Factors Related To Obsessive-Compulsive Symptoms: Understanding The Contribution Of Disgust, Contamination Fear And Emotion Regulation, Alexandra Gilbert

Electronic Theses and Dissertations

The current study included 149 students from the University of Mississippi as apart of an archival dataset from a larger lab study. Results from the primary analyses indicate that all variables of interest (i.e. contamination fear, disgust sensitivity, and emotion regulation) were significantly correlated with OC symptoms. However, despite disgust’s associations with OC symptoms, results from regression analysis suggest that neither general disgust nor individual domains of disgust were predictive of contamination-based OC symptoms above and beyond contamination fear. Results from the hierarchical regression analysis emphasize the prominent role that contamination fear has on contamination-based OC symptoms. Further, sex differences …

Behavioral Similarities And Differences Among Symptoms Of Emetophobia, Disordered Eating, And Disgust, Jennifer Arden Petell

Electronic Theses and Dissertations

Emetophobia, also known as the specific phobia of vomiting (SPOV), is a clinical disorder with severe symptomatology and chronicity. However, there remains a significant lack of knowledge in overall conceptualization and etiological understanding. Recent literature has described this disorder within the context of abnormal eating disorders, despite the essential difference in symptom function between SPOV and disordered eating (Keyes & Veale, 2018; Volpe et al., 2015). Therefore, the present study sought to further the conceptualization and delineation of symptoms of emetophobia and disordered eating, as well as their potential relation with disgust. More specifically, it was hypothesized that symptoms of …

The Effects Of Differing Optical Stimuli On Depth Perception In Virtual Reality, Mckennon B. Mcmillian

Electronic Theses and Dissertations

It is well documented that egocentric depth perception is underestimated in virtual reality more often than not. Many studies have been done to try and understand why this underestimation happens and what variables affect it. While this underestimation can be shown consistently the degree of underestimation can strongly differ from study to study, with as much as 68% to as low as 6% underestimation, Jones et al. (2011, 2008); Knapp(1999); Richardson and Waller (2007). Many of these same studies use blind walking as a tool to measure depth perception. With no standardized blind walking method for virtual reality existing differing …

Does Early Screening Predict Special Education Placement By Age Five?, Samuel Josef Friedman

PCOM Psychology Dissertations

The Early Screening Inventory-Revised is an early childhood assessment used to screen three and four-year-olds entering preschool. This screener assesses basic skills and one’s level of functioning as he or she begins to learn in an academic environment. The purpose of this screener is to alert the school district about students who may struggle academically in a school- based setting. Based on the results of the assessment, students can receive academic or behavioral support from the school if the teacher and parents of the child deem the support necessary. Students who receive support from the school may or may not …

The Relationship Between Witnessing Domestic Violence And Criminal Recidivism Among Juvenile Sex Offenders, Shamyra Marie Shaw

PCOM Psychology Dissertations

This correlational archival dissertation focuses on the relationship between exposure to domestic violence and criminal recidivism among juvenile sexual offenders. The study examined archival criminal arrest records and self-reported data gathered from a sample of 67 male juvenile sexual offenders in a residential treatment facility. Given the somewhat limited explanations for and research into the causes of juvenile sexual re-offending and the importance of identifying its determinants, this topic may be viewed as having substantial importance to future research and criminal justice policy. Findings did not support the primary hypothesis that prior exposure to domestic violence would be positively correlated …

Telephone-Delivered Cognitive Behavioral Therapy For Insomnia In Patients With Cancer: A Randomized Controlled Trial, Andel Nicasio

Electronic Theses and Dissertations

This study examined the efficacy and feasibility of a brief telephone-delivered CBT-I (TeleCBT-I) intervention in cancer patients compared to a control group. The study used a randomized controlled trial design. The TeleCBT-I program consisted of a brief four-week CBT-I program adapted for cancer patients. Patients completed assessment measures at pre-treatment, post-treatment and one-month follow-up. Out of 184 patients screened, 39 were randomly assigned, and 35 (TeleCBT-I, n = 19; Control, n = 16) completed pre- and post-treatment measures and were included in the analyses. Compared to control group, the TeleCBT-I group reported decreased insomnia severity symptoms (p < .014), improved sleep quality (p < .023), and reduced dysfunctional beliefs about sleep (p = .039) at post-treatment with sustained treatment effects at one-month follow-up. Sleep measures yielded large effect sizes (Hedges' g, 0.84-2.7). Although the TeleCBT-I group indicated improvements in fatigue, general functioning, physical well-being, functional well-being, and physical quality of life, effects at follow-up were observed only for fatigue, functional well-being and physical quality of life. No effects were found on depression at any of the time points. In terms of feasibility, TeleCBT-I demonstrated high adherence, high homework completion and high overall satisfaction. These results advance the empirical evidence of CBT-I in cancer patients and support the use of telephone-delivered CBT-I to widely disseminate and implement among patients with cancer.

Long-Term Use Of Beta-Blocker Medication In Pediatric Long Qt Syndrome Patients: Neuropsychological Profiles, Kara J. Rudisill

PCOM Psychology Dissertations

Long QT syndrome (LQTS) is a heart rhythm disorder characterized by a disruption of the heart’s electrical activity that may cause accelerated and uncontrolled heartbeats referred to as ventricular fibrillation. LQTS is primarily treated with beta-blocker medications, which reduce the risk of experiencing an arrhythmia through regulating the heart rate. However, the potential neuropsychological side-effects associated with the use of beta-blocker medication may impact the executive functioning skills, mental health, and behavior of the affected pediatric population at home. As a result, a child’s academic performance and emotional regulation etiology may be misunderstood by his or her parents, caregivers, and …

Predictors Of Stress In Caregivers Of Family Members With Multiple Sclerosis, Lucy Lubinski

PCOM Psychology Dissertations

Multiple sclerosis (MS) is a disease of the central nervous system that typically results in cognitive and physical impairment. Depending upon the severity of symptoms, persons with MS often need assistance from caregivers in their daily lives. Research has shown that when a family member is diagnosed with the disease, household members become a source of caregiver support. The relationships between caregiver burden and chronic illness and between stress and health are well-documented. The impact of caregiving on individuals with MS remains a continued clinical concern, particularly because depression is highly co-occurring in those with the disease. Understanding the predictors …

A Hybrid Cognitive Architecture With Primal Affect And Physiology, Christopher L. Dancy

Faculty Journal Articles

Though computational cognitive architectures have been used to study several processes associated with human behavior, the study of integration of affect and emotion in these processes has been relatively sparse. Theory from affective science and affective neuroscience can be used to systematically integrate affect into cognitive architectures, particularly in areas where cognitive system behavior is known to be associated with physiological structure and behavior. I introduce a unified theory and model of human behavior that integrates physiology and primal affect with cognitive processes in a cognitive architecture. This new architecture gives a more tractable, mechanistic way to simulate affect-cognition interactions …

No Evidence That Portion Size Influences Food Consumption In Male Sprague Dawley Rats, Fabien Naniex, Sophie C. Pinder, Megan Y. Summers, Renee M. Rouleau, Eric Robinson, Kevin P. Myers, James E. Mccutcheon

Faculty Journal Articles

In studies of eating behavior that have been conducted in humans, the tendency to consume more when given larger portions of food, known as the portion size effect (PSE), is one of the most robust and widely replicated findings. Despite this, the mechanisms that underpin it are still unknown. In particular, it is unclear whether the PSE arises from higher-order social and cognitive processes that are unique to humans or, instead, reflects more fundamental processes that drive feeding, such as conditioned food-seeking. Importantly, studies in rodents and other animals have yet to show convincing evidence of a PSE. In this …

The Mediating Role Of Resilience In The Relationship Between Attachment Style And Symptoms Of Depression And Anxiety, Melanie Jurgensen

