Attention and Consciousness

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)

Judgments of visual resemblance (‘A looks like B’), unlike other judgments of resemblance, are often induced directly by visual experience. What is the nature of this experience? We argue that the visual experience that prompts a subject looking at A to judge that A looks like B is a visual experience of B. After elucidating this thesis, we defend it, using the ‘phenomenal contrast’ method. Comparing our account to competing accounts, we show that the phenomenal contrast between a visual experience (...) that induces the judgment that A looks like B, and a visual experience that does not induce this judgment, is best explained by the fact that the former visually represents B, whereas the latter does not.

ABSTRACTIssues concerning the putative perception/cognition divide are not only age-old, but also resurface in contemporary discussions in various forms. In this paper, I connect a relatively new d...

An often-overlooked characteristic of the human mind is its propensity to wander. Despite growing interest in the science of mind-wandering, most studies operationalize mind-wandering by its task-unrelated contents. But these contents may be orthogonal to the processes that determine how thoughts unfold over time, remaining stable or wandering from one topic to another. In this chapter, we emphasize the importance of incorporating such processes into current definitions of mind-wandering, and propose that mind-wandering and other forms of spontaneous thought (such as (...) dreaming and creativity) are mental states that arise and transition relatively freely due to an absence of constraints on cognition. We review existing psychological, philosophical and neuroscientific research on spontaneous thought through the lens of this framework, and call for additional research into the dynamic properties of the mind and brain.

I argue first that attention is a (maybe the) paradigmatic case of an object-directed, non-propositional intentional mental episode. In addition attention cannot be reduced to any other (propositional or non-propositional) mental episodes. Yet, second, attention is not a non-propositional mental attitude. It might appear puzzling how one could hold both of these claims. I show how to combine them, and how that combination shows how propositionality and non-propositionality can co-exist in a mental life. The crucial move is one away from (...) an atomistic, building block picture to a more holistic, structural picture. (shrink)

Recent psychological research shows that attention affects appearances. An “attended item looks bigger, faster, earlier, more saturated, stripier.” (Block 2010, p. 41). What is the significance of these findings? Ned Block has argued that they undermine representationism, roughly the view that the phenomenal character of perception is determined by its representational content. My first goal in this paper is to show that Block’s argument has the structure of a Problem of Arbitrary Phenomenal Variation and that it improves on other instances (...) of arguments of the same form along several dimensions (most prominently, these are arguments based on the possibility of spectral inversion). My second goal is to consider responses to Block’s version of the arbitrariness problem. I will show that most of them have serious drawbacks. Overall, the best view is to accept that attention may distort perception, sacrificing veridicality for usability. I end my discussion by showing how to develop that view. (shrink)

Our paper serves as an introduction to a budding field: the philosophy of mind-wandering. We begin with a philosophical critique of the standard psychological definitions of mind-wandering as task-unrelated or stimulus-independent. Although these definitions have helped bring mind-wandering research onto centre stage in psychology and cognitive neuroscience, they have substantial limitations that researchers must overcome to move forward. Specifically, the standard definitions do not account for (i) the dynamics of mind wandering, (ii) task-unrelated thought that does not qualify as mind-wandering, (...) and (iii) the ways that mind-wandering can be task-related. We then survey three philosophical accounts that improve upon the current psychological definitions. We first present our account of mind-wandering as “unguided thinking”. Next we review Thomas Metzinger’s view that mind-wandering can be defined as thought lacking meta-awareness and cognitive agency, as well as Peter Carruthers’s and Fabian Dorsch’s definitions of mind-wandering as disunified thinking. We argue that these latter views are inadequate, and we show that our definition of mind-wandering as unguided thinking is not only conceptually and phenomenologically precise but also can be operationalized in a principled way for empirical research.

