Fractal time fluctuations of the spectral “1/f” form are universal in natural self-organizing systems. Neurobiology is uniquely infused with fractal fluctuations in the form of statistically self-similar clusters or bursts on all levels of description from molecular events such as protein chain fluctuations, ion channel currents and synaptic processes to the behaviors of neural ensembles or the collective behavior of Internet users. It is the thesis of this essay that the brain self-organizes via a vertical collation of these spontaneous events (...) in order to perceive the world and generate adaptive behaviors. REM sleep, which coalesces from self-similar clusters of burst-within-burst behavior during ontogeny, is essential to cognitive-emotional function, and has recurrent fractal organization. Empirical fMRI observations further support the association of fractal fluctuations in the temporal lobes, brainstem and cerebellum during the expression of emotional memory, spontaneous fluctuations of thought and meditative practice. Cognitive-emotional integration arises as amygdaloid-brainstem-cerebellar systems harmonize the vertical “1/f” symphony of coupled isochronous cortical oscillations in the pursuit of mindfulness.

The book uses Zen Buddhism as the opening wedge for an extraordinarily wide-ranging exploration of consciousness.

In this Introduction, I identify seven discrete aspects of attention brought to the fore by by considering the phenomenon of effortless attention: effort, decision-making, action syntax, agency, automaticity, expertise, and mental training. For each, I provide an overview of recent research, identify challenges to or gaps in current attention theory with respect to it, consider how attention theory can be advanced by including current research, and explain how relevant chapters of this volume offer such advances.

This is the first book to explore the cognitive science of effortless attention and action. Attention and action are generally understood to require effort, and the expectation is that under normal circumstances effort increases to meet rising demand. Sometimes, however, attention and action seem to flow effortlessly despite high demand. Effortless attention and action have been documented across a range of normal activities--from rock climbing to chess playing--and yet fundamental questions about the cognitive science of effortlessness have gone largely unasked. (...) -/- This book draws from the disciplines of cognitive psychology, neurophysiology, behavioral psychology, genetics, philosophy, and cross-cultural studies. Starting from the premise that the phenomena of effortless attention and action provide an opportunity to test current models of attention and action, leading researchers from around the world examine topics including effort as a cognitive resource, the role of effort in decision making, the neurophysiology of effortless attention and action, the role of automaticity in effortless action, expert performance in effortless action, and the neurophysiology and benefits of attentional training. -/- Contributors: Joshua M.

Buddhism has captured the imagination of many in the modern (Western) world. Recently, scientists have seemed eager to discover whether claims about Buddhist meditation can be verified experimentally. Brain research is beginning to produce concrete evidence that mental discipline and meditative practice can change the workings of the brain and allow practitioners to achieve different levels of awareness, as measurable for instance in reaction times to stimuli. The goal of this section of articles in Zygon is to address recent developments (...) in this area. The contributions address a wide array of questions, although they certainly do not cover the whole ground of what one may consider “problems” of meditation. Yet, we believe that the issues addressed here have widespread implications and that they constitute a strong argument for the richness of the meditation domain. (shrink)

The information processing capacity of the human mind is limited, as is evidenced by the so-called ‘‘attentional-blink’’ deficit: When two targets (T1 and T2) embedded in a rapid stream of events are presented in close temporal proximity, the second target is often not seen. This deficit is believed to result from competition between the two targets for limited attentional resources. Here we show, using performance in an attentional-blink task and scalp-recorded brain potentials, that meditation, or mental training, affects the distribution (...) of limited brain resources. Three months of intensive mental training resulted in a smaller attentional blink and reduced brain-resource allocation to the first target, as reflected by a smaller T1-elicited P3b, a brain-potential index of resource allocation. Furthermore, those individuals that showed the largest decrease in brain-resource allocation to T1 generally showed the greatest reduction in attentional-blink size. These observations provide novel support for the view that the ability to accurately identify T2 depends upon the efficient deployment of resources to T1. The results also demonstrate that mental training can result in increased control over the distribution of limited brain resources. Our study supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind. (shrink)

I first attempt a taxonomy of meditation in traditional Indian Buddhism. Based on the main psychological or somatic function at which the meditative effort is directed, the following classes can be distinguished: (1) emotion-centered meditation (coinciding with the traditional samatha approach); (2) consciousness-centered meditation (with two subclasses: consciousness reduction/elimination and ideation obliteration); (3) reflection-centered meditation (with two subtypes: morality-directed reflection and reality-directed observation, the latter corresponding to the vipassanā method); (4) visualization-centered meditation; and (5) physiology-centered meditation. In the second part (...) of the essay I tackle the problem of the epistemic validity and happiness-engendering value of Buddhist meditation. In my highly conjectural view, the claim that meditation represents an infallible tool for realizing the (Supreme) Truth as well as a universally valid method for attaining the highest forms of happiness is largely based on the crēdō effect, that is, a placebolike process. I do not deny that meditation may have some positive effects on mental and physical health or that its practice may bring changes to the mind. Meditation may be a valuable alternative approach in life and clinical treatment, but it is far from being a must or a panacea. (shrink)

