Attention and Consciousness

Phenomenology and experimental psychology have been largely interested in the same thing when it comes to attention. By building on the work of Aron Gurwitsch, especially his ideas of attention and restructuration, this paper attempts to articulate common ground in psychology and phenomenology of attention through discussion of a new way to think about multistability in some phenomena. What psychology views as an attentionality-intentionality phenomenon, phenomenology views as an intentionality-attentionality phenomenon. The proposal is that an awareness of this restructuring of (...) attentionality and intentionality can benefit both approaches to attention. After reviewing Husserl’s position on attentionality and intentionality, this paper examines multistable phenomena, redefines the attentional transformation called restructuring, discusses disciplinary perspectives on attention and gives an example using common ground.

Attentional character is a way of thinking about what is relevant in a human life, what is meaningful and how it becomes so. This paper introduces the concept of attentional character through a redefinition of attentional capture as achievement. It looks freshly at the attentional capture debate in the current cognitive sciences literature through the lens of Aron Gurwitsch’s gestalt-phenomenology. Attentional character is defined as an initially limited capacity for attending in a given environment and is located within the sphere (...) of attention, primarily as an irrelevant centering in attending.

For the first time, this book classifies how attention shifts, and argues that self-awareness, reflection, and even morality, are best thought of as dynamic...

This article tries to create a bridge of understanding between cognitive scientists and phenomenologists who work on attention. In light of a phenomenology of attention and current psychological and neuropsychological literature on attention, I translate and interpret into phenomenological terms 20 key cognitive science concepts as examined in the laboratory and used in leading journals. As a preface to the lexicon, I outline a phenomenology of attention, especially as a dynamic three-part structure, which I have freely amended from the work (...) of phenomenologist and Gestalt philosopher Aron Gurwitsch (1901–1973). As a conclusion, I discuss the nature of subjectivity in attention and attention research, and whether attention might be the same as consciousness. (shrink)

There is a considerable amount of research being done on attention by cognitive psychologists. I claim that in the process of measuring and mapping consciousness, these researchers have missed important phenomenological findings. After a synopsis and illustration of the nature of attention as described by Aron Gurwitsch, I critique the assumptions of current psychological research on this topic. Included is discussion of the metaphor of attention as a beam or spotlight, the concept of selective attention as the standard accomplishment, and (...) the cognitive bestowal of organization on otherwise unorganized data. It is concluded that cognitive psychologists and others working on attention can benefit from Gurwitsch's work, and that a credible account of attention is crucial to the success of any comprehensive statement on the nature of consciousness.

This article explores the relationship between the bodily presence of other humans in the lived urban world and the experience of everyday architecture. We suggest, from the perspectives of phenomenology and architecture, that being in the company of others changes the way the built environment appears to subjects, and that this enables us to perform simple daily tasks while still attending to the built environment (to a certain, relatively minimal degree). Our analysis shows that in mundane urban settings attending to (...) the environment involves a unique attentional mode, which does not rely on concentrating on, or appreciating the architectural objects, but rather on social attention and on the subject’s kinesthesis in relation to the built environment.

Block argues that relevant data in psychology and neuroscience shows that access consciousness is not constitutively necessary for phenomenality. However, a phenomenal state can be access conscious in two radically different ways. Its content can be access conscious, or its phenomenality can be access conscious. I’ll argue that while Block’s thesis is right when it is formulated in terms of the first notion of access consciousness, there is an alternative hypothesis about the relationship between phenomenality and access in terms of (...) the second notion that is not touched by Block’s argument.

Do we need to attend to an object in order to be conscious of it, and are the objects of our attention necessarily part of our conscious experience? A tight link between attention and consciousness has often been assumed, but it has recently been questioned, on the basis of psychophysical evidence suggesting a double dissociation between top-down attention and consciousness. The present review proposes to consider these issues in the light of time-honored distinctions between exogenous and endogenous forms of attention (...) and between primary and reflective forms of consciousness. These distinctions permit to interpret results from several sources of evidence, including patterns of performance of brain-damaged patients with visual neglect, as suggesting that exogenous attention is a necessary condition for primary visual consciousness to emerge. Visual neglect, which typically results from damage to fronto-parietal networks in the right hemisphere, entails an inability to orient to and to detect contralesional objects. Importantly, neglect patients are not only unable to verbally report contralesional objects, but may also act as if these objects did not exist, for example by bumping into them, thus suggesting an impairment of primary perceptual consciousness. Less frequently, neglect patients may instead show forms of “implicit” knowledge of neglected items, perhaps indicating a deficit of more reflective forms of consciousness, such as those subserving verbal reportability. The integration of several sources of evidence, such as phenomenology, experimental psychology and neuroscience, is needed to further explore the taxonomy of these processes and to identify their neural correlates.

