This article re-examines Ned Block‘s ( 1997 , 2007 ) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block’s claim that phenomenology and accessibility have different neural substrates is highly problematic (...) in light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness. (shrink)

We discuss the rational role of highly inattentive experiences, and argue that they can provide rational support for beliefs.

This paper aims to clarify the relationship between consciousness and attention through theoretical considerations about evolution. Specifically, we will argue that the empirical findings on attention and the basic considerations concerning the evolution of the different forms of attention demonstrate that consciousness and attention must be dissociated regardless of which definition of these terms one uses. To the best of our knowledge, no extant view on the relationship between consciousness and attention has this advantage. Because (...) of this characteristic, this paper presents a principled and neutral way to settle debates concerning the relationship between consciousness and attention, without falling into disputes about the meaning of these terms. A decisive conclusion of this approach is that extreme views on the relationship between consciousness and attention must be rejected, including identity and full dissociation views. There is an overlap between the two within conscious attention, but developing a full understanding of this mechanism requires further empirical investigations. (shrink)

This book presents a comprehensive theoretical framework that explains both human consciousness and meanings through the working of attention. By arguing for a first-person approach to consciousness, this book offers a critical overview of the major theories and empirical findings on consciousness and attention, and exemplifies how one of the most difficult and fundamental conscious experiences to account for, that is, time, can be analyzed by adopting the kind of semantics developed within the presented theoretical framework: Attentional (...) Semantics. (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)

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)

This chapter argues that attention is a distinctive mode of consciousness, which plays an essential functional role in making information accessible for use in the rational control of thought and action. The main line of argument can be stated quite simply. Attention is what makes information fully accessible for use in the rational control of thought and action. But what makes information fully accessible for use in the rational control of thought and action is a distinctive mode of (...) consciousness. Therefore, attention is a distinctive mode of consciousness. In a slogan: attention is rational-access consciousness. (shrink)

Can we consciously see more items at once than can be held in visual working memory? This question has elud- ed resolution because the ultimate evidence is subjects’ reports in which phenomenal consciousness is filtered through working memory. However, a new technique makes use of the fact that unattended ‘ensemble prop- erties’ can be detected ‘for free’ without decreasing working memory capacity.

According to commonsense psychology, one is conscious of everything that one pays attention to, but one does not pay attention to all the things that one is conscious of. Recent lines of research purport to show that commonsense is mistaken on both of these points: Mack and Rock (1998) tell us that attention is necessary for consciousness, while Kentridge and Heywood (2001) claim that consciousness is not necessary for attention. If these lines of research (...) were successful they would have important implications regarding the prospects of using attention research to inform us about consciousness. The present essay shows that these lines of research are not successful, and that the commonsense picture of the relationship between attention and consciousness can be. (shrink)

The role of conscious attention in language processing has been scarcely considered, despite the wide-spread assumption that verbal utterances manage to attract and manipulate the addressee’s attention. Here I claim that this assumption is to be understood not as a figure of speech but instead in terms of attentional processes proper. This hypothesis can explain a fact that has been noticed by supporters of Relevance Theory in pragmatics: the special role played by speaker-related information in utterance interpretation. (...) I argue that representation of the speaker in working memory reliably enhances the activation of speaker-related information and, consequently, the role it plays in determining the content of interpretations.

Induced by intake of the psychedelic substances LSD, psilocybin, DMT and mescaline, psychedelic experiences have been extensively described by subjects as entailing a most unusual increase in the scope and quality of their consciousness. Accordingly, psychedelic experiences have been widely characterised as an “expansion of consciousness.” This article poses the following question, as yet unaddressed in contemporary philosophy and the tradition of phenomenology: to what exactly does “expansion of consciousness” refer as a general characterisation of psychedelic experiences, and what role (...) might attention play therein? On the basis of Aron Gurwitsch’s phenomenology of attention, the following thesis is presented: (a) “expansion of consciousness” refers to a particular restructuration of consciousness in psychedelic experiences. (b) This occurs by means of certain extreme transformations in direction, scope, mode and degree of attention. In order to explicate this thesis, the characteristic features of psychedelic experiences that pertain to expansion of consciousness and attention are first systematically identified from a survey of subject reports. Second, it is demonstrated that the few previous attempts to understand expansion of consciousness in terms of attention as a filter/reducing-valve, spotlight or zoom-lens each fail to explain how consciousness is structured in psychedelic experiences. Third, it is argued that psychedelic expansion of consciousness is a general restructuration of consciousness by means of extreme attentional transformations. In conclusion, brief consideration is given to the question of whether psychedelic expansion of consciousness can have epistemic and ethical value for life. (shrink)

