Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Impact Of Childhood Trauma On Skin Conductance Response To Fear, Safety, And Reward, Tristan Alana Gregg

Master's Theses (2009 -)

Trauma is associated with neurological and physiological differences that can persist years after trauma exposure. Physiologically, trauma has been associated with altered responses to cues in the environment, most commonly threatening stimuli. For instance, in participants who experience trauma during adulthood, such individuals exhibit heightened physiological arousal. Conversely, other studies have found that childhood trauma may be associated with blunted physiological arousal. Most of this research has involved threatening cues, but previous research suggests that trauma is also associated with aberrant physiological arousal responses to positive or rewarding cues. Skin conductance responses (SCRs) are a commonly utilized measure of physiological …

Examining Women's Psychophysiological Responses Under Increasingly Obvious Sexism, Shelby Helwig

Electronic Theses and Dissertations

When women experience sexism, it may at first be subtle and difficult to label only becoming clearer over time. Sexism is often ambiguous in nature and experienced over an extended period; therefore, studying sexism as it occurs in daily life is crucial to extending our understanding of how women cope with discrimination. Past research has shown that women may experience maladaptive physiological responses when exposed to various forms of sexism. The current study investigated women’s cardiovascular reactivity and recovery responses to prolonged, increasingly obvious sexism. Women evaluated resumes in a mock search committee meeting with two male confederates whose statements …

Kindness In The Bardo: Empathy As A Catalyst For Healing In Victims Of Dissociation, Julia Dorothea Chopelas

Criterion: A Journal of Literary Criticism

In George Saunders’ Lincoln in the Bardo, a host of undead characters find themselves in a spiritual limbo based on the bardo. Although they won’t admit it to themselves, Roger Bevins III and Hans Vollman are most certainly dead. Despite their supernatural makeup as ghosts, Bevins and Vollman bear strong psychological resonance with the living: they are human, heartbroken, and lost. For the ghosts of Oak Hills Cemetery, the inefficient coping mechanism of dissociation perpetuates their afterlife imprisonment in the bardo. Bevins and Vollman suffer from a variety of dissociative symptoms, their minds’ psychological defense against the trauma that has …

Understanding Individual Differences Within Large-Scale Brain Networks Across Cognitive Contexts, Katherine L. Bottenhorn

FIU Electronic Theses and Dissertations

Historically, human neuroimaging has studied brain regions “activated” during behavior and how they differ between groups of people. This approach has improved our understanding of healthy and disordered brain function, but has two key shortcomings. First, focusing on brain activation restricts how we understand the brain, ignoring vital, behind-the-scenes processing. In the past decade, the focus has shifted to communication between brain regions, or connectivity, revealing networks that exhibit subtle, consistent differences across behaviors and diagnoses. Without activation-focused research’s constraints, connectivity-focused neuroimaging research more comprehensively assesses brain function. Second, focusing on group differences ignores substantial within-group heterogeneity and often imposes …

The Role Of Psychological Distress In Maintaining Exercise After Cancer Diagnosis, Patrick Tertulien

Walden Dissertations and Doctoral Studies

AbstractCancer affects the lives of thousands of people every day and is a leading cause of death. Exercise has been shown to yield mental and physical benefits for patients and survivors, but the experiences of cancer patients who face a multiplicity of psychological stressors have not been clearly described. The purpose of this qualitative study was to understand the psychological factors that are associated with continuing to exercise after cancer diagnosis, during and/or following their treatment. The focus was on how cancer survivors maintained a regular routine of exercise while experiencing psychological distress associated with cancer diagnosis, treatment, and concerns …

Physiological Measurements For Real-Time Fatigue Monitoring In Train Drivers: Review Of The State Of The Art And Reframing The Problem, Bojana Bjegojevic, Maria Chiara Leva, Nora Balfe, Sam D. Cromie, Luca Longo

Conference papers

The impact of fatigue on train drivers is one of the most important safety-critical issues in rail. It affects drivers’ performance, significantly contributing to railway incidents and accidents. To address the issue of real-time fatigue detection in drivers, most reliable and applicable psychophysiological indicators of fatigue need to be identified. Hence, this paper aims to examine and present the current state of the art in physiological measures for real-time fatigue monitoring that could be applied in the train driving context. Three groups of such measures are identified: EEG, eye-tracking and heart-rate measures. This is the first paper to provide the …

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez

CMC Senior Theses

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …

Commentary: Physiological And Psychological Impact Of Face Mask Usage During The Covid-19 Pandemic, Jennifer Scheid, Shannon Lupien, Gregory Scott Ford, Sarah West

Articles & Book Chapters

In this commentary, we discuss the physiological effects of wearing masks for prolonged periods of time, including special considerations, such as mask wearing among those who engage in exercise training, and concerns for individuals with pre-existing chronic diseases. In healthy populations, wearing a mask does not appear to cause any harmful physiological alterations, and the potentially life-saving benefits of wearing face masks seem to outweigh the documented discomforts (e.g. headaches). However, there continues to be controversy over mask wearing in the United States, even though wearing a mask appears to have only minor physiological drawbacks. While there are minimal physiological …

Relationship Between Humidity And Physiology In Warm And Humid Conditions – A Literature Review, Yuliya Dzyuban

Research Collection School of Social Sciences

Change in precipitation patterns caused by global warming will likely increase humidity in some areas of the world. Moreover, populations in tropical climates with already high humidity levels can experience an added stress on their health and thermal comfort due to an amplifying effect of heat and moisture. Humidity is a generic term commonly used to describe moisture in the air. However, there are numerous variables that describe different properties of humid air that can be used in scientific studies. While relative humidity remains the most used, it has several shortcomings associated with its high correlation with air temperature. Thus, …

Airway Hydrogen Peroxide During A Naturalistic Period Of Sustained Psychological Stress In Individuals With Asthma And Healthy Controls, Chelsey Werchan

Psychology Theses and Dissertations

Reactive oxygen species in the form of exhaled hydrogen peroxide (H₂O₂) and nitric oxide (NO) are important biological markers of inflammation and immune response in the airways of both asthmatics and healthy individuals. Previous research has linked psychological distress to changes in these processes in the airways, which can impact overall disease management outcomes. The current study examined changes in H₂O₂, NO, mood, and other physiological measures during times of prolonged stress using a naturalistic paradigm. Both healthy and asthmatic participants were assessed at three separate time periods; once during a low …

Parenting Style And Relational Aggression: The Moderating Role Of Physiological Reactivity, Maria Lent

Graduate College Dissertations and Theses

Low levels of physiological arousal in response to stress (e.g., low skin conductance level reactivity; SCLR) have long been conceptualized as a marker of fearlessness and a risk factor for physical aggression (e.g., hitting). Less is known, however, about how individual differences in children’s SCLR and early caregiving experiences interact to produce aggressive behavior. Preliminary evidence suggests that children with low SCLR may be at an increased risk of aggression in the context of highly negative or low positive parenting. Additionally, although most early parenting socialization research has focused on physical aggression, mounting evidence implicates parenting style in the development …

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 …

Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht

Theses and Dissertations

Upon returning from the first Gulf War, soldiers cited a plethora of unexplained physical and cognitive deficits which have since been termed Gulf War Illness (GWI). Presentation of GWI is positively correlated with pyridostigmine bromide (PB) use, which was prophylactically administered to soldiers in response to threats of chemical warfare. To test the overarching hypothesis that PB interacted with stress of deployment to alter neural, endocrine, and immune systems, the following studies used a 2×2 rodent model with 14 days of drug treatment (vehicle; PB) and 10 days of repeated restraint stress (stressed) or non-stressed-control conditions. Results indicate that PB …

Psychosocial Functioning And The Cortisol Awakening Response: Meta-Analysis, P-Curve Analysis, And Evaluation Of The Evidential Value In Existing Studies, Ian Andres Boggero, Camelia E. Hostinar, Eric A. Haak, Michael L. M. Murphy, Suzanne C. Segerstrom

Psychology Faculty Publications

Cortisol levels rise immediately after awakening and peak approximately 30-45 minutes thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and metaanalysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw …

Evaluation Of The Recreational Catch-And-Release Fishery For Golden Dorado Salminus Brasiliensis In Salta, Argentina: Implications For Conservation And Management, Tyler Gagne

Masters Theses

Golden dorado (Salminus brasiliensis, Cuvier, 1816) is increasing in popularity as a target for recreational anglers practicing catch-and-release (C&R) in northern Argentina and bordering countries. However, to date no research has looked at the potential social and ecological implications of growth in this recreational fishery. The first manuscript of this thesis assessed the consequences of C&R on golden dorado captured by anglers on the Juramento River in Salta, Argentina. This evaluation examined physical injury, physiological stress, reflex impairment, and short term post-release behavior to develop a clear set of evidence-based best practices for C&R. In addition, the Juramento …

Qualitative Behavioural Assessment And Quantitative Physiological Measurement Of Cattle Naïve And Habituated To Road Transport, C. A. Stockman, T. Collins, A. L. Barnes, D. Miller, S. L. Wickham, D. T. Beatty, D. Blache, F. Wemelsfelder, P. A. Fleming

