Social Affiliation: A Model Of Anxious Avoidance In Women, Milena Stoyanova

Department of Psychology: Dissertations, Theses, and Student Research

There is substantial evidence demonstrating that women experience greater anxiety and fear compared to men. However, our understanding of specific factors accounting for women’s greater vulnerability remains rather limited. Taylor and colleagues (2000) proposed that women may have a different biobehavioral response to stress, which has evolved to protect and nurture offspring. The tend-and-befriend model provides new opportunities to explore underlying processes that may contribute to women’s greater anxiety and fear.

The present study examined women’s stress response combined with the absence of positive social contact as it relates to the presentation of fear and anxiety. One hundred and seven …

The Effects Of Music On Anxiety And Depression In Emerging Adults, Kendra Bartel

HIM 1990-2015

The purpose of the current study was to observe how music affects the mood of those who suffer from anxiety and depression and those who do not. While previous research has examined this many of the previous studies have induced either physical pain or mood in participants in order to measure the impact of music. The current study, however, intends to examine how music affects mood without attempting to induce mood in participants. Six-hundred and seventy college students were given a questionnaire containing an anxiety questionnaire, depression scale, demographic questionnaire, and music listening questionnaire. Intercorrelations, ANOVAS, as well as linear …

Effects Of Abortion On College Women's Mental Health, Estefany Bologna

HIM 1990-2015

Since the legalization of abortion, some research studies have argued that abortion has a neutral effect when considering other coexistent factors (e.g. Adler et al., 1990; Major et al., 2000; Steinberg & Russo, 2008). Other studies have concluded that abortion has a negative influence on women's psyche (e.g. Congleton & Calhoun, 1993; Cougle, Reardon, & Coleman, 2005; Hamana et al., 2010). College populations have been generally excluded from abortion research, even though, in 2007, 57% of women obtaining abortions were between the ages of 20 and 30 years (U.S. Census Bureau, 2012). This study intended to measure the influence of …

The Role Of Mentoring On The Development Of Ethnic Identity As It Relates To Body Image Concerns In Ethnic Minority Women, Raven Cokley

HIM 1990-2015

Emerging literature emphasizes the importance of mentoring in the development of minority youth. In particular, mentoring influences the development of youths' sense of self and self-concept. By examining the conceptual frameworks of both mentoring and racial socialization, this study summarizes the theoretical processes associated with youth development and how such development relates to young women's ethnic/racial identity including their body image. The mentoring relationship is examined with a small pool of ethnic-minority, college-aged female participants to explore whether there is a relationship between having received positive mentoring and the participant's current body image perceptions.

Subtypes Of Anhedonia And Facial Electromyography Response To Negative Affective Pictures In Healthy Adults, Lisa Kadison

HIM 1990-2015

Flat affect (i.e., diminished expressivity) and self-reported anhedonia (i.e., lack of pleasure) are associated with many psychiatric disorders. There is a need to examine the relationship between specific anhedonia subtypes and flat affect in a non-clinical sample. Forty-seven undergraduate students (59% male; mean age 20.37; SD = 4.74) completed self-report questionnaires assessing four subtypes of anhedonia - consummatory/anticipatory by social/non-social. Participants then viewed 15 randomly-presented pictures (five neutral, ten negative) from the International Affective Pictures System while facial muscle activity (electromyography; EMG) was recorded. Male participants reporting a greater level of anhedonia, particularly consummatory social anhedonia, showed greater EMG activity …

Childhood Cat Bites And Disorganized Symptoms Of Schizotypy In Adulthood, Jenya Kolpakova

HIM 1990-2015

During recent years of schizophrenia research, many etiologies have been emphasized, some of them implicating infectious and autoimmune diseases. Many different infectious agents have been examined, but the root seems to stem from the secondary autoimmune deregulation, which can be caused by different infectious agents. Among the effects that autoimmune deregulation has on the body, one prominent effect is on the brain, resulting in either severe or mild encephalitis. The mild encephalitis that has been implicated as one of the causes of schizophrenia-spectrum disorders has been associated with different pathogens, many of which can be transmitted by the household cat. …

