Creating A More Ecologically Valid Decision Task, Kevin L. Kenney May 2016

Creating A More Ecologically Valid Decision Task, Kevin L. Kenney

Master's Theses or Doctor of Nursing Practice

There has been a standing debate in the field regarding the effectiveness of frequencies and probabilities to accurately convey information. This study utilized a naturalistic sampling procedure to determine risk preferences on binary choice decision using time, sex, and goal deficit variables as predictors. Participants consisted of 110 undergraduate students enrolled in core psychology courses at Fort Hays State University. A web application was created to conduct this specific study that will be made available to other researchers. Significant effects existed for time and goal deficit variables that predicted risk preferences.


Exploring Sex Differences In Morphine Withdrawal-Induced Alterations Of The Ventral Tegmental Area, Samara Morris Bobzean May 2016

Exploring Sex Differences In Morphine Withdrawal-Induced Alterations Of The Ventral Tegmental Area, Samara Morris Bobzean

Psychology Dissertations - Archive

Opioid withdrawal syndrome is a feature common to chronic opioid use that often serves as a powerful motivator of continued drug use. GABA-ergic neurons in the tail of the ventral tegmental area (tVTA) are implicated in mediating responses to opioids and opioid withdrawal. The tVTA regulates the effects of opioids on VTA dopamine neurons and a number of earlier studies have shown that alterations in levels of CREB within the tVTA profoundly affect drug-motivated behaviors. Unfortunately, the mechanisms underlying morphine withdrawal have been studied almost exclusively using men and male animals. The objectives of the current study are to investigate …


Fundamental Image Theory: An Integrated Model Of Trauma, Cassandra K. Sieg May 2016

Fundamental Image Theory: An Integrated Model Of Trauma, Cassandra K. Sieg

Doctor of Psychology (PsyD)

Historically, trauma theory and intervention has focused on “actual or threatened death or serious injury” (DSM-IV; APA, 1994). More recently, the field has broadened its consideration to a range of trauma and stressor related disorders, including perpetration induced traumautic stress (PITS; MacNair, 2015). Violence perpetration has negative implications on a personal, interpersonal, and group level, but a review of the literature reveals a significant gap in our understanding of perpetration-induced traumatic stress, including 2 fundamental questions: how does perpetrating violence cause trauma, and how can we treat this trauma? None of the existing psychological models adequately answer the first question, …


Impact Of Universal Social-Emotional And Behavioral Screening Among Middle School Students: A Multistage Approach To Identification, Kristen M. Ballinger May 2016

Impact Of Universal Social-Emotional And Behavioral Screening Among Middle School Students: A Multistage Approach To Identification, Kristen M. Ballinger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mental health problems often have an onset during the school age years and significantly impact the development, academic achievement, and future success of children and adolescents (Kessler et al., 2005). Less than half of the 10% to 20% of youth believed to be emotionally and behaviorally at-risk receive the mental health services they need (Bradshaw et al., 2008; Gresham, 2007). As a result, universal screening for mental health risk has been recommended as the best initial step to identifying and intervening with at-risk students. Numerous screeners and methods of implementation exist, but a widely accepted and utilized process has failed …


The Development Of Sexual Attitudes In The Family Of Origin And Sexual Satisfaction Later In Life, Bryant Christlieb May 2016

The Development Of Sexual Attitudes In The Family Of Origin And Sexual Satisfaction Later In Life, Bryant Christlieb

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to determine if variance for individuals’ sexual satisfaction as well as attitudes toward sexual instrumentality, sexual permissiveness, sexual communion and attitudes could be predicted by family sexual communication during adolescence as well as various demographic factors such as age, years together, gender, race, income level, religion, religiosity and sexual orientation. This was done by recruiting 250 people via Mechanical Turk (www.mturk.com) and through undergraduate courses at the University of Nevada-Las Vegas. The researcher used an enter-method multiple regression model and Kendall’s Tau for non-parametric data. The results of this study show that sexual satisfaction …


Investigating Inner Experience While Reading An Erotic Short Story, Leiszle Rae Lapping-Carr May 2016

Investigating Inner Experience While Reading An Erotic Short Story, Leiszle Rae Lapping-Carr

