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 …

Psychophysiological Predictors Of Change In Emotion Dysregulation 6 Months After Traumatic Injury, Jacklynn M. Fitzgerald, Sydney Clare Timmer-Murillo, Claire Sheeran, Hailey Begg, Morgan Christoph, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Emotional dysregulation that occurs after trauma conveys risk for multiple disorders, including posttraumatic stress disorder, depression, and anxiety. Psychophysiological data (e.g., skin conductance level [SCL]) may be a useful biomarker for quantifying emotion dysregulation given that autonomic nervous system (ANS)-mediated arousal may underlie this feature. In this longitudinal study, we tested whether SCL collected following a single-incident traumatic injury could predict changes in emotion dysregulation over 6 months. Sixty-six adults were recruited from the emergency department; SCL was quantified during an active trauma narrative, in which participants re-told their traumatic event to a research staff member, as well as a …

Cognitive Load Effect on Moral Decision Making

Elise Crause, Merry Bailey, Liz Eisenga, Caroline Hopper

Choices are made each day to determine the outcome of our lives. To better understand the human process of decision making, philosophers and psychologists have examined moral dilemmas. Cognitive load is a type of stress that alters decision-making and the likelihood of choosing a self-motivated behavior over a behavior that benefits another person or group. For this study, moral dilemmas were given in sets of two before and after a cognitive-load-inducing task. The cognitive-load-inducing task required participants to verbally answer subtraction problems until the answer …

The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria

Dissertations, Theses, and Capstone Projects

Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …

Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton

Electronic Thesis and Dissertation Repository

For decades researchers have used 2D stimuli under the assumption that they accurately represent real objects. This assumption has been challenged by recent vision and neuroeconomics research which has found that 2D images can evoke different neural and behavioural responses than real objects. The current study continues this line of research in the field of affective cognitive neuroscience; a field where small effect sizes are common and rapid habituation to affective stimuli used in the lab often occurs. The present study uses realistic 2D and 3D emotional images to determine the impact of visual dimension on affective responding. Subjective ratings …

Physiological Correlates Of Affective Decision-Making In Anxiety And Depression, Louisa I. Thompson

Dissertations, Theses, and Capstone Projects

Improving our understanding of cognitive and physiological profiles in anxiety and depression has the potential to reveal novel ways to target and improve treatments for these prevalent mental health conditions. The present study examined the impact of self-reported anxiety and depression symptoms on three established decision-making measures, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), Balloon Analogue Risk Task (BART; Lejuez et al., 2002), and Game of Dice Task (GDT; Brand et al., 2005), in a diverse sample of 100 college students (age 18 to 35). Physiological measures of tonic heart rate variability and galvanic skin response …

Obesity In Society: The Importance Of Perception, Michael Darnell Oliver Ii

Masters Theses

In the current study, I examined the role of positive and negative media images of obese individuals on attitudes and physiological responding in relation to an actual discrimination incident. Various surveys were administered and Body Mass Index (BMI), salivary Alpha Amylase (sAA), and Galvanic Skin Response (GSR) or Skin Conductance (SC) were measured. Participants read a vignette in which an obese individual was discriminated against and further questions were administered to assess attributional blame. My primary hypothesis in this study was that there would be a decrease in stigma due to positive priming, specifically stigma directed at the obese population. …

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.

Fear Conditioning And Extinction In Youth With Obsessive-Compulsive Disorder, Joseph F. Mcguire, Scott P. Orr, Monica S. Wu, Adam B. Lewin, Brent J. Small, Vicky Phares, Tanya K. Murphy, Sabine Wilhelm, Daniel S. Pine, Daniel Geller, Eric A. Storch

Psychology Faculty Publications

BACKGROUND: Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy (CBT). Youth with OCD may have impairments in fear acquisition and extinction that carry treatment implications. We examined these processes using a differential conditioning procedure.

METHODS: Forty-one youth (19 OCD, 22 community comparisons) completed a battery of clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases. Skin conductance response (SCR) served as the primary dependent measure.

RESULTS: During habituation, no difference between groups was observed. During acquisition, differential fear conditioning was observed …

Fear Conditioning And Extinction In Childhood Obsessive-Compulsive Disorder, Joseph F. Mcguire

USF Tampa Graduate Theses and Dissertations

Fear conditioning and extinction are central in the cognitive behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive behavioral therapy (CBT). Youth with OCD may have impairments in conditioning and extinction that carries treatment implications. The present study examined these processes using a differential conditioning paradigm. Forty-one youth (19 OCD, 22 community controls) and their parents completed a battery of clinical interviews, rating scales, and a differential conditioning task. Skin conductance response (SCR) served as the primary dependent measure across all three phases of the conditioning procedure (habituation, acquisition, and extinction). During habituation, no meaningful differences were observed between …

Psychic Collapse And Traumatic Defense: How The Mind Mediates Trauma Living In The Body, Patricia Kim Yoon

Dissertations, Theses, and Capstone Projects

The aim of this exploratory study was to link psychoanalytic theories of trauma and its impact on the mind with psychobiological research of how trauma lives in the body. The study has expanded on prior research (Cramer, 2003) to evidence that defense mechanisms do in fact moderate the relationship between stress and physiological response, and that there are likely individual differences in physiological response to traumatic stress. This study goes further to identify the psychological concomitants of these individual differences within an adult population exposed to potentially traumatic events (PTEs), and their proclivity for using different defense mechanisms. Defense use …