Drawing on the empirical premise that attention makes objects look more intense, Ned Block has argued for mental paint, a phenomenal residue that cannot be reduced to what is perceived or represented. If sound, Block's argument would undermine direct realism and representationism, two widely held views about the nature of conscious perception. We argue that Block's argument fails because the empirical premise it is based upon is false. Attending to an object alters its salience, but not its perceived intensity. We (...) also argue that salience should be equated with mental primer, a close cousin of mental paint that reintroduces difficulties for direct realism and representationism. The upshot is that direct realism and representationism are still in trouble, but not for the reason that Block thinks. (shrink)

Much of recent philosophy of perception is oriented towards accounting for the phenomenal character of perception—what it is like to perceive—in a non-mentalistic way—that is, without appealing to mental objects or mental qualities. In opposition to such views, I claim that the phenomenal character of perception of a red round object cannot be explained by or reduced to direct awareness of the object, its redness and roundness—or representation of such objects and qualities. Qualities of perception that are not captured by (...) what one is directly aware of or by representational content are instances of what Gilbert Harman has called “mental paint” (Block, 1990; Harman, 1990). The claim of this paper is that empirical facts about attention point in the direction of mental paint. The argument starts with the claim (later modified) that when one moves one's attention around a scene while keeping one's eyes fixed, the phenomenology of perception can change in ways that do not reflect which qualities of objects one is directly aware of or the way the world is represented to be. These changes in the phenomenology of perception cannot be accounted for in terms of awareness of or representation of the focus of attention because they manifest themselves in experience as differences in apparent contrast, apparent color saturation, apparent size, apparent speed, apparent time of occurrence and other appearances. There is a way of coping with these phenomena in terms of vague contents, but vague contents cannot save direct realism or representationism because the kind of vagueness required clashes wth the phenomenology itself.

Commentary on Andy Clark's target article on predictive coding.

What does it mean to be a morally good person? It can be tempting to think that it is simply a matter of performing certain actions and avoiding others. And yet there is much more to moral character than our outward actions. We expect a good person to not only behave in certain ways but also to experience the world in certain ways within.

Was wir nicht bemerken können, das können wir auch nicht wahrnehmen: Diese im Rahmen der gegenwärtigen analytischen Philosophie des Geistes weitverbreitete Ansicht wurde neulich von M. Tye und A. Noë verteidigt. Wir werden uns hier mit einigen empirischen Beispielen auseinandersetzen, die u.E. mit dieser Idee kaum in Einklang zu bringen sind und stattdessen den Gedanken nahelegen, dass die Grenzen des Wahrnehmbaren über die Grenzen sowohl des primär Bemerkbaren als auch des sekundär Bemerkbaren hinausgehen. Auf diesem Weg gelangen wir dann zur (...) Verwerfung von Arvidsons Hypothese der Identität zwischen Bewusstseinsfeld und Feld der (im erweiterten Sinne gefassten) Aufmerksamkeit gelangen. (shrink)

In this article, I delineate seven aspects of the process of self-consciousness in order to demonstrate that when any of the aspects is compromised, self-consciousness goes away while consciousness persists. I then suggest that the psychological phenomenon of flow is characterized by a loss of self-consciousness. The seven aspects are: 1) implicit awareness that the person and the self are identical; 2) awareness of an event or circumstance in the world internal or external to the person; 3) awareness that this (...) event or circumstance is not isolated, that something will result from it; 4) inference that a result of the circumstance or event may have an impact on one's person; 5) inference that the impact on one's person may have a normative valence with respect to one's person; 6) inference that the normative valence with respect one's person may be significant to one's person; 7) implicit awareness that any event eventuating in a normative valence that is significant with respect to one's person will also be significant to one's self.

Multisensory processing encompasses all of the various ways in which the presence of information in one sensory modality can adaptively influence the processing of information in a different modality. In Part I of this survey article, I begin by presenting a cartography of some of the more extensively investigated forms of multisensory processing, with a special focus on two distinct types of multisensory integration. I briefly discuss the conditions under which these different forms of multisensory processing occur as well as (...) their important perceptual consequences and interrelations. In Part II, I then turn to examining of some of the different possible ways in which the structure of conscious perceptual experience might also be characterized as multisensory. In addition, I discuss the significance of research on multisensory processing and multisensory consciousness for philosophical attempts to individuate the senses. (shrink)

DETERMINACY is the claim that covert shifts in visual attention sometimes affect the determinacy of visual content (capital letters will distinguish the claim from the familiar word, 'determinacy'). Representationalism is the claim that visual phenomenology supervenes on visual representational content. Both claims are popular among contemporary philosophers of mind, and DETERMINACY has been employed in defense of representationalism. I claim that existing arguments in favor of DETERMINACY are inconclusive. As a result, DETERMINACY-based arguments in support of representationalism are not strong (...) ones. (shrink)

John Campbell investigates how consciousness of the world explains our ability to think about the world; how our ability to think about objects we can see depends on our capacity for conscious visual attention to those things. He illuminates classical problems about thought, reference, and experience by looking at the underlying psychological mechanisms on which conscious attention depends.

