The Conscious Brain brings neuroscientific evidence to bear on enduring philosophical questions. Major philosophical and scientific theories of consciousness are surveyed, challenged, and extended.

This paper argues for the normative significance of attention. Attention plays an important role when describing an individual’s mind and agency, and in explaining many central facts about that individual. In addition, many in the public want answers and guidance with regard to normative questions about attention. Given that attention is both descriptively central and the public cares about normative guidance with regard to it, attention should be central also in normative philosophy. We need an (...) ethics of attention: a field of study of which normative pressures, if any, govern attention. Like the ethics of belief, the ethics of attention will connect those normative questions to issues regarding the nature of attention, i.e. to what is subject to such normative pressures. Philosophers should develop an ethics of attention that helps to provide normative guidance and that is commensurate in its richness to the descriptive significance of attention. The second half of the paper sketches a framework that may help us to get started at developing the ethics of attention. (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)

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 the popular and academic literature on the problems of the so-called attention economy, the cost of attention grabbing, sustaining, and immersing digital medias has been addressed as if it touched all people equally. In this paper I ask whether everyone has the same resources to respond to the recent changes in their stimulus environments caused by the attention economy. I argue that there are not only differences but disparities between people in their responses to the recent, (...) significant increase in the degree and persuasiveness of digital distraction. I point toward individual variance in an agent’s top-down and bottom-up attention regulation, and to further inequality-exacerbating variance in active participation on the internet and in regulating reward-seeking behaviors on the internet. Individual differences in these areas amount to disparities because they have been found to be connected to socioeconomic background factors. I argue that disparities in responding to digital distraction threaten fair equality of opportunity when it comes to digital distraction in the classroom and that they may lead to an unequal contribution of achievements that require complex cognition by people from lower socioeconomic backgrounds.

Although mind-wandering occupies up to half of our waking thoughts, it is seldom discussed in philosophy. My paper brings these neglected thoughts into focus. I propose that mind-wandering is unguided attention. Guidance in my sense concerns how attention is monitored and regulated as it unfolds over time. Roughly speaking, someone’s attention is guided if she would feel pulled back, were she distracted from her current focus. Because our wandering thoughts drift unchecked from topic to topic, they are (...) unguided. One motivation for my theory is what I call the “Puzzle of the Purposeful Wanderer”. On the one hand, mind-wandering seems essentially purposeless; almost by definition, it contrasts with goal-directed cognition. On the other hand, empirical evidence suggests that our minds frequently wander to our goals. My solution to the puzzle is this: mind-wandering is purposeless in one way—it is unguided—but purposeful in another—it is frequently caused, and thus motivated, by our goals. Another motivation for my theory is to distinguish mind-wandering from two antithetical forms of cognition: absorption and rumination. Surprisingly, previous theories cannot capture these distinctions. I can: on my view, absorption and rumination are guided, whereas mind-wandering is not. My paper has four parts. Section 1 spells out the puzzle. Sections 2 and 3 explicate two extant views of mind-wandering—the first held by most cognitive scientists, the second by Thomas Metzinger. Section 4 uses the limitations of these theories to motivate my own: mind-wandering is unguided attention. (shrink)

This book is a succinct introduction to the orienting of attention.

I argue that a study of the Nicomachean Ethics and of the Parva Naturalia shows that Aristotle had a notion of attention. This notion captures the common aspects of apparently different phenomena like perceiving something vividly, being distracted by a loud sound or by a musical piece, focusing on a geometrical problem. For Aristotle, these phenomena involve a specific selectivity that is the outcome of the competition between different cognitive stimuli. This selectivity is attention. I argue that Aristotle (...) studied the common aspects of the physiological processes at the basis of attention and its connection with pleasure. His notion can explain perceptual attention and intellectual attention as voluntary or involuntary phenomena. In addition, it sheds light on how attention and enjoyment can enhance our cognitive activities. (shrink)

I argue that when perception plays a guiding role in intentional bodily action, it is a necessary part of that action. The argument begins with a challenge that necessarily arises for embodied agents, what I call the Many-Many Problem. The Problem is named after its most common case where agents face too many perceptual inputs and too many possible behavioral outputs. Action requires a solution to the Many-Many Problem by selection of a specific linkage between input and output. In bodily (...) action the agent perceptually selects, and in this way perceptually attends to, relevant information so as to guide the execution of specific movements. Since perceptual attention is a necessary part of solving the Many-Many Problem, it is a necessary part of bodily action. Indeed, the process of implementing a solution to the Many-Many Problem, as constrained by the agent's motivational state, just is the agent's performing an intentional bodily action in the relevant way.