Honors Undergraduate Theses

Although previous research has identified a relationship between insecure attachment styles and symptoms of depression and anxiety, evidence regarding the mechanisms of action driving this relationship has been lacking. Consequently, the current study examined the mediating role of resilience in the relationship between insecure attachment styles (i.e. anxious-avoidant, anxious-ambivalent, helpless-disorganized and frightened-disorganized) and symptoms of depression and anxiety. The current study included a sample of 182 participants (i.e., 87 men and 95 women) who completed six questionnaires that assessed each participants' relationship with their caregivers during their childhood, present symptoms of depression and anxiety, and their resilience. Correlational analyses indicated …

Relationship Between Exposure To Nature In Childhood And Environmental Identity In Adulthood, Samantha Koss

Student Research Posters

It is a universal understanding that in order for nature to survive, humans must live responsibly. In October 2018 at the Intergovernmental Panel on Climate Change, the world’s leading scientists issued a twelve year ultimatum to change our environmental habits (National Geographic, 2018). However, the critical issue of climate change has not evoked a correspondingly serious and crucial response among the general public.

Ecological identity, otherwise known as Environmental identity, refers to how one views oneself in relation to the natural world, and a part of how we form our self-concept (Clayton, 2013).

Past research has shown that humans feel …

Effects Of Canines On Humans' Physiological And Perceived Stress, Beth Marie Bowin

Walden Dissertations and Doctoral Studies

The bond between pet and owner has been shown to decrease stress-related physical, mental, and emotional disorders by lowering blood pressure and heart rate. The purpose of this study was to examine whether a nonpet canine would have the same effect in reducing physical symptoms of stress as a known dog. Human-animal bond theory, Human pressor test. Data were analyzed using repeated measures, analyses of variance, and t tests. Results indicated that interaction with a strange dog lowered heart rate and blood pressure significantly faster in the experimental group than in the control group. The positive social change implications of …

The Impact Of Service Dogs On Combat Veterans With Posttraumatic Stress Disorder, Christine R. Hansen

Walden Dissertations and Doctoral Studies

Combat veterans with posttraumatic stress disorder (PTSD) related symptoms often require the use of complementary therapeutic aids, such as service dogs, to assist them in their recovery in addition to traditional evidence-based therapy. Anecdotal literature was available on the use of service dogs, but quantitative research has not been conducted to answer the question of what the impact was of the use of service dogs on reducing symptoms of PTSD among combat and non-combat veterans. Attachment theory was one of the most common theoretical frameworks for exploring the use of service dogs for treating combat PTSD. The theoretical framework for …

Suicide Attitudes And Terror Management Theory, Athena Kheibari

Theses and Dissertations--Social Work

Virtually every mental health problem carries stigma, but suicide appears to run so counter to our accumulative, achievement-oriented society, that it poses even greater threat of stigma. While suicide is inherently troubling in that it opposes the fundamental human instinct for self-preservation, the tendency to stigmatize and reject individuals affected by suicide appears to be counterproductive and excessive. Hence, the purpose of this three-manuscript dissertation is to gain a more nuanced understanding of suicide attitudes from an exploratory and terror management theory perspective. More specifically, this dissertation attempts to answer three general questions: (1) how do suicide attitudes differ from …

A Review Of The Use Of Positive Reinforcement In Drug Courts, Katherine Bascom

PCOM Psychology Dissertations

There is a need to provide effective treatment for drug-abusing offenders, as evidenced by the explicitly supported relationship between drug use and crime (Anglin & Perrochet, 1998; Tonry & Wilson, 1990; McBride & McCoy, 1993). Drug policy in the United States has viewed drug abuse as a public safety concern or a public health concern (Marlowe, 2002). In 1989, the Miami Drug Court in Dade County, Florida developed a drug court system that is currently used nationwide. The model embodies a very strong behavioral orientation with clear expectations, as well as graduated sanctions and rewards for successive infractions and accomplishments. …