It is sometimes said that ordinary linguistic exchange, in ordinary conversation, is a matter of securing and sustaining joint attention. The minimal condition for the success of the conversation is that the participants should be attending to the same things. So the psychologist Michael Tomasello writes, ‘I take it as axiomatic that when humans use language to communicate referentially they are attempting to manipulate the attention of another person or persons.’ I think that this is an extremely fertile approach to (...) philosophical problems about meaning and reference, and in this paper I want to apply it to the case of the first person. So I want to look at the case in which you tell me something about yourself, using the first person, and we achieve joint attention to the same object. But I begin with some remarks about how this approach applies to proper names and to perceptual demonstratives. (shrink)

Proceedings of the Aristotelian Society Supplementary Volume 71 (1997), 55-74, with a reply by Michael Martin.

We argue that Graziano and Kastner are mistaken to claim that neglect favors their self-directed social perception account of consciousness. For the latter should not predict that neglect would result from damage to mechanisms of social perception. Neglect is better explained in terms of damage to attentional mechanisms.

In this paper, I present the discussion between Ayer and Austin about whether sentences or utterances can be incorrigible and I argue in favor of Austin position. I defend Austin against objections from Ayer presented after the publication of Sense & Sensibilia. Unlike what was sustained by Ayer, experiential sentences and material object sentences are not epistemically asymmetrical. A material object sentence can be incorrigible if uttered in appropriated circumstances, and an experiential sentence can be corrigible if uttered in unappropriated (...) circumstances. Relying on Austin position, I argue that self-knowledge does not have any epistemic privilege in relation to knowledge of the external world. These kinds of knowledge equally depend on objective circumstances of the utterance situation. (shrink)

The topic of this paper is the complex interaction between attention, fixation, and one species of change blindness. The two main interpretations of the target phenomenon are the ‘blindness’ interpretation and the ‘inaccessibility’ interpretation. These correspond to the sparse view (Dennett 1991; Tye, 2007) and the rich view (Dretske 2007; Block, 2007a, 2007b) of visual consciousness respectively. Here I focus on the debate between Fred Dretske and Michael Tye. Section 1 describes the target phenomenon and the dialectics it entails. Section (...) 2 explains how attention and fixation weigh in these debates, and argues that Dretske’s hyper-rich view fails precisely because he overlooks certain effects of attention and fixation. Section 3 explains why Tye’s view is also unsatisfying, mainly because he misconceives the degree of access. Section 4 then puts forward the positive model covariance, which has it that the degree of cognitive access tracks the degree of phenomenology, and contrasts it with Block’s view on the Sperling iconic memory paradigm. The paper ends with a discussion of levels of seeing, which involve crowding, indexing, and other visual phenomena. Change ‘blindness’ is a set of phenomena that was discovered about two decades ago, yet an entirely satisfying understanding is still lacking. To move forward, a more detailed understanding of attention and fixation is called for. (shrink)

The overflow debate concerns this following question: does conscious iconic memory have a higher capacity than attention does? In recent years, Ned Block has been invoking empirical works to support the positive answer to this question. The view is called the “rich view” or the “Overflow view”. One central thread of this discussion concerns the nature of iconic memory: for example how rich they are and whether they are conscious. The first section discusses a potential misunderstanding of “visible persistence” in (...) this literature. The second section discusses varieties of attention relevant to this debate. The final section discusses the most prominent alternative interpretation of the Sperling paradigm—the postdiction interpretation—and explains how it can be made compatible with a weaker version of the rich or overflow view.

Not all research in machine consciousness aims to instantiate phenomenal states in artefacts. For example, one can use artefacts that do not themselves have phenomenal states, merely to simulate or model organisms that do. Nevertheless, one might refer to all of these pursuits -- instantiating, simulating or modelling phenomenal states in an artefact -- as 'synthetic phenomenality'. But there is another way in which artificial agents (be they simulated or real) may play a crucial role in understanding or creating consciousness: (...) 'synthetic phenomenology'. Explanations involving specific experiential events require a means of specifying the contents of experience; not all of them can be specified linguistically. One alternative, at least for the case of visual experience, is to use depictions that either evoke or refer to the content of the experience. Practical considerations concerning the generation and integration of such depictions argue in favour of a synthetic approach: the generation of depictions through the use of an embodied, perceiving and acting agent, either virtual or real. Synthetic phenomenology, then, is the attempt to use the states, interactions and capacities of an artificial agent for the purpose of specifying the contents of conscious experience. This paper takes the first steps toward seeing how one might use a robot to specify the non- conceptual content of the visual experience of an (hypothetical) organism that the robot models. (shrink)

