Despite progress in understanding the social neuroendocrinology of close relationship processes, most work has focused on negative experiences, such as relationship conflict or stress. As a result, much less is known about the neuroendocrine implications of positive, emotionally intimate relationship experiences. In the current study, we randomly assigned 105 dating or married couples to a 30-minute semi-structured discussion task that was designed to elicit either high or low levels of closeness. Participants provided pre- and post-task saliva samples (to assess cortisol and testosterone) and post-task reports of self-disclosure, closeness, attraction, positive and negative affect, and stress. Participants found the discussion …

The Relationship Between Infant-Family Routines, Number Of Caregivers And Infant Basal Cortisol, Vanessa Newell, Hannah B. White
Undergraduate Research Symposium
Background: Family routines have been found to be related to child adjustment, marital satisfaction, and parenting competence (Fiese, 2002). Persistent stress, and the resulting frequent activation of the body’s stress responses, can result in excessive wear-and-tear on the body and brain known as allostatic load (McEwen, 2000). In infants, basal cortisol levels act as an instrument to measure allostatic load (White, 2020). To our knowledge, no existing work on the impact of routines on infant development has examined the role of family structure. In traditional and minority cultures it is common for caregiving responsibilities to be divided among multiple individuals. …

A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab
Dissertations, Theses, and Capstone Projects
Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …
Preclinical Behavioral Assessment Of Chronic, Intermittent Low-Dose Psilocybin In Rodent Models Of Depression And Anxiety,

Preclinical Behavioral Assessment Of Chronic, Intermittent Low-Dose Psilocybin In Rodent Models Of Depression And Anxiety, Harmony I. Risca
Dissertations
Recent studies have demonstrated the clinical efficacy of psychedelic-assisted psychotherapy for treatment-resistant depression and anxiety. Amidst the overall success of recent clinical trials using a single high dose of psilocybin, anecdotal reports indicate anxiolytic and antidepressant effects following a repeated low dose regimen. As therapeutic outcomes are often tightly intertwined with the individual’s subjective experience, animal models are used as objective measures to investigate the underlying mechanisms responsible for the putative antidepressant/anxiolytic effects of psychedelics. Three rodent models predictive of anxiolytic or antidepressant effects were used to evaluate effects of chronic intermittent low dose (CILD) psilocybin treatment; the Light/Dark conflict …

Is Pristine Inner Experience Linked To Biology? An Examination Of Experience Across The Menstrual Cycle Among Women With Premenstrual Distress, Alek E. Krumm
UNLV Theses, Dissertations, Professional Papers, and Capstones
The link between mind and biology is intuitively known: We notice changes in our mood and behavior when hungry, in pain, or under the influence of substances. Yet, the specifics of this link—for example, how changes in biology affect directly apprehended conscious experience— are not well known. The present study was an exploratory attempt toward filling that gap by using a state-of-the-art, beeper-driven method for exploring directly apprehended conscious experience (Descriptive Experience Sampling; DES) across one of the most predictable and wellknown biological cycles: menstruation. We screened approximately 300 college women to identify those who reported clinically significant symptoms of …

Serotonin 1b/1a Receptor Modulation On Behavioral Flexibility In C57bl/6j Mice, Brandon L. Oliver
Electronic Theses, Projects, and Dissertations
Pharmacological activation of the 5-HT1B and 1A receptors has been implicated in OCD-like behaviors in rodents such as increased perseverative circling, checking behaviors, and locomotor stereotypy. However, little is understood about the effects of 5-HT1B and 1A receptor activation on behavioral inflexibility, a common symptom associated with OCD. The present study utilized the 5-HT1B/1A receptor agonist RU24969 at 0.01, 0.1, and 1.0 mg/kg to test three hypotheses. The first hypothesis predicted RU24969 would lead to a dose-dependent impairment on behavioral flexibility in C57BL/6J mice. It was also predicted that male C57BL/6J mice would be more inflexible than female C57BL/6J mice …

Exploration Of Patient Variables And Characteristics Best Suited For Medical Marijuana Treatment For Anxiety And Depressive Disorders, Corey Gazoo
Dissertations
Individuals with posttraumatic stress, anxiety and depressive disorders are currently being prescribed medical marijuana as a treatment in many states across the United States. However, marijuana is still considered a schedule one narcotic by the Drug Enforcement Administration and federal government, which provides several barriers and challenges to conduct research such as approval from the U.S. Food and Drug Administration and following guidelines from the National Institute on Drug Abuse issued by the DEA. Additionally, individuals prescribed medical marijuana for mental health disorders are not always thoroughly instructed on the type of medical marijuana, the dosage, and how frequently to …

Medication Versus Brain-Based Treatment: Evaluation Treatment Preferences Of Parents Of Children With Adhd, Rebecca Recio-Swift
Electronic Theses and Dissertations
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental disorders across the world. Currently, treatment for ADHD mostly consists of either medication or behavioral therapy or a combination of both. However, research has shown that medication used as therapy for the treatment of ADHD has side effects which parents deem undesirable for their children. Therefore, recent research has focused on patient and parent preferences. Studies have found that behavioral or other treatment options may often be chosen over medications. These same studies have documented the characteristics of parents that prefer certain treatments for their children. The purpose of this …

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
All NMU Master's Theses
Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …

The Effect Of A Mindfulness-Based Intervention On Attention And Cognitive Control As A Function Of Smartphone Notifications., Joshua D. Upshaw
Graduate Theses and Dissertations
Barriers to accessing mobile technology, particularly smartphones, have decreased substantially since the iPhone’s release in 2007, resulting in increased ownership and usage across all ages, genders, and races. Despite their ubiquity in our society, relatively little empirical work has investigated the influence of smartphones on our higher order executive functioning. Prior work has linked smartphone use with impaired cognitive control during cognitively demanding tasks, especially in heavier smartphone users. The goals of the current study were twofold. First, the study aimed to examine the effects of smartphone notifications on cognitive control and attention. And second, to determine the effects of …

The Role Of Athletic Identity In General Mental Health And Alcohol-Related Help-Seeking Intentions Of College Students, Michael Grant Young
Psychology Theses & Dissertations
Young adults are vulnerable to a range of mental health concerns and tend to drink in high quantities and tend to not seek help for these concerns. Specifically, college students involved in athletics tend to have low help-seeking rates—though help-seeking research for this population is relatively limited. Athletic identity (i.e., identification with the athlete role) is a relevant construct for examining this population, however little is known about its association with help-seeking beliefs and ideas. This study examines: (1) the association between athletic identity and help-seeking intentions for both mental health and alcohol use concerns, (2) the association between …

Predicting Inattentional Blindness With Pupillary Response In A Simulated Flight Task, Kellie D. Kennedy
Psychology Theses & Dissertations
Inattentional blindness (IB) is the failure of observers to notice the presence of a clearly viewable but unexpected visual event when attentional resources are diverted elsewhere. Knowing when an operator is unable to respond or detect an unexpected event may help improve safety during task performance. Unfortunately, it is difficult to predict when such failures might occur. The current study was a secondary data analysis of data collected in the Human and Autonomous Vehicle Systems Laboratory at NASA Langley Research Center. Specifically, 60 subjects (29 male, with normal or corrected-to-normal vision, mean age of 34.5 years (SD = 13.3) were …

Delayed Modulation Of Glutamate Receptors By Anti-Epileptic Drugs After Traumatic Brain Injury In Rats, Edgar Rodriguez
Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) is a significant health concern. Around 74 million people sustain a traumatic brain injury worldwide. The damage caused by TBI produces two types of injury; primary and secondary injuries. Primary injury is caused within milliseconds and is irreversible. Secondary brain injury is delayed and produced by molecular, cellular, and structural disruption after the initial injury. One of the most devastating dysfunction after TBI is glutamate neurotransmitter overactivation that could lead to neurotoxic levels of glutamate in the brain (i.e., excitotoxicity). Excitotoxicity has been linked with the development of epilepsy after TBI, also known as post-traumatic epilepsy …

Dissertations, Theses, and Capstone Projects
Anxiety disorders are among the most common mental health diagnoses, affecting about a third of the population in their lifetime. However, approximately a third of individuals with anxiety do not respond to current treatment approaches, highlighting the need to identify additional potential therapeutic mechanisms. Safety learning is one such mechanism, but methodological challenges and a dearth of research have prevented the field from advancing the understanding of the role of safety learning in the etiology and remediation of anxiety disorders. Animal research, using single-cued safety learning paradigms, has yielded promising early findings, demonstrating that safety learning directly reduces anxiety-related behaviors …

Dissertations, Theses, and Capstone Projects
Research has helped to shed light on the functional organization and neural mechanisms of distractors on memory-guided saccades. In our current study we have utilized eye tracking and EEG technology to simultaneously record the changes in saccadic eye movement (SEM) behavior and event-related potentials (ERPs) associated with performance on a memory-guided saccade task with distractor conditions. Thirteen healthy control participants (n = 13; 6 female) were tasked to complete 864 memory-guided saccade trials with both visible (white) and invisible (black) distractors presented on a black background before saccade initiation. Compared with the control (black) distractor condition, distractor presentation produced a …

Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle
Dissertations, Theses, and Capstone Projects
Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …

Atypical Structural Neuroconnectivity Associated With Emotional Face Processing And Clinical Affect In Children With Chromosome 22q11.2 Deletion Syndrome, David Dodd Stephenson Jr
LSU New Orleans Theses and Dissertations
Schizophrenia spectrum disorder (SCZ) is a debilitating psychiatric disorder that affects approximately 1% of the general population. The etiopathology of this disorder is not fully understood with genetic and environmental factors underpinning vulnerability and disease progression. Children with chromosome 22q11.2 deletion syndrome (22q11.2DS) are at ultra-high risk for developing SCZ with 30% developing the disorder in adolescence or young adulthood. To investigate associations with psychosis vulnerability, much work has been performed looking at neurological underpinnings between schizophrenia and 22q11.2DS to assess similarities between both genetic and idiopathic forms of schizophrenia in adults. However, many past studies have assessed this using …
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality,

Brigham Young University
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter
Intuition: The BYU Undergraduate Journal of Psychology
Darwin offered an evolutionary perspective on the origins of human morality, suggesting that humans share a biological foundation with nonhuman primates. This paper reviews the current literature on moral and prosocial behaviors of nonhuman primates, specifically examining whether nonhuman primates exhibit behaviors that are typical of empathy and fairness. The literature documents that nonhuman primates exhibit empathetic behaviors regarding emotional contagion and sympathetic concern. There is also evidence that nonhuman primates have a sense of fairness, seen in their reciprocal behaviors and aversion to inequity. Taken together, this suggests that there are evolutionary roots of morality, lending empirical support to …
