Vocal Expression Of Emotions In Mammals: Mechanisms Of Production And Evidence, Elodie Briefer

Elodie Briefer, PhD

Emotions play a crucial role in an animal’s life because they facilitate responses to external or internal events of significance for the organism. In social species, one of the main functions of emotional expression is to regulate social interactions. There has recently been a surge of interest in animal emotions in several disciplines, ranging from neuroscience to evolutionary zoology. Because measurements of subjective emotional experiences are not possible in animals, researchers use neurophysiological, behavioural and cognitive indicators. However, good indicators, particularly of positive emotions, are still lacking. Vocalizations are linked to the inner state of the caller. The emotional state …

Altered Emotional Interference Processing In The Amygdala And Insula In Women With Post-Traumatic Stress Disorder, Steven E. Bruce, Katherine R. Buchholz, Wilson J. Brown, Laura Yan

Steven Bruce

Background: Post-Traumatic Stress Disorder (PTSD) is characterized by distinct behavioral and physiological changes. Given the significant impairments related to PTSD, examination of the biological underpinnings is crucial to the development of theoretical models and improved treatments of PTSD. Methods: We used an attentional interference task using emotional distracters to test for top-down versus bottom-up dysfunction in the interaction of cognitive-control circuitry and emotion-processing circuitry. A total of 32 women with PTSD (based on an interpersonal trauma) and 21 matched controls were tested. Event-related functional magnetic resonance imaging was carried out as participants directly attended to, or attempted to ignore, fear-related …

The Relationship Between Early Life Stress And Microstructural Integrity Of The Corpus Callosum In A Non-Clinical Population, Robert H. Paul, Lorrie Henry, Stuart M. Grieve, Thomas J. Guilmette

Robert Paul

Background: 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. 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. …

Pilates, Mindfulness And Somatic Education, Karen Caldwell, Marianne Adams, Rebecca Quinn, Mandy Harrison, Jeffrey M. Greeson

Jeffrey M. Greeson

The Pilates Method is a form of somatic education with the potential to cultivate mindfulness – a mental quality associated with overall well-being. However, controlled studies are needed to determine whether changes in mindfulness are specific to the Pilates Method or also result from other forms of exercise. This quasi-experimental study compared Pilates Method mat classes and recreational exercise classes on measures of mindfulness and well-being at the beginning, middle and end of a 15 week semester. Total mindfulness scores increased overall for the Pilates Method group but not for the exercise control group, and these increases were directly related …

Stress-Induced Changes In The Expression Of Monocytic Β2-Integrins: The Impact Of Arousal Of Negative Affect And Adrenergic Responses To The Anger Recall Interview, Jeffrey M. Greeson, James G. Lewis, Karen Achanzar, Eugene Zimmerman, Kenneth H. Young, Edward C. Suarez

Jeffrey M. Greeson

Adhesion of circulating monocytes to the vascular endothelium is one of the earliest steps in the development of atherosclerosis. This leukocyte-to-endothelium interaction is mediated in part by β2-integrins, a group of cell adhesion molecules that bind to endothelial ligands. Given the significance of this interaction to atherogenesis, we examined the effects of stress, operationalized as the arousal of negative affect (NA) and cardiovascular and catecholamine responses to the Anger Recall Interview (ARI), on the expression of LFA-1 (CD11a), Mac-1 (CD11b) and p150/95 (CD11c) on circulating monocytes (CD14+). Subjects were 173 healthy, nonsmoking men and women (60% men, 40% minorities, aged …

Hair Cortisol As A Biomarker Of Stress In Mindfulness Training For Smokers., Simon B Goldberg, Alison R Manley, Stevens S Smith, Jeffrey M Greeson, Evan Russell, Stan Van Uum, Gideon Koren, James M Davis

Jeffrey M. Greeson

OBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group. PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation. OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after …

Changes In Spirituality Partly Explain Health-Related Quality Of Life Outcomes After Mindfulness-Based Stress Reduction., Jeffrey M Greeson, Daniel M Webber, Moria J Smoski, Jeffrey G Brantley, Andrew G Ekblad, Edward C Suarez, Ruth Quillian Wolever

Jeffrey M. Greeson

Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (N = 279; M (SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis …

Developing Mindfulness In College Students Through Movement Based Courses: Effects On Self-Regulatory Self-Efficacy, Mood, Stress, And Sleep Quality, Karen Caldwell, Mandy Harrison, Marianne Adams, Rebecca H. Quin, Jeffrey M. Greeson

Jeffrey M. Greeson

Objective—This study examined whether mindfulness increased through participation in movement based courses and whether changes in self-regulatory self-efficacy, mood, and perceived stress mediated the relationship between increased mindfulness and better sleep. Participants—166 college students enrolled in the 2007-2008 academic year in 15 week classes in Pilates, Taiji quan, or GYROKINESIS®. Methods—At beginning, middle, and end of the semester, participants completed measures of mindfulness, self-regulatory self-efficacy, mood, perceived stress and sleep quality. Results—Total mindfulness scores and mindfulness subscales increased overall. Greater changes in mindfulness were directly related to better sleep quality at the end of the semester after adjusting for sleep …

A Randomized Controlled Trial Of Koru: A Mindfulness Program For College Students And Other Emerging Adults., Jeffrey M Greeson, Michael K Juberg, Margaret Maytan, Kiera James, Holly Rogers

Jeffrey M. Greeson

OBJECTIVE: To evaluate the effectiveness of Koru, a mindfulness training program for college students and other emerging adults. PARTICIPANTS: Ninety students (66% female, 62% white, 71% graduate students) participated between Fall 2012 and Spring 2013. METHODS: Randomized controlled trial. It was hypothesized that Koru, compared with a wait-list control group, would reduce perceived stress and sleep problems, and increase mindfulness, self-compassion, and gratitude. RESULTS: As hypothesized, results showed significant Group (Koru, Wait-List)×Time (Pre, Post) interactions for improvements in perceived stress (F[1, 76.40]=4.50, p=.037, d=.45), sleep problems (F [1, 79.49]=4.71, p=.033, d=.52), mindfulness (F [1, 79.09]=26.80, p CONCLUSIONS: Results support the …

Shop 'Til You Drop: A Coping Mechanism For Stressed University Students?, Aileen M. Pidgeon, Leanne Bottomley, Amy Bannatyne

Amy Bannatyne

Compulsive buying is a concerning problem affecting university students who are particularly vulnerable to experiencing anxiety and stress due to academic workloads, financial difficulties, and social isolation. The current study explores the relationship between compulsive buying behaviour, gender differences, anxiety, stress, and coping styles among university students. As expected, findings revealed female university students reported significantly higher levels of compulsive buying behaviour compared to male students, and students engaging in compulsive buying behaviours were significantly younger than non-compulsive buying students. Compared to university students who reported regular purchasing behaviours, university students who engaged in compulsive buying also reported significantly higher …

Qualitative Behavioural Assessment And Quantitative Physiological Measurement Of Cattle Naïve And Habituated To Road Transport, C. A. Stockman, T. Collins, A. L. Barnes, D. Miller, S. L. Wickham, D. T. Beatty, D. Blache, F. Wemelsfelder, P. A. Fleming

Françoise Wemelsfelder, PhD

The present study examined whether observers could distinguish between cattle that are naïve to road transport and the same cattle after becoming more habituated to transport. The behavioural expression of cattle was assessed through the method of qualitative behavioural assessment (QBA), and these assessments were correlated with various physiological parameters. Fourteen Angus steers were assessed during their first road trip and then again on their ninth trip, 15 days later. Blood samples were collected immediately before and after transport, and heart rate and core body temperature were measured continuously throughout each trip. Video footage recorded during each trip was edited …

Relationships Among Transformational And Transactional Leadership Styles, Role Pressures, Stress Levels, And Coping Resources In Senior Queensland Catholic Education Executives, Lynette Hand, Richard Hicks, Mark Bahr

Mark Bahr

There is considerable research available on general organizational leadership but limited research in relation to religious educational organizations and the leadership styles of executive staff. The Queensland Catholic Education (QCE) executives are thought to emphasize transformational more than transactional leadership styles but little information is available on the relationships of these styles to stress within the faith-based organizations, and to the role stressors faced and levels of coping resources. This paper reports on a study of 136 QCE executive leaders (of the total 220 executives) relating leadership styles adopted, strain (stress) experienced, personal coping resources, and selected role stressors (role …

Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant

Colleen S. Conley

This research investigated whether exposure to peer stress serves as one pathway through which pubertal development contributes to depression over time, differentially for girls and boys. Youth (N = 149; 9.6–14.8 years) and their caregivers provided information at two waves, 1 year apart, on puberty (Wave 1), peer stress (occurring between Waves 1 and 2), and depression (Waves 1 and 2). Structural equation modeling analyses examined sex differences in the extent to which peer stress mediated the impact of pubertal status and timing on subsequent depression (i.e., tests of moderated mediation). Significant sex-moderated mediation was found for both pubertal status …

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …

Coping And Ego Depletion: Recovery After The Coping Process, Roy Baumeister, Jon Faber, Harry Wallace

Harry M. Wallace

In this chapter, we combine a new approach to the self with a traditional, standard idea about coping in order to understand the coping process. The central idea is that many operations of the self involve the consumption of a limited resource. This resource is used in volition (e.g., choice, responsible decision-making, and active responses) and self-control. Stress makes severe demands on this resource, because people must engage in active responding and must regulate themselves so as to adapt to difficult circumstances. One major consequence of stress is that the resource becomes depleted. This will impair the person's functioning across …

Which Aspects Of Sensory Features Are Associated With Elevated Cortisol Concentrations In Boys With An Autism Spectrum Disorder?, Vicki Bitsika, Christopher Sharpley, Nicholas Andronicos, Linda Agnew, Richard Mills

Vicki Bitsika

Difficulties in Sensory Features (SF) have been included in the most recent diagnostic processes for Autism Spectrum Disorder (ASD) and are more common in children with an ASD than their non-ASD peers. In addition, these difficulties with SF have been suggested as causing elevated stress and concentrations of salivary cortisol in young people with an ASD. However, previous studies have not examined the specific aspects of SF that are associated with elevated cortisol and that was the focus of this study with 135 boys with an ASD aged 6–18 years. The boys’ mothers assessed their sons’ SF with the Sensory …

Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers

Mark Edwards

Attentional control theory (ACT) predicts that trait anxiety and situational stress interact to impair performance on tasks that involve attentional shifting. The theory suggests that anxious individuals recruit additional effort to prevent shortfalls in performance effectiveness (accuracy), with deficits becoming evident in processing efficiency (the relationship between accuracy and time taken to perform the task). These assumptions, however, have not been systematically tested. The relationship between cognitive trait anxiety, situational stress, and mental effort in a shifting task (Wisconsin Card Sorting Task) was investigated in 90 participants. Cognitive trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through …

Workplace Stress, Personality, Personal Resources And Mindfulness Practices Of 21 Australian Based Counsellors, Richard Hicks, Clive Jones, Victoria Alexander

Richard Hicks

There have been several older studies of counsellors at work in Australia but none recently that have examined the relationships of full-time practising counsellors in the light of their experienced stress, their personality patterns and their resources including mindfulness attributes. The current study set out to gather extensive information on how counsellors experienced their work roles and relationships and how they coped with the circumstances they faced. A series of questionnaires was used in the study including the Occupational Stress Inventory- Revised (which yielded responses on stressors at work related to the role of the counsellor, experienced stress or strain …

Goats, Crayons And Bananas – Creative Ways To Fight Student Stress, Conny Liegl

Conny Liegl

More than 80% of US college students report feeling overwhelmed and exhausted, almost half of whom describe their academic experience as traumatic or very difficult to handle. Stress, sleep difficulties and anxiety are just some of the symptoms that manifest in college students. Undergraduates seem particularly susceptible to these stressors, but only one in five seeks medical consultation for their issues. (American College Health Association [ACHA], 2013)

To help students react to external and internal stressors, California Polytechnic State University’s Robert E. Kennedy Library initiated a program to support students during the most stressful times of the academic quarter. With …

Effects Of Stretch-Based Progressive Relaxation Training On The Secretion Of Salivary Immunoglobulin A In Orofacial Pain Patients, Jeffrey Sherman, Charles Carlson, James Mccubbin, John Wilson

James A. McCubbin

There is a growing body of evidence that psychologic stressors can affect physical health and proneness to disease through depletion of the body's immune system. Relatively little research, however, has investigated the potential immunoenhancing effect of stress-relieving strategies such as progressive muscle relaxation. This study explored the relationship between immune functioning and relaxation training with persons experiencing persistent facial pain. In a single experimental session, 21 subjects either received relaxation training or rested for an equivalent time period. Salivary immunoglobulin A, mood, pain, and tension levels were measured before and after relaxation and rest periods. Results indicated that a greater …

Self-Esteem Influences On Multiple Domains: Stress, Health, Mood, And Social Identity, Kymberlee O'Brien, Hannah Lapp, Stephanie Powers, Celia Moore

Kymberlee M. O'Brien

The present investigation assessed self-esteem effects on biological and subjective chronic stress measures, including cardiovascular parameters, health indicators, and mood. Moderators were examined, including vagal tone and social identity. High self-esteem was associated with higher baseline positivity, lower baseline negativity, and lower subjective stress across numerous domains including: city stress, chaos at home, and perceived stress (all p<.05). Vagal tone moderated the relationship between self-esteem and the chronic stress measure: hair cortisol (p<.05). The high self-esteem group showed lower cortisol, particularly when coupled with high vagal tone. Individuals with low vagal tone had the highest cortisol; for those …

The Role Of Social Support In Adolescents: Are You Helping Me Or Stressing Me Out?, Gonzalo Bacigalupe, Maria Camara

Gonzalo Bacigalupe, EdD, MPH

Interpersonal relationships are indispensable in helping adolescents cope with stressors, acting as social support sources that protect them from psychological distress. Learning from their experiences may elucidate what strategies could be employed to support adolescents during this vulnerable life stage. Focus groups (N = 80) with adolescents in the Basque Country, Spain, were conducted to capture adolescents' narratives on stress and social support. Findings revealed the dual role of interpersonal relationships – as stressors and as sources of social support. Adolescents draw on sources of support that are familiar, mature, friendly, and, most importantly, worth of trust. Their most valued …

Mediating Factors Of Perceived Discrimination: Physiological And Affective Markers., Kymberlee O'Brien, Edward Tronick, Celia Moore

Kymberlee M. O'Brien

Early life adversity influences later health and may be mediated by psychosocial, affective, and physiological stress and immune factors. We report evidence from MIDUS biomarker project (N = 845, age 34-84, M = 55.09, SD = 11.70) confirming the predicted relationship between early adversity and frequency of diagnosed chronic illnesses (M = 2.8, SD =1.2). Specific psychosocial and physiological variables were tested as mediators. Lifetime (M = .95, SD = 1.5) and daily (M = 12.8, SD = 1.2) discrimination, urinary cortisol (M = 1.1, SD = 1.2 ug/dL), IL-6 (M =2.8, SD = 2.8 pg/mL) (all ps<.001), and …

Depression, Anxiety, And Stress Among Mothers Of Healthy Children And Mothers Of Children With Cochlear Implants, Seyed Mohammad, Kalantarkousheh, دکتر سید محمد کلانتر کوشه

Seyed Mohammad Kalantarkousheh

Background: The birth of a disabled child is one of the resonant factors that can cause family disorders. Mothers who have disabled children experience different levels of anxiety and stress. Decreased hearing, meanwhile, is one of the major reasons for disability. Parents have different concerns about their children’s development and social relations. Cochlear implantation is a new way to cure deafness and enables the disabled child to hear, talk, and communicate. This research intends to compare the outbreak of depression, anxiety, and stress among mothers who have healthy children and those of cochlear implantation children. Additionally, the research examines if …

How Prostate Cancer Patients Cope: Evaluation And Refinement Of The Prostate Cancer Patients' Coping Strategies Questionnaire, Christopher Sharpley, Vicki Bitsika, David Christie

Vicki Bitsika

Background: Prostate cancer (PCa) patients suffer from identifiable stressors that may cause them anxiety and/or depression. In a previous study, an initial exploration of the ways in which PCa patients seek to cope with those stressors was described. However, several methodological limitations prevented direct comparisons of the relative effectiveness of patients’ coping strategies. To further investigate this issue, a standardised format was used to present the most commonly-used coping strategies to a new sample of PCa patients and to compare the effectiveness of those strategies. Methods: A total of 147 PCa patients completed a background questionnaire and the Prostate Cancer …
