Forgiveness Of Self And Others: A Group Approach To The Treatment Of Ptsd And Other Trauma Related Experiences, Jarrod A. Mask Jan 2025

Forgiveness Of Self And Others: A Group Approach To The Treatment Of Ptsd And Other Trauma Related Experiences, Jarrod A. Mask

Psychology Doctoral Specialization Projects

Forgiveness is often misinterpreted as the act of forgetting what happened or offering one’s offender the ability to redeem themselves for their wrongdoings. This is simply not the case. Rather, forgiveness is the process of the individual making the unprovoked choice to release their resentment in their own voyage towards living a free and happy life without being imprisoned from the emotions un-forgiveness produces. Forgiveness, as it may be a necessary process for the individual is to attain a sense of peaceful acceptance and liberation from their pain, is not an easy process. Providing a peer-based support system in the …


Functional Stereotyping Of Women’S Self-Objectification As A Function Of Life History And Body Fat, Vienne Howay May 2024

Functional Stereotyping Of Women’S Self-Objectification As A Function Of Life History And Body Fat, Vienne Howay

Psychological Science Undergraduate Honors Theses

Individuals prioritize different goals as a function of stability in their environment, oftentimes leading people to prioritize reproduction in hostile ecologies. From this shift in priorities, perceivers could develop heuristics about how women may attempt to attract mates. Previous research suggests that higher levels of body fat are more attractive to men with a fast life history. With this awareness of men’s preferences in body fat, high-fat women from hostile ecologies could be expected to engage in more self-objectifying behavior in the service of mate attraction or attempting present themselves as objects of affection to men. This study tasked participants …


Examining The Effects Of Menstrual Cycle Phase And Hormonal Contraceptive Use On Women's Sleep, Charles Ethan Coombs May 2024

Examining The Effects Of Menstrual Cycle Phase And Hormonal Contraceptive Use On Women's Sleep, Charles Ethan Coombs

Psychological Science Undergraduate Honors Theses

Women overrepresent men for sub-optimal sleep, a consequence of hormone fluctuation in the menstrual cycle affecting sleep regulatory pathways. While research has examined the prevalence of sub-optimal sleep through cycle phases, little research has examined how hormonal contraceptives (HC’s) could similarly affect women’s sleep, while also neglecting to utilize subjective sleep measures. In this study, we examine subjective sleep quality among naturally cycling (NC) women, women using different HC types, and between active and inactive phase pill users by subjecting 463 women to a subjective sleep battery. We hypothesized that HC users would report more sub-optimal sleep than NC women. …


Cognitive Functioning In Well-Controlled Asthma, Erin Walsh Jan 2024

Cognitive Functioning In Well-Controlled Asthma, Erin Walsh

West Chester University Doctoral Projects

Asthma is a common lung disease that impacts lung functioning through inflammatory based mechanisms. Past research suggests that decreased blood oxygenation due to asthma attacks may impair cognitive capabilities (Irani et al., 2017). Moreover, the observed differences in cognition between those with and without asthma may be associated with disease severity or asthma control respectively in asthma populations. The current study explored differences in cognitive functioning between college students with and without self-reported asthma. Sociodemographic data, self-reported asthma severity, and measures of asthma control were collected. The current study did not find significant differences in measures of cognitive efficiency between …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal Jan 2024

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …


Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng Aug 2023

Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng

Electronic Thesis and Dissertation Repository

Nicotine dependence is causally linked to increased risk of mood/anxiety disorders in later life. Females are reported to experience a higher prevalence of anxiety/depressive disorders and challenges in smoking cessation therapies, suggesting a potential sex-specific response to nicotine exposure and mood/anxiety disorder risk. However, pre-clinical evidence of sex-specific responses to adolescent nicotine exposure is unclear. Thus, to determine any sex differences in anxiety/depressive-related outcomes, adolescent male and female Sprague Dawley rats received nicotine (0.4 mg/kg; 3x daily) or saline injections for 10 consecutive days, followed by behavioural testing, in-vivo electrophysiology and Western Blot analyses. Our results revealed that adolescent nicotine …


Predicting Suicide Attempt History: Self-Report And Objective Measures Of Pain, Boriana Lassiter Aug 2023

Predicting Suicide Attempt History: Self-Report And Objective Measures Of Pain, Boriana Lassiter

<strong> Theses and Dissertations </strong>

The aim of this study was to replicate a factor analysis of the Painful and Provocative Events Scale (PPES), to test whether commonly used self-report measures associated with the Interpersonal Theory of (IPTS) would predict suicide attempt status and suicidal history, and to test whether physical pain sensitivity would differentiate suicide attempers, ideators, and those with no suicidal history (controls). Factor analysis of the PPES yielded a 5-factor solution consisting of Rare and Illegal Activities, Abuse Experience, Dangerous Sports, Medical Trauma, and Body Modification. Only Abuse Experience predicted suicide attempt status and overall suicidal history. Abuse Experience, the Psychache Scale, …

The Associations Between Adolescent Motives For Social Media Use With Body Dysmorphia, Eating Disorder, And Anxiety And Depression Symptoms, Kaylan Melvin May 2023

The Associations Between Adolescent Motives For Social Media Use With Body Dysmorphia, Eating Disorder, And Anxiety And Depression Symptoms, Kaylan Melvin

Honors Theses

Adolescents spend a large amount of time on social media sites. This is notable, as adolescence is a crucial time for body image development. Additionally, recent findings suggest that using image-oriented social media sites, such as Facebook and Instagram, is associated with more body dissatisfaction and disordered eating. Among previous studies, certain social media motivations have been found to have an association with poor body satisfaction and well-being in adolescents. To our knowledge, no studies have directly examined the association between social media motivations and eating disorder, body dysmorphic disorder, and anxiety and depression symptoms in adolescents. The current study …


Burnout In Medical Assistants In Primary Care: Can Mindfulness Be A Solution?, Natalee D. Calais Mar 2023

Burnout In Medical Assistants In Primary Care: Can Mindfulness Be A Solution?, Natalee D. Calais

Electronic Theses and Dissertations

Burnout is described as feelings associated with emotional exhaustion, depersonalization of patients, and a loss of sense of personal accomplishment and it is unique to healthcare workers. Current research highlights this condition among physicians, nurses, and mid-level providers; however, insufficient research exists regarding the effects of burnout on medical assistants. Research led to mindfulness as a possible solution defined as an intentional regulation of attention and awareness of the present moment. This project sought to see if mindfulness practices could be utilized to mitigate the effects of burnout in medical assistants. It was hypothesized that mindfulness could be a solution. …


Effects Of Social Isolation And Adolescent Ethanol Exposure On Adult Drinking And Nicotine Co-Use, Jakob Shaykin Jan 2023

Effects Of Social Isolation And Adolescent Ethanol Exposure On Adult Drinking And Nicotine Co-Use, Jakob Shaykin

Theses and Dissertations--Psychology

Alcohol use often begins in adolescence and can lead to increased susceptibility to AUD in adulthood. Stress in the form of social isolation during adolescence can also prompt substance use disorders later in adulthood. This thesis determined if exposure to ethanol (EtOH) during adolescence and social isolation alters the trajectory of alcohol and nicotine intake during adulthood. In Experiment 1, adolescent male and female Sprague-Dawley rats were administered intermittent injections of EtOH (2g/kg 20% EtOH, IP) or saline (PND 28-41). EtOH consumption was measured in adulthood (PND 49-55) using a 2-bottle choice procedure where one bottle contained a 0.2% saccharin/15% …


Psychopathy And Insight Within An Incarcerated Population, Courtney Steinorth Jan 2023

Psychopathy And Insight Within An Incarcerated Population, Courtney Steinorth

MSU Graduate Theses

The clinical construct of psychopathy has been researched extensively relative to incarceration. Cognitive insight has shown to be related to prognosis and treatment outcomes with severe psychopathologies. There has been, however, limited research on both psychopathy and cognitive insight in relation to incarceration. The purpose of the present study was to examine the moderation of cognitive insight levels on rates of incarceration (the number of times someone has been incarcerated in a government detention facility) based on their level of self-reported psychopathic traits. A brief demographic questionnaire, the Beck Cognitive Insight Scale, and the Levenson Self-Report Psychopathy Scale were administered …


Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan Nov 2022

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.


The Effect Of Propionic Acid On The Habituation To Social And Non-Social Odour Cues In Adult Male Rats, Cashmeira-Dove P. Tyson Aug 2022

The Effect Of Propionic Acid On The Habituation To Social And Non-Social Odour Cues In Adult Male Rats, Cashmeira-Dove P. Tyson

Electronic Thesis and Dissertation Repository

The enteric bacterial metabolite, propionic acid (PPA), elicits physiological and behavioural changes in rodents reminiscent of autism spectrum disorder (ASD). This includes abnormal sensory processing and social behaviour. ASD may contribute to social deficits through impaired habituation; therefore, the present study examined the effects of intraperitoneal PPA on the habituation to social and non-social odours. Adult male rats were injected daily with PPA or the vehicle control, and for 3 days, habituated to a conspecific odour or vanilla extract for 10 minutes. On day 4, rats were exposed to a novel conspecific odour or almond extract for 10 minutes to …


Utility Of The Motivation To Change Lifestyle And Health Behaviors For Dementia Risk Reduction Scale (Mclhb-Drr) Based On A North American Sample, Angelina E. Witbeck Jun 2022

Utility Of The Motivation To Change Lifestyle And Health Behaviors For Dementia Risk Reduction Scale (Mclhb-Drr) Based On A North American Sample, Angelina E. Witbeck

Dissertations

As the population ages, the prevalence rates of dementia continue to increase. Without a cure or promising treatment for dementia, the best course of lowering the prevalence rates of dementia is through preventative measures. Through an electronic survey, the study utilized the MCLHB-DRR scale to determine whether (1) gender, age, educational background, and socioeconomic status will impact the motivational factors to change lifestyle and health behaviors to reduce the risk of developing dementia and (2) direct experiences with individuals that have a dementia diagnosis are likely to impact one's motivational factors to change lifestyle and health behaviors to reduce the …

Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox

Theses and Dissertations

Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (Mage = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …

Depression As A Moderator Of The Relationship Between Perceived Injustice And Neuropsychological Performance Validity Among Individuals Previously Diagnosed With A Concussion, Jeremiah Lum Dec 2021

Depression As A Moderator Of The Relationship Between Perceived Injustice And Neuropsychological Performance Validity Among Individuals Previously Diagnosed With A Concussion, Jeremiah Lum

Clinical Psychology Dissertations

Concussion is one of the most common conditions seen within rehabilitation and neuropsychology. Given that many concussions are diagnosed following litigation-associated injuries, it is unsurprising that malingered neurocognitive deficit (i.e., deliberate underperformance on cognitive instruments in the interest of secondary gain) has dominated the concussion literature. Although the identification of malingering is essential to ethical assessment, its presence or absence is not the sole determinant of performance validity as a whole. Rather, performance validity is a broad construct involving effort, which refers to examinees’ investment in performing at capacity levels; emerging research suggests this can be affected by psychological factors …

Academic Stressors, Perceived Stress, And Coping Strategies Among Undergraduate Students, Danielle J. Levin

Senior Honors Projects, 2020-current

Stress is common among college students and is a predominant factor interfering with academic performance. This study evaluated how college students perceive their level of stress, the coping strategies used, and the use of resources to offset stress offered by the university. This study showed that overall, undergraduate students at JMU experienced moderate levels of stress. Pressure to succeed, balancing coursework, and lack of motivation were the most prevalent academic stressors experienced by students. This study provides evidence that perceptions of stress greatly impact student behavior and use of coping strategies. Variation in coping strategies among students highlights the importance …


Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, Kaustubh Sharma Nov 2020

Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, Kaustubh Sharma

LSU Doctoral Dissertations

The neurohypophysial hormone oxytocin is involved in the regulation of social behaviors, including social recognition, pair bonding, and sex-specific parental behaviors in a variety of species. Oxytocin triggers these social behaviors by binding to oxytocin receptors (OXTR) in various parts of the brain. Oxytocin-induced sex-typical behavior, therefore, suggests a sexual dimorphic distribution of OXTR in the brain. In recent years, the oxytocin system in the brain received tremendous attention as a potential pharmacological target for treatment of many psychiatric disorders, such as anxiety, autism spectrum disorders, and even sex-specific psychiatric disorder like postpartum depression (PPD). An important problem and a …

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd Oct 2020

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd

Dissertations

Abstract

Up to 85% of nurses have reported exposure to incivility in the workplace (Hunt & Marini, 2012). The often-subtle nature of incivility toward nurses in a minority population may partially explain why it remains a problem. Healthcare organizations realize the need for civility to counter the high turnover rate, staff shortages, and low job satisfaction reported by nurses, but lack understanding of how nurses of a minority population perceive incivility and bullying. This study aimed to answer the research question how do nurses with minority representation experience incivility and bullying versus empowerment in the workplace? A descriptive phenomenological design …


Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose May 2020

Mental Associations And Music Therapy: Including The History Of Associationism And The Neurology Of Associations, Dianna Rose

Expressive Therapies Capstone Theses

Associations are formed in our minds based upon three elements: sensory experience, emotions, and memories. These associations, unique to each individual, dictate thoughts, beliefs, behaviors, and actions. Some are necessary and supportive, while others can be maladaptive. Established associations can be changed, and new associations can be formed, to align with a client’s goals. The literature presents a strong history of associationism, as well as a body of research that demonstrates the neurological processes of how mental associations are formed. There are also studies showing how music activates the brain. However, there is a lack of research which draws direct …

Life is filled with experiences that contribute to who we are, who we will become, and the social connections we make. We are constantly reflecting on past experiences, be it alone or with others, as well as thinking about what is to come and where we see ourselves in the future. Social and cognitive psychology research has focused on the processes behind autobiographical memory and episodic simulation. The link between collective memory and episodic simulation is the focus of the present study. The specific aim is to explore the potential link between reflecting on past experiences and imagining the future …


The Missing Moral Dimension: Perceptions Of Transgressions And The Moderating Role Of Moral Foundations On Psychological Distress, Hannah Reas Jan 2020

The Missing Moral Dimension: Perceptions Of Transgressions And The Moderating Role Of Moral Foundations On Psychological Distress, Hannah Reas

Clinical Psychology Dissertations

Anxiety and depression can be represented on a dimensional spectrum of negative affect, broadly termed psychological distress. Research has identified several factors that maintain negative emotion, but have neglected the possibility that individuals’ interpretations of moral issues in the larger macro-system affects their level of distress. Thus, the current study investigated the role of perceptions of moral transgressions, or cognitive interpretations of stimuli (“transgressions”) that violate beliefs about right and wrong, as a predictor of psychological distress. Furthermore, this study tested how perceptions of moral transgressions vary as a function of individuals’ own moral intuitions, or moral foundations. Participants ( …


The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker Dec 2019

The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations & Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …
