The Effects Of Acute Stress On Human Prefrontal Working Memory Systems, Anthony J. Porcelli, Daniel Cruz, Karen Wenberg, Michael D. Patterson, Bharat B. Biswal, Bart Rypma

Psychology Faculty Research and Publications

We examined the relationship between acute stress and prefrontal-cortex (PFC) based working memory (WM) systems using behavioral (Experiment 1) and functional magnetic resonance imaging (fMRI; Experiment 2) paradigms. Subjects performed a delayed-response item-recognition task, with alternating blocks of high and low WM demand trials. During scanning, participants performed this task under three stress conditions: cold stress (induced by cold-water hand-immersion), a room temperature water control (induced by tepid-water hand-immersion), and no-water control (no hand-immersion). Performance was affected by WM demand, but not stress. Cold stress elicited greater salivary cortisol readings in behavioral subjects, and greater PFC signal change in fMRI …

Background The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a large cohort of WTC rescue, recovery, and cleanup workers. We previously documented extensive pulmonary dysfunction in this cohort related to toxic environmental exposures. Objectives Our objective in this study was to describe mental health outcomes, social function impairment, and psychiatric comorbidity in the WTC worker cohort, as well as …

Crowding In Context: An Examination Of The Differential Responses Of Men And Women To High-Density Living Environments, Wendy C. Regoeczi

Sociology & Criminology Faculty Publications

This study examines the question of gender-equivalent outcomes of mental health and social behavior in the context of crowding stress. It tests the hypothesis that gender will influence the exhibition of stress outcomes resulting from exposure to high-density living environments, with women displaying internalized responses and men responding with externalized styles. Expanding on the types of gender-appropriate disorders examined in this area of research, I selected depression, aggression, and withdrawal as gender-specific disorders based on theory and prior research. Multilevel analyses of data from a survey of Toronto residents indicate that, while the effects of household density are conditioned by …

Biology And Therapy Of Fibromyalgia. Evidence-Based Biomarkers For Fibromyalgia Syndrome, Dina Dadabhoy, Leslie J. Crofford, Michael Spaeth, I. Jon Russell, Daniel J. Clauw

Internal Medicine Faculty Publications

Researchers studying fibromyalgia strive to identify objective, measurable biomarkers that may identify susceptible individuals, may facilitate diagnosis, or that parallel activity of the disease. Candidate objective measures range from sophisticated functional neuroimaging to office-ready measures of the pressure pain threshold. A systematic literature review was completed to assess highly investigated, objective measures used in fibromyalgia studies. To date, only experimental pain testing has been shown to coincide with improvements in clinical status in a longitudinal study. Concerted efforts to systematically evaluate additional objective measures in research trials will be vital for ongoing progress in outcome research and translation into clinical …

A Stressor-Strain Model Of Organizational Citizenship Behavior And Counterproductive Work Behavior, Kimberly E. O'Brien

USF Tampa Graduate Theses and Dissertations

Prior research has attempted to develop a model of organizational citizenship behaviors (OCB) and counterproductive work behaviors (CWB), but limited testing remains a problem. The purpose of the current study is to examine OCB and CWB from a job stressor-strain approach. The sample consisted of 235 employees throughout the United States and their supervisors. Results of the study suggested OCB and CWB are affected by stressors (including interpersonal conflict, low interactional justice, job demands, and organizational constraints). Additionally, trait emotion and attributional styles affect the amount of stressors perceived. The implications as well as limitations of the study are discussed.

Sticking It To The Man By Standing By Your Man: Social Support As An Act Of Resistance , Andrew Middleton Wallace

LSU New Orleans Theses and Dissertations

The purpose of this paper is to synthesize literatures on stress, social support, symbolic interaction, and de Certeau as they pertain to the recovery of a homosexually-identified individual from a homophobic interaction. A model of the initial stressful interaction as well as the interaction between a homosexually-identified individual and his socially-supportive network is posited with the consumption of culturally-disseminated roles and the salience of role-identities as the mechanisms by which it works. The model is then considered as a form of resistance in the light of broader gay liberation social movements. The study focuses on white, middle-class, American, homosexually-identified males …

Increasing Paramedic Student's Resiliency To Stress: Assessing Correlates And The Impact Of Intervention, Shirley Porter

Faculty and Staff Publications - CRI

The daily occupational stressors that paramedics must deal with, place these individuals at higher risk for physiological distress and burnout than the general population. Recently, attention has been focused on trying to identify the correlates of occupational stress. A review of the literature indicated that peer support, attitude towards emotional expression, and ways of coping may be predictive of psychological distress and burnout symptoms among this group of professionals. The current pilot study focused on paramedic students in the final year of their college program. Using a pre-test, post-test design, including a treatment and control group, this study sought to …

Romance In College: Effects Of Relationship Stress And Commitment On Scholastic Performance, Lauren Alderson, Kate Gruenloh

Undergraduate Psychology Research Methods Journal

Due to the increased number of observed college students involved in romantic relationships, we decided to conduct a study to see if any correlation existed between those involved in romantic relationships and the students’ academics. In addition to this hypothesis, we were also interested in the varying levels of stress and commitment of a romantic relationship and their influence on academic performance. However after surveying 66 college participants regarding their feelings and opinions about their current or past relationships, our statistical findings did not support our initial research hypothesis.

Yoga As An Intervention For Stress Reduction And Enhanced Wellbeing In African American Athletes, Jennifer Fallon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study explored the preventive impact of a brief Hat ha yoga program on stress-reduction and enhanced wellbeing in a sample of healthy African American college athletes. African Americans suffer higher rates of hypertension and sudden cardiac death syndrome, both linked to stress. Study design was single case, with six replications, utilizing comparison of pre- and post-intervention scores on physiological and psychological indicators of distress and wellbeing. Findings were inconsistent across participants and measures, though generally included beneficial increases in positive affect (i.e ., C = 0.567 , Z = 2 071, p < 0.05) and perceived physical health (i.e., C = 0489, Z = 1. 721, …

Escape From Death Row: A Study Of “Tripping” As An Individual Adjustment Strategy Among Death Row Prisoners, Sandra Mcgunigall-Smith, Robert Johnson

The University of New Hampshire Law Review

[Excerpt] “The literature on stress and coping in American prisons tends to focus on the social dimensions of prison life. This literature describes a prison culture that shapes prison adjustment; such a culture entails norms, roles, and groups (including gangs) that dictate norms of adjustment. The literature also suggests that prisoners have to find a way to get along in the more public areas of the prison (such as the prison yard or mess hall) or retreat to smaller worlds within the prison while carving out “niches” that allow them to adjust in ways they find more familiar—in their jobs, …

Jurisdictions And Causes Of Action: Commercial Considerations In Dealing With Bullying, Stress And Harassment Cases-Part Ii, Niall Neligan

Articles

In the concluding part of this two part article, the author will
examine how the courts have developed rules for dealing with
tortious claims for psychiatric injuries arising out of bullying, stress
and harassment cases. The article will examine whether it is
desirable to consolidate and codify employment rights law in order
to provide clarity to prospective litigants. Finally, the author will
argue that if codification is required, then this will necessitate a
change in the nature of present jurisdictions for bringing claims
involving bullying, stress and harassment in the workplace.

Effects Of Sex, Age, And Season On Plasma Steroids In Free-Ranging Texas Horned Lizards (Phrynosoma Cornutum), Corina L. Wack, Stanley F. Fox, Eric C. Hellgren, Matthew P. Lovern

Publications

The Texas horned lizard (Phrynosoma cornutum) is protected in several states due to its apparently declining numbers; information on its physiology is therefore of interest from both comparative endocrine and applied perspectives. We collected blood samples from free-ranging P. cornutum in Oklahoma from April to September 2005, spanning their complete active period. We determined plasma concentrations of the steroids, progesterone (P), testosterone (T), and corticosterone (CORT) by radioimmunoassay following chromatographic separation and 17β-estradiol (E2) by direct radioimmunoassay. T concentrations in breeding males were significantly higher than in non-breeding males. P showed no significant seasonal variation within either sex. …

