Mindfulness Meditation: Effects Of A Brief Intervention On Cardiovascular Reactivity During Acute Stress, Dustin Lamar Jones Jul 2013

Mindfulness Meditation: Effects Of A Brief Intervention On Cardiovascular Reactivity During Acute Stress, Dustin Lamar Jones

Theses and Dissertations

Mindfulness has historically been cultivated via formal meditation practice and the majority of meditation research examines individuals with extensive training or participants in Mindfulness based stress reduction programs that require considerable expense, a trained facilitator, and take approximately 8 weeks to complete. However, current literature does not speak directly to those who do not have the time or ability for such commitments. Formal mindfulness meditation practice and interventions reduce stress in various populations; however, the outcomes of a one-time intervention are relatively unknown. This study aims to examine whether a one-time (20-min) mindfulness meditation intervention would improve cardiovascular variables during …

The Effects Of Acute Psychosocial Stress On Cognitive Performance, Anne I.S. Gray Jul 2013

The Effects Of Acute Psychosocial Stress On Cognitive Performance, Anne I.S. Gray

Doctoral Dissertations and Master's Theses

The purpose of this study was to examine the effects of acute psychosocial stress on cognitive performance. Psychosocial stress evolves from the perceived presence of a social evaluative threat and results in the activation of the home hypothalamic-pituitary-adrenal axis. As part of this reaction the stress hormone cortisol is secreted into the blood stream, ultimately crossing the blood-brain barrier, where it can have profound effects on various aspects of cognition. A review of the literature reveals that that attention, working memory, spatial judgment and cognitive processing efficiency are particularly susceptible to stress induced changes in performance level. A test battery …

Relationship Between Emotional Intelligence And People’S Abilities To Cope With Stress, Lucile Michel May 2013

Relationship Between Emotional Intelligence And People’S Abilities To Cope With Stress, Lucile Michel

Undergraduate Psychology Research Methods Journal

Nowadays, it is really important for the researchers to understand the origins of stress, because it has been established that stress is really harmful for the human beings and is the cause to many diseases. Emotional intelligence has been shown to influence various areas of life, while several research studies state that EI has an effect on people’s abilities to cope with stress. Many studies affirm that EI, because of its effect on perceived stress, would have an influence on people’s aptitudes to manage a team, communicating with colleagues, and leadership skills. Because, today, in many workplaces, for interviews, managers …

What Are The Relations Among Stress Perception, Health Perception And Activity Participation In School-Aged Children?, Allison Caplin Apr 2013

What Are The Relations Among Stress Perception, Health Perception And Activity Participation In School-Aged Children?, Allison Caplin

Honors Theses and Capstones

This correlational study examined possible relations among children’s activity patterns, perceived stress, and perceived health. A variety of self-report questionnaires were administered to a sample of 33 school age children. The Pediatric Activity Sort (PACS) was used to measure activity participation, a health questionnaire was used to assess health, and the Childhood Stress Questionnaire (CSQ) was used to measure perceived stress. Correlations showed no significant relationships between stress level and the amount of reported activity participation. The absence of significant relationships may be due to testing a sample of middle to upper class, Caucasian children, as there was a skewed …

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis Mar 2013

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (Taeniopygia Guttata), Kimberly Anne Laplante Jan 2013

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (Taeniopygia Guttata), Kimberly Anne Laplante

Wayne State University Dissertations

Stress and affiliative social relationships are bi-directionally related. It is well understood that social relationships can buffer the physiological response to a stressor. Conversely, there is some evidence to suggest that stress can affect the propensity to form a pair bond. Data from humans and prairie voles, monogamous rodents, suggest that activation of the hypothalamic-pituitary-adrenal axis (HPA) in males increases attraction for females. Across species, females are understudied, but evidence from the prairie vole suggests HPA activation impairs formation of partner preference, the first step in establishing a pair bond. Across taxa there is evidence that formation and maintenance of …

Predictors Of Burnout And Vigor Among Clinical And Counseling Psychology Doctoral Students, Brett Swords Jan 2013

Predictors Of Burnout And Vigor Among Clinical And Counseling Psychology Doctoral Students, Brett Swords

Legacy Theses & Dissertations (2009 - 2024)

Work-related burnout, although connected to many negative outcomes (Kahill, 1988), has not been thoroughly studied in the graduate student population. The goal of the present study was to examine burnout and vigor among clinical and counseling psychology doctoral students. Based on conservation of resources theory (Hobfoll & Freedy, 1993; Hobfoll & Shirom, 2001), five variables were selected as predictors of burnout and vigor: two types of general work-related stress (i.e., pressure and threat; Stanton et al., 2001), the supervisory working alliance, financial strain, and conflict with others in the workplace. Seven hypotheses were tested about the expected relation between burnout …

Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam

Legacy Theses & Dissertations (2009 - 2024)

Attempts to define mindfulness in the clinical and psychological sciences have been marred by contradictions, inconsistencies, and controversies. In this wait-list (WL) controlled mindfulness meditation training (MMT) study, the efficacy and potential mechanisms of MMT was tested in a community sample with undiagnosed, but significant, symptoms of anxiety, depression, and stress. In a pre/post design, which also included 3 month follow-up, participants completed self-report measures, participated in a psychosocial stress task (before and after which they completed self-report mood questionnaires and had physiological and salivary neuroendocrine markers collected), and completed an emotional attentional blink paradigm. Compared to WL (n = …

Schizotypy: The Dynamic Relationship Between Trait And State Processes, Rebecca K. Macaulay Jan 2013

Schizotypy: The Dynamic Relationship Between Trait And State Processes, Rebecca K. Macaulay

LSU Master's Theses

Importantly, elevations in emotional reactivity to stress are often found in individuals vulnerable for psychosis. This study investigated several meaningful factors that appear to either increase vulnerability to stress (degree of schizotypy traits, trait negative affect, low perceived control, and impaired selective attention), or increase resiliency to stress (trait positive affect). A modified Posner spatial-cueing task utilizing affective cues was employed to assess selective attention within a neutral and an uncontrollable stressor condition. Between group differences (high, medium and low in schizotypy traits) and interactions between affective traits, state affect, and perceived control were evaluated in order to shed light …

Impact Of Binaural Beat Technology On Vigilance Task Performance, Psychological Stress And Mental Workload, Elizabeth Ann Shoda Jan 2013

Impact Of Binaural Beat Technology On Vigilance Task Performance, Psychological Stress And Mental Workload, Elizabeth Ann Shoda

Browse all Theses and Dissertations

Currently, there is only one published study examining the impact of binaural beats on the performance of a laboratory vigilance task, however this study had mixed results and left many questions unanswered. I further examined this phenomenon by using a successive vigilance task, between-subjects design, and a control condition to determine whether beta frequency binaural beats could affect vigilance performance over time and across conditions. I hypothesized that participants listening to beta binaural beats would have more hits and fewer misses on the vigilance task than participants in the control condition. In addition, I hypothesized that participants listening to beta …

Brain Mechanisms Underlying The Impact Of Attachment-Related Stress On Social Cognition, Tobias Nolte, Danielle Z. Bolling, Caitlin M. Hudac, Peter Fonagy, Linda Mayes, Kevin A. Pelphrey

Department of Psychology: Faculty Publications

Mentalizing, in particular the successful attribution of complex mental states to others, is crucial for navigating social interactions. This ability is highly influenced by external factors within one’s daily life, such as stress. We investigated the impact of stress on the brain basis of mentalization in adults. Using a novel modification of the Reading the Mind in the Eyes Test (RMET-R) we compared the differential effects of two personalized stress induction procedures: a general stress induction (GSI) and an attachment-related stress induction (ASI). Participants performed the RMET-R at baseline and after each of the two inductions. Baseline results replicated and …

The Interactive Effects Of Coping Strategies, Gender, And Stress In The Prediction Of Internalizing Symptoms In African American Youth: An Application Of The Specificity Model, Cynthia Pierre Jan 2013

The Interactive Effects Of Coping Strategies, Gender, And Stress In The Prediction Of Internalizing Symptoms In African American Youth: An Application Of The Specificity Model, Cynthia Pierre

Master's Theses

The current study utilized a specificity framework in the examination of interactions among coping strategies, stressor domains, and participant gender in the prediction of depressive and anxiety symptoms. Participants were 273 African American adolescents (6th - 8th; mean age = 12.9; 58% female). Participants completed measures of universal and culturally-relevant coping strategies in response to a stressor. Stressors were coded by raters across dichotomous domains: interpersonality (interpersonal vs. non-interpersonal), duration (acute vs. chronic), controllability (controllable vs. non-controllable), and sexuality (sexual vs. non-sexual). T-tests were conducted to examine differences in reported coping across stress domains. Inconsistent with predictions, mean differences of …

Ocbs And Strain: The Moderating Role Of Control, Kevin Loo Jan 2013

Ocbs And Strain: The Moderating Role Of Control, Kevin Loo

USF Tampa Graduate Theses and Dissertations

Organizational citizenship behaviors (OCBs) are typically assumed to be beneficial to employees and organizations. However, research has recently questioned this assumption. This study seeks to identify when OCBs are related to various strains and are detrimental to the employee or the organization. Specifically, using a stressor-strain model, it is hypothesized that in general, OCBs will be related to work effort; however, when employees feel pressured to perform OCBs, and thereby feel less control, OCBs will be more related to various strains. The hypotheses were partially supported: under all conditions, OCBs were related to effort, but under conditions of feeling forced, …

The Influences Of Caregiver-Child Interactions And Temperament On Cortisol Concentrations Of Toddlers In Full-Day Childcare, Helen Morris Lane Dec 2012

The Influences Of Caregiver-Child Interactions And Temperament On Cortisol Concentrations Of Toddlers In Full-Day Childcare, Helen Morris Lane

Electronic Theses and Dissertations

The purpose of this study was to explore the influences of caregiver-child interaction and temperament on cortisol concentrations of toddlers in full-day childcare. Sensitive and responsive caregiving is critical to the quality of children's early experiences. Caregivers who are attuned to unique needs of young children can support and guide child growth and development. In the context of relationships the child grows, develops, and learns to biologically respond to events in his or her world that he or she may perceive as threatening, with the production of cortisol. Studies show that regulation of cortisol release later in life may be …

Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres Dec 2012

Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres

LSU New Orleans Theses and Dissertations

Stress has been widely shown to directly influence people’s emotional and behavioral processing as well as their underlying biological systems. This project examined physiological and behavioral responses as indicators of stress and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. Physiological measures include autonomic biomarkers (e.g., heart-rate, skin conductance) at rest and during the stressor while behavioral indicators that were coded include acute verbal and non-verbal actions exhibited by participants during the …

Negative Event Appraisals, Cognitive Processing, And Adjustment, Kristen E. Riley Nov 2012

Negative Event Appraisals, Cognitive Processing, And Adjustment, Kristen E. Riley

Master's Theses

Appraisals of stressful events are linked to their adjustment to those stressful events. Appraisals can include perceptions of an event as threatening, uncontrollable, controllable, central, or challenging (Peacock & Wong, 1990). Many studies have examined effects of these appraisals on adjustment and cognitive processing (Aldwin, 2007; Lazarus, 1993; Tan, Jensen, Thornby, & Anderson, 2005), and a few have suggested that cognitive processing mediates relationships between appraisals and adjustment (Peacock & Wong, 1996). We tested cognitive processing in mediation models between appraisals and adjustment, and compared to active coping, in the context of ongoing stressors. Active coping appears to be particularly …

Racism And Illicit Drug Use Among African American Women: The Protective Effects Of Ethnic Identity, Affirmation, And Behavior, Danelle Stevens-Watkins, Brea Perry, Kathi L. Harp, Carrie B. Oser

Sociology Faculty Publications

Though recent evidence indicates that rates of illicit drug use among African American women are now higher than the national average, little is known about the etiology of substance use in this population. In addition, the effects of racism and other cultural factors are understudied and may be unique amongst African American women. This cross-sectional study explores risk and protective factors for drug use among 204 African American women. More specifically, associations between racism experiences and drug use are investigated in the context of potential moderating influences (i.e., psychosocial resources, social safety net variables, and cultural identity and practices). Findings …

Oprm1 Gene Variation Influences Hypothalamic-Pituitary-Adrenal Axis Function In Response To A Variety Of Stressors In Rhesus Macaques, Melanie L. Schwandt, Stephen G. Lindell, James Dee Higley, Stephen J. Suomi, Markus Heilig, Christina S. Barr Oct 2012

Oprm1 Gene Variation Influences Hypothalamic-Pituitary-Adrenal Axis Function In Response To A Variety Of Stressors In Rhesus Macaques, Melanie L. Schwandt, Stephen G. Lindell, James Dee Higley, Stephen J. Suomi, Markus Heilig, Christina S. Barr

Faculty Publications

The endogenous opioid system is involved in modulating a number of behavioral and physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. In humans, a functional variant in the OPRM1 gene (OPRM1 A118G) is associated with a number of outcomes, including attenuated HPA axis responses to stress. A nonsynonymous variant (OPRM1 C77G) in the rhesus macaque has been shown to have similar effects in vivo to the human variant. The current study investigated whether OPRM1 C77G influences HPA axis response to stress in rhesus macaques. We analyzed plasma adrenocorticotropic hormone (ACTH) and cortisol levels measured in response to three different stressors: 1) …