The Use Of Personality Testing In Personnel Selection, Riya Kumar

CMC Senior Theses

Research has shown that more than 45% of American companies are opting to integrate personality tests in their recruitment processes. Given this surge in personality testing, this thesis examines whether personality testing is a valid predictor of job-fit and performance in the context of personnel selection. A large proportion of this paper is focused upon the Big-Five factor model, its limitations, and derivative tests of the model. The impact of technology upon personality testing is also discussed as an emerging field. By tracing and examining the history of personality testing to current day, I have found that personality tests are …

The relationship between individual and organizational performance is a key challenge for leaders in modern organizations, especially with the current disruption in technology and innovation. This thesis is a literature review and compilation of the relevant empirical evidence on various processes of industrial groups and organizational characteristics such as the changing nature of work, leadership, and company culture in detail. I investigate the complex challenges that millennials and organizations are facing in the current VUCA work environment as well as their potential responses to these changes. I map out the evolution of the concept of work and compare changes …

Finding Balance Between The Needs For Conformity And Individuality: An Exploration Of Identity, C.C. Schwab

CMC Senior Theses

Just as society has changed a lot within the past 100 years, the concept of identity has also evolved significantly. A big factor in the evolution of identity has been the realization that social and group phenomena influence all conceptualizations of identity. In this review, I explore identity through the lens of Optimal Distinctiveness theory (ODT), which proposes that humans have two opposing social motives (distinctiveness and inclusiveness) that position them amidst an internal battle over identity.

I start by defining identity and the self, including the distinction between the two. Next, I explore identity formation and different types of …

The Effects And Experiences Of Stigma In The Minneapolis Strip Club Industry, Machensey Shelgren

All Graduate Theses, Dissertations, and Other Capstone Projects

Utilizing participatory action research with dancers in the Minneapolis strip club industry, the present study examined current dancers’ experiences with stigma, its effects on their quality of life, and stigma management techniques. The present multi-methods study involved an initial survey and follow-up interviews with approximately 60 current dancers within Minneapolis strip clubs. Participants reported experiencing stigma in personal relationships and in the workplace, discrimination by landlords and future employers. Through thematic analysis, seven key themes were identified: dancer identity, assumptions made, loss of social support, profession weaponized against them, housing discrimination, lack of employment mobility, and identity concealment as stigma …

Relationship Between Novice Counselors' Supervisory Attachments And Boundary Practices And Perceptions, Glenda Hill Nanna

Walden Dissertations and Doctoral Studies

Novice counselors may struggle to understand and follow ethical guidelines for boundary behaviors with clients. When counselors violate therapeutic boundaries, harmful consequences can result for clients and counselors. The purpose of this quantitative study was to examine the possible relationship between novice counselors' (NCs') attachment to supervisors and NCs' ethical perceptions and boundary practices. This study addressed the possible predictor variables of age, gender, relationship status, and practice setting. Bowlby's attachment theory provided the framework for the study. Survey data from 114 NCs were analyzed using descriptive statistics and hierarchical linear regression. Each regression analyzed predictors of age, gender, relationship …

The Effect Media Has On Juror Bias, Tia Fasano

Honors College Theses

The purpose of the study was to illustrate the problems associated with juror bias and how the media contributes to it. The way the media portrays individuals, the language they use, and the pictures seen as affecting potential jurors when they determine verdicts of the people they hear about on the news. The study further investigates whether or not these jurors are influenced enough by the media to cause a bias detrimental to the defendant. The design of the study used multiple peer-reviewed sources, documentaries, and semi-structured interviews. Through these, information was gathered and analyzed. I found through the interviews …

Attitudes About Acceptable Risk In The Context Of The Biodiversity Crisis, Thomas Offer-Westort

Dissertations, Master's Theses and Master's Reports

Crafting and enforcing conservation policy requires making normative judgements about what levels of risk are acceptable. These judgements include crucial decisions that impact which species qualify as “endangered.” If a government’s policies are going to represent the values of the public they govern, then public attitudes should be understood. Unfortunately, essentially nothing is known about public attitudes as they pertain to acceptable risk and the biodiversity crisis.

My research aims to address this gap using data from an internet-based survey (n=1050). I focused on the Endangered Species Act of 1973 which defines an endangered species as “any species which is …

Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton

Scripps Senior Theses

Parenting behavior has been shown to have a wide range of effects, influencing children’s psychological and biological stress outcomes. Most research focuses on maternal parenting behaviors, with few studies observing the effects of paternal behaviors or the influence of both parents on their children. In this study, the relationship between maternal and paternal parenting behaviors was examined in its association to predict children’s cortisol levels. Cultural differences in parenting styles was also observed. American (N=86) and Chinese (N=97) families participated in the study, with parents reporting their behaviors. Children’s cortisol was collected during a stressor task and correlational analysis was …

Engagement And Stem Degree Completion: An Analysis Of The Relationship Between Time-To-Completion And Engagement And Pre-College Variables, Karina (Harstad) Clennon

All Graduate Theses, Dissertations, and Other Capstone Projects

This quantitative analysis explored measures influencing time to STEM-degree-completion in a correlational, non-experimental analysis of archival data (N = 745). FGCS represent a significant portion of individuals pursuing a post-secondary degree in the United States however, FGCS are less likely to persist to graduation as compared to their continuing-generation peers. FGCS are entering colleges and universities declaring STEM majors yet, are changing their major and or leaving college without a four-year degree (Chen, 2013). FGCS, who identify as female, face additional barriers, whether perceived or actual, in the pursuit of earning a STEM degree. FGCS choose to pursue STEM majors, …

A Non-Selective Serotonin Antagonist Promotes Rapid Habituation In The Terrestrial Hermit Crab, Kirandeep Sumra, W. David Stahlman

Psychological Science Articles

Research has indicated that serotonin (5-HT) modulates non-associative learning in a variety of invertebrate species. Recent work has demonstrated that the terrestrial hermit crab is a suitable animal model for non-associative learning phenomena, including habituation, sensitization, and dishabituation. We examined the potential role of a non-selective 5-HT antagonist, methysergide, in non-associative learning in the hermit crab. We administered methysergide prior to delivering repeated stimulus presentations of a looming visual predator. We found evidence for more rapid habituation relative to a control condition in which crabs did not receive the drug. These results indicate a role for 5-HT in the defensive …

Sheeple? The Need For More Research On Sheep Cognition, Michael Colombo, Damian Scarf

Animal Sentience

Marino & Merskin (2019) provide a comprehensive review of the cognitive abilities of sheep. If research with other animals is any guide, there may be justification for the view that the abilities of sheep have been underestimated, and their review will likely stimulate more research into sheep cognition.

Why Are Sheep Sheepish? How Perception Affects Animal Stereotyping, Robert G. Franklin Jr.

Animal Sentience

Marino & Merskin present compelling evidence that many stereotypes of sheep are incorrect. One factor that may play an important role in animal stereotyping is the physical appearance of animals, which can directly lead to stereotyping through automatic mental processes. Sheep have a round and babyish appearance that directly evokes judgments of warmth and docility. Depictions of sheep in art, and especially cartoons, reinforce this stereotype.

Sheep In Aesop’S And Phaedrus’S Fables, Matteo Colombo, Chiara Raucea

Animal Sentience

Sheep feature in various animal fables. Marino & Merskin suggest that “we” view sheep as “docile, passive, unintelligent, and timid,” but animal fables do not support this view. In Aesop’s and Phaedrus’s fables, sheep are a primary target of injustice; but they are not passive targets. Sheep endure injustice actively and honestly. They are intelligent, aware and outspoken about their own condition.

Time To Vary The Formula, Jon Mallatt

Animal Sentience

In the past few years, Marino and her colleagues have written a series of comprehensive and helpful review articles on the cognitive, emotional, and social complexity of pigs, chickens, cows, and most recently, sheep. These articles are similarly structured, even formulaic, which has benefits but also limitations. Here, I point out the limitations in order to suggest new directions and contributions for the authors in the future.