However, studies have not examined the relationship between ELS and the microstructural integrity of the brain. Previous studies have examined the impact of early life stress (ELS) on the gross morphometry of brain regions, including the corpus callosum. However, studies have not examined the relationship between ELS and the microstructural integrity of the brain. Methods: In the present study we evaluated this relationship in healthy non-clinical participants using diffusion tensor imaging (DTI) and self-reported history of ELS. …

Religiosity And Successful Aging, Jessica L. York

ETD Archive

There has been an increasing amount of elderly individuals who have avoided the crippling health and physical problems that appear to vex so much of the older adult population. These successful agers have also learned to cope more effectively with both the normative and traumatic stressors they encounter over time. Successful aging has been defined in numerous ways and studied in a variety of contexts. This study set to define successful aging in terms of anxiety, depression, and subjective well-being, while also examining the relationship of successful aging with religiosity. The fundamental goal of this study was to examine the …

Developing Higher Consciousness: The Effects Of Mantra Meditation On The Development Of Self-Actualizing Qualities In Teachers, Lisa M. Klein

Electronic Theses and Dissertations

This qualitative study focuses on teachers ranging from the elementary to secondary level who have practiced mantra meditation for at least three years while also teaching. By utilizing the methodology of portraiture, this study endeavored to determine if the practice of mantra meditation creates self-actualizing qualities in teachers, how teachers who practice mantra meditation perceive their response to stress and conflict in the classroom, and how teachers who practice mantra meditation perceive the effects of meditation on their personal and professional lives. The methodology of portraiture was chosen because according to Lawrence-Lightfoot, "with its focus on narrative, with its use …

Retributive Justice, Restorative Justice, And Forgiveness: An Experimental Psychophysiology Analysis, Charlotte Vanoyen-Witvliet, Everett L. Worthington, Lindsey M. Root, Amy F. Sato, Thomas E. Ludwig, Julie J. Exline

Faculty Publications

This experiment assessed the emotional self-reports and physiology of justice outcomes and forgiveness responses to a common crime, using a three Justice (retributive, restorative, no justice) × 2 Forgiveness (forgiveness, none) repeated-measures design. Participants (27 males, 29 females) imagined their residence was burglarized, followed by six counterbalanced justice–forgiveness outcomes. Imagery of justice—especially restorative—and forgiveness each reduced unforgiving motivations and negative emotion (anger, fear), and increased prosocial and positive emotion (empathy, gratitude). Imagery of granting forgiveness (versus not) was associated with less heart rate reactivity and better recovery; less negative emotion expression at the brow (corrugator EMG); and less aroused …

The Steroid Sulfatase Inhibitor (P-O-Sulfamoyl) - Tetradecanoyl Tyramine (Du-14) Enhances Memory Retention In Passive Avoidance In Rats With Hippocampal Cholinergic Deficit, Phebian Arinola Abitoye

Electronic Theses and Dissertations

Neurosteroids, such as dehydroepiandrosterone sulfate, (DHEAS) are steroidal compounds synthesized within the central nervous system that modulate its function. Among the effects associated with sulfated neurosteroids is the enhancement of memory. Previous studies have demonstrated that altering the metabolism of neurosteroids via inhibition of the enzyme steroid sulfatase could reverse scopolamine-induced amnesia. p-O-(Sulfamoyl) - tetradecanoyl tyramine (DU-14) is a steroid sulfatase inhibitor (SSI) that prevents the conversion of DHEAS to DHEA thereby increasing the concentration of sulfated neurosteroids to potentiate the effect of endogenous DHEAS. To determine whether DU-14 could enhance memory retention for footshock in rats with hippocampal cholinergic …

Teacher Self-Efficacy, Collective Teacher Efficacy, Automatic Thoughts, States Of Mind, And Stress In Elementary School Teachers, Robert W. Shambaugh