UNLV Theses, Dissertations, Professional Papers, and Capstones

An investigation of the phenomenological aspects of sexual response is needed for a more comprehensive understanding of human sexuality. To obtain high fidelity descriptions of inner experience during a sexually oriented task, the current study used Descriptive Experience Sampling (DES) while seven participants read an erotic short story. Participants were trained in DES by sampling during everyday activities. After training, they were sampled while reading two classic short stories on a web-based program. Participants then sampled their experience while reading an erotic short story using the same web-based program. Some of the participants were willing to discuss their inner experience …


The Concordance Of Caregiver-Teacher Perspectives On The Behavior Of Children With Fetal Alcohol Spectrum Disorders, Allison Werlinger May 2016

The Concordance Of Caregiver-Teacher Perspectives On The Behavior Of Children With Fetal Alcohol Spectrum Disorders, Allison Werlinger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diagnosing a child with a Fetal Alcohol Spectrum Disorder (FASD) is a complex process that can require the collaboration of many individuals. Gathering information from multiple informants has been essential for diagnosis (CDC, 2012). The Achenbach Child Behavior Checklist (CBCL) and Teacher Rating Form (TRF) have been used in research to determine cross-informant agreement within various clinical populations, but little research has studied the concordance of caregiver-teacher perceptions on the behavior of children with FASDs. Data from 139 participants diagnosed with an FASD through the Fetal Alcohol Syndrome Clinic in Las Vegas, Nevada were included for analysis. Interrater Pearson r …


Tired, Hungry, And Grumpy: Understanding The Direct And Indirect Relationships Among Child Temperament, Sleep Problems, Feeding Styles, And Weight Outcomes, Alyssa Lundahl May 2016

Tired, Hungry, And Grumpy: Understanding The Direct And Indirect Relationships Among Child Temperament, Sleep Problems, Feeding Styles, And Weight Outcomes, Alyssa Lundahl

Department of Psychology: Dissertations, Theses, and Student Research

Research indicates that temperament is related to later obesity risk in both childhood and adulthood (e.g., Anzman-Frasca et al., 2012; Darlington & Wright, 2006), but less research has examined the mechanisms underlying this relationship. It is likely that temperament influences factors that increase one’s risk for obesity, such as parental feeding practices and child sleep problems. As such, the primary aim of the present study was to provide rigorous concurrent and longitudinal examinations of temperament, feeding practices, sleep problems, and child zBMI in a sample of healthy preschool children. In addition, the moderating role of SES was examined. A secondary …


What Influences Dolphin Interest In Video?, Kelley Ann Winship May 2016

What Influences Dolphin Interest In Video?, Kelley Ann Winship

Dissertations

Environmental enrichment is an important component in maintaining the welfare of animals housed in human care. While a variety of enrichment types (e.g., objects, food, sound) have been utilized, a major challenge in developing enrichment is determining the enrichment potential of various techniques for individual animals. In this study, the efficacy of video clips as enrichment devices was assessed in two species of captive dolphins, exposed to video footage accompanied by sound. Videos were evenly divided into five categories, based on content, and played at underwater viewing windows across 20 sessions while the animals were housed with conspecifics. Species and …


Zephyr: A Social Psychology-Based Mobile Application For Long-Distance Romantic Partners, Dhiraj Bodicherla May 2016

Zephyr: A Social Psychology-Based Mobile Application For Long-Distance Romantic Partners, Dhiraj Bodicherla

Open Access Theses

Long-distance romantic relationships have become quite common nowadays. With CMC tools advancing day-by-day, their usage among LDRs is proliferating rapidly. Attachment-related anxiety and avoidance can block the ability to enjoy happy relationships. During such situations, remembering happy past moments can be comforting. In this study a mobile chat application that enables LDR couples to reminisce about happy moments was developed. This study primarily focuses on evaluating the usability of this mobile application using survey-based methods. System Usability Scale was considered to discuss the outcome of the study. The overall results provide useful recommendations for further improvements in the design of …


Effects Of Optogenetic Activation And Pharmacological Modulation Of Dopamine Neurons, Remington J. Rice May 2016

