There is an overriding orthodoxy amongst philosophers that attention is a ‘unified phenomenon’, subject to explanation by one monistic theory. In this article, I examine whether this philosophical orthodoxy is reflected in the practice of psychology. I argue that the view of attention that best represents psychological work is a variety of conceptual pluralism. When it comes to the psychology of attention, monism should be rejected and pluralism should be embraced. _1_ The Monistic Consensus _2_ The Varieties of Pluralism _3_ (...)

This paper defends a novel view of ‘what it is like’-sentences, according to which they attribute certain sorts of relations—I call them ‘affective relations’—that hold between events and individuals. The paper argues in detail for the superiority of this proposal over other views that are prevalent in the literature. The paper further argues that the proposal makes better sense than the alternatives of the widespread use of Nagel’s definition of conscious states and that it also shows the mistakes in two (...) prominent suggestions about the definition when properly understood: first, that it is empty and uninformative, and second, that it leads directly to a substantial claim in the theory of consciousness, namely that an individual is in a conscious state only if the individual is aware of their being in that state.

Cognitive science is, of course, not really a new discipline, but a recognition of a fundamental set of common concerns shared by the disciplines of psychology, computer science, linguistics, economics, epistemology, and the social sciences generally. All of these disciplines are concerned with information processing systems, and all of them are concerned with systems that are adaptive—that are what they are from being ground between the nether millstone of their physiology or hardware, as the case may be, and the upper (...) millstone of a complex environment in which they exist. Systems that are adaptive may equally well be described as “artificial,” for as environments change, they can be expected to change too, as though they were deliberately designed to fit those environments (as indeed they sometimes are).The task of empirical science is to discover and verify invariants in the phenomena under study. The artificiality of information processing systems creates a subtle problem in defining empirical invariants in such systems. For observed regularities are very likely invariant only within a limited range of variation in their environments, and any accurate statement of the laws of such systems must contain reference to their relativity to environmental features. It is a common experience in experimental psychology, for example, to discover that we are studying sociology—the effects of the past histories of our subjects—when we think we are studying physiology—the effects of properties of the human nervous system. Similarly, business cycle economists are only now becoming aware of the extent to which the parameters of the system they are studying are dependent on the experiences of a population with economic events over the previous generation.In artificial sciences, the descriptive and the normative are never far apart. Thus, in economics, the “principle of rationality” is sometimes asserted as a descriptive invariant, sometimes as advice to decision makers. Similarly, in psychology, the processes of adaptation (learning) have always been a central topic, at one time a topic that dominated the whole field of research. Linguistics, too, has suffered its confusions between descriptive and normative attitudes towards its subject. But we must avoid the error, in studying information processing systems, of thinking that the adaptive processes themselves must be invariant; and we must be prepared to face the complexities of regression in the possibility that they themselves may be subject to improvement and adaptation.It might have been necessary a decade ago to argue for the commonality of the information processes that are employed by such disparate systems as computers and human nervous systems. The evidence for that commonality is now overwhelming, and the remaining questions about the boundaries of cognitive science have more to do with whether there also exist nontrivial commonalities with information processing in genetic systems than with whether men and machines both think.

Consciousness in experimental subjects is typically inferred from reports and other forms of voluntary behaviour. A wealth of everyday experience confirms that healthy subjects do not ordinarily behave in these ways unless they are conscious. Investigation of consciousness in vegetative state patients has been based on the search for neural evidence that such broad functional capacities are preserved in some vegetative state patients. We call this the standard approach. To date, the results of the standard approach have suggested that some (...) vegetative state patients might indeed be conscious, although they fall short of being demonstrative. The fact that some vegetative state patients show evidence of consciousness according to the standard approach is remarkable, for the standard approach to consciousness is rather conservative, and leaves open the pressing question of how to ascertain whether patients who fail such tests are conscious or not. We argue for a cluster-based ‘natural kind’ methodology that is adequate to that task, both as a replacement for the approach that currently informs research into the presence or absence of consciousness in vegetative state patients and as a methodology for the science of consciousness more generally. 1.

