Borderline Personality Disorder And Self-Conscious Emotions In Response To Adult Unwanted Sexual Experiences, Michelle Schoenleber, Kim L. Gratz, Terri Messman-Moore, David Dilillo

Department of Psychology: Faculty Publications

Borderline personality disorder (BPD) is associated with a proneness to unpleasant self-conscious emotions (SCE). Given that BPD is also associated with heightened rates of SCE-eliciting events (including unwanted sexual experiences), research examining the factors influencing SCE in response to these events is needed. This study examined associations between BPD pathology and SCE in response to adult unwanted sexual experiences among 303 community women. Extent of sharing about and perceived personal responsibility for the event were examined as moderators of the association between BPD and current event-related SCE. Both self-reported BPD symptom severity in the full sample and interview-based measures of …

Predicting Science Literacy And Science Appreciation, Robert Hellmuth

HIM 1990-2015

Research has shown that the benefits of having a populace literate in science are great. Even if citizens are not literate in basic science, it is important that citizens still appreciate science and those with expertise in the field for many reasons. Recent research suggests that the United States (U.S.) has lower levels of science literacy than it should. Evidence may also suggest that many U.S. citizens are not appreciative of science. Overall, little research has been conducted on what may predict science literacy and science appreciation which is the aim of this research. Specifically, I have examined socio-personal variables, …

Media Influence On Risky Driving Behaviors Among Adolescents And Emerging Adults, Kelly Silberman

HIM 1990-2015

Within the last few decades there has been an abundant increase in the amount of violent video games and movies shown within the media. Many of these violent videogames and movies include reckless driving behaviors or certain car scenarios that engross the viewer into wishing to imitate the actions they see on the screen. With that being said, majority of these viewers are adolescents or emerging adults who are beginning to drive and are prone to replicating what they see as adequate driving behaviors. The intent of this thesis is to indicate whether or not the amount of risky driving …

Issues Of Social Data Analytics With A New Method For Sentiment Analysis Of Social Media Data, Zhaoxia Wang, Victor J. C. Tong, David Chan

Research Collection School of Social Sciences

Social media data consists of feedback, critiques and other comments that are posted online by internet users. Collectively, these comments may reflect sentiments that are sometimes not captured in traditional data collection methods such as administering a survey questionnaire. Thus, social media data offers a rich source of information, which can be adequately analyzed and understood. In this paper, we survey the extant research literature on sentiment analysis and discuss various limitations of the existing analytical methods. A major limitation in the large majority of existing research is the exclusive focus on social media data in the English language. There …

Oppositional And Anxiety Behavior Profiles In A Clinical Sample Of Youth With Selective Mutism, Rachele Diliberto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children with selective mutism often present as a very heterogeneous population, with both anxious (APA, 2000; 2013; Kristensen 2000; Manassis et al., 2007; Steinhausen & Juzi, 1996; Yeganeh et al., 2003) and oppositional symptoms (APA, 2013; Andersson & Thomsen, 1998; Kolvin & Fundudis, 1981; Krohn, Weckstein, & Wright, 1992). This study sought to identify anxiety and oppositional behavior profiles in a clinical sample of children with selective mutism. Also, this study sought to determine both discriminant and concurrent validity for these profiles and examine their association with family expressiveness, conflict and control. Participants (n=57) included youth receiving treatment at the …

Exploring The Inner Experience Of Veterans With Posttraumatic Stress Disorder, Stacy Reger

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of psychology contains a vast literature describing and attempting to understand Posttraumatic Stress Disorder (PTSD) and its detrimental effects on the lives of individuals with the disorder. Despite the volume of study dedicated to PTSD in the literature, in-depth accounts of the lived experience of individuals with PTSD are rare. The current study utilized Descriptive Experience Sampling (DES), a method based on apprehending high-fidelity accounts of momentary inner experience, to explore the inner experience of eight Operation Iraqi Freedom …

The Relationship Between Racial Ambiguity And Self-Concept In Multiracial Lndividuals, James R. Jobe

Dissertations

The present study examined the relationship between racial ambiguity and self-concept in multiracial individuals. Research as to the experiences of multiracial people is limited both in frequency and in scope. As multiracial individuals continue to grow in number, understanding their unique experiences will become more important to social scientists (e.g., psychologists, anthropologists, sociologists) across disciplines. The current study examined two hypotheses and explored a series of additional relationships. The theoretical framework that was utilized for this study was Symbolic Interaction Theory. This theory provided an effective way to understand how people use and make meaning of their surrounding social contexts …

