Perception

Smells seem to offer a great opportunity to restructure the reality of the individual. Yet, the olfactory dimension is rarely part of design strategies in architecture, urban planning or landscape urbanism. As designers, we learn to compose mainly with shapes, shapes whose full scale and effects on our senses we will experience only when constructed. However, we should be primarily concerned with creating spaces that not only open the imagination of the individual but also allow positive moods to thrive. In (...) this scheme, all the senses should be called, not just our vision, as is too often the case. The fields of architecture and environmental design must evolve and train professionals capable of conceptualizing both tangible and intangible forms. In this logic, architectural structures offer a way to call upon our own mindscapes; and within the discipline of design a new field of specialization exists: smellscaping. (shrink)

It is commonly assumed that images, whether in the world or in the head, do not have a privileged analysis into constituent parts. They are thought to lack the sort of syntactic structure necessary for representing complex contents and entering into sophisticated patterns of inference. I reject this assumption. “Image grammars” are models in computer vision that articulate systematic principles governing the form and content of images. These models are empirically credible and can be construed as literal grammars for images. (...) Images can have rich syntactic structure, though of a markedly different form than sentences in language. (shrink)

Descartes was the first to hold that, when we perceive, the representation need not resemble what it represents but should correspond to it. Descartes developed this ground-breaking, influential conception in his work on analytic geometry and then transferred it to his theory of perception. I trace the development of the idea in Descartes’ early mathematical works; his articulation of it in Rules for the Direction of the Mind; his first suggestions there to apply this kind of representation-by-correspondence in the scientific (...) inquiry of colours; and, finally, the transfer of the idea to the theory of perception in The World.

Адекватные знания о буддизме необходимы для образования и культуры любого человека, который не хочет быть просто еще одним отчужденным членом стада, слепо идущего среди технологической революции. Ранний буддизм можно понять с помощью современного языка и знаний и установить его связь с современной мыслью и ее источниками. Благодаря этому становится возможным углубить и расширить наше представление о совместимости этих тысячелетних принципов с нашим современным образом жизни и познания. Требуемое для этого исследование достаточно трудоемкое. Буддизм — это предмет, лежащий в основе гигантской (...) литературной и культурной горы. Чем ближе мы подходим к его первоначальной концепции, тем более глубокие и объемные раскопки нам предстоит провести. (shrink)

I argue that the mainstream formulation of the argument from illusion is invalid, and the Uniqueness Assumption which makes the argument valid is suspicious because the intuition of the assumption stems from common sense which is challenged by the argument from illusion. I show that even if sense data were admitted as objects in illusions, the subject can still perceive something real; she can perceive a composite. This means that the sense-datum account of illusion need not apply to perception.

This article comprehensively examines how information processing relates to attention and consciousness. We argue that no current theoretical framework investigating consciousness has a satisfactory and holistic account of their informational relationship. Our key theoretical contribution is showing how the dissociation between consciousness and attention must be understood in informational terms in order to make the debate scientifically sound. No current theories clarify the difference between attention and consciousness in terms of information. We conclude with two proposals to advance the debate. (...) First, neurobiological homeostatic processes need to be more explicitly associated with conscious information processing, since information processed through attention is algorithmic, rather than being homeostatic. Second, to understand subjectivity in informational terms, we must define information uniqueness in consciousness (e.g., irreproducible information, biologically encrypted information). These approaches could help cognitive scientists better understand conflicting accounts of the neural correlates of consciousness and work toward a more unified theoretical framework. (shrink)

A puzzle about the presentation of objects located at a distance is seen to animate Aristotle's account of transparency in De Anima and De Sensu.

The possibilities of unconscious perception and unconscious bias prompt parallel debates about unconscious mental content. This chapter argues that claims within these debates alleging the existence of unconscious content are made fraught by ambiguity and confusion with respect to the two central concepts they involve: consciousness and content. Borrowing conceptual resources from the debate about unconscious perception, the chapter distills the two conceptual puzzles concerning each of these notions and establishes philosophical strategies for their resolution. It then argues that empirical (...) evidence for unconscious bias falls victim to these same puzzles, but that progress can be made by adopting similar philosophical strategies. Throughout, the chapter highlights paths forward in both debates, illustrates how they serve as fruitful domains in which to study the relationship between philosophy and empirical science, and uses their combined study to further understanding of a general theory of unconscious content.