The perceptual model of emotions maintains that emotions involve, or are at least analogous to, perceptions of value. On this account, emotions purport to tell us about the evaluative realm, in much the same way that sensory perceptions inform us about the sensible world. An important development of this position, prominent in recent work by Peter Goldie amongst others, concerns the essential role that virtuous habits of attention play in enabling us to gain perceptual and evaluative knowledge. I think (...) that there are good reasons to be sceptical about this picture of virtue. In this essay I set out these reasons, and explain the consequences this scepticism has for our understanding of the relation between virtue, emotion, and attention. In particular, I argue that our primary capacity for recognizing value is in fact a non-emotional capacity. (shrink)

ABSTRACTEpisodic memory is the ability to revisit events in one's personal past, to relive them as if one travelled back in mental time. It has widely been assumed that such an ability imposes a metaphysical requirement on selves. Buddhist philosophers, however, deny the requirement and therefore seek to provide accounts of episodic memory that are metaphysically parsimonious. The idea that the memory perspective is a centred field of experience whose phenomenal constituents are simulacra of an earlier field of experience, yet (...) attended to in a way that presents them as happening again, is, I suggest, a better one than that the memory perspective consists in taking as object-aspect the subject-aspect of the earlier experience, or the idea that it consists in labelling a representation of the earlier experience with an I-tag.

This dissertation investigates the nature, the phenomenal character and the philosophical significance of attention. According to its central thesis, attention is the ongoing mental activity of structuring the stream of consciousness or phenomenal field. The dissertation connects the scientific study of attention in psychology and the neurosciences with central discussions in the philosophy of mind. Once we get clear on the nature and the phenomenal character of attention, we can make progress toward understanding foundational issues concerning (...) the nature and the structure of conscious mentality itself. We understand better how consciousness is connected to self-awareness and to agency, and we get a better grip on the nature of perceptual experience, the unity of consciousness, and its subjective character. The dissertation also aims at showing that the current empirical investigation of attention should be complemented with work at the level of generality that a philosophical analysis can provide; it shows how such an analysis is relevant for the scientific study of attention by providing a new conceptual framework and suggesting several new areas of research.

Grief seems difficult to locate within familiar emotion taxonomies, as it not a basic emotion nor a hybrid thereof. Here I propose that grief is better conceptualized as an emotionally rich attentional phenomenon rather than an emotion or sequence of emotions. In grieving, that another person has died, the loss incurred by the grieving, etc., occupy the forefront of the grieving subject’s consciousness while other candidate facts for their attention recede into the background. The former set of facts thus (...) sist near the top of their mental “priority structures” throughout a grief event. The hypothesis that grief is attentional helps to explain several common phenomenological features of grief experience, underpins a credible ‘metaphysics’ of grief, accounts for the extent to which grief is susceptible to choice and agency, and addresses a recent puzzle regarding our reasons to grieve and our apparent proclivity toward ‘resilience’ in the face of grief.

Important empirically informed proposals of virtue cultivation invoke techniques of goal pursuit. This paper argues that these techniques are effective in changing behavior due to the attention narrowing they bring about, and further show that such attention narrowing can threaten the appropriate exercise of phronetic-related capacities. When these phronetic-related capacities are threatened, two derivative problems arise: (1) One can end up acting in morally inappropriate ways, and (2) Even in cases where one performs the morally appropriate action, one (...) nonetheless can fail to notice and appreciate features of moral value. In light of these concerns, such techniques of goal pursuit – at least, by themselves – serve the most good for those who are merely trying to avoid vice, rather than cultivate virtue. And so, I suggest that such accounts of virtue cultivation are incomplete. I then go on to argue that these undesirable effects of attention narrowing brought about by these goal pursuit techniques may be ameliorated by also engaging in certain indirect modifications of cognition, particularly those which broaden attention. The suggestion, then, is that attention narrowing techniques of goal pursuit, along with attention broadening modifications, might best facilitate virtue cultivation when employed together. While the particulars of how we might best go about this are currently unclear, this paper ends by looking at empirical research on Open Monitoring Meditation as providing a hopeful option that might be further investigated.

