The Nature of Attention

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.

This article presents theories of attention that attempt to derive their answer to the question of what attention is from their answers to the question of what it is for some activity to be done attentively. Such theories provide a distinctive account of the difficulties that are faced by the attempt to locate processes in the brain by which the phenomena of attention can be explained. Their account does not share the pessimism of theories suggesting that the concept of attention (...) is defective. Instead it reconstrues the explanatory relationship between attention and the processes that constitute it, in a way that is illustrated here by considering the relationship between attention and the processes that are identified by the biased competition theory. After considering some of the ways in which an adverbialist approach might be developed, the article concludes by suggesting some possible solutions to a problem concerning distraction, by which prominent adverbialist theories of attention have been dogged.

This paper first demonstrates that recognition of the diversity of ways that emotional responses modulate ongoing attention generates what I call the puzzle of emotional attention, which turns on recognising that distinct emotions (e.g., fear, happiness, disgust, admiration etc.) have different attentional profiles. The puzzle concerns why this is the case, such that a solution consists in explaining why distinct emotions have the distinct attentional profiles they do. It then provides an account of the functional roles of different emotions, as (...) tied to their evaluative themes, which explains and further elucidates the distinctive attentional profiles of different emotions, so solving the puzzle of emotional attention. Following that, it outlines how such attentional profiles are reflected in the character of emotional experience and its attentional phenomenology. The resulting picture is a more detailed account of the connections between emotion and attention than is currently on offer in the philosophical literature. (shrink)

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)

We argue that recent empirical findings and theoretical models shed new light on the nature of attention. According to the resulting amplification view, attentional phenomena can be unified at the neural level as the consequence of the amplification of certain input signals of attention-independent perceptual computations. This way of identifying the core realizer of attention evades standard criticisms often raised against sub-personal accounts of attention. Moreover, this approach also reframes our thinking about the function of attention by shifting the focus (...) from the function of selection to the function of amplification. (shrink)

This is a good time for such a substantial book on Buddhaghosa. His ideas may be more difficult to digest than those of contemporary authors, but Ganeri convincingly argues for their relevance. Together with Ganeri’s considerable interpretive and philosophical work, Buddhaghosa’s view helps to fill out a perspective that is popular in cognitive science, in which the self is replaced by systems. In this case, the self is replaced by systems of attention, a view that Ganeri calls ‘Attentionalism.’ In this (...) review I will focus on two aspects of the account that I find especially puzzling, with the hope that this leads to further elucidation, whether by Ganeri or others. Specifically, I will focus on the concepts of ekaggatā, or “placing,” and anatta, or “no-self,” as interpreted by Ganeri. (shrink)

The predictive coding (PC) theory of attention identifies attention with the optimization of the precision weighting of prediction error. Here we provide some challenges for this identification. On the one hand, the precision weighting of prediction error is too broad a phenomenon to be identified with attention because such weighting plays a central role in multimodal integration. Cases of crossmodal illusions such as the rubber hand illusion and the McGurk effect involve the differential precision weighting of prediction error, yet attention (...) does not shift as one would predict. On the other hand, the precision weighting of prediction error is too narrow a phenomenon to be identified with attention, because it cannot accommodate the full range of attentional phenomena. We review criticisms that PC cannot account for volitional attention and affect-biased attention, and we propose that it may not be able to account for feature-based and intellectual attention.

'Mindfulness' is arguably the most important concept to have transplanted from Buddhist thought to contemporary Western psychology. However, whilst mindfulness was already an ambiguous term in the original context, specified more by a set of practices than by a clear definition, its cross-cultural transmission has blurred its content even further. In this paper, I assess the recent criticism of the widespread definition of mindfulness as non-elaborative, purely receptive 'bare attention'. According to the critics of bare attention, what can be characterized (...) as purely receptive is the automatic turning of attention toward an object. But should mindfulness be a quality of consciousness that is to be established and developed by the reflexive practice of meditation, it must be something more than this automatic turning of attention. This paper shows how the definition of mindfulness as bare attention can be defended by explicating it in terms of the phenomenological model of attention. (shrink)

One of the most influential recent accounts of attention is Wayne Wu’s. According to Wu, attention is selection-for-action. I argue that this proposal faces a dilemma: either it denies clear cases of attention capture, or it acknowledges these cases but classifies many inattentive episodes as attentive.

The nature of attention has been the topic of a lively research programme in psychology for over a century. But there is widespread agreement that none of the theories on offer manage to fully capture the nature of attention. Recently, philosophers have become interested in the debate again after a prolonged period of neglect. This paper contributes to the project of explaining the nature of attention. It starts off by critically examining Christopher Mole’s prominent “adverbial” account of attention, which traces (...) the failure of extant psychological theories to their assumption that attending is a kind of process. It then defends an alternative, process-based view of the metaphysics of attention, on which attention is understood as an activity and not, as psychologists seem to implicitly assume, an accomplishment. The entrenched distinction between accomplishments and activities is shown to shed new light on the metaphysics of attention. It also provides a novel diagnosis of the empirical state of play.

This is a study in thinking according to, but not withheld by, traditional methods from the branch of philosophy called Experiential Philosophy. Philosophers are interested in the topic of thought, if no one else. Yet, thinking is what we do sixteen hours a day. Or, as this study will show, thinking is what is done to us sixteen hours a day. What is thinking? Why is it? And, who is in charge here anyway? The following book will enter these questions (...) and make a serious attempt to keep deviations from target as small as possible. The thesis of this book is based on the recognition that thought is an activity in human beings that (1) proceeds in a fragmented way and that (2) basically cannot be halted. We cannot opt out of thinking. The conclusion is that this accounts for human suffering, lack of direction, and chaos in daily actions and decisions. This leads to the further conclusion that thinking is not something we do, it is something that is being done in us. (shrink)

Is attention a cognitive process? I reconstruct and critically assess an argument first proposed by Christopher Mole that it cannot be so. Mole’s argument is influential because it creates theoretical space for a unifying analysis of attention at the subject level (though it does not entail it). Prominent philosophers working on attention such as Wayne Wu and Philipp Koralus explicitly endorse it, while Sebastian Watzl endorses a related version, this despite their differing theoretical commitments. I show that Mole’s argument is (...) invalid, amend it to secure its validity, but argue that it still fails. I consider the extent to which the failure of Mole’s argument spreads to the versions offered by Wu, Koralus and Watlz. Mole’s argument fails because it equivocates between the set of conditions that suffice for constituting attention and the subset of those conditions which are salient, but insufficient, for constituting it. Reflection on this distinction has consequences for the individuation not just of attentional processes but all cognitive processes. (shrink)

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)

Jonardon Ganeri presents a radically reoriented account of mind, to which attention is the key. It is attention, not self, that explains the experiential and normative situatedness of humans in the world. Ganeri draws together three disciplines: analytic philosophy and phenomenology, cognitive science and psychology, and Buddhist thought.

Zenon Pylyshyn argues that cognitively driven attentional effects do not amount to cognitive penetration of early vision because such effects occur either before or after early vision. Critics object that in fact such effects occur at all levels of perceptual processing. We argue that Pylyshyn’s claim is correct—but not for the reason he emphasizes. Even if his critics are correct that attentional effects are not external to early vision, these effects do not satisfy Pylyshyn’s requirements that the effects be direct (...) and exhibit semantic coherence. In addition, we distinguish our defense from those found in recent work by Raftopoulos and by Firestone and Scholl, argue that attention should not be assimilated to expectation, and discuss alternative characterizations of cognitive penetrability, advocating a kind of pluralism.

In this paper I consider Simone Weil’s notion of attention as the fundamental and necessary condition for mystical experience, and investigate Iris Murdoch’s secular adaptation of attention as a moral attitude. After exploring the concept of attention in Weil and its relation to the mystical, I turn to Murdoch to address the following question: how does Murdoch manage to maintain Weil’s idea of attention, even keeping the importance of mysticism, without Weil’s religious metaphysical background? Simone Weil returns to the importance (...) of attention throughout her writing. To attend, for Weil, means to empty oneself of all that is personal, primarily one’s will, which Weil sees as the essence of the human individual. This act imitates God’s act of creation, considered as a withdrawal in order to let something other than himself exist. Since such withdrawal represents God’s supreme act of love, salvation for human beings lies in the attempt to do likewise. By giving up one’s will, while desiring God with all of one’s soul, one creates the conditions for God to descend into the soul. This ‘passive activity’ is attention. Weil’s writings had a deep impact on Iris Murdoch’s moral philosophy. In particular, Weil’s concept of attention is carried into Murdoch’s thought almost unchanged, with one striking exception: the absence of God in Murdoch’s system. Just as surprisingly, Murdoch at the same time maintains that mysticism and spirituality are crucial for morality, nor does she wish to sever the connection between attention and mysticism. Is Murdoch being inconsistent? I believe not. But the idea of attention as a mystical concept, within a metaphysics which has no room for God, requires further examination. For Murdoch, attention is the central capacity of the morally good person. Attention is, like in Weil, connected with an emptying of the self (for Murdoch the Ego) and a renunciation of will, in order to let something external make an impression in the subject. However, in Murdoch’s philosophy such external impression is not given by God, but by reality itself. Thus far, it appears, the notion of mysticism would be unnecessary. Yet for Murdoch reality is not something that we passively perceive, but something that requires a moral faculty – attention – made up of selflessness and desire for the good, in order to be apprehended. Two elements of mysticism then begin to surface: firstly, apprehension of reality requires a faculty that is not purely intellectual, but that involves the whole of the individual, including intuitions that one may be unable to explain (which Murdoch is happy to call ‘the soul’); secondly, the reality thus apprehended is considered as transcendent, insofar as its truth, infinitely distant, transcends the individual’s complete grasp. Thus the mystic, in Murdoch’s system, is regarded as an ideal moral person, not because s/he is guided by God, but because of his/her selfless ability to attend to the world beyond oneself and intuit its moral and metaphysical truth.

Wayne Wu argues that attention is necessary for action: since action requires a solution to the ‘Many–Many Problem’, and since only attention can solve the Many–Many Problem, attention is necessary for action. We question the first of these two steps and argue that it is based on an oversimplified distinction between actions and reflexes. We argue for a more complex typology of behaviours where one important category is action that does not require a solution to the Many–Many Problem, and so (...) does not require attention. (shrink)

: We provide empirical examples to conceptually clarify some items on Firestone & Scholl’s (F&S’s) checklist, and to explain perceptual effects from an attentional and memory perspective. We also note that action and embodied cognition studies seem to be most susceptible to misattributing attentional and memory effects as perceptual, and identify four characteristics unique to action studies and possibly responsible for misattributions.

This essay argues that current theories of action fail to explain agentive control because they have left out a psychological capacity central to control: attention. This makes it impossible to give a complete account of the mental antecedents that generate action. By investigating attention, and in particular the intention-attention nexus, we can characterize the functional role of intention in an illuminating way, explicate agentive control so that we have a uniform explanation of basic cases of causal deviance in action as (...) well as other defects of agency, explain cases of skilled agency and sharpen questions about the role of thought in agency. This provides for a different orientation in the theory of action. (shrink)

This article discusses several key issues concerning the study of attention and its relation to visual perception, with an emphasis on behavioral and experiential aspects. It begins with an overview of several classical works carried out in the latter half of the 20th century, such as the development of early filter and spotlight models of attention. This is followed by a survey of subsequent research that extended or modified these results in significant ways. It covers current work on various forms (...) of induced blindness and on the capabilities of nonattentional processes. It also includes proposals about how a "just-in-time" allocation of attention can create the impression that we see our surroundings in coherent detail everywhere, as well as how the failure of such allocation can result in various perceptual deficits. The final section examines issues that have received little consideration to date, but may be important for new lines of research in the near future. These include the prospects for a better characterization of attention, the possibility of more systematic explanations, factors that may significantly modulate attentional operation, and the possibility of several kinds of visual attention and visual experience.

It is suggested that the relationship between visual attention and conscious visual experience can be simplified by distinguishing different aspects of both visual attention and visual experience. A set of principles is first proposed for any possible taxonomy of the processes involved in visual attention. A particular taxonomy is then put forward that describes five such processes, each with a distinct function and characteristic mode of operation. Based on these, three separate kinds—or possibly grades—of conscious visual experience can be distinguished, (...) each associated with a particular combination of attentional processes. (shrink)

In this thesis three independent answers to the question ‘what is attention?’ are provided. Each answer is a description of attention given through one of the perspectives that people have on the mental phenomenon. The first answer is the common-sense answer to the question, and is an account of the folk psychology of attention. The understanding of attention put forward here is of attention as a limited, divisible resource that is used in mental acts. The second answer is the empirical (...) answer to the question, and is an account of the metaphysics of attention. The understanding of attention put forward here is the account of attention proposed by Christopher Mole in his theory of attention as cognitive unison. The third answer is the experiential answer to the question, and is an account of the phenomenology of attention. The understanding of attention put forward here is of attention as a kind of directed mental effort. These three answers to the question are shown to be intimately related to each other, and to inform each other in important ways. They are also shown to be fundamentally different answers to each other with none being reducible to another, or more important than another. In the end, they will be found to be answers that arise from the differing perspectives that people are restricted to when considering the nature of mental phenomena, perspectives that must be recognised if an account of such phenomena is to be provided.