God in me, God of Me, do I need a Lord, cannot be myself a Lord, a God?

I argue that beliefs based on irresponsibly formed experiences — whose causes were not appropriately regulated by the subject — are doxastically unjustified. Only this position, I claim, accounts for the higher epistemic standard required of perceptual experts. Section I defends this standard and applies it to a pair of cases in which either an expert umpire or a complete novice judge a force play in baseball. I argue that when the latter, but not the former, fails to follow rules (...) about perceiving force plays, their resulting belief is justified. Section II shows that this difference can be explained by the fact that the novice, but not the expert, formed her experience responsibly. Section III shows that alternative explanations of the expert’s unjustified belief — from defeat, reliability, and inference — fail. Section IV shows that the epistemic relevance of responsible experience formation has broad implications for the epistemology of perceptual beliefs. (shrink)

The approximate number system (ANS) enables organisms to represent the approximate number of items in an observed collection, quickly and independently of natural language. Recently, it has been proposed that the ANS goes beyond representing natural numbers by extracting and representing rational numbers (Clarke & Beck 2021a). Prior work has demonstrated that adults and children discriminate ratios in an approximate and ratio-dependent manner, consistent with the hallmarks of the ANS. Here, we use a well-known “connectedness illusion” to provide evidence that (...) these ratio-dependent ratio discriminations are (a) based on the perceived number of items in seen displays (and not just non-numerical confounds), (b) are not dependent on verbal working memory, or explicit counting routines, and (c) may involve representations with a part-whole (or subset-superset) format, like a fraction, rather than a part-part format, like a ratio. These results support and refine the hypothesis that the ANS represents full-blown rational numbers. (shrink)

The distinction between perception and cognition frames countless debates in philosophy and cognitive science. But what, if anything, does this distinction actually amount to? In this introductory article, we summarize recent work on this question. We first briefly consider the possibility that a perception-cognition border should be eliminated from our scientific ontology, and then introduce and critically examine five positive approaches to marking a perception–cognition border, framed in terms of phenomenology, revisability, modularity, format, and stimulus-dependence.

At the intersection of aesthetics and the philosophy of perception lies a problem about representational images. When you look at Vermeer's View of Delft, do you in fact get to see Delft? It would be nice if we could answer in the affirmative, as it would so neatly explain many of our practices in engaging with images. Be it in churches, advertising, or psychology labs, we typically use images as substitutes for the immediate perception of things. Here is what I (...) claim: Images make it possible to see the objects they represent, and they do so because they can function in vision as perceptual mediators. A perceptual mediator is an object of perception by means of which we can perceive something wholly distinct from it. I show that, while such perceptual mediators may be exceptional in vision, in other sensory modalities they occur universally. Our sensory lives would be impoverished without the possibility of perceiving things mediately. In Chapter 1 I identify a fundamental dispute about images. The dispute is about whether images represent by making absent scenes appear to a viewer, or by merely copying the way an object or event looks. Many philosophers favour the idea that images merely copy how things look. In Chapter 2 I explain my dissatisfaction with the copy view. I lay out my main positive proposal in Chapter 3. How does the idea that images make absent objects visible fit with our current concept of perception? I formulate my answer through a study of the other sensory modalities. In audition, it is no mystery that sounds can make other things heard. My arguments forge a connection between images and sounds that has not been explored in recent work on representation or perception. I show how it offers an attractive solution to our problem. In Chapter 4, I argue that moreover, we may regard mediate perception as a purely sensory mode of perception. There is no need to rely on non-sensory or quasi-sensory effects of thought or cognition. Instead, coming to see a painted surface as an image consists in no more than discovering a previously unseen aspect of our visible surroundings. In Chapter 5 I consider at a more general level how visual images contribute to visual perception. Overall, I establish how visual representation has a structural place in our visual world. (shrink)