The Neurobehavioral Consequences Of Gestational And Chronic Atrazine Exposure In Male And Female Sprague Dawley Rats, Jennifer L. Walters

Dissertations

The adverse health risks of exposure to the herbicide, atrazine, in humans are not fully understood. Although numerous studies have demonstrated atrazine to be an endocrine disrupter, the neurobehavioral consequences of atrazine exposure have not been thoroughly examined. The aim of this study was to investigate the effects of environmentally-relevant levels

of gestational followed by continued chronic atrazine exposure on motor function, learning and memory, anxiety, and striatal dopamine content in rodents. Pregnant Sprague Dawley rats were treated by gavage with 100 µg/kg atrazine (ATZ low), 10 me/kg atrazine (ATZ high), or vehicle on

Evaluation Of Novel Κappa Opioid Agonists Alone And In Combination With D-Amphetamine On Locomotor Activity In Sprague-Dawley Rats Evaluation Of Novel Κappa Opioid Agonists Alone And In Combination With D-Amphetamine On Locomotor Activity In Sprague-Dawley Rats, Mary Melissa Peet

Dissertations

Stimulant abuse is a widespread problem that often leads to detrimental health and social consequences. Currently, there are no FDA-approved pharmacotherapies available as a treatment option for stimulant abuse or the prevention of relapse. Drugs targeting kappa opioid receptors (KOR) are under investigation as a potential pharmacotherapy. KOR agonists have been shown to modulate dopamine levels within brain reward pathways, thereby producing anti-addictive effects. Traditional KOR agonists unfortunately tend to produce untoward side effects, including sedation, limiting their therapeutic utility. Structurally different from traditional KOR agonists, salvinorin A (salvA) may produce less sedating effects while still exerting anti-addictive properties. SalvA …

The Effect Of Grapes In Mice With Alzheimer's Disease And Brain Injury, Nikita Mistry

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder resulting in cognitive and memory deficits and deposits of amyloid beta (Aβ) in the cortex and hippocampus are thought to be significant contributors to the disease process. Increasing evidence suggests that foods rich in polyphenols, such as pomegranates and grapes, may have neuroprotective effects in both rodents and humans. Our previous research has shown that a pomegranate-enriched diet decreased Aβ plaque load and improved behavior in Tg2576 mice. In this study, we determined whether a grape-enriched diet altered Aβ neuropathology and TBI in PSAPP mice. Mice received either craniotomy or a moderate …

Risk Factors For Substance Use In The American Indian/Alaska Native Community, Kelli Lewis Rugless

Loma Linda University Electronic Theses, Dissertations & Projects

Research has indicated that substance use is a significant problem in the American Indian/Alaska Native adolescent community. What is less understood are the risk and protective factors specific to this community. Using data available from the Communities That Care Youth Survey, we analyzed risk and protective factors for current (30-day) and lifetime use of smokeless tobacco, cigarettes, alcohol, marijuana, and alcohol in a sample of 5,912 AI/AN adolescents. Logistic regression analyses were used and our findings indicated that peer and family influences, as well as ease of access to alcohol and other drugs had the greatest overall impact on AI/AN …

Who Or What Should I Be Like? The Self-Assessment Of Sexual Desire, Caroline Maykut

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construct of sexual desire has been notoriously difficult to capture and measure, in part as a function of questionable methods of sexual desire assessment. Due to problems finding an accurate, objective marker of sexual desire, research has relied on self-report. One notable difficulty with self-reported desire assessment is the lack of information on the context in which these assessments are made. The only available data focuses on relative assessment of sexual desire within couples, and ignores broader social and cultural contexts. The present study investigated men and women's perception of sexual desire discrepancies between themselves and other people and …

The Presentation Of Childhood Parental Divorce In Adulthood: A Retrospective Phenomenological Study, Sheala Catherine Morrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has been a wealth of research aimed at developing an understanding of the way in which the experience of divorce impacts children. However, adult children of divorce have been widely underrepresented in this literature, much of which is outdated being at least ten years old. With shifting societal attitudes and the transformation of the family system since the 1990's it is crucial that the research is updated in order to stay up on the way children and families are impacted in today's society. The purpose of this study was to hear directly from adults who experienced their parents' divorce …

Mystical Experience As Predictor Of Domains Of Religious And Spiritual Self Identification: Empirical And Theoretical Considerations, Sara E. Hall-Mckane

