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.

There are many facets to mental life and mental experience. In this chapter, I attempt to account for some central characteristics among those facets. I argue that normative function and representation are emergent in particular forms of the self-maintenance of far from thermodynamic equilibrium systems in their essential far-from-equilibrium conditions. The nature of representation that is thereby modeled.

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)

David Rosenthal is a well-known defender of a particular kind of theory of consciousness known as the higher-order thought theory (HOTT). Higher-order theories are united by what Rosenthal calls the Transitivity Principle (TP), which states that a mental state is conscious iff one is conscious of oneself, in some suitable way, as being in that mental state. Since there are various ways to implement TP and HOTT commits one to the view that any mental state could occur unconsciously it seems (...) to predict that a mental state’s being conscious doesn’t have any significant function to perform. An unconscious mental state, according to the theory, has most of its causal connections already, as evidenced by priming studies, subliminal perception, and other empirical findings. Given this, one early objection to HOTT was to emphasize this consequence of the theory. Since consciousness does have a function any theory which predicts that it doesn’t must be suspect. Rosenthal’s primary goal in this paper is to defend HOTT against this objection. In fact he argues that if we could establish that consciousness has no function independently of HOTT we would then have an analogous argument for it: Since consciousness doesn’t have any significant function any theory which predicts that it doesn’t fares be.

The naturalistic voluntary control (VC) theory explains free will and consciousness in terms of each other. It is central to free voluntary control of action that one can control both what one is conscious of, and also what one is not conscious of. Furthermore, the specific cognitive ability or skill involved in voluntarily controlling whether information is processed consciously or unconsciously can itself be used to explain consciousness. In functional terms, it is whatever kind of cognitive processing occurs when a (...) conscious state is voluntarily chosen. This leads to a bivalent view of cognitive processing in which there is voluntary choice either of non-routine (conscious) or routine (unconscious) kinds of processing. On this VC account, consciousness could not exist without its being possible to voluntarily choose a non-routine kind of processing. (shrink)

Journal of Mind and Behavior 28 no. 2 (2007), pp. 135-156. The self-prompting theory of consciousness holds that conscious perceptual experience occurs when non-routine perceptual data prompt the activation of a plan in an executive control system that monitors perceptual input. On the other hand, routine, non-conscious perception merely provides data about the world, which indicatively describes the world correctly or incorrectly. Perceptual experience instead involves data that are about the perceiver, not the world. Their function is that of imperatively (...) prompting the perceiver herself to do something (hence. (shrink)

Todd Moody’s Zombie Earth thought experiment is an attempt to show that ‘conscious inessentialism’ is false or in need of qualification. We defend conscious inessentialism against his criticisms, and argue that zombie thought experiments highlight the need to explain why consciousness evolved and what function(s) it serves. This is the hardest problem in consciousness studies.

The problem of knowledge has been centred around the study of the content of our consciousness, seeing the world through internal representation, without any satisfactory account of the operations of nature that would be a pre-condition for our own performances in terms of concept efficiency in organizing action externally. If we want to better understand where and how meaning fits in nature, we have to find the proper way to decipher its organization, and account for the fact that we have (...) found codes and replicators operating at a deep levels of analysis. Informational analysis deals with units of organizational stability but it takes them for granted and leaves open the question of their origin. Patterns are used when we recognize the same configurations at different places and try to explain through their recurrence, yet to make sense of the presence of signals and counter-balancing mechanisms disseminated in nature, a hypothesis is offered to the effect that feedback signals would have a role to play in the coming about of a world that is open to new configurations and submitted to a form of stability that is more attuned to system laws than overarching unrevisable ones.

DAVID HODGSON Abstract: This article supports the proposition that, if a judgment about the aesthetic merits of an artistic object can take into account and thereby be influenced by the particular quality of the object, through gestalt experiences evoked by the object, then we have free will. It argues that it is probable that such a judgment can indeed take into account and be influenced by the particular quality of the object through gestalt experiences evoked by it, so as to (...) make it probable that we do have free will. The proposition is supported by reference to two basic tricks apparently involved in conscious processes, which I call the qualia trick and the chunking trick; and it is suggested that these tricks make possible and indeed probable the existence of a third trick, which I call the selection trick.

