizational antecedents to employee engagement and valued human resource outcomes. The purpose of this study was to develop and test a theoretical model that explains the interrelationships among six constructs and to explore the mediating effects of employee engagement. Structural Equation Modeling using AMOS (18.0) statistical software was used to test the full structural model (measurement and structural model) of the hypothesized relationships among the variables with a sample of hospitality employees. The findings supported all hypothesized relationships except the direct relationship between employee engagement and turnover intention. …

The Mental Organization Of People's Permanent And Situational Attributes, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis investigated whether readers would integrate physical descriptions of characters into one coherent mental representation or if they would keep mental representations separate. The integration of multiple concepts has been examined in the context of the fan effect, which is the finding that an increase in the number of learned associations for a concept can result in an increase in retrieval times and error rates (Anderson, 1974). However, there is typically not a fan effect when people are able to organize the related information into a single integrated situation model (Radvansky & Zacks, 1991). Previous studies investigating the fan …

What's Age Got To Do With It? Examining How The Age Of Stimulus Faces Affects Children's Implicit Racial Bias, Erica Cheree Noles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Discrepant results regarding the emergence of children's implicit racial bias suggest additional research is needed to understand the developmental timeline of racial bias. Investigations using established explicit racial bias measures and the implicit association task with children demonstrate racial bias in young children (Aboud, 1988; Baron & Banjai, 2006). These findings do not corroborate the only known developmental use of the affective priming task (APT) to measure racial bias, which suggests implicit racial bias does not emerge until adolescence (Degner & Wentura, 2010). Variations in the task demands, the types of stimuli used to represent the construct of race, and …

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 …

Incentivizing Children's Fruit And Vegetable Consumption: Evaluation And Modification Of The Food Dudes Program For Sustainable Use In U. S. Elementary Schools, Brooke A. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Researchers in the Psychology Department and the Nutrition, Dietetics, and Food Sciences Department sought to improve elementary school children’s in-school fruit and vegetable (FV) consumption. To achieve this goal, a program that has proven effective in the UK called the Food Dudes (FD) program was implemented in six local schools. Schools were assigned to either experience the traditional FD program (with prize rewards, such as pencil cases and bubbles), a modified version of the FD program (with praise rewards replacing the prize rewards), or no FD program (the control group). Students who consumed a pre-specified amount of FV each day …

Five-Year Prospective Evaluation Of The Development Of Borderline Symptoms In Psychiatrically Hospitalized Adolescents Who Engage In Deliberate Self-Harm And Suicide-Related Behaviors, Kendra J. Homan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Borderline personality disorder (BPD) is a form of psychopathology characterized by a pervasive pattern of instability with emotion regulation, impulse control,
interpersonal relationships, and sense of self. Research indicates that the majority of individuals with BPD engage in some form of deliberate self-harm (e.g., suicide attempts, nonsuicidal self-injurious behavior) or suicide-related behavior (e.g., suicidal ideation, suicide threats). Longitudinal data from 132 adolescent psychiatric inpatients who were hospitalized for deliberate self-harm and suicide-related behavior and followed for five years was used to investigate whether deliberate self-harm or suicide-related behaviors predicts BPD. Suicide threats were the only variable found to be predictive …

Does The Way Exposure Exercises Are Presented Matter? Comparing Fear Reduction Versus Fear Toleration Models, Ellen J. Bluett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Exposure therapy is considered to be a first line treatment for a variety of anxiety disorders as supported by several review studies. However, there is no clear understanding of how it works. The present study examined how framing exposure exercises impacted outcomes in socially anxious individuals. We conducted a brief two-session exposure-based intervention, including experiential exercises from each therapeutic rationale, with homework assigned between sessions. We were specifically interested in the efficacy of four brief skills interventions: (a) fear reduction, (b) psychological flexibility, (c) values rationale, and (d) control for reducing public speaking anxiety from first to second exposure session. …

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 …

The Influence Of Parental Mental Health And Family Psychosocial Functioning On Bystander Behavior Of Elementary School Children, Joanna C. Jenkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Being the victim of school bullying is associated with many negative outcomes, including depression, anxiety, substance abuse, school refusal, and suicide. Peer bystanders are present in the majority of bullying situations and bystander intervention has been found to be very important in ending a bullying incident. However, most of the time bystanders do not step in to help the victim. The present study investigated the impact of parent and family influences on children’s bystander behavior. Seventy-three third- through sixth-grade students were given a questionnaire that asked about their behavior in bullying situations (engaging in bullying behavior, helping or encouraging the …

The Role Of Self-Concept In Consumer Behavior, Marisa Toth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding the influences underlying consumption has become an increasingly important goal for marketers. This study examined the role of self-concept in consumer behavior, specifically product evaluation. The influences of various dimensions of the self-concept are examined in regard to four product dimensions: public luxury, public necessity, private luxury, and private necessity. Differences due to variations in individual levels of self-monitoring are also measured. Overall, results showed that the more conspicuous a product is (higher on luxury/public dimensions) the greater the relationship between evaluation and ideal self-images (ideal self and ideal social self) for both high and low self-monitors.

