The role of peripheral physiology in the experience of emotion has been debated since the 19th century following the seminal proposal by William James that somatic responses to stimuli determine subjective emotion. Subsequent views have integrated the forebrain's ability to initiate, represent and simulate such physiological events. Modern affective neuroscience envisions an interacting network of "bottom-up" and "top-down" signaling in which the peripheral (PNS) and central nervous systems both receive and generate the experience of emotion. "Feelings" serves as a term for the perception of these physical changes whether emanating from actual somatic events or from the brain's representation of …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

Estimating Cognitive Workload In An Interactive Virtual Reality Environment Using Electrophysiological And Kinematic Activity, Christoph Tremmel

Biomedical Engineering Theses & Dissertations

As virtual reality (VR) technology continues to gain prominence in commercial, educational, recreational and research applications, there is increasing interest in incorporating physiological sensors in VR devices for passive user-state monitoring to eventually increase the sense of immersion. By recording physiological signals such as the electroencephalogram (EEG), electromyography (EMG) or kinematic parameters during the use of a VR device, the user’s interactions in the virtual environment could be adapted in real time based on the user’s cognitive state. This dissertation evaluates the feasibility of passively monitoring cognitive workload via electrophysiological and kinematic activity while performing a classical n-back task in …

Somatics Research Bibliography: A Working Tool For Somatics And Somatic Psychology, Eleanor Criswell Hanna

International Journal of Transpersonal Studies Advance Publication Archive

Many years ago when Somatics magazine was young, it occurred to me that it would be valuable to collect and publish research article references in Somatics magazine that were relevant to the different somatics disciplines to encourage the development of the field. There were next to no studies devoted to Somatics itself, but there were many studies devoted to the elements of somatic practices. Somatics is a multidisciplinary field. It builds on the research findings from many fields, such as anatomy, physiology, neurophysiology, psychology, dance, biomechanics, and education. The references are selected to be suggestive to the interested researcher and …

Child Psychological Maltreatment, Alison Boughn

Dissertations and Theses

Child psychological maltreatment (PM) is challenging to define and difficult for a child to articulate. This study introduces the development and initial implementation of the Psychological Maltreatment Inventory (PMI) with child participants. The PMI consists of 16 items validated by subject matter experts. The pilot study sample (N = 21) and large sample (N = 166) consisted of child participants currently involved in open child maltreatment cases at a Child Advocacy Center (CAC) in the Midwest. Quantitative research was used to explore the descriptive characteristics of the PMI to participant demographic information and correlational design to explore the relationship between …

Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna

Electronic Theses and Dissertations

Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social …

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 …

Effects Of Canines On Humans' Physiological And Perceived Stress, Beth Marie Bowin

Walden Dissertations and Doctoral Studies

The bond between pet and owner has been shown to decrease stress-related physical, mental, and emotional disorders by lowering blood pressure and heart rate. The purpose of this study was to examine whether a nonpet canine would have the same effect in reducing physical symptoms of stress as a known dog. Human-animal bond theory, Human pressor test. Data were analyzed using repeated measures, analyses of variance, and t tests. Results indicated that interaction with a strange dog lowered heart rate and blood pressure significantly faster in the experimental group than in the control group. The positive social change implications of …

Bridging Act-R And Project Malmo, Developing Models Of Behavior In Complex Environments, David M. Schwartz

Honors Theses

Cognitive architectures such as ACT-R provide a system for simulating the mind and human behavior. On their own they model decision making of an isolated agent. However, applying a cognitive architecture to a complex environment yields more interesting results about how people make decisions in more realistic scenarios. Furthermore, cognitive architectures enable researchers to study human behavior in dangerous tasks which cannot be tested because they would harm participants. Nonetheless, these architectures aren’t commonly applied to such environments as they don’t come with one. It is left to the researcher to develop a task environment for their model. The difficulty …

Driving Anxiety In Young People With Autism Spectrum Disorder : A Driving Simulator Pilot Study, Rebecca Pasch

Honors Theses

The goal of this project was to investigate how driving anxiety changes overtime in young people with autism spectrum disorder (ASD) when using a driving simulator technology. Additional exploratory measures were collected on duration of participation,. stopping distance, and reaction time.

