Depressive Symptoms As A Moderator Of Diurnal Trends In Reward Seeking, Erick Albert William Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anhedonia, a cardinal symptom of a major depressive episode, is the decreased motivation to seek rewards. Individuals with depressive symptoms tend to report reduced positive affect, a distal measure of reward motivation, and engage in less reward-motivated behavior (i.e., reward seeking). However, diurnal rhythms may also influence reward-seeking. Both self-reported positive affect and behavioral measures of reward-seeking increase from the morning to the afternoon and then decreased in the evening. Therefore, the aim of this study was to examine whether reward-seeking varied across time of day and whether anhedonia moderated variation. Overall, reward-seeking did not vary across time of day. …

Differential Patterns Of Theta Activation Underlying Various Cognitive Control Strategies, Jarrod Eisma

Biomedical Engineering Undergraduate Honors Theses

In this study, EEG was recorded from 157 participants at the University of Arkansas as they performed three computer tasks that tested inhibitory control (Go/Nogo Task), proactive and reactive control (AX-Continuous Performance Task), and resolving response conflict (Global/Local Task- modified Flanker Task). Time-frequency analysis (ERSP) was the primary focus of this study, in order to take advantage of the temporal and frequential characteristics of EEG recordings. The ERSPs and following statistical analysis showed significantly higher midfrontal theta band (4-8 Hz) power values for target trials (those that required more cognitive control) than control trials, which indicated that the procedure was …

The Effects Of The Atypical Dopamine Uptake Inhibitor Ce-158 On Extracellular Dopamine In The Nucleus Accumbens, Julia Neri

Honors Scholar Theses

Major Depressive Disorder (MDD) is characterized by symptoms such as cognitive dysfunctions, inflammatory changes, and motivational symptoms such as amotivation, fatigue, and anergia. While depressed people are commonly treated by traditional antidepressants such as serotonin reuptake inhibitors (SSRIs), previous studies have reported that SSRI medications do not treat fatigue and anergia symptoms well, and in some cases, can even worsen those symptoms. Subjects treated with dopamine (DA) uptake inhibitors, on the other hand, have been less likely to report symptoms of anergia and fatigue compared to those treated with SSRIs. Common DA uptake inhibitors such as methylphenidate and amphetamines, however, …

The Associations Between Gender Role Stress, Media Usage, And Metacognition In Emerging Adults, Leslie Robertson

Masters Theses and Doctoral Dissertations

This research explores the relationship between electronic media consumption and gender role stress and whether these relationships are dependent upon metacognitive abilities. Student participants (n = 238) between the ages of 18 and 25 from the University of Tennessee at Chattanooga were recruited and completed self-report measures of both frequency and types of media usage, gender role stress, and metacognitive abilities. Results demonstrated that though there was no direct relationship between amount of media consumed and gender role stress, an interaction effect occurred between metacognitive abilities and amount of media consumed. Results indicated that individuals with lower metacognitive abilities who …

Emotional Intelligence Of Adults Raised In Different Family Structures, Mary Sloan

Masters Theses and Doctoral Dissertations

Emotional intelligence (EI) contributes to optimal social functioning and is predictive of numerous positive outcomes (Gallagher & Vella-Brodrick, 2008). Existing research has indicated a relationship between emotional development of an individual and the family system in which they were raised, however limited exploration has been done examining the influence of the family structure. The current study examined EI of adults raised in dual parent households, single mother households, and single father households. Four hundred and seventy-five participants from dual parent, single mother, and single father households responded to a series of measures assessing emotional intelligence, emotional competence, subjective happiness, and …

Introducing A Silverback To An Established Group Of Adult Female Western Gorillas (Gorilla Gorilla Gorilla), Claudia Martinez

Theses and Dissertations

In May of 2015, an attempt to introduce a new silverback (adult male) to an established group of six western lowland gorillas (Gorilla gorilla gorilla) housed at Gladys Porter Zoo failed. The introduction process was halted and only protected contact among the gorillas was allowed. On May 1, 2018 another introduction was initiated to three adult females.Twelve months of behavioral data were compared across three time periods and two environments. We predicted that an increase in agonistic and affiliative behaviors would occur while anxious behaviors would decrease. We observed a significant increase in affiliative behavior and a significant decrease in …

