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

<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, …

Cerebral Hyperemia Is Not A Sole Modulator Of Postexercise Executive Function Benefit: Evidence From Hypercapnia And Passive Exercise, Mustafa Shirzad

Electronic Thesis and Dissertation Repository

A single bout of exercise improves executive function (EF); however, the physiological mechanism(s) contributing to this benefit are unclear. One candidate mechanism for the benefit is an exercised-mediated increase in cerebral blood flow (CBF) that improves neural efficiency. In my thesis, I conducted two experiments to assess the relationship between an increase in CBF and EF. In Experiment 1, I examined passive exercise, and in Experiment 2, I examined a 2.5% hypercapnic environment given that both interventions increase CBF independent of the metabolic demands of volitional muscle activity. Experiment 1 indicated that passive exercise increased CBF and was associated with …

Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes

Graduate School of Biomedical Sciences Theses and Dissertations

The locus coeruleus (LC), the primary site of brain norepinephrine (NE), is a key anatomical brain region implicated in the stress response. Stress is a neuroendocrine physiologic response to a stressor that promotes organism survival through adaptive change and restoration of homeostasis. The central stress response, which drives behavioral and physiological change, is primarily mediated by activating the hypothalamic-pituitary-adrenal (HPA) axis. While advantageous in the short term, chronic stress exposure can lead to HPA axis and LC dysregulation, which are thought to contribute to the etiology of anxiety disorders. Previous studies demonstrate the effects of acute stress in increasing LC …

Tempers Rising: The Effect Of Heat On Spite, Jake C. Cosgrove

Master's Theses

The relationship between heat and harmful outcomes is well documented, with research connecting various adverse economic outcomes to the climate. In the presence of increasing global warming and climate change, understanding why the climate leads to negative economic outcomes is essential for forming peaceful institutions of the future. We study how behavioral economic outcomes change in the presence of heat through a lab experiment involving 1,110 observations conducted in five different countries. This paper specifically focuses on the social preference outcome of spite. We find that increased time exposure to the treatment effect of heat is required to elicit an …

Sleep Duration Is Associated With Caudate Volume And Executive Function, Nicole Jones

Honors Theses

The ineligible role of the caudate nucleus in sleep has been implicated throughout multiple scientific studies. Previous literature has shown that greater caudate volume is associated with longer habitual sleep duration in older adults- ranging from 55 years of age and up. However, the association between sleep duration and caudate volume remains unknown in the younger population. In this study, we examined the caudate volume in youth to older adults (10 to 85 years old) with a greater sample size (N=464) to increase statistical power. The volumetric size of the caudate nucleus showed significantly positive association with habitual sleep duration, …

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 …

Genetic Influences On The Response To Neuromodulation In Craving Behaviors, Carly J. Haring

Honors Thesis

Obesity and eating disorders are highly prevalent in the United States. People who suffer from obesity and/or eating disorders face serious health consequences and even death. Current treatments are not effective as recovery rates are low, so there is a dire need for an effective treatment for obesity and eating disorders. There have been studies investigating the use of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) of the dorsolateral prefrontal cortex (DLPFC) as a means of treatment for these people. While findings show promise, there is much variability. The goal of this study is to further prior …

Characterization Of Differential Rearing And Sex On 5-Ht2ar Receptor Activation, Kelsey Lowe

Theses/Capstones/Creative Projects

The prevalence of substance use disorders (SUDs) continues to rise while the number of medications to combat this deadly disorder remains stagnant. Entirely new thinking about what exemplifies a possible therapeutic is needed. Hallucinogens are continually being studied more as possible treatments for many psychological conditions, including SUDs. Classic hallucinogens engage many serotonin and monoamine systems, but the hallucinogenic effects are driven by serotonin 5-HT_2A receptor (5-HT_2AR) activation. Forced social isolation induces chronic stress, increases 5-HT_2AR expression in the cortex and have been suggested to play a role in the comorbidity between stress, maladaptive coping, …

Children’S Disclosure Of School Bullying: The Relation Between Peer Victimization, Internalizing Symptoms, Negative Affect, And Gender, Julia L. Kiefer

Graduate Theses and Dissertations

Children who are bullied by their peers are at risk for several negative developmental outcomes and are therefore advised to tell an adult when they are. However, victims of school bullying are often reluctant to disclose to adults that they are being bullied. Some bullied children also experience symptoms of anxiety or depression, which could further reduce their likelihood of telling an adult. In this study, I tested the degree to which children’s internalizing symptoms predicted their likelihood of telling adults about being bullied at school, and if this relation was exacerbated by children’s negative feelings associated with telling an …

Examining The Effects Of A Zoom Interview On Cortisol, Bennett Perkins

Psychological Science Undergraduate Honors Theses

The stress response is an essential physiological process that facilitates survival in threatening conditions. Stress impacts numerous bodily systems, and prior work has focused on cortisol, a steroid derived from cholesterol, as a key biomarker for assessing biological stress reactivity in humans. Social stressors are known to contribute to marked increased in cortisol levels, but to date little work has examined whether social situations known to be stressful in person can influence cortisol when those situations occur remotely. In this study, I investigated the effects of a Zoom-based social stressor on salivary cortisol. Participants were randomly assigned to the Zoom-stress …

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. …

Prenatal Ethanol Exposure Impairs Performance On Spatial And Tactile Sequential Discrimination Task In Juvenile Rats, Caleb S. Bailey