Exploring Religious Bias And Perceptions Of Atheism, Raina Leckie

HIM 1990-2015

Much research focuses on religious bias and in particular the marginalization of Muslims in America. What initially surprised post 9-11 researchers is that participants typically rank atheists lower than Muslims in the areas of private and public trust. Further research is needed to continue to understand the nature and extent of religious-based bias. The present study explores whether a job candidate's religion impacts perception of the candidate's "hireability" and source credibility, including elements of trustworthiness, expertise and attractiveness. Participants were randomly assigned to review an identical version of a resume in which only the implied religion of the candidate was …

The Effect Of An Auditory Stimulus On Change Blindness, Shane Mccormack

HIM 1990-2015

This research examined whether or not an auditory stimulus would affect rates of change blindness. Change blindness occurs when there is a failure to detect an obvious change to a visual scene. For this experiment 40 participants were asked to determine if a change occurred between two pictures. This involved an original picture shown for 1 second, a neutral screen shown for 50 milliseconds and then either a modified version of the original image or the same image for 1 second and then repeated. Participants then determined whether a change occurred in the visual display. For some participants a familiar …

Profanity's Relation To Personality And Impulsivity, Jasmin Mokbel

HIM 1990-2015

The relationship of swearing in respect to personality, religiosity, and social influences was analyzed in this study. Many assumptions are made about the effects of swear words and the act of swearing can have on an individual. The present study hypothesizes that the use of swears words is dependent on an individual's personality characteristics and that exposure first happens from an external source (mass media outlets) rather than a familiar source (family member). More specifically, extroverted personality types will be more likely to engage in the use of profanity, due to their more impulsive nature. Online surveys such as the …

Stigma Related To Depression: A Comparison Between African American And White Young Adults, Amirica Nicholson

HIM 1990-2015

This study examined the effects of gender, ethnicity, social support, and acculturation on depression-stigma in college communities; specifically targeting the racial groups of African Americans and Whites. Undergraduates of various ages and class standings were given surveys within their demographics pertaining to: acculturation, social support, stigma, and depression. The above factors were compared to ethnicity. The results supported that African Americans have a higher level of depression-stigma overall, especially those who have been enculturated into their traditional culture; none of the additional hypotheses were supported by the research.

Music Influences On Health Compromising Behaviors, Erum Qureshi

HIM 1990-2015

Considering the vast number of youth that participate in sexual behavior and start using illicit drugs at a young age, it is imperative to investigate the prevalence of media filled with both subliminal and blatant messages about drugs and sexuality. It is hypothesized that lyrical content of music and the content and imagery of music videos will contain conscious messages about drug and alcohol use, and sexual behaviors. Content analysis that used the frequency method determined the amount of sexual and drug messages within five songs from each artist. Additionally, it is postulated that participants who frequently listen to specific …

Personality And Interpersonal Aspects Of The Work Environment, Roseann Swiden Wick

HIM 1990-2015

Workplace arrogance has emerged as a research focus area for many industrial-organizational psychologists. Employees who demonstrate arrogance tend to demonstrate poor job performance, executive failure and poor overall organizational success. The present study investigates arrogance measured by the Workplace Arrogance Scale (WARS: Johnson et al., 2010) in relation to the Honesty Humility facet of the HEXACO Personality Index-Revised (HEXACO PI-R: LEE & Ashton, 2004). A total of 273 participants completed the WARS and HEXACO PI-R Honesty-Humility Facet of the HEXACO. Results show significant, strong negative correlations between the Honesty-Humility subfacets and the overall Honesty Humility facet score with the WARS …

Fetal Alcohol Spectrum Disorders : Identifying Family Factors, Characterizing Child Behaviors, And Evaluating A Parent Education Program., Lauren B. Davis

College of Arts & Sciences Senior Theses

Fetal Alcohol Spectrum Disorders (FASD) refers to the group of conditions that results when a developing fetus is exposed to alcohol and is considered one of the leading causes of mental retardation and birth defects in the United States. Children with FASD typically have emotional and behavioral disabilities as well as poor academic functioning. Few empirically supported programs have been specifically designed for parents of children FASD. The present work aimed to evaluate a new FASD intervention and to identify characteristics of families raising a child with FASD. Thirty-one families with children ranging from 2 to 11 years of age …

Perceptions Of Interethnic Dating Among College Students, Elisaida Méndez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Department of Psychology at Utah State University proposed to examine the intersection of demographic variables. This phenomenon was studied in the context of power differential in relationships under the framework of social exchange theory and a racial hierarchy. The study examined the role of ethnicity, income, and gender in status and power balances in the perception of success of dating relationships. Social exchange theory explains the exchange of traits or resources in interpersonal relationships and relationship formation and based on a racial or ethnic hierarchy, race or ethnicity is seemingly overlooked when considering other valued traits.