Effects Of Optogenetic Activation And Pharmacological Modulation Of Dopamine Neurons, Remington J. Rice

All NMU Master's Theses

This study explored the use of optogenetic tools to better understand treatments used for schizophrenia. The “positive” symptoms (e.g., hallucinations, paranoia, etc.) of schizophrenia may come from overexpression of dopamine in mesolimbic dopamine neurons. Positive symptoms can be produced in healthy volunteers treated with amphetamine, a psychostimulant drug and dopamine releaser. Conversely, antipsychotic drugs may reduce positive symptoms by blocking dopamine receptors. This study used optogenetics to explore how drugs that alter neurotransmission, might alter behaviors occurring from activation of mesolimbic dopamine (DA) neurons in the ventral tegmental area (VTA). Light-induced activation of DA neurons in the VTA in male …

Authoritative Parenting And Transformational Leadership: An Example Of Family-To-Work Enrichment, Katherine Kearns

Masters Theses and Doctoral Dissertations

The present study was designed to examine the relationship between authoritative parenting and transformational leadership as an example of family-work enrichment. Participants were working managers who are parents (N = 150), recruited from MBA programs, manufacturing companies, and social media. Participants responded to an internet-based survey composed of measures of parenting style, work-family enrichment, and transformational leadership. Participants also provided responses regarding the overall impact of having children on their personal leadership development. Analyses of self-reported data consisted of correlation and regression-based methods for identifying relationships and predictor variables. Qualitative data were also gathered and content analyzed, helping to illustrate …


Anticipated Work-Nonwork Balance And Conflict As Predictors Of Job Choice: Identity Salience As Moderator, Christopher R. Hudson Jr. May 2016

Anticipated Work-Nonwork Balance And Conflict As Predictors Of Job Choice: Identity Salience As Moderator, Christopher R. Hudson Jr.

Masters Theses and Doctoral Dissertations

This study examines individual job choice decision making with the foreknowledge that such choices will impact the quality of a person’s future work-nonwork roles. It is likely that job applicants have at least some anticipation of the work-nonwork conflict (WNC) and work-nonwork balance (WNB) they will face if they accept a certain job offer. Although most research has provided reasons for organizations to promote WNB and reduce WNC in the workplace, little research has examined the influence of anticipated WNB and WNC on applicant job choice. The present study explores this question and considers whether a person’s work and nonwork …


Scared To Death: An Examination Of Underlying Terror Following Death Awareness, Robert B. Arrowood May 2016

Scared To Death: An Examination Of Underlying Terror Following Death Awareness, Robert B. Arrowood

Masters Theses and Doctoral Dissertations

According to Terror Management Theory, when mortality is made salient the potential to experience terror causes powerful worldview defenses to manifest to suppress this potential. Recently, however, the theory has been criticized because no actual evidence has been found to show this potential to experience terror. The current research used Galvanic Skin Response and a battery of self-report measures (e.g. negative affect, stress, fear, distress, etc.) to attempt to provide evidence of potential terror. The results were partially confirmatory suggesting that although mortality salience failed to evoke arousal, negative affect, and stress, it did evoke sadness and distress and suggests …


Psychotherapy Dropout : The Influence Of Ethnic Identity And Stigma On Early Termination., Le'keldric Jawon Thomas May 2016

Psychotherapy Dropout : The Influence Of Ethnic Identity And Stigma On Early Termination., Le'keldric Jawon Thomas

Electronic Theses and Dissertations

Although clients continue to drop out of psychotherapy, researchers have made few inroads into understanding the dropout phenomenon. Clinical studies have reported client dropout rates based on demographic factors (e.g., race, socioeconomic status, educational status). However, few studies have investigated the cultural correlates that may underlie these demographic factors and affect client termination. Furthermore, none have provided an empirically driven explanation as to why some clients drop out more often than others. In two studies, I explore dropout in two settings: a community mental health center and a university counseling center. Guided by current theory and research, I will examine …


Spirituality And Psychological Well-Being Among Als Caregivers: Hope And Perceived Stress As Mediators, Bridget R. Jeter May 2016

Spirituality And Psychological Well-Being Among Als Caregivers: Hope And Perceived Stress As Mediators, Bridget R. Jeter