Masters Theses and Doctoral Dissertations

The concept of spirituality has emerged as a major focal point in both the theoretical and empirical study of religion. Whether the emergence of spirituality is a dimension of religion or a separate and distinct construct has been the subject of much debate among scholars. The philosophical arguments proposed on either side have underscored the need for further research into just what spirituality is and is not. An ongoing transition from a more religious to a more spiritual self identification is evident at least in the United States (Roof & Greer, 1993, 1999; Pargament, 1999). Using the data collected from …

The Effects Of Language Complexity On Natural And Emotion Concept Formation In Early Language Learners, Stephanie Eileen Jett

Dissertations

The present study investigated the role of language complexity in natural and emotion concept formation ability in young children (two- to five-year-olds). Language complexity was measured by selections from the Brigance Diagnostic Inventory of Early Childhood Development II, and concept formation was assessed at three levels of abstraction. The natural concepts were presented as two alternative discriminations on a touch-screen computer, as follows: subordinate level (lions versus tigers), basic level (cats versus dogs), and superordinate level (animals versus nonanimals). The following emotion categories were discriminated: subordinate level (anger versus sadness), basic level (positive [happiness and positive surprise] versus negative [anger …

Does Video Game Use Exacerbate The Relation Between Neurophysiological Deficits And Adhd Symptoms In Children And Adolescents?, James Kenneth Goodlad Iii

Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is diagnosed based on behavioral symptoms but is thought to have a significant heritable neurological basis, and several brain structures have been implicated. Recent research has focused on the role of environmental factors that may influence the behavioral expression of inattention and hyperactivity-impulsivity in children and teens, particularly when a biological predisposition exists. This study sought to broaden the literature base by examining the extent to which one environmental factor—video game use—moderated the relation between neuropsychological deficits in attention and inhibition and the behavioral symptoms of ADHD. It was hypothesized that gaming frequency and duration as well …

The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

The (Un) Desirability Of Happiness: Pathogen Threats Predict Differences In The Value Of Happiness, Sharon Li Hua Koh

Dissertations and Theses Collection (Open Access)

People in some parts of the world find positive emotions more desirable than others. What accounts for this variability? We predicted that happiness would be valued less under conditions where the behaviors that happiness promotes would be less beneficial. We analyzed international survey data and United Nations voting records and found that happiness was valued relatively less in environments that had been historically pathogen-rich. Using a series of experimental studies, we showed that people who were experimentally primed by the threat of pathogens judged happiness in others less favorably and found happiness less appropriate. Our findings contribute to research on …

Effects Of Oxytocin On Human Aggression, Joseph L. Alcorn Iii

Dissertations and Theses (Open Access)

EFFECTS OF OXYTOCIN ON HUMAN AGGRESSION

Joseph Louis Alcorn III, B.S.

Advisory Professor: Scott D. Lane, Ph.D.

Human interaction is comprised of common, yet complex, behaviors and the outcomes of these social behaviors can beneficially or detrimentally impact individual and public health. One social behavior that can have profound detrimental outcomes is aggression. Aggression is a class of social behavior that is particularly prevalent in individuals with antisocial personality disorder (ASPD) and comorbid substance use disorder (SUD). Aggression in these individuals can manifest at maladaptive levels that place considerable burdens on public health and communities. Therefore, understanding the neurobehavioral underpinnings …

Do I Have Enough Money? An Examination Of The Roles Of Income And Income Perceptions On Nursing Turnover Intentions, Janelle Cheung

All Theses

Economic stress is an understudied, but potentially critical, concern that deserves more attention in the literature because it has important implications for employees and organizations. The present study sought to bring researchers and practitioners' attention to this area of research by examining the impact of income and income perceptions on turnover intentions. Very few published studies have investigated the mechanisms underlying the relationship between income and turnover intentions. As a novel contribution, the present study examined how perceived adequacy of current and future income each and simultaneously mediated the relationship between income and turnover intentions.