In this work, we introduce what we believe to be a more sensitive variation of the Metaproblem of consciousness, structured by philosopher Keith Frankish (2017): the Illusion Problem. To do so, we explore the process that leads us to treat each and every quale as an illusion, in addition to showing how qualia are present in most supposedly physicalist theories, which we will later call “Closeted Dualism”. We also emphasize that the illusionist theory is already widely used or considered by (...) philosophers who seek a scientifically plausible way out of the problems of consciousness. Once done, the reader will be ready for the more “technical” part of this article, in which we explore and defend the main concepts and mechanisms of Illusionism. (shrink)

Seeing total darkness is a peculiar perceptual state: in it, the subject is visually aware of something while seeming to fail to be aware of anything. Recent treatments of the topic (Sorensen 2008, Soteriou 2000) leave this particular puzzle unsolved. Here, I attempt a solution. Following Dretske, I begin by suggesting that the perceptual report ‘S sees (total) darkness’ is ambiguous between two distinct kinds of perceptual states: epistemic and non-epistemic. This will lead to an examination of the metaphysics of (...) what is supposed to be seen. I show, on the one hand, the difficulty of reducing the perception of total darkness to the perception of a particular instantiation of a property, and on the other, that it has important similarities with the perception of (non-particular) ‘stuff’. I propose, finally, that the solution to the puzzle might involve postulating a novel ontological status for total darkness: that of a ‘concrete universal’. Potential implications of interest for particularism and for naïve realism are suggested. (shrink)

This book looks at the affective-cognitive roots of how the human mind inquires into the workings of nature and, more generally, how the mind confronts reality. Reality is an infinitely complex system, in virtue of which the mind can comprehend it only in bits and pieces, by making up interpretations of the myriads of signals received from the world by way of integrating those with information stored from the past. This constitutes a piecemeal interpretation by which we assemble our phenomenal (...) reality. In perceiving the complex world and responding to it, the mind invokes the logic of affect and the logic of reason, the former mostly innate and implicit, and the latter generated consciously in explicit terms with reference to mind-independent relations between entities in nature. It is a strange combination of affect and reason that enables us to make decisions and inferences, --- the latter mostly of the inductive type --- thereby making possible the development of theories. Theories are our tool-kits for explaining and predicting phenomena, guiding us along in our journey in life. Theories, however, are defeasible, and need to be constantly updated, at times even radically. In this, the self and the soul are of enormous relevance. The former is the affect-based psychological engine driving all our mental processes, while the latter is the capacity of the conscious mind to examine and reconstruct the self by modulating repressed conflicts. If the soul remains inoperative, all our theories become misdirected and a rot spreads inexorably all around us. (shrink)

The explanatory challenge of sentience is known as the “hard problem of consciousness”: How does subjective experience arise from physical objects and their relations? Despite some optimistic claims, the perennial struggle with this question shows little evidence of imminent resolution. In this article I focus on the “why” rather than on the “how” of sentience. Specifically, why did sentience evolve in organic lifeforms? From an evolutionary perspective this question can be framed: “What adaptive problem(s) did organisms face in their evolutionary (...) past and how were those challenges met? I argue that sentience was a critical component of the adaptive solution (i.e., adopting an agentic stance) to increasingly complex and unpredictable demands placed on vertebrates approximately 500 million years ago (the so-called Cambrian explosion). One consequence of taking an agentic stance is that it freed the organism from its neural moorings, positioning it within phenomenal space outside its brain. (shrink)

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and which ‘subjective’? What (...) properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

Perception solves computationally demanding problems at lightning fast speed. It recovers sophisticated representations of the world from degraded inputs, often in a matter of milliseconds. Any theory of perception must be able to explain how this is possible; in other words, it must be able to explain perception's computational tractability. One of the few attempts to move toward such an explanation has been the information encapsulation hypothesis, which posits that perception can be fast because it keeps computational costs low by (...) forgoing access to information stored in cognition. I argue that we have no compelling reason to believe that encapsulation explains (or even contributes to an explanation of) perceptual tractability, and much reason to doubt it. This is because there exist much deeper computational challenges for perception than information access, and these threaten to make the costs of access irrelevant. If this is right, it undermines a core computational motivation for encapsulation and sends us back to the drawing board for explanations of perceptual tractability. (shrink)