Error-Related Negativity And Feedback-Related Negativity On A Reinforcement Learning Task, Elizabeth Ridley

Electronic Theses and Dissertations

Event-related potentials play a significant role in error processing and attentional processes. Specifically, event-related negativity (ERN), feedback-related negativity (FRN), and the P300 are related to performance monitoring. The current study examined these components in relation to subjective probability, or confidence, regarding response accuracy on a complicated learning task. Results indicated that confidence ratings were not associated with any changes in ERN, FRN, or P300 amplitude. P300 amplitude did not vary according to participants’ subjective probabilities. ERN amplitude and FRN amplitude did not change throughout the task as participants learned. Future studies should consider the relationship between ERN and FRN using …

The Effects Of Optimism On Anti-Natalism, Faith L. Brown

Master's Theses

People sometimes hold opinions on others’ choices, particularly their reproductive decisions, as these choices are important decisions that impact the lives of multiple people. People can believe that everyone should have children (pro-natalism) or that everyone should refrain from having children (anti-natalism) or they can hold no position on the reproduction of others. The main justification for anti-natalism is that life contains more suffering than pleasure and that it would be better if new people were not born to experience this suffering. This is why some theorists argue that people reject anti-natalism irrespective of how bad …

Willingness To Seek Professional Help For Suicidal Thoughts: The Role Of Masculine Norms And Self-Stigma In Service Members, Samantha E. Daruwala

Master's Theses

Given the high rate of suicide, it is important to understand what barriers are preventing service members from seeking professional help for suicidal thoughts. Self-stigma and conformity to masculine norms, which are evident in the military culture, have been demonstrated as barriers to care in civilians. This study sought to better understand how these two factors are related to willingness to seek professional help for suicidal thoughts and a personal-emotional problem among service members. Specifically, we (1) identified service members’ willingness to seek help from a variety of sources for suicidal thoughts and a personal-emotional problem, (2) examined how conformity …

Toward The Development Of A Practitioner-Friendly Delay Tolerance Assessment And Treatment For Typically-Developing Children, Kaitlynn Mary Gokey

Theses and Dissertations

Delay discounting is the decrease in the value of a reinforcer as a function of the delay to the delivery of the reinforcer. Individuals who exhibit steep delay discounting are commonly referred to as ‘impulsive’ and are at a greater risk of behavior problems such as poor academic performance, addiction, and excessive risk-taking. One effective intervention is a concurrent activity, in which the individual must complete a task demand during the waiting period. Rules and rulegoverned behavior also play a critical role in improving delay discounting rates across populations, and may be used as an intervention to promote self-controlled responses. …

Assessing Patient Attitudes To Ward Genetic Testing For Hereditary Hematologic Malignancy, Addison Johnson

Dissertations and Theses (Open Access)

Since 2003, more than 15 genes have been identified to predispose to hereditary hematologic malignancy (HHM). Although the diagnostic yield of germline analysis for leukemia is similar to solid tumors, referral for genetic evaluation in adults with leukemia is underperformed. Identifying HHM is important for prognostication, treatment, and donor selection for hematopoietic stem cell transplant. No studies have examined leukemia patients’ attitudes toward genetic testing for HHM. This study aimed to assess leukemia patients’ attitudes toward genetic testing and elicit current perceived distress due to a leukemia diagnosis. Data were elicited through an electronic survey sent to 5,513 patients diagnosed …

How Resilience-Building Interventions Impact Parenting Stress And Cortisol Reactivity In Mothers With Adverse Childhood Experiences, Victoria Jones

Undergraduate Honors Theses

Research has found that adverse childhood experiences (ACEs) are associated with changes in both parenting stress and cortisol. Resilience-building interventions may be able to help diminish the effects of ACEs, thus impacting parenting stress and cortisol reactivity. This study aims to examine how two resilience-building interventions (emotion-based and behavior-based) will impact parenting stress and cortisol reactivity in mothers with ACEs. This project is in the preliminary stages of data collection; as such, this honors thesis will review the relevant literature, describe current methodology and proposed analyses, and discuss possible implications and future directions. Participants (goal N=100) undergo a pre-assessment where …