Is it wrong to distract? Is it wrong to direct others’ attention in ways they otherwise would not choose? If so, what are the grounds of this wrong – and, in expounding them, do we have to at once condemn large chunks of contemporary digital commerce (also known as the attention economy)? In what follows, I attempt to cast light on these questions. Specifically, I argue – following the pioneering work of Jasper Tran and Anuj Puri – that (...) there is a right to attention, and that its existence underlies some of our claims regarding the wrongness of distractions. However, I depart from both these authors in two respects: first, I present a new way of deriving the right to attention, grounding it in the more fundamental right to mental integrity. Second, I remain agnostic on whether the contemporary business practices of capturing attention in exchange for a variety of digital products and services are plagued by routine violations of the right.

Objectives: The present study examined relationships among gaze behaviour and cardiac vagal tone using a novel stress-inducing task.Methods: Participants’ eye movements and heart rate variability were measured during an unsolvable computer-based task randomly presenting feedback of “Right” and “Wrong” answers distinctly onscreen after each trial. Subgroups were created on the basis of more frequent eye movements to the right or wrong areas onscreen.Results: Correct-Attenders maintained HRV from baseline to the stress task. In contrast, Incorrect-Attenders spent significantly more time viewing “Wrong” (...) feedback, exhibited a reduction in HRV during the stress condition, and were more likely to negatively self-evaluate performance.Conclusions: Results demonstrate that pervasive attention to negative feedback elicits perseverative stress and negative self-evaluations among university students. This study highlights the potential for studying attentional biases and emotional distress through combined measures of gaze behaviour and cardiac vagal tone. (shrink)

We investigated the impact of attention during encoding on later retrieval. During study, participants read some words aloud and named the print color of other words aloud . Then one of two memory tests was administered. The explicit test—recognition—required conscious recollection of whether a word was studied. Previously read words were recognized more accurately than were previously color named words. This contrasted sharply with performance on the implicit test—repetition priming in lexical decision. Here, words that were color named during (...) study showed priming equivalent to words that were read during study; both were responded to faster than unstudied words. Thus, an attentional manipulation during study had a strong effect on an explicit test of memory, but almost no effect on an implicit test. Focal attention during study is crucial for remembering consciously but not necessarily for remembering without awareness. (shrink)

Attention has a role in much of perception, thought, and action. On the erotetic theory, the functional role of attention is a matter of the relationship between questions and what counts as answers to those questions. Questions encode the completion conditions of tasks for cognitive control purposes, and degrees of attention are degrees of sensitivity to the occurrence of answers. Questions and answers are representational contents given precise characterizations using tools from formal semantics, though attention does (...) not depend on language. The erotetic theory proposes an integrated account of attention in cognitive control and of attentional focus in perception. The functional role of attentional focus on objects, properties, and locations has to do with picking out something that corresponds to what a task is ‘about’. The erotetic theory of attention opens new avenues in theorizing about the relationship between attention, representational content, phenomenal character, and practical reason. A novel representationalist account of salience is proposed. The theory also provides an account of distraction that suggests when distraction is a defect in practical reasoning. (shrink)

What precisely does a distraction threaten? An agent who spends an inordinate amount of time attending to her smartphone – what precisely is she lacking? I argue that whereas agency of attention is the agent’s non-automatic decision-making on what she currently pays attention to, autonomy of attention is the agent, through her second-order desires, effectively interfering with her non-automatic decision-making on what she currently pays attention to. Freedom of attention is the agent’s possibility to hold (...) or switch her focus of attention without fixating on any specific focus against her will or without distraction from chosen foci. This conceptual work provides resources to track manipulations that diminish a person’s freedom of attention. (shrink)

Previous findings in cultural psychology indicated that East Asians are more likely than North Americans to be attentive to contextual information (e.g., Nisbett & Masuda, ). However, to what extent and in which conditions culture influences patterns of attention has not been fully examined. As a result, universal patterns of attention may be obscured, and culturally unique patterns may be wrongly assumed to be constant across situations. By carrying out two cross-cultural studies, we demonstrated that (a) both European (...) Canadians and Japanese attended to moving objects similarly when the task was to simply observe the visual information; however, (b) there were cultural variations in patterns of attention when participants actively engaged in the task by constructing narratives of their observation (narrative construction). These findings suggest that cultural effects are most pronounced in narrative construction conditions, where the need to act in accordance with a culturally shared meaning system is elicited.

: Research done in recent years shows that Virtual Reality can be an effective tool for distracting attention from pain. The purpose of this study was to test how the complexity of Virtual Environment influences the experienced intensity of thermal pain stimuli. A within-subjects design experiment was conducted, using cold pressor test for pain stimulation. Research was done on 31 students of Wroclaw Universities. Participants played games created for the purpose of the study, using head mounted displays and movement (...) sensors. Two Virtual Environments differing in the level of complexity and non-VR control condition were used. The order of all conditions was counterbalanced. Participants reported significantly lower pain intensity after playing the high complexity game, compared to the low complexity game. There were also significant differences between non-VR control condition and high complexity game, but not between non-VR and low complexity game. The pain tolerance was significantly higher in both VR conditions comparing to non-VR conditions. However, no significant differences between VE’s were found in pain tolerance ratings. Results of this study provide preliminary evidence that game complexity can be related to pain experience during VR interventions. (shrink)

This paper reconciles an inconsistency between the benefits of mind wandering and a prominent conception of attention in philosophy and cognitive psychology, namely, the prioritization view. Since we prioritize the information in a task less if we are doing it while mind wandering compared to solely concentrating on it, why does our performance in the task sometimes improve when we are mind wandering? To explain this, we offer a conception of diffuse attention that generalizes from external to internal (...) forms of attention and captures deep commonalities between the two (Chun et al. 2011). We conceptualize mind wandering as an instance of internal diffuse attention that also induces diffuse attention in other concurrent tasks. Moreover, pace the prioritization view, certain tasks are in fact better performed with diffuse attention, which prioritizes information less than focused attention. Our account of mind wandering as an instance of the more general category of diffuse attention improves upon current leading philosophical views of mind wandering (such as Irving 2016) by better explaining the interaction between mind wandering and other tasks.

Attention has a long history in philosophy, despite its near absence in the twentieth century. This chapter provides an overview of philosophical research on attention. It begins by explaining the concept of "selection from limitation," contrasting it with the more recent "selection for action." It reviews historical texts that discuss attention, focusing on those in the Western canon whose understanding of "attention" aligns with contemporary usage. It then describes the differential treatment of attention in phenomenology (...) and behaviorism in the last century. Finally, it discusses contemporary research by topic: attention, perception, and knowledge; attention and consciousness; attention and action; and attention and the self. It includes work by Allport,Aristotle, Astell, Augustine, Bergson, Berkeley, Block, Bradley, Buddhaghosa, Campbell, Cherry, De Brigard, Dehaene and Naccache, Descartes, Dickie, Du Bois, Ganeri, Hegel, Heidegger, James, Kant, Koch and Tsuchiya, LaBerge, Locke, Mack and Rock, Malebranche, Merleau-Ponty, Mole, Montemayor and Haladjian, Neumann, Pashler, Posner, Prinz, Reid, Rensink, Reynolds and Heeger, Treisman, Watzl, Wittgenstein, Wollstonecraft, and Wu.

Children sometimes lose themselves in make-believe games. Actors sometimes lose themselves in their roles. Readers sometimes lose themselves in their books.

What explains the difference? My answer: attention. -/- [Unpublishable 2007-2017. This paper was referenced in Liao and Doggett (2014).].

