A visual experience, as understood here, is a sensory event that is conscious, or like something to undergo. This chapter focuses on three issues concerning such experiences. The first issue is the so-called ‘transparency’ of experiences. The chapter distinguishes a number of different interpretations of the suggestion that visual experiences are ‘transparent’. It then discusses in what sense, if any, visual experiences are ‘transparent’, and what further conclusions one can draw from that. The second issue is (...) which properties we are presented with in visual experiences. It is widely accepted that we sometimes experience red for example. But exactly which properties do we sometimes visually experience, and which properties do we never visually experience? The third issue is which particulars, if any, we are presented with in visual experiences. Do we for example sometimes visually experience mind-independent particulars like trees? Do we sometimes visually experience mind-dependent, particular ‘sense-data’? (shrink)

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She (...) then introduces a method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

According to so-called “thin” views about the content of experience, we can only visually experience low-level features such as colour, shape, texture or motion. According to so-called “rich” views, we can also visually experience some high-level properties, such as being a pine tree or being threatening. One of the standard objections against rich views is that high-level properties can only be represented at the level of judgment. In this paper, I first challenge this objection by relying on (...) some recent studies in social vision. Secondly, I tackle a different but related issue, namely, the idea that, if the content of experience is rich, then perception is cognitively penetrable. Against this thesis, I argue that the very same criteria that help us vindicate the truly sensory nature of our rich experiences speak against their being cognitively penetrable. (shrink)

Through extensive training, experts acquire specialized knowledge and abilities. In this paper, I argue that experts also acquire specialized visual experiences. Specifically, I articulate and defend the account that experts enjoy visual experiences that represent gestalt properties through perceptual learning. I survey an array of empirical studies on face perception and perceptual expertise that support this account. I also look at studies on perceptual adaptation that some might argue present a problem for my account. I show how the (...) data are subject to an interpretation that is friendly to it. Last, I address two theoretical objections to the claim that visual experiences represent gestalt properties. (shrink)

How should we characterize the functional role of conscious visual experience? In particular, how do the conscious contents of visual experience guide, bear upon, or otherwise inform our ongoing motor activities? According to an intuitive and (I shall argue) philosophically influential conception, the links are often quite direct. The contents of conscious visual experience, according to this conception, are typically active in the control and guidance of our fine-tuned, real-time engagements with the surrounding three-dimensional (...) world. But this idea (which I shall call the Assumption of Experience-Based Control) is hostage to empirical fortune. It is a hostage, moreover, whose safety is in serious doubt. Thus Milner and Goodale (1995) argue for a deep and abiding dissociation between the contents of conscious seeing, on the one hand, and the resources used for the on-line guidance of visuo-motor action, on the other. This ‘dual visual systems’ hypothesis, which finds many echoes in various other bodies of cognitive scientific research, poses a prima facie challenge to the Assumption of Experience-Based Control. More importantly, it provides (I shall argue) fuel for an alternative and philosophically suggestive account of the functional role of conscious visual experience. (shrink)

I develop a theory of what we mean by the 'look' sentences that we use to describe our visual experiences, and on that basis develop a new adverbial theory of what it is to have a visual experience with a certain character.

The usual visual experiences possess a perspectival phenomenology as they seem to present objects from a certain perspective. Nevertheless, it is not obvious how to characterise experiential content determining such phenomenology. In particular, while there are many works investigating perspectival properties of experienced objects, a question regarding how subject is represented in visual perspectival experiences attracted less attention. In order to address this problem, I consider four popular phenomenal intuitions regarding perspectival experiences and argue that the major theories (...) of perspectival experiences do not account for all of them. Relying on these observations, I show how a theory which accommodates all these intuitions can be developed by (a) recognising that visual perspectival experiences are, in fact, multimodal visuo-bodily experiences and (b) distinguishing between egocentric and structural contents. (shrink)

This paper defends the Content View: the thesis that all visual experiences have contents.

In this paper I argue that causal relations between objects are represented in visual experience, and contrast my argument and its conclusion with Michotte's results from the 1960's.