Maternal Stress And Child Internalizing Symptoms: Parent-Child Co-Regulation As A Proposed Mediator, Tatum Harvey

Undergraduate Honors Theses

The effects of maternal stress on child behavior, especially externalizing problems such as aggression, defiance, and lack of self-control, are well-established within psychological literature. Few studies, however, have examined the effects of maternal stress on child internalizing problems, such as loneliness, withdrawal, and symptoms of anxiety and depression. Moreover, there is much research within developmental psychology to support the notion that parent-child co-regulation, sometimes called dyadic synchrony, can predict child behavioral outcomes. Currently, researchers lack an understanding of how this process can interact with maternal stress to predict child internalizing symptoms. The following thesis details a multi-method assessment which is …

Adverse Childhood Experiences (Aces) And Temperament In Children Aged 14 To 36-Months, Elysabeth Sexton

Undergraduate Honors Theses

Researchers have explored the effects of early adverse life experiences (ACEs) on children’s developmental outcomes for decades. In this study, I explored whether ACEs in toddlerhood were associated with temperament. I tested the hypotheses that: 1) children who were determined to have a difficult temperamental profile would have higher parent-reported ACE scores than children with an easy temperamental profile, and 2) children’s temperament types would have stronger associations with abuse and neglect ACE scores than with household dysfunction ACE scores. Parents of 94 toddlers, who were between 14 and 36 months of age, completed online surveys on behalf of their …

Views Of Addiction Etiology Predict Religious Individuals’ Willingness To Help., Emily Brady, Joseph Barnet, Valerie Hoots, Andrea Clements

Undergraduate Honors Theses

Abstract

Views of addiction etiology predict religious individuals’ willingness to help.

Emily Brady, Valerie Hoots, Joseph Barnet, and Andrea Clements, Department of Psychology, East Tennessee State University.

Addiction to drugs and alcohol is an accrescent societal problem. Individuals with substance addiction face stigma in their daily lives, specifically from religious individuals as explored in this study. The stigma these religious individuals might portray could be related to their ideas on addiction etiology. The purpose of this project is to evaluate if different views of addiction etiology predict religious individuals’ willingness to help individuals with substance addition. Our hypothesis for this …

Creative Gender Expression Performativity As A Coping Mechanism For Minority Stress, Emerson A. Todd

Undergraduate Honors Theses

Creative Gender Expression Performativity may be a coping mechanism for dealing with minority stress in sexual and gender minority populations. The current study suggests the creation of a new scale that measures effortful presentation rather than directional presentation. Rather than examining whether someone identifies as masculine or feminine – the proposed model would instead look at how much effort an individual is putting into their gender expression. In this mixed methods study, participants (N = 187) completed a survey based on gender expression, minority stress, and mental health, while 10 participants completed a qualitative post-survey interview via email. Multiple regressions …

Aces, Onset Of Aggression, And Initiation Of Out-Of-Home Placements In A Sample Of Youth In Residential Treatment For Sexually Abusive Behavior, Teliyah Cobb

Undergraduate Honors Theses

Adverse Childhood Experiences (ACEs) exhibit a strong influence on later functioning in adolescence and adulthood, including impacts on physical and mental health, as well as behavioral and risk-related outcomes. Youth who have engaged in sexually abusive behaviors experience ACEs and negative outcomes at significantly elevated rates. The current study evaluates the relationship between ACEs and the youth’s own behavior and onset and length out-of-home placements, including family- or home-based, residential, and correctional placements. Data for this study consisted of archival records that were collected from a nonprofit inpatient treatment facility for adolescents who had engaged in sexually abusive behavior. The …

Test-Driving Interventions For Teachers To Improve Treatment Integrity, Viktoria Papp

Honors Theses

Teachers often have to implement interventions in the classroom to address challenging student behaviors. Such issues are often addressed during behavioral consultation which involves working with a specialized consultant, such as a school psychologist, to determine the most robust strategy that will predictably have the greatest impact in addressing the problematic behavior. Equally important in this intervention process is the application of any intervention technique or strategy in the manner in which it has been designed and investigated to work based on supporting research.

