(Nearly) All Roads Lead To Polarization: Cognitive Dissonance And The Inverse Relationship Between Polarization And Trivialization In The 2016 And 2020 Elections, Austin D. Eubanks

Graduate Theses and Dissertations

The present study investigated cognitive dissonance theory—in particular, outcome-based dissonance, i.e., dissonance experienced from facing an outcome inconsistent with ones’ choice (in this case, preferring the candidate who lost the election)—in electoral contexts using the 2016 and 2020 American National Election Studies data (ns = 3,648 and 7,453, respectively). The particularly negative context of the 2016 and 2020 elections offered an opportunity to make a novel direct empirical comparison of choice valence between “hard/positive choices” (i.e., between two “good” alternatives) and “hard/negative choices” (i.e., between two “bad” alternatives) using real-world data. Results showed that after the election, respondents who preferred …

Equity And Access To Care: Barriers To Diagnostic And Treatment Services For Black Families Of Autistic Youth, Harlee Onovbiona

Graduate Theses and Dissertations

Numerous barriers to diagnostic and treatment access are present for families concerned their child might have autism spectrum disorder (ASD; e.g., long waitlists, limited specialized providers). However, Black families of autistic youth may experience additional racial barriers (e.g.., racial microaggressions, perceived stigma) due to the intersectionality of their child's disorder and their identity as Black Americans, a group that is systematically minoritized in the United States. Despite the importance of early identification and intervention, little research has documented how these barriers to treatment participation may impact perceived treatment effectiveness, treatment satisfaction, and stress among Black families of autistic youth. This …

Examining Financial Knowledge Levels Of Students Of Color Versus White Students, Anecia Flewellen

Honors Theses

Social Cognitive Career Theory (SCCT) focuses on the way that cognitive factors such as self-efficacy interact with contextual factors, like race, to predict goal setting behaviors (Lent, 2013). The SCCT framework has shown to predict academic goal setting like intention to graduate, with higher academic self-efficacy resulting in higher graduation intention (White & Parrone-McGovern, 2017; Wu, 2018). One contextual factor that has an ability to affect academic self-efficacy is financial stress, which includes student debt (White & Parrone-McGovern, 2017). Students who are Black, Indigenous, and people of color (BIPOC) have more debt on average and a harder time paying off …

How Do Stress, Social Support, And Mental Health Relate In The Lives Of College Students?, Angel Moore

Honors Theses

Stress experienced in college can have considerable negative consequences upon those that experience it and do not properly cope. Perceived social support has repeatedly been found to act as buffer against these negative consequences and effects (Dwyer & Cummings, 2001). The present study sought to understand specific details surrounding the stress experienced by students, their current social support, and their mental health. Nine college student participants completed an interview about recent stress and measures related to social support and symptoms of mental health problems. Correlations among these factors revealed that overall social support is negatively associated with stress and mental …

Transdiagnostic Predictors Of Everyday Functioning: Examining The Relationships Of Depression And Reinforcement Learning, Nada Dalloul

Arts & Sciences Graduate Student Theses and Dissertations

Background and Hypothesis. Identifying the factors contributing to functional deficits in psychotic disorders is essential to developing effective interventions. To address gaps in the literature, the current study had several goals: examine whether there are differential relationships across domains of neurocognition and function, assess whether reinforcement learning is related to function, identify how and if predictors of function are transdiagnostic, determine whether depression and positive symptoms contribute to function, and to further explore whether the modality of assessing function impacts the observed relationships. Study Design. We examined the neurocognitive and symptomatic predictors of individual functional domains across three measures …

Longevity Bias, Ingroup Bias, And Culture: A Study In Modern Japan, Sophia Chier

Psychological Science Undergraduate Honors Theses

Japan has long been cited as the prime example of a collectivistic nation with many instances of ingroup bias, and is also known for its respect for things that are old. This research examined a proposed link between longevity bias, or the belief that things that are older are inherently better, and ingroup bias in a Japanese population by replicating the “art” domain in Eidelman et. al’s (2010) longevity bias study. Participants, undergraduates at a Japanese university, completed questionnaires that evaluated their aesthetic enjoyment of a painting, while also manipulating the participants’ knowledge of the artists’ nationality and the artwork’s …

The Origins Of The Iraq War: The Role Of Anthrax In The Weapons Of Mass Destruction Claims, John P. Koenig

Student Theses and Dissertations

The 2001 Anthrax Attacks were a critical factor in the Weapons of Mass Destruction (WMD) claims that sparked the Iraq War. Despite its significance, little systematic work has been done regarding the topic. Existing studies primarily focus on the role of the Military Industrial Complex and intelligence failures as the primary explanations for the origins of the Iraq War. These explanations are limited, as they rely on hindsight biases. This thesis contends that anthrax was the catalyst for WMD claims that sparked the Iraq War. The 2001 Anthrax Attacks reinforced the belief that Iraq harbored WMDs and posed a threat …

