<p>In the past two decades, the familiar experience of attention - the emphasis on a particular mental activity so that it "fills the mind" - has been subjected to much scientific inquiry. David LaBerge now provides a systematic view of the attention process as it occurs in everyday perception, thinking, and action. Drawing from a variety of research methods and findings from cognitive psychology, neurobiology, and computer science, he presents a masterful synthesis of what is understood about attentional processing. LaBerge explores how we are able to restrict the input of extraneous and confusing information, or prepare to process a future stimulus, in order to take effective action. As well as describing the pathways in the cortex presumed to be involved in attentional processing, he examines the hypothesis that two subcortical structures, the superior colliculus and the thalamus, contain circuit mechanisms that embody an algorithm of attention. In addition, he takes us through various ways of posing the problem, from an information-processing description of how attention works to a consideration of some of the cognitive and behavioral consequences of the brain's computations, such as desiring, judging, imaging, and remembering. Attentional Processing is a highly sophisticated integration of contributions from several fields of neuroscience. It brings together the latest efforts to solve the puzzle of attention: how it works, how it is modulated, what its benefits are, and how it is expressed in the brain.</p>

Meditation can be conceptualized as a family of complex emotional and attentional regulatory training regimes developed for various ends, including the cultivation of well-being and emotional balance. Among these various practices, there are two styles that are commonly studied. One style, focused attention meditation, entails the voluntary focusing of attention on a chosen object. The other style, open monitoring meditation, involves nonreactive monitoring of the content of experience from moment to moment. The potential regulatory functions of these practices on attention and emotion processes could have a long-term impact on the brain and behavior.

We conducted assessments of 28 children with impaired vision (VI group), with ages ranging from 12 to 17 years, and an equal number of age-matched, normal-sighted children (NS group). The VI group had significantly higher rates of breathing, heart rates, and diastolic blood pressure values compared to the NS group (Mann–Whitney U test). Twenty-four of the VI group formed pairs matched for age and degree of blindness, and we randomly assigned members of the pairs to two groups, viz., yoga and physical activity. Both groups spent an hour each day practicing yoga or working in the garden, depending on their group. After 3 weeks, the yoga group showed a significant decrease in breath rate (Wilcoxon paired signed ranks test). There was no change after the physical activity program. The results showed that children with visual impairment have higher physiological arousal than children with normal sight, with a marginal reduction in arousal following yoga.

<p>Drawing its main source of inspiration from a naturalized interpretation of Husserlian phenomenology, On Becoming Aware: A Pragmatics of Experiencing attempts to examine closely the nature of experience and how we may become aware of our own mental life. The authors also focus on how this project fits into the larger context of cognitive science, psychology, neurosciences, and philosophy. Additional partners in the effort to better understand experience are the contemplative systems of the world's spiritual or wisdom traditions, including particularly that of Buddhism. The book includes three separate glossaries of technical terms in phenomenology, the cognitive sciences, and Tibetan Buddhism. The book On Becoming Aware seeks a disciplined and practical approach to exploring human experience. While much of the book draws its inspiration from the phenomenological theories of Husserl, other approaches to the direct study of experience are also explored in depth. One of these approaches is embodied by the world's spiritual or wisdom or contemplative traditions such as Sufism, Buddhism, the Philokalia tradition, and others. Collectively, these traditions have come upon a variety of their own insights and methods for understanding experience, or, to use words from the phenomenological tradition, has developed its own ways of phenomenological reduction Amongst the various wisdom traditions, the authors focus mainly on Buddhism. The authors give an introduction to Buddhist theory and history, followed by an in-depth discussion of the Buddhist contemplative practices of mindfulness, śamatha, vipaśyanā, tonglen (gtong len), lojong (blo sbyong), dzokchen (rdzogs chen), and mahāmudrā. The authors then relate this discussion to themes from philosophy and phenomenology explored earlier in the book, paricularly Husserl's concept of épochè. (Zach Rowinski 2005-01-17) Publisher's description: This book searches for the sources and means for a disciplined practical approach to exploring human experience. The spirit of this book is pragmatic and relies on a Husserlian phenomenology primarily understood as a method of exploring our experience. The authors do not aim at a neo-Kantian a priori ‘new theory’ of experience but instead they describe a concrete activity: how we examine what we live through, how we become aware of our own mental life. The range of experiences of which we can become aware is vast: all the normal dimensions of human life (perception, motion, memory, imagination, speech, everyday social interactions), cognitive events that can be precisely defined as tasks in laboratory experiments (e.g., a protocol for visual attention), but also manifestations of mental life more fraught with meaning (dreaming, intense emotions, social tensions, altered states of consciousness). The central assertion in this work is that this immanent ability is habitually ignored or at best practiced unsystematically, that is to say, blindly. Exploring human experience amounts to developing and cultivating this basic ability through specific training. Only a hands-on, non-dogmatic approach can lead to progress, and that is what animates this book.</p>