Emotional And Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Alyson Kay Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effect of sex on how people react, emotionally and behaviorally, to different types of partner infidelity. We expected to replicate previous findings that men experience more jealousy in reaction to their partner's sexual infidelity, and women experience more jealousy in reaction to their partners' emotional infidelity. We hypothesized that sex will affect behavioral reactions to infidelity as well. Specifically, we expected men to respond to sexual infidelity by terminating the relationship and to emotional infidelity by employing mate-guarding behaviors to prevent further infidelity. We hypothesized women would display the opposite pattern, leaving a relationship in …

Motives For Different Types Of Medical Travelers: An Analysis Of The Current State Of Academic Research On The Topic, Dan B. Cormany

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research is to determine the current state of research undertaken to provide insight into the motivational characteristics of medical travelers, as reported by scholarly publications in the last five years. As a part of the study, an exploration is undertaken of the four basic schools of psychological thought, as each have different explanations for human motivation. These four schools - psychodynamic, behavioral, humanistic, and cognitive or pragmatic - are examined in the light of six categories of medical travelers. The categories are those traveling for life-saving surgeries, for treatments to improve quality of life, for elective …

Resilience And Trauma In Maltreated Youth, Timothy Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research into resilience represents a theoretical shift from the medical model in contemporary psychology to a focus on adaptation (Poulou, 2007). The relationship however between resilience and the development and PTSD in children remains unclear. The purpose of this present study is to expand on this research by investigating resilience and adaptability with respect to Posttraumatic Stress Disorder (PTSD) symptoms across maltreated youth of different ethnicities at risk for PTSD. Participants will be recruited from a Department of Family Services (DFS)-affiliated clinic in the Las Vegas area and administered the Children's PTSD Inventory (CPTSD-I), Behavior Assessment System for Children-2 Parent …

An Empirically-Supported Model Of Posttraumatic Stress Disorder In Maltreated Youth, Adrianna Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder in maltreated youth is a young and burgeoning field. Lemos-Miller and Kearney (2006) were among the first to propose and test a theoretically and empirically-based model of PTSD in maltreated youth. The present study replicated and evaluated the Lemos-Miller and Kearney model within a larger and more diverse sample of maltreated adolescents. First, the Lemos-Miller and Kearney model was tested via structural equation modeling (SEM). Second, the model was evaluated across age, gender, and ethnicity. Third, trauma history, family environment (i.e., cohesion and conflict), dissociation, and trauma-related cognitions were evaluated as potential mediating variables within the model. …

Olfactory Working Memory: The Role Of Perceived Odor Name-Ability, Spencer Lawrence Macadams

Masters Theses and Doctoral Dissertations

The purpose of this study was to examine the relationship among three factors: perceived odorant name ability, whether the odorant was ingested through a single nostril or both nostrils, and how the odorant is represented in working memory. Participants smelled odorants through the left or right nostril or with both nostrils and then provided an identifying label for each odor and rated how accurately their label represented the odor. After a short delay, the participants were given a new stimulus set consisting of new and old odorants. Participants were asked to provide a label for the odor and determine whether …

Understanding Organizational Wellness: The Impact Of Perceived Organizational Support, Motivation, And Barriers On The Effectiveness Of Wellness Programs, Aaron Owsley Manier

Masters Theses and Doctoral Dissertations

Organizational wellness programs can serve as a powerful tool for organizations to improve the health and well-being of employees. As organizational wellness grows in popularity and implementation, organizations should seek to understand employee perceptions of these programs to maximize their effectiveness and use. The present study examined the effect of perceived organizational support of wellness, core self-evaluation, and motivation/interest for wellness programs on wellness program use and satisfaction. This effect was tested with barriers to use and participative wellness design as possible mediators. Motivation and interest had a strong and direct effect on program use and satisfaction, while both organizational …

Challenge And Hinderance Stressor Appraisals, Personal Resources, And Work Engagement Among K-12 Teachers, Isaac Benjamin Thompson