It is the ambition of evolutionary psychology to explain how the basic features of human mental life came to be selected because of their contribution to biological survival. Counted among the most basic must be the subjective qualities of conscious sensory experience: the felt redness we experience on looking at a ripe tomato, the felt saltiness on tasting an anchovy, the felt pain on being pricked by a thorn. But, as many theorists acknowledge, with these qualia, the ambition of evolutionary (...) psychology may have met its match. Everyone agrees that a trait can only contribute to an organism's biological survival in so far as it operates in the public domain. Yet almost everyone also agrees that the subjective quality of sensory experience is (at least for all practical purposes) private and without external influence. Then, maybe we must either concede that the subjective quality of sensations cannot after all have been determined by selection (even if this is theoretically depressing) or else demonstrate that the quality of sensations is not as private as it seems to be (even if this is intuitively unconvincing). No. I believe neither of these solutions to the puzzle is in fact the right one. I argue instead that the truth is that the quality of sensations has indeed been shaped by selection in the past, despite the fact that it is today effectively private. And this situation has come about as a result of a remarkable evolutionary progression, whereby the primitive activity of sensing slowly became "privatized" - that is to say, removed from the domain of overt public behavior and transformed into a mental activity that is now, in humans, largely if not exclusively internal to the subject's mind.

Reflexive consciousness evolved in the context of early human social life, as a means by which 'natural psychologists' could develop working models of their own and others' minds.

This volume is a guide to two types of transcendence of academic borders which seem necessary for understanding and modelling brain function.

In this paper, a theoretical account of the functional role of consciousness in the cognitive system of normal subjects is developed. The account is based upon an approach to consciousness that is drawn from the phenomenological tradition. On this approach, consciousness is essentially peripheral self-awareness, in a sense to be duly explained. It will be argued that the functional role of consciousness, so construed, is to provide the subject with just enough information about her ongoing experience to make it possible (...) for her to easily obtain as much information as she may need. The argument for this account of consciousness' functional role will proceed in three main stages. First, the phenomenological approach to consciousness as peripheral self-awareness will be expounded and endorsed. Second, an account of the functional role of peripheral perceptual awareness will be offered. Finally, the account of the functional role of peripheral self-awareness will be obtained by straightforward extension from the functional role of peripheral perceptual awareness. (shrink)

People have intuitively assumed that many acts of volition are not influenced by unconscious information. However, the available evidence suggests that under suitable conditions, unconscious information can influence behavior and the underlying neural mechanisms. One possibility is that stimuli that are consciously perceived tend to yield strong signals in the brain, and this makes us think that consciousness has the function of sending such strong signals. However, if we could create conditions where the stimuli could produce strong signals but not (...) the conscious experience of perception, perhaps we would find that such stimuli are just as effective in influencing volitional behavior.

The question of whether conscious experience has any functional purpose depends on a more fundamental issue concerning the nature of conscious experience. In particular, whether the world of experience is the external world itself, as suggested by direct realism, or whether it is merely a virtual- reality replica of that world in an internal representation, as in indirect realism, or representationalism. There is an epistemological problem with the notion of direct realism, for we cannot be consciously aware of objects beyond (...) the sensory surface. Therefore the world of experience can only be an internal replica of the external world. This in turn validates a phenomenological approach to studying the nature of the perceptual representation in the brain. Phenomenology reveals that the representational strategy employed in the brain is an analogical one, in which objects are represented in the brain by constructing full spatial replicas of those objects in an internal representation.

Compatibilists often think they can afford to be complacent with regard to scientific findings. But there are apparent threats to free will besides determinism. Robert Kane has recently claimed that if consciousness does not initiate action, all accounts of free will go down, compatibilist and incompatibilist. Some cognitive scientists argue that in fact consciousness does not initiate action. In this paper I argue that they are right (though not for the reasons they advance): as a matter of fact consciousness does (...) not initiate action. But, I contend, Kane is wrong in thinking that it follows that we have no free will. I sketch how we might have free will in spite of the finding that consciousness does not initiate action, and remark on the implications for several well-known accounts of responsibility, include Clarke's agent-causal theory and Fischer and Ravizza's reasons-responsiveness account.