Does Using Clicker Questions Before Instruction Improve Students' Conceptual Understanding., Edward "Walker" Goshorn

College of Arts & Sciences Senior Theses

Active learning can be incorporated into STEM classrooms in multiple ways. With exploratory learning, students explore a novel activity before learning the concepts or procedures. With personal response devices (e.g., clickers), students respond to real-time questions posed during lecture. The current studies examined whether, and how, clicker questions can be used as exploratory learning, to improve students’ conceptual understanding and engagement over traditional instruction. Biology professors integrated clicker questions into a lecture, and either closed the clicker poll prior to (Restricted Clicker Experiment, N = 164) or after (Extended Clicker Experiment, N = 188) giving feedback to the class. Undergraduate …

Understanding The Role Of Emotion Regulation Tendencies In The Momentary Associations Between Negative Affect And Eating Disorder Behaviors., Coby D. Banet

College of Arts & Sciences Senior Theses

Background: Eating disorders (EDs) are becoming increasingly commonplace and are associated with a broad array of dangerous medical complications. Further, EDs frequently present alongside comorbid psychiatric disorders (e.g., depressive and anxiety-related disorders), which are known to both predict ED severity and reduce treatment efficacy. While diagnostic categorization persists, Fairburn et al.’s (1993) transdiagnostic model suggests EDs may be more closely related and maintained through core, shared symptoms. To assess ED maintenance, momentary triggers such as negative affect (NA) are becoming increasingly centralized. The present study examines the roles of depressive symptoms and worry in predicting and moderating the relationships among …

Exploring Sex Differences In Conditioned Place Aversion, Houda Hussein Chamseddine

Psychology Theses - Archive

Substance use disorder is a chronic condition characterized by cycles of intoxication, withdrawal, and relapse. Negative affective and somatic symptoms commonly accompany cessation of substance use. These symptoms can be incredibly aversive, to the extent that they can be classically conditioned to be associated with cues or environments. Women show greater cue-reactivity to drug-associated stimuli and progress from casual drug use to abuse at a faster rate compared to men. Human and animal literatures strongly suggests that these elevated vulnerabilities in females are associated with changes in levels of circulating ovarian hormones. Studies investigating sex differences and hormonal influences during …

Difference In Smoking Patterns And Quitting Status Between Premium And Non-Premium Cigar Users After Two Years Of Follow Up In Us Adults: Findings From The Population Assessment Of Tobacco And Health (Path) Study, 2016-2019, Sarah Valencia

Dissertations and Theses (Open Access)

Previous studies have described the demographics, purchasing behaviors, trends in frequencies of cigar use, and quitting status among cigar poly users, however, there has not been a study that evaluates differences in demographic characteristics and quitting status for premium and non-premium U.S. adult cigar users. This study used secondary data analyses of the Population Assessment of Tobacco and Health (PATH) Study public-use files dataset for adult traditional cigar users in wave 4 (2016-2018) and wave 5 (2018-2019). Traditional cigars were classified as premium or non-premium at wave 4 (2016-2018) using the brand and price per stick of cigar that was …

Viral Particle Detection In Wastewater, Katelyn Clark

Dissertations and Theses (Open Access)

Wastewater is an underutilized resource for recognizing the epidemiology of pathogen transmission and infections within a community that has the potential to mitigate disease outbreaks. Pathogens of public health concern, such as adenovirus, norovirus, and SARS-CoV-2, occur in wastewater from excretion of infected individuals. Despite the potential for wastewater pathogen data to predict future outbreaks, the relationship between viral shedding patterns in wastewater and case counts of infectious disease remains unclear. An evaluation of the peer-reviewed literature was conducted to compile characteristics of adenovirus, norovirus, and SARS-CoV-2 in the wastewater environment. These characteristics were considered in prioritizing the key pathogens …

The Substance Use Disorder Peer Workforce In Texas And The United States: Assessing And Addressing The Workforce Development And Economic Evaluation Gaps, Sierra Castedo De Martell

Dissertations and Theses (Open Access)

The infrastructure for addressing problematic substance use and substance use disorder (SUD) across the US has shortages in many areas, and suffered additional challenges during the COVID-19 pandemic. One method to address shortages in SUD care infrastructure relatively quickly is to expand the peer workforce delivering peer recovery support services (PRSS). This workforce has expanded to cover most US states over the past two decades, but gaps in the evidence base for peer workforce development and economic evaluations of PRSS have persisted. To address these gaps, three studies were undertaken with the following aims: (1) Conducted a systematic review of …

What Cognitive Processes Drive Attentional Bias, And How Does Stress Affect Them?, Colton L. Hunter

Graduate Theses and Dissertations

Attentional biases toward or away from emotionally evocative stimuli have been well documented and related to clinical outcomes such as social anxiety. Some work has suggested that stress modulates attentional biases, but there are a number of inconsistencies in this literature regarding the direction of that modulation, highlighting a need to examine moderators of that effect. Sex differences in stress effects could potentially explain this inconsistency, as acute stress can affect males and females differently. It is also possible that stress differentially influences multiple component processes underpinning attentional bias, but these processes have not been well character, and to date …

Examining The Role Of Pretrial Detention On The Juvenile Plea Process, Isabelle May Clough

Open Access Theses & Dissertations

Plea bargains are a necessary part of the criminal justice system as a whole, and the juvenile justice system more specifically. However, juveniles may be at a particular disadvantage when entering into a plea bargain as a result of their developmental capacities. Pretrial detention in particular might influence the quality of the final plea agreement that a juvenile accepts, as adolescents would be motivated towards the short-term goal of being released from detention. The current study aimed to examine the relationship between juvenile pretrial detention and plea discounts through mediating relationships with number of attorneys and time to plea. Data …

Does Watching Videos With Natural Scenery Restore Attentional Resources? A Critical Examination Through A Pre-Registered Within-Subject Experiment, Andree Hartanto, Nicole Lee Anne Teo, Verity Y. Q. Lua, Keith Tay, Nicole R. Y. Chen, Nadyanna M. Majeed

Research Collection School of Social Sciences

Existing studies have shown that direct exposure to a real nature environment has a restorative effect on attentional resources after a mentally fatiguing task. However, it remains unclear whether virtual nature simulations can serve as a substitute for real nature experienced in the outdoors to restore executive attention. Given the mixed findings in the literature, the present study sought to examine if viewing videos with natural scenery (vs. a control with urban scenery) restores participants’ working memory capacity – measured by an operation span task – in a high-powered pre-registered within-subject experimental study. Overall, our within-subject experiment did not find …

Self-Confidence And Hormonal Contraceptive Use, Abigail Doran

Biological Sciences Undergraduate Honors Theses

Hormonal contraceptives are widely used to regulate menstrual cycles, alleviate certain symptoms linked to reproductive hormones, and prevent pregnancy. However, women who take hormonal contraceptives may experience significant physical and psychological side effects such as increased rates of depression and changes in self-image. The current study examined self-confidence in women before beginning hormonal contraceptives and two months after using them. These participants were compared to a control group of naturally cycling women who were also assessed twice. I hypothesized that women would experience decreased feelings of self-confidence in several domains of their lives, compared to the naturally cycling women. Results …

College Success 101: Resilience And Mental Health Mediate The Relationship Between Adverse Childhood Experiences And College Functioning, Mackenzie Crook

Psychological Science Undergraduate Honors Theses

Adverse Childhood Experiences (ACEs) are potentially traumatic events that children experience during the first 18 years of their lives. They can lead to health risks, both physical and mental, later on in life (Felitti et al., 1998). One of the largest transitions a person will experience is the transition from being a child to becoming an adult. This transition is often paired with people entering college, and being able to function successfully in college is a vital part of this transition. College functioning is assessed through educational functioning, relational functioning, and psychological functioning (O’Donnell et al., 2018). The purpose of …

Frequency, Form, And Function Of Dyadic Questions In Children With Autism: A Childes Corpus Study, Rhiannon Luyster, Isabella Leiwant, Sudha Arunachalam

Emerson Authors, Researchers, & Creators

Children’s questions to their caregivers – and caregivers’ questions to their children – play an important role in child development. For children on the autism spectrum, who often experience cognitive, linguistic and social difficulties, prior research on questions has resulted in inconsistent and incomplete findings. The present study characterized the frequency, form, and function of queries posed by children on the autism spectrum (n = 12), non-spectrum peers (n =20), and parents using the Nadig ASD English Corpus in the Child Language Data Exchange System (CHILDES). Results suggested that children on the autism spectrum and their caregivers produced fewer questions …

Working Memory And Language Associations In Children With Autism Spectrum Disorder, Megan A. Goldfarb

LSU New Orleans Theses and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social communication and interaction, with repetitive behaviors or specialized interests. A range of language abilities is seen in ASD, with some having typical abilities and others severe impairments. Working memory (WM) deficits have also been found in some children with ASD. In typically developing, as well as non-ASD children with language deficits a strong relationship has been found between WM and language abilities. Although both language and WM deficits are often seen in ASD, the relationship between these deficits has been underexplored. The objective of this study is …

