Latina/O First Generation College Students And College Adjustment: An Examination Of Family Support Processes, Patricia R. Cerda-Lizarraga

College of Education and Human Sciences: Dissertations, Theses, and Student Research

First generation Latina/o college students are at a higher risk for not completing their college degrees when compared to other ethnic minorities due to added barriers and challenges of being the first to go to college. Researchers reported that poor college adjustment is one of the factors contributing to the lack of college completion among Latina/o college students. A few studies exist on the role that family support has on the college adjustment of Latina/o students and these yielded mixed findings. The central role of the family among Latina/o students and their support during the college adjustment period merits attention. …

An Evaluation Of The Validity Of A Script-Driven Imagery Procedure Among Traumatic Event Exposed Adolescents, Emily Renae Mischel

Graduate Theses and Dissertations

Extensive research suggests script-driven imagery procedures employed with traumatic event-exposed adults produce reliable reactions that map onto contemporary models of posttraumatic stress, including increased physiological (Carson et al., 2000; Orr et al., 1998; Ramón et al., 2006) and negative affective (Pitman et al., 1987) responses to trauma scripts. Therefore, such procedures can be utilized in a controlled, laboratory-based setting, supporting mechanism-oriented research designed to better understand the nature, correlates, and consequences of traumatization and posttraumatic stress symptoms (PTSS). Unfortunately, only one study has begun to evaluate the validity of script-driven imagery procedures for use with youth, making further investigation of …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

Impact Of Heart-Rate Variability Biofeedback On Major Depression Disorder In Resting-State Fmri, Hiu Wai Caldwell

Theses and Dissertations

Major depressive disorder (MDD) is one of the most common psychiatric illnesses and causes significant disturbances in daily functioning. Research on heart-rate variability (HRV) biofeedback training suggests that HRV is an efficacious adjunct to psychotherapy in reducing depressive symptoms. The purpose of this study was to examine neurological changes in depressed individuals who were randomized to either a psychotherapy plus HRV biofeedback training or to a treatment as usual group. A control group with no history of depression was also studied. We collected psychological, physiological, and imaging data from 30 participants (10 in an experimental group, 10 in a treatment …

The purpose of this study was to understand Mexican immigrant mother's perceptions concerning parental involvement with their children's schools. It provides a perspective on cultural considerations relevant to the implementation of Epstein's model of parental involvement. Eight mothers, two documented and six undocumented, who had emigrated from Mexico and were living in rural Wyoming, were interviewed. The information provided by the participants included descriptions of practices the mothers considered meaningful when involved with their children's education. They shared their own experiences of their school attendance in Mexico and their own parents' involvement with their education. They also shared their understanding …

Mothers' Views Of Their Children's Anxiety In Autism: A Qualitative Approach, Jessica Mae Palilla

Theses and Dissertations

Children diagnosed with autism spectrum disorders (ASD), which is marked by severe social disabilities, also present with higher rates of anxiety. Understanding the qualitative symptoms that underlie anxiety in ASD may help to better characterize the overlap of ASD and anxiety symptomology and suggest targeted treatment strategies. Twenty mothers with male children diagnosed with high-functioning ASD were interviewed using a follow-up interview to the SCAS parent rating scale, in order to better understand how mothers perceive their child's anxious thoughts, behaviors and cognitions. All interviews were transcribed and thematic analysis was used to analyze the results. Eight themes emerged from …

Integration Of Audio-~Visual Emotional Information In Schizophrneia, Bern Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia (SZ) is a debilitating illness characterized by a number of perceptual and

cognitive deficits. Deficits in emotional judgment and perception are consistently identified, although less is known about the integration of emotional information from separate sensory modalities. This study investigates the integration of auditory and visual emotional information in schizophrenia and healthy controls through application of an emotion judgment task modeled after the McGurk effect. The emotional judgments of 54 participants (40 SZ and 14 control participants from the community) for auditory, visual, and bimodal phonemic stimuli conveying no lexical information were analyzed. Visual and auditory stimuli conveying joy …

Differences In Absenteeism Severity Among Community Youth, Kyleigh Kay Sheldon

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined the relationship between school absenteeism severity and specific clinical and family variables in 118 middle and high school youth aged 11-19 years recruited from two truancy settings. The primary aim was to determine specific clinical and family variables that may be predictive of absenteeism severity in community youth. A secondary aim was to examine the level of absenteeism that warrants the most clinical concern. Hypotheses for the proposed study were based on the premise that characteristics of a community sample of youth with problematic absenteeism would generally resemble those identified in previous clinical samples. The first set …

Rape Perception Based On Religious Orientation, Gender, And Length Of Relationship, Julie A. Herweyer

All NMU Master's Theses

Rape victims face many difficulties after the traumatic event, one of these being inadequate social support. Victims frequently report apathetic, insensitive, or accusing reactions from support systems (Ahrens, 2006). Understanding how peers respond is essential for ensuring sufficient support is provided. This study explored how college students may perceive victims as predicted by participants’ gender, religious orientation, attitudes toward permissiveness, and length of relationship between victim and perpetrator. Also, order in which participants were asked about their sex was examined as a predicting variable. Participants were randomly assigned to read a vignette featuring a couple that had been dating for …

An Examination Of Psychological Climate Linking Mechanisms Across The Strategic Priorities Of Health And Stress, Alec Munc

All Dissertations

Given that employee health and well-being represent a significant source of financial costs for organizations, this dissertation seeks to address some of the pathways through which organizational efforts to improve physical and mental health may operate. This study drew from a model of safety climate (Neal & Griffin, 2000) to propose that psychological climate exerts in influence on employee health and well-being through the joint moderators of knowledge/motivation and behaviors. The model also extended beyond the typical climate linking mechanisms to include moderators both individual (behavioral activation & behavioral inhibition systems) and contextual (workplace physical exposure). Using a two-wave prospective …

Short-Term Effects Of A Western Diet On The Number Of Brainderived Neurotrophic Factor Immunoreactive Neurons In The Hypothalamic Arcuate, Ventromedial And Paraventricular Nuclei, Kaitlyn Elizabeth Gilland

Open Access Theses

Brain-derived neurotrophic factor (BDNF) is an important anorexogenic factor and has been shown to be involved in obesity. It is important to know when changes in BDNF expression occur to possibly prevent development of dietary obesity. BDNF mRNA decreases in response to long-term western diet (WD) exposure in the ventromedial hypothalamus (VMH), yet no study has investigated the short-term effects of WD on BDNF expression in the hypothalamus. It was hypothesized BDNF protein would mirror a decrease in BDNF mRNA in the VMH when mice were fasted for 48-hours or fed WD for 6-hours, 48-hours, 1-week and 3-week and decrease …

Psychology Department Faculty Publications

This study examined the experiences, adaptations, observations, and insights on the use of Psychological First Aid (PFA) in the Philippines. Nineteen PFA providers who were trained in the basics of PFA from three major cities in the Philippines took part in this study. Respondents' knowledge about PFA was consistent with the core principles of promoting a sense of safety, calm, self-and community efficacy, connectedness, and instilling a sense of hope. The delivery of PFA was adapted to the Filipino culture through the use of local counseling models, a group-based setup , and the use of mindfulness and relaxation techniques. The …

A Social Cognitive Approach To Disaster Preparedness, Ervina Espina, Mendiola Teng-Calleja

Psychology Department Faculty Publications

Using the social cognitive perspective, the study sought to determine the individual and environmental factors that predict disaster preparedness. Specifically, the research determined the relationships between risk perception, disaster experience, community disaster preparedness, and disaster preparedness behaviors. Data were collected from 401 participants from areas affected by recent typhoons and heavy monsoon rains: Tacloban and Metro Manila. Risk perception, severity of disaster experience, and community disaster preparedness were found to significantly predict the participants’ disaster preparedness behaviors. Severity of previous disaster experience seems to be the strongest determinant of individual disaster preparedness. Implications to future research and development and improvement …