In a recent article, George Sher argues that a realistic conception of human agency, which recognizes the limited extent to which we are conscious of what we do, makes the task of specifying a conception of the kind of control that underwrites ascriptions of moral responsibility much more difficult than is commonly appreciated. Sher suggests that an adequate account of control will not require that agents be conscious of their actions; we are responsible for what we do, in the absence (...) of consciousness, so long as our obliviousness is explained by some subset of the mental states constitutive of the agent. In this response, I argue that Sher is wrong on every count. First, the account of moral responsibility in the absence of consciousness he advocates does not preserve control at all; rather, it ought to be seen as a variety of attributionism (a kind of account of moral responsibility which holds that control is unnecessary for responsibility, so long as the action is reflective of the agent’s real self). Second, I argue that a realistic conception of agency, that recognizes the limited role that consciousness plays in human life, narrows the scope of moral responsibility. We exercise control over our actions only when consciousness has played a direct or indirect role in their production. Moreover, we cannot escape this conclusion by swapping a volitionist account of moral responsibility for an attributionist account: our actions are deeply reflective of our real selves only when consciousness has played a causal role in their production.

In this paper, we present an account of phenomenal con- sciousness. Phenomenal consciousness is experience, and the _problem _of phenomenal consciousness is to explain how physical processes.

According to qualia-epiphenomenalism, phenomenal properties are causally inefficacious, they are metaphysically distinct from, and nomologically connected with certain physical properties. The present paper argues that the claim of causal inefficacy undermines any effort to establish the alleged nomological connection. Epiphenomenalists concede that variations of phenomenal properties in the absence of any variation of physical/functional properties are logically possible, however they deny that these variations are nomologically possible. But if such variations have neither causal nor functional consequences, there is no way (...) to detect themanot only in scientific experiments, but also from the first-person perspective. Since neither third- nor first- person evidence can rule out the actual occurrence of such dissociations, the alleged nomological connection between phenomenal and physical properties cannot be established, in principle. As a consequence, the distinction between logical and nomological possibility breaks down and it cannot be ruled out that such dissociations occur in an unlimited number of cases. (shrink)

There is an argument (Medlin, 1967; Place, 1988) whichshows conclusively that if qualia are causallyimpotent we could have no possible grounds forbelieving that they exist. But if, as this argumentshows, qualia are causally potent with respect to thedescriptions we give of them, it is tolerably certainthat they are causally potent in other morebiologically significant respects. The empiricalevidence, from studies of the effect of lesions of thestriate cortex (Humphrey, 1974; Weiskrantz, 1986;Cowey and Stoerig, 1995) shows that what is missing (...) inthe absence of visual qualia is the ability tocategorize sensory inputs in the visual modality. This would suggest that the function of privateexperience is to supply what Broadbent (1971) callsthe evidence on which the categorization ofproblematic sensory inputs are based. At the sametime analysis of the causal relation shows that whatdifferentiates a causal relation from an accidentalspatio-temporal conjunction is the existence ofreciprocally related dispositional properties of theentities involved which combine to make it true thatif one member of the conjunction, the cause, had notexisted, the other, the effect, would not haveexisted. The possibility that qualia might bedispositional properties of experiences which, as itwere, supply the invisible glue that sticks cause toeffect in this case is examined, but finallyrejected.

