OBJECTIVE: The anterior cingulate cortex has been implicated in depression. Results are best interpreted by considering anatomic and cytoarchitectonic subdivisions. Evidence suggests depression is characterized by hypoactivity in the dorsal anterior cingulate, whereas hyperactivity in the rostral anterior cingulate is associated with good response to treatment. The authors tested the hypothesis that activity in the rostral anterior cingulate during the depressed state has prognostic value for the degree of eventual response to treatment. Whereas prior studies used hemodynamic imaging, this investigation used EEG.
METHOD: The authors recorded 28-channel EEG data for 18 unmedicated patients with major depression and 18 matched comparison subjects. Clinical outcome was assessed after nortriptyline treatment. Of the 18 depressed patients, 16 were considered responders 4-6 months after initial assessment. A median split was used to classify response, and the pretreatment EEG data of patients showing better (N=9) and worse (N=9) responses were analyzed with low-resolution electromagnetic tomography, a new method to compute three-dimensional cortical current density for given EEG frequency bands according to a Talairach brain atlas.
RESULTS: The patients with better responses showed hyperactivity (higher theta activity) in the rostral anterior cingulate (Brodmann's area 24/32). Follow-up analyses demonstrated the specificity of this finding, which was not confounded by age or pretreatment depression severity.
CONCLUSIONS: These results, based on electrophysiological imaging, not only support hemodynamic findings implicating activation of the anterior cingulate as a predictor of response in depression, but they also suggest that differential activity in the rostral anterior cingulate is associated with gradations of response.

Love it or hate it, the Anthropocene is emerging as an inescapable word for (and of) the current moment. Popularized by Eugene Stoermer and Paul Crutzen, Anthropocene names an age in which human industry has come to equal or even surpass the processes of geology, and in which humans in their attempt to conquer nature have inadvertently become a major force in its destruction (Crutzen & Stoermer 2000; Steffen et al. 2011). This is the tragedy of the Anthropocene. But this tragedy also holds an odd, even schizophrenic, promise; namely the promise of scientific renewal and insight. For in the Anthropocene, nature is no longer what conventional science imagined it to be. And if the notion of a pure nature-an-Sich has died in the Anthropocene and been replaced by natural worlds that are inextricable from the worlds of humans, then humans themselves can no longer be what classical anthropology and human sciences thought they were. Arguably, the Anthropocene challenges us all to radically what nature, humans as well as the political and historical relationship between them might be at the end of the world, peppering its message of environmental doom with the promise of scientific renewal (and global survival) through trans-disciplinary collaboration. This bipolar message of a new science and a new politics amidst ruins is exhilarating for some, and seems to come at an opportune moment. Certainly, the notion that human lives and politics are producers of/produced by natural worlds gels with a growing attention within anthropology and neighboring disciplines to the diverse multispecies worlds that humans and non-humans cohabit. And yet, the Anthropocene may still be, as Bruno Latour puts it in...
Sleep quality tends to be poor among emerging adults (ages 18–25). Poor sleep quality has short- and long-term health consequences, including decreases in cognitive function and mood and reductions in immune function. Trait mindfulness, or observing experiences without becoming emotionally aroused or passing judgment, has been linked to increased sleep quality in emerging adults, but little research attention has examined mechanisms that may explain this relationship. Because mindfulness has been associated with reductions in both anxiety and depression, and anxiety and depression are associated with more sleep disturbances, it is possible that mindfulness may operate on sleep quality through reductions in both anxiety and depressive symptoms. This study examined the links between mindfulness, depressive symptoms, anxiety, and sleep quality in 283 emerging adults. Results indicated that higher levels of mindfulness were related to better sleep quality through lower levels of anxiety and depressive symptoms. Post hoc analyses indicated that mindfulness was also associated with fewer sleep disturbances and less daytime sleep dysfunction through lower levels of anxiety and depressive symptoms. However, higher levels of mindfulness were associated with longer sleep duration, better sleep efficiency, and better subjective sleep quality only through fewer depressive symptoms and higher levels of mindfulness were associated with shorter sleep latency only through anxiety. Results suggest that mindfulness may be an effective tool for increasing sleep quality in emerging adults.
Anxiety is a diffuse, unpleasant, and often vague subjective feeling of apprehension accompanied by objective symptoms of autonomic nervous system (ANS) arousal. The experience of anxiety is associated with a sense of danger or a lack of control over events. The psychological component varies from individual to individual and is strongly influenced by personality and coping mechanisms.
In this cross-sectional study, we examined age-related differences in anxiety sensitivity (AS), experiential avoidance (EA), and mindfulness among younger adult students (N = 426; M age = 20.1 years) and community-dwelling older adults (N = 85; M age = 71.8 years). Participants anonymously completed the Anxiety Sensitivity Index-3, Acceptance and Action Questionnaire-II, Mindful Attention Awareness Scale, Kentucky Inventory of Mindfulness Skills, Beck Anxiety Inventory, Geriatric Anxiety Scale, and State-Trait Anxiety Inventory. Independent t tests indicated that younger adults reported significantly higher levels of AS and EA, whereas older adults reported significantly higher levels of trait mindfulness. Correlational analyses demonstrated that AS and EA were significantly associated with each other and with anxiety-related symptoms. However, trait mindfulness was significantly inversely related to AS, EA, and to trait and state anxiety. To date, these three factors have yet to be examined simultaneously within the context of age differences, and the present study illuminates these differences as well as their relationships. AS, EA, and low mindfulness appear to be significant correlates for anxiety-related symptoms in younger and older adults.
<p>The article looks at Hugh Richardson's role in some of the foundational work in Tibetan studies. Richardson is recognized here as the last of the series of foreigners who spent time in Tibet before the Chinese Communist take-over. Much of Richardson's work focused on the cooperation of indigenous TIbetan scholars, and non-Tibetan researchers. These relationships have helped in the formation of the current discipline of Tibetan studies. (Mark Premo-Hopkins 2004-04-08)</p>
Objective: This study aims to investigate the effect of an integrated intervention of art activities and Qigong exercise on the well-being of older adults in nursing homes in Indonesia. Method: We employed a randomized controlled trial with 4 specific groups, i.e. art, Qigong, integration of art and Qigong, and control group. A total of 267 participants aged 50 years or older were recruited from 9 nursing homes in Jakarta, Indonesia. The participants were randomly allocated to one of the four groups, attending two intervention sessions per week for eight weeks (16 sessions), lasting 90 minutes each. Measurements were administered at baseline (T0) and post-intervention (T1). The primary outcome was well-being (WHOQOL-Bref) and secondary outcomes were satisfaction with life (SWLS), depression (BDI-II), and health status (SF-36). Results: The art intervention had a significant positive effect on well-being, in particular in the domain of social relations. It also led to a decrease in depressive symptoms, as did the integration intervention. No significant effects were visible in the Qigong group nor in the integrated intervention compared to either art or Qigong alone. Conclusion: Interventions such as art programs and an integration of art and Qigong may give psychological benefits to older adults. Yet, results of the study need to be interpreted with caution and need to be replicated. A qualitative approach would be welcome to get an in-depth understanding of why art intervention is especially beneficial.

Research Findings: Head Start teachers completed brief rating scales measuring the social-emotional competence and approaches to learning of preschool children (total N = 164; 14% Hispanic American, 30% African American, 56% Caucasian; 56% girls). Head Start lead and assistant teacher ratings on both scales demonstrated strong internal consistency and moderate interrater reliability. When examined longitudinally, preschool teacher-rated approaches to learning made unique contributions to the prediction of kindergarten and 1st-grade academic outcomes, need for supplemental services, and grade retention, even after we accounted for preschool academic skills. In contrast, preschool teacher-rated social-emotional competence made unique contributions to the prediction of reduced behavior problems and peer difficulties in kindergarten and 1st grade. Practice or Policy: The findings demonstrate that preschool teachers are able to provide distinct and reliable ratings of child social-emotional competence and approaches to learning using brief rating scales, with validity for predicting elementary school adjustment.
OBJECTIVES: This study assessed yoga as an adjuvant strategy for symptoms of combat-related posttraumatic stress disorder (PTSD). METHODS: Subjects had significant, combat-related PTSD. Control data were collected during an eight-week waiting period. Trauma-sensitive yoga sessions of 90 minutes duration were provided every seven days for eight weeks. Assessments included the PTSD checklist (PCL); the Depression, Anxiety and Stress Scale (DASS); the Pittsburgh Sleep Quality Index (PSQI); the Adult/Adolescent Sensory Profile (AASP); the SF36 Quality of Life instrument; and a brief, structured pre-enrolment assessment of attitudes towards yoga. Biomarkers were also assessed. RESULTS: Thirty participants were recruited, with 28 completing the protocol ( Mage=63.5 years). For most variables, there was no significant change in results after the waiting period. Comparing measurements obtained immediately prior to the commencement of the intervention to those taken after completion of eight yoga sessions, significant changes included an increase in the serum dehydroepiandrosterone concentration, decreased total PCL score (and all PCL sub-scales), decreases in all DASS sub-scale scores and significant improvements in PSQI and SF36 scores. No adverse events were reported. CONCLUSIONS: A range of benefits were observed after yoga, consistent with the theoretical construct for the long history of yoga as a strategy to reduce stress and promote well-being.

This study aimed to investigate the role of different types and frequencies of physical exercise in biomarkers of oxidative stress among middle-aged and elderly community residents with essential hypertension in China. A community-based cross-sectional survey was undertaken in 7 subdistricts. Individuals, 45-79 years old, with essential hypertension (n = 402) and without cardiovascular disease (n = 1047) were included. Superoxide dismutase (SOD) activities and plasma levels of malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) were determined. Multilevel linear regression was used to estimate the associations between various types of physical exercise and oxidative stress biomarker levels. Participants engaged in high frequency walking/square dancing or taiji/yoga demonstrated decreased systolic blood pressure in both groups; however, diastolic blood pressure decreased only among individuals with hypertension participating in walking/square dancing. In individuals with hypertension, MDA levels decreased in those participating in walking/square dancing, SOD activity increased in those participating in walking/square dancing, and 4-HNE levels decreased in those involved in taiji/yoga. In individuals without cardiovascular disease, MDA levels decreased in those involved in walking/square dancing or taiji/yoga, SOD activity increased in those performing walking/square dancing, and 4-HNE levels decreased in those involved in taiji/yoga. Oxidative stress marker levels also improved in those involved in walking/square dancing or taiji/yoga groups as the exercise frequency increased. Thus, frequent participation in walking/square dancing or taiji/yoga effectively decreases hypertension-related oxidative stress biomarker levels.
<p>Aliment Pharmacol Ther 2011; 34: 363–373SummaryBackground Stress perception and GI-specific anxiety play key roles in irritable bowel syndrome (IBS). Mindfulness-based stress reduction (MBSR) is a widely available stress reduction course, which has not been evaluated for IBS.Aim To determine whether participation in MBSR is associated with improvement in bowel symptoms, GI-specific anxiety, and IBS-Quality of Life.Methods This is a prospective study of 93 participants in MBSR. We applied measures of Rome III IBS status, bowel symptoms (IBS-Severity Scoring System, IBS-SSS), IBS-Quality of Life (IBS-QOL), GI-specific anxiety (Visceral Sensitivity Index, VSI), mindfulness (Five Facet Mindfulness Questionnaire-FFMQ), and functional status (SF-8) at baseline and 2 and 6 months after enrolment.Results At 2 months, participation in MBSR was associated with small nonsignificant changes in IBS-SSS, IBS-QOL and VSI: d = −0.25, d = 0.08, d = −0.16, respectively. At 6 months, there was no significant change in IBS-SSS (d = −0.36); whereas for IBS-QOL and VSI there were significant improvements (IBS-QOL: d = 0.33, P = 0.044; VSI: d = −0.40, P = 0.014). For patients meeting Rome III IBS criteria (n = 43), changes in IBS-SSS, IBS-QOL and VSI were not statistically significant, but there was a significant correlation between the change in VSI and the change in FFMQ across the three time periods (r = 0.33).Conclusions Participation in MBSR is associated with improvement IBS-related quality of life and GI-specific anxiety. Randomised controlled trials are warranted to further assess the role of MBSR for IBS symptomatology.</p>

Work stress, burnout, and diminished empathy are prevalent issues for health‐care professionals. Mindfulness meditation (MM) is one commonly used strategy to manage stress. Measuring salivary cortisol allows for the assessment of serum cortisol level, a known stress level indicator. This study evaluated the association of subject‐reported stress symptoms and salivary cortisol in health‐care professionals, in an 8‐week MM program, with data collected prospectively at baseline and 8 weeks after program completion. Questionnaires [Profile of Mood States—Short Form (POMS‐SF), Maslach Burnout Inventory (MBI), and Interpersonal Reactivity Index (IRI)] measured mood, burnout and empathy.A paired t‐test between groups for pre/post‐salivary cortisol yielded no significant change. The POMS‐SF was most sensitive to change (mean increase 12.4; p = 0.020). Emotional exhaustion, measured in the MBI, was also affected by MM (mean decrease 4.54; p = 0.001). Changes in empathy may not have been captured due to either absence of effect of MM on empathy, subject number or scale sensitivity. Baseline and 8‐week correlations between salivary cortisol and survey results, and correlations between changes in these measures, were weak and not statistically significant. Nevertheless, psychometric results present a strong case for additional clinical trials of MM to reduce stress for health‐care professionals.
Yoga practice is reported to lead to improvements in quality of life, psychological functioning, and symptom indices in cancer survivors. Importantly, meditative states experienced within yoga practice are correlated to neurophysiological systems that moderate both focus of attention and affective valence. The current study used a mixed methods approach based in neurophenomenology to investigate associations between attention, affect, and cardiac activity during a single yoga session for female cancer survivors. Yoga practice was associated with a linear increase in associative attention and positive affective valence, while shifts in cardiac activity were related to the intensity of each yoga sequence. Changes in attention and affect were predicted by concurrently assessed cardiac activity. Awareness of breathing, physical movement, and increased relaxation were reported by participants as potential mechanisms for yoga's salutary effects. While yoga practice shares commonalities with exercise and relaxation training, yoga may serve primarily as a promising meditative attention-affect regulation training methodology.
This study compared the asymmetry of different features of brain electrical activity during the performance of a verbal task (word finding) and a spatial task (dot localization) that had been carefully matched on psychometric properties and accompanying motor activity. Nineteen right-handed subjects were tested. EEG was recorded from F3, F4, C3, C4, P3, and P4, referred to both CZ and computer-derived averaged-ears references, and Fourier transformed. Power in the delta, theta, alpha, and beta bands was computed. There were significant Task X Hemisphere effects in all bands for CZ-referenced data and for the alpha and beta bands for ears-referenced data. The effects were always either greater power suppression in the hemisphere putatively most engaged in task processing or greater power in the opposite hemisphere. Correlations between EEG and task performance indicated that CZ-referenced parietal alpha asymmetry accounted for the most variance in verbal task performance. Power within individual hemispheres or across hemispheres was unrelated to task performance. The findings indicate robust differences in asymmetrical brain physiology that are produced by well-matched verbal and spatial cognitive tasks.

Background Mindfulness training (MT) programs represent an approach to attention training with well-validated mental health benefits. However, research supporting MT efficacy is based predominantly on weekly-meeting, facilitator-led, group-intervention formats. It is unknown whether participants might benefit from neurofeedback-assisted, technology-supported MT (N-tsMT), in which meditation is delivered individually, without the need for a facilitator, travel to a training site, or the presence of a supportive group environment. Mirroring the validation of group MT interventions, the first step in addressing this question requires identifying whether N-tsMT promotes measurable benefits. Here, we report on an initial investigation of a commercial N-tsMT system. Methods In a randomized, active control trial, community-dwelling healthy adult participants carried out 6 weeks of daily practice, receiving either N-tsMT (n = 13), or a control condition of daily online math training (n = 13). Training effects were assessed on target measures of attention and well-being. Participants also completed daily post-training surveys assessing effects on mood, body awareness, calm, effort, and stress. ResultsAnalysis revealed training effects specific to N-tsMT, with attentional improvements in overall reaction time on a Stroop task, and well-being improvements via reduced somatic symptoms on the Brief Symptom Inventory. Attention and well-being improvements were correlated, and effects were greatest for the most neurotic participants. However, secondary, exploratory measures of attention and well-being did not show training-specific effects. N-tsMT was associated with greater body awareness and calm, and initially greater effort that later converged with effort in the control condition. Conclusions Preliminary findings indicate that N-tsMT promotes modest benefits for attention and subjective well-being in a healthy community sample relative to an active control condition. However, the findings would benefit from replication in a larger sample, and more intensive practice or more comprehensive MT instruction might be required to promote the broader benefits typically reported in group format, facilitated MT.

Self-focused attention is an important target of intervention within Wells's (2009) metacognitive therapy and the attention training technique (ATT) is one component of metacognitive therapy that purportedly alters focus of attention. However, we do not yet fully understand whether ATT causes changes in focus of attention, the effectiveness of ATT compared to other techniques in reducing self-focused attention, and how ATT leads to its therapeutic gains. A laboratory-based component study was completed to address these gaps in the literature. Nonclinical participants were randomly assigned to one session of ATT (n = 38) or a mindfulness-based task (n = 38). ATT and the mindfulness-based task differentially changed focus of attention, with ATT causing greater external focus of attention and the mindfulness-based task causing greater self-focused attention from pre-to-post manipulation. ATT and the mindfulness-based task both led to reductions in anxiety. Reductions in self-focused attention were related to less anxiety following ATT, whereas increases in self-focused attention were related to less anxiety following the mindfulness-based task. Conceptual and therapeutic implications are discussed.