If A Virtual Tree Falls In A Simulated Forest, Is The Sound Restorative? An Examination Of The Role Of Level Of Immersion In The Restorative Capacity Of Virtual Nature Environments, Jessica Michaelis

Electronic Theses and Dissertations

Stress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students …

When Empathy Only Goes So Far: Development Of A Trait Parochial Empathy Scale, Anna Maria C. Behler

Theses and Dissertations

Empathy, the ability to feel and/or understand another’s emotional state, plays a significant role in interpersonal interactions, mitigating hostility and enhancing affiliation and helping. However, empathy also biases interpersonal reactions. For example, at the group level empathy can become amplified towards members of their ingroup and blunted towards individuals in outgroups, a term called parochial empathy. Currently, no validated measures of parochial empathy at the dispositional level exist, and development of such a scale would be important to understanding the role of group-based emotions in prejudice and discrimination against outgroups. I conducted five studies to develop and validate a …

Expectations For Dog Ownership: Perceived Physical, Mental And Psychosocial Health Consequences Among Prospective Adopters, Lauren Powell, Debbie Chia, Paul Mcgreevy, Anthony L. Podberscek, Kate M. Edwards, Brendon Neilly, Adam J. Guastella, Vanessa Lee, Emmanuel Stamatakis

Human-Companion Animal Relationships Collection

Dog ownership is popular worldwide, with most human-dog dyads forming successful attachment bonds. However, millions of dogs are surrendered to animal shelters annually, possibly due to mismatches between owner expectations and the realities of dog ownership. The aim of the current study was to explore the benefits and challenges people expect from dog ownership and how these expectations vary with previous ownership history. An Australian-wide sample of 3465 prospective adopters completed a self-administered online questionnaire about the physical, mental and psychosocial health benefits and challenges they associated with dog ownership. Among the potential benefits, respondents expected increased walking (89%), happiness …

Acute Salivary Cortisol Response Among Mexican American Adolescents In Immigrant Families, Su Yeong Kim, Minyu Zhang, Katharine H. Zeiders, Lester Sim, Marci E. J. Gleason

Research Collection School of Social Sciences

Objectives: Though previous research has indicated that language brokering can be stressful, the findings are mixed, pointing to potential moderators of the association. Guided by an ecological perspective, we examined the role of individual, family, and environmental factors in Mexican American adolescents’ acute cortisol responses to language brokering. Method: The study consisted of 46 Mexican American adolescents recruited around a metropolitan city in Central Texas. Participants translated a difficult medical document from English to Spanish for their parents, followed by an arithmetic task (modeled after the Trier Social Stress Test [TSST]). Participants’ perceptions (perceived efficacy and parental dependence), parental hostility, …

Towards A Physio-Cognitive Model Of Slow-Breathing, Chris Dancy

Faculty Conference Papers and Presentations

How may controlled breathing be beneficial, or detrimental to behavior? Computational process models are useful to specify the potential mechanisms that lead to behavioral adaptation during different breathing exercises. We present a physio-cognitive model of slow breathing implemented within a hybrid cognitive architecture, ACT-R/Φ. Comparisons to data from an experiment indicate that the physiological mechanisms are operating in a manner that is consistent with actual human function. The presented computational model provides predictions of ways that controlled breathing interacts with mechanisms of arousal to mediate cognitive behavior. The increasing use of breathing techniques to counteract effects of stressors makes it …

Towards A Physio-Cognitive Model Of The Exploration Exploitation Trade-Off., David M. Schwartz, Christopher L. Dancy

