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, …

Comparison Between The Effects Of Acute Physical And Psychosocial Stress On Feedback-Based Learning, Xiao Yang, Brittany Nackley, Bruce H. Friedman

Psychology Faculty Publications

Stress modulates feedback-based learning, a process that has been implicated in declining mental function in aging and mental disorders. While acute physical and psychosocial stressors have been used interchangeably in studies on feedback-based learning, the two types of stressors involve distinct physiological and psychological processes. Whether the two types of stressors differentially influence feedback processing remains unclear. The present study compared the effects of physical and psychosocial stressors on feedback-based learning. Ninety-six subjects (Mage = 19.11 years; 50 female) completed either a cold pressor task (CPT) or mental arithmetic task (MAT), as the physical or psychosocial stressor, while electrocardiography and …

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

Antioch University Full-Text 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 …

Stress, Resilience, And Impulsivity, Kendra Clark, Adam Runyan, Carissa Philippi

Undergraduate Research Symposium

Stress is a phenomenon that everyone will experience. Stress that is unmanageable can become chronic, which is linked to various negative psychological effects (Le Fevre, Matheny, & Kolt, 2003). Although stress research often focuses on the negative long-term effects, there are times where individuals develop a trait known as resilience. Resilient individuals eventually learn how to buffer the negative effects of stress (Cicchetti, 2010), and researchers have begun investigating the positive effects of resilience on stress (Cicchetti, 2010; Kermott, Johnson, Sood, R., Jenkins, & Sood, A., 2019). Currently, few studies have been conducted to identify any additional traits that may …

Positive affect (PA) is associated with better health across a wide range of physical health outcomes. This review reflects on why the study of PA is an essential component of our understanding of physical health and expands on pathways that connect these two variables. To encourage forward movement in this burgeoning research area, measurement and design issues in the study of PA and health are discussed, as are the connections between PA and a range of different health outcomes. Plausible biological, social, and behavioral pathways that allow for positive feelings to get under the skin and influence physical wellness are …

Analysis Of Endocrine Response To Perceived Difference In Cross-Cultural Interactions, Carole Woolford-Hunt, Marlene Murray, Tevni Grajales Guerra, Kristina Beenken-Johnson

Faculty Publications

We live in a world where awareness of ethnic and cultural diversity is an ever increasing reality. Business and education turn to the social sciences to inform them about how to manage and optimize cross-cultural interactions. Although much research has been done on the impact of cross-cultural interactions on a wide range of variables, one less researched area is the endocrine response to cross-cultural interactions. In this study we set out to investigate the endocrine response to cross cultural interactions and the impact of these interactions on perceived differences. To do so we measured the pre and post levels of …

Arousal Reappraisal And Interoceptive Awareness: How Awareness Of Bodily Changes Facilitates Heightened Performance And Ability To Reappraise, Wyndham Chalmers

All College Thesis Program, 2016-2019

The physiological arousal induced by a stressful situation has historically been viewed as bad; however, recent research has challenged this perspective, arguing that stress-related arousal can be beneficial. Arousal reappraisal is a coping technique that encourages individuals to reinterpret their physiological stress response as a means to help improve performance. Conversely, suppression, a common, yet ineffective coping technique, involves the active effort to stop oneself from expressing an emotional behavior. The current research examined the relationship between coping techniques and interoceptive awareness (IA), the degree to which individuals are aware of their own physiological changes. Comparing arousal reappraisal to both …

The Contribution Of A Polygenic Risk Score To Individual Differences In Aggressive Behavior: The Moderating And Mediating Roles Of Stressful Events, Christa C. Christ

Department of Psychology: Dissertations, Theses, and Student Research

Although aggression can be beneficial in certain situations (e.g. playing sports, self-defense), excessive and inappropriate aggression can lead to adverse physical and psychological health outcomes in both perpetrators and victims. Genetic susceptibility to negative environments can increase the likelihood of aggressive behavior in the context of situational risk factors. Low efficiency of serotonin neurotransmission and exposure to stress appear to play a prominent role in the etiology of aggressive behavior. A set of three studies assessed the contribution of polygenic risk (TPH2 rs4570625, SLC6A4 5-HTTLPR+rs25531, HTR1B rs13212041, MAOA uVNTR) to aggressive behavior, including alcohol-related aggression, in university students at varying …

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.