The Buddhist epistemologist Dharmakīrti (fl. ca. 7th century C.E.) developed a theory of yogic perception that achieved much influence among Buddhist thinkers in India and Tibet. His theory includes an odd problem: on Dharmakīrti’s view, many of the paradigmatic objects of the adept’s meditations do not really exist. How can one cultivate a meditative perception of the nonexistent? This ontological difficulty stems from Dharmakīrti’s decision to construe the Four Noble Truths as the paradigmatic objects of yogic perception. For him, this (...) ontological problem manifests in an epistemological corollary: “impermanence” (anityatā) and other features of the Noble Truths are conceptual, but the adept’s meditative perception of them must be nonconceptual. How can a nonconceptual cognition apprehend a conceptual object? A key aspect of Dharmakīrti’s theory of concepts provides a solution to this problem. Specifically, Dharmakīrti maintains that a concept, when taken as a mental event, can be considered a particular and thus an object of nonconceptual cognition. Taking this approach, Dharmakīrti downplays the notion that yogic perception is an encounter with real things in the world, in part because it is phenomenally akin to hallucination. Instead, what counts for Dharmakīrti—and what differentiates the adept’s realization from the madman’s hallucination—are the salvific effects induced by the meditative experience. (shrink)

Many spiritual traditions employ certain mental techniques (meditation) which consist in inhibiting mental activity whilst nonetheless remaining fully conscious, which is supposed to lead to a realisation of one’s own true nature prior to habitual self-substantialisation. In this paper I propose that this practice can be understood as a special means of becoming aware of consciousness itself as such. To explain this claim I conduct some phenomenologically oriented considerations about the nature of consciousness qua presence and the problem of self-presence (...) of this presence. (shrink)

Can the mind heal the body? The Buddhist tradition says yes--and now many Western scientists are beginning to agree. Healing Emotions is the record of an extraordinary series of encounters between the Dalai Lama and prominent Western psychologists, physicians, and meditation teachers that sheds new light on the mind-body connection. Topics include: compassion as medicine; the nature of consciousness; self-esteem; and the meeting points of mind, body, and spirit. This edition contains a new foreword by the editor.

The thesis of this paper is that the question of whether and how statements of the form 'p and not-p' can have religious meaning in Buddhism can be answered in the affirmative and how in terms of a movement from pre-meditative to meditative state to a post-meditative state in life. The paper focuses on the Diamond Sutra in light of Shigenori Nagatomo's study (Asian Philosophy Vol. 10, No. 3, 2000) and advances an additional line of inquiry. This view emphasises the (...) process in the meditation learning curve from pre-meditative to meditative to post-meditative states that provides the personal religious significance (but not ordinary factual meaning) when the phrase 'A is not A, therefore it is A' is used in the Diamond Sutra.

I am looking at my baby son, as he thrashes around in his crib, two arms flailing, hands grasping randomly, legs kicking the air, head and eyes turning this way and that, a smile followed by a grimace crossing his face. . . And I’m wondering: what is it like to be him? What is he feeling now? What kind of experience is he having of himself?

The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with increased trial-to-trial variability in reaction time and event-related potential deficits during attention tasks. At present, it is unclear whether the ability to sustain attention and its underlying brain circuitry are transformable through training. Here, we show, with dichotic listening task performance and electroencephalography, that training (...) attention, as cultivated by meditation, can improve the ability to sustain atten- tion. Three months of intensive meditation training reduced variability in attentional processing of target tones, as indicated by both enhanced theta-band phase consistency of oscillatory neural responses over anterior brain areas and reduced reaction time variability. Furthermore, those individuals who showed the greatest increase in neural response consistency showed the largest decrease in behav- ioral response variability. Notably, we also observed reduced variability in neural processing, in particular in low-frequency bands, regardless of whether the deviant tone was attended or unattended. Focused attention meditation may thus affect both distracter and target processing, perhaps by enhancing entrainment of neuronal oscillations to sensory input rhythms, a mechanism important for controlling the content of attention. These novel findings highlight the mechanisms underlying focused attention meditation and support the notion that mental training can significantly affect attention and brain function. (shrink)

Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, (...) we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest. (shrink)