Theses and Dissertations--Psychology

Fetal alcohol spectrum disorders (FASDs) are a set of cognitive and behavioral abnormalities that arise in ~5% of children who have been prenatally-exposed to alcohol. Prenatal alcohol exposure (PAE) can cause impairments in learning acquisition, working memory, response inhibition, and attentional-set shifting that result in exaggerated deficits in executive function and impairments in goal-seeking behavior. There are standard procedures used in rodent research to address some components of these deficits, but few procedures are sensitive enough to comprehensively assess such deficits. To address this issue in FASDs research techniques, we developed a procedure that requires prolonged executive function in a …

Despicable Me: Shame And Guilt On Self-Avoidance Behaviours – An Eye-Tracking Study, Shuai Shao

Senior Projects Fall 2023

Shame and guilt are often used interchangeably in our daily lives, however, this project aims to differentiate between the two emotions based on people’s self-avoidance behaviours. Existing theories propose that while feelings of shame lead to increased self-avoidance behaviours, feelings of guilt do not. Using a modernised version of the mirror paradigm, this project captured participants’ gaze behaviours around their own face reflections. In this pre-registered study, the gaze behaviour of 30 participants were collected while emotions (either shame or guilt) were induced. Their state shame and guilt as well as trait shame and guilt were also collected through self-reports. …

Unique Posttraumatic Growth Expression Among Homeless Males Currently Enrolled In Chemical Dependency Treatment, Travis T. Mord

Theses and Graduate Projects

Posttraumatic growth (PTG) has gained considerable research and clinical attention for the past three decades. While the impact of PTG has been well-researched in relation to trauma exposure, medical ailments, or mood related conditions, there are still a number of mental health conditions requiring further analysis. The current study examined the relationship between PTG and key substance use significance indicators, including diagnostic severity of the use disorder and number of previous substance use treatment attempts, among a sample (N = 136) of adult men who were enrolled in a mental illness/chemical dependency (MICD) intensive outpatient program (IOP). This study also …

Evaluating The Acute Effect Of Vaping On Food Intake, Gabrielle Maldonado

Theses and Dissertations

Background: Weight control is a common motive for continued cigarette smoking, and weight concerns pose a barrier to quitting. These effects are driven in part by nicotine’s ability to reduce overall appetite and ultimately body weight. Electronic nicotine delivery systems (ENDS) have been marketed and used for weight control, suggesting that the use of these products potentially may share similar effects as well as barriers to quitting as observed for cigarette smoking. However, little to no controlled clinical lab evidence exists supporting ENDS use for weight control. The present study tested the influence of an ENDS on acute eating behavior …

Neurobiology Of Ptsd In Adults And Children: The Impact Of Stress-Induced Brain Abnormalities Across The Lifespan, Catherine Clover

Undergraduate Honors Theses

In the scholarly community, there is disagreement about the effects of PTSD or chronic stress on the brain of adults and children. Though PTSD or chronic stress are known to negatively affect neurobiological structures, specifically due to prolonged glucocorticoid excess, volumetric discrepancies between traumatized and control groups are not unanimously confirmed. This review sought to address the common understandings in academia of the effects of PTSD on the brains of adults and children. Literature on this topic indicated that, in adults, the hippocampus, cingulate gyrus, and prefrontal cortex bilaterally appeared to decrease in gray matter volume and the corpus callosum …

Physiological Responses Regarding Stress And Trauma: The Freeze Response, Emma Arie Von Holten

UNF Graduate Theses and Dissertations

Fight-or-flight is a commonly known response to threatening situations, but the freeze response is another defensive mechanism that might arise in such situations. There is also evidence that exposure to trauma can impact physiological reactions when defensive mechanisms are not required, such as freezing in response to non-threatening situations. The current study aimed to replicate and expand upon a limited number of previous studies on the human freeze response by implementing measurements of postural sway, heart rate, and infrared thermography while valenced images were shown to participants. Ninety-two participants were recruited from the University of North Florida and participants were …

Sedative Hypnotic Medications: Effect On Negative Cognition And Insomnia, Austin L. Larsen

Theses and Graduate Projects

The pursuit of healthy sleep in the United States often involves the use of prescription medications that were never intended for long-term treatment of insomnia. The use of medication to address sleep difficulty has multiple sources, including the medical system and a consumer driven economy within the United States. Behavioral interventions for insomnia have been increasing in availability and effectiveness over time, but medication use continues to be a first-line treatment for sleep problems. The focus of the current paper is the exploration of relationships between sedative use, sleep difficulties, and negative cognition in a sample of 104 adult participants …

Behavioral Markers And Endophenotypes Underlying Individual Differences In Ethanol Use, Haily R. Knapp

Honors Theses and Capstones

The main concern of this study is to evaluate the neurobiology of ethanol self-administration and cue-induced reinstatement in rats and its implications for Alcohol Use Disorder (AUD) prevention and treatment. The purpose of this study is to use a pre-clinical model of ethanol use to understand the individual effects at the neurobiological level. The study utilized economic demand and negative consequence testing to evaluate the rats' motivation to consume ethanol and their ability to relapse after periods of abstinence. The results showed individual and sex differences in ethanol consumption, with rats who placed a higher value on ethanol being more …

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 …

The Influence Of Early Childhood Parental Feeding Behaviors On Self-Regulation & Food Decision-Making In Young Adults, Natasha Singareddy

CMC Senior Theses

This study used data from a diverse set of undergraduates from the Claremont Colleges to examine the relationship between cognitive control (impulsivity and response inhibition) and self-regulatory ability as an indicator of sustained early childhood parental feeding behaviors in adulthood. In addition, the current study explored if early childhood parental feeding behaviors predicted food decision-making in adulthood as a result of perceived taste and nutritional value of food items. It was hypothesized that heightened impulsivity and impaired response inhibition as measures of cognitive control would correlate to poorer self-regulation, in turn reflecting a particular mode of early childhood parental feeding …