Electronic Theses and Dissertations

The empirical study of the salutary relationship between spirituality/religiousness and psychological well-being is burgeoning. However, mechanisms of this association have received less empirical attention. Theory suggests that spirituality/religiousness may lead to positive psychological characteristics such as hope, which may function as a means of coping in the context of a significant stressor or stressful situation. The perceived burden and stress associated with caring for individuals with chronic illnesses such as ALS is significant, and caregivers may be at risk for increased symptoms of depression, symptoms of anxiety, somatic symptoms, and other deleterious psychological well-being related outcomes. Within the context of …


Attention-Deficit/Hyperactivity Disorder Symptoms As A Mediator Of The Relation Between Social Perception And Social Skills And Adaptability In Preschoolers, Brandi Michelle Ellis May 2016

Attention-Deficit/Hyperactivity Disorder Symptoms As A Mediator Of The Relation Between Social Perception And Social Skills And Adaptability In Preschoolers, Brandi Michelle Ellis

Master's Theses

ADHD symptoms have been linked empirically to both social perception deficits as well as impairments in social skills and adaptability. The current study built on existing literature by examining whether social perception abilities indirectly predicted social skills and adaptability through ADHD symptoms in preschool-aged children. The sample consisted of 3- to 6-year-old children attending Head Start Programs and private preschools (N = 76). It was expected that social perception abilities would positively relate to both social skills and adaptability. It was also expected that these relations would occur indirectly through ADHD symptoms. Specifically, social perception abilities would relate negatively …


Social Interactions Among Two Males In A Captive Group Of Rough-Toothed Dolphins (Steno Bredanesis), Pepper Reid Hanna May 2016

Social Interactions Among Two Males In A Captive Group Of Rough-Toothed Dolphins (Steno Bredanesis), Pepper Reid Hanna

Master's Theses

There is relatively little known about the social behavior of rough-toothed dolphins (Steno bredanensis) particularly in comparison to information on the Atlantic bottlenose dolphin, (Tursiops truncates). The purpose of the current study is to describe the social behavior of two juvenile male rough-toothed dolphins housed at Gulf World Marine Park in Panama City Beach, FL. Rates of affiliative social behaviors were greater between the two males within this group compared to the other pairs of dolphins. The males exhibited a high rate of association, calculated using the half-weight index. Following aggressive behavior within the overall group, the …


Does 'Fear Of Dying' Indicate A More Severe Presentation Of Panic Disorder?, D. Gazarian, M. D. Multach, William D. Ellison, Iwona Chelminski, Kristy Dalrymple, Mark Zimmerman May 2016

Does 'Fear Of Dying' Indicate A More Severe Presentation Of Panic Disorder?, D. Gazarian, M. D. Multach, William D. Ellison, Iwona Chelminski, Kristy Dalrymple, Mark Zimmerman

Psychology Faculty Research

Research suggests a relationship between the presence of fearful cognitions and panic disorder (PD) severity. With little existing evidence addressing the clinical significance of individual panic-cognitions, the current study examined presentation and impairment differences among 331 outpatients with PD according to whether they experience “fear of dying” (FOD) during panic attacks. Patients reporting FOD (n = 153) were compared to patients denying FOD (n = 178) on variables indicating PD severity (e.g., number of symptoms) and psychiatric impairment (e.g., hospitalizations). PD patients with FOD reported a greater number of panic symptoms, agoraphobia diagnoses, and were more likely to be seeking …


Trauma And Touch: Apprehension Of Touch And Relationship Quality In Survivors Of Military Sexual Trauma, Danielle Christensen May 2016

Trauma And Touch: Apprehension Of Touch And Relationship Quality In Survivors Of Military Sexual Trauma, Danielle Christensen

Undergraduate Honors Capstone Projects

Sexual assault is linked to poor romantic relationships but sexual assault in the military is linked to more severe outcomes than civilian assault (Surís et al., 2007).One in four women Veterans report military sexual trauma (MST; VA, nd). MST is highly correlated with Post-Traumatic Stress Disorder and lower relationship satisfaction, which is problematic as relationship quality buffers against PTSD and dysfunction secondary to MST. Relationship quality is multidimensional and includes satisfaction with physical touch; the effects of sexual trauma on touch apprehension have not been examined in those with MST. Moreover, it is not clear whether contact MST (e.g., rape) …


The Lipstick Effect Operates At The Level Of Automatic Visual Attention, Aaron M. Bermond May 2016

The Lipstick Effect Operates At The Level Of Automatic Visual Attention, Aaron M. Bermond

Honors Theses

Although general consumer spending usually decreases during economic recessions, Hill and colleagues (2012) found evidence that women concerned with economic recession demonstrated an increased preference towards purchasing products capable of enhancing physical beauty, thereby allowing them to appear more attractive to mates with resources. Referring to this phenomenon as the lipstick effect, these researchers suggested such purchasing preferences demonstrate evidence for an evolved female mating strategy. The current study was designed to more directly test whether the lipstick effect represents an evolved female mating adaptation by determining if it operates at the level of automaticity, specifically automatic visual attention (Fodor, …


Socialization Of Respeto In Immigrant Mexican Families, Marsha Tafoya May 2016

Socialization Of Respeto In Immigrant Mexican Families, Marsha Tafoya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Respeto is a cultural value considered to be essential in Latina/o families. Latina/o parents endorse respeto as being an important to teaching to their children. Mental health professionals argue that it is important to understand cultural values in delivering appropriate and relevant services to ethnic and culturally diverse clients. Some experts argue that such focus on cultural context also improves the effectiveness of interventions. The current study examined the cultural value of respeto in immigrant Mexican parents with a child between 4 and 9 years of age. Two scales were developed to examine the behavioral displays of respeto in boys …


Examining The Effects Of Caregiver Coping Strategies On Care Recipient Outcomes, Joseph S. Wanzek May 2016

Examining The Effects Of Caregiver Coping Strategies On Care Recipient Outcomes, Joseph S. Wanzek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dementia is a progressive syndrome with declines in cognitive and functional abilities. As the world’s population becomes increasingly older, prevalence rates are expected to increase exponentially to over 80 million affected by the year 2040. Individuals with dementia and their caregivers experience various difficulties associated with progression that increases stress for both parties. Caregiving can be burdensome and caregivers may employ a number of strategies to manage problems as they arise. Renewed interest has been focused on the care environment as one way to modify dementia progression as caregivers can be an influential person in the care recipient’s life. Two …


The Effects Of Familism And Sibling Relationships On Mexican-Origin Adolescents' Intentions For Alcohol, Tobacco, And Other Drug Use, Molly Mechammil May 2016

The Effects Of Familism And Sibling Relationships On Mexican-Origin Adolescents' Intentions For Alcohol, Tobacco, And Other Drug Use, Molly Mechammil

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The aim of this study was to investigate whether and how sibling relationships and family values intersect to influence Mexican origin youth’s intentions to use substances. Previous research with European-American families has indicated that the nature and quality of sibling relationships in particular plays a large role in whether or not youth will engage in substance use behaviors. In addition, high levels of family and cultural values have also been found to be strong protective factors for substance use in Latino youth. A better understanding of the relation between family values and sibling relationship processes is important in order to …


The Effect Of Weight On The Perceptions Of And Attitudes Toward Individuals With Anorexia Nervosa, Allison E. White May 2016

The Effect Of Weight On The Perceptions Of And Attitudes Toward Individuals With Anorexia Nervosa, Allison E. White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A large body of research has shown that stigmatizing attitudes toward individuals with mental illness are widespread and prevalent. Fewer studies have focused on stigma toward eating disorders, in general, and even less have focused on the stigma of anorexia nervosa (AN), specifically. Preliminary research indicates that AN may be both stigmatizing and admired, but the factors contributing to the perception of AN has not been adequately studied. To date, researchers have yet to examine the role of body size in the perception of and attitudes toward individuals with AN. By showing participants one of three female figures varying only …


Treating Chronic Pain At A Federally Qualified Health Center: Staff Perspectives, Nathan K. Goins May 2016

Treating Chronic Pain At A Federally Qualified Health Center: Staff Perspectives, Nathan K. Goins