To commemorate the tragic event of Super Typhoon Yolanda (International Name: Haiyan) last 2013, local leaders of the province of Leyte, Philippines, are speculating on establishing a Haiyan Museum in 2023, a decade later. With connotations of ‘dark tourism’, one way to look at the speculative decade-inspired establishment is through Amy Sodaro’s ‘memorial museums’ with the purpose of ‘education-based memorialization.’ Juxtaposing this with Paul Morrow’s philosophical perception of objects in memorial museums as possible provocateurs of repulsive feelings, there is a (...) lingering suspicion of whether exhibits in the museum can really flesh out educational, therapeutic reflections or healing. Then, the crucial question to be addressed is: will this Haiyan Museum house feelings of healing, 10 years later, or trauma? To answer this question, I take insights from survivor-curators or the museum curators of Region VIII, Philippines, who experienced the Haiyan tragedy at, or proximate to, the landfall and aftermath first-hand. The notion of a ‘survivor-curator’ is a vital coinage that would represent a close perception of the museum and its museum objects. The responses are then thematised into a more coherent discussion to see how museums can be spaces of healing in their communal aspect and future museum projects. (shrink)

This paper deals with the Stoic concept of misprinted representation (φαντασία παρατυπωτική), which has received little attention compared to other concepts of Stoic epistemology and philosophy of mind. I aim at showing that a better understanding of this concept is important for grasping some elements of the Stoic account of mental representations that have been ignored or misunderstood in modern Stoic scholarship. First, by clarifying the status of the misprinted representation as a genuine representation, we can understand what it means (...) (and does not mean) to say, from the Stoic point of view, that the intentional object of a representation is the external object that caused it. Second, by understanding this issue, we obtain some resources to deal with the ambiguity of the preposition ἀπό in the definition of cognitive representation. Thus, the concept of misprinted representation proves to be important for appropriately understanding the Stoic concepts of representation and cognitive representation. (shrink)

Relying on euthanasia’s definitionally derived set of propositions to provide its purpose, claims, and benefit, we obtain the core concept. Nonetheless, given its core concept, euthanasia is demonstrated to provide no benefit to the animal to justify its use. Euthanasia 1) cannot possibly, and therefore does not, end unbearable suffering, 2) it fails to hasten death, and 3) it, therefore, provides no perceptible relief to the patient. These findings are significant because the argument’s validity does not permit euthanasia to satisfy (...) its definitionally derived purpose, claims, or benefit on logical grounds. In other words, the argument is that as a form of legalized assisted suicide, euthanasia is wrong but not in the way principled arguments would suggest. Additionally, irrespective of euthanasia actually doing what it claims, if it is allowed to be provisioned, then euthanasia will affect vulnerable populations exactly like nonprincipled arguments claim. Therefore, despite sharing aspects with each type of argument in the extant literature, my argument against euthanasia can be categorized as neither principled nor nonprincipled, which makes it significant because it may be the first of a new category of argument against the concept and practice to enter the discourse on euthanasia. As a corollary, since we prove that unbearable suffering logically entails death, when it is authentic signifying that death is imminent, because euthanasia’s only purpose is to end unbearable suffering by inducing death, euthanasia is completely obviated.

When one visually hallucinates, the object of one’s hallucination is not before one’s eyes. On the standard view, that is because the object of hallucination does not exist, and so is not anywhere. Many different defenses of the standard view are on offer; each have problems. This paper defends the view that there is always an object of hallucination—a physical object, sometimes with spatiotemporally scattered parts.

