In the present study, we investigated if attention to faces results in sensory gain modulation. Participants were cued to attend to faces or scenes in superimposed face-scene images while face discriminability was parametrically manipulated across images. The face-sensitive N170 event-related potential component was used as a measure of early face processing. Attention to faces modulated N170 amplitude, but only when faces were not highly discriminable. Additionally, directing attention to faces modulated later processing (~230–300 msec) for all discriminability levels. These results demonstrate that attention to faces can modulate perceptual processing of faces at multiple stages of processing, including early sensory levels. Critically, the early attentional benefit is present only when the “face signal” (i.e., the perceptual quality of the face) in the environment is suboptimal.
We investigated the impact of mindfulness training (MT) on working memory capacity (WMC) and affective experience. WMC is used in managing cognitive demands and regulating emotions. Yet, persistent and intensive demands, such as those experienced during high-stress intervals, may deplete WMC and lead to cognitive failures and emotional disturbances. We hypothesized that MT may mitigate these deleterious effects by bolstering WMC. We recruited 2 military cohorts during the high-stress predeployment interval and provided MT to 1 (MT, n = 31) but not the other group (military control group, MC, n = 17). The MT group attended an 8-week MT course and logged the amount of out-of-class time spent practicing formal MT exercises. The operation span task was used to index WMC at 2 testing sessions before and after the MT course. Although WMC remained stable over time in civilians (n = 12), it degraded in the MC group. In the MT group, WMC decreased over time in those with low MT practice time, but increased in those with high practice time. Higher MT practice time also corresponded to lower levels of negative affect and higher levels of positive affect (indexed by the Positive and Negative Affect Schedule). The relationship between practice time and negative, but not positive, affect was mediated by WMC, indicating that MT-related improvements in WMC may support some but not all of MT's salutary effects. Nonetheless, these findings suggest that sufficient MT practice may protect against functional impairments associated with high-stress contexts.
Dynamic adjustments in cognitive control are well documented in conflict tasks, wherein competition from irrelevant stimulus attributes intensifies selection demands and leads to subsequent performance benefits. The current study investigated whether mnemonic demands, in a working memory (WM) task, can drive similar online control modifications. Demand levels (high vs. low) of WM maintenance (memory load of 2 items vs. 1 item) and delay-spanning distractor interference (confusable vs. not confusable with memoranda) were manipulated using a factorial design during a WM delayed-recognition task. Performance was best subsequent to trials in which both maintenance and distractor interference demands were high, followed by trials with high demand in either of these 2 control domains, and worst following trials with low demand in both domains. These results suggest that dynamic adjustments in cognitive control are not triggered exclusively by conflict-specific contexts but are also triggered by WM demands, revealing a putative mechanism by which this system configures itself for successful task performance.
Current military deployments have resulted in many psychological and physical health issues and created interest in protective measures to mitigate effects of prolonged and repetitive stress. Mindfulness training has been successfully used for stress reduction in other contexts. The following case report presents a detachment of U.S. Marines who received Mindfulness-Based Mind Fitness Training (MMFT) prior to deployment. Self-report measures of mindfulness, perceptions of stress, predictors of compliance with mindfulness practice, and time spent engaging in practice were indexed. More time spent engaging in practice corresponded with greater self-reported mindfulness; increases in mindfulness were associated with decreases in perceived stress.
Working memory (WM) representations serve as templates that guide behavior, but the neural basis of these templates remains elusive. We tested the hypothesis that WM templates are maintained by biasing activity in sensoriperceptual neurons that code for features of items being held in memory. Neural activity was recorded using event-related potentials (ERPs) as participants viewed a series of faces and responded when a face matched a target face held in WM. Our prediction was that if activity in neurons coding for the features of the target is preferentially weighted during maintenance of the target, then ERP activity evoked by a nontarget probe face should be commensurate with the visual similarity between target and probe. Visual similarity was operationalized as the degree of overlap in visual features between target and probe. A face-sensitive ERP response was modulated by target-probe similarity. Amplitude was largest for probes that were similar to the target, and decreased monotonically as a function of decreasing target-probe similarity. These results indicate that neural activity is weighted in favor of visual features that comprise an actively held memory representation. As such, our findings support the notion that WM templates rely on neural populations involved in forming percepts of memory items.
We investigated whether mindfulness training (MT) influences information processing in a working memory task with complex visual stimuli. Participants were tested before (T1) and after (T2) participation in an intensive one-month MT retreat, and their performance was compared with that of an age- and education-matched control group. Accuracy did not differ across groups at either time point. Response times were faster and significantly less variable in the MT versus the control group at T2. Since these results could be due to changes in mnemonic processes, speed-accuracy trade-off, or nondecisional factors (e.g., motor execution), we used a mathematical modeling approach to disentangle these factors. The EZ-diffusion model (Wagenmakers, van der Maas, & Grasman, Psychonomic Bulletin & Review 14:(1), 3-22, 2007) suggested that MT leads to improved information quality and reduced response conservativeness, with no changes in nondecisional factors. The noisy exemplar model further suggested that the increase in information quality reflected a decrease in encoding noise and not an increase in forgetting. Thus, mathematical modeling may help clarify the mechanisms by which MT produces salutary effects on performance.
This article draws on research in neuroscience, cognitive science, developmental psychology, and education, as well as scholarship from contemplative traditions concerning the cultivation of positive development, to highlight a set of mental skills and socioemotional dispositions that are central to the aims of education in the 21st century. These include self-regulatory skills associated with emotion and attention, self-representations, and prosocial dispositions such as empathy and compassion. It should be possible to strengthen these positive qualities and dispositions through systematic contemplative practices, which induce plastic changes in brain function and structure, supporting prosocial behavior and academic success in young people. These putative beneficial consequences call for focused programmatic research to better characterize which forms and frequencies of practice are most effective for which types of children and adolescents. Results from such research may help refine training programs to maximize their effectiveness at different ages and to document the changes in neural function and structure that might be induced.
Uncontrollable anxious thought characterizes a number of emotional disorders. Little is known, however, about the cognitive mechanisms that underlie the ability to control these thoughts. The present study investigated the extent to which two well-characterized executive control processes--working memory and inhibition--are engaged when an individual attempts to control worry. Participants completed a concurrent assessment of these processes while attempting to control personally-relevant worried and neutral thoughts. To examine the specificity of these effects to attempts to control worry, versus a residual "depletion" effect of having previously engaged in worry, a subset of participants completed the assessment without instructions to control their worried or neutral thoughts. Attempts to control worry engaged working memory and inhibition to a greater extent than did attempts to control neutral thought. This increased engagement was not explained solely by anxious affect, nor was it significantly associated with trait worry. Engagement did not differ by group, suggesting that executive control depletion by worry cannot be dismissed as an alternative explanation of these findings. These results highlight working memory and inhibition as potentially valuable constructs for deepening our understanding of the nature and treatment of worry and its control.
Mindfulness training (MT) is a form of mental training in which individuals engage in exercises to cultivate an attentive, present centered, and non-reactive mental mode. The present study examines the putative benefits of MT in University students for whom mind wandering can interfere with learning and academic success. We tested the hypothesis that short-form MT (7 h over 7 weeks) contextualized for the challenges and concerns of University students may reduce mind wandering and improve working memory. Performance on the sustained attention to response task (SART) and two working memory tasks (operation span, delayed-recognition with distracters) was indexed in participants assigned to a waitlist control group or the MT course. Results demonstrated MT-related benefits in SART performance. Relative to the control group, MT participants had higher task accuracy and self-reported being more "on-task" after the 7-week training period. MT did not significantly benefit the operation span task or accuracy on the delayed-recognition task. Together these results suggest that while short-form MT did not bolster working memory task performance, it may help curb mind wandering and should, therefore, be further investigated for its use in academic contexts.