Block proposes that phenomenal experience overflows conscious access. In contrast, we propose that conscious access overflows overt report. We argue that a theory of phenomenal experience cannot discard subjective report and that Block's examples of phenomenal relate to two different types of perception. We propose that conscious access is more than simply readout of a pre-existing phenomenal experience.

This paper attempts to begin to answer four questions. 1. What is consciousness? 2. What is the relation of consciousness to the brain? 3. What are some of the features that an empirical theory of consciousness should try to explain? 4. What are some common mistakes to avoid?

The most important scientific discovery of the present era will come when someone -- or some group -- discovers the answer to the following question: How exactly do neurobiological processes in the brain cause consciousness? This is the most important question facing us in the biological sciences, yet it is frequently evaded, and frequently misunderstood when not evaded. In order to clear the way for an understanding of this problem. I am going to begin to answer four questions: 1. What (...) is consciousness? 2. What is the relation of consciousness to the brain? 3. What are some of the features that an empirical theory of consciousness should try to explain? 4. What are some common mistakes to avoid? (shrink)

This paper identifies a form of remembering sufficiently overlooked that it has not yet been dignified with a name. I shall christen it Rilkean Memory. This form of memory is, typically, embodied and embedded. It is a form of involuntary, autobiographical memory that is neither implicit nor explicit, neither declarative nor procedural, neither episodic nor semantic, and not Freudian. While a discussion of the importance of Rilkean memory lies beyond the scope of this paper, I shall try to show that (...) admitting Rilkean memory into our ontology does point us in the direction of a very different conception of the mind and mental processes.

ABSTRACT:Determining the biological function of phenomenal consciousness appears necessary to explain its origin: evolution by natural selection operates on organisms’ traits based on the biological functions they fulfill. But identifying the function of phenomenal consciousness has proven difficult. Some have proposed that the function of phenomenal consciousness is to facilitate mental processes such as reasoning or learning. But mental processes such as reasoning and learning seem to be possible in the absence of phenomenal consciousness. It is difficult to pinpoint in (...) what way phenomenal consciousness enhances these processes or others like them. In this paper, we explore a possibility that has been neglected to date. Perhaps phenomenal consciousness has no function of its own because it is either a by-product of other traits or a (functionless) accident. If so, then phenomenal consciousness has an evolutionary explanation even though it fulfills no biological function. (shrink)

Contrary to Block's assertion, “identity-crowding” does not provide an interesting instance of object-seeing without object-attention. The successful judgments and unusual phenomenology of identity-crowding are better explained by unconscious perception and non-perceptual phenomenology associated with cognitive states. In identity-crowding, as in other cases of crowding, subjects see jumbled textures and cannot individuate the items contributing to those textures in the absence of attention. Block presents an attenuated sense in which identity-crowded items are seen, but this is irrelevant to the debate about (...) phenomenal experience of an object in the absence of object-attention. Finally, even unconscious object perception in identity-crowding likely involves an attention-like selective process. (shrink)

Can unattended objects by seen? Ned Block has claimed they can on the basis of “identity-crowding.” This paper summarizes the ensuing debate with particular emphasis on the role of unconscious perception. Although unconscious perception plays an important role, it cannot support conscious object-seeing in identity-crowding. Nevertheless, unconscious perception assists in making successful judgments about unseen objects. Further, compelling conceptual evidence against seeing unattended objects places the burden of proof on Block. I argue that countability is necessary for seeing objects and (...) sufficient for attention to them; thus, no unattended objects are seen. (shrink)

Working Memory plays a crucial role in many high-level cognitive processes . The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside (...) of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM. (shrink)

Subliminal perception (SP) is today considered a well-supported theory stating that perception can occur without conscious awareness and have a significant impact on later behaviour and thought. In this article, we first present and discuss different approaches to the study of SP. In doing this, we claim that most approaches are based on a dichotomic measure of awareness. Drawing upon recent advances and discussions in the study of introspection and phenomenological psychology, we argue for both the possibility and necessity of (...) using an elaborated measure of subjective states. In the second part of the article, we present findings where these considerations are implemented in an empirical study. The results and implications are discussed in detail, both with reference to SP, and in relation to the more general problem of using elaborate introspective reports as data in relation to studies of cognition.

A familiar and enduring controversy surrounds the question of whether our phenomenal experience “overflows” availability to cognition: do we consciously see more than we can remember and report? Both sides to this debate have long sought to move beyond naïve appeals to introspection by providing empirical evidence for or against overflow. Recently, two notable studies—Bronfman, Brezis, Jacobson, and Usher and Vandenbroucke, Sligte, Fahrenfort, Ambroziak, and Lamme —have purported to provide compelling evidence in favor of overflow. Here I explain why the (...) data from both studies are wholly consistent with a “no overflow” interpretation. Importantly, when framed purely in representational or informational terms, this “no overflow” interpretation agrees with the interpretations respectively offered by both Bronfman et al. and Vandenbroucke et al.. The difference only emerges when additional assumptions are made concerning which representations correspond to elements in consc.. (shrink)

Consciousness has a peculiar affinity for presence; conscious states represent their contents as now. To understand how conscious states come to represent time in this way, we need a distinction between a mental state that represents now and one that simply occurs now. A teleofunctional theory accounts for the distinction in terms of the development and function of explicit temporal representation. The capacity to represent a situation explicitly as ‘now’ and compare it with past situations in order to prepare for (...) the future involves the separation of goals from the particular action required to attain them. That is, when a creature is able to consider alternative paths of action, it becomes necessary to conceive of alternate future times as distinct from the present moment. The developmental, functional approach of a teleofunctional theory is promising in its ability to integrate research from diverse empirical fields for support of its claims. (shrink)

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention, working memory, and episodic memory retrieval. Several recent fMRI studies have also reported fronto-parietal activity during conscious visual perception. A major goal of this review was to assess the degree of anatomical overlap among activation patterns associated with these four functions. A second goal was to shed light on the possible cognitive relationship of processes that relate to common brain activity across functions. For all reviewed functions we (...) observed a consistent and overlapping pattern of brain activity. The overlap was most pronounced for the bilateral parietal cortex , and dorsolateral prefrontal cortex . The common fronto-parietal activity will be discussed in terms of processes related to integration of distributed representations in the brain. (shrink)

Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situation is getting confusing because some theorists formulate their models without making reference to existing views, redundantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of self-focus, amount (...) of self-related information, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extended, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in relation to mirror self-recognition and language.

A response to Christof Koch and Naotsugu Tsuchiya's 'Attention and Consciousness: Two Distinct Brain Processes'.

Biological knowledge does not fit the image of science that philosophers have developed. Many argue that biology has no laws. Here I criticize standard normative accounts of law and defend an alternative, pragmatic approach. I argue that a multidimensional conceptual framework should replace the standard dichotomous law/ accident distinction in order to display important differences in the kinds of causal structure found in nature and the corresponding scientific representations of those structures. To this end I explore the dimensions of stability, (...) strength, and degree of abstraction that characterize the variety of scientific knowledge claims found in biology and other sciences.