What do we see in a mirror? There is an ongoing debate whether mirrors present us with images of objects or whether we see, through the mirror, the objects themselves. Roberto Casati has recently argued that there is a categorical difference between images and mirror-reflections. His argument depends on the observation that mirrors, but not paintings, are sensitive to changes in the observer’s prospective. In our paper we scrutinize Casati’s argument and present a modal argument that shows that it cannot (...) establish this conclusion. We suggest that Casati’s line of reasoning suffers from the fact that he does not take dynamic images, i.e., images that change over time, into account. (shrink)

Kant’s distinction between intuitions and concepts attracts perennial interpretive interest. To the extent that they discuss the imagination at all, most Kant scholars maintain that the imagination’s primary role is to generate intuitions. This dissertation argues that “image” (Bild, Einbildung) is an overlooked technical term in Kant’s work and that images—and not intuitions—are products of the imagination. The project explains how, for Kant, the imagination (as image-maker) and the senses (as intuition-maker) make distinct but essential contributions to cognition and perception. (...) I begin by showing that “image” is a terminologically marked notion in Kant, and that the imagination is responsible for generating images (chapter 1). I call these claims the Image Thesis. I then show that for Kant, intuitions are representations that depend only on the senses for their essential features (chapter 2). I call this the Strong Independence Thesis. -/- How should we understand Kant’s ubiquitous references to the imagination, then? I argue that we should understand the imagination’s activities as image-producing activities (chapter 3). I argue that images and intuitions are fundamentally distinct representations, which I label the Distinctness Thesis. Though intuitions and images are had by both rational and non-rational beings, the capacity for consciousness or apperception found in rational beings makes a difference in the structure of images but not the structure of intuitions (chapter 4). I call this the penetration view of the imagination. With this account of images in hand, I indicate why images are a necessary ingredient in theoretical cognition for Kant (chapter 5). I call this the Image-Centric Cognition Thesis. The result is a novel account of sensibility—the counterpart of the understanding—that recognizes Kant’s systematic discussion of mental imagery.

The primary intention of this book is to elucidate the relations between sensory perception and art as a form of knowledge. This enables us to understand how different kinds of art are given their meaning not only from observation, resemblance and reason but also from an artist’s sensitivity to the inner form of sensory experience as it is realized in perception, reflection, memory and imagination. By assuming a number of different points of view, Part 1 shows how the physical object (...) and the act of sensory perception are logically interdependent, and I give my elaboration of this argument two kinds of emphasis. In the first place, it opposes all arguments that support a merging of the mental and physical, as in idealism, materialism, neutral monism and panpsychism. A conceptual distinction is observed because sensory perception gives the physical object its identity. This idea also implies that the physical object is only realized by sentient life - self-aware inner life and a world become possible simultaneously. The second emphasis concerns the mind-body problem, and towards the end of Part 1 I offer an argument which places this problem in a certain light by representing the brain not as a physical counterpart to inner experience but as essentially instrumental to perception and self-awareness, and related experience. The argument in Part 2 is distinguished by a sense of continuity between the nature of sensory perception and the formal resources of artists in both physical and literary media. Hence, in a discussion of Titian’s Assumption of the Virgin, I indicate ways in which the painter conveys the inner experience and character of the figures in the painting by means of compositional design, light and colour, and thereby uses these and other sensuous resources to portray human life and experience. This is followed by a discussion of two sonnets by Shakespeare, in which the same general aim is pursued by using the literary resources of figurative language. Finally, a discussion of Hamlet shows how, in this work, the augmentation of figurative language by dramatic form strengthens the view that art can provide a form of knowledge that is based as completely upon intuition about our sensory experience as it is upon reason and observation. Just as my (true) perception of a cup as a vessel for drinking tea or coffee arises immediately from past experience, so the dramatist can see immediately from his or her past experience how a character might perceive things and behave. -/- .

I argue that Sellars's philosophy of perception can be reconciled with recent work in enactive cognitive science. Sellars's critical realism holds that we perceive physical objects with perceptible properties as causally mediated by how these objects affect our sensory receptors. I argue that this theory, while basically right, downplays the role of embodiment in perception: perception essentially involves sensorimotor abilities. I argue that embodied critical realism can resolve the debate between Coates and Noe.

Heutige Sprache besteht aus versteinerten Formen, denen zu widersprechen für die meisten Menschen widersinnig erscheint.

Weil die Bewußtwerdung abgewehrter Inhalte ein Vorgang ist, der im Verlauf psychoanalytischer Behandlung oder Selbstbefragung bzw. Selbstinfragestellung zustande kommt, versuche ich die wesentlichen Ursachen für psychischen Widerstand aufzuzeigen.

Kahneman's 'Asian disease' has nothing to do with Asians or their diseases; it is disrespectful of the basic principles of psychology. The attendant research--fooling people--is not science. Here I show how to build a science of the mind.

Jaakko Hintikka proposed treating objectual perception sentences, such as “Alice sees Bob,” as de re propositional perception sentences. Esa Saarinen extended Hintikka’s idea to eventive perception sentences, such as “Alice sees Bob smile.” These approaches, elegant as they may be, are not philosophically neutral, for they presuppose, controversially, that the content of all perceptual experiences is propositional in nature. The aim of this paper is to propose a formal treatment of objectual and eventive perception sentences that builds on Hintikka’s modal (...) approach to propositional attitude ascriptions while avoiding controversial assumptions on the nature of perceptual experiences. Despite being simple and theoretically frugal, our approach is powerful enough to express a variety of interesting philosophical views about propositional, objectual, and eventive perception sentences, thus enabling the study of their inferential relationships.

Strong or Pure Intentionalism is the view that the phenomenal character of a conscious experience is exhaustively determined by its intentional content. Contrastingly, impure intentionalism holds that there are also non content-based aspects or features which contribute to phenomenal character. Conscious attention is one such feature: arguably its contribution to the phenomenal character of a given conscious experience are not exhaustively captured in terms of what that experience represents, that is in terms of properties of its intentional object. This paper (...) attempts to get clearer on the phenomenal contribution of conscious attention. In doing so it considers and sets aside two prominent impure intentionalist accounts, namely the Phenomenal Structure view of Sebastien Watzl, and the Demonstrative Awareness view of Wayne Wu. As an alternative I outline a Modification view, which draws on ideas in Husserlian phenomenology. On this view, we should think of the phenomenal contribution of conscious attention in terms of attentive modifications of what I call a ‘pre-attentive phenomenal field’. I develop this view and highlight its benefits over alternatives. (shrink)

There is a long history of philosophers granting a privileged epistemic status to cognition of directly present objects. In this paper, I examine three important historic accounts which provide different models of this cognitive state and its connection with its objects: that of the Stoics, who are corporealists and think that ordinary perception may have an epistemically privileged status, but who seem to struggle to accommodate non-perceptual cognizance; that of Augustine, who thinks that incorporeal objects are directly present to us (...) in ‘intellectual perception’, and that, by way of contrast, ordinary sense-perception does not have a privileged epistemic status; and that of William of Ockham, who allows for unmediated action at a distance and is fairly generous about what counts as being directly present.

East Asians and Westerners differ in various aspects of perception and cognition. For example, visual memory for East Asians is believed to be more influenced by the contextual aspects of a scene than is the case for Westerners (Masuda & Nisbett, 2001). There are also differences in visual search: for Westerners, search for a long line among short is faster than for short among long, whereas this difference does not appear to hold for East Asians (Ueda et al., submitted). However, (...) it is unclear how these group-level differences originate. To investigate the extent to which they depend upon environment, we tested visual search and visual memory in East Asian immigrants who had lived in Canada for different amounts of time. Recent immigrants were found to exhibit no search asymmetry, unlike Westerners who had spent their lives in Canada. However, immigrants who had lived in Canada for more than two years showed performance comparable to that of Westerners. These differences could not be explained by the general analytic/holistic processing distinction believed to differentiate Westerners and East Asians, since all observers showed a strong holistic tendency for visual recognition. Results instead support the suggestion that exposure to a new environment can significantly affect the particular processes used to perceive a given stimulus. (shrink)

As observers, we generally have a strong impression of seeing everything in front of us at any moment. But compelling as it is, this impression is false – there are severe limits to what we can consciously experience in everyday life. Much of the evidence for this claim has come from two phenomena: change blindness (CB) and inattentional blindness (IB). -/- CB refers to the failure of an observer to visually experience changes that are easily seen once noticed. This can (...) happen even if the changes are large, constantly repeat, and the observer has been informed that they will occur. A related phenomenon is IB – the failure to visually experience an object or event when attention is directed elsewhere. For example, observers may fail to notice an unexpected object that enters their visual field, even if this object is large, appears for several seconds, and has important consequences for the selection of action. -/- Both phenomena involve a striking failure to report an object or event that is easily seen once noticed. As such, both are highly counterintuitive, not only in the subjective sense that observers have difficulty believing they could fail so badly at seeing but also in the objective sense that these findings challenge many existing ideas about how we see. But as counterintuitive as these phenomena are, progress has been made in understanding them. Indeed, doing so has allowed us to better understand the limitations of human perception in everyday life and to gain new insights into how our visual systems create the picture of the world that we experience each moment our eyes are open.