This dissertation uses a Zen koan as a foundation for discussing teacher training and development. It suggests that teacher training attends to issues of theory, pedagogy, and technology, and it contends that teacher training and development does not adequately attend to the intrapersonal aspect of teaching. In spite of the use of reflective techniques in teacher education, teachers are not trained in a significant way to navigate, negotiate, or manage the issues of identity, the issues of self-belief, the patterns of thought, and/or the emotional patterns, which affect their teaching and their classrooms. This work looks at research regarding the importance of the intrapersonal aspect of teaching in relation to teacher effectiveness and classroom climate; it considers current practices in pre-service and in-service teacher training; and it reviews research related to the efficacy of mindfulness and contemplative practices, such as meditation. It argues that the intrapersonal aspect of teaching is relevant to teacher effectiveness and classroom climate; that contemplative and mindfulness practices may offer systems that support and sustain teachers as they navigate, negotiate, and manage the intrapersonal aspect of teaching; and that pre-service and in-service professional development may provide vehicles to deliver this training.
This thesis examines Tibetan perspectives on the causation, management and treatment of mental illness (Tib.: sems nad) within a Tibetan exile community in Darjeeling, northeast India. Based on two six-month periods of ethnographic fieldwork conducted in 2011 and 2012, it examines common cultural understandings of mental illness and healing, and how these are reflected in health-seeking behaviour. To date, research on lay Tibetan perspectives of mental illness and their impact on health-seeking behaviour has been limited, especially in relation to the concept of smyo nad (‘madness’). Following on from work by Jacobson (2000, 2002, 2007) and Millard (2007), the thesis investigates lay Tibetan perceptions of the causation and treatment of various kinds of mental disorders through the use of indepth semi-structured interviews and participant observation, comparing and contrasting Tibetan approaches to those of biomedical psychology and psychiatry and their accompanying classification systems, the American Diagnostic and Statistical Manual of Mental Disorders (DSM) and European International Classification of Disease (ICD). Four case studies of individuals labelled with different Tibetan and biomedical diagnoses related to mental health conditions are described in order to illustrate a number of key concepts in Tibetan approaches to mental illness and its healing. The research found that that a number of informants successfully combined different – sometimes opposing – explanatory frameworks and treatment approaches in response to an episode of mental illness. However, the thesis concludes that the Tibetan and biomedical categories remain difficult to correlate, due in part to their culturally-specific nature, based on significantly different underlying assumptions regarding individuals and their relationship to the environment.
This chapter concerns a ritual for the consecration of medicines in Ladakh, a region in north-western Himalayan India. It describes not only the sequence and significance of the actions performed by the participants, but also the place of the ritual in the social landscape of twenty-first century Ladakh. While the empowerment of medicine is an age-old practice, this ritual incorporates very contemporary elements. The smandrup (sman sgrub) ritual offers the opportunity to examine and analyse the social encounters between the amchi, social welfare organizations, and the donors involved in the development of the 'science of healing', Sowa rigpa. The field of the ritual associates the forces of the Buddhas with those of foreign donors, thus not only empowering and consecrating the medicines, but also contributing to the revitalization of the medical system as a whole.