Individual Differences In Police Officers’ Decision Styles In Order Maintenance Policing, Damarrah Elisheba Jameson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Day-to-day police work tends to be in order maintenance policing. These encounters necessitate officer discretion in decision responses to manage them. These decision responses reflect an officer’s decision style which precedes the encounter and drives subsequent decision making to manage them. However, little is known about officer-level decision style. For example, whether an officer has a rational, intuitive, dependent, avoidant, or spontaneous decision style (Scott& Bruce, 1995). Police training in any format often lacks attention to decision styles. As such, an officer’s decision style is most likely associated with demographics (e.g., age, gender) and occupational self-efficacy – a reflection of …

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

Gender Differences In Internalizing Problems And Everyday Behaviors Associated With Executive Function In Children And Adolescents With Autism Spectrum Disorder, Hiroko Mullner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Many children with autism spectrum disorder (ASD) experience internalizing problems, and there was evidence suggesting that poor executive function (EF) predicted their internalizing problems. However, this association was primarily found in studies with male children with ASD. Therefore, the present study aimed to investigate gender differences in internalizing problems and everyday EF in ASD children (age 5-15) and examined the associations between internalizing problems and everyday EF.Method: This study examined neuropsychological assessment data of ASD children without intellectual disability. The study consisted of two groups: 1. ASD boys (n = 44), 2. ASD girls (n = 15). The study …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized …

Multiple Approaches To Examining Gender Norms In Romantic Relationships, Carrie Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Romantic relationships are essential to the human experience, and gender stereotypes are so ingrained they can be automatic. In this dissertation, I address three empirical questions through both quantitative and qualitative research methods, all of which contribute to the growing body of literature on gender norms and romantic relationships. In Chapter 2, I present a mixed-methods study that examines how heterosexual men reason about benevolent sexism. Results revealed themes of equality in the workplace and men’s roles as providers. In Chapter 4 I implemented a two-study research design to understand how heterosexual women and men reason about troubled romantic relationships. …

Examining The Effects Of Perspective-Taking And Empathetic Concern On Attractiveness Biases In Millennial And Generation X Adults, Stephanie Verba-Quinones

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effects of perspective-taking and empathetic concern on attractiveness biases and stereotypes in Generation X and Millennial adults. Such biases and stereotypes are pervasive and can lead to preferential treatment and differential outcomes for individuals of varying attractiveness levels (see Langlois et al., 2000 for review). Previous research suggests that social media may amplify the importance placed on attractiveness, particularly for women (Fardouly et al., 2015; Perloff, 2014; Tiggemann et al., 2014; Toma & Hancock, 2018). Given the negative impacts of biases and stereotypes, this study sought to investigate pathways to reduce attractiveness biases and stereotypes …

Fear Of Recurrence As A Mediator Of Illness Perception And Perceived Stress In Acute Myocardial Infarction Survivors, Sarah E. Zvonar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: The primary objective of this study is to evaluate fear of recurrence as a mediator of illness perception and perceived stress. This research will determine how illness perceptions and fear of recurrence affect perceived stress in the acute myocardial infarction (AMI) population. Other aims will observe how demographics predict patients who may experience increased fear of recurrence and stress in the AMI population, how the variables of fear of recurrence change over time, and if fear of recurrence is still a significant mediator after controlling for depression and anxiety.Rational/ Conceptual Basis/ Background: Acute myocardial infarctions (AMIs) are often accompanied …

On Versus Off-Campus Living: An Exploration Of College Students' Mental Well-Being, Sameer Siddiqui

Theses/Capstones/Creative Projects

The World Health Organization defines mental health as “a state of mental well-being that enables people to cope with the stresses of life, realize their abilities, learn well and work well, and contribute to their community” (“Mental Health,” 2022). Risk and protective factors can be used to predict mental health outcomes. Both positive and negative outcomes can be predicted, respectively. The categories of these include individual, relationship, community, and societal. When examining college students, it is most reasonable to study the relationship and community factors. This study examined whether living on or off campus impacts predicted mental health outcomes in …

Sensory Processing Disorder And Sensory Integration: Case Study, Ella Aerni

Theses/Capstones/Creative Projects

This project is a case study on my brother, Damien, who has sensory processing disorder. This included a treatment plan based on sensory integration. All activities were meant to activate the parts of his brain that help him to focus and be in alignment and included strategies for both school and home. These strategies included using chew necklaces, a weighted vest, and sensory integrative activities including being wrapped in a blanket before bed, using a mini trampoline, and doing wall pushups.

Damien’s family and teacher used these strategies in school and at home. The teacher found all of the strategies …