There is an increasing need for consultants to consider utilizing strategies that promote the adherence to …

Extreme Ideologies, Situational Factors, And Terrorists’ Target Selection, Evan Mudgett

Graduate Theses and Dissertations

The purpose of the current study is to examine how ideology and situational factors shape terrorist target selection in the United States. While a growing number of studies have examined target selection by terrorists, the current study is the first to consider how combinations of factors present situated opportunities for terrorists to select particular types of targets as opposed to others. Guided by the situational crime prevention approach, this study relies on data from the American Terrorism Study (ATS) to measure attributes of incidents perpetrated by far-right and Islamic extremists and target selection. The outcomes of interest include government versus …

Biological Sex As A Moderator Of The Association Of Military Sexual Trauma And Posttraumatic Stress Disorder Total And Symptom Cluster Severity, Hallie S. Tannahill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Posttraumatic stress disorder (PTSD) is a multifaceted disorder comprised of distinct symptom clusters and is commonly diagnosed in military service members/veterans (SM/Vs), particularly in those with history of military sexual trauma (MST). Evidence and theory suggest that females and males may have different traumatic responses following MST, though research investigating this association has limitations, such as modeling the sexes separately or not covarying for MST severity. The current study examined the moderating role of sex on the association of MST severity and PTSD total and symptom cluster severity. Participants were 1,161 SM/Vs (female: n = 782, 67.36%) who completed online …

Teachers’ Experience With Problematic Behavior And Educational Support: A Phenomenological Inquiry, Kristen Michelle Brashear

Antioch University Dissertations & Theses

This dissertation was conducted to discover how teachers of elementary and middle school-aged children experience the phenomenon of problematic behavior in their classrooms and the support they receive from the educational system in this regard. The literature review revealed that there is a dearth of research using a purely qualitative approach to exploring the experience of teachers in this area. The idea that teachers are rarely asked how they experience problematic behavior and support was evident in the findings of this study. I conducted this study using a phenomenological approach to interview six teachers from three states. The interviews were …

Tales Of Thriving: Identifying The Underpinnings Of Women's Success In Stem Careers, Sarah E. Thoman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Women remain underrepresented in U.S. science, technology, engineering, and math (STEM) fields. Prior research enumerates many challenges that women experience in STEM and suggests interventions that enhance women’s exposure to STEM, technical acumen in STEM, or offer STEM community. Identifying what enables women to thrive in STEM is a novel approach to extending these efforts using a strengths-based approach. I thus conducted a case study focused on understanding the experiences of successful women in the STEM workforce. Findings revealed three core characteristics to women’s STEM success: synergizing self and science, science career advancement and mastery, and being a STEM change …

The Effects Of Metformin On High-Fat Diet-Induced Neuroinflammation And Cognitive Impairment, Caleb Levine

Psychology

Chronic high-fat feeding is associated with neuroinflammation, cognitive impairment, and anxiety-linked behaviors in rats. Metformin, a popular treatment for type II diabetes, has been shown to attenuate metabolic dysregulation and weight gain associated with an obesogenic diet. We demonstrated that HFD caused elevated fasting blood glucose, glucose intolerance, and increased body weight without cognitive impairment or anxiety as measured by novel object recognition and open field testing. Further, we demonstrated that metformin did not produce cognitive impairment, which was a concern associated with its chronic use. Further work will elucidate the impact of chronic HFD and metformin treatment on molecular …

Preferences In Information Processing, Marginalized Identity, And Non-Monogamy: Understanding Factors In Suicide-Related Behavior Among Members Of The Alternative Sexuality Community, Robert J. Cramer, Jennifer Langhinrichsen-Rohling, Andrea R. Kaniuka, Corrine N. Wilsey, Annelise Mennicke, Susan Wright, Erika Montanaro, Jessamyn Bowling, Kristin E. Heron