Cordyceps sinensis has been described as a medicine in old Chinese medical books and Tibetan medicine. It is a rare combination of a caterpillar and a fungus and found at altitudes above 4500m in Sikkim. Traditional healers and local people of North Sikkim recommend the mushroom, i.e., Yarsa gumba, Keera jhar (C. sinensis) for all diseases either as a single drug or combined with other herbs. The present study was undertaken to collect information regarding the traditional uses of cordyceps in Sikkim. It was found that most local folk healers/traditional healers use cordyceps for the treatment of 21 ailments. A modern literature search was carried out to assess whether the curative effects are valid or just blind faith of local people. Chemical constituents of cordyceps are given and pharmacological and biological studies reviewed. More mechanism-based and disease-oriented clinical studies are recommended.
This paper presentation presents a Buddhist point of view on suffering, illness, health, and their interrelationship. The author outlines what suffering means in Buddhism, shows how this concept can be used to promote both physical and spiritual wellbeing, how meditation is used as the process for this positive actualization, and finally outlines some practical applications, such as Tibetan medicine, as useful to this discussion on suffering and wellbeing. The author shows how, in Buddhism, physical and psychological health are interconnected, and how this may be applied progressively to Western medicine. Copyright belongs to the author.

Traditional herbal preparations (THPs) used in Ayurveda, Traditional Chinese Medicine (TCM), Traditional Tibetan Medicine (TTM) and other Asian traditional medicine systems may contain significant amounts of mercury, arsenic or lead. Though deliberately incorporated in Asian THPs for therapeutic purposes, these constituents have caused intoxications worldwide. The aim of this study was therefore to determine mercury, arsenic and lead levels in Asian THPs on the Dutch market. 292 THPs used in Ayurveda, TCM and TTM were sampled between 2004 and 2007. Samples were mostly multi ingredient THPs containing herbs and minerals. The labeling of less than 20% of the THPs suggested the presence of mercury, arsenic or lead. These elements were shown by ICP-MS in 186 (64%) of 292 THPs. Estimated weekly mercury, arsenic and lead intake levels were calculated for each THP from the analytically determined concentrations and the recommended dose. 59 THPs (20%) were likely to result in intakes of these elements significantly exceeding safety limits. Of these 59 THPs, intake estimates for 50 THPs significantly exceeded the safety limit for mercury (range 1.4 - 1747 mg/wk); intake estimates for 26 THPs significantly exceeded the safety limit for arsenic (range 0.53 - 427 mg/wk) and intake estimates for 8 THPs were significantly above the safety limit for lead (range 2.6 - 192 mg/wk). It is concluded that the mercury, arsenic and lead contents of THPs used in Ayurveda, TCM and TTM remain a cause for concern and require strict control.

The ancient art of Tibetan medicine is a veritable treasure in the world annals of medical science. Tibetan medicine evolved over ages, as the tibeta people accumulated experience struggling against the conditions of the snow plateau, emerging as a unique realm of medicine with a distinct understanding of physiology and pathology and its own methods of diagnosis, treatment and medication. The abundant medicinal herbs that grow on the plateau are the active ingredients in the special medicines Tibetans use to treat patients, which in turn is a precious cultural legacy that is now being passed on to the world. Known for its traditional therapies, Tibetan medicine is remarkably effective and beneficial, and has made great contributions to the overall health of humankind.

There is a prevailing conviction that if traditional medicine (TRM) or complementary and alternative medicine (CAM) are integrated into healthcare systems, modern scientific medicine (MSM) should retain its principal status. This paper contends that this position is misguided in medical contexts where TRM is established and remains vibrant. By reflecting on the Chinese policy on three entrenched forms of TRM (Tibetan, Mongolian and Uighur medicines) in western regions of China, the paper challenges the ideology of science that lies behind the demand that all traditional forms of medicine be evaluated and reformed according to MSM standards. Tibetan medicine is used as a case study to indicate the falsity of a major premise of the scientific ideology. The conclusion is that the proper integrative system for TRM and MSM is a dual standard based system in which both TRM and MSM are free to operate according to their own medical standards.