Françoise Wemelsfelder, PhD

The present study examined whether observers could distinguish between cattle that are naïve to road transport and the same cattle after becoming more habituated to transport. The behavioural expression of cattle was assessed through the method of qualitative behavioural assessment (QBA), and these assessments were correlated with various physiological parameters. Fourteen Angus steers were assessed during their first road trip and then again on their ninth trip, 15 days later. Blood samples were collected immediately before and after transport, and heart rate and core body temperature were measured continuously throughout each trip. Video footage recorded during each trip was edited …

Bleeding Keaney Blue: An Analysis Of Sports Fandom And The Supporters Of Uri Basketball, Lia M. Moceri

Senior Honors Projects

In the United States, sports are so prevalent on the national, state, and local level that researchers assert they have become a major component of everyday life. In fact, millions of Americans consider themselves sports fans. Studying sports fandom offers an interesting insight into the human condition.

This paper begins by looking at sports fans on a psychological level by examining socialization, the process of becoming a sports fan. It also examines the reasons people become fans and the degree to which people identify as a fan. An important psychological aspect when studying sports fans is identity and how a …

The Influence Of Canine Aggression And Behavioral Treatment On Heart Rate Variability, Lydia Craig

Psychology Honors Projects

Dog aggression affects many, with nearly 5 million dog bites reported yearly in the United States alone. With the physical, emotional, and monetary costs of bites, it is of considerable interest to identify dogs that are likely to bite. One physiological measure that might serve as an index of aggression is heart rate variability (HRV), which refers to vagally mediated beat-to-beat change in heart rate. Low HRV has been associated with impaired emotional and behavioral regulation and stress in both humans and animals. To assess whether this measure corresponds with aggression in dogs, resting HRV was measured for dogs with …

Nature As A Buffer: The Physiological Effects Of Exposure To Nature On Stress, Tyler J. Stading, Jeffrey R. Stevens

UCARE Research Products

Exposure to images of nature following a stressful event can reduce physiological measures associated with stress. The objectives of this study was to determine whether exposure to nature before the stressor can buffer the stress response. We varied whether nature or urban images were viewed before or after a stressor and measured galvanic skin response in our participants. We describe how order of presenting the stressor influences nature’s calming effect on physiology.

Toddlers’ Word Learning From Contingent And Non-Contingent Video On Touchscreens, Heather L. Kirkorian, Koeun Choi, Tiffany A. Pempek

Psychology Faculty Scholarship

Researchers examined whether contingent experience using a touchscreen increased toddlers’ ability to learn a word from video. One-hundred-sixteen children (24-36 mos) watched an on-screen actress label an object: (1) without interacting, (2) with instructions to touch anywhere on the screen, or (3) with instructions to touch a specific spot (location of labeled object). The youngest children learned from contingent video in the absence of reciprocal interactions with a live social partner, but only when contingent video required specific responses that emphasized important information on the screen. Conversely, this condition appeared to disrupt learning by slightly older children who were otherwise …

Contemplating Mindfulness At Work: An Integrative Review, Christopher Lyddy, Darren J. Good, Theresa M. Glomb, Joyce E. Bono, Kirk W. Brown, Michelle K. Duffy, Ruth A. Baer, Judson A. Brewer, Sara W. Lazar

School of Business Faculty Publications

Mindfulness research activity is surging within organizational science. Emerging evidence across multiple fields suggests that mindfulness is fundamentally connected to many aspects of workplace functioning, but this knowledge base has not been systematically integrated to date. This review coalesces the burgeoning body of mindfulness scholarship into a framework to guide mainstream management research investigating a broad range of constructs. The framework identifies how mindfulness influences attention, with downstream effects on functional domains of cognition, emotion, behavior, and physiology. Ultimately, these domains impact key workplace outcomes, including performance, relationships, and well-being. Consideration of the evidence on mindfulness at work stimulates important …

Belief About Nicotine Selectively Modulates Value And Reward Prediction Error Signals In Smokers, Xiaosi Gu, Terry Lohrenz, Ramiro Salas, Philip R. Baldwin, Alireza Soltani

Dartmouth Scholarship

Little is known about how prior beliefs impact biophysically described processes in the presence of neuroactive drugs, which presents a profound challenge to the understanding of the mechanisms and treatments of addiction. We engineered smokers' prior beliefs about the presence of nicotine in a cigarette smoked before a functional magnetic resonance imaging session where subjects carried out a sequential choice task. Using a model-based approach, we show that smokers' beliefs about nicotine specifically modulated learning signals (value and reward prediction error) defined by a computational model of mesolimbic dopamine systems. Belief of "no nicotine in cigarette" (compared with "nicotine in …

