Developing A Coding System To Record Orofacial Movements For Misophonia With Verification From Physiology Data, Rachel P. Sellers

Senior Theses

My thesis aims to develop and evaluate a facial coding system that can quantify facial movements in the context of misophonia. The system uses binary coding to individually quantify and identify each orofacial movement that occurs independent of other movements or artifacts that could interfere with coding data. The system can be used across multiple coders with statistically significant reliability into how orofacial movements are interpreted. The psychophysiological verification study used electromyography to examine the muscle potentiation of the corrugator supercilii and zygomaticus major muscles to map observable facial movement to underlying muscle potentiation. This facial coding system can be …

Physiological Response To Concealed Information In A Mock-Crime Paradigm​, Ezra Koenigsberg, Tamya Mchenry, Jasmine Manzana, Taylor Powell, Samantha Jackson

Science University Research Symposium (SURS)

The Concealed Information Test (CIT), based on Lykken’s guilty knowledge framework, measures physiological responses when individuals recognize crime-related details compared to neutral alternatives. Previous studies show that variations in stimulus presentation enhance the CIT’s accuracy, especially through changes in electrodermal activity and heart rate. However, few studies have tested whether a Qualtrics-based mock-crime version of the CIT can replicate these physiological patterns. This study addresses that gap by adapting the CIT for a digital research environment. The goal is to determine whether participants show greater physiological arousal—measured through skin conductance, heart rate, and respiration—when exposed to crime-related “critical” stimuli compared …

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 …

You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler

Dissertations, Theses, and Capstone Projects

Humans have a fundamental need to form and maintain social connections, and thus experiencing social exclusion is extremely distressing as it threatens this basic human need. Individuals who are socially excluded often respond aggressively, not only towards their ostracizers but also towards innocent bystanders, with ostracism being implicated in extreme acts of violence such as school shootings. However, individual differences in behavior exist within the context of social exclusion as not everyone responds aggressively after being ostracized. Identifying risk factors for retaliatory aggressive behavior following experiences of social exclusion may facilitate the development of targeted interventions aimed at mitigating such …

A Theoretical Basis For Understanding And Researching The Relationship Between Music, Stress, And Biofeedback, Frederick Wang

Antioch University Dissertations & Theses

Music’s ability to influence emotional states and physical arousal has become an increasingly popular area of study. The wealth of literature around music and stress suggests a significant amount of interest in leveraging music to manage stress. However, as attention increases, the robustness of research becomes an increasing concern. This study investigates the current literature and proposes recommendations for the future studying of the psychological and physiological impacts of music as it relates to stress reduction. Existing literature was reviewed with a focus on the operationalization of key concepts of music and stress. The analysis showed considerable discrepancies in research …

Oxytocin, A Lover And A Fighter: Maternal Trauma Exposure And Mother-Child Coregulation, Patricia M. Pehme

Dissertations, Theses, and Capstone Projects

The placenta is responsible for regulating the fetal growth and environment in preparation for the anticipated external life. To succeed, it continuously adapts and weaves in a variety of neuroendocrine signals from the maternal organism. If a mother was exposed to trauma and her physiology sustained a change in the functioning of the immune, autonomic and/or endocrine systems, the placenta may anticipate different external environments for her children as compared to children of mothers without trauma exposure. This dissertation examined possible underlying mechanisms of psychosocial trauma transmission from one generation to the next via the placental oxytocinergic pathway. Encompassing three …

The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig

Dissertations, Theses, and Capstone Projects

Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …

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 …

How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster

Theses and Dissertations

A mounting body of evidence suggests that Eye Movement Desensitization and Reprocessing therapy (EMDR) is successful in reducing the impact of posttraumatic symptoms. Although the exact mechanisms of action remain unknown, theories from the psychological to the neuroscientific continue to emerge, expand, and evolve. This study will examine four of the most prominent theories to date and weigh the evidence for and against each one. It will also review, compare, and contrast the theories, evaluate the research supporting each one, and propose the most likely explanation for EMDR's success given the state of the research. Neurobiological mechanisms and correlates as …

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …

Validating Empathy As Captured By The Meanness In Psychopathy-Self Report, Stephanie Marie Molina

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychopathy is a distinctive personality disorder with an array of interpersonal and affective deficits. In particular, deficits in affective and cognitive empathy skills are noted to be a central feature of psychopathy. Specifically, the construct of psychopathic meanness, which is conceptualized as a tendency to act aggressively without regard for others, is preferentially related to deficient empathy. To elucidate the relationship between psychopathic meanness and empathy, three studies were conducted utilizing the Meanness in Psychopathy-Self Report (MiP- SR). The MiP-SR is a new measure that parses apart the construct of psychopathic meanness into three factors: Malice, Coldness, and Imperviousness. MiP-SR …

Efficaciousness Of Mindfulness Interventions For Trauma Using Psychophysiological Measures: A Review, Sherief Y. Eldeeb

Scholarly Undergraduate Research Journal at Clark (SURJ)

In recent decades the efficaciousness of mindfulness has been proven in a wide variety of contexts, but some crucial populations remain understudied. This review critically examines the literature on mindfulness in individuals with trauma using psychophysiological measures. Psychophysiological measures offer critical insight into this intersection of mindfulness and trauma due to the known somatic components in each, as well as serving as an objective response. Mindfulness-based treatments seem to show great promise in treating trauma, however there are significant limitations in the literature. Future studies should standardize the minimum length of treatment, utilize gender-balanced and ethnically diverse samples, and introduce …

Obesity Related Perturbations On Cardiovascular, Immune And Endocrine Response To Active And Passive Stress, Ashley Elizabeth Burch

Electronic Theses and Dissertations

As the obesity epidemic increases, the prevalence of obesity-related diseases grows simultaneously. The internal environment of chronic low-grade inflammation, which characterizes obesity, leaves individuals vulnerable to disease. Cardiovascular dysfunction represents a consequential effect of obesity. An early indicator of cardiovascular disease is an impaired stress response. Further, the type of stress (active versus passive) may be differentially affected representing additional distinctions in impairment. In the present study, we have used two types of stress (active and passive) to investigate obesity-instigated alterations in cardiovascular, immune and endocrine response to stress. In addition, we have evaluated how these systems may overlap to …

The Psychophysiology Of Self-Defining Memories, Rachel K. Hess

Psychology Honors Papers

Throughout the past 15 years, researchers have explored self-defining memories within the larger category of autobiographical memories (Conway, Singer, & Tagini, 2004; Singer, 2005; Singer & Salovey, 2003; Wood & Conway, 2006). Other researchers have examined the physiological reactions to various stimuli, some related to autobiographical memory (Gross & Levenson, 1997; Levenson & Gottman, 1983; Philippot, Schaefer, & Herbette, 2003; Schaefer & Philippot, 2005; Schwartz, Weinberger, & Singer, 1981). The present study is the first experiment to investigate the relationship of physiological correlates to self-defining memories. This study had participants generate their own self-defining and autobiographical memories, and recall them, …
