The phobic fear response appears to resemble an intense form of normal threat responding that can be induced in a nonthreatening situation. However, normative and phobic fear are rarely contrasted directly, thus the degree to which these two types of fear elicit similar neural and bodily responses is not well understood. To examine biological correlates of normal and phobic fear, 21 snake phobic and 21 nonphobic controls saw videos of slithering snakes, attacking snakes and fish in an event-related fMRI design. Simultaneous eletrodermal, pupillary, and self-reported affective responses were collected. Nonphobic fear activated a network of threat-responsive brain regions and involved pupillary dilation, electrodermal response and self-reported affect selective to the attacking snakes. Phobic fear recruited a large array of brain regions including those active in normal fear plus additional structures and also engendered increased pupil dilation, electrodermal and self-reported responses that were greater to any snake versus fish. Importantly, phobics showed greater between- and within-subject concordance among neural, electrodermal, pupillary, and subjective report measures. These results suggest phobic responses recruit overlapping but more strongly activated and more extensive networks of brain activity as compared to normative fear, and are characterized by greater concordance among neural activation, peripheral physiology and self-report. It is yet unclear whether concordance is unique to psychopathology, or rather simply an indicator of the intense fear seen in the phobic response, but these results underscore the importance of synchrony between brain, body, and cognition during the phobic reaction.

Thirty years of brain imaging research has converged to define the brain's default network-a novel and only recently appreciated brain system that participates in internal modes of cognition. Here we synthesize past observations to provide strong evidence that the default network is a specific, anatomically defined brain system preferentially active when individuals are not focused on the external environment. Analysis of connectional anatomy in the monkey supports the presence of an interconnected brain system. Providing insight into function, the default network is active when individuals are engaged in internally focused tasks including autobiographical memory retrieval, envisioning the future, and conceiving the perspectives of others. Probing the functional anatomy of the network in detail reveals that it is best understood as multiple interacting subsystems. The medial temporal lobe subsystem provides information from prior experiences in the form of memories and associations that are the building blocks of mental simulation. The medial prefrontal subsystem facilitates the flexible use of this information during the construction of self-relevant mental simulations. These two subsystems converge on important nodes of integration including the posterior cingulate cortex. The implications of these functional and anatomical observations are discussed in relation to possible adaptive roles of the default network for using past experiences to plan for the future, navigate social interactions, and maximize the utility of moments when we are not otherwise engaged by the external world. We conclude by discussing the relevance of the default network for understanding mental disorders including autism, schizophrenia, and Alzheimer's disease.
BACKGROUND: The frontal lobe has been crucially involved in the neurobiology of major depression, but inconsistencies among studies exist, in part due to a failure of considering modulatory variables such as symptom severity, comorbidity with anxiety, and distinct subtypes, as codeterminants for patterns of brain activation in depression.
METHODS: Resting electroencephalogram was recorded in 38 unmedicated subjects with major depressive disorder and 18 normal comparison subjects, and analyzed with a tomographic source localization method that computes the cortical three-dimensional distribution of current density for standard electroencephalogram frequency bands. Symptom severity and anxiety were measured via self-report and melancholic features via clinical interview.
RESULTS: Depressed subjects showed more excitatory (beta3, 21.5-30.0 Hz) activity in the right superior and inferior frontal lobe (Brodmann's area 9/10/11) than comparison subjects. In melancholic subjects, this effect was particularly pronounced for severe depression, and right frontal activity correlated positively with anxiety. Depressed subjects showed posterior cingulate and precuneus hypoactivity.
CONCLUSIONS: While confirming prior results implicating right frontal and posterior cingulate regions, this study highlights the importance of depression severity, anxiety, and melancholic features in patterns of brain activity accompanying depression.

Given the limited success of conventional treatments for veterans with posttraumatic stress disorder (PTSD), investigations of alternative approaches are warranted. We examined the effects of a breathing-based meditation intervention, Sudarshan Kriya yoga, on PTSD outcome variables in U.S. male veterans of the Iraq or Afghanistan war. We randomly assigned 21 veterans to an active (n = 11) or waitlist control (n = 10) group. Laboratory measures of eye-blink startle and respiration rate were obtained before and after the intervention, as were self-report symptom measures; the latter were also obtained 1 month and 1 year later. The active group showed reductions in PTSD scores, d = 1.16, 95% CI [0.20, 2.04], anxiety symptoms, and respiration rate, but the control group did not. Reductions in startle correlated with reductions in hyperarousal symptoms immediately postintervention (r = .93, p < .001) and at 1-year follow-up (r = .77, p = .025). This longitudinal intervention study suggests there may be clinical utility for Sudarshan Kriya yoga for PTSD.

Neurophysiological studies may explain how breathing techniques normalize stress response, emotion regulation, and autonomic and neuroendocrine system function. Breath practices have been shown to reduce symptoms of stress, anxiety, insomnia, post-traumatic stress disorder, mass disasters, depression, and attention deficit disorder. Technology-assisted breathing interventions facilitate therapeutic breathing by using either static cues such as a breath pacer or real-time feedback based on physiological parameters such as heart rate variability. The empirical literature indicates that technology-assisted breathing can be beneficial in mental health treatment, though it may not be appropriate for all individuals. Initial in-person training and evaluation can improve results.

Individuals who suffer from trauma-related symptoms are a unique population that could benefit from the mind-body practice of yoga-or have their symptoms reactivated by it, depending on the type of yoga. Trauma-informed yoga (TIY), that is, yoga adapted to the unique needs of individuals working to overcome trauma, may ameliorate symptoms by creating a safe, tailored practice for students to learn how to respond, rather than react, to symptoms and circumstances. Yoga not thus adapted, on the other hand, may increase reactivity and activate symptoms such as hyperarousal or dissociation. This article reports on expert input about adapting yoga for individuals with trauma, with special considerations for military populations. Eleven experts, recruited based on literature review and referrals, were interviewed in person or via telephone and asked seven questions about trauma-informed yoga. Verbatim transcripts were subjected to open-coding thematic analysis and a priori themes. Findings revealed that TIY needs to emphasize beneficial practices (e.g., diaphragmatic breath and restorative postures), consider contraindications (e.g., avoiding sequences that overly engage the sympathetic nervous system), adapt to limitations and challenges for teaching in unconventional settings (e.g., prisons, VA hospitals), and provide specialized training and preparation (e.g., specialized TIY certifications, self-care of instructors/therapists, adaptions for student needs). TIY for veterans must additionally consider gender- and culture-related barriers, differing relationships to pain and injury, and medication as a barrier to practice.

OBJECTIVE:To test whether a brief mindfulness meditation training intervention buffers self-reported psychological and neuroendocrine responses to the Trier Social Stress Test (TSST) in young adult volunteers. A second objective evaluates whether pre-existing levels of dispositional mindfulness moderate the effects of brief mindfulness meditation training on stress reactivity.
METHODS:
Sixty-six (N=66) participants were randomly assigned to either a brief 3-day (25-min per day) mindfulness meditation training or an analytic cognitive training control program. All participants completed a standardized laboratory social-evaluative stress challenge task (the TSST) following the third mindfulness meditation or cognitive training session. Measures of psychological (stress perceptions) and biological (salivary cortisol, blood pressure) stress reactivity were collected during the social evaluative stress-challenge session.
RESULTS:
Brief mindfulness meditation training reduced self-reported psychological stress reactivity but increased salivary cortisol reactivity to the TSST, relative to the cognitive training comparison program. Participants who were low in pre-existing levels of dispositional mindfulness and then received mindfulness meditation training had the greatest cortisol reactivity to the TSST. No significant main or interactive effects were observed for systolic or diastolic blood pressure reactivity to the TSST.
CONCLUSIONS:
The present study provides an initial indication that brief mindfulness meditation training buffers self-reported psychological stress reactivity, but also increases cortisol reactivity to social evaluative stress. This pattern may indicate that initially brief mindfulness meditation training fosters greater active coping efforts, resulting in reduced psychological stress appraisals and greater cortisol reactivity during social evaluative stressors.

The authors investigate the claim that thin slices of expressive behavior serve as reliable indicators of affective style in children and their families. Using photographs, the authors assessed smile intensity and tactile contact in kindergartners and their families. Consistent with claims that smiling and touch communicate positive emotion, measures of children’s smile intensity and warm family touch were correlated across classroom and family contexts. Consistent with studies of parent–child personality associations, parents ’ warm smiles and negative facial displays resembled those of their children. Finally, consistent with observed relations between adult personality and positive display, children’s smiling behavior in the classroom correlated with parent ratings of children’s Extraversion/Surgency. These results highlight the utility of thin slices of smiling and touch as indicators of child and family affective style.

This much-needed book will help schools and, by extension, society to better understand and identify the promise, potential, and possibilities of Black boys. Drawing from their wealth of experience in early childhood education, the authors present an asset- and strengths-based view of educating Black boys. This positive approach enables practitioners and school leaders to recognize, understand, and cultivate the diversity of social skills of Black boys in the early grades (pre-K-3rd grade). Each chapter begins with a vignette to illustrate what is lost when Black boys are prevented from participating freely in boyhood, having to instead attend to adult and peer interactions and attitudes that view them as "bad boys" and "troublemakers." This accessible book provides teachers with classroom strategies to help young Black boys achieve their highest potential, along with other resources for supporting their social-emotional development, such as a reading list of authentic multicultural children's books with Black boys as protagonists. Book features: (1) Challenges deficit views of Black boys in order to transform the way schools and society think, talk, and write about them; (2) Provides culturally responsive strategies for engaging Black boys and fostering healthy self-identity and agency; (3) Discusses the importance of critical self-reflection to examine attitudes and practices that inform how teachers engage with children and families; and (4) Examines how school officials, beginning in early childhood, can stop the adultification and criminalization of Black boys.

Most studies of meditation have focused on "actual affect" (how people actually feel). We predict that meditation may even more significantly alter "ideal affect" (how people ideally want to feel). As predicted, meditators ideally wanted to feel calm more and excited less than nonmeditators, but the groups did not differ in their actual experience of calm or excited states (Study 1). We ruled out self-selection and nonspecific effects by randomly assigning participants to meditation classes, an improvisational theater class, or a no class control (Study 2). After eight weeks, meditators valued calm more but did not differ in their actual experience of calm compared with the other groups. There were no differences in ideal or actual excitement, suggesting that meditation selectively increases the value placed on calm. These findings were not due to expectancy effects (Study 3). We discuss the implications of these findings for understanding how meditation alters affective life.
OBJECTIVES: Because the use of complementary and alternative medicine (CAM) is increasing among veterans, understanding more about the characteristics of veterans who use CAM is increasingly important. Studies reporting on predictors of use almost always discuss CAM in the aggregate, yet each CAM modality represents a unique approach to healthcare, and each may have different correlates as well as different effectiveness. Very little information is available about veterans' use of each distinct modality, and about psychosocial correlates of various forms of CAM use. DESIGN: We analyzed data from wave 1 of the Survey of the Experiences of Returning Veterans (SERV) Study, which included 729 veterans returning from Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF) and Operation New Dawn (OND). SETTING: Data were collected by telephone interviews. MAIN MEASURES: We examined a range of potentially important correlates of CAM use, including demographics, military experiences, and current mental and physical health. RESULTS: Each predictor related to a unique constellation of CAM modalities; not one of the predictors examined was associated with more than half of the 12 modalities. For example, women were more likely to use acupuncture, massage, yoga, meditation and spiritual healing, and age related only to greater use of homeopathy, while deployment injuries related positively to use of chiropractic, nutrition and meditation. CONCLUSIONS: Results suggest that in order to understand CAM use, CAM modalities should be considered unique and separate practices. This greater understanding should be useful for future health service provision for veterans.

PURPOSE: Yoga is a "mind-body" exercise, a combination of physical poses with breathing and meditation, and may have beneficial effects on physical and psychosocial symptoms. We aimed to explore cancer patients' motives for practicing yoga, experiences of practicing yoga, and perceived physical and psychosocial outcomes.METHODS: Participants (n = 45) following yoga classes for cancer patients were asked to participate in focus group interviews, of whom 29 participated. The focus groups (n = 5) were audio taped with prior consent and transcribed verbatim. Data were analyzed by two coders and independently coded into key issues and themes.
RESULTS: Mean age of the participants was 53.8 (SD 10.8) years, of whom 25 were women, and 18 were diagnosed with breast cancer. Motives for participation in yoga were relaxation, the will to be physically active, the wish to pay more attention to one's body, coping with psychosocial symptoms, contributing to their cancer rehabilitation process, and combing physical and mental processes. Main physical and psychosocial experiences of yoga mentioned by patients were regaining body awareness, raising attention to the inner self, learning how to relax, enjoyment, and finding recognition and understanding. Increased physical fitness and function, mental strength and resilience, increased coping, being more relaxed, and happiness were frequently mentioned experiences of patients.
CONCLUSIONS: Patients with different types of cancer perceived several benefits on physical and psychosocial outcomes by practicing yoga. Therefore, yoga can be a valuable form of supportive care for cancer patients.
Cancer is the uncontrolled growth of cells, which damages healthy tissue and causes disease. The American Cancer Society differentiates more than 100 types of cancers that manifest in diverse ways throughout the human body. Treatment of cancer can vary from local to systemic and from mildly invasive to radical depending on the type of cancer and the extent of disease.