This study examined the relationships between teacher self-efficacy, collective teacher efficacy, automatic thoughts, Balanced States of Mind (BSOM) model, and levels of stress in regular education elementary school teachers. A sample of 66 teachers from rural and urban south central Pennsylvania school districts completed the following questionnaires: Teacher Beliefs Scale (TBS), Collective Teacher Beliefs Scale (CTBS), Automatic Thoughts Questionnaire - Revised (ATQR), Teacher Stress Inventory (TSI), and a demographic survey. A ratio of positive to positive-plus-negative automatic thoughts from the Balanced States of Mind model (BSOM) became the fifth variable. This study presumes that teachers have more stress today following …

Adolescents' Stress And Health: Parental Influences And Cognitive Mediators, Reesa Donnelly

Electronic Theses and Dissertations

Research to date indicates that parental and cognitive variables play a role in stress responses and health outcomes. Although researchers are beginning to focus on developmental processes in stress/health outcomes, there is little research examining which parental behaviors are most predictive of stress/health and whether cognitive variables mediate this relationship. As a result, the current study examines the self-reports of 160 late adolescents regarding parental behaviors, cognitive variables, and stress/health outcomes. In addition, blood pressure reactivity to a stressful situation was collected as a physiological measure of stress. The results suggest that, among the parental behaviors that are examined, parental …

Police Stress, Dennis J. Stevens

Political Science & Global Affairs Faculty Publications

This entry defines police officer stress and describes its consequences, origins, and the individual and organizational methods to control it. Controlling stress can enhance the delivery of police services and guide officers toward healthy lifestyles. One definition of stress is the wear and tear our bodies and minds experience as we react to physiological, psychological, and environmental changes throughout our lives. It is a nonspecific response of the body to a demand for change. Its centerpiece is the relationship between an external event and an internal response: For every action, there’s a reaction.

Rapports de recherche scientifique

Cliquez ici pour la version française de ce rapport

Malgré une quantité impressionnante de données empiriques démontrant les conséquences néfastes du stress au travail sur la santé des individus et des organisations, il existe peu d’évidences scientifiques sur le processus d’implantation et l’efficacité des interventions visant à prévenir le stress au travail. Plusieurs revues de la littérature scientifique sur les programmes de prévention du stress au travail montrent la dominance des programmes de prévention centrés sur l’individu (DeFrank & Cooper, 1987; Van Der Hek & Plomp, 1997). Les effets associés à ce type d’intervention sont généralement limités et de durée …

The Phonetic Context Of American English Flapping: Quantitative Evidence, Dirk Elzinga, David Eddington

Faculty Publications

The phonetic context in which word-medial flaps occur (in contrast to [th]) in American English is explored. The analysis focuses on stress placement, following phone, and syllabification. In Experiment 1, subjects provided their preference for [th] or [ɾ] in bisyllabic nonce words. Consistent with previous studies, flaps were preferred before stressless syllables and [th] before stressed syllables, but the following phone also exerted a small degree of influence. Experiments 2 and 3 tested whether [th] or [ɾ] are associated with a particular syllable position in bisyllabic words. They demonstrate that [th] is favored in onsets, while [ɾ] is not consistently …

Stress Reducing Effects Of Oxytocin In A Maternal Separation Paradigm, Keely Jane O'Connell

Browse all Theses and Dissertations

This study compared the effects of centrally and peripherally administered oxytocin (OT) on HPA axis activity and the presence of both stress-induced active and passive behaviors in female guinea pig pups (Cavia porcellus) after 180-min of isolation . In Experiment 1, one dose of oxytocin (10μg/.2ml) was injected subcutaneously into the periphery. Plasma cortisol levels were reduced after 180-min of isolation and two passive behaviors, eye-closure and crouch, were reduced as well with the administration of oxytocin. In Experiment 2, two different doses (10μg/.2ml and 20μg/.2ml) were injected into the periphery with no significant results. In Experiment 3 one dose …

Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem

Electronic Theses and Dissertations

In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …
