Philosophy of Perception, General

This paper deals with Peirce’s understanding of perceptual judgment, relating it to the conditions for the use of language defined by Michael Dummett. Namely, drawing on Dummett’s requirement for harmony between descriptive and evaluative aspects of our linguistic practice, we will try to give an interpretation of Peirce’s view of perception that implies rejecting the idea that the formation of a perceptual judgment has an inferential structure. On the other hand, since it is, in Peirce’s opinion, the structure of abductive (...) inference, this approach should enable us to draw some conclusions related to abduction in general. (shrink)

Representationalism (aka intentionalism) has been the most significant weapon in the late twentieth century defence of direct realism. However, although the representationalist objection to the Phenomenal Principle might provide an effective response to the arguments from illusion and hallucination, plausible representationalist theories of perception are, when fleshed-out, incompatible with metaphysical direct realism’s directness-claim. Indeed within cognitive science, direct perception is the avowedly-radical anti-representationalist heterodoxy. Drawing on both the philosophy and cognitive science, we develop a robust argument against representationalist direct realism (...) which does not rest on illusory cases or the notion of an object of immediate awareness. None of the representations so far posited, or in prospect, can supply the content required of a representation in a direct realist theory of veridical perception. (shrink)

Analytic philosophy took a wrong turn when it rehabilitated direct realism. From the perspective of cognitive science, it seems that we can have the directness-claim or the realism-claim but not both together. Up until the mid-1900s the vast majority of philosophers dismissed direct realism as hopelessly naïve, but by the close of the century it had become the orthodoxy within analytic philosophy. In contrast, mainstream cognitive science has remained constant in its opposition to the directness-claim, and when the directness-claim is (...) maintained, by an avowedly-radical minority, it is at the expense of the realism-claim.

This paper aims at offering a new disjunctivist solution – anomalous disjunctivism – to the screening-off problem. Anomalous disjunctivism focuses on the necessary causal conditions for perception and hallucination. It argues that the proximate cause is contingent on causing a particular kind of sensory experience that can either be perceptual or hallucinatory. It further shows that the perceived thing is a necessary causal condition for perceptual experience and the failure of perception is a necessary causal condition for the hallucinatory counterpart. (...) It is the case that any account of a hallucinatory experience relies on the nature of hallucination, and, therefore, the anti-naïve realist has to agree that the necessary causal condition matters. As a consequence, whatever account we take for a hallucination, it need not apply to its perceptual counterpart. The screening-off problem, thereby, is dissolved. (shrink)

There are two arguments in contemporary philosophy of consciousness and perception with which every theory of sensory awareness and phenomenal presence must deal: the Argument from Transparency and the Argument from Revelation. The first one is about the intentionality of sensations or conscious sensory states and the second one is about their epistemic role. These both arguments depend, on the one hand, on specific interpretations of ‘transparency’ and ‘revelation’ and, on the other hand, on specifying the formal structures that they (...) have. My main aim is to specify the conceptual conditions of conceivability of the explananda of a theory of phenomenal presence by analyzing transparency and revelation and their corresponding arguments. I will argue that we can arrive to neutral versions of the both arguments which do not depend on endorsing metaphysical theses about sensory content. From these versions of the arguments, I will show that to understand the relationships between them will give rise to a basic characterization of what must be explained by any theory of sensory phenomenal presence. My plan is as follows. In the first part I will present what I think to be the standard interpretations of the two arguments, their logical structures and the interpretations that I take to be the more neutral ones. Hence, I will offer an analysis of each one which allows us to identify some metaphysical and epistemological commitments of their interpretative alternatives. In the second part I will relate these arguments and I will make explicit their strongest relationships. I will present the working concepts of ‘transparent’ and ‘revealed’ and what I call the Transparency-Revelation Argument characterizing the explananda of a non-reductive theory of phenomenal presence. Such argument gives rise to three claims which will be presented as describing the basic explananda of a theory of sensory phenomenal presence. Finally, in the third section, I will sketch the main conclusions. -/- . (shrink)

ABSTRACTI defend the view that aspect-perception – seeing as a duck, or a face as courageous – typically involves concept-application. Seemingly obvious, this is contested by Avner Baz: ‘aspects ma...

Over the past 50 years, philosophers and psychologists have perennially argued for the existence of analog mental representations of one type or another. This study critically reviews a number of these arguments as they pertain to three different types of mental representation: perceptual representations, imagery representations, and numerosity representations. Along the way, careful consideration is given to the meaning of “analog” presupposed by these arguments for analog mental representation, and to open avenues for future research.

In this paper I argue that the ecological approach to perception provides resources to overcome the causal argument against disjunctivism. According to the causal argument, since the brain states that proximally cause the perceptual experience and the corresponding hallucinatory one can be of the same type, there would be no good reason to reject that the perceptual experience and the corresponding hallucinatory experience have fundamentally the same nature. Disjunctivism in respect to the nature of the experience would then be false. (...) I identify three assumptions that support the causal argument: the indistinguishability assumption, the linearity assumption and the duplication assumption. According to the ecological approach to disjunctivism, these assumptions should be rejected, opening up room for a version of disjunctivism that I call 'Ecological Disjunctivism'. Perceptual episodes are extended over time and supervenient to the organism-environment system. They can be distinguished from the 'corresponding' hallucinations because the former result from a controlled process of attunement to the environment, whereas hallucinations are passive and insensible to the exploratory activities of the perceptual system. Finally, the ecological disjunctivism, inasmuch as it is immune to the causal argument, is more advantageous in relation to the negative and positive disjunctivisms. (shrink)

What is the correct procedure for determining the contents of perception? Philosophers tackling this question increasingly rely on empirically-oriented procedures in order to reach an answer. I argue that this constitutes an improvement over the armchair methodology constitutive of phenomenal contrast cases, but that there is a crucial respect in which current empirical procedures remain limited: they are unimodal in nature, wrongly treating the senses as isolatable faculties. I thus have two aims: first, to motivate a reorientation of the admissible (...) contents debate into a multimodal framework, charting its various significances. The second is to explore whether any experimental studies of multimodal perception support a so-called Liberal (or ‘high-level’ or ‘rich’) account of perception’s admissible contents. I conclude that the McGurk effect and the ventriloquist effect are both explicable without the postulation of high-level content, but that at least one multimodal experimental paradigm may necessitate such content: the rubber hand illusion. One upshot of this argument is that Conservatives who claim that the Liberal view intolerably broadens the scope of perceptual illusions, particularly from the perspective of perceptual psychology, should pursue other arguments against that view.

When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’ (Goldstone 1998: 585). In this paper, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory substitution devices concerns (...) what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate. (shrink)

Imagine your mirror-inverted counterpart on Mirror Earth, a perfect mirror image of Earth. Would her experiences be the same as yours, or would they be phenomenally mirror-inverted? I argue, first, that her experiences would be phenomenally the same as yours. I then show that this conclusion gives rise to a puzzle, one that I believe pushes us toward some surprising and philosophically significant conclusions about the nature of perception. When you have a typical visual experience as of something to your (...) left, the following three claims seem very plausible: (1) No one could have an experience phenomenally just like yours without thereby having an experience as of something to her left. (2) Your experience is veridical. (3) Your experience doesn’t differ from that of your mirror-inverted counterpart with respect to veridicality. But (1)-(3) jointly contradict the claim that you and your mirror-inverted counterpart would have the same experiences. I argue that any viable response to this puzzle will embrace the following disjunction: either there is a degree of independence between perceptual phenomenology and representational content, contrary to popular intentionalist views of perception, or spatial subjectivism is true, where spatial subjectivism is the view that the spatial properties presented in perception are either mind-dependent or illusory.

Our main aims in this paper is to discuss and criticise the core thesis of a position that has become known as phenomenal conservatism. According to this thesis, its seeming to one that p provides enough justification for a belief in p to be prima facie justified (a thesis we label Standard Phenomenal Conservatism). This thesis captures the special kind of epistemic import that seemings are claimed to have. To get clearer on this thesis, we embed it, first, in a (...) probabilistic framework in which updating on new evidence happens by Bayesian conditionalization, and second, a framework in which updating happens by Jeffrey conditionalization. We spell out problems for both views, and then generalize some of these to non-probabilistic frameworks. The main theme of our discussion is that the epistemic import of a seeming (or experience) should depend on its content in a plethora of ways that phenomenal conservatism is insensitive to. (shrink)

In this paper, I put forward an argument for the view that emotional responses of esteem to perceived demonstrations of good character represent the perceived character traits as valuable, and hence, as virtues. These esteeming experiences are analogous to perceptual representations in other modalities in their epistemic role as causing, providing content for and justifying beliefs regarding the value of the traits they represent. I also discuss the role that the perceiver’s own character plays in their ability to recognize and (...) respond appropriately to virtue in others, showing that moral virtues are also epistemic virtues when it comes to facilitating knowledge about the character of people we encounter.

I argue for constraining the nomological possibility space of temporal experiences and endorsing the Succession Requirement for agents. The Succession Requirement holds that the basic structure of temporal experience must be successive for agentive subjects, at least in worlds that are law-like in the same way as ours. I aim to establish the Succession Requirement by showing non-successively experiencing agents are not possible for three main reasons, namely that they fail to stand in the right sort of causal relationship to (...) the outcomes of their actions, exhibit the wrong sort of epistemic status for agency, and lack the requisite agentive mental attitude of intentionality. I conclude that agency is incompatible with non-successive experience and therefore we should view the successive temporal structure of experience as a necessary condition for agency. I also suggest that the Succession Requirement may actually extend beyond my main focus on agency, offering preliminary considerations in favor of seeing successive experience as a precondition for selfhood as well. The consequences of the Succession Requirement are wide-ranging, and I discuss various implications for our understanding of agency, the self, time consciousness, and theology, among other things.

The fact that you see some particular object seems to be due to the causal relation between your visual experience and that object, rather than to your experiences’ phenomenal character. On the one hand, whenever some phenomenal element of your experience stands in the right sort of causal relation to some object, your experience presents that object (your experience’s phenomenology doesn’t need to match that object). On the other hand, you can’t have a perceptual experience that presents some object unless (...) you stand in the right sort of causal relation to that object (no matter how closely your experience’s phenomenology matches some object). According to the continuity thesis, property perception is similar to object perception in these two respects. A standard reason to reject the continuity thesis is the assumption that the environmental properties that a perceptual experience presents are determined by its phenomenal properties (which are not determined by the environmental properties that cause the experience). I maintain that the continuity thesis is false but for a different reason: perceptual experiences present both objects and properties via manners of presentation; but, whereas perceptual manners of presentation for objects are purely relational, perceptual manners of presentation for properties are satisfactional.

Casey O’Callaghan has argued that rather than hearing meanings, we hear phonemes. In this note I argue that valuable though they are in an account of speech perception – depending on how we define ‘hearing’ – phonemes either don’t explain enough or they go too far. So, they are not the right tool for his criticism of the semantic perceptual account (SPA).

Perceptual representations pick out individuals and attribute properties to them. This paper considers the role of perceptual attribution in determining or guiding perceptual reference to objects. We consider three extant models of the relation between perceptual attribution and perceptual reference–all attribution guides reference, no attribution guides reference, or a privileged subset of attributions guides reference–and argue that empirical evidence undermines all three. We then defend a flexible-attributives model, on which the range of perceptual attributives used to guide reference shifts adaptively (...) with context. This model underscores the remarkable and dynamic intelligence of our perceptual capacities. We elucidate implications of the model for the boundary between perception and propositional thought.

Theoretical Perspective on Smell will be the first collection of its kind devoted exclusively to philosophical research on olfaction. The contributed essays bring together leading theorists working on smell in a format that allows for inclusive engagement with the emerging field, while also providing those new to the philosophy of smell with a resource to begin their journey . The collection builds upon an international-workshop on the philosophy of smell with the world’s leading theorists, as well as up and coming (...) early career researchers. The aim of Theoretical Perspectives is to solidify the area as an emerging field within general philosophy. The collection is focused around three central topics within philosophy of smell: the place of olfaction in a multisensory world, mapping our odorous environment to our mind, and the content of smell experiences.

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with (...) relatively high integrated information (Phi) compared to veridical visual perceptions. We then present filled/non-filled pairs as an empirical challenge to the integrated information theory of consciousness, which predicts that phenomenologically identical experiences depend on brain processes with identical Phi.

Taking perceptual experience to consist in a relation of acquaintance with the sensible qualities, I argue that the state of being acquainted with a sensible quality is intrinsically a form of knowledge, and not merely a means to more familiar kinds of knowledge, such as propositional or dispositional knowledge. We should accept the epistemic claim for its explanatory power and theoretical usefulness. That acquaintance is knowledge best explains the intuitive epistemic appeal of ‘Edenic’ counterfactuals involving unmediated perceptual contact with reality (...) Perceptual experience, Oxford University Press, 2006). It explains the elusiveness of knowledge gained through new acquaintances. It coheres with the knowledge-like functional role of acquaintance in the special context of evaluative beliefs and evaluative reasoning, where the objects of acquaintance serve as evidence and inferential basis. And, finally, taking acquaintance to be knowledge is theoretically fruitful: it helps vindicate claims about the relationship between knowledge and concern for others we already find intuitive or outright accept. After developing a novel case for the epistemic claim, I respond to two familiar objections against it: namely, that there are no pre-propositional, pre-conceptual cases of perceptual experience that remain epistemically relevant John McDowell: Experience, norm, and nature, Blackwell, 2008); and that the category of knowledge appears gerrymandered once we add ‘object’ knowledge to the epistemological mix, Acquaintance: new essays, Oxford University Press, 2019).

From David Hume's famous puzzle about 'the missing shade of blue' to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics and aesthetics as well as psychology. Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and philosophy of perception. This outstanding Handbook contains (...) twenty-nine specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour. It is organised into six parts: The Importance of Colour to Philosophy The Science and Spaces of Colour Colour Phenomena Colour Ontology Colour Experience and Epistemology Language, Categories and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics and aesthetics, as well as for those interested in conceptual issues in the psychology of colour.

It is common for an object to present different colour appearances to different perceivers, even when the perceivers and viewing conditions are normal. For example, a Munsell chip might look unique green to you and yellowish green to me in normal viewing conditions. In such cases, there are three possibilities. Ecumenism: both experiences are veridical. Nihilism: both experiences are non-veridical. Inegalitarianism: one experience is veridical and the other is non-veridical. Perhaps the most important objection to inegalitarianism is the ignorance objection, (...) according to which inegalitarianism should be rejected because it is committed to the existence of unknowable colour facts. The goal of this paper is to show that ecumenists are also committed to unknowable colour facts. More specifically, I argue that, with the exception of colour eliminativism, all major philosophical theories of colour are committed to unknowable colour facts. (shrink)

In this paper I claim that perceptual discriminatory skills rely on a suitable type of environment as an enabling condition for their exercise. This is because of the constitutive connection between environment and perceptual discriminatory skills, inasmuch as such connection is construed from an ecological approach. The exercise of a discriminatory skill yields knowledge of affordances of objects, properties, or events in the surrounding environment. This is practical knowledge in the first-person perspective. An organism learns to perceive an object by (...) becoming sensitized to its affordances. I call this position ecological disjunctivism. A corollary of this position is that a case of perception and its corresponding case of hallucination—which is similar to the former only in some respects—are different in nature. I show then how the distinguishability problem is addressed by ecological disjunctivism. (shrink)

Perception is one of the most pervasive and puzzling problems in philosophy, generating a great deal of attention and controversy in philosophy of mind, psychology and metaphysics. If perceptual illusion and hallucination are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? How can perception be both internally dependent and externally directed? Perception is an outstanding introduction to this fundamental topic, covering both the perennial and recent work on the problem. Adam (...) Pautz examines four of the most important theories of perception: the sense datum view; the internal physical state view; the representational view; and naïve realism, assessing each in turn. He also discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

Naïve Realism claims that veridical perceptual experiences essentially consist in genuine relations between perceivers and mind-independent objects and their features. The contemporary debate in the philosophy of perception has devoted little attention to assessing one of the main motivations to endorse Naïve Realism–namely, that it is the only view which articulates our ‘intuitive’ conception of perception. In this paper, I first clarify in which sense Naïve Realism is supposed to be ‘naïve’. In this respect, I argue that it is put (...) forward as the only view which can take our introspective knowledge of perception at face value, and I identify the two key features of such introspective knowledge. Second, I challenge the claim that one of these features-namely, that it seems as one could not be in the same perceptual state unless the putative objects of perception existed and were perceived–is introspectively evident. Consequently, I argue that a view of perceptual experience–such as Intentionalism–which denies that this feature is true of perception can still take introspection at face value. This undermines the claim that Naïve Realism is the only account which accommodates our intuitions on the nature of perception. (shrink)

Do we perceptually experience moral properties like rightness and wrongness? For example, as in Gilbert Harman’s classic case, when we see a group of young hoodlums pour gasoline on a cat and ignite it, can we, in the same robust sense, see the action’s wrongness?. Many philosophers have recently discussed this question, argued for a positive answer and/or discussed its epistemological implications. This paper presents a new case for a negative answer by, first, getting much clearer on how such experience (...) could be possible at all; second, responding the only argument for a positive answer; and, finally, arguing that postulation of such experience is explanatorily redundant.

Perceptual constancies have been studied by psychologists for decades, but in recent years, they have also become a major topic in the philosophy of mind. One reason for this surge of interest is Tyler Burge’s (2010) influential claim that constancy mechanisms mark the difference between perception and mere sensitivity, and thereby also the difference between organisms with genuine representational capacities and ‘mindless’ beings. Burge’s claim has been the subject of intense debate. It is becoming increasingly clear, however, that we cannot (...) hope to settle this debate (as well as related debates in the philosophy of mind) without a clear and substantive theoretical account of what perceptual constancies are. In the first part of this paper, I argue that the standard definitions in the literature fall short of providing such an account. Still, as I aim to show in the second part of the paper, by taking a closer look at some of the paradigm examples, it is possible to construct a plausible general account of perceptual constancies that is both clear and substantive, and that can serve as a firm foundation for settling debates like the dispute about Burge’s ‘constancy mechanism criterion’ for perception.

[File is the introduction to the forthcoming monograph] -/- Abstract to monograph -/- How and whether thinking affects perceiving is a deeply important question. Of course it is of scientific interest: to understand the human mind is to understand how we best distinguish its processes, how those processes interact, and what this implies for how and what we may know about the world. And so in the philosopher’s terms, this book is one on both mental architecture and the epistemology of (...) perception. But there is a more human interest. How we make contact with the world, and with one another, is of the most basic of importance. We can make both sensory contact and cognitive contact with the world. The first is traditionally supposed to be determined by the biological nature of our sensory systems, while the second is at least partly determined by us, what we have learned, our experiences, and so on. The most basic claim of the book is that this is mistaken and importantly so. Our sensory contact with the world can also change and in a way that is importantly affected by the cognitive contact that we have, or have had, with the world. Thinking does not just affect perceiving, thinking improves perceiving. If this is true, it changes not only how we should theorize the mind, it changes how we should understand, as individuals, our place in and contact with the world. (shrink)

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual expertise is genuinely perceptual (...) and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

What does it mean to adopt a phenomenological approach when doing philosophy of perception? And what form should such an approach take? I address these questions by first distinguishing three different ways of drawing philosophical conclusions based on phenomenological reflection: 'Humean' phenomenology, which attempts to discern the structure of perceptual experience via reflection on its surface properties; 'Kantian' phenomenology, which aims to provide a priori arguments about the structure perceptual experience must have if it is to possess universally agreed upon (...) manifest properties; and 'Husserlian' phenomenology, which aims to achieve an intuitive grasp of the essential properties of perceptual experience via attempted imaginative variation of its aspects and properties. Drawing on arguments from Merleau-Ponty, I then argue that the shortcomings of each of these approaches motivate a 'Merleau-Pontian' conception of phenomenology as 'radical reflection' - a mode of reflection on perceptual experience that simultaneously attempts to understand the origins and authority of reflection itself. The methodology for philosophy of perception that results is a thoroughly interdisciplinary one, aiming to reconcile philosophical conclusions about the necessary structures of perceptual experience with our best empirical knowledge of the bodily, psychological, cultural and historical contingencies that shape both our experiences and our reflective capacities.

In this chapter, I put forward and sustain an articulation of the notion of bodily skill based on ecological psychology, and I show how it is relevant for the debate between Dreyfus and McDowell about the skillful coping and also for the debate about whether know-how is reducible or not to propositional knowledge. The right metaphor to understand bodily skills is not the computer metaphor but the radio metaphor. These skills results from a process of organism attunement to its environment.

Perceptual disjunctivism, as I regard it in this paper, is the view that veridical perceptions and hallucinations, while indistinguishable via introspection, are states of fundamentally different kinds. This fundamental difference can be spelled out in various ways. According to the view I will be concerned with, it is a fundamental difference in the personal-level structure of both states. Against this version of disjunctivism, I will raise a new challenge. It is a variant of what can be seen as the standard (...) challenge against disjunctivism: how to do justice to the indistinguishability of veridical perceptions and hallucinations. It differs, however, from common versions of this challenge in where it locates the potential incompatibility of disjunctivism with the relevant fact of indistinguishability. Commonly, it is the disjunctivist assumption of a fundamental difference between both kinds of states which is regarded as incompatible with the indistinguishability of these states. In contrast, I will suggest that if hallucinations and veridical perceptions differed in the way proposed by structural disjunctivism, this difference would induce a corresponding difference in the psychological processes of their introspection and that the assumption of such a difference in the manner of introspection is most likely incompatible with a properly formulated indistinguishability claim.

Kant uses terms translatable as ‘synthesis’ and ‘perception’ in different ways in different contexts, which suggests that there are different kinds of synthesis and perception. I propose that there are two main basic functions of perception according to Kant: that of singling out a thing and that of getting perceptually informed about the configuration of the thing’s perceptible features. I argue that the first function is not dependent on the kinds of syntheses Kant analyzes in the Critique of Pure Reason (...) but grounds any such synthesis. I also argue that if singling out a thing is considered to involve synthesis, then the term ‘synthesis’ is identified with a unification of sensory information itself, which is not of much consequence for the transcendental philosopher. The paper also aims to clarify what ‘manifold’ consists in and what the starting point of the ‘synthesis in apprehension’ might be. (shrink)

An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on. Here, I examine the grounds for making much more specific claims about how mental states are structured from constituent parts. For example, the state I am in when I perceive the shape of a mountain ridge may have as constituent parts my representations of the shapes of each peak and saddle (...) of the ridge. More specific structural claims of this sort are a guide to how mental states fall within broader representational kinds. Moreover, these claims have significant implications of their own about semantic, functional, and epistemic features of our mental lives. But what are the conditions on a mental state's having one type of constituent structure rather than another? Drawing on explanatory strategies in vision science, I argue that, other things being equal, the constituent structure of a mental state determines what I call its distributional properties—namely, how mental states of that type can, cannot, or must co‐occur with other mental states in a given system. Distributional properties depend critically on and are informative about the underlying structures of mental states, they abstract in important ways from aspects of how mental states are processed, and they can yield significant insights into the variegation of psychological capacities.

This chapter argues that the only tenable unconscious inferences theories of cognitive achievement are ones that employ a theory internal technical notion of representation, but that once we give cash-value definitions of the relevant notions of representation and inference, there is little left of the ordinary notion of representation. We suggest that the real value of talk of unconscious inferences lies in (a) their heuristic utility in helping us to make fruitful predictions, such as about illusions, and (b) their providing (...) a high-level description of the functional organization of subpersonal faculties that makes clear how they equip an agent to navigate its environment and pursue its goals.

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (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.

According to a certain kind of naïve or folk understanding of physical matter, everyday ‘solid’ objects are composed of a homogeneous, gap-less substance, with sharply defined boundaries, which wholly fills the space they occupy. A further claim is that our perceptual experience of the environment represents or indicates that the objects around us conform to this sort of conception of physical matter. Were this further claim correct, it would mean that the way that the world appears to us in experience (...) conflicts with the deliverances of our best current scientific theories in the following respect: perceptual experience would be intrinsically misleading concerning the structure of physical matter. I argue against this further claim. Experience in itself is not committed to, nor does it provide evidence for, any such conception of the nature of physical matter. The naïve/folk conception of matter in question cannot simply be ‘read-off’ from perceptual appearances. (shrink)

Faultless disagreement and faultless retraction have been taken to motivate relativism for predicates of personal taste, like ‘tasty’. Less attention has been devoted to the question of what aspect of their meaning underlies this relativist behavior. This paper illustrates these same phenomena with a new category of expressions: appearance predicates, like ‘tastes vegan’ and ‘looks blue’. Appearance predicates and predicates of personal taste both fall into the broader category of experiential predicates. Approaching predicates of personal taste from this angle suggests (...) that their relativist behavior is due to their experience-sensitivity, rather than their evaluative meaning. Furthermore, appearance predicates hold interest beyond what they can teach us about predicates of personal taste. Examination of a variety of uses of appearance predicates reveals that they give rise to relativist behavior for a variety of reasons—including some that apply also to other types of expressions, such as epistemic modals and comparative terms. This paper thus serves both to probe the source of relativist behavior in discourse about personal taste, as well as to map out this kind of behavior in the rich and under-explored discourse about appearances.

In discussions of temporal experience, and through reflecting on examples such as those offered, two phenomenological claims are widely – though not unequivocally – accepted: firstly, you perceptually experience motion and change; secondly, while more than a momentary state of affairs (...) is presented in your ongoing perceptual experience, that which is presented nonetheless seems to be of a quite limited temporal extent. These two claims are frequently tied to the notion of the specious present. However, there has recently been a push back against the supposed link between perceived motion and the specious present. I argue that there are two ways of understanding this link, and while one has recently been the target of criticism, the other withstands such criticism. My overarching aim is to clarify the notion of the specious present through a discussion of the notion’s origins, in addition to recent criticism directed at the notion, with the hope of reframing how contemporary debates proceed.