Psychology Faculty Publications

Suicide-related behavior (SRB) is a mental health disparity experienced by the alternative sexuality community. We assessed mental health, relationship orientation, marginalized identities (i.e., sexual orientation minority, gender minority, racial minority, ethnic minority, and lower education), and preferences in information processing (PIP) as factors differentiating lifetime SRB groups. An online cross-sectional survey study was conducted in 2018. Members of the National Coalition for Sexual Freedom (NCSF; n = 334) took part. Bivariate analyses identified the following SRB risk factors: female and transgender/gender non-binary identity, sexual orientation minority identity, lower education, suicide attempt/death exposure, Need for Affect (NFA) Avoidance, depression, and anxiety. …

The Convergence Between Cultural Psychology And Developmental Science: Acculturation As An Exemplar, Seth J. Schwartz, Ágnes Szabó, Alan Meca, Colleen Ward, Charles R. Martinez Jr., Cory L. Cobb, Verónica Benet-Martínez, Jennifer B. Unger, Nadina Pantea

Psychology Faculty Publications

The present article proposes an integration between cultural psychology and developmental science. Such an integration would draw on the cultural-psychology principle of culture–psyche interactions, as well as on the developmental-science principle of person↔context relations. Our proposed integration centers on acculturation, which is inherently both cultural and developmental. Specifically, we propose that acculturation is governed by specific transactions between the individual and the cultural context, and that different types of international migrants (e.g., legal immigrants, undocumented immigrants, refugees, asylum seekers, crisis migrants) encounter quite different culture–psyche interactions and person↔context relations. We outline the ways in which various acculturation-related phenomena, such as …

F#@&!: Profanity As A Means Of Emotional Regulation, Nicholas Gregorich

Electronic Theses and Dissertations

Profanity is a commonplace occurrence in everyday conversation and society as whole. Previous studies have analyzed the reasons people use profanity as well as the function of profanity in various stressful situations, such as pain. Emotional regulation is a series of strategies people use to control and modify their emotions. One frequent target emotion to be regulated is anxiety, a state of fear which may elicit avoidance behaviors and defense reactions. However, no previous research has exclusively looked at profanity as a potential emotional regulation strategy. This study determined whether or not profanity was a useful emotional regulation strategy for …

Perceptual Characterization: On Perceptual Learning And Perspectival Sedimentation, Anthony Holdier

Graduate Theses and Dissertations

In her analysis of perspectival effects on perception, Susanna Siegel has argued that perceptual experience is directly rationally assessable and can thereby justify perceptual beliefs, save for in cases of epistemic downgrade or perceptual hijacking; I contend that the recalcitrance of known illusions poses an insurmountable problem for Siegel’s thesis. In its place, I argue that a model of perceptual learning informed by the dual-aspect framework of base-level cognitive architecture proposed by Elisabeth Camp successfully answers the questions motivating Siegel’s project in a manner that avoids such issues.

An Interdisciplinary Study To Understand Treatment Seeking Behavior Among Female Survivors Of Anorexia Nervosa, Meaghan Victoria Tipton

Graduate Theses and Dissertations

This study was done to examine what psychosocial factors influence treatment seeking behavior among female survivors of eating disorders. This study uses a mixed methods survey consisting of open-ended item questions regarding treatment experience and social environment, and close-ended items to measure constructs from the Health Belief Model. Fourteen participants were recruited for this study to retrospectively detail their experiences of treatment during their eating disorder. All fourteen participants identified as Caucasian, thirteen identified as female, one identified with other gender, each with a history of medically diagnosed anorexia nervosa. The mean of age of current participants was 29.46, and …

Peer Acceptance In The Lunchroom And Children’S Internalizing Symptoms, Jake Steggerda

Graduate Theses and Dissertations

There is evidence to suggest that the context of the school lunchrooms provides children with rich opportunities for enhancing or hampering the quality of their relationships (Craig, Gregus, Elledge, Pastrana, & Cavell, 2016; Steggerda et al., in preparation). Although past research has linked children’s peer acceptance to their level of internalizing symptoms, few studies have examined peer acceptance within the lunchroom context. This study extends that work by examining associations between lunchroom peer acceptance (assessed via self- and peer-reports) and children’s internalizing symptoms. Participants were 676 fourth-grade students (50.7% female; 42.7% Hispanic/Latino, 30.3% White, 10% Pacific Islander, and 17% other) …
