Predictors Of Depression In Different Subgroups Of Parkinson's Disease: A Neuroimaging Study, Yenny Gabriela Valenzuela

Electronic Theses, Projects, and Dissertations

Parkinson’s disease (PD) is one of the most debilitating neurodegenerative diseases in the world. PD is typically characterized by its motor symptoms which commonly include tremors, rigidity, postural instability, and repetitive or involuntary muscle movements. Some of the most common non-motor symptoms include cognitive impairment, personality changes, depression, and anxiety. Depression has shown to be a prominent symptom in individuals with PD which affects them at any point during disease progression. However, it has been suggested that depression is more common among individuals with early-onset PD compared to individuals with later onsets. Our first aim investigated depression rates among individuals …

Inter-Agency Collaborations Among Mental Health And Law Enforcement Professionals In San Bernardino County During Covid-19: A Qualitative Study, Sonya Mcisaac

Electronic Theses, Projects, and Dissertations

As first responders, law enforcement officers and mental health professionals are constantly sought after regarding the delivery of critical services to people in need. However, the COVID-19 pandemic brought almost everything to a halt. It is therefore important to understand how social services were delivered during the crisis. It has been assumed in the literature that interprofessional collaboration is an important service delivery framework. However, because COVID-19 is a relatively recent public health phenomenon, relevant studies on interprofessional collaboration between law enforcement officers and mental health professionals are scant, if not non-existent. This qualitative study addresses this gap by exploring …

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 …

The Effects Of Rejection Sensitivity On Attention And Performance Monitoring Event-Related Potentials, Elizabeth Ridley

Electronic Theses and Dissertations

Rejection sensitivity (RS) can have significant effects on interpersonal relationships. Previous research has shown the negative social effects of RS, but less is known about the cognitive implications of having high levels of RS. The current study examined the effect of RS on various event-related potential (ERP) components associated with performance monitoring (error-related negativity, ERN; feedback-related negativity, FRN) and attention (P300; late positive potential, LPP). Participants completed a social or nonsocial Flanker task and an emotional Stroop task. Results showed an increased ERN on error trials for individuals with higher RS. Although the FRN, P300, and LPP were not influenced …

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 …

Sorry, Locals Only: An Experimental Investigation Of The Affective, Behavioural, And Cognitive Consequences Of National Identity Denial, Nadyanna Binte Mohamed Majeed

Dissertations and Theses Collection (Open Access)

Existing literature shows that experiences of identity denial and questioning (IDQ) present two major consequences for racial minority groups: increased negative affect and behaviours to reassert one’s identity. The current thesis addresses two limitations in this literature—concerns about generalisability to non-US contexts, and potential consequences for cognitive functioning—by examining IDQ effects on individuals from distinct racial groups in Singapore. Through a correlational survey, Study 1 provided evidence for the incidence of IDQ in Singapore across the three racial groups, although IDQ reports were generally higher among racial minority groups (i.e., Malay and Indian) than the racial majority group (i.e., Chinese). …

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 …

Witnessing Parental Violence And Cyber Ipv Perpetration In Hispanic Emerging Adults: The Mediating Role Of Attitudes Toward Ipv, Ines Cano-Gonzalez, Ruby Charak, Ohad Gilbar, Rosa Viñas-Racionero, Megan K. Strait

Psychological Science Faculty Publications

Recent studies indicate that the perpetration of intimate partner violence via cyberspaces (cyber IPV), namely, psychological aggression, sexual aggression, and cyberstalking is high among emerging adults. However, little is known of the risk factors that lead to cyber IPV and far lesser within Hispanic adults. Based on the intergenerational transmission of violence hypothesis, the present study examined the indirect effect of witnessing parental violence during childhood on the three types of cyber IPV through attitudes condoning IPV in Hispanic men and women, separately. Participants were 1,136 Hispanic emerging adults in the age range of 18-29 years (M = 20.53 …

Internalized Racism Mediating The Effects Of Ethnic-Racial Socialization On Self-Esteem And Psychological Distress Among Asians And Asian Americans In The United States., Tianhong "Jojo" Yao

Electronic Theses and Dissertations

Research has indicated ethnic-racial socialization can influence one’s ethnic identity development including ethnic identity and internalized racism. However, there is limited empirical research directly examining the relation among ethnic-racial socialization, internalized racism, and psychological outcomes including self-esteem and psychological distress among Asian populations in the U.S. The current research explored the influences of the three dimensions of ethnic-racial socialization (cultural socialization-pluralism, promotion of mistrust, and preparation for bias) on two outcomes (i.e., self-esteem and psychological distress) through internalized racism as a mediator in a sample of 245 participants identified as Asian and Asian American adults currently residing in the U.S. …

Face In Teams: The Impact Of Political Skill On Shared Leadership Density In Face Culture Teams, Valerie Taryn Robbins-Roth

Theses and Dissertations

The need for organizations to effectively function in contexts that are global, interdependent, and team-oriented is increasing (Carson, 2005; Carson, Tesluk, & Marrone, 2007; Early & Gibson, 2002; Hoch et al., 2010; Pearce & Sims, 2000). Empirically, shared leadership has been repeatedly tied to higher performance. However, while shared leadership use has seldom been investigated in cultural contexts, shared leadership is theorized to be affected by culture. Face culture logic (in which self-worth is social worth) is another understudied construct that may have implications in global team performance. Though, face culture alone can provide conflicting speculations of shared leadership tendencies. …

Bias As A Worldview Engine, The Terminus A Quo Of The Problem Of Evil, Eric Spencer Mccrickard

Masters Theses

Evidential evil is an encompassing title for moral evil, natural disasters, disease, famine, divorce, suffering, or other calamities in life that yield dissatisfaction or discernable discomfort. This area of evidential evil is the focus of this paper generally, including the argument posed by William Rowe from evidential evil and contemporary treatments offered by Bruce Russell. The argumentation is God’s nonexistence from the platform, or derivative of no greater good observed or known, of the justification or allowance of evil. It is not a refutation of the premises, per se, but instead, the biases associated with them are de facto statements …

Screen Time, Sleep, And Anxiety, Michael Edward Turner

Theses, Dissertations and Culminating Projects

Prior literature has found evidence for a connection between screen time and a variety of negative health outcomes. These negative health outcomes include symptoms of both generalized and social anxiety, as well as sleep issues involving poorer sleep quality and less sleep overall. There is also evidence that screen time has dramatically increased as a result of the COVID-19 global pandemic. The present research project investigated the relationship between smartphone screen time and anxiety, both generalized and social, as well as sleep duration and sleep quality. This research project breaks down screen time into four separate domains, social media, video …

Implications For Global And Local Visual Processing In Individuals With Learning Disabilities, Riya Mody

Psychology Student Papers and Posters

Visual processing in humans is done by integrating and updating multiple streams of global and local sensory input. When this is not done smoothly, it becomes difficult to see the “big picture”, which has been found to have implications on emotion recognition, social skills, and conversation skills in individuals with Autism Spectrum Disorder (ASD) and other learning disabilities. Previous research in this field has aimed to direct ASD patients toward normative processing of the global features by developing and evaluating a filter which is intended to decrease local interference, or the prioritization of local details. This work attempts to utilize …

Fostering Forgiveness Through The Reach Forgiveness Model To Dispel The Angry Black Woman Trope, Demetrius Tamantha Golden

Doctoral Dissertations and Projects

For generations, the African American community has felt lingering reminders of the oppression of their ancestors. Consequently, this oppression may have inhibited forgiveness or the ability to forgive. Unforgiveness can be expressed in many forms, but most commonly as anger, bitterness, and rage. The American culture depicts the African American woman in the media as an “Angry Black Woman,” neglecting her existence as a pillar to her family and community and the stressors that accompany this role. Research is lacking around forgiveness models using the population of African American women. The purpose of this dissertation is to contribute to the …