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

Mind &Language, Volume 34, Issue 4, Page 423-444, September 2019.

Is attention both necessary and sufficient for consciousness? Call this central question of this treatise, “Q.” We commonly have the experience of consciously paying attention to something, but is it possible to be conscious of something you are not attending to, or to attend to something of which you are not conscious? Where might we find examples of these? This treatise is a quest to find an answer to Q in two parts. Part I reviews the (...) foundations upon which the discourse on Q is built. Different inputs to Q produce different answers. After consideration of the many ways “attention” and “consciousness” have been defined, I settle upon phenomenal consciousness and Executive Attention (defined as a suite of strategies for structuring cognition for further processing implemented by the executive of working memory) as the most interesting inputs to Q, and the ones on which Part II focuses. Attention without consciousness seems relatively easy to establish empirically, but consciousness without attention is much harder. The putative candidates all seem to have major problems, but I build a strong abductive case for the hitherto ignored case of foveal phenomenal overflow. We consciously see far more detail in our foveal fields than we can Executively Attend, although there is a serious obstacle to our ever confirming that empirically—identifying conscious content relies on Executive Attentional report. Triangulating the capacity limitations of attention, consciousness, and working memory strengthens this case for consciousness without attention, and suggests that cognition must work something like my “Witches’ Hat Model,” on which content can become conscious outside of Executive Attention or working memory. I conclude with some reflections on the implications of my arguments for the discourse on Q, and for other discourses such as the ontologies of attention and consciousness, theories of consciousness, some other cognitive concepts, and ethical considerations in humans, animals, and machines. A conclusive answer to Q continues to elude us. It may perhaps be an ultimately insoluble conundrum. But it is the very essence of humanity to seek an answer, and in so doing, to improve our understanding of our own nature: “The proper study of mankind is man.”1. (shrink)

Visual phenomenology is highly elusive. One attempt to operationalize or to measure it is to use ‘cognitive accessibility’ to track its degrees. However, if Ned Block is right about the overflow phenomenon, then this way of operationalizing visual phenomenology is bound to fail. This thesis does not directly challenge Block’s view; rather it motivates a notion of cognitive accessibility different from Block’s one, and argues that given this notion, degrees of visual phenomenology can be tracked by degrees of cognitive accessibility. (...) Block points out that in the psychology literature, ‘cognitive accessibility’ is often regarded as either all or nothing. However, the notion motivated in the thesis captures the important fact that accessibility comes in degrees (consider the visual field from fovea the periphery). Different legitimate notions of accessibility might be adopted for different purposes. The notion of accessibility motivated here is weaker than Block’s ‘identification’ (2007) but is stronger than Tye’s ‘demonstration’ (2007). The moral drawn from the discussion of Block can be applied to the debate between Dretske and Tye on the speckled-hen style examples. Dretske’s view is even stronger than Block’s, but his arguments from various figures he provides do not support his conclusion since he does not have right ideas about fixation and attention. Tye’s picture is more plausible but his notion of accessibility is so weak that he reaches the excessive conclusion that accessibility overflows phenomenology. Three ramifications might be considered in the final part of the thesis. The first is the relation between this debate and the one concerning higher-order/same-order theories of consciousness. The second is about John McDowell’s early proposal about demonstrative concepts in visual experiences. The third is the relation between the interpretation of the Sperling case proposed here and McDowell new view of experiential contents, i.e., his story about how we carve out conceptual contents out of intuitional contents without falling pray to the Myth of the Given.

In the past two decades a number of arguments have been given in favor of the possibility of phenomenal consciousness without attentional access, otherwise known as phenomenal overflow. This paper will show that the empirical data commonly cited in support of this thesis is, at best, ambiguous between two equally plausible interpretations, one of which does not posit phenomenology beyond attention. Next, after citing evidence for the feature-integration theory of attention, this paper will give an account of the (...) relationship between consciousness and attention that accounts for both the empirical data and our phenomenological intuitions without positing phenomenal consciousness beyond attention. Having undercut the motivations for accepting phenomenal overflow along with having given reasons to think that phenomenal overflow does not occur, I end with the tentative conclusion that attention is a necessary condition for phenomenal consciousness. -/- .

Because it is unclear how a nonconscious stimulus is cognitively processed, there is uncertainty concerning variables that modulate the processing. In this context recent findings of a set of neuroimaging experiments are important. These findings suggest that conscious and nonconscious stimuli activate same areas of the brain during performance of a similar task. Further, different areas are activated when a task is performed with or without awareness of processing. It appears that the neural network involved in cognitive processing depends (...) on the awareness of processing rather than awareness of perception. Since conscious and nonconscious cognitive processing use separate neural networks, each processing is modulated by different variables. Attention modulates most conscious cognitive processing and most, but not all, nonconscious processing is attention dependent. Nonconscious tasks that require attentional resources, with or without conscious awareness, are processed using the attention dependent system. Further, because attention dependent and attention independent tasks are processed by separate neural networks, the cognitive processing and modulating variables can be understood better if cognitive tasks are defined as attention dependent or attention independent, rather than conscious or nonconscious.

Recent advances in our understanding of visual perception have shown it to be a far more complex and counterintuitive process than previously believed. Several important consequences follow from this. First, the design of an effective statistical graphics system is unlikely to succeed based on intuition alone; instead, it must rely on a more sophisticated, systematic approach. The basic elements of such an approach are outlined here, along with several design principles. An overview is then given of recent advances in our (...) understanding of visual perception, including rapid perception, visual attention, and scene perception. It then is argued that the mechanisms involved can be successfully harnessed to allow data to be displayed more effectively than at present. Several directions of development are discussed, including effective use of visual attention, the display of dynamic information, and the effective use of nonattentional and nonconscious perceptual systems.

It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing (...) objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

Can one pay attention to objects without being conscious of them? Some years ago there was evidence that had been taken to show that the answer is 'yes'. That evidence was inconclusive, but there is recent work that makes the case more compellingly: it now seems that it is indeed possible to pay attention to objects of which one is not conscious. This is bad news for theories in which the connection between attention and consciousness (...) is taken to be an essential one. It is good news for theories (including mine) in which the connection between attention and agency is taken to be essential. (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)

It seems obvious that phenomenally conscious experience is something of great value, and that this value maps onto a range of important ethical issues. For example, claims about the value of life for those in a permanent vegetative state, debates about treatment and study of disorders of consciousness, controversies about end-of-life care for those with advanced dementia, and arguments about the moral status of embryos, fetuses, and non-human animals arguably turn on the moral significance of various facts about consciousness. (...) However, though work has been done on the moral significance of elements of consciousness, such as pain and pleasure, little explicit attention has been devoted to the ethical significance of consciousness. In this book Joshua Shepherd presents a systematic account of the value present within conscious experience. This account emphasizes not only the nature of consciousness, but the importance of items within experience such as affect, valence, and the complex overall shape of particular valuable experiences. Shepherd also relates this account to difficult cases involving non-humans and those with disorders of consciousness, arguing that the value of consciousness influences and partially explains the degree of moral status a being possesses, without fully determining it. The upshot is a deeper understanding of both the moral importance of phenomenal consciousness and its relations to moral status. This book will be of great interest to philosophers and students of ethics, bioethics, philosophy of psychology, philosophy of mind and cognitive science. (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.

Integration information theories posit that the integration of information is necessary and/or sufficient for consciousness. In this paper, we focus on three of the most prominent information integration theories: Information Integration Theory, Global Workspace Theory, and Attended Intermediate-Level Theory. We begin by explicating each theory and key concepts they utilize. We then argue that the current evidence indicates that the integration of information is neither necessary nor sufficient for consciousness. Unlike GWT and AIR, IIT maintains that conscious experience is (...) both necessary and sufficient for consciousness. We present empirical evidence indicating that simple features are experienced in the absence of feature integration and argue that it challenges IIT’s necessity claim. In addition, we challenge IIT’s sufficiency claim by presenting evidence from hemineglect cases and amodal completion indicating that contents may be integrated and yet fail to give rise to subjective experience. Moreover, we present empirical evidence from subjects with frontal lesions who are unable to carry out simple instructions and argue that they are irreconcilable with GWT. Lastly, we argue that empirical evidence indicating that patients with visual agnosia fail to identify objects they report being conscious of present a challenge to AIR’s necessity claim. (shrink)

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius (...) on Kant’s view, solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.

Some have argued that a subject has an inner awareness of its conscious mental states by virtue of the non-introspective, reflexive awareness that any conscious state has of itself. But, what exactly is it like to have a ubiquitous and reflexive inner awareness of one’s conscious states, as distinct from one’s outer awareness of the apparent world? This essay derives a model of ubiquitous inner awareness (UIA) from Sebastian Watzl’s recent theory of attention as the activity (...) of structuring consciousness into an experiential center and periphery. I develop Watzl’s theory into an account of UIA by suggesting that a subject is acquainted with its own conscious mental states through being reflexively aware of how these states are structured by attention into a unified subjective perspective. I favorably compare this Watzl-inspired account of UIA against other contemporary analytic and classical Buddhist accounts of reflexive awareness and subjective character, which variously ground the inner awareness of conscious states on their intrinsic phenomenal quality of “for-me-ness,” their affective/hedonic valence, or a subject’s disposition to introspect them. The Watzl-inspired account also accommodates possible counter-examples to Watzl’s theory posed by states of minimal phenomenal experience such as lucid dreamless sleep and non-dual meditative awareness.

In this paper, I claim that extant empirical data do not support a radically embodied understanding of the mind but, instead, suggest (along with a variety of other results) a massively representational view. According to this massively representational view, the brain is rife with representations that possess overlapping and redundant content, and many of these represent other mental representations or derive their content from them. Moreover, many behavioral phenomena associated with attention and consciousness are best explained by the coordinated (...) activity of units with redundant content. I finish by arguing that this massively representational picture challenges the reliability of a priori theorizing about consciousness. (shrink)

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

Our visual experience of the world is one of diverse objects and events, each with particular colors, shapes, and motions. This experience is so coherent, so immediate, and so effortless that it seems to result from a single system that lets us experience everything in our field of view. But however appealing, this belief is mistaken: there are severe limits on what can be visually experienced. -/- For example, in a display for air-traffic control it is important to track all (...) moving items. For a single item, this can be done without problem. Three or four can also be tracked, although some degree of effort may be needed. As the number is increased further, accurate tracking becomes more and more difficult—and eventually, impossible. Performance is evidently affected by a factor within the observer which enables certain kinds of perception to occur, but is limited in some way. This factor is generally referred to as attention. -/- At various times, attention has been associated with clarity of perception, intensity of perception, consciousness, selection, or the allocation of a limited “resource” enabling various operations (see Hatfield, 1998). During the past several decades, considerable progress has been achieved by focusing on the idea of selection (Broadbent, 1982). In particular, attention can be productively viewed as contingently selective processing. This can be embodied in various ways by various processes—there need not be a single quantity identified with all forms of attention, or a single site where it operates (Allport, 1993; Tsotsos, 2011). Although “paying attention” is often considered to be a unitary operation, it may simply refer to the control of one or more selective processes, ideally in a co-ordinated way. While this view has some cost in terms of conceptual simplicity, it can help make sense of a large set of phenomena. -/- This article surveys several of the major issues in our understanding of attention and how it relates to perception. It focuses on vision, since many—if not all—considerations are similar for all sensory modalities, and the level of understanding achieved in this domain is currently the most advanced. (shrink)

What turns the continuous flow of experience into perceptually distinct objects? Can our verbal descriptions unambiguously capture what it is like to see, hear, or feel? How might we reason about the testimony that perception alone discloses? Christian Coseru proposes a rigorous and highly original way to answer these questions by developing a framework for understanding perception as a mode of apprehension that is intentionally constituted, pragmatically oriented, and causally effective. By engaging with recent discussions in phenomenology and analytic philosophy (...) of mind, but also by drawing on the work of Husserl and Merleau-Ponty, Coseru offers a sustained argument that Buddhist philosophers, in particular those who follow the tradition of inquiry initiated by Dign?ga and Dharmak?rti, have much to offer when it comes to explaining why epistemological disputes about the evidential role of perceptual experience cannot satisfactorily be resolved without taking into account the structure of our cognitive awareness. -/- Perceiving Reality examines the function of perception and its relation to attention, language, and discursive thought, and provides new ways of conceptualizing the Buddhist defense of the reflexivity thesis of consciousness-namely, that each cognitive event is to be understood as involving a pre-reflective implicit awareness of its own occurrence. Coseru advances an innovative approach to Buddhist philosophy of mind in the form of phenomenological naturalism, and moves beyond comparative approaches to philosophy by emphasizing the continuity of concerns between Buddhist and Western philosophical accounts of the nature of perceptual content and the character of perceptual consciousness.

How should we characterize the nature of conscious occurrent thought? In the last few years, a rather unexplored topic has appeared in philosophy of mind: cognitive phenomenology or the phenomenal character of cognitive mental episodes. In this paper I firstly present the motivation for cognitive phenomenology views through phenomenal contrast cases, taken as a challenge for their opponents. Secondly, I explore the stance against cognitive phenomenology views proposed by Restrictivism, classifying it in two strategies, sensory restrictivism and accompanying states. (...) On the one hand, I problematize the role of attention adopted by sensory restrictivism and I present and discuss in detail an argument that defends the limitation of sensory phenomenology so as to explain the distinction between visual and cognitive mental episodes on the basis of immediate experience. On the other hand, I address accompanying states views by discussing the empirical studies of Hurlburt et al. (2006, 2008) that defend the existence of “unsymbolized thinking”. I present how they can be construed as evidence for cognitive phenomenology views and I dispel some problems that have been raised against its acceptance. I thus conclude that cognitive phenomenology views hold up well against the restrictivist positions considered. (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)

Among the cognitive processes involved in the construction of any kind of meaning, attention is fundamental in determining why, how and what we mean. Attention plays a primary role in the process of learning the meanings of words and more generally of acquiring knowledge; signification, discourse and persuasion; perceiving, representing and (re)framing reality; shaping the attitudes of the audience; conveying values and ideologies. Conversely, the meanings of words and more generally, of signs, convey the condensed instructions for the (...) attentional operations one has to perform in order to consciously experience what is expressed through and by them. Language, by addressing and guiding attention in specific ways, helps to select, amplify and support certain semantic components and concepts, and construct and communicate knowledge and values. This book is the first to present a comprehensive overview of the extant research on the relationships between attention and meaning. The contributions collected here offer an overview of the most prominent theories and models developed so far that aim to explain how attention determines meaning construction. This book will be of interest to students, researchers and teachers in the realm of linguistics, semantics, discourse studies, semiotics, psycholinguistics, computational linguistics, linguistic development, cognitive architectures of language, neuropsychology of linguistic function and social psychology.

Often when there is no attention to an object, there is no conscious perception of it either, leading some to conclude that conscious perception is an attentional phenomenon. There is a well-known perceptual phenomenon—visuo-spatial crowding, in which objects are too closely packed for attention to single out one of them. This article argues that there is a variant of crowding—what I call ‘‘identity-crowding’’—in which one can consciously see a thing despite failure of attention to it. (...) This conclusion, together with new evidence that attention to an object occurs in unconscious perception, suggests there may be a double dissociation between conscious perception of an object and attention to that object, constraining the extent to which consciousness can be constitutively attentional. The argument appeals to a comparison between the minimal resolution (or ‘‘grain’’) of object-attention and object-seeing. (shrink)

When performing a skilled action—whether something impressive like a double somersault or something mundane like reaching for a glass of water—you exercise control over your bodily movements. Specifically, you guide their course. In what does that control consist? In this dissertation, I argue that it consists in attending to what you are doing. More specifically, in attending, agents harness their perceptual and perceptuomotor states directly and practically in service of their goals and, in doing so, settle the fine-grained manner in (...) which their bodies will move—details an intention alone leaves unsettled. This requires, among other things, that we reject views on which agents’ control is identical with their practical rationality. When all goes well, agents attentionally prioritize what is motivationally relevant to them to the exclusion of what would otherwise distract them from achieving their goals. However, sometimes agents attend distractedly—i.e., without prioritizing. As the aim of attention is to avoid distraction, this entails the possibility of defective attention. Defective attention, in turn, casts light on scenarios in which agents lose control over what they are doing, as when a skilled practitioner ‘chokes under pressure’. A complaint sometimes levelled against accounts, like mine, that claim to reduce agents’ control of their behaviour to that of causally efficacious mental states or events is that these accounts invariably deprive agents themselves of their rightful role in the generation of behaviour. This is the “Disappearing Agent Problem” for “reductive” or “event-causal” theories of action. I argue that, correctly understood, extant reductive theories do face a genuine Disappearing Agent Problem. However, it is a problem we solve by recognizing the role that conscious attention plays in making an action the agent’s own. Accordingly, I develop and defend an attentional account of action ownership. On this view, allocating conscious attention in service of your goals is sufficient for a kind of conscious perspective (“motivational perspective”), which, when active in controlling your behaviour, constitutes the behaviour as your own doing. As I explain, such perspective also contributes to explaining the subjective structure of your perceptual awareness of the world around you. (shrink)

Subjectivity theories of consciousness take self-reference, somehow construed, as essential to having conscious experience. These theories differ with respect to how many levels they posit and to whether self-reference is conscious or not. But all treat self-referencing as a process that transpires at the personal level, rather than at the subpersonal level, the level of mechanism. -/- Working with conceptual resources afforded by pre-existing theories of consciousness that take self-reference to be essential, several attempts have been made to (...) explain seemingly anomalous cases, especially instances of alien experience. These experiences are distinctive precisely because self-referencing is explicitly denied by the only person able to report them: those who experience them deny that certain actions, mental states, or body parts belong to self. The relevant actions, mental states, or body parts are sometimes attributed to someone or something other than self, and sometimes they are just described as not belonging to self. But all are referred away from self. -/- The cases under discussion here include somatoparaphrenia, schizophrenia, depersonalization, anarchic hand syndrome, and utilization behavior; the theories employed, Higher-Order Thought, Wide Intrinsicality, and Self-Representational. Below I argue that each of these attempts at explaining or explaining away the anomalies fails. Along the way, since each of these theories seeks at least compatibility with science, I sketch experimental approaches that could be used to adduce support for my position, or indeed for the positions of theorists with whom I disagree. -/- In a concluding section I first identify two presuppositions shared by all of the theorists considered here, and argue that both are either erroneous or misleading. Second, I call attention to divergent paths adopted when attempting to explain alienation experiences: some theorists choose to add a mental ingredient, while others prefer to subtract one. I argue that alienation from experience, action, or body parts could result from either addition or subtraction, and that the two can be incorporated within a comprehensive explanatory framework. Finally, I suggest that this comprehensive framework would require self-referencing of a sort, but self-referencing that occurs solely on the level of mechanism, or the subpersonal level. In adumbrating some features of this “subpersonal self,” I suggest that there might be one respect in which it is prior to conscious experience. (shrink)

Patient RB has a peculiar memory impairment wherein he experiences his memories in rich contextual detail, but claims to not own them. His memories do not feel as if they happened to him. In this paper, I provide an explanatory model of RB's phenomenology, the self-attentional model. I draw upon recent work in neuroscience on self-attentional processing and global workspace models of conscious recollection to show that RB has a self-attentional deficit that inhibits self-bias processes in broadcasting the contents (...) of episodic memories to the global workspace. Typically, self-related contents enjoy a higher salience level than other-related contents. Elimination of bias toward self-related contents diminishes the salience of those contents to the level of other-related contents. Because the typical high salience of self-related content is necessary for the feeling of ownership, RB lacks the feeling of ownership. I also discuss potential applications of the self-attentional model to other psychopathological cases. (shrink)

Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is called (...) masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

In this paper I want to introduce and defend what I call the "subject mode account" of collective intentionality. I propose to understand collectives from joint attention dyads over small informal groups of various types to organizations, institutions and political entities such as nation states, in terms of their self-awareness. On the subject mode account, the self-consciousness of such collectives is constitutive for their being. More precisely, their self-representation as subjects of joint theoretical and practical positions towards the world (...) – rather than as objects of such positions – makes them what they are. Members of such collectives represent each other as co-subjects of such positions and thus represent the world from the point of view of the collective. (shrink)

In this review of Eric Schwitzgebel's "Perplexities of Consciousness", we discuss the book's arguments in light of the role of attention in introspection.

Strong or Pure Intentionalism is the view that the phenomenal character of a conscious experience is exhaustively determined by its intentional content. Contrastingly, impure intentionalism holds that there are also non content-based aspects or features which contribute to phenomenal character. Conscious attention is one such feature: arguably its contribution to the phenomenal character of a given conscious experience are not exhaustively captured in terms of what that experience represents, that is in terms of properties of its (...) intentional object. This paper attempts to get clearer on the phenomenal contribution of conscious attention. In doing so it considers and sets aside two prominent impure intentionalist accounts, namely the Phenomenal Structure view of Sebastien Watzl, and the Demonstrative Awareness view of Wayne Wu. As an alternative I outline a Modification view, which draws on ideas in Husserlian phenomenology. On this view, we should think of the phenomenal contribution of conscious attention in terms of attentive modifications of what I call a ‘pre-attentive phenomenal field’. I develop this view and highlight its benefits over alternatives. (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)

Brentano's theory of consciousness has garnered a surprising amount of attention in recent philosophy of mind. Here I argue for a novel interpretation of Brentano's theory that casts it as more original than previously appreciated and yet quite plausible upon inspection. According to Brentano's theory, as interpreted here, a conscious experience of a tree is a mental state that can be simultaneously thought of, or framed, equally accurately as an awareness of a tree or an awareness of an (...) awareness of a tree.

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.

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)

The physical basis of conscious experience is revealed by direct observation and analysis of any conscious experience. Human conscious experience has an invariant structural mode of organization based on the three types of space-time intervals (light-like, time-like, space-like). Sensory input activates the autonomic nervous system, endocrine system, and ascending reticular activating system to produce the awake conscious state. The dorsal and ventral frontoparietal attention networks are activated. Dorsal and ventral cortical functional streams carry “what”, “where”, (...) and “when” information to the medial temporal lobe for the encoding, storage, and recall of conscious experience (episodic memory). Hippocampal place cells and time cells encode events in space and time within spatiotemporal contexts conveyed by entorhinal cortex grid cells and ramping cells. Theta phase precession unifies the encoding of space and time in the hippocampus so that segments of space and time are encoded in the hippocampus. Theta travelling waves ensure that the instantaneous output of the hippocampus consists of topographically-organized segments of space and time, space-time intervals. By parsing spatiotemporal contexts into quantal units of where and when events occur (spacetime intervals), hippocampal neurons bridge, and thereby organize events, in a conceptual organization of events (conscious experience). Space-time intervals are extracted from the hippocampus by a prefrontal cortex-basal ganglia-thalamic-prefrontal cortex loop for the cognitive, affective, and motivational aspects of conscious experience.