Experiencing Psycholoy: Ap/Ib Psychology For High School Students, Tracy Ksiazak, Mary Ford, Ansley Taylor Corson

Arthur Vining Davis High Impact Fellows Projects

We developed a series of experiential activities to increase students’ analysis, synthesis, and evaluation of psychology concepts. These application activities can enhance existing curriculum units on Personality, States of Consciousness, and Dysfunctional Behavior. Three lessons are presented. The first is a lecture and partner application activity that can serve as a bridge between a curriculum unit on States of Consciousness and a curriculum unit on Personality. In this partner application activity, students record their dreams, then work with partners to analyze those dreams from the perspectives of Sigmund Freud, Carl Jung, and the modern psychologist Clara Hill. The second activity …

When It Feels Good To Be Bad: The Effect Of Guilt On Self-Enhancement, Jaclyn Moloney

Theses and Dissertations

The present study aimed to expand on previous research that explains when affect can influence subsequent judgments in an incongruent way. It also investigated a context where a negative emotion may have been maintained in order to achieve a subsequent goal. Participants in a guilt, shame, and control condition visualized past events. Those in the guilt and shame condition wrote about a time when they committed a moral transgression and were instructed to write an apology letter to a person they hurt. They then rated themselves on a number of interpersonal traits as a way to measure self-enhancement. I hypothesized …

Stress And Coping As A Function Of Experience Level In Collegiate Flight Students, Jennifer Kirschner, John Young, Richard Fanjoy

Journal of Aviation Technology and Engineering

Aviation as an industry requires a high degree of precision at all times. Large amounts of stress have been known to decrease performance to undesirable levels. While stress reactions and the coping skills used after encountering stressful situations differ from person to person, generalities can be made by comparing differences between groups. A large number of pilot applicants receive initial training within a university flight program each year. In order to better understand the perceived stress level and the coping skills used by these students, the current research project administered a perceived stress test and a coping skills inventory to …

The Diathesis-Stress Model Of Corruption By The Ruling Ring: Nature, Power, And Exposure In J. R. R. Tolkien’S The Lord Of The Rings, Faith R. Holley

Student Scholarship

In J. R. R. Tolkien’s The Lord of the Rings, the One Ring seems to exert power over some characters more than others. Though these differences could seem like an oversight or a lack of continuity, they also offer the opportunity to examine the effects of the differential power of the Ring. If the Ring is addictive, as Tom Shippey claims in The Road to Middle Earth, then it is possible to examine the etiology of addiction to the Ring (126). In this thesis, I present a psychological reading of Tolkien that relies on a modern psychological theory, namely the …

Openness, Neuroticism, Conscientiousness, And Family Health And Aging Concerns Interact In The Prediction Of Health-Related Internet Searches In A Representative U.S. Sample, Tim Bogg, Phuong T. Vo

Psychology Faculty Research Publications

Recent estimates suggest 60 % of the U.S. adult population uses the Internet to find health-related information. The goal of the present study was to model health-related Internet searches as a function of an interdependent system of personality adaptation in the context of recent health and aging-related concerns. Assessments of background factors, Big Five personality traits, past-month health and aging-related concerns, and the frequency of past-month health-related Internet searches (via Google, Yahoo, AOL, Bing, or some other search engine) were obtained from a representative U.S. sample (N = 1,015). Controlling for background factors, regression analyses showed more frequent health-related …

Perceptions Of Others' Political Affiliation Are Moderated By Individual Perceivers' Own Political Attitudes, John Paul Wilson, Nicholas O. Rule

Department of Psychology Faculty Scholarship and Creative Works

Previous research has shown that perceivers can accurately extract information about perceptually ambiguous group memberships from facial information alone. For example, people demonstrate above-chance accuracy in categorizing political ideology from faces. Further, they ascribe particular personality traits to faces according to political party (e.g., Republicans are dominant and mature, Democrats are likeable and trustworthy). Here, we report three studies that replicated and extended these effects. In Study 1a, we provide evidence that, in addition to showing accuracy in categorization, politically-conservative participants expressed a bias toward categorizing targets as outgroup members. In Study 1b, we replicate this relationship with a larger …