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

Joint attention to an external object at the end of the first year is typically believed to herald the infant's discovery of other people's attention. I will argue that mutual attention in the first months of life already involves an awareness of the directednesss of attention. The self is experienced as the first object of this directedness followed by gradually more distal 'objects'. this view explains early infant affective self-consciousness within mutual attention as emotionally meaningful, (...) rather than as bearing only a spurious similarity to that in the second and third years of life. Such engagements precede and must inform, rather than derive from, conceptual representations of self and other, and can be better described as self-other conscious affects. (shrink)

We argue that pre-cueing studies show that perception is cognitively penetrated via mental imagery. It is important to be clear about the relation between attention and mental imagery here. We do not want to question the role of attention in pre-cueing studies. After all, it is attention that is being pre-cued. The pre-cue draws attention to certain features, which via top-down connections induces mental imagery for the pre-cued properties, which, then, after stimulus-presentation, interacts with and influences (...) the online computations that process stimulus features. That is, what mediates the cognitive penetration of perceptual processing is not pre-cued attention, but cue-induced mental imagery. (shrink)

In his Problems of Philosophy, Bertrand Russell distinguished knowledge by acquaintance and knowledge of truths. This paper argues for a new interpretation of the relationship between these two species of knowledge. I argue that knowledge by acquaintance of an object neither suffices for knowledge that one is acquainted with the object, nor puts a subject in a position to know that she is acquainted with the object. These conclusions emerge from a thorough examination of the central role played by (...) class='Hi'>attention in Russell's theory of knowledge. Attention bridges the gap between knowledge by acquaintance and our capacity to form judgements about the objects of acquaintance. (shrink)

This paper develops a theory of joint attention as based on, and explicable in terms of, the exercise of a minimal kind of perceptual joint know-how. On the action-based view I shall be developing, joint forms of perception are object-involving processes constituted by perceivers’ skillfully co-ordinated motor movements in social space. Joint experience can then be understood as presenting the process to the involved perceivers and joint attention as perceivers’ focus on the object of this process. This theory (...) reconciles at least some primitivist and reductionist intuitions about joint attention. (shrink)

Clinical psychologists describe decentering as the mental operation in which a subject “moves out” of immersion in a mental state. Such decentering is philosophically puzzling. It involves that a subject attends to her mental state to distance herself from it. That is, she attends to the state to make it less determining of her processing. This paper provides a philosophical explanation of the nature of decentering. It analyses decentering as a complex mental operation composed of two sub-operations: introspection and detachment. (...) Drawing on this analysis, the paper argues that decentering involves certain dynamics of attention and attention control that pose an important challenge to a selection for action theory of attention. This challenge concerns adequately describing the workings of detachment in decentering. The paper discusses how a selection for action theory might reply, yet it argues that all the available replies involve unattractive aspects. The paper closes with broader perspectives, suggesting that decentering might also pose a puzzle for other theories of attention. (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)

Jennings and Nanay (this journal, 2016) argue against my claim that action entails attention by providing putative counterexamples to the claim that action entails a Many–Many Problem. This reply demonstrates that they have misunderstood the central notion of a pure reflex on which my argument depends. A simplified form of the argument from pure reflex to the Many–Many Problem as a necessary feature of agency is given, and putative counterexamples of action without attention are addressed. Attention is (...) present in every action. In passing, the reply discusses how we should assess intuitive claims about attention and mental processing, with emphasis on learning and the automatization of attention in its development as a skill.

Orienting biases for speech may provide a foundation for language development. Although human infants show a bias for listening to speech from birth, the relation of a speech bias to later language development has not been established. Here, we examine whether infants' attention to speech directly predicts expressive vocabulary. Infants listened to speech or non-speech in a preferential listening procedure. Results show that infants' attention to speech at 12 months significantly predicted expressive vocabulary at 18 months, while indices (...) of general development did not. No predictive relationships were found for infants' attention to non-speech, or overall attention to sounds, suggesting that the relationship between speech and expressive vocabulary was not a function of infants' general attentiveness. Potentially ancient evolutionary perceptual capacities such as biases for conspecific vocalizations may provide a foundation for proficiency in formal systems such language, much like the approximate number sense may provide a foundation for formal mathematics.

Is physical presence an essential aspect of a rich educational experience? Can forms of virtual encounter achieve engaged and sustained education? Technophiles and technophobes might agree that authentic personal engagement is educationally normative. They are more likely to disagree on how authentic engagement is best achieved. This article argues that educational thinking around digital pedagogy unhelpfully reinforces this polarising debate by failing to recognise that digitalisation is, as Stiegler has argued, pharmacological: both a poison and a cure. I suggest that (...) Biesta’s critique of learnification can be applied to online learning, but that any such application does not sufficiently acknowledge the pharmacological nature of modern technology. While Stiegler has something important to contribute on the relation between technology, attention and education, I suggest his account is rather too bound up with critical theories of technology. In the end I turn to philosophers of religion, such as Eliade and Smith to suggest different ways of conceiving the role of attention in education that does set technologies up over/against the formation of attention essential to education.

A number of authors have recently cited phenomenal effects of covert attention as a source of objection to representationalism. These authors maintain that covert attention brings about changes to phenomenology that cannot be explained by changes in representational content. This paper deals with two related issues that are central to this debate: (1) how attention interacts with representational content, and (2) how variations in the precision or determinacy of representational content should be incorporated into representationalist accounts of (...) perceptual phenomenology. I address these issues in the course of responding to several recent anti-representationalist arguments that have been advance by Ned Block. I argue that attention can increase the precision of range content and that this provides a basis for defusing both the concerns raised by Block and more general concerns related to covert attention. I conclude by situating my response with respect to analogous proposals that have been developed around the determination relation. (shrink)

A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive architecture, leveraging (...) the strengths from each to develop a more comprehensive explanation. The integration of these methodologies is used to account for changes in human performance on a sustained attention task across 88 h of total sleep deprivation. The integrated model captures changes due to time awake and circadian rhythms, and it also provides an account for underlying changes in the cognitive processes that give rise to those effects. The results show the potential for developing mechanistic accounts of how fatigue impacts cognition, and they illustrate the increased explanatory power that is possible by combining theoretical insights from multiple methodologies.

This paper develops a mechanistic account of basic mental agency by identifying similarities between two of its major exemplars: endogenous attention and imagination. Five key similarities are identified: i) that both capacities are driven by currently prioritised goals that are either person-level or apt to become person-level. ii) that both deliver their outputs to the working memory iii) that both range across all and only conceptual contents; iv) that both proceed under the guidance of norms and/or habits; and v) (...) that both directly activate rather than inhibit content. These five features are consolidated by proposing that basic mental agency is essentially the power to call for conceptual content and hold it within our working memories. (shrink)

How do we show what we know? How do the models used to interpret, build understanding and sustain relationships with the world, work? Artificial intelligence models – particularly those characterized as ‘deep’ learning models – provoke a reframing of, and renewed attention to, these basic questions. Machines designed to learn through continuous, embedded use give rise to a form of automated intersubjectivity premised on normative notions of continuity, completeness and repair that are often opaque. A turn to poetic practice (...) may revivify supple categories of human and non-human, with attentive connection across multiple worlds, discursively explaining these models even as they enfold us.

This volume proposes an interdisciplinary framework that views attention from a particular angle: as a means of accessing, that is, disclosing the world in a practical and meaningful way. Moreover, it investigates how this access is concretely mediated. The book is structured in the following two parts: 1) Attention and Access The first section is concerned with attention as such. What is attention and what does it do? A common thread between the expected contributions addresses (...) class='Hi'>attention as a directional disclosing process, opening up a possibility of access to the world. This section brings contributions from a cognitive psychology/neuroscience into dialogue with phenomenology and philosophy of mind; and links attention research to new paradigms, such as predictive coding, and 4e cognition. 2) Attention and Mediation The second section tackles the question of how this disclosing process may work. Concrete disclosing is always framed by different factors and frames the world. The contributions in this section spell out the different ways in which attention is mediated and shaped by technology, situations, sociality etc., and the ways in which attention mediates our access to the world.