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)

I argued in Nanay 2010 that we cannot characterize perceptual content without reference to attention. Here, I defend this account from three objections raised by Jagnow 2011. This mainly takes the form of clarifying some details not sufficiently elaborated in the original article and dispelling some potential misunderstandings.

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)

I argue that perceptual content is always affected by the allocation of one’s attention. Perception attributes determinable and determinate properties to the perceived scene. Attention makes (or tries to make) our perceptual attribution of properties more determinate. Hence, a change in our attention changes the determinacy of the properties attributed to the perceived scene.

Selective access and integration underlie much of our visual experience. This article describes several of the experimental techniques used to investigate these processes, and some of the major results achieved in our understanding of their operation.

In the not-too-distant past, vision was often said to involve three levels of processing: a low level concerned with descriptions of the geometric and photometric properties of the image, a high level concerned with abstract knowledge of the physical and semantic properties of the world, and a middle level concerned with anything not handled by the other two. The negative definition of mid-level vision contained in this description reflected a rather large gap in our understanding of visual processing: How could (...) the here-and-now descriptions of the low levels combine with the enduring knowledge of the high levels to produce our perception of the surrounding world? A number of experimental and theoretical efforts have been made over the past few decades to solve this "mid-level crisis". One of the more recent of these is based on the phenomenon of change blindness—the difficulty in seeing a large change in a scene when the transients accompanying that change no longer convey information about its location (Rensink, O'Regan, & Clark, 1997; Rensink, 2000a). Phenomenologically, this effect is quite striking: the change typically is not seen for several seconds, after which it suddenly snaps into awareness. During the time the change remains "invisible", there is an apparent disconnection of the low-level descriptions (which respond to the change) from subjective visual experience (which does not). As such, this effect would seem to have the potential to help us understand how mid-level mechanisms might knit low- and high-level processes into a coherent representation of our surroundings. -/- It is argued here that this potential can indeed be realized, and that change blindness can teach us much about the nature of mid-level vision.3 A number of studies are first reviewed showing that the perception of a scene does not involve a steady buildup of detailed representation: rather, it is a dynamic process, with focused attention playing one of the main roles, viz., forming coherent object representations whenever needed. It is then argued that change blindness can also shed considerable light on the nature of focused attention itself, such as its speed, capacity, selectivity, and ability to bind together visual properties into coherent structures. (shrink)

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

A set of visual search experiments tested the proposal that focused attention is needed to detect change. Displays were arrays of rectangles, with the target being the item that continually changed its orientation or contrast polarity. Five aspects of performance were examined: linearity of response, processing time, capacity, selectivity, and memory trace. Detection of change was found to be a self-terminating process requiring a time that increased linearly with the number of items in the display. Capacity for orientation was found (...) to be about 5 items, a value comparable to estimates of attentional capacity. Observers were able to filter out both static and dynamic variations in irrelevant properties. Analysis also indicated a memory for previously-attended locations. These results support the hypothesis that the process needed to detect change is much the same as the attentional process needed to detect complex static patterns. Interestingly, the features of orientation and polarity were found to be handled in somewhat different ways. Taken together, these results not only provide evidence that focused attention is needed to see change, but also show that change detection itself can provide new insights into the nature of attentional processing.

Several studies (e.g., Becklen & Cervone, 1983; Mack & Rock, 1998; Neisser & Becklen, 1975) have found that observers attending to a particular object or event often fail to report the presence of unexpected items. This has been interpreted as inattentional blindness (IB), a failure to see unattended items (Mack & Rock, 1998). Meanwhile, other studies (e.g., Pashler, 1988; Phillips, 1974; Rensink et al., 1997; Simons, 1996) have found that observers often fail to report the presence of large changes in (...) a display when these changes occur simultaneously with a transient such as an eye movement or flash of the display. This has been interpreted as change blindness (CB), a failure to see unattended changes (Rensink et al., 1997). In both cases there is a striking failure to report an object or event that would be quite visible under other circumstances. And in both cases there is a widespread (although not universal) belief that the underlying cause has to do with the absence of attention. The question then arises as to how these effects might be related. Is CB the same thing as IB? If not, what is the relation between them? And given that these phenomena deal with failures of subjective perception, what can they teach us about the nature of our visual experience? In particular, what can they teach us about the role played by visual attention? (shrink)