Leaving The Faith: Factors That Lead To Emerging Adult Apostasy, Sammie Davis-Dyson

Doctoral Dissertations and Projects

The present qualitative study used the transcendental phenomenological model. It investigated the three parenting factors of modeling, style, and attachment and their impact on emerging adult decisions to leave the Christian faith of their upbringing. Six participants, ages 21-25, male and female, white or Hispanic college students yielded information demonstrating that the parenting factors mutually interacted with one another. If the parent or parents had a positive impact in the modeling factor, the same was true for attachment and style. A fourth focal point was whether the emerging young adult would seek out a community of faith of his or …

Refugee Perceptions Of Post-Migratory Stressors Impact On Pre-Existing Trauma, Christine Elizabeth Krauter

Doctoral Dissertations and Projects

Refugees are an ever-growing population across the world. Refugees leave their country to survive from the horrors and traumas many experiences. They arrive in countries oftentimes with little to no language proficiency, housing, finances, or employment. The stressors many of them face mixed with the trauma they experienced pre-arrival can be a heavy burden to carry. The purpose of this case study is to understand the perceptions of post-migratory stressors impact on pre-existing trauma for refugees at Matthew House in Vancouver, Canada. A constructivist approach is taken since the focus is on the situation from the participants’ point of views …

Coordination In Healthcare Multiteam Systems: A Qualitative Study Of Healthcare Meetings, Anna Wolf

All Theses

To facilitate optimal patient care and outcomes for in-patent cancer patients, healthcare organizations often rely upon the coordinated efforts between specialized teams of healthcare providers, working interdependently in a structure known as a Multiteam System (MTS). Healthcare meetings, such as Rounds, particularly those with an interdisciplinary element, may act as care coordination mechanisms for in-patient MTS. This research investigates an MTS operating within the Southeastern United States whose teams use Rounds and other meetings called SNAP Huddles, to facilitate patient care. Through qualitative analysis using interviews and observations, this exploratory study aims to elucidate research questions relating to how Rounds …

All Theses

Mental health apps have shown promise for improving mental health and quality of life in a variety of contexts, such as depression, anxiety, and stress. However, a limited amount of research aimed at understanding how app features and design can optimize the therapeutic benefits and adherence of such mental health apps exists. Consequently, the primary purpose of the current pilot study is to investigate the effect avatar customization on depressive symptoms, adherence, and motivation to use a mental health app. Furthermore, the secondary aim of the current pilot study is to examine whether specific app features, including journaling, mood tracking, …

The Ivory Tower: An Intersectional View On Gender And Ethnicity In Academia Before And After The Transition To Online Work, Chelsea Robbins

All Theses

A substantial body of research shows that female academics have faced lower salaries, fewer promotions, and lower rates of tenure than male academics. Proposed mechanisms include higher demands for unrewarded service in the teaching-research-service ratio and significant obstacles in balancing work and family. This study proposed the ‘Academic Tetrad,’ which includes the additional facet of home life, as an alternative to the traditional ‘Academic Trinity’ perspective. The present study utilized an intersectional perspective to examine the academic tetrad, key workplace variables, and work-life balance across the COVID-19 transition to online work. The findings countered previous research by showing equality on …

Dual Pathways To Burnout And Engagement: The Role Of Personal Goal Facilitation Through Work, Self-Discrepancy And Emotions, Bek Wuay Tang

Dissertations and Theses Collection (Open Access)

According to the job-person fit framework, workplace burnout is often exacerbated by mismatches between the characteristics of the employee and the organization. Consistent with this view, past research has found that employees who perceive low personal goal facilitation through work (PGFW) report higher levels of burnout. However, personal goals were often assessed nomothetically, based on the assumption that individuals across occupational groups share similar personal goals they would like to achieve through work. The current research took an idiographic approach by examining if PGFW assessed based on individuals’ uniquely defined personal goals would predict burnout and work engagement. In addition, …