Faculty Conference Papers and Presentations

Managing the exploration vs exploitation trade-off is an important part of our everyday lives. It occurs in minor decisions such as choosing what music to listen to as well as major decisions, such as picking a research direction to pursue. The dilemma is the same despite the context: does one exploit the environment, using current knowledge to acquire a satisfactory solution, or explore other options and potentially find a better answer. An accurate cognitive model must be able to handle this trade-off because of the importance it plays in our lives. We are developing physio-cognitive models to better understand how …

Psychophysiology Meets Computer Science: Predicting The Magnitude Of Participant Physiological Response With Machine Learning, Avonie Parchment

Electronic Theses and Dissertations

The present inquiry uses methods from psychophysiology and machine learning to reduce overall error in classification models. The field of psychophysiology, though rooted in decades of experimentation, has never reached the same level of precision as some aspects of medical inquiry. In fact, while some medical regression models, when determining some way to classify a patient's illness based on certain symptoms, can result in highly significant results with large effect sizes, equal levels are virtually unheard of in psychophysiology. The present investigation attempts to unravel some part of this mystery and determines some possible reasons for the difficulty in finding …

Effects Of Lighting And Noise On Performance And Situation Awareness In Air Traffic Control Tasks, Saralee Pruksaritanon

Student Works

Work environment influences an individual’s performance and situation awareness (SA). This study aims to investigate the effects of lighting and noise on the performance and SA in air traffic control (ATC) tasks. These two variables are important in the domain of ATC because the tasks require an individual to receive and process information both visually and auditorily. The results are useful for designing air traffic control rooms, which are set differently among different air navigation service providers. The subjects are 16 students majoring in Air Traffic Management (ATM) at Embry-Riddle Aeronautical University (ERAU) – Daytona Beach, FL. The research uses …

Ample Evidence For Fish Sentience And Pain, Lynne U. Sneddon, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Donald M. Broom, Culum Brown

Animal Sentience

The majority of commentaries are supportive of our position on the scepticism that muddies the waters surrounding fish pain and sentience. There is substantial empirical evidence for pain in fish. Animals’ experience of pain cannot be compared to artificial intelligence (AI) because AI can only mimic responses to nociceptive input on the basis of human observations and programming. Accepting that fish are sentient would not be detrimental to the industries reliant on fish. A more proactive discussion between scientists and stakeholders is needed to improve fish welfare for the benefit of all.

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 …

How Socioeconomic Disadvantages Get Under The Skin And Into The Brain To Influence Health Development Across The Lifespan, Pilyoung Kim, Gary W. Evans, Edith Chen, Gregory Miller, Teresa Seeman

Psychology: Faculty Scholarship

Socioeconomic disadvantage (SED) has adverse impacts on physical (Adler and Rehkopf 2008; Blair and Raver 2012; Braverman and Egerter 2008; Cohen et al. 2010; Poulton et al. 2002) and psychological (Adler and Rehkopf 2008; Bradley and Corwyn 2002; Grant et al. 2003) health development. SED is similar to low socioeconomic status (SES) which is based on occupation, income, and education or a composite of more than one of these indicators (McLoyd 1998). However, we conceptualize SED more broadly than socioeconomic status to also include subjective perception of social position and contextual indicators of disadvantage, such as neighborhood deprivation. One of …

Spirituality Within Reach: A Pathway Through Meditation, Serena C. Cyr

Antioch University Dissertations & Theses

Meditation is an ancient spiritual practice that has been demonstrated to be beneficial in reducing chronic pain, substance use, and eating disorders, as well as aiding in the treatment of sleep disorders, cancer, and psychological distress. In an effort to enhance the benefits, many contemporary meditation practices have been secularized, focusing on the cognitive, the psychological, and the emotional components, while de-emphasizing the spiritual aspects of meditation. However, spiritual meditation practices also demonstrate benefits, including stress reduction, improved emotional well being, increases in pain tolerance, reductions in mental health symptoms, and increased faith. However, little is known regarding the effects …

Evidence Of Youthful Aging: Chronic Stress And The Association With Dna Damage, Jason M. Fly, M. Catherine Desoto

McNair Scholars Program Summer Research Symposium

Abstract: Persistent elevated basal levels of the hormone cortisol are an indication of chronic stress. Maladaptive response to stress, or chronic psychological stress, is thought to play a crucial role in the biological mechanisms involved in mental disorders, disease, and accelerated aging. In 2011, a critical connection was reported between elevated cortisol and the oxidative damage to DNA associated with aging and disease in a study of elderly participants (ages 63-83) via 24-hour urinary samples (Joergensen, et. al., 2011). This connection, if verified, has implications for how stress may accelerate the aging process and the onset of cancer, diabetes, and …

Lived Experiences Of African American Males With Fibromyalgia, Ethel Denise Perry

Walden Dissertations and Doctoral Studies

Fibromyalgia (FM) is a musculoskeletal and neurological disorder that causes constant pain, cognitive problems with short term memory, and sleep disorders. There are more females diagnosed with FM than males, and research has therefore primarily been conducted with females. Because little is known about African American males with FM, biopsychosocial theory was used in this phenomenological study to examine how African American males with FM are affected biologically, psychologically, and socially. Eight African American males diagnosed with FM were recruited from Houston, Texas and were interviewed about their lived experiences with FM, including experiences with the healthcare system, and how …

We Still Need A Theory, Paula Droege

Animal Sentience

Woodruff (2017) has compiled a convincing array of data to support his contention that teleost fish feel pain. However, in the absence of an explanatory theory about the nature and function of consciousness, a checklist of criteria is insufficient to allay skeptical concerns. I offer a theory that can explain why features like selective attention and behavioral flexibility indicate consciousness. Consciousness represents the present moment in order to allow dynamic changes in actions or goals in response to situational demands.

Iraqi Refugees And Cultural Humility: A Mental Health Professional Training Program, Megan Brunmier Marsh

Antioch University Dissertations & Theses

This paper describes the development of a thorough nine-hour professional training program targeting the cultural humility of mental health clinicians who are treating new Iraqi refugee communities. I used the 15-step evidence-based Comprehensive Program Development Model created by Calley (2009) for the design of the structure, curriculum, and materials for this proposed program (Calley, 2011). The training program is informed by conceptual frameworks of cultural competence and humility, ecological systems theory, and social justice with goals of (a) exploring clinicians’ cultural attitudes in order to improve self-awareness at multiple levels (e.g., physiological, psychological, interpersonal), (b) increasing clinicians’ knowledge about Iraqi …

Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Mandy Walsh Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examined the effects of sex and type of partner infidelity, including both physical (i.e., sexually involved with another person) and emotional (i.e., emotionally involved with another person) infidelity, on mate abandonment behaviors. Previous research has demonstrated sex differences in emotional responses to infidelity, where men react more negatively to physical infidelity and women react more negatively to emotional infidelity. While various studies have investigated perceived behavioral reactions using imagined scenarios, this study expands current research by utilizing actual retrospective reports. It was hypothesized that males would engage in significantly more mate abandonment behaviors after experiencing a physical infidelity, …

Distress, Circadian Rhythms, Immunity, And Survival In Presurgical Breast Cancer Patients., Whitney Nicole Rebholz

Electronic Theses and Dissertations

Women with breast cancer experience significant stress related to diagnosis and treatment, which may negatively affect physiology (e.g., circadian, endocrine, and immune) and contribute to cancer progression. Demographic (e.g., ethnic minority) and neighborhood factors can contribute to cancer-related stress. African American women with breast cancer experience more adverse disease pathology and earlier mortality; however, factors that explain these disparities rarely have been explored. It is hypothesized that psychosocial stressors (i.e., ethnicity, neighborhood stress, and cancerrelated stress) will be related to one another. Associations of psychosocial stress with physiological disruption are posited with regard to circadian, endocrine, and immune function. It …
