Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones - such as (...) stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

Explanation does not exist in a metaphysical vacuum. Conceptions of the structure of a phenomenon play an important role in guiding attempts to explain it, and erroneous conceptions of a phenomenon may direct investigation in misleading directions. I believe that there is a case to be made for thinking that much work on the neural underpinnings of consciousness—what is often called the neural correlates of consciousness—is driven by an erroneous conception of the structure of consciousness. The aim of this paper (...) is lay bare some connections between the explanation of consciousness and the structure of consciousness, and to argue for a conception of the structure of consciousness that is more adequate than that which currently drives much research into the neural correlates of consciousness.

I distinguish between two kinds of selection effects on experience: selection of objects or features for experience, and anti-selection of experiences for cognitive uptake. I discuss the idea that both kinds of selection effects can lead to a form of confirmation bias at the level of perception, and argue that when this happens, selection effects can influence the rational role of experience.

This paper explores two kinds of selection effects on perception by the subject’s own psychological states, such as desires, fears, or beliefs. Such states can influence the selection of objects for perceptual experience, or they can influence the selection of perceptual experience for uptake in the process of belief-formation. It is argued that both kinds of selection effects are rationally assessable, even when the subject is not aware of their influence on the selection.

The author recounts some of the early history of what is now known as MBSR, and its relationship to mainstream medicine and the science of the mind/body connection and health. He stresses the importance that MBSR and other mindfulness-based interventions be grounded in a universal dharma understanding that is congruent with Buddhadharma but not constrained by its historical, cultural and religious manifestations associated with its counties of origin and their unique traditions. He locates these developments within an historic confluence of (...) two very different epistemologies encountering each other for the first time, that of science and that of the meditative traditions. The author addresses the ethical ground of MBSR, as well as questions of lineage and of skillful ?languaging? and other means for maximizing the possibility that the value of cultivating mindfulness in the largest sense can be heard and embraced and cultivated in commonsensical and universal ways in secular settings. He directly addresses mindfulness-based instructors on the subject of embodying and drawing forth the essence of the dharma without depending on the vocabulary, texts, and teaching forms of traditional Buddhist environments, even though they are important to know to one degree or another as part of one's own development. The author's perspective is grounded in what the Zen tradition refers to as the one thousand year view. Although it is not stated explicitly in this text, he sees the current interest in mindfulness and its applications as signaling a multi-dimensional emergence of great transformative and liberative promise, one which, if cared for and tended, may give rise to a flourishing on this planet akin to a second, and this time global, Renaissance, for the benefit of all sentient beings and our world.

This essay critiques the standard characterization of mindfulness as present-centred non-judgmental awareness, arguing that this account misses some of the central features of mindfulness as described by classical Buddhist accounts, which present mindfulness as being relevant to the past as well as to the present. I show that for these sources the central feature of mindfulness is not its present focus but its capacity to hold its object and thus allow for sustained attention, regardless of whether the object is present (...) or not. I further show that for these sources mindfulness can be explicitly evaluative, thus demonstrating the degree to which classical Buddhist accounts differ from the modern description of mindfulness as non-judgmental. I conclude that although this modern description may be useful as an operational definition intended for practical instruction, it does not provide an adequate basis for a theoretical analysis of mindfulness, for it fails to emphasize its retentive nature to privilege its alleged nonconceptuality.

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

Buddhism originated and developed in an Indian cultural context that featured many first-person practices for producing and exploring states of consciousness through the systematic training of attention. In contrast, the dominant methods of investigating the mind in Western cognitive science have emphasized third-person observation of the brain and behavior. In this chapter, we explore how these two different projects might prove mutually beneficial. We lay the groundwork for a cross-cultural cognitive science by using one traditional Buddhist model of the mind (...) – that of the five aggregates – as a lens for examining contemporary cognitive science conceptions of consciousness.

Here, we argue that any neurobiological theory based on an experience/function division cannot be empirically confirmed or falsified and is thus outside the scope of science. A ‘perfect experiment’ illustrates this point, highlighting the unbreachable boundaries of the scientific study of consciousness. We describe a more nuanced notion of cognitive access that captures personal experience without positing the existence of inaccessible conscious states. Finally, we discuss the criteria necessary for forming and testing a falsifiable theory of consciousness.

The purpose of this paper is to determine the meaning and function of mindfulness meditation using as the source of inquiry the Pāli Canon, the oldest complete collection of Buddhist texts to survive intact. Mindfulness is the chief factor in the practice of satipa hāna, the best known system of Buddhist meditation. In descriptions of satipa hāna two terms constantly recur: mindfulness (sati) and clear comprehension (sampajañña). An understanding of these terms based on the canonical texts is important not only (...) from a philological angle but because such understanding has major bearings on the actual practice of meditation. The word sati originally meant ‘memory,’ but the Buddha ascribed to this old term a new meaning determined by the aims of his teaching. This meaning, the author holds, might best be characterized as ‘lucid awareness.’ He questions the common explanation of mindfulness as ‘bare attention,’ pointing out problems that lurk behind both words in this expression. He also briefly discusses the role of clear comprehension (sampajañña) and shows that it serves as a bridge between the observational function of mindfulness and the development of insight. Finally, he takes up the question whether mindfulness can legitimately be extracted from its traditional context and employed for secular purposes. He maintains that such non-traditional applications of mindfulness are acceptable and even admirable on the ground that they help alleviate human suffering, but he also cautions against a reductionist understanding of mindfulness and urges that investigators respect the religious tradition in which it is rooted.