Stress And Eyewitness Memory: Timing Of Stressor And Association With Cortisol Stress Responding, Timothy Ryan Robicheaux

Department of Psychology: Dissertations, Theses, and Student Research

Witnesses to and victims of criminal events can face significant stress during such encounters. Stress responding consists of a multitude of responses (e.g., anxiety, cardiovascular changes, cortisol responding). In the current study, I utilized a physiological stressor (i.e., the cold-pressor test) and a facial recognition paradigm to examine the relationship between cortisol change following stress exposure and memory accuracy. More specifically, I examined whether cortisol levels at specific memory stages (i.e., acquisition and retrieval) predicted stress responding differently.

Findings suggested that individual differences in cortisol stress responding to the cold-pressor test predicted facial recognition when peak cortisol was at a …

Effects Of Increased Levels Of Prenatal Mesotocin On Postnatal Individual Recognition And Stress Responsiveness In Northern Bobwhite Quail (Colinus Virginianus), Brittany Yusko

FIU Electronic Theses and Dissertations

Oxytocin (OT) plays a key role in the mediation of social and stress behaviors across many species; however, the mechanism is still unclear. The present study investigated the influence of prenatal levels of mesotocin (MT; avian homologue of OT) on postnatal social and stress behavior in Northern bobwhite quail. Experiment one determined endogenous levels of MT during prenatal development using an enzyme-linked immunoassay kit. Experiment two examined the influence of increased MT during prenatal development on chicks' individual recognition ability and stress response to a novel environment. Experiment one showed MT levels increased significantly throughout embryonic development. Experiment two showed …

The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas

Masters Theses 1911 - February 2014

Alcohol is one of the most common drugs of choice among adolescents. Normally, the method of consumption is drinking large quantities of alcohol in short periods of time, otherwise known as “binge drinking.” Corticotropin releasing factor (CRF) stress peptide producing cells in central nucleus of the amygdala (CeA) has been implicated in behavioral responses to stress and addiction. The goals of this thesis were to determine the effects of voluntary binge drinking in adolescence and vapor-induced alcohol dependence in adulthood on CRF cells in the CeA. These studies were done using an operant model of voluntary binge drinking in rodents …

Effect Of Social Status On Behavioral And Neural Response To Stress, Daniel W. Curry, Kathleen E. Morrison, Matthew A. Cooper

Senior Thesis Projects, 2009

Individuals respond differently to traumatic stress. Social status, which plays a key role in how animals experience and interact with their social environment, may influence how individuals respond to stressors. In this study, we used a conditioned defeat model to investigate whether social status alters susceptibility to the behavioral and neural consequences of traumatic stress. Conditioned defeat is a model in Syrian hamsters in which an acute social defeat encounter results in a long term increase in submissive behavior and a loss of normal territorial aggression. To establish social status, we weight matched and paired Syrian hamsters in daily aggressive …

Salivary Cortisol, Psychological Stress And Depressive Symptoms Among Patients Undergoing Colon Cancer Screenings, Allyson Reid

Honors Scholar Theses

As the second leading cause of cancer-related deaths in the United States, colon cancer has a high cure rate if detected early by a colonoscopy (U.S.

Cancer Statistics Working Group, 2007). However, more than 41 million at-risk Americans are not properly receiving colonoscopy screenings according to the recommendations of the Center for Disease Control. This study provides insight into the physiological and psychological benefits of the colonoscopy procedure over and above cancer detection and prevention. Thirty-six patients receiving colonoscopic screening at the University of Connecticut Health Center participated in this study. A questionnaire battery that assessed perceived stress, depressive symptoms, …

A Meeting Of East And West: Can Eastern-Influenced Therapies Be Effective In The Treatment Of Stress And Mood Disorders?, Paula Pelavin

Undergraduate Research Symposium (UGRS)

Given that the human brain is plastic and that structural alterations have been seen in monks who meditate on a regular basis, the question arises of whether these two facts are actually related. Furthermore, if this is in fact the case, would it be possible to apply these findings to the public? In this paper I will present the different conditions that induce neuroplasticity as well as give an overview of meditation and the ways that it is practiced nowadays. To this end I will argue that if monks are able to alter the structure of their brains and the …