A broad range of evidence regarding the functional organization of the vertebrate brain – spanning from comparative neurology to experimental psychology and neurophysiology to clinical data – is reviewed for its bearing on conceptions of the neural organization of consciousness. A novel principle relating target selection, action selection, and motivation to one another, as a means to optimize integration for action in real time, is introduced. With its help, the principal macrosystems of the vertebrate brain can be seen to form (...) a centralized functional design in which an upper brain stem system organized for conscious function performs a penultimate step in action control. This upper brain stem system retained a key role throughout the evolutionary process by which an expanding forebrain – culminating in the cerebral cortex of mammals – came to serve as a medium for the elaboration of conscious contents. This highly conserved upper brainstem system, which extends from the roof of the midbrain to the basal diencephalon, integrates the massively parallel and distributed information capacity of the cerebral hemispheres into the limited-capacity, sequential mode of operation required for coherent behavior. It maintains special connective relations with cortical territories implicated in attentional and conscious functions, but is not rendered nonfunctional in the absence of cortical input. This helps explain the purposive, goal-directed behavior exhibited by mammals after experimental decortication, as well as the evidence that children born without a cortex are conscious. Taken together these circumstances suggest that brainstem mechanisms are integral to the constitution of the conscious state, and that an adequate account of neural mechanisms of conscious function cannot be confined to the thalamocortical complex alone.

Both Marya Schechtman and Galen Strawson appeal to autobiographical memory in developing their accounts of personal identity. Although both scholars share a similar conception of autobiographical memory, they use it to develop theories of personal identity that are radically distinct. Memories that are relevant for personal identity are generally considered to be personal (autobiographical) memories of those events in one’s lifetime to which one can gain first-personal access: memories from-the-inside. Both Schechtman and Strawson base their discussion of personal identity on (...) exactly this type of memory. Empirical evidence shows, however, that personal memory imagery is not only visualised from-the-inside, from a “field” perspective. Personal memories may also involve “observer” perspectives, in which one sees oneself from-the-outside in the remembered scene. Both Schechtman and Strawson appeal to the notion of remembering from-the-inside, but they remain silent on the phenomenon of observer perspectives in personal memory. I suggest that accounts of personal identity that appeal to memory should consider observer perspectives as one aspect of personal memory. I explore the implications that the acknowledgment and inclusion of observer perspectives would have for both Schechtman’s and Strawson’s accounts. Even though autobiographical memory is not their theoretical target, both Schechtman and Strawson base their accounts of personal identity on their understanding of autobiographical memory. Therefore, their depictions of the nature of personal identity are founded upon an incomplete picture of autobiographical memory. (shrink)

I give an account of the difference between "Holistic" and "Atomistic" views of conscious experience. On the Holistic view, we enjoy a unified "field" of awareness, whose parts are mere modifications of the whole, and therefore owe their existence to the whole. There is some tendency to saddle those who reject the Holistic field model with a (perhaps) implausible "building block" view. I distinguish a number of different theses about the parts of an experience that are suggested by the "building (...) block" metaphor, but which can be rejected by those who also reject the holistic field view.

The view I've been defending in the theory of justification I have termed ‘propositionalism’. It counsels beginning inquiry into the nature of justification by adopting a particular form of evidentialism, according to which the first task is to describe the abstract relation of evidencing that holds between propositional contents. Such an approach has a variety of implications for the theory of justification itself, and many of the motivations for the view are of a standard internalist variety. Some of these motivations (...) will be described in due course, but there is also a further motivation to mention here as well. Such a theory, beyond enabling a theory to satisfy typical internalist strictures, also allows a strong relationship between the theory of justification and more standard confirmation theory where claims are confirmed and disconfirmed by information gleaned from experiments and other sources. It is a natural and pleasing result if confirmation theory can be embedded within the theory of justification developed in the context of more traditional epistemology. (shrink)

Disputes about what is phenomenologically manifest in conscious experience have a way of leading to deadlocks with remarkable immediacy. Disputants reach the foot-stomping stage of the dialectic more or less right after declaring their discordant views. It is this fact, I believe, that leads some to heterophenomenology and the like attempts to found Consciousness Studies on purely third-person grounds. In this paper, I explore the other possible reaction to this fact, namely, the articulation of methods for addressing phenomenological disputes. I (...) suggest two viable methods, of complementary value, which I call “the method of contrast” and “the method of knowability.”. (shrink)

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)