An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli

Psychology Faculty Research and Publications

Recently research on the relationship between stress and cognition, emotion, and behavior has greatly increased. These advances have yielded insights into important questions ranging from the nature of stress' influence on addiction1 to the role of stress in neural changes associated with alterations in decision-making^2,3. As topics being examined by the field evolve, however, so too must the methodologies involved. In this article a practical and effective alternative to a classic stress induction technique, the cold pressor test (CPT), is presented: the cold pressor arm wrap (CPAW). CPT typically involves immersion of a participant's dominant hand in ice-cold …

Effects Of Acute Stress And Gender On Decision-Making, Stephanie Elaine Wemm

Legacy Theses & Dissertations (2009 - 2024)

The current study examined the effects of a social stressor on subsequent performance on the Iowa Gambling Task (IGT), and the role of sex on this relationship. Fifty-six participants (24 men and 32 women) were assigned randomly to a social stressor (Trier Social Stress Test) or a control condition while their subjective emotional reactions and their physiological arousal (skin conductance and heart rate) were measured. Findings showed that participants in the stress condition responded with higher skin-conductance levels and heart rate during the social stressor, in addition to reporting greater negative affect directly following the social stressor. They also made …

Is Experiential Avoidance A Factor In Maternal Overprotection?, Melissa Nieves

Electronic Theses and Dissertations

The current study examined experiential avoidance (EA) as an explanation for parental overprotectiveness, a behavior often found among parents of anxious children. EA parenting theory posits that parents engage in overprotective behaviors in order to reduce their own anxiety. In order to test the theory, mothers’ electrodermal activity (EDA) and blindly-coded overprotective behaviors were examined when a child with SAD was engaged in a reading performance task. In line with EA theory, it was hypothesized that EDA levels would increase before an overprotective behavior (OB) occurred and decrease afterwards as a result of decrease in anxiety. The sample consisted of …

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 …

Enhancing The Benefits Of Written Emotional Disclosure Through Response Training, Andrea Konig, Alison Eonta, Stephanie R. Dyal, Scott R. Vrana

Psychology Publications

Writing about a personal stressful event has been found to have psychological and physical health benefits, especially when physiological response increases during writing. Response training was developed to amplify appropriate physiological reactivity in imagery exposure. The present study examined whether response training enhances the benefits of written emotional disclosure. Participants were assigned to either a written emotional disclosure condition (n = 113) or a neutral writing condition (n = 133). Participants in each condition wrote for 20 minutes on three occasions and received response training (n = 79), stimulus training (n = 84) or no training (n = 83). Heart …

Comorbidity Of Psychopathy In Schizotypy: Skin Conductance To Affective Pictures, Kathleen A. Ragsdale

Electronic Theses and Dissertations

Prior research substantiates a relationship between psychopathy and schizophrenia-spectrum disorders, which has begun to elucidate why some individuals with schizophrenia are violent. Unfortunately, this relationship has been limited to self-report. To objectively corroborate this finding, undergraduate students were recruited from an online screening administration of the Schizotypal Personality Questionnaire. This resulted in 56 participants (52% male) with a mean age of 20.37 (SD = 4.74) and a wide range of schizotypy scores who participated in the experiment. Following completion of self-report measures, participants viewed 15 pictures (five neutral, five threatening, and five of others in distress) from the International Affective …

Disclosure And Health: Enhancing The Benefits Of Trauma Writing Through Response Training, Andrea Konig

Theses and Dissertations

Writing about a personal traumatic event has been found to have psychological and physical health benefits. Focusing on traumatic memories in writing may be a form of exposure. In imagery exposure and trauma writing, greater physiological reactivity was predictive of better outcomes. Given the importance of physiological output in emotional processing, response training was developed and found to be effective in increasing appropriate physiological reactivity in imagery exposure. If response training amplifies physiological reactivity and the benefits of writing, the hypothesis that writing is a form of exposure would be strengthened, and training may be a valuable tool to improve …

Memory For Emotional Images: Mechanisms Of Episodic Processing And Its Psychophysiological Correlates, Gregory E. Devore

Loma Linda University Electronic Theses, Dissertations & Projects

Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for pure lists of taboo and neutral words. A similar result was found with equivalent recognition memory performance between pure lists of negative, positive, and neutral images. The current research is designed to test the predictions of binding theory using negative and neutral visual stimuli in mixed lists. A rapid serial visual presentation paradigm and recognition memory item-discrimination tasks are used. Binding theory predicts differences in recognition memory performance between arousing and neutral images in mixed lists, but not …

Unwanted Sexual Experience: An Investigation Of Emotion And Physiology, Julie Alberty

Loma Linda University Electronic Theses, Dissertations & Projects

The statistics on the prevalence of sexual abuse are varied and alarmingly large. Rojas and Kinder (2007) showed that a little less than 30% of males stated that they had been sexually abused while a little over 30% of females reported being sexually abused. The purpose of this study is to obtain additional information regarding cognitive-affective processing in individuals who have had an unwanted sexual experience. The current study is a pilot study that questions whether a difference in physiological response, as measured by skin conductance and heart rate, will occur in people who have had an unwanted sexual experience …

Memory Enhancement By A Semantically Unrelated Emotional Arousal Source Induced After Learning, Kristy A. Nielson, Douglas Yee, Kirk I. Erickson

Psychology Faculty Research and Publications

It has been well established that moderate physiological or emotional arousal modulates memory. However, there is some controversy about whether the source of arousal must be semantically related to the information to be remembered. To test this idea, 35 healthy young adult participants learned a list of common nouns and afterward viewed a semantically unrelated, neutral or emotionally arousing videotape. The tape was shown after learning to prevent arousal effects on encoding or attention, instead influencing memory consolidation. Heart rate increase was significantly greater in the arousal group, and negative affect was significantly less reported in the non-arousal group after …