Vicarious Trauma And Natural Disasters: A Transcendental Phenomenological Analysis Of The Experiences Of Families Of Typhoon Haiyan Survivors, Arvin Jeremy N. Tan, Andrew O. Jardeleza, Florian Antoinette P. Sta Maria, Mendiola Teng-Calleja

Psychology Department Faculty Publications

Using transcendental phenomenology, we examined the experience of vicarious trauma in the context of natural disasters. We specifically looked at the narratives of domestic migrants whose family members were Typhoon Haiyan survivors. Findings show that the survivors’ families experienced painful and intrusive psychological distress. The gravity of the pain and loss experienced by the participants was relative to the amount of pain, loss, or damage sustained by the subject of their attachment. Vicarious trauma was experienced as a void-filling phenomenon occupying the emotional space created by the physical distance of the participants from their families experiencing the disaster. This phenomenon …

Problem Solving And Tool Use In Three Species Of Otter, Robert F. Gormley

Masters Theses and Doctoral Dissertations

Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis predicts complex cognitive capacities in socially complex species. Using the Aesop’s Fable paradigm – wherein subjects drop stones into a cylinder half-filled with water to acquire floating out-of-reach food items – I assessed North American river otters’, Asian small-clawed otters, and giant river otters abilities to solve a novel tool-mediated problem. Sticks and water were presented with the …

Nurses’ Perceptions Of Self As Role Models Of Health, Shelia Hurley

Electronic Theses and Dissertations

Given the sad state of obesity and lifestyle-related illnesses in the US, nurses, as the largest and most trusted health profession, must take the cause of health promotion seriously and personally. This study seeks to close the gap in knowledge of nurses’ perception of self as a role model of health and personal healthy lifestyle behaviors. This study focuses on four specific behaviors that lead to a healthy lifestyle: limit alcohol, avoid tobacco, improve nutrition, and engage in physical activity. The purpose of this study is to determine the relationship between nurses’ health practices and their perceptions of self as …

Person-Corporate Social Responsibility Fit: Considering The Effects Of Corporate Values On Fit Within The Organization, Brittney Winters

Electronic Theses, Projects, and Dissertations

Corporate social responsibility (CSR) is an expanding trend as more organizations have adopted various CSR policies. Due to this, CSR has been a growing topic in Business and Psychology research, especially on the micro-level of CSR’s effects on individual employee outcomes. In this study, we proposed a new sub-dimension of Person-Organization (P-O) fit, such that there’s a Person-CSR (P-CSR) fit: the perceived congruence between an individuals’ values with an organization’s CSR initiatives. We predicted that P-CSR fit would explain additional variance over and beyond P-O fit for organizational outcomes: organizational commitment, organizational identity, job satisfaction, and organizational citizenship behaviors. Further, …

Dispositional Employability And The Relationship To Career Success: A Meta-Analysis, Alisha M. Jasmer

Electronic Theses, Projects, and Dissertations

This meta-analysis focuses on the willingness to work aspect of the RAW model of employability of Hogan et al. (2009), in relationship to career success. Willingness to work (W) can be defined as favorably disposed to work hard and take initiative at one’s job. The variables I used to structure the W are proactive personality, conscientiousness, work ethic, job involvement, adaptability, and ambition.

I used the Hunter and Schmidt method to analyze the data applying a random effects model. All calculations were conducted in Excel. The overall sample consisted of 100 effect sizes (r) derived from 41 studies. The total …

“God Hates Fags”—The Use Of Religion As Justification For Prejudice Towards Homosexuals, Michelle S. Fabros

Electronic Theses, Projects, and Dissertations

The Westboro Baptist Church and Phelps family are notorious for their signs proclaiming anti-homosexuality epithets such as “God Hates Fag,” and references to Biblical verses to revile homosexuality (e.g., Romans 1:24-27). Although the homonegativity bias that Westboro patrons and many traditional Christians express is often understood as being rooted in religion, I proposed the possibility that religion can be a justification rather than source of homonegativity. That is, although religion typically is seen as the source of prejudice towards LGBT+ people, I argued that this relationship might work in reverse. I examined under which conditions this “reverse” phenomena might occur …

Examining Resilience In Relation To Ptsd Symptomatology In Maltreated Youth, Timothy Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resilience following exposure to adverse life situations is an ongoing process that reduces the impact of traumatic experiences and opens potential for posttraumatic growth (Fincham, Altes, Stein, & Seedat, 2009; Luthar, Cicchetti, & Becker, 2000). The relationship between resilience and risk for PTSD in maltreated youth, however, remains unclear. This study sought to explore this relationship by examining a sense of mastery, a sense of relation to others, and emotional reactivity in youth endorsing a history of maltreatment related trauma. Participants were recruited from a Las Vegas Department of Family Services affiliated clinic and were administered the Children’s PTSD Inventory …

Examining The Dynamics Of Infant Face Processing Using State Space Grids, Andrea Jane Kayl

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this investigation we examined the potential processes underlying infant preferences for and categorization of male and female faces as well as the outcome of these preferences. Infants with female primary caregivers exhibit preferences for same-race females over males and categorize females more readily than males. Little is known, however, about how infants may arrive at these collective preferences and categorization abilities. In research settings infants are exposed to novel stimuli in relatively short periods of time, and their experiences outside of the lab may be imposing structure onto their learning in lab settings. We used state space grids (SSGs) …

Experiencing Parental Loss During Adolescence And Factors Influencing Hospital Involvement And The Grieving Process, Vaida Kazlauskaite

UNLV Theses, Dissertations, Professional Papers, and Capstones

Experiencing the death of a loved one can be traumatic and painful to anyone. Adolescents in particular experience death in a unique way, during a time in their lives when they are developing their own autonomy and independence. Experiencing the deteriorating conditions of a terminally ill parent may affect an adolescent in many ways. However, there is relatively little research on adolescent involvement in the medical setting during a parent’s terminal illness and how this may affect the adolescent’s bereavement. This qualitative study utilized heuristic inquiry and procedures of Grounded Theory to investigate factors influencing the involvement in the hospital …

What Do We See: Number Line Estimation With Eye Tracking, Sarah Ann Salas

UNLV Theses, Dissertations, Professional Papers, and Capstones

The following paper presents a study investigating adult number line estimation patterns through use of an eye tracker. Estimation patterns were examined by changing the range of the number line on which the estimations occur from the typical ranges of 0-100 and 0-1000 to a more difficult range of 0-723. There were two main conditions of the experiment; in one condition the number to estimate and the number line were presented simultaneously, and in the other condition, the number line presentation was delayed. In each of the two conditions of the experiment, eye fixations and area of interest analysis were …

The Experience Of Participating In Des, Dio Turner Ii

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Descriptive Experience Sampling method (DES, Hurlburt, 1990, 1993) is designed to help researchers collect and describe participants’ inner experience in a way that minimizes the impact of the participant’s presuppositions and the researcher’s worldview on the description of participants’ inner experience. This study was an exploratory examination of the potential therapeutic effects of DES. It used three sources of data: pre and post-DES SCL-90-R questionnaires, observation of the process that unfolded during DES interviews, and a post-DES exit interview. Participants (n = 14) were drawn from the Psychology 101 Subject Pool. After five days of DES, there was a …