Many of us go through our daily lives on autopilot, not fully aware of our conscious experiences. In a discussion moderated by Steve Paulson, executive producer and host of To the Best of Our Knowledge, neuroscientists Richard Davidson and Amishi Jha and clinical mindfulness expert Jon Kabat-Zinn explore the role of consciousness in mental and physical health, how we can train our minds to be more flexible and adaptable, and cutting-edge neuroscience findings about the transformation of consciousness through mindfulness and contemplative practice. The following is an edited transcript of the discussion that occurred February 6, 2013, 7:00-8:15 PM, at the New York Academy of Sciences in New York City.

<p>Mindfulness is an attribute of consciousness long believed to promote well-being. This research provides a theoretical and empirical examination of the role of mindfulness in psychological well-being. The development and psychometric properties of the dispositional Mindful Attention Awareness Scale (MAAS) are described. Correlational, quasi-experimental, and laboratory studies then show that the MAAS measures a unique quality of consciousness that is related to a variety of well-being constructs, that differentiates mindfulness practitioners from others, and that is associated with enhanced self-awareness. An experience-sampling study shows that both dispositional and state mindfulness predict self-regulated behavior and positive emotional states. Finally, a clinical intervention study with cancer patients demonstrates that increases in mindfulness over time relate to declines in mood disturbance and stress.</p>

<p>Enhancing body awareness has been described as a key element or a mechanism of action for therapeutic approaches often categorized as mind-body approaches, such as yoga, TaiChi, Body-Oriented Psychotherapy, Body Awareness Therapy, mindfulness based therapies/meditation, Feldenkrais, Alexander Method, Breath Therapy and others with reported benefits for a variety of health conditions. To better understand the conceptualization of body awareness in mind-body therapies, leading practitioners and teaching faculty of these approaches were invited as well as their patients to participate in focus groups. The qualitative analysis of these focus groups with representative practitioners of body awareness practices, and the perspectives of their patients, elucidated the common ground of their understanding of body awareness. For them body awareness is an inseparable aspect of embodied self awareness realized in action and interaction with the environment and world. It is the awareness of embodiment as an innate tendency of our organism for emergent self-organization and wholeness. The process that patients undergo in these therapies was seen as a progression towards greater unity between body and self, very similar to the conceptualization of embodiment as dialectic of body and self described by some philosophers as being experienced in distinct developmental levels.</p>

The experience of aversion is shaped by multiple physiological and psychological factors including one's expectations. Recent work has shown that expectancy manipulation can alter perceptions of aversive events and concomitant brain activation. Accruing evidence indicates a primary role of altered expectancies in the placebo effect. Here, we probed the mechanism by which expectation attenuates sensory taste transmission by examining how brain areas activated by misleading information during an expectancy period modulate insula and amygdala activation to a highly aversive bitter taste. In a rapid event-related fMRI design, we showed that activations in the rostral anterior cingulate cortex (rACC), orbitofrontal cortex (OFC), and dorsolateral prefrontal cortex to a misleading cue that the taste would be mildly aversive predicted decreases in insula and amygdala activation to the highly aversive taste. OFC and rACC activation to the misleading cue were also associated with less aversive ratings of that taste. Additional analyses revealed consistent results demonstrating functional connectivity among the OFC, rACC, and insula. Altering expectancies of upcoming aversive events are shown here to depend on robust functional associations among brain regions implicated in prior work on the placebo effect.

