Subconcussive Impacts And Their Effect On Attention, Scott York

Masters Theses & Specialist Projects

In recent years, concussions have become a focal point for athletic competition and athletes beginning in grade school. The long-term implications of concussions are becoming more widely known and accepted; however, there are still areas of literature that are lacking. One of these areas is subconcussive impacts. Subconcussive impacts are defined as impacts that do not meet the threshold for diagnosed concussion but may still have clinical impact. While concussions and their effects on cognition have been examined heavily, these subconcussive impacts, and their effects, have been studied less so. The purpose of this study is to examine the possible …

Observing Dynamic Emotional Faces From Many Generations, Tashaunda Grimmett

Masters Theses & Specialist Projects

This study sought to further understand emotion perception capabilities in younger and older adults. Previous studies examining emotion perception have consistently found emotion recognition deficits with age. The most common technique used to investigate age differences in emotion perception is a label selection task that presents static images of actors expressing emotion. More recently, dynamic stimuli have been developed; they portray realistic facial expressions that are more comparable to what one sees in real life. The use of dynamic stimuli has been found to ameliorate most age differences in the recognition of basic emotion categories. The current study presented dynamic …

Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna

Electronic Theses, Projects, and Dissertations

In Parkinson’s Disease (PD), research has shifted to investigate how biomarkers commonly seen in Alzheimer’s Disease (AD), such as amyloid beta (AB), may be associated with cognitive functioning in PD. AB is considered a reliable biomarker for AD pathology, however in PD there is a lacking biomarker that can accurately reflect severity of cognitive impairment. AD research has shown an association between low AB and cognitive decline, but the data in PD has mixed results. Most studies that analyze cognitive decline and biomarkers do not use a cutoff level and the few that do have a threshold vary greatly in …

Driving Healthy Behaviors Through Social Support: The Role Of Co-Responsibility In Weight Loss And Maintenance, Melanie Knufinke-Meyfroyt, Carlo Lancia, Yentl Lodewijks, Simon Nienhuijs, Eva Deckers

Patient Experience Journal

Objective: The effectiveness of out of hospital lifestyle interventions in healthcare is likely co-dependent on social support from involved one's. We sought to investigate the interrelationships between patient-partner Co-responsibility, Spousal Support, and Self-efficacy and the mechanisms through which they contribute to health behaviors and outcomes relevant to weight loss and maintenance. Methods: Co-responsibility, Spousal Support, self-efficacy, health outcomes and health behaviors like total weight loss, physical activity, OBESI-Q, and health satisfaction were assessed through a questionnaire among 868 individuals attempting to lose weight. Full and semi-partial correlations were used to understand the association between Co-responsibility, Spousal Support, Self-efficacy …

Fear, Distress, And Dissociation: Correlates Of Physiological Hyporeactivity After Interpersonal Victimization, Natalia Kecala

Dissertations

Background and Objective: Despite consistent findings of high reactivity to trauma cues in PTSD, there exists a consistent subset of physiological nonresponders who exhibit more complex and severe posttraumatic symptomatology. Research has identified different patterns of defensive reactivity representing Fear (core) and Distress (complex) PTSD symptoms. However, no studies have directly compared responders and nonresponders on physiological and clinical symptoms posttrauma.

Method: 66 adult women who had experienced first-degree sexual or physical assault within the last month were categorized using heart rate reactivity (HRR) to two personalized trauma scripts. Participants exhibiting negative HRR to both scripts were classified as nonresponders …

Psychophysical And Pharmacological Models Of Visual Hallucination, Nathan H. Heller

Dartmouth College Ph.D Dissertations

Visual hallucinations are visual experiences that are spontaneously generated by the brain, in the absence of appropriate external stimuli. Understanding the neural processes that give rise to these experiences is a complex challenge that spans the domains of psychology, neuroscience, and clinical practice. Model hallucinations can serve as a valuable tool in this context. They allow researchers to study hallucinatory experiences under controlled conditions, thus providing insights into their behavioral and neural underpinnings, which can facilitate the development of effective treatments. By creating models that emulate different aspects of hallucinatory experience, whether through pharmacological means, sensory manipulation, or cognitive tasks, …

Resting-State Eeg Microstate Features For Major Depressive Disorder Classification, George M. V. Quinn

Dissertations, Theses, and Capstone Projects

Neuroimaging studies have revealed consistent abnormalities in functional connectivity within specific neural networks that may serve as biomarkers for major depressive disorder (MDD). It is important to find inexpensive, non-invasive techniques that target these biomarkers to make diagnosis easier and more objective. EEG microstates are quasi-stable potential topographies that are thought to reflect the quasi-stable network activity of the underlying neural generators. MDD has been shown to alter features of the four canonical EEG microstates (A, B, C, D) with some conflicting results. The most consistent network abnormalities in MDD are found in the anterior default mode network, and this …

High Beta Brainwaves And Emotion Dysregulation In A Sample Of Children With Attention Deficit/Hyperactivity Disorder, Rebecca Carr

Theses and Graduate Projects

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity. The current study investigated the relationship between high beta brain wave activity, anxiety, emotion dysregulation, and comorbid mental health diagnoses in children with ADHD. Utilizing archival data from the Clinic for Attention, Learning, and Memory (CALM) in Minneapolis, MN, the study included 184 participants aged 6-14 years who underwent quantitative electroencephalogram (qEEG) assessments. The study utilized linear and logistic regressions to test three hypotheses: whether high beta activity predicted (1) increased anxiety symptoms, (2) emotion dysregulation, and (3) the likelihood of comorbid mental health …

Serotonin 1a Receptor Modulation On Behavioral Flexibility In Btbr And C57bl/6j Mice, Cassandra Cavazos

Electronic Theses, Projects, and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by a subset of symptoms known as restricted repetitive behaviors (RRBs). RRBs are categorized into both lower order and higher order RRBs, where the latter can be described as behavioral inflexibility. The BTBR T+ tf/J (BTBR) mouse strain has been an extensively used animal model that demonstrate the behavioral symptoms of these individuals, including inflexible behavior. Currently, there are few effective treatments for individuals with ASD that express RRBs. Past research has investigated treatments that target serotonin due its historic involvement in ASD. 8-OH-DPAT (8-hydroxy-2-(di-n-propylamine) tetralin) is a research …

The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson

Electronic Theses, Projects, and Dissertations

The focus on serotonergic dysfunction as a contributor to cognitive deficits in disorders such as autism spectrum disorder, Alzheimer's disease, and schizophrenia drives researchers to investigate the functional impact of specific serotonin receptor types on executive functioning. By discerning the potential enhancement or impairment effects, this endeavor seeks to unravel the complex interplay between serotonin receptors and cognitive abilities. Specifically, within the three domains of learning, acquisition, consolidation, and retrieval, we find serotonergic modulation to be pivotal. Recent studies have highlighted the 5-HT6 receptor as a novel target for cognitive enhancement. However, the majority of the research investigates the effects …

Alcohol And The Resulting Consequences Of Delirium Tremens, Nicasio L. Santos

2024 Symposium

Alcohol is a depressant drug, inhibiting the function of the central nervous system (CNS) and neurons in the mind (Greenberg, 1953). This results in physiological effects that are typical of an inhibited CNS; slowing of the heartbeat and breathing, and decreasing blood pressure (Scorzelli & Chaudhry, 2009). However, this inhibition of both the CNS and the neural chemistry develops a tolerance, and in turn withdrawal symptoms (Polli et al., 2023). These withdrawal symptoms are the inverse of the inhibition caused by the depressant effects of alcohol (i.e., an overactive CNS, increased activity of neurons; Smith-Alnimer & Watford, 2004). In extreme …

The Blessed Assembly: Irreplaceable Physical Co-Presence In Worship And Healthy Hybridity Reimagined After The Pandemic In The Digital Age, Yvette, Ying Wai Lau

Doctor of Pastoral Music Projects and Theses

Because of the unprecedented and unexpected force of the pandemic since 2020, most churches around the world have experienced some online worship during the lockdown of their cities or the mandated closure of the church buildings. For many people, online worship seems to be an equivalent, if not better, alternative for gathering together—a physical co-presence in worship—even after the pandemic has ended. As necessary and vital as online worship experiences have been for Christians during the pandemic, the witness of the church from Pentecost throughout Christian history indicates that gathered worship in physical spaces is irreplaceable for faith formation and …

Poland Syndrome And The Sensorimotor Cortex: An Untapped Possibility For Research, Ace Laikind

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Poland syndrome is a rare disorder that unilaterally affects the chest, arms, and hands. Despite being a limb disorder, there has not been research done on how Poland syndrome interacts with the sensorimotor cortex. Other limb disorders have documented connections to the sensorimotor cortex, and can be used to infer how Poland syndrome affects the sensorimotor cortex. Limb disorders with extensive research on the sensorimotor cortex are phantom limb syndrome, focal hand dystonia, and congenital one-handedness. Additionally, to accommodate for the confound created by the differences between congenital and acquired conditions, blindness and its effects on plasticity can be examined. …

The Relationship Between Rejection Sensitivity And Higher Order Cognitive Functions, Rachel Gaynor

USF Tampa Graduate Theses and Dissertations

Rejection sensitivity indexes individual differences in the expectation of, reaction to, and interpretation of possible rejection. Research on mechanisms underlying these individual differences have identified a reduction in top-down emotion regulatory processes in those exhibiting heightened rejection sensitivity. Most of these studies utilize rejection-specific affective stimuli. This study examined the relationship between rejection sensitivity score, calculated from the 18-question RSQ, and the recruitment of higher level inhibition resources, as indexed by the conflict N2, on three novel Flanker tasks. In order to further examine previously identified patterns in affective inhibition across differing levels of rejection sensitivity, and to determine whether …

An Epigenetically Driven Relationship Between Parental Ptsd And Inflammatory Disease In Offspring: A Proposal, Emma Griffith, Kevin P. Kaut

Journal of Neuropsychology and Behavioral Processes

Could a combat veteran's horrific experiences in early-2000s Afghanistan have a direct, biological impact on his or her now-adult daughter's risk of a heart attack later in her life? This concept would have been unapologetically mocked a mere twenty years ago, and it has only been in the past decade that the new field of epigenetics has revealed a distinct possibility for this event to actually take place—for parents' experiences to profoundly influence the biology of their children. The major objective of this research project is to argue for the legitimacy of this theoretical phenomenon by discussing the latest data …

Pre-Stimulus Anticipation And Unconscious Fear Learning Disparities In Individuals With Varying Levels Of Anxiety, Anastasiya Rumyantseva Kharlamova

Dissertations, Theses, and Capstone Projects

The current study employed a Pavlovian conditioning paradigm to investigate the influence of pre-stimulus unconscious threat anticipation on subsequent fear responses in associative learning. Additionally, we explored the differences in pre-stimulus anticipation among individuals with varying levels of anxiety. Electrodermal response (EDA) was chosen as a primary measure due to its robustness in fear conditioning paradigms. Moreover, the State-Trait Anxiety Inventory (STAI) was utilized to assess anxiety levels in participants. Twenty-seven subjects were recruited to determine if pre-stimulus skin conductance responses (SCR) would exhibit stimulus-specific patterns influenced by implicit cues (L-shaped configurations) that indicated an upcoming face or a house …

Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus

Research Collection School of Social Sciences

Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, …