The Romance Of Leadership: Construct Clarification And Its Relationship With Reactions To Organizational Change, Cari Lois Rottman

Dissertations

Leadership involves the dyadic relationship between a leader and his or her followers. As such, the thoughts and attitudes of followers are an integral part of this relationship. Romance of leadership (ROL) is the degree to which followers believe that leadership “is the premiere force in the scheme of organizational events or occurrences” (Felfe, 2005; Meindl & Ehrilich, 1987). The current research examined ROL by looking at 1) the dimensionality and construct validity of ROL, 2) the difference between explicit and implicit measurement of ROL, and 3) the relationship between ROL and evaluations of leader effectiveness in a changing environment. …

Connecting The Dots: An Economic Study Of Parental Factors Shaping Early Childhood Cognitive Development, Bryn Alexandra O'Neill

Business and Economics Honors Papers

This study investigates how maternal and paternal employment status and educational attainment, coupled with parental time and educational inputs such as toys, books, etc. devoted to children, have impacted young children's cognitive development in the U.S. Cognitive development comprises the intellectual and conscious thinking growth that begins in infancy. It involves problem solving, reasoning and memory aptitudes and is tested for throughout each year of childhood in various ways. The impact of the use of external childcare in lieu of parental time on development is also evaluated. This paper will outline reviewed literature, a theoretical model, data discussion, model construction …

The Impact Of Experiential Avoidance On The Relationships Among Military Sexual Trauma, Excessive Behaviors, And Health-Related Outcomes In Female Veterans, Natalie Kate Nugent

Master's Theses and Doctoral Dissertations

Military Sexual Trauma (MST) as defined in United States Public Law, refers to inappropriate sexual conduct, assault, or harassment experienced by a military service member during his or her course of active duty or active duty for training (38 U.S.C. § 1720D). MST has emerged as a distinct form of trauma, resulting in different and often more severe sequelae than other forms of civilian sexual assault and/or non-sexual trauma. This study sought to explore the potential moderating and mediating roles of experiential avoidance on the relationship between MST and health outcomes in an attempt to identify a unifying mechanism through …

The Division Of Family Work Among Fathers And Mothers Of Children With An Autism Spectrum Disorder: Implications For Parents And Family Functioning, Paula L. Ogston-Nobile

Theses and Dissertations

n often ignored aspect of parenting and family work is the responsibility-related caregiving (i.e. the monitoring, arranging, and planning) that is done to ensure that a child is cared for. Among fathers and mothers who have a child with an autism spectrum disorder (ASD), the intensity of meeting these needs is greater than for a typically developing child (e.g. additional coordination of schooling, interventions, healthcare, recreation, respite, and after-school services). As is the case for all parents, they must also attend to the demands of household labor (e.g. car maintenance, groceries, laundry, yard care), nurture their relationships (e.g. partner, friends, …

Children's Experiences With Relational Aggression And Their Disclosure To Their Friends: An Evaluation Of Dyads, Friendship Networks, And Peer Groups, Jayme Lee Jones

Theses and Dissertations

Relational aggression is a devastating problem that has long-lasting consequences for children, especially girls. Although some studies have found that girls who disclose more to their friends experience higher levels of relational aggression, other studies have found that those who experience aggression disclose less than those who do not experience aggression. It is possible that this difference is related to the type of friendships being assessed and who is describing the friendship (i.e., self-report versus peer report). The purpose of this study was to expand on previous research regarding self-disclosure and relational aggression by addressing these differences. First, this study …

The Effects Of An Academic Values Clarification Exercise On Academic Performance Of College Students, Dana Goetz

Honors Theses

Values exploration exercises, in which individuals are typically asked to rank order their values and describe values that are most important to them, have been used for many purposes including reducing the racial achievement gap in academic performance (Cohen, Garcia, Apfel, Maseter, 2006), increasing acceptance of health related issues (Harris & Napper, 2005), and increasing academic success (Chase, Houmanfar, Hayes, Ward, Vilardaga, & Follette, 2013). However, little research has addressed the mechanism or mechanisms through which values clarification exercises impact outcomes, particularly academic achievement. This paper analyzes values clarification exercises used in educational settings during the 1970s and the roles …