Examining The Inner Experience Of Individuals With Bipolar Disorder, Johanah Yoosun Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder (BD) is a serious, chronic mood disorder. The diagnostic criteria for BD provide a description of expected experiences of individuals with BD (e.g., sadness, expansive mood, inflated self-esteem, anhedonia). Despite these criteria, the details of inner experience of individuals with BD are generally unknown. Understanding the inner experience of individuals with BD may provide greater understanding of the lived experience of BD and may provide insights into treating BD. The present study examined the inner experience of six individuals with BD using Descriptive Experience Sampling (DES), a method aimed at apprehending high- fidelity accounts of momentary inner experience. …

Reducing Eating Disorder Risk Factors: A Pilot Effectiveness Trial Of A Train-The-Trainer Approach To Dissemination And Implementation, Rebecca Greif, Carolyn Becker, Tom Hildebrandt

Psychology Faculty Research

Objective: Impediments limit dissemination and implementation of evidence-based interventions (EBIs), including lack of sufficient training. One strategy to increase implementation of EBIs is the train-the-trainer (TTT) model. The Body Project is a peer-led body image program that reduces eating disorder (ED) risk factors. This study examined the effectiveness of a TTT model at reducing risk factors in Body Project participants. Specifically, this study examined whether a master trainer could train a novice trainer to train undergraduate peer leaders to administer the Body Project such that individuals who received the Body Project (i.e., participants) would evidence comparable outcomes to previous trials.We …

Physiological Response To Dissonance In Musicians And Nonmusicians, Angela Beth Biehl

Masters Theses

Knowing the human response to musical dissonance could have important therapeutic implications in the music therapy setting. The listener’s musical experience could significantly impact their response and subsequently its effect in a therapeutic setting. Thus, this study aimed to examine both the psychophysiological and subjective responses to dissonance and the difference in these responses between those with high experience and those with low experience. Participating groups, categorized as high experience (HE) and low experience (LE) in terms of musical knowledge, listened to consonant and dissonant musical excerpts, and rated each excerpt on its pleasantness; their physiologic responses were measured to …

Grooming Habits And Self-Perceptions Among Emerging Adults, Madeline A. Dunton

Honors College Theses

The recent increase of use of the dating websites and applications has called to question whether the use of these dating websites and applications causes emerging adults to place greater emphasis on their grooming habits, and if this emphasis is driven by a desire for sexual partners. The purpose of this study was to see whether an emerging adult’s daily grooming habits are influenced or affected by self-perceptions, and if there was a relationship between emerging adults’ sexual activity and grooming habits. The distribution of a self-report survey to 267 college-aged students regarding the use of grooming products and ratings …

It’S All In How You Use It: Managers’ Use Of Meetings To Reduce Employee Intentions To Quit, Joseph E. Mroz, Joseph A. Allen

Psychology Faculty Publications

Meetings are often viewed as unnecessary, wastes of time, and overall negative experiences at work. In this study, we examined the positive side of meetings, specifically, how the relationship a manager fosters with subordinates in meetings affects those employees’ intentions to quit (ITQ). Using an online survey of working adults who regularly attended meetings, we found that the relation between perceived organizational support (POS) and leader–member exchange (LMX) quality in meetings on ITQ depended on an employee’s level of negative affectivity (NA). When POS or LMX in meetings was low or average, high-NA employees held significantly higher ITQ than low-NA …

Factor Analysis Of The Sport Interference Checklist With Collegiate Athletes, Travis Albert Loughran

UNLV Theses, Dissertations, Professional Papers, and Capstones

There are a variety of cognitive and behavioral factors that have been indicated to have a negative impact on sport performance. College student-athletes may be at particular risk to evidence problems that interfere with optimal sport performance due to high physical, social, and emotional demands. To fully understand what factors influence student-athlete sport performance, appropriate, psychometrically validated assessment measures are needed. The Sport Interference Checklist (SIC) is an assessment tool that was developed to assess sport performance in both training and competitive situations for student-athletes. The SIC includes two scales, the Problems in Sport Training Scale (PSTS) and the Problems …