Masters Theses and Doctoral Dissertations

Stress has long been conceptualized as consisting of two factors, eustress, or good stress, and distress, or bad stress (Selye, 1956). The occupational stress literature identifies challenge stressors as those associated with favorable outcomes, and hindrance stressors as those associated with negative outcomes (Cavanaugh, Boswell, Roehling, & Boudreau, 2000). The current study had three objectives: 1) to investigate occupational level stressor appraisal by K-12 teachers, 2) to explore how the perception of the availability of resources influences individual level stressor appraisal, and 3) to test differential outcomes of challenge and hindrance stress. Results indicate that K-12 teachers appraise workload as …

Accessing Learning In The Adult Zebrafish With A Novel Associative Learning Task, David Joseph Jouandot Ii

Dissertations

The zebrafish (Danio rerio) is accepted in the developmental and genomic communities as a model organism. However, the capacity for the zebrafish as a behavioral model has yet to be fully acknowledged. The research presented provides evidence validating the novel task, aids in gaining a better understanding of the learning processes, and identifies individual differences. The novel associative learning task differs from any present well established behavioral model and lends itself to future development. The task provides the zebrafish community with a high output behavioral task which is readily replicated and allows one researcher to test between eight …

Tactile Behavior In A Group Of Captive Rough-Toothed Dolphins As A Function Of Opportunities To Play With Objects, Kelly Ann Caffery

Dissertations

Cetaceans live in complex physical and social environments that are frequently changing. In contrast, the captive environment for marine mammals is often lacking in stimulation. As a result, enrichment is often used to increase species-typical behaviors and enhance the well-being of the animals. The purpose of this study was to compare the effects of enrichment objects on the social behavior of a group of seven captive rough-toothed dolphins (Steno bredanensis). Observations of this species in the wild suggest it may have a particular affinity for tactile and object play behaviors. Therefore, these behavior categories were a primary focus …

Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens

Dissertations

Socio-ecological theorists tie primate social structure diversity to variations in habitats within which primate species reside. This premise permits laboratory researchers to investigate specific factors that influence or relate to social structure formation and maintenance. The focus of the current investigation was three fold. We first aimed to determine the relationships between traditional and non-traditional behavioral measures of dominance, then evidence for dominance hierarchy formation was examined, and various hypotheses were tested to discern if adjustments in the foraging context altered social behaviors in Garnett’s bushbaby (Otolemur garnettii). It was determined that animals likely to displace conspecifics were …

Witnessing Reconciliation Reduces Arousal Of Bystanders In A Baboon Group (Papio Hamadryas Hamadryas), Peter G. Judge, Katherine A. Bachmann

Faculty Journal Articles

Reconciliation is the occurrence of friendly behaviour between opponents shortly after an aggressive conflict. In primate groups, reconciliation reduces aggression and post-conflict arousal. Aggression within a group can also increase arousal of bystanders (e.g. increase bystanders’ rates of self-directed behaviour). Since reconciliation reduces aggression between opponents, we tested whether it also reduces self-directed behaviour in bystanders. Following aggression in a captive group of hamadryas baboons, one observer conducted a focal sample on one of the combatants to document reconciliation and a second observer simultaneously conducted a focal sample on a randomly selected bystander. Matched control observations were then collected on …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …

It's Not So Simple: The Role Of Simplicity In Science And Theory., C. R. Gregg

Undergraduate Honors Theses

The principle of simplicity (parsimony) has long been invoked as a regulative principle that helps guide theory selection in science. However, it is unclear if there is justification for a globally applicable criterion of parsimony. This paper briefly reviews the salient features of what it means for something to be simple, as well as argues for simplicity as relevant only to a set of background assumptions.

Connection Between Cannabis Use And Psychosis And The Direct Vs. Indirect Form Of Inquiry To Combat Self-Report Bias, Lauren Grady

Psychology

The purpose of this paper is to investigate two problems: one clinical and one methodological. The first is whether there is a connection between drug use, and specifically cannabis use, and psychosis. Previous research on the subject has provided mixed results. Van Os et al. (2002) and Arseneault et al. (2002) both found that cannabis use predicted the onset of psychosis. Van Dam, Earleywine, & DiGiacomo (2008) found that the use of other drugs was a better predictor of psychosis than cannabis alone. The second problem involves how to maximize honesty when people answer questions regarding their own drug use. …