Aron Gurwitsch made two main contributions to phenomenology. He showed how to import Gestalt theoretical ideas into Husserl’s framework of constitutive phenomenology. And he explored the light this move sheds on both the overall structure of experience and on particular kinds of experience, especially perceptual experiences and conscious shifts in attention. The primary focus of this paper is the overall structure of experience. I show how Gurwitsch’s Gestalt theoretically informed phenomenological investigations provide a basis for defending what I will call (...) Phenomenal Holism, the view that all the parts of a total phenomenal state metaphysically depend on it. To illustrate how the ideas developed along the way can be used in advancing work on the phenomenology of particular kinds of experience, I draw on them in defending Husserl’s view that we can be aware of abstract objects against a phenomenological objection.

What are the relations between preattentive feature-placing and states of perceptual awareness? For the purposes of this paper, states of "perceptual awareness" are confined to the simplest possible exemplars: states in which one is aware of some aspect of the appearance of something one perceives. Subjective contours are used as an example. Early visual processing seems to employ independent, high-bandwidth, preattentive feature "channels", followed by a selective process that directs selective attention. The mechanisms that yield subjective contours are found very (...) early in this processing. An experiment by Greg Davis and Jon Driver is described; it seems to show that multiple subjective figures can be coded in these preattentive, parallel stages of visual processing. I propose that some of these preattentive states might register the very same differences that, were one aware of them, would be phenomenal differences. Some arguments pro and con on this possibility are assessed. (shrink)

We assemble here in this time and place to discuss the thesis that conscious attention can provide knowledge of reference of perceptual demonstratives. I shall focus my commentary on what this claim means, and on the main argument for it found in the first five chapters of "Reference and Consciousness". The middle term of that argument is an account of what attention does: what its job or function is. There is much that is admirable in this account, and I am (...) confident that it will be the foundation, the launching-pad, for much future work on the subject. But in the end I will argue that Campbell's picture makes the mechanisms of attention too smart: smarter than they are, smarter than they could be. If we come to a more realistic appraisal of the skills and capacities of our sub-personal minions, the "knowledge of reference" which they yield will have to be taken down a notch or two. (shrink)

The problem of the richness of visual experience is that of finding principled grounds for claims about how much of the world a person actually sees at any given moment. It is argued that there are suggestive parallels between the two-component analysis of experience defended by Wilfrid Sellars, and certain recently advanced information processing accounts of visual perception. Sellars' later account of experience is examined in detail, and it is argued that there are good reasons in support of the claim (...) that the sensory nonconceptual content of experience can vary independently of conceptual awareness. It is argued that the Sellarsian analysis is not undermined by recent work on change blindness and related phenomena; a model of visual experience developed by Ronald Rensink is shown to be in essential harmony with the framework provided by Sellars, and provides a satisfactory answer to the problem of the richness of visual experience.

O'Brien & Opie believe that some mental representations are evoked by stimuli to which a person is attending, and other mental representations are evoked by stimuli to which attention was not paid. I argue that this is the classical view of consciousness; yet this is the view which they wish to challenge.

A common view of nonhuman animals is that they lack rights because they lack conscious control over themselves. Two thoughts put pressure on this view. First, we recognize the rights of radically cognitively limited humans even though they lack conscious control over themselves. So it would seem mere prejudice to deny rights to nonhuman mammals on the grounds that animals lack autonomy. Tom Regan has been the most eloquent, powerful, and resolute defender of this thought. Second, evidence is growing that (...) healthy adults exercise non-conscious control over themselves most of the time. To deny rights to animals on the grounds that they can only exercise non-conscious control over themselves while affirming the rights of humans who similarly exercise non-conscious control over themselves most of the time also seems prejudicial. Notice that whereas the first thought compares animals to neurally diverse, cognitively challenged humans the second thought compares animals to typically developing, normal humans. In this paper I argue that accumulating empirical data lend increasing support to the second thought. (shrink)

Suppose you have recently gained a disposition for recognizing a high-level kind property, like the property of being a wren. Wrens might look different to you now. According to the Phenomenal Contrast Argument, such cases of perceptual learning show that the contents of perception can include high-level kind properties such as the property of being a wren. I detail an alternative explanation for the different look of the wren: a shift in one’s attentional pattern onto other low-level properties. Philosophers have (...) alluded to this alternative before, but I provide a comprehensive account of the view, show how my account significantly differs from past claims, and offer a novel argument for the view. Finally, I show that my account puts us in a position to provide a new objection to the Phenomenal Contrast Argument. (shrink)
