Behavioral Effects And Neurobiological Mechanisms Of 3-Aminobenzimide In A Rodent Model Of Chronic Psychological Stress, Liza Wills

Electronic Theses and Dissertations

Major depressive disorder (MDD) is a leading cause of disability worldwide, with a lifetime prevalence rate of approximately 20%. Inadequate pharmacological treatment methods for MDD are a significant debilitating factor. Patient estimates suggest that the treatment resistance rate for pharmacological interventions is over 30%. Postmortem analyses of human tissue of individuals diagnosed with MDD have shown an increase in Poly (ADP-ribose) polymerase 1 (PARP-1) mRNA gene expression in prefrontal cortical white matter when compared to psychiatrically normal brain tissue. In order to further investigate this issue, the present study used the social defeat stress/chronic unpredictable stress (SDS + CUS) rodent …

Digital Manipulation Of Human Faces: Effects On Emotional Perception And Brain Activity, Martin Knoll

Electronic Theses and Dissertations

The study of human face-processing has granted insight into key adaptions across various social and biological functions. However, there is an overall lack of consistency regarding digital alteration styles of human-face stimuli. In order to investigate this, two independent studies were conducted examining unique effects of image construction and presentation. In the first study, three primary forms of stimuli presentation styles (color, black and white, cutout) were used across iterations of non-thatcherized/thatcherized and non-inverted/inverted presentations. Outcome measures included subjective reactions measured via ratings of perceived “grotesqueness,” and objective outcomes of N170 event-related potentials (ERPs) measured via encephalography. Results of subjective …

Taking Health-Risks As A Short-Term Mating Strategy, Alvin Jun Jie Wong

Dissertations and Theses Collection (Open Access)

Diseases pose a recurring, and often indiscriminate threat to the health of individuals. However, there exists a wide range of behavioral responses between individuals when it comes to taking health precautions or undertaking risks in response to this perennial threat, with some responses seeming maladaptive to an individual’s survival. The present study adopts the lens of evolutionary psychology and suggests that taking health risks represent a short-term mating strategy in men, which potentially trades survival for reproductive fitness. Taking health risks is hypothesized to be an honest signal of both good genes and a strong physiological immune system, both of …

Biological Sex Differences In The Monodelphis Domestica: Investigating Behavioral Responses In Environmental Enrichment And Conditioned Place Preference Paradigms, Katelynn M. Renteria

Theses and Dissertations

The Monodelphis domestica, commonly known as the grey short-tailed opossum, has become an increasingly frequented animal model for areas of psychological study, including comparative psychology. Despite the growing interest in utilizing the Monodelphis as an animal model, several areas of research remain limited in what has been studied. This includes associative learning and the effects of environmental enrichment on the Monodelphis. This study novelly incorporates the two using environmental enrichment with the conditioned place preference (CPP) paradigm to both diversify associative learning literature and expand existing knowledge on the Monodelphis domestica. The CPP paradigm included interactive objects as environmental …

Sunshine On My Shoulders Makes Me Happy... Especially If I’M Less Intelligent: How Sunlight And Intelligence Affect Happiness In Modern Society, Satoshi Kanazawa, Norman P. Li, Jose C. Yong

Research Collection School of Social Sciences

The savanna theory of happiness proposes that, due to evolutionary constraints on the human brain, situations and circumstances that would have increased our ancestors’ happiness may still increase our happiness today, and those that would have decreased their happiness then may still decrease ours today. It further proposes that, because general intelligence evolved to solve evolutionarily novel problems, this tendency may be stronger among less intelligent individuals. Because humans are a diurnal species that cannot see in the dark, darkness always represented danger to our ancestors and may still decrease our happiness today. Consistent with this prediction, the analysis of …

The Influence Of Pedestrian Biological Motion On Time-To-Collision Estimates At Night, Ellen C. Szubski

All Dissertations

The incidence of pedestrian fatalities has increased dramatically, and insufficient conspicuity at night has been identified as a significant problem. Placing retroreflective markings on a pedestrians’ extremities increases pedestrian conspicuity to drivers at night by capitalizing on our perceptual sensitivity to biological motion (biomotion). This study sought to determine whether biomotion also affects drivers’ ability to judge when they will arrive at pedestrian’s location. Here, 126 participants viewed prerecorded 25-second videos of a nighttime approach towards a walking pedestrian. The pedestrian wore one of five clothing configurations while walking from one of three approach angles. Prior to the vehicle reaching …

“I Can See The Forest For The Trees”: Examining Personality Traits With Trasformers, Alexander Moore

All Dissertations

Our understanding of Personality and its structure is rooted in linguistic studies operating under the assumptions made by the Lexical Hypothesis: personality characteristics that are important to a group of people will at some point be codified in their language, with the number of encoded representations of a personality characteristic indicating their importance. Qualitative and quantitative efforts in the dimension reduction of our lexicon throughout the mid-20^th century have played a vital role in the field’s eventual arrival at the widely accepted Five Factor Model (FFM). However, there are a number of presently unresolved conflicts regarding the breadth and …

The Comparative Effects Of Three Virtual Nature Exposure Methods On State Social Motivation: A Randomized Controlled Trial, Samantha A. Castelblanco

Electronic Theses and Dissertations

It is well established in the research literature that exposure to nature positively affects physical and mental health. However, research regarding the effects of nature exposure on social health is less developed. Prior research found that watching a video of nature improved state social motivation. Building on this research, the current study compared the effects of three methods of virtual nature exposure on state social motivation in a randomized controlled trial. In this 3X3 between-subjects experiment, participants (N = 426) 18 to 73 (M_Age = 27.69, SD = 12.19) were randomly assigned to experience 3-minutes of nature …

The Role Of Emotion Dysregulation In The Relationship Between Anhedonia And Opioid Craving, Rachelle Kromash

Electronic Theses and Dissertations

Research on factors that predict opioid cravings is lacking. Anhedonia may be a predictor of cravings and particularly relevant to cravings when people struggle to regulate emotions but has yet to be examined among justice-involved populations. This study aimed to examine the relationship between anhedonia, opioid cravings, and emotion dysregulation (ED) in this population. Participants completed several measures. The results showed that anhedonia and opioid cravings were significantly related at the bivariate level, but not in moderation models. The DERS-36 total score and ‘DERS Impulse’ subscale had a significant, positive effect on cravings in moderation models. In a higher severity …

Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz

Electronic Theses and Dissertations

Prenatal opioid exposure has been studied in relation to infants' medical outcomes. However, large gaps exist in the literature supporting early identification of atypical neurobehavior and motor development of infants with prenatal opioid exposure. The purpose of the study was to investigate whether prenatal opioid exposure has a negative influence on a newborn infant’s neurobehavior and motor development to aid in the early identification of potential delays. Using a prospective quasi experimental design, infants motor development using the Test of Infant Motor Performance (TIMP) and neurobehavior using the NICU Neonatal Network Scale (NNNS) was assessed on 58 infants in a …

Social Work Students' Understanding Of Childhood Psycho-Emotional Maltreatment By Caregivers, Todd M. Rubin

Electronic Theses, Projects, and Dissertations

Child psychological, emotional maltreatment (CPEM) presents to the social work profession as one of the most challenging to detect, prevent and intervene. The consequences of CPEM have been equally devastating to a child’s development compared to all other forms of childhood maltreatment. The purpose of this study is to assess graduate social work students’ knowledge of CPEM as a determinant of their clinical preparedness to work with families in practice. The rationale for this study is to explore how the lack of focus on CPEM in university education, field experience, and field supervision impacts a social worker’s ability to prioritize …

Doctoral Dissertations and Master's Theses

The purpose of the current project was to investigate the effect of utilizing Virtual Reality (VR) technologies for flight training by comparing the training results when using conventional desktop flight simulation versus VR flight simulation. Additionally, this project examined the user experience of VR flight simulation and how users’ motivation and satisfaction with VR simulations. This research employed a quasi-transfer of training experiment including 48 participants. Analyses indicated that VR group participants performed better in the post-training maneuver performance on an FTD than in the conventional desktop simulation group. Findings also supported that VR flight simulation could provide a better …

Building Resilience, Julie Jasewicz

Psychology

Amongst those most negatively impacted by the COVID-19 pandemic and other harmful events we find many examples of individuals who are able to “bounce back” from their adversities more easily than others. This reflects the concept of resilience—the process of positively adapting and evolving during and after experiencing adversity thereby becoming less vulnerable to future adversity. Due to a need to build resilience among college students, and without clear guidance as to how to do that, the present study investigated the effects of a resilience intervention. 232 college student participants were assigned to either an experimental group, who received the …

Psychometric Properties Of The Eating Disorder Examination Questionnaire: Factor Analysis And Measurement Invariance By The Intersection Of Race And Gender, Jessica H. Habashy

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Eating Disorder Examination Questionnaire (EDE-Q) was originally validated in non-Hispanic White women and over the past two decades has become widely used as an eating pathology screening measure in college students. However, the original factor structure has generally failed to replicate across most studies, particularly among culturally diverse samples. The current study examined the factor structure and measurement invariance of the EDE-Q in a large sample of gender and racially/ethnically diverse college students. Participants included a racially and ethnically diverse sample of men and women from two universities. I first conducted exploratory factory analysis (EFA) to examine the factor …

The Theory Of Mattering: Implications For Adolescent Depression And Suicidal Ideation, Josie Lucretia Bryan

Boise State University Theses and Dissertations

Recent studies have suggested that mattering may influence both self-esteem and depression, and the perception of not mattering can lead to suicide ideation, attempts, or completion. When young people perceive they matter to those in their social environment, that sense of mattering can act as a protective factor. Existing research supports the notion that mattering is salient to adolescent development and, importantly, potentially malleable which could make it a prevention/intervention factor. The current study endeavored to identify contributing factors to adolescent perceived mattering and to test the Theory of Mattering in an adolescent population when predicting mental health outcomes. A …

Measuring Srl Differences During Mathematics With Srl Microanalysis, Aliya Halterman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Self-regulated learning (SRL) is an essential skill for achievement and progress in several settings including academics. It is known that students with attention-deficit/hyperactivity disorder (ADHD) struggle with SRL skills. However, this knowledge has been acquired primarily from self-report measures. While this has provided a solid foundation within the literature regarding SRL skills within the population with ADHD, there are a few limitations that these measures posit. These limitations can addressed with a measurement called SRL microanalysis. The purpose of this study was to use SRL microanalysis to measure SRL differences between students with and without ADHD symptomatology during a mathematics …

Utilization Of The Fundamental Attribution Error With Increased Immune System Inflammation, John Odom

Biological Sciences Undergraduate Honors Theses

Immune system inflammation is associated with sickness behavior, depressive mood, and alteration of decision-making processes. Because of these cognitive effects, inflammation may also lead to increased use of heuristics, for example the Fundamental Attribution Error (FAE). In the current research, inflammation was experimentally increased using the influenza vaccine, with participants receiving either the vaccine or a placebo injection and completing a measure that tests for the FAE. There were no significant differences between the two conditions regarding the number of personal, situational, or overall attributions made by the participants in the measure that would indicate use of the FAE. However, …

Trait Anxiety In The Workplace: A Job Demands-Resources Perspective, Tessly Ann Dieguez

Theses and Dissertations

There is a widely held assumption that anxiety is always bad for job performance, when, in reality, the research findings on anxiety and performance are complex, varied, and inconsistent. Anxiety is extremely common and recently on the rise in the general population, and it can be related to important workplace outcomes such as job performance and well-being. Using the theoretical backdrops of the job demands-resources model (Bakker & Demerouti, 2007, 2018) and the theory of workplace anxiety (Cheng & McCarthy, 2018), this study proposed a model examining the mechanisms through which trait anxiety could lead to lower and higher typical …

The Art Of Nutrition, Kylanna Hardaway

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Many colleges and universities offer students access to on-campus food pantries, yet very few students utilize these services despite reporting high rates of food insecurity. Considering the importance of a healthy diet on the developing minds of young adults, it is pertinent that colleges and universities find innovative ways to reach food insecure students. The purpose of this hybrid creative-research project was to creatively address commonly cited barriers of seeking food assistance (i.e., negative stigma, embarrassment, unknown location, awareness of resource, etc.) using public art. A mural was designed to encourage healthy eating behaviors and provide signage for the Jane …

The Relationship Of Minority Stress With The Mental Health Of Lgbtq College Students On A Christian Campus With Non-Affirming Policies, Ethan Nicholas Smetana

Electronic Theses and Dissertations

One foundational concept of the Minority Stress Model (Meyer, 2003) is that the stress is based on persisting social processes and structures. Consequently, research to further the available pool of empirical evidence on how institutions based in the dominant culture affect minorities is needed and valuable. This study seeks to examine the effects of dimensions of minority stress on the mental health outcomes of LGBTQ students at a Christian university with a non-affirming school policy. Further, this study is interested in how gratitude affects the impact that minority stress has on mental health as a potential protective factor. Participants were …

Cognitive Tribalism: A Social Doxastic Model, Robert Ragsdale

Graduate Theses and Dissertations

How are facemasks – seemingly innocuous artifacts of the biomedical industry – currently embroiled in cultural wars? What motivates popular rejections of scientific consensus and messaging about the reality and consequences of anthropogenic climate change or the COVID-19 virus and vaccine? The puzzle is that (a) despite its being in everyone’s rational interests to have a well-informed public and body politic about collective threats, and (b) despite the public availability of accurate and reliable information, scientific messaging and public discourse surrounding climate change, COVID-19, and vaccine hesitancy, nevertheless, tend to be hijacked by political interest. Yet, if belief is essentially …

The Foundation Of A Grand Unified Metaphysics, Jason R. Miller

Graduate Theses and Dissertations

Philosophers from Leibniz to Parfit have tackled the problem of existence and the problem of arbitrarity. I divide the solutions to these two problems into three general categories: (1) infinite regress answers, (2) ex nihilo answers, and (3) self-caused cause answers. I show that the first two (infinite regress and ex nihilo) categories of answers either fail to answer the problem of existence or the problem of arbitrarity or fail to satisfy one or more reasonable assumptions about said problems. Believing it to be useful to a self-caused cause answer to the problem of existence and the problem of arbitrarily, …

Something Like A Phenomenon: High Achieving Women Of Color And Experiences Of Mental Health Resource Utilization, Andrea Hampton Hall

Graduate Theses and Dissertations

The purpose of this study was to examine, explore, and understand the lived experiences of high-achieving Black and Latina women who had utilized mental health services in the last 18 months. The impact of discrimination and stigma is present today and may manifest itself within communities of color when these individuals attempt to access mental health services. The counseling field and counselor education programs are ethically responsible for integrating social justice counseling into coursework and practice. This informs educators and counselors of barriers that may influence and impact best practices for providing mental health services to communities of color. A …

Punishment And Choice, Rafaela M. Fontes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Punishment is defined as a consequence that decreases the frequency of behavior that produces it and is an important behavior regulation mechanism for learning to stop engaging in maladaptive behavior. Punishment has implications for behavioral disorders and treatments and plays an important role in both programmed and natural contingencies. Despite the clear relevance of punishment for behavioral regulation, little is known about how punishment works. Furthermore, punishment research has been in evident decline, leaving important empirical and theoretical gaps in the literature. Therefore, the overall goal of the present set of studies is to fill in some of these gaps. …

Sex And Age Differences In Approach Behavior Toward A Port That Delivers Nicotine Vapor, Veronika Evangelina Espinoza

Open Access Theses & Dissertations

The goal of our laboratory is to study the mechanisms that promote nicotine use, particularly in vulnerable populations such as adolescents and females. Thus, the purpose of this thesis was to characterize age and sex differences in the motivational/rewarding effects of nicotine (Aim 1) and withdrawal behavior (Aim 2). To more closely model human use patterns, the present study employed nicotine vapor methods involving passive exposure for 14 days in adolescent and adult female and male rats. Age and sex differences in approach behavior (nosepokes) were assessed in a port that delivered nicotine plumes on Day 1 and 14. Controls …

Self-Determination Theory And Attachment Theory: An Integrative Model To Predict Drinking Motives And Protective Behavioral Strategies In Emerging Adults, Claudia Iliana Lopez

Open Access Theses & Dissertations

The integration of attachment theory and self-determination theory can be used to develop a statistical model to understand the association between attachment styles and basic psychological needs with drinking motives and protective behavioral strategies among emerging adults. Data collected from Prolific and UTEP (N = 437) was used in the present study to explore this possibility by examining the association between the variables of interest using linear regressions, SEM models, and moderated mediation models. Linear regressions demonstrated a statistically significant relationship between attachment styles, basic psychological needs, drinking motives and protective behavioral strategies. Although the complete and deconstructed SEM models …

Establishing The Construct And Concurrent Validity Of Psychological Cumulative Stress And The Moderating Effect Of Protective Factors To Drinking Outcomes, Carlos Portillo

Open Access Theses & Dissertations

Previous studies have examined the associations between types of psychological stress and alcohol consumption but have not adequately examined psychological stress from a cumulative perspective. The present study sought to examine if self-report measures representing chronic stress, acute stress, life events, traumatic life events, and daily hassles throughout one’s lifetime were associated with drinking outcomes obtained from an online sample of at-risk drinkers reporting drinking patterns in the previous 90 days. Furthermore, the present study sought to examine if an index of protective factors moderate the effects of psychological stress on drinking outcomes. It was hypothesized that (1) the measures …

Coping Strategies Mediate The Relation Between Executive Functions And Life Satisfaction In Middle And Late Adulthood: A Structural Equational Analysis, Hui Si Oh, Hwajin Yang

Research Collection School of Social Sciences

Recent studies have suggested that executive functions (EF) predict life satisfaction for older adults. However, the mechanism is not known. By analyzing a sample (N = 3,287, ages 32- 84 years) from the Midlife Development in the United States 2, we examined the mediational role of coping strategies in the relation between EF and life satisfaction. Both active coping and behavioral disengagement mediated the relation between EF and life satisfaction, and age significantly moderated the mediational pathways. Specifically, the positive effect of EF on active coping was more pronounced in middle-aged and older adults than in young adults. However, the …