I argue against a Disjunctive approach to visual experience. I then critique three 'common-factor' views: Qualia Theory, Intentionalism and Sense-Date Theory. The latter two are combined to form Intentional Trope Theory; and that view is defended.

The thesis that we can visually perceive causal relations is distinct from the thesis that visual experiences can represent causal relations. I defend the latter thesis about visual experience, and argue that although they are suggestive, the data provided by Albert Michotte's experiments on perceptual causality do not establish this thesis. Turning to the perception of causality, I defend the claim that we can perceive causation against the objection that its arcane features are unlikely to be represented (...) in experience. (shrink)

Blindsight is classically defined as residual visual capacity, e.g., to detect and identify visual stimuli, in the total absence of perceptual awareness following lesions to V1. However, whereas most experiments have investigated what blindsight patients can and cannot do, the literature contains several, often contradictory, remarks about remaining visual experience. This review examines closer these remarks as well as experiments that directly approach the nature of possibly spared visual experiences in blindsight.

I raise a problem for common-factor theories of experience concerning the demonstrative thoughts we form on the basis of experience. Building on an insight of Paul Snowdon 1992, I argue that in order to demonstratively refer to an item via conscious awareness of a distinct intermediary the subject must have some understanding that she is aware of a distinct intermediary. This becomes an issue for common-factor theories insofar as it is also widely accepted that the general, pre-philosophical or (...) ‘naïve’ view of experience does not accept that in normal perceptual cases one is consciously aware of non-environmental (inner, mental) features. I argue then that the standard common-factor view of experience should be committed to attributing quite widespread referential errors or failures amongst the general, nonphilosophical populace – which seems an unattractively radical commitment. After clarifying the various assumptions I am making about experience and demonstrative thoughts, I consider a number of possible responses on behalf of the common-factor theorist. I finish by arguing that my argument should apply to any common-factor theory, not just avowedly ‘indirect' theories. (shrink)

Among the exciting prospects raised by advocates of predictive processing [PP] is the offer of a systematic description of our neural activity suitable for drawing explanatory bridges to the structure of conscious experience. Yet the gulf to cross seems wide. For, as critics of PP have argued, our visual experience certainly doesn’t seem probabilistic.While Clark proposes a means to make PP compatible with the experience of a determinate world, I argue that we should not rush to (...) do so. Two notions of determinacy are conflated in the claim that perception is determinate: ‘univocality’ and ‘full detail’. The former, as Clark argues, is only to be expected in any PP agent that models its world for the purpose of acting on it. But as Husserl argued, and as perceptual psychology has borne out, we significantly overestimate the degree of detail with which we perceive a univocal world.This second form of indeterminacy is due not to the probabilistic nature of PP’s model, but rather to its hierarchical structure, with increasingly coarse-grained representations as we move further from the sensory periphery. A PP system may, or may not, deliver a univocal hypothesis at each of these levels. An action-oriented PP system would only be expected to do so only at the level needed for successful action guidance. A naïve reporter’s overestimation of the degree of determinate detail in their visual experience can thereby be accounted for with a more gradual version of the ‘refrigerator light’ effect: we experience determinate details just to the degree that they’re needed – immediately as they’re needed.

This paper discusses a counterexample to the thesis that visual experience is cognitively impenetrable. My central claim is that sometimes visual experience is influenced by the perceiver’s beliefs, rendering her experience’s representational content indeterminate. After discussing other examples of cognitive penetrability, I focus on a certain kind of visual experience— that is, an experience that occurs under radically nonstandard conditions—and show that it may have indeterminate content, particularly with respect to low-level properties (...) such as colors and shapes. I then explain how this indeterminacy depends on the perceiver’s beliefs or thoughts. Finally, I attempt to generalize the case and show how other sorts of visual experiences can also be penetrated by beliefs and, hence, be indeterminate. (shrink)

In this report, the phenomenology of two blind users of a sensory substitution device – “The vOICe” – that converts visual images to auditory signals is described. The users both report detailed visual phenomenology that developed within months of immersive use and has continued to evolve over a period of years. This visual phenomenology, although triggered through use of The vOICe, is likely to depend not only on online visualization of the auditory signal but also on the (...) users’ previous (albeit distant) experience of veridical vision (e.g. knowledge of shapes and visual perspective). Once established, the sensory substitution mapping between the auditory and visual domains is not confined to when the device is worn and, thus, may constitute an example of acquired synaesthesia.

Seeing happens effortlessly and yet is endlessly complex. Among the most fascinating aspects of visual perception is its stability and constancy. As we shift our gaze or move about the world, the light projected onto the retinas is constantly changing. Yet the surrounding objects appear stable in their properties. Psychologists have long been interested in the constancies. They have asked questions such as: How good is constancy? Is constancy a fact about how things look, or is it a product (...) of our beliefs and judgments about how things look? How can the contents of visual experience be studied experimentally? Philosophers have long been interested in characterizing visual experience and have become widely interested in the constancies more recently. As psychologists and philosophers have interacted, new questions have arisen: If experience is not as of retinal stimulation (proximal mode), but does not always exhibit constancy (or at least not in all respects), how shall we describe this intermediate state? Also, should we regard any departure from constancy as a failure of the visual system, or might it be a reasonable or adaptive response? In what circumstances is seeing highly conditioned by cognitive factors such as background assumptions, and in what circumstances not? Our volume focuses on size constancy and color constancy. It considers methodologies for studying conscious visual perception, efforts to describe visual experience in relation to constancy, what it means that constancy is not always perfect, and the conceptual resources needed for explaining visual experience.

John Campbell argues that visual attention to objects is the means by which we can refer to objects, and that this is so because conscious visual attention enables us to retrieve information about a location. It is argued here that while Campbell is right to think that we visually attend to objects, he does not give us sufficient ground for thinking that consciousness is involved, and is wrong to assign an intermediary role to location. Campbell’s view on sortals (...) is also queried, as is his espousal of the so-called Referential View of Experience. (shrink)

Alva Noë’s version of the enactive conception in _Action in Perception_ is an important contribution to the study of visual perception. First, I argue, however, that it is unclear (at best) whether, as the enactivists claim, work on change blindness supports the denial of the existence of detailed visual representations. Second, I elaborate on what Noë calls the ‘puzzle of perceptual presence’. Thirdly, I question the enactivist account of perceptual constancy. Finally, I draw attention to the tensions between (...) enactivism and two trends in cognitive neuroscience: the two-visual systems model of human vision and the theory of internal forward models of action. (shrink)

Both introspection and empirical studies suggest that visual attention can affect the phenomenology of our visual experience. However, the exact character of such effects is far from clear. My aim in this chapter is to spell out the main difficulties involved in attempting to achieve a clearer view of these effects, and to make some suggestions as to how we can make progress with this issue while avoiding tempting mistakes. I do this by discussing the question of (...) whether there is a sense in which attention to a seen object can be said to contribute to the object’s visual phenomenal salience. It is often suggested that focusing visual attention on a seen object renders the object phenomenally salient. I look at potential evidence for this suggestion, and consider what form, if any, of visual phenomenal salience it may support. (shrink)

Do perceiving subjects represent kind properties in the content of their conscious visual experience when they see and recognize instances of those natural kinds? In Part 1 of my thesis I clarify this question, in Part 2 I answer it, and in Part 3 I raise a problem for previous answers. Part 1 conceives of conscious experience in an internalist way, and the unified conscious episode does not exclude having beliefs about what one sees. Following Siegel and (...) Bayne, Part 2 formulates two arguments in support of representing kind properties in the content of experience. In Part 3, I argue that attempts to distinguish visual experiences from visual beliefs might fail to account for the interplay of sensory and cognitive elements in visual object recognition. I conclude by suggesting it has not been established that visual experiences can be distinguished from visual beliefs. (shrink)

Through an interdisciplinary examination of sixteenth-century theatre, Visual Experiences in Cinquecento Theatrical Spaces studies the performative aspects of the early modern stage, paying special attention to the overlooked complexities of audience experience. Examining the period’s philosophical and aesthetic ideas about space, place, and setting, the book shows how artists consciously moved away from traditional representations of real spaces on stage, instead providing their audiences with more imaginative and collaborative engagements that were untethered by strict definitions of naturalism. In (...) this way, the book breaks with traditional interpretations of early modern staging techniques, arguing that the goal of artists in this period was not to cater to a single privileged viewer through the creation of a naturalistically unified stage but instead to offer up a complex multimedia experience that would captivate a diverse assembly of theatre-goers.

According to the Self-Location Thesis, certain types of visual experiences have self-locating and so first-person, spatial contents. Such self-locating contents are typically specified in relational egocentric terms. So understood, visual experiences provide support for the claim that there is a kind of self-consciousness found in experiential states. This paper critically examines the Self-Location Thesis with respect to dynamic-reflexive visual experiences, which involve the movement of an object toward the location of the perceiving subject. The main aim of (...) this paper is to offer an alternative interpretation of these cases which resists attributing them self-locating content, arguing for a replacement of the de se component with a non-conceptual equivalent of the indexical ‘here’. In its final section, the paper also considers an extension of the h-replacement account to cases of visual kinesthesis. (shrink)

Adam Pautz (Pautz, Nanay (ed), Current Controversies in philosophy of perception, Routledge, New York and London, 2017, Pautz, Philosophical Issues 30:257–272, 2020 ) coined the phrase “the Laws of Appearance” for some underappreciated features of perceptual experience. Pautz suggests that the modal status of the Laws presents a puzzle: it is problematic to regard them as necessary, and also problematic to regard them as contingent. This paper presents possible counterexamples to the laws, suggesting that they are contingent as originally (...) stated (Sect. 1 ). But the laws are readily modified so as to express constitutive features of normal human visual experience, and thus understood they are metaphysically necessary (Sect. 2 ). Analogous pictorial laws govern representational painting, and these can be explained by appealing to the representational format of the medium (Sect. 3 ). This invites the question whether there might be format-based explanations of the Laws of Appearance. If so, can the contingency of the format facts be squared with the necessity of the Laws? The paper answers “Yes” to both questions (Sect. 4 ). (shrink)

Both visual experience and conscious thought represent external objects, but in visual experience these objects seem present before the mind and available for direct access in a way that they don’t in conscious thought. In this paper, I introduce a couple of challenges that this “Scene-Immediacy” of visual experience raises for traditional versions of Representationalism. I then identify a resource to which Representationalists can appeal in addressing these challenges: the low-detail fringe of visual (...) experience. I argue that low-detail contents within visual experience provide the mind with a rich access to additional high-detail information, an access that is not found in conscious thought. This access, in turn, speaks to the challenges raised by the Scene-Immediacy of visual experience. Robert Schroer is an Assistant Professor at the University of Minnesota at Duluth. (shrink)

La conception naïve de l’expérience visuelle dépeint celle-ci comme une relation directe, primitive, entre le sujet voyant et l’objet vu. Elle repose sur une opposition entre la relation visuelle et la représentation mentale de l’objet vu dans l’imagination visuelle ou la vision des images. Le but de cet article est de suggérer que l’opposition naïve entre relation et représentation présente un intérêt philosophique et scientifique parfois sous-estimé. Deux théories philosophiques de la perception sont présentées : le relationnisme reprend l’esprit de (...) la conception naïve en analysant l’expérience visuelle comme une relation non représentationnelle à l’objet vu, alors que l’intentionnalisme rejette la conception naïve comme inadéquate et considère que l’expérience visuelle est représentationnelle de part en part. Après avoir introduit une notion générale de « représentation » acceptable par les deux parties, nous examinons un ensemble de travaux issus des sciences cognitives et susceptibles d’arbitrer le débat entre relationnisme et intentionnalisme. La thèse principale défendue est que le relationnisme est compatible avec les données scientifiques à notre disposition sur les processus cognitifs liés à la vision. Le relationnisme présente également un avantage philosophique puisqu’il permet de comprendre comment les représentations mentales, y compris visuelles, peuvent être fondées sur un rapport cognitif plus direct, c’est-à-dire intrinsèquement relationnel, au monde visible.

How is it that we can visually experience complete three-dimensional objects despite being limited, in any given perceptual moment, to perceiving the sides facing us from a specific spatial perspective? To make sense of this, such visual experiences must refer to occluded or presently unseen back-sides which are not sense-perceptually given, and which cannot be sense-perceptually given while the subject is occupying the spatial perspective on the object that they currently are—I call this the horizonality of visual (...) experience. Existing accounts of these horizonal references are unsatisfactory. In providing a satisfactory account, this paper argues that the content and structure of the visual experience of complete three-dimensional objects is as follows: the object is presented as being perceptible from yet-to-be-determined alternative points of view. As part of the content of visual experience, this motivates non-propositional attitudes of anticipation. Explicating this proposal is the central positive aim of this paper. (shrink)

My purpose is to take a close look at the nature of visual content. I discuss the view that visual experiences have only existential contents, the view that visual experiences have either singular or gappy contents, and the view that visual experiences have multiple contents. I also consider a proposal about visual content inspired by Kaplan's well known theory of indexicals. I draw out some consequences of my discussion for the thesis of intentionalism with respect (...) to the phenomenal character of visual experience. (shrink)

The transparency of visual experience is a widely held and important thesis in the philosophy of perception. Critical discussion of transparency has focused on visual experiences, such as the experience of visual blur that are taken to be counter examples to transparency. Here, I consider a novel objection to transparency that does not depend on intuitions about examples. The objection is that if transparency is true then we cannot explain our ability to think about our (...) visual experiences as such. In response to this objection, I develop an account of how we are able to think about our own visual experiences as such that is compatible with transparency. (shrink)

Call the view that perceptual states can have propositional contents the ‘propositional view’ - or PV for short. Proponents of PV include John McDowell and Susanna Siegel; Anil Gupta and Charles Travis are prominent opponents. In this paper, I wish to address an argument against PV put forward by Anil Gupta. Gupta argues that the conjunction of PV with two further claims, which he calls the ‘Equivalence constraint’ and the ‘reliability constraint’, leads to skepticism. I shall argue that even if (...) we grant EC, Gupta has not given us a compelling reason for rejecting PV and that if we are faced with a choice between rejecting PV and RC, we should reject RC ahead of PV. I shall also suggest that Gupta’s account begs the question against one prominent version of PV. (shrink)

Abstract: How is it that we can visually experience complete three-dimensional objects despite being limited, in any given perceptual moment, to perceiving the sides facing us from a specific spatial perspective? To make sense of this, such visual experiences must refer to occluded or presently unseen back-sides which are not sense-perceptually given, and which cannot be sense- perceptually given while the subject is occupying the spatial perspective on the object that they currently are – I call this the (...) horizonality of visual experience. Existing accounts of these horizonal references are unsatisfactory. In providing a satisfactory account, this paper argues that the content and structure of the visual experience of complete three-dimensional objects is as follows: the object is presented as being perceptible from yet-to-be-determined alternative points of view. As part of the content of visual experience, this motivates non-propositional attitudes of anticipation. Explicating this proposal is the central positive aim of this paper. (shrink)

Philosophers and psychologists alike have argued recently that relatively abstract beliefs or cognitive categories like those regarding race can influence the perceptual experience of relatively low-level visual features like color or lightness. Some of the proposed best empirical evidence for this claim comes from a series of experiments in which White faces were consistently judged as lighter than equiluminant Black faces, even for racially ambiguous faces that were labeled ‘White’ as opposed to ‘Black’ (Levin and Banaji 2006). The (...) latter result is considered especially indicative of cognitive penetration, based on the reasoning that the relevant distortions were a function of lexical labeling, and hence the effect must have been mediated by categorization at the cognitive level. I argue that this reasoning is flawed, and that the assumptions on which it relies are questionable on both empirical and theoretical grounds. I propose an alternative, low-level explanation of the phenomena, which I argue is empirically more plausible and abductively preferable to the cognitive-penetration account. The upshot is that cognitively impenetrable perceptual systems may be psychologically more plastic and hence philosophically more significant than is nowadays commonly assumed. (shrink)