Biological systems are particularly prone to variation, and the authors argue that such variation must be regarded as important data in its own right. The authors describe a method in which individual differences are studied within the framework of a general theory of the population as a whole and illustrate how this method can be used to address three types of issues: the nature of the mechanisms that give rise to a specific ability, such as mental imagery; the role of psychological or biological mediators of environmental challenges, such as the biological bases for differences in dispositional mood; and the existence of processes that have nonadditive effects with behavioral and physiological variables, such as factors that modulate the response to stress and its effects on the immune response.

<p>Professor George has ventured into a comparatively unchartered area seeking, as he does, to explore the art and concept of performance in Buddhism -- more specially in the context of Buddhist meditation and theatre. Spelling out the epistemology of performance in all its different connotations and definitional nuances, his study opens out an astonishingly vast panorama of the Buddhist theatrical practices in Sri Lanka, China, Japan, Nepal, Tibet . . . and goes on to demonstrate how, within this panorama, three kinds of theatrical practice can be identified, each corresponding to one of the three paths open to a Buddhist: the karma path, the Bodhisattva option, and enlightenment, and each representative of one of the three main cultures of Buddhism -- the Hinayana, Mahayana, Vajrayana. Supported by extensive endnotes and bibliographic references, Dr. George's book also carries a range of case studies of the art of performance in Buddhism, with definitive examples, among others, of the Sri Lankan Kandy dance and Karma drama, Tibetan Chams and Chod, and Japanese Noh.</p>

Background and objectives. Cancer-related cognitive impairment has been acknowledged as a substantial limiting factor in quality of life among cancer patients and survivors. In addition to deficits on behavioral measures, abnormalities in neurologic structure and function have been reported. In this paper, we review findings from the literature on cognitive impairment and cancer, potential interventions, meditation and cognitive function, and meditation and cancer. In addition, we offer our hypotheses on how meditation practice may help to alleviate objective and subjective cognitive function, as well as the advantages of incorporating a meditation program into the treatment of cancer patients and survivors for cancer-related cognitive deficits. Findings. Various factors have been hypothesized to play a role in cancer-related cognitive impairment including chemotherapy, reduced hormone levels, proinflammatory immune response, fatigue, and distress. Pharmacotherapies such as methylphenidate or modafinil have been suggested to alleviate cognitive deficits. While initial reports suggest they are effective, some pharmacotherapies have side effects and may not relieve other symptoms associated with multimodal cancer treatment including sleep disturbance, nausea and pain. Several recent studies investigating the effects of meditation programs have reported behavioral and corresponding neurophysiological modulations that may be particularly effective in alleviating cancer-related cognitive impairment. Such programs also have been shown to reduce stress, fatigue, nausea and pain, and improve mood and sleep quality. Conclusions. With the increasing success of cancer treatment and the ability to return to previous family, social, and work activities, symptom management and quality of life are an essential part of survivorship. We propose that meditation may help to improve cancer-related cognitive dysfunction, alleviate other cancer-related sequelae, and should be fully investigated as an adjuvant to cancer treatment.

Despite the call for multilevel observation of negative affect, including multiple physiological systems, too little empirical research has been conducted in infants and young children, and physiology-affect associations are not consistently reported. We examined changes in heart rate, respiratory sinus arrhythmia, and preejection period in 24-month-olds across four increasingly challenging, emotion-eliciting tasks. We predicted that changes in cardiac reactivity would be systematically related to changes in negative affect. Results largely support the predictions with one important exception. With increasing distress across the tasks, HR increased and RSA decreased. However, no significant changes in PEP were observed. HR was associated with negative affect during all tasks, and changes in HR were related to changes in negative affect. PEP and negative affect were associated, but only marginally so. Within-subject analyses confirmed the predicted associations. Finally, the associations between physiology and negative affect were different for boys and girls. We discuss these results in the context of implications for future research on cardiac-affect associations in young children.