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 …

On The Frontlines Of Covid-19: A Jd-R Approach To Better Understand Emergency Medicine Clinicians' Psychological Well-Being, Riley Mccallus Pegram

All Dissertations

Healthcare organizations have been heavily impacted by the COVID-19 pandemic, with emergency departments (EDs) facing especially large burdens. Increased patient volumes, fewer opportunities to disengage from work, and the persistence of the pandemic over many months continue to place demands on emergency medicine clinicians (EMC) and may elevate their levels of psychological stress. Psychological resilience and meaningful work experiences may protect EMC from these negative effects but may also be negatively impacted by high levels of ED crowding. Using the Job-Demands Resources model as a theoretical framework, this dissertation sough to explore how ED crowding (measured objectively and subjectively), psychological …

“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 …

Development And Testing Of The Mueller Assessment Of Transition (Mat): A Tool For Measuring Older Adults' Wellbeing When Transitioning Into Assisted Living Facilities, Kaitlin Mueller

All Dissertations

Transitions into assisted living facilities (ALFs) may influence older adults’ wellbeing. Positive influences on older adults’ wellbeing are referred to as adjustment strategies, whereas negative influences are called constraints to wellbeing. Theoretical underpinnings for these influences are found in the Hierarchical Leisure Constraints Theory and the Transition Process Framework. Past research indicates a few influences on older adults’ wellbeing, such as family relationships, perceived physical health, and connections to the community. However, no assessment existed to quantify their wellbeing when relocating into an ALF. Therefore, this dissertation details the development and factor structure of the Mueller Assessment of Transition (MAT), …

The Self-Invalidation Due To Emotion Scale (Sides): Development And Psychometric Properties, Regina E. Schreiber

Graduate Theses and Dissertations

Self-stigma involves internalized negative evaluation in people with a societally prescribed label (i.e., mental health diagnosis). Thus, measures of self-stigma due to mental illness exclude people without a diagnosis who may negatively evaluate themselves because of their emotions— a process we define as self-invalidation due to emotion. In the current research, I introduced a definition of self-invalidation due to emotion as distinct from self-stigma due to mental illness and emotion invalidation from others. After expert review of the item pool (Study 1), and exploratory (Study 2) and confirmatory factor analysis (Study 3), a 10-item scale for Self-Invalidation Due to Emotion …

The Effects Of Alcohol Intoxication And Threats To Masculinity On Engagement In Sexual Aggression: Results From A Web-Based Survey Design And Alcohol Administration Study, Tiffany Lynn Marcantonio

Graduate Theses and Dissertations

Background: Research examining the combined effects of men’s alcohol consumption and perceptions of their masculinity as precarious (e.g., viewing masculinity as easily threatened) on sexual aggression (SA) is lacking. The goal of this dissertation study was to assess if alcohol consumption and precarious masculinity are related to men’s SA via a web-administered survey (Study 1) and an in-person alcohol administration experiment (Study 2).

Methodology: In Study 1, two samples of young adult men (aged 18-30) were collected, 1) a community sample of 492 men and 2) a college sample of 478 men, to complete a 20-minute survey; participants answered questions …

Mindful And Authentic: Examining Leaders’ Impact On The Feedback Environment, Ché Lindsay Albowicz

Theses and Dissertations

The majority of what is currently known about mindfulness at work focuses on the individual benefits of being mindful (see Glomb, Duffy, Bono, & Yang, 2011; Good, et al., 2016), leaving an opportunity to understand the interpersonal impact of mindfulness at work. The current study tested whether mindful individuals, specifically mindful leaders, impact the work experience of their direct reports. Building on initial evidence (Leroy et al., 2015; Nubold, Quaquebeke, & Hulsheger, 2019) and strong theoretical ties (Kernis, 2002), supervisor mindfulness was a significant predictor of direct reports’ perception of authentic leadership behavior. Empathy was tested as a positive other-directed …