Recently some philosophers interested in consciousness have begun to turn their attention to the question of what evolutionary advantages, if any, being conscious might confer on an organism. The issue has been pressed in recent dicussions involving David Chalmers, Todd Moody, Owen Flanagan and Thomas Polger, Daniel Dennett, and others. The purpose of this essay is to consider some of the problems that face anyone who wants to give an evolutionary explanation of consciousness. We begin by framing the problem in (...) the context of some current debates. Then we. (shrink)

Higher-order theories of consciousness posit that a mental state is conscious by virtue of being represented by another mental state, which is therefore a higher-order representation (HOR). Whether HORs are construed as thoughts or experiences, higher-order theorists have generally contested whether such metarepresentations have any significant cognitive function. In this paper, I argue that they do, focusing on the value of conscious thinking, as distinguished from conscious perceiving, conscious feeling, and other forms of conscious mentality. A thinking process is constituted (...) by propositional-attitude states, and during conscious thinking some or all of these states would be targeted by HORs. Since cases of nonconscious thinking are widely accepted, the question arises as to the use of representing one's thoughts during thinking. Contra the views of Armstrong and Rolls, I argue that HORs do not facilitate first-order thinking. Rather, I propose that such representations enable reasoning about one's act of thinking, and I give various examples of this sort of metacognition in support of the theory. I further argue that the general correlation between complex thinking and its being conscious is merely due to the fact that assessing one's mental act is particularly useful during such thinking, not because consciousness somehow facilitates first-order inference-making, as folk psychology implies. My view is thus consistent with recent empirical evidence that complex thinking sometimes yields better results when nonconscious. (shrink)

Various hypotheses about the importance of psycho-neural concomitants are reviewed and their implications discussed for the 'easy' and 'hard' problems of consciousness -- especially, as viewed by cognitive and ecological psychology. In Ecological Psychology, where the subjective-objective dichotomy is repudiated, these concepts are without foundation, and are replaced by informed awareness, which is argued to play an important, perhaps, indispensable role in goal- directed actions and thus to have survival value. The significance of informed awareness is illustrated in several real- (...) world goal-directed tasks. (shrink)

Advocates of the computational theory of mind claim that the mind is a computer whose operations can be implemented by various computational systems. According to these philosophers, the mind is multiply realisable because—as they claim—thinking involves the manipulation of syntactically structured mental representations. Since syntactically structured representations can be made of different kinds of material while performing the same calculation, mental processes can also be implemented by different kinds of material. From this perspective, consciousness plays a minor role in mental (...) activity. However, contemporary neuroscience provides experimental evidence suggesting that mental representations necessarily involve consciousness. Consciousness does not only enable individuals to become aware of their own thoughts, it also constantly changes the causal properties of these thoughts. In light of these empirical studies, mental representations appear to be intrinsically dependent on consciousness. This discovery represents an obstacle to any attempt to construct an artificial mind. (shrink)

Investigations of the function of consciousness in human information processing have focused mainly on two questions: (1) where does consciousness enter into the information processing sequence and (2) how does conscious processing differ from preconscious and unconscious processing. Input analysis is thought to be initially "preconscious," "pre-attentive," fast, involuntary, and automatic. This is followed by "conscious," "focal-attentive" analysis which is relatively slow, voluntary, and flexible. It is thought that simple, familiar stimuli can be identified preconsciously, but conscious processing is needed (...) to identify complex, novel stimuli. Conscious processing has also been thought to be necessary for choice, learning and memory, and the organization of complex, novel responses, particularly those requiring planning, reflection, or creativity.

Paradoxically, explorers of the territory of consciousness seem to be studying consciousness out of existence, from inside the field of "consciousness studies". How? Through their love of the phenomenon/process, they have developed powerful single models or lenses through which to understand consciousness. But in doing so, they also seek to destroy the other /equally useful/ lenses. Our opportunity lies in halting the vendettas and cross-speakings/cross-fire. The imploration is to stop the dichotomous thinking and pernicious reification of single models, and instead (...) search for divisions of labor, complementarities, and legitimate redescriptions among the various extant models. In other words, what would happen if we reimagined the conceptual classifications of the various models of consciousness, classifications based on general philosophical dichotomies (e.g., representational/non-representational and individualist/non-individualist), as a variety of compatible and even complementary perspectives on the same complex phenomenon and process? What would happen if rather than dig in our heels vis-à-vis our favorite theory of consciousness, at the exclusion of all the others, we saw our perceived enemy as an actual, indeed necessary, friend-in-waiting? What would it take to see a battlefield as a collaborative opportunity, to see a promising pluralism rather than an endless state space of conflict? (shrink)