Doctor of Psychology (PsyD)

Although half of all patients with chronic pain seek treatment with their primary care practitioner, many physicians report being overburdened, with limited confidence in their training in the treatment of chronic pain. Opiate monotherapy remains the most common treatment utilized, despite strong correlations with addiction issues and increased distrust between patients and providers. In response to these issues, multidisciplinary stepped-care approaches utilizing psychoeducation, cognitive therapies, movement-based therapy, pharmaceutical treatment, yoga, and acupuncture have been developed. However, treatment within Federally Qualified Health Centers (FQHC) are complicated by financial constraints and high complexity in patient populations. This study examined the perspectives of …


The Benefits Of Shifting From A Punitive Justice System To One That Is Mental Health Aware, Sarah Flatin May 2016

The Benefits Of Shifting From A Punitive Justice System To One That Is Mental Health Aware, Sarah Flatin

Honors College Theses

Since the 1950’s there has been an increasingly large population of individuals suffering from psychological disorders within the United States criminal justice system. Many psychiatrists and psychologists attribute this rising population to deinstitutionalization, a period in which psychiatric hospitals drastically reduced the number of patients they would serve. As a result, a larger amount of persons suffering from psychological disorders were released into society, where their symptoms are sometimes misinterpreted and criminalized, thus involving the criminal justice system. In response to this growing population the criminal justice system has begun to implement several methods for handling individuals suffering from psychological …


Influences Of Temperament, Symbolic Gesture, And Caregiver Beliefs On Infant Emotional Expression, Mary Sugg Bassett May 2016

Influences Of Temperament, Symbolic Gesture, And Caregiver Beliefs On Infant Emotional Expression, Mary Sugg Bassett

Graduate Theses and Dissertations

The purpose of the cross-sectional study was to analyze the relationships of infant temperament, communication through symbolic gesture, caregiver beliefs with emotional expression in infants. Participants were the parents and childcare teachers of sixteen infants and toddlers, between the ages of six and 25 months, currently enrolled at the University of Arkansas child development study center. The independent and combined influence of infant temperament, use of symbolic gestures, and the beliefs of parents and teachers were significantly related to infants’ emotional expression in the study. Parent-reported scores of emotional expression competence were positively correlated to teacher-reported positive temperament levels (r …


The Role Of Child Anxiety In Parent Sick Role Reinforcement, Sarah Ann Bilsky May 2016

The Role Of Child Anxiety In Parent Sick Role Reinforcement, Sarah Ann Bilsky

Graduate Theses and Dissertations

A large body of evidence suggests that parents can facilitate offspring anxiety in response to bodily arousal. These learning experiences are referred to as “sick role reinforcement,” and are particularly important during adolescence, given the profound bodily changes (e.g., puberty) that characterize this period. Sick role reinforcement is likely important in the context of panic disorder (PD). Panic theorists suggest that parents may enhance panic vulnerability by increasing the threat value of bodily sensations. Although a sizeable body of work has examined the role of parent behavior in these processes, few have examined offspring factors in this process. Additionally, little …


African American Female Offender's Use Of Alternative And Traditional Health Services After Re-Entry: Examining The Behavioral Model For Vulnerable Populations, Carrie B. Oser, Amanda M. Bunting, Erin L. Pullen, Danelle Stevens-Watkins May 2016

African American Female Offender's Use Of Alternative And Traditional Health Services After Re-Entry: Examining The Behavioral Model For Vulnerable Populations, Carrie B. Oser, Amanda M. Bunting, Erin L. Pullen, Danelle Stevens-Watkins

Sociology Faculty Publications

This is the first known study to use the Gelberg-Andersen Behavioral Model for Vulnerable Populations to predict African American women's use of three types of health services (alternative, hospitalization, and ambulatory) in the 18 months after release from prison. In the multivariate models, the most robust predictors of all three types of service utilization were in the vulnerable theoretical domains. Alternative health services were predicted by ethnic community membership, higher religiosity, and HIV/HCV. Hospitalizations were predicted by the lack of barriers to health care and disability. Ambulatory office visits were predicted by more experiences of gendered racism, a greater number …