Tractography Of The Spider Monkey (Ateles Geoffroyi) Corpus Callosum Using Diffusion Tensor Magnetic Resonance Imaging, D. Platas-Neri, S. Hidalgo-Tobón, B. De Celis Alonso, F. C-P De León, J. Muñoz-Delgado, Kimberley A. Phillips

Psychology Faculty Research

The objective of this research was to describe the organization, connectivity and microstructure of the corpus callosum of the spider monkey (Ateles geoffroyi). Non-invasive magnetic resonance imaging and diffusion-tensor imaging were obtained from three subjects using a 3T Philips scanner. We hypothesized that the arrangement of fibers in spider monkeys would be similar to that observed in other non-human primates. A repeated measure (n = 3) of fractional anisotropy values was obtained of each subject and for each callosal subdivision. Measurements of the diffusion properties of corpus callosum fibers exhibited a similar pattern to those reported in the …

Effects Of Dietary Preference On The Experience Of Anxiety, Depression And Acute Stress Response, Shaun Stearns

Theses and Dissertations

Research has demonstrated that high saturated fat and low carbohydrate consumption may provide physiological benefit in the treatment of major neurological disorders, though not much research has explored if these benefits extend to the experience of anxiety, depression, stress and physical symptoms. The purpose of this study was to explore the relationship between fat consumption and negative emotional/physiological states (anxiety, depression, stress and physical symptoms). This study also explored how fat consumption can alter one's response to an acute stress. Participants completed an online survey indicating their food preferences and their responses to a number of self-report scales such as …

Short-Term Changes In Responses To Stress In Runners, Molly Ann O'Connor

Theses and Dissertations

The use of physical activity to cope with stress is becoming increasingly popular. Research indicates that individuals who routinely engage in cardiovascular exercise report better overall physical and psychological health and reduced reactions to stress than those who do not. In addition, there may be short-term improvements for these individuals on days when they exercise. The current study was designed to examine short- and long-term differences between runners and non-runners. Cardiovascular, affective, and behavioral data were collected from runners over a two-day period that included a running day and a rest day, and over a similar period in a non-running …

Does Virtual Reality Elicit Physiological Arousal In Social Anxiety Disorder, Maryann Owens

Electronic Theses and Dissertations

The present study examined the ability of a Virtual Reality (VR) public speaking task to elicit physiological arousal in adults with SAD (n=25) and Controls (n=25). A behavioral assessment paradigm was employed to address three study objectives: (a) to determine whether the VR task can elicit significant increases in physiological response over baseline resting conditions (b) to determine if individuals with SAD have a greater increase from baseline levels of physiological and self-reported arousal during the in vivo speech task as opposed to the VR speech task and (c) to determine whether individuals with SAD experience greater changes in physiological …

Psychological Pathways Linking Social Support To Health Outcomes: A Visit With The “Ghosts” Of Research Past, Present, And Future, Wendy C. Birmingham, Bert N. Uchino, Kimberly Bowen, Mckenzie Carlisle

Faculty Publications

Contemporary models postulate the importance of psychological mechanisms linking perceived and received social support to physical health outcomes. In this review, we examine studies that directly tested the potential psychological mechanisms responsible for links between social support and health-relevant physiological processes (1980s to 2010). Inconsistent with existing theoretical models, no evidence was found that psychological mechanisms such as depression, perceived stress, and other affective processes are directly responsible for links between support and health. We discuss the importance of considering statistical/design issues, emerging conceptual perspectives, and limitations of our existing models for future research aimed at elucidating the psychological mechanisms …

Regional Gray Matter Correlates Of Perceived Emotional Intelligence, Nancy S. Koven, Robert M. Roth, Matthew A. Garlinghouse, Laura A. Flashman, Andrew J. Saykin

Dartmouth Scholarship

Coping with stressful life events requires a degree of skill in the ability to attend to, comprehend, label, communicate and regulate emotions. Individuals vary in the extent to which these skills are developed, with the term ‘alexithymia’ often applied in the clinical and personality literature to those individuals most compromised in these skills. Although a frontal lobe model of alexithymia is emerging, it is unclear whether such a model satisfactorily reflects brain-related patterns associated with perceived emotional intelligence at the facet level. To determine whether these trait meta-mood facets (ability to attend to, have clarity of and repair emotions) have …