These, and many other related questions have continued to rise in the minds of meditation practitioners of Chan, Sôn and Zen Buddhism since the earliest stages in the development of these traditions, and it is in response to such questions that the Sutra of Perfect Enlightenment (Chinese: Yuanjue jing ) was composed. In addition to detailed guidance on the undertaking of Chan contemplation, the sutra offers concise discussions of the fundamental philosophical grounds which underlie such practices, in the form (...) of question and answer sessions between the Buddha and twelve prominent bodhisattvas. While long a popular text throughout the East Asian meditative tradition, the Sutra of Perfect Enlightenment attained to a special canonical status in the Korean Chogye school where it was favored by such luminaries as Chinul, T'aego and Hyujông, and where it is used down to the present day as a basic text for monastic instruction.

Religionists often presuppose that “mysticism” aims at somehow emptying the mind. In the light of evidence, however, meditation seems rather to consist of ritualized action without an explicit emphasis on subjective experience. Boyer & Lienard's (B&L's) theory of ritualized action as “swamping” working memory thus might help explain the effects of meditation without postulating experiential goals the “mystics” obviously do not have. (Published Online February 8 2007).

Mindfulness can be understood as the mental ability to focus on the direct and immediate perception or monitoring of the present moment with a state of open and nonjudgmental awareness. Descriptions of mindfulness and methods for cultivating it originated in eastern spiritual traditions. These suggest that mindfulness can be developed through meditation practice to increase positive qualities such as awareness, insight, wisdom, and compassion. In this article we focus on the relationships between mindfulness, with associated meditation practices, and the cognitive (...) neuroscience of attention and awareness. Mindful awareness is related to distributed attention, phenomenal consciousness, and momentary self-awareness, as characterized by recent findings in cognitive psychology and neuroscience as well as in influential consciousness models. Finally, we outline an integrated neurocognitive model of mindfulness, attention, and awareness, with a key role of prefrontal cortex. (shrink)

Contemporary culture increasingly suffers from problems of attention, over-stimulation, and stress, and a variety of personal and social discontents generated by deceptive body images. This book argues that improved body consciousness can relieve these problems and enhance one’s knowledge, performance, and pleasure. The body is our basic medium of perception and action, but focused attention to its feelings and movements has long been criticized as a damaging distraction that also ethically corrupts through self-absorption. In Body Consciousness, Richard Shusterman refutes such (...) charges by engaging the most influential twentieth-century somatic philosophers and incorporating insights from both Western and Asian disciplines of body-mind awareness.

This article makes five main points. (1) Individual human consciousness is formed in the dynamic interrelation of self and other, and therefore is inherently intersubjective. (2) The concrete encounter of self and other fundamentally involves empathy, under- stood as a unique and irreducible kind of intentionality. (3) Empathy is the precondi- tion (the condition of possibility) of the science of consciousness. (4) Human empathy.

In this single-blind within-subject study, autonomic and EEG variables were compared during 10-min, order-balanced eyes-closed rest and Transcendental Meditation (TM) sessions. TM sessions were distinguished by (1) lower breath rates, (2) lower skin conductance levels, (3) higher respiratory sinus arrhythmia levels, and (4) higher alpha anterior-posterior and frontal EEG coherence. Alpha power was not significantly different between conditions. These results were seen in the first minute and were maintained throughout the 10-min sessions. TM practice appears to (1) lead to a (...) state fundamentally different than eyes-closed rest; (2) result in a cascade of events in the central and autonomic nervous systems, leading to a rapid change in state (within a minute) that was maintained throughout the TM session; and (3) be best distinguished from other conditions through autonomic and EEG alpha coherence patterns rather than alpha power. Two neural networks that may mediate these effects are suggested. The rapid shift in physiological functioning within the first minute might be mediated by a ''neural switch'' in prefrontal areas inhibiting activity in specific and nonspecific thalamocortical circuits. The resulting ''restfully alert'' state might be sustained by a basal ganglia-corticothalamic threshold regulation mechanism automatically maintaining lower levels of cortical excitability. (shrink)

Synaesthesia is considered a rare perceptual capacity, and one that is not capable of cultivation. However, meditators report the experience quite commonly, and in questionnaire surveys, respondents claimed to experience synaesthesia in 35% of meditation retreatants, in 63% of a group of regular meditators, and in 86% of advanced teachers. These rates were significantly higher than in nonmeditator controls, and displayed significant correlations with measures of amount of meditation experience. A review of ancient texts found reports suggestive of synaesthesia in (...) advanced meditators from India and China. These findings suggest that synaesthesia may be cultivated by meditation, and that laboratory studies of meditators could be rewarding. (shrink)