In the interesting and thought-provoking article Grazziano and colleagues argue for their Attention Schema Theory (AST) of consciousness. They present AST as a unification of Global Workspace Theory (GWT), Illusionism, and the Higher-Order Thought (HOT) theory. We argue it is a mistake to equate 'subjective experience,' ad related terms, with dualism. They simply denote experience. Also, as presented, AST does not accurately capture the essence of HOT for two reasons. HOT is presented as a version of strong illusionism, which it (...) isn't, and HOT requires that one be aware of one's mental life, and postulates that his consists in a re-representation of what is occurring at at the lower-order levels. However, the authors deny that AST involves re-representing visual stimuli. We close by proposing an alternative unification: GWT and AST provide crucial accounts of how lower-order states are assembled and maintained, but higher-order theory provides the account of subjective experience.

Attention is essential to the life of the mind, a central topic in cognitive science, neuroscience, and psychology. Traditional debates in philosophy stand to benefit from greater understanding of the phenomenon, whether on the nature of the self, the foundation of knowledge, the natural basis of consciousness, or the origins of action and responsibility. This book is at the crossroads of philosophy of mind and cognitive science, offering a new theoretical stance on the concept of attention and how it intersects (...) with other functions of the mind, such as perception, consciousness, and action. It presents attention as directed by a subject, essential for perception, but not consciousness or action. By taking seriously the existence of a subject it stands against current trends in philosophy and cognitive science. This book offers an account of the subject and its role in attention that will both help motivate a subject-centered account and avoid some of the common criticisms regarding its existence. It engages with work by many philosophers, psychologists, and neuroscientists, including Block, Campbell, Dickie, Husserl, James, Koch, Mack and Rock, Merleau-Ponty, Treisman, and Wu. (shrink)

As a tactic for preventing an enquiry into attention’s relationship to consciousness from lapsing into ill-definition, this chapter treats ‘attention’ as a term defined by the role that is assigned to it in our explanations of empirically established psychological phenomena (especially those involving the modulation of reaction times). It reviews evidence showing that such modulations are associated with processing that stands in various relations to consciousness. The psychological phenomena that explain these modulations cannot be identified with the causes of consciousness. (...) Nor do they operate exclusively within the field of conscious awareness. If the explanation of these phenomena is to cast explanatory light on how and when consciousness occurs, it will need to do so in the context of some more complex explanatory theory. (shrink)

One popular theory of moral responsibility locates responsible agency in exercises of control. These control-based theories often appeal to tracing to explain responsibility in cases where some agent is intuitively responsible for bringing about some outcome despite lacking direct control over that outcome’s obtaining. Some question whether control-based theories are committed to utilizing tracing to explain responsibility in certain cases. I argue that reflecting on certain kinds of negligence shows that tracing plays an ineliminable role in any adequate control-based theory (...) of responsibility. (shrink)

It is often supposed one can draw a distinction, among the assumptions on which an inference rests, between certain background assumptions and certain more salient, or foregrounded, assumptions. Yet what may such a fore-v-background structure, or such structures, consist it? In particular, how do they relate to consciousness? According to a ‘Boring View’, such structures can be captured by specifying, for the various assumptions of the inference, whether they are phenomenally conscious, or access conscious, or else how easily available they (...) are to such consciousness. According to an ‘Interesting View’, there are fore-v-background structures over and above such classifications. The chapter gestures at reasons for thinking that an Interesting View at least merits exploration. The paper discusses some recent contributions to such a view in analytical philosophy; some remarks in Husserl on what he dubbed the horizonal dimension of acts of consciousness; and psychological work on the role of gist or schema representations in perception and memory. It is proposed that background assumptions can figure in consciousness by being as it were condensed into a consciously, though inattentively, entertained notion of their overall thematic gist, where this thematic gist gives the drift of a possible elucidation of how or why such-and-such salient grounds mean that so-and-so conclusion holds.

When characterizing the content of a subject’s perceptual experience, does their seeing an object entail that their visual experience represents it as being a certain way? If it does, are they thereby in a position to have perceptually-based thoughts about it? On one hand, representationalists are under pressure to answer these questions in the affirmative. On the other hand, it seems they cannot. This paper presents a puzzle to illustrate this tension within orthodox representationalism. We identify several interesting morals which (...) may be drawn in response, each of which teaches us something interesting and important about perceptual experience and its interface with cognition and related phenomena.

Perceptual learning is an enduring change in the perceptual system – and our resulting perceptions – due to practice or repeated exposure to a perceptual stimulus. It is involved in the acquisition of perceptual expertise: the ability to make rapid and reliable high-level categorizations of objects unavailable to novices. Attentional weighting is one process by which perceptual learning occurs. Advancing our understanding of this process is of particular importance for understanding what is learned in perceptual learning. Attentional weighting seems to (...) favour the hypothesis that what experts learn is simply to better direct their attention to elements of the stimulus relevant to making post-perceptual categorizations. Here I argue against this hypothesis. Attentional weighting is an integral component of the process that allows experts to come to represent high-level properties in perceptual experience. (shrink)

This essay defends the claim that endogenous attention is necessary for the justification of perceptual beliefs. I criticize the so-called phenomenal approach, according to which perceptual experiences provide justification in virtue of being phenomenally conscious. I specifically target Siegel and Silins’ (2014 ; 2019) version of the phenomenal approach. As against their view, I claim that perceptual justification cannot be understood without reference to the cognitive mechanisms which underlie the mobilization of reasons in support of propositional attitudes – attention being (...) instrumental to those very mechanisms. Relying on the distinction between propositional and doxastic justification, I first criticize the alleged cases of justification in the absence of attention before elaborating a two-stage argument in favor of the necessity of attention for perceptual justification. In the first stage, I contend that the functional role of endogenous attention makes it a necessary condition for doxastic justification. In the second stage, by relying on Turri’s (2010) analysis, I establish that propositional justification itself necessitates attention. (shrink)

Attention plays a role in demonstrative thought: It sets the targets. Visual experience also plays a role. I argue here that it makes visual information available for use in the voluntary control of focal attention. To do so I use both introspection and neurophysiological evidence from projections between areas of attentional control and neural correlates of consciousness. Campbell and Smithies also identify roles for experience, but they further argue that only experience can play those roles. In contrast, I argue that (...) experience is not the only way in which visual information could be accessed for the voluntary control of attention. (shrink)

The term “consciousness” is very often, though not always, interchangeable with the term “awareness,” which is more colloquial to many ears. We say things like “are you aware that ...” often. Sometimes we say “have you noticed that ... ?” to express similar thoughts, and this indicates a close connection between consciousness (awareness) and attention (noticing), which we will come back to later in this chapter. Ned Block, one of the key figures in this area, provides a useful characterization of (...) what he calls “phenomenal consciousness.” For him, phenomenal consciousness is experience. Experience covers perceptions, e.g., when we see, hear, touch, smell, and taste, we typically have experiences, such as seeing colors and smelling odors. It also covers bodily awareness, e.g., we typically have experiences of our own bodily temperature and positions of limbs. Consciousness is primarily about this experiential aspect of our mental lives. (shrink)

Russell’s theory of acquaintance construes perceptual awareness as at once constitutively independent of conceptual thought and yet a source of propositional knowledge. Wilfrid Sellars, John McDowell, and other conceptualists object that this is a ‘myth’: perception can be a source of knowledge only if conceptual capacities are already in play therein. Proponents of a relational view of experience, including John Campbell, meanwhile voice sympathy for Russell’s position on this point. This paper seeks to spell out, and defend, a claim that (...) offers the prospects for an attractive, unacknowledged element of common ground in this debate. The claim is that conceptual capacities, at least in a certain minimal sense implicit in McDowell’s recent work, must be operative in perceptual experience, if it is to rationalize judgement. The claim will be supported on the basis of two premises, each of which can be defended drawing, inter alia, on considerations stressed by Campbell. First, that experience rationalizes judgement only if it is attentive. Second, that attention qualifies as a conceptual capacity, in the noted, minimal sense. The conjunction of the two premises might be dubbed ‘attentional conceptualism’. (shrink)

El conocimiento es un bien necesario para el desarrollo de todo ser humano, deseamos comprender el funcionamiento de todo aquello que, de algún modo, nos afecta e implica. Nos es tan propio que llegamos a definir al ser del hombre como un ser preocupado y ocupado en y con el mundo, interesado por él, abierto mediante un gesto de arrojo cognoscitivo que no se da sino mediante nuestra capacidad de atenderlo, de verter nuestra vida de consciencia en él y alcanzar, (...) con ello, una pátina de consuelo frente al desasosiego que nos provoca lo desconocido, amenazante o indefinido. Ese mecanismo que pone en marcha nuestra atención, que nace precisamente para descubrir realidad, es el que aquí se pretende. Este trabajo busca conocer cómo, mediante la atención, realizamos ese trascendental engarce entre consciencia y realidad, cómo se da ese proceso de conocimiento –de descubrimiento– que permite nuestro desarrollo vital, qué lo genera, qué lo empuja, cómo se da y cuándo se considera consumado.

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.

This paper is about whether shifts in attention can alter what it is like to think. I begin by taking up the hypothesis that attention structures consciousness into a centre and a periphery, following Watzl's (2014; 2017) understanding of the distinction between the centre and periphery of the field of consciousness. Then I show that introspection leads to divided results about whether attention structures conscious thought into a centre and a periphery -- remarks by Martin (1997) and Phillips (2012) suggest (...) a negative answer, whereas remarks by Maher (1923) and Chudnoff (2013) suggest a positive answer. Lastly, I argue that there is behavioural evidence that lends weight to the 'yes' side of the introspective dispute. My argument makes use of Garavan's (1998) study of forming and maintaining two mental counts at once. (shrink)

One sceptical rejoinder to those who claim that sensory perception is cognitively penetrable is to appeal to the involvement of attention. So, while a phenomenon might initially look like one where, say, a perceiver’s beliefs are influencing her visual experience, another interpretation is that because the perceiver believes and desires as she does, she consequently shifts her spatial attention so as to change what she senses visually. But, the sceptic will urge, this is an entirely familiar phenomenon, and it hardly (...) involves some special or theoretically important cognitive effect on sensory perception. Even supposing that the sceptic is correct about cases that are accurately described in this way, the rejoinder oversimplifies the possible roles that attention may play in mediating cognition and perception. This paper aims to identify these different roles, and by emphasis on empirical research on feature-based and object-based attention. What emerges is a plausible and well- evidenced mental schema that describes attention -mediated cognitive penetration. At the very least, the burden of proof is shifted to the sceptic, as he then must show that there are no mental phenomena involving attention in the more nuanced ways described here. One additional benefit of this analysis is that it illuminates various features of attention and its relation to both cognition and phenomenal consciousness. Therefore the analysis should be of interest to a broad range of theorists of the mind, and not just those invested in the cognitive penetration debate. (shrink)

Singh's cultural evolutionary theory posits that methods of inducing shamanic altered states of consciousness differ, resulting in profoundly different cognitive states. We argue that, despite different methods of induction, altered states of consciousness share neurophysiological features and cause shared cognitive and behavioral effects. This common foundation enables further cross-cultural comparison of shamanic activities that is currently left out of Singh's theory.

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)

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.

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)

Being in a mood—such as an anxious, irritable, depressed, tranquil, or cheerful mood—tends to alter the way we react emotionally to the particular objects we encounter. But how, exactly, do moods alter the way we experience particular objects? Perceptualism, a popular approach to understanding affective experiences, holds that moods function like "colored lenses," altering the way we perceive the evaluative properties of the objects we encounter. In this essay, I offer a phenomenological analysis of the experience of being in a (...) mood that illustrates the limitations of the colored lens metaphor and demonstrates the basic inadequacy of the perceptualist account of moods. I argue that when we are in a mood, it is common to experience a kind of "emotional disconnection" in which we perceive evaluative properties that would normally elicit strong emotional reactions from us, but nonetheless we find that, in our present mood, we remain emotionally numb to these perceptions. Such experiences of "seeing but not feeling" are difficult to understand from within the perceptualist paradigm. Building on the work of Martin Heidegger, I sketch an alternative, phenomenological analysis of moods that can better account for experiences of emotional disconnection. On this alternative account, being in a mood does not merely alter the content of our perceptions but, rather, alters the way we interpret the overall significance of what we perceive, relative to a certain situational context.

In philosophical writings from Descartes’ time, the topic of attention attracted notice but not systematic treatment. In Descartes’s own writings, attention was not given the kind of extended analysis that he devoted to the theory of the senses, or the passions, or to the intellect and will. Nonetheless, phenomena of attention arose in relation to these other topics and were discussed in terms of mental operations and, where appropriate, relations to bodily organs. Although not producing a systematic account, Descartes frequently (...) noted attentional phenomena and creatively imagined intricate relations between sensory attention and brain processes. Descartes's observations of attentional phenomena show remarkable breadth, including cases of active mental control of attention and cases in which attention is drawn involuntarily to a novel event (first section). Descartes did not merely observe attentional phenomena; he also offered a framework for understanding them (second section). Part of this framework related attention to the activity of the will. Part also came from his conception of mind-body interaction. He assigned a significant functional role to brain processes in explaining mental phenomena, including aspects of attention. He sometimes moves beyond the usual notions of unidirectional activity or passivity in the process of interaction. Rather, mind and brain are mutually constraining. Mental and physiological processes form a functional unity, in which brain processes contribute to the mental functioning of attention (final section). Furthermore, Descartes was willing to speak of “attention” in the mindless machine portrayed in his Traité de l’homme. That work describes brain states that interact with mind to explain aspects of mental attention. But we must also suppose that these same brain states constitute attention as it occurs in non-human animals, which lack a mind. According to Descartes, although attention is, in the first instance, a mental phenomenon, it can also be ascribed to non-human animals that share brain mechanisms with human beings and the behavior of which can be described as attentively directed toward selected objects in the environment.

The main thesis of this paper is that two prevailing theories about cognitive penetration are too extreme, namely, the view that cognitive penetration is pervasive and the view that there is a sharp and fundamental distinction between cognition and perception, which precludes any type of cognitive penetration. These opposite views have clear merits and empirical support. To eliminate this puzzling situation, we present an alternative theoretical approach that incorporates the merits of these views into a broader and more nuanced explanatory (...) framework. A key argument we present in favor of this framework concerns the evolution of intentionality and perceptual capacities. An implication of this argument is that cases of cognitive penetration must have evolved more recently and that this is compatible with the cognitive impenetrability of early perceptual stages of processing information. A theoretical approach that explains why this should be the case is the consciousness and attention dissociation framework. The paper discusses why concepts, particularly issues concerning concept acquisition, play an important role in the interaction between perception and cognition. (shrink)

A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

What is attention? How does attention shape consciousness? In an approach that engages with foundational topics in the philosophy of mind, the theory of action, psychology, and the neurosciences this book provides a unified and comprehensive answer to both questions. Sebastian Watzl shows that attention is a central structural feature of the mind. The first half of the book provides an account of the nature of attention. Attention is prioritizing, it consists in regulating priority structures. Attention is not another element (...) of the mind, but constituted by structures that organize, integrate, and coordinate the parts of our mind. Attention thus integrates the perceptual and intellectual, the cognitive and motivational, and the epistemic and practical. The second half of the book concerns the relationship between attention and consciousness. Watzl argues that attentional structure shapes consciousness into what is central and what is peripheral. The center-periphery structure of consciousness cannot be reduced to the structure of how the world appears to the subject. What it is like for us thus goes beyond the way the world appears to us. On this basis, a new view of consciousness is offered. In each conscious experience we actively take a stance on the world we appear to encounter. It is in this sense that our conscious experience is our subjective perspective. (shrink)

According to the influential thesis of attentional transparency, in having or reflecting on an ordinary visual experience, we can attend only outwards, to qualities the experience represents, never to intrinsic qualities of the experience itself, i.e., to “mental paint.” According to the competing view, attentional semitransparency, although we usually attend outwards, to qualities the experience represents, we can also attend inwards, to mental paint. So far, philosophers have debated this topic in strictly armchair means, especially phenomenological reflection. My aim in (...) this paper is to show how to design an experiment, using the change detection paradigm for studying visual working memory that, if yielding positive results, would support AS. The structure of the argument is as follows. In standard change detection tasks, which involve attention to qualities the experience represents, there exists a known object integration effect (Luck and Vogel in Nature 390(6657):279–281, 1997). I formulate a hypothesis I call “the turn-off hypothesis,” according to which this effect does not exist in change detection tasks where subjects are instructed to attend to mental paint. I argue that, given AS, we have some reason to expect the turn-off hypothesis to be true, but given AT, we do not. Consequently, the truth of the turn-off hypothesis would support AS. I further argue that one can straightforwardly test the turn-off hypothesis, taking the standard change detection paradigm and instructing participants to attend inwards. (shrink)

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. 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.

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)

Artificial Intelligence is at a turning point, with a substantial increase in projects aiming to implement sophisticated forms of human intelligence in machines. This research attempts to model specific forms of intelligence through brute-force search heuristics and also reproduce features of human perception and cognition, including emotions. Such goals have implications for artificial consciousness, with some arguing that it will be achievable once we overcome short-term engineering challenges. We believe, however, that phenomenal consciousness cannot be implemented in machines. This becomes (...) clear when considering emotions and examining the dissociation between consciousness and attention in humans. While we may be able to program ethical behavior based on rules and machine learning, we will never be able to reproduce emotions or empathy by programming such control systems—these will be merely simulations. Arguments in favor of this claim include considerations about evolution, the neuropsychological aspects of emotions, and the dissociation between attention and consciousness found in humans. Ultimately, we are far from achieving artificial consciousness. (shrink)

How can we explain our capacity to think about particulars in our external environment? Many philosophers have answered this question in terms of a sophisticated conception of space and time and the movement of objects therein. A more recent reaction against this view sought to explain this capacity solely in terms of perceptual mechanisms of object individuation. Neither explanation remains fully satisfactory. This book argues for a more desirable middle ground in terms of a pragmatist approach to demonstrative thought, where (...) this capacity is explained through graded practical knowledge of objects. This view allows us to do justice to important insights put forward by both positions criticized in the book, while avoiding their potential shortcomings. It also paves the way to a more pragmatist approach to the theory of mental representation, where the notion of practical knowledge is allowed to play a central role in our cognitive life. Finally, it shows how practical knowledge may be firmly rooted in neurobiological processes and mechanisms that conform to what the empirical sciences tell us about the mind. (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)

How does attention contribute to perceptual experience? Within cognitive science, attention is known to contribute to the organization of sensory features into perceptual objects, or “object-based organization.” The current paper tackles a different type of organization and thus suggests a different role for attention in conscious perception. Within every perceptual experience we find that more subjectively interesting percepts stand out in the foreground, whereas less subjectively interesting percepts are relegated to the background. The sight of a sycamore often gains the (...) visual foreground for a nature lover, whereas the sound of a violin often gains the auditory foreground for a music lover, but not necessarily vice versa. How does the perceptual system organize early sensory processing according to the subject’s interests? The current paper reveals how this subject-based organization is brought about and maintained through top-down attention. In fact, the current paper argues that top-down attention is necessary for conscious perception in so far as it is necessary for bringing about and maintaining the subject-based organization of perceptual experience.

This paper explores whether consciousness can exist without attention. This is a hot topic in philosophy of mind and cognitive science due to the popularity of theories that hold attention to be necessary for consciousness. The discovery of a form of consciousness that exists without the influence of attention would require a change in the way that many global workspace theorists, for example, understand the role and function of consciousness. Against this understanding, at least three forms of consciousness have been (...) argued to exist without attention: perceptual gist, imagistic consciousness, and phenomenal consciousness. After first arguing that the evidence is inconclusive on the question of whether these forms of consciousness exist without attention, I here present a fourth form of consciousness that is likely to be more successful: conscious entrainment. I argue that conscious entrainment is a form of consciousness associated with skilled behavior in which attention is sometimes absent. (shrink)

In this paper I argue that the prioritization of sensory input by top-down attention is constitutive of and essential to conscious perception. Specifically, I argue that top-down attention is required to provide informational integration at the level of the subject, which can be contrasted with integration at the level of features and objects. Since the informational content of conscious perception requires integration at the level of the subject, top-down attention is necessary for conscious perception as we know it. I present (...) this argument through a theory, which I call the “Standard Theory.” According to this theory, top-down attention brings about subject-level integration for sensory input by prioritizing that input with respect to a subject-level standard.

In this book, Carlos Montemayor and Harry Haladjian consider the relationship between consciousness and attention. The cognitive mechanism of attention has often been compared to consciousness, because attention and consciousness appear to share similar qualities. But, Montemayor and Haladjian point out, attention is defined functionally, whereas consciousness is generally defined in terms of its phenomenal character without a clear functional purpose. They offer new insights and proposals about how best to understand and study the relationship between consciousness and attention by (...) examining their functional aspects. The book's ultimate conclusion is that consciousness and attention are largely dissociated. -/- Undertaking a rigorous analysis of current empirical and theoretical work on attention and consciousness, Montemayor and Haladjian propose a spectrum of dissociation—a framework that identifies the levels of dissociation between consciousness and attention—ranging from identity to full dissociation. They argue that conscious attention, the focusing of attention on the contents of awareness, is constituted by overlapping but distinct processes of consciousness and attention. Conscious attention, they claim, evolved after the basic forms of attention, increasing access to the richest kinds of cognitive contents. -/- Montemayor and Haladjian's goal is to help unify the study of consciousness and attention across the disciplines. A focused examination of conscious attention will, they believe, enable theoretical progress that will further our understanding of the human mind. (shrink)

The aim of this paper is to give a new account of the way we exercise our attention in some paradigmatic cases of aesthetic experience. I treat aesthetic experience as a specific kind of experience and like in the case of other kinds of experiences, attention plays an important role in determining its phenomenal character. I argue that an important feature of at least some of our aesthetic experiences is that we exercise our attention in a specific, distributed, manner: our (...) attention is focused on one perceptual object, but it is distributed among the various properties of this object. I argue that this way of exercising one’s attention is very different from the way we attend most of the time and it fits very well with some important features of paradigmatic examples of aesthetic experience.

One of the most influential ideas of twentieth-century art history and aesthetics is that vision has a history and it is the task of art history to trace how vision has changed. This claim has recently been attacked for both empirical and conceptual reasons. My aim is to argue for a new version of the history of vision claim: if visual attention has a history, then vision also has a history. And we have some reason to think that at least (...) in certain contexts, visual attention does have a history. (shrink)

Introspective subjective reports cannot provide direct evidence that phenomenal experience overflows cognitive access. This problem for the overflow view is underappreciated in several ways: first, it places the onus on the overflow theorist to explain how sub-jective reports can be used to provide evidence for overflow. Second, it implies that there must be a true non-overflow account of subjective reports of overflow, even if there is overflow. Thus, attempting to dis-prove all anti- overflow explanations of subjective reports is futile. Third, (...) it follows that the focus of enquiry should be on unconscious processing and indirect measures of conscious awareness; this is the area where the debate may be advanced. Finally, employment of inadmissible subjective reports continues to undermine work by over-flow theorists like Bronfman et al. and Block. (shrink)