Consumer Acceptance And Willingness To Pay For Genetically Modified Rice In China: A Double Bounded Dichotomous Choic Contingent Valuation Survey Calibrated By Cheap Talk, Jing Jin

Graduate Theses and Dissertations

Considering population growth, limitations on land and water resources, and contamination to the ecosystem due to agricultural activities, current rice production in China is facing pressure to fulfill national demand. Self-sufficiency of rice has been a long-held political objective of the Chinese government and it is national goal to maintain the equilibrium between the national production and consumption or even achieve a supply surplus in rice. With the developing bio-technology of genetic modification (GM), scientists believe that using genetically modified cultivars may ease the pressure mentioned above. However, both the government and the people are very cautious about large-scale cultivation …

Human Behavior During Spaceflight: Evidence From An Analog Environment, Kenny Mikael Arnaldi

Doctoral Dissertations and Master's Theses

Spaceflight offers a multitude of stressors to humans living and working in space, originating from the external space environment and the life-support system. Future space participants may be ordinary people with different medical and psychosocial backgrounds who may not receive the intense spaceflight preparation of astronauts. Consequently, during a mission, a space participant’s mood and behavior could differ from a trained astronaut. This study was an exploratory research project that used an artificial habitat to replicate an orbital environment and the activities performed by humans in space. The study evaluated whether the type of environment affects mood and temperament. Two …

Impulsivity, Venturesomeness, And Pride: Potential Moderators Of The Relationship Between Childhood Trauma, Substance Use, And Physical Aggression, Joshua P. Hatfield

Electronic Theses and Dissertations

Impulsivity, venturesomeness, and pride variables were examined as potential moderators of the associations between childhood trauma and physical aggression, alcohol use and physical aggression, and drug use and physical aggression. Participants (n = 457) were college students recruited from a university in the Southeast. It was hypothesized that childhood trauma, alcohol use, and drug use would be associated with increased scores of physical aggression. In addition, it was hypothesized that impulsivity, venturesomeness, authentic pride, and hubristic pride would moderate these relationships. Linear, multivariate hierarchical regression analyses were used to examine these variables as potential moderators. Hypotheses concerning hubristic pride as …

Possible Benefits Of Playing Music Video Games, Amanda Pasinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music video games, such as Rock Band, are an emerging and popular genre of video game that allows non-musicians a taste of what it is like to be a musician. For most people, developing musicianship (or the process of becoming competent with a particular musical instrument) to an expert level is a long and difficult process that can take up to 10 years or over 7,500 hours to complete. Yet musicians tend to outperform non-musicians on a variety of tasks--showing greater motor coordination, better synchronization skills, and better pitch and tempo discrimination--and possibly show differences in related cognitive processes. However, …

Client Selected Music Based Effects On Marital And Couples Therapy, Kevin Matthew Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study was designed to examine the interaction of music-based interventions in the therapeutic process of Martial and Couples Therapy. The use of pre-recorded music was found to be under researched within the literature and created a void within the knowledge that clinicians have about how music might enhance effectiveness of treatment. The inclusion of music in this process is not currently known, which led to this study being conducted. Through a phenomenological lens, the awareness and understanding of how clients react and experience pre-recorded music during the therapeutic process, while still having a selection of options to preserve autonomy, …

Executive Functioning In The Context Of Urban Poverty: An Examination Of Poverty Related Stress And Its Relationships To Academic Achievement, Jacquelyn L. Doxie

College of Science and Health Theses and Dissertations

Living in urban poverty has been linked to numerous negative conditions that disproportionately expose low-income urban youth and their families to severe and chronic stressors (Collins et al., 2010; DeNavas-Walt, Proctor, and Smith, 2012; Sznitman, Reisel, and Romer, 2011). Research has consistently shown a strong relationship between these stressors and numerous negative outcomes that can impact an adolescent emotionally, behaviorally, and academically (Conger et al., 2002). This dissertation is focused on the area of academic achievement, an outcome consistently found to be negatively impacted by poverty (Rouse and Fantuzzo, 2009). Based on Bronfenbrenner’s model of bio-ecological human development (Bronfenbrenner and …

Dissertations

The current study examined the effects of telecommuting intensity – the amount of scheduled time that employees spend doing work away from the central work location – on employee outcomes. Results of this study provided insight into how telecommuting intensity relates to turnover intent and supervisor-rated performance through mediating mechanisms of work-life conflict, professional isolation, and Leader-Member Exchange. An online survey instrument was created, and an invitation to participate was sent by e-mail to telecommuters. Each participant was asked to provide an email address for his or her direct supervisor. The supervisor was asked to complete a shortened version of …

On Reporting The Onset Of The Intention To Move, Uri Maoz, Liad Mudrik, Ram Rivlin, Ian Ross, Adam Mamelak, Gideon Yaffe

Psychology Faculty Books and Book Chapters

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …
