Recently, a new movement has arisen in the philosophy of perception: one that views perception as a natural kind. Strangely, this movement has neglected the extensive work in philosophy of science on natural kinds. The present paper remedies this. I start by isolating a widespread and influential assumption, which is that we can give necessary and sufficient conditions for perception. I show that this assumption is radically at odds with current philosophy of science work on natural kinds. I then develop (...) an alternative, new view of perception. This new view takes as its starting point the dominant position on kinds in the life sciences: the homeostatic property cluster account. I show that, if you accept this view, then all of the putative cases of unconscious perception are more plausibly seen as cases where it is indeterminate whether the mental episode in question is an instance of perception.

This paper examines attention as a scientific concept, and argues that it has a patchwork structure. On this view, the concept of attention takes on different meanings, depending on the scientific context. I argue that these different meanings vary systematically along four dimensions, as a result of the epistemic goals of the scientific programme in question and the constraints imposed by the scientific context. Based on this, I argue that attention is a general reasoning strategy concept: it provides general, non-specific (...) guidance that aids scientific work. As well as shedding light on attention as a scientific concept, this theory has two wider consequences. First, it demonstrates that the patchwork approach is a fruitful way to think about psychological concepts. Second, it provides novel resources to resist eliminativism about attention. (shrink)

The question of whether perception is encapsulated from cognition has been a major topic in the study of perception in the past decade. One locus of debate concerns the role of attention. Some theorists argue that attention is a vehicle for widespread violations of encapsulation; others argue that certain forms of cognitively driven attention are compatible with encapsulation, especially if attention only modulates inputs. This paper argues for an extreme thesis: no effect of attention, whether on the inputs to perception (...) or on perceptual processing itself, constitutes a violation of the encapsulation of perception.

In recent philosophical work on attention, several authors have employed versions of an argument purporting to show that attention is not identical to any cognitive process. Others have criticised this argument. The present article addresses their various criticisms, and shows the original argument to be a valid one. It also shows that this argument cannot be resisted by taking attention to be a disjunction of several processes, by taking it be a genus of process that is composed of various species, (...) nor by taking it to be a process-determinable, for which particular cognitive processes are determinates. The metaphysical position that most readily accommodates this argument’s conclusion is a version of adverbialism. It should be understood as making a claim about the essence of attention. Some of the confusions in this area are shown to originate in the difficulty of glossing such a claim in modal terms. (shrink)

How are attention and consciousness related? Can we learn what the contents of someone’s consciousness are if we know the targets of their attention? What can we learn about the contents of consciousness if we know the targets of attention? Although introspection might suggest that attention and consciousness are intimately connected, a good body of recent findings in cognitive psychology and cognitive neuroscience brings compelling reasons to believe that they are two separate and independent processes. This paper attempts to bring (...) attention and consciousness back together to make the study of attentional distributions an essential ingredient for the study of the contents of consciousness. My proposal has two main components. First, I introduce a framework for systematizing the relations between attention in its different forms and consciousness in its different forms. Although philosophers and cognitive scientists have repeatedly highlighted the importance of such systematization, most details are still to be worked out. Here I take an initial stab at this project based on the notion of degrees of informational enhancement. Second, I introduce the notion of vicarious attention to account for a kind of additional processing benefit that comes for free when attention is allocated to a target. I then propose that this kind of processing must also be considered when mapping attention targets into contents of consciousness. (shrink)

In this paper, we address reports of “selfless” experiences from the perspective of active inference and predictive processing. Our argument builds upon grounding self-modelling in active inference as action planning and precision control within deep generative models – thus establishing a link between computational mechanisms and phenomenal selfhood. We propose that “selfless” experiences can be interpreted as cases in which normally congruent processes of computational and phenomenal self-modelling diverge in an otherwise conscious system. We discuss two potential mechanisms – within (...) the Bayesian mechanics of active inference – that could lead to such a divergence by attenuating the experience of selfhood: “self-flattening” via reduction in the depth of active inference and “self-attenuation” via reduction of the expected precision of self-evidence.

The term attention has been used to mean so many different things that some have despaired of it being useful at all. This paper is devoted to bringing a modicum of order to the chaos through the time-honored device of categorization. The chief purpose of this paper is to introduce a comprehensive descriptive taxonomy of the nuanced ways the term attention may be employed. It is presented in table form, followed by elucidations and illustrations of each of its items. But (...) first, I offer reasons why a taxonomy of attention is needed and explore some of its possible benefits. After presenting the taxonomy, I sketch by way of example how it might be applied to two interesting questions: is the umbrella term attention still useful?; and, what is it that ties the subdefinitions of attention together yet distinguishes them from other kinds of cognition?

The notion of subjective vividness plays a fundamental role in comparing different conscious experiences, yet it is poorly understood and lacks proper definition. Philosophical reflection on this topic is especially scarce. This article proposes a novel account of vividness arguing that its standard operationalisation in psychology conflates two major modality‐general dimensions along which experiences vary—subjective intensity and subjective specificity—which themselves are determined by further modality‐specific factors. The article identifies the neural underpinnings of these factors in the visual domain, demonstrates the (...) unificatory power of the account, and argues that vividness is part of the content of perception.

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)

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)