One of the most important issues concerning the foundations ofconscious perception centerson thequestion of whether perceptual consciousness is rich or sparse. The overflow argument uses a form of ‘iconic memory’ toarguethatperceptual consciousnessisricher (i.e.,has a higher capacity) than cognitive access: when observing a complex scene we are conscious of more than we can report or think about. Recently, the overflow argumenthas been challenged both empirically and conceptually. This paper reviews the controversy, arguing that proponents of sparse perception are committed to the (...) postulation of (i) a peculiar kind of generic conscious representation that has no independent rationale and (ii) an unmotivated form of unconscious representation that in some cases conflicts with what we know about unconscious representation.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to doubt their (...) authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

This article concerns the interplay between two issues that involve both philosophy and neuroscience: whether the content of phenomenal consciousness is 'rich' or 'sparse', whether phenomenal consciousness goes beyond cognitive access, and how it would be possible for there to be evidence one way or the other.

A renowned philosopher of the mind, also known for his groundbreaking work on Buddhism and cognitive science, Evan Thompson combines the latest neuroscience research on sleep, dreaming, and meditation with Indian and Western philosophy of the mind, casting new light on the self and its relation to the brain. Thompson shows how the self is a changing process, not a static thing. When we are awake we identify with our body, but if we let our mind wander or daydream, we (...) project a mentally imagined self into the remembered past or anticipated future. As we fall asleep, the impression of being a bounded self distinct from the world dissolves, but the self reappears in the dream state. If we have a lucid dream, we no longer identify only with the self within the dream. Our sense of self now includes our dreaming self, the "I" as dreamer. Finally, as we meditate--either in the waking state or in a lucid dream--we can observe whatever images or thoughts arise and how we tend to identify with them as "me." We can also experience sheer awareness itself, distinct from the changing contents that make up our image of the self. Contemplative traditions say that we can learn to let go of the self, so that when we die we can witness its dissolution with equanimity. Thompson weaves together neuroscience, philosophy, and personal narrative to depict these transformations, adding uncommon depth to life's profound questions. Contemplative experience comes to illuminate scientific findings, and scientific evidence enriches the vast knowledge acquired by contemplatives. (shrink)

Attention has been studied in cognitive psychology for more than half a century, but until recently it was largely neglected in philosophy. Now, however, attention has been recognized by philosophers of mind as having an important role to play in our theories of consciousness and of cognition. At the same time, several recent developments in psychology have led psychologists to foundational questions about the nature of attention and its implementation in the brain. As a result there has been a convergence (...) of interest in fundamental questions about attention. This volume presents the latest thinking from the philosophers and psychologists who are working at the interface between these two disciplines. Its fourteen chapters contain detailed philosophical and scientific arguments about the nature and mechanisms of attention; the relationship between attention and consciousness; the role of attention in explaining reference, rational thought, and the control of action; the fundamental metaphysical status of attention, and the details of its implementation in the brain. These contributions combine ideas from phenomenology, neuroscience, cognitive psychology, and philosophy of mind to further our understanding of this centrally important mental phenomenon, and to bring to light the foundational questions that any satisfactory theory of attention will need to address.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the (...) door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

Reading the philosophical literature on consciousness, one might get the idea that there is just one problem in consciousness studies, the hard problem. That would be a mistake. There are other problems; some are more tractable, but none are easy, and all interesting. The literature on the hard problem gives the impression that we have made little progress. Consciousness is just an excuse to work and re-work familiar positions on the mind-body problem. But progress is being made elsewhere. Researchers are (...) moving towards increasingly specific accounts of the neural basis of conscious experience. These efforts will leave some questions unanswered, but they are no less significant for that. (shrink)

Experiences of emotion are content-rich events that emerge at the level of psychological description, but must be causally constituted by neurobiological processes. This chapter outlines an emerging scientific agenda for understanding what these experiences feel like and how they arise. We review the available answers to what is felt (i.e., the content that makes up an experience of emotion) and how neurobiological processes instantiate these properties of experience. These answers are then integrated into a broad framework that describes, in psychological (...) terms, how the experience of emotion emerges from more basic processes. We then discuss the role of such experiences in the economy of the mind and behavior. (shrink)

This paper gives a brief presentation of adverbialism about attention, and explains some of the reasons why it gives an appealing account of attention's metaphysics.