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.

Attention makes things look brighter and more colorful. In light of these effects, representationalist philosophers propose that attentive experiences represent more determinate color properties than inattentive experiences. Although this claim is appealing, we argue that it does not hold for one of our best conceptualizations of content determinacy, according to which an experience has more determinate contents if it represents a narrower range of values within the relevant dimension. We argue that our current empirical evidence fails to show that (...) attention has this kind of effect on color perception. We then offer an alternative, representationalist-friendly account of the attentional effects, as changes in vividness. (shrink)

Human vision supports social perception by efficiently detecting agents and extracting rich information about their actions, goals, and intentions. Here, we explore the cognitive architecture of perceived animacy by constructing Bayesian models that integrate domain‐specific hypotheses of social agency with domain‐general cognitive constraints on sensory, memory, and attentional processing. Our model posits that perceived animacy combines a bottom–up, feature‐based, parallel search for goal‐directed movements with a top–down selection process for intent inference. The interaction of these architecturally distinct processes makes perceived (...) animacy fast, flexible, and yet cognitively efficient. In the context of chasing, in which a predator (the “wolf”) pursues a prey (the “sheep”), our model addresses the computational challenge of identifying target agents among varying numbers of distractor objects, despite a quadratic increase in the number of possible interactions as more objects appear in a scene. By comparing modeling results with human psychophysics in several studies, we show that the effectiveness and efficiency of human perceived animacy can be explained by a Bayesian ideal observer model with realistic cognitive constraints. These results provide an understanding of perceived animacy at the algorithmic level—how it is achieved by cognitive mechanisms such as attention and working memory, and how it can be integrated with higher‐level reasoning about social agency.

It has been argued that the explanation of self-control requires positing special motivational powers. Some think that we need will-power as an irreducible mental faculty; others that we need to think of the active self as a dedicated and depletable pool of psychic energy or – in today more respectable terminology – mental resources; finally, there is the idea that self-control requires postulating a deep division between reason and passion – a deliberative and an emotional motivational system. This essay argues (...) that no such special motivational powers are necessary. Yet, at the same time, self-control does powerfully illustrate the importance of a feature of the mind. What it illustrates, I argue, is the importance of the mental activity of attention in the control of all action. It is by appeal to this mental activity that we can dispense with special motivational powers. If we think of Humeanism as the view that there is fundamentally only one kind of motivational system and that all action is based in that system, then this essay contributes to a defense of Humeanism. On the other hand, the essay also shows that any model of agency in terms of only beliefs and desires, motivational and representational states, or preferences and credences is incomplete. A different conception of Humeanism as the view that every mental state is either motivational, representational, or a combination of them, is false. (shrink)

In this study, voluntary and involuntary visual attention focused on different interpretations of a bistable image, were investigated using magnetoencephalography. A Necker cube with sinusoidally modulated pixels' intensity in the front and rear faces with frequencies 6.67 Hz and 8.57 Hz, respectively, was presented to 12 healthy volunteers, who interpreted the cube as either left- or right-oriented. The tags of these frequencies and their second harmonics were identified in the average Fourier spectra of the MEG data recorded from the (...) visual cortex. In the first part of the experiment, the subjects were asked to voluntarily control their attention by interpreting the cube orientation as either being on the left or right. Accordingly, we observed the dominance of the corresponding spectral component, and voluntary attention performance was measured. In the second part of the experiment, the subjects were asked to focus their gaze on a red marker at the center of the cube image without putting forth effort in its interpretation. The alternation of the dominant spectral energies at the second harmonics of the stimulation frequencies was treated as changes in the cube orientation. Based on the results of the first experimental stage and using a wavelet analysis, we developed a method which allowed us to identify the currently perceived cube orientation. Finally, we characterized involuntary attention using the distribution of dominance times when focusing attention on one of the cube orientations, which was related to voluntary attention performance and brain noise. In particular, we confirmed our hypothesis that higher attention performance is associated with stronger brain noise. (shrink)