Our visual experience of the world is one of diverse objects and events, each with particular colors, shapes, and motions. This experience is so coherent, so immediate, and so effortless that it seems to result from a single system that lets us experience everything in our field of view. But however appealing, this belief is mistaken: there are severe limits on what can be visually experienced. -/- For example, in a display for air-traffic control it is important to track all (...) moving items. For a single item, this can be done without problem. Three or four can also be tracked, although some degree of effort may be needed. As the number is increased further, accurate tracking becomes more and more difficult—and eventually, impossible. Performance is evidently affected by a factor within the observer which enables certain kinds of perception to occur, but is limited in some way. This factor is generally referred to as attention. -/- At various times, attention has been associated with clarity of perception, intensity of perception, consciousness, selection, or the allocation of a limited “resource” enabling various operations (see Hatfield, 1998). During the past several decades, considerable progress has been achieved by focusing on the idea of selection (Broadbent, 1982). In particular, attention can be productively viewed as contingently selective processing. This can be embodied in various ways by various processes—there need not be a single quantity identified with all forms of attention, or a single site where it operates (Allport, 1993; Tsotsos, 2011). Although “paying attention” is often considered to be a unitary operation, it may simply refer to the control of one or more selective processes, ideally in a co-ordinated way. While this view has some cost in terms of conceptual simplicity, it can help make sense of a large set of phenomena. -/- This article surveys several of the major issues in our understanding of attention and how it relates to perception. It focuses on vision, since many—if not all—considerations are similar for all sensory modalities, and the level of understanding achieved in this domain is currently the most advanced. (shrink)

Starting from Brentano’s classical characterization of intentionality, we review the radical enactivist proposal about basic cognition and show that the underlying assumption that stripping teleosemantics of its representationalist commitments results in no explanatory loss is unwarranted. Significant features of basic cognition are lost, or so we argue, with the RECtification of teleosemantics that are retrieved by means of an alternative dubbed metaphysically non-committal content-ascriptivism.

In theoretical work about the language of personal taste, the canonical example is the simple predicate of personal taste, 'tasty'. We can also express the same positive gustatory evaluation with the complex expression, 'taste good'. But there is a challenge for an analysis of 'taste good': While it can be used equivalently with 'tasty', it need not be (for instance, imagine it used by someone who can identify good wines by taste but doesn't enjoy them). This kind of two-faced behavior (...) systematically arises with complex sensory-evaluative predicates, including those with other appearance verbs, such as 'look splendid' and 'sound nice'. I examine two strategies for capturing these different uses: one that posits an ambiguity in appearance verbs, and one that does not. The former is in line with an approach to 'look'-statements prominent in work in philosophy of perception, and I consider how the motivation given in that tradition carries over to the present context. I then show how the data used to support the verbal ambiguity approach can equally be captured on the second strategy, which appeals only to independently-motivated flexibility in adjective meaning. I close by discussing some considerations that are relevant for choosing between the two options. (shrink)

As neither a classical naturalist nor a non-naturalist, Merleau-Ponty appears to be a moderate or liberal naturalist. But can a phenomenologist really be a naturalist, even a liberal one? A lot hinges on how we tease this out, both as to whether it is plausible to claim Merleau-Ponty as a liberal naturalist (I argue it is), and as to whether it is an attractive and coherent position. Indeed, despite its important challenges to orthodox naturalism, there are arguably two traps to (...) avoid. If it becomes too liberal, we get: dualism or an ontological pluralism that is difficult to distinguish from a constructivism; or, in seeking to sidestep that metaphysical dilemma, there is sometimes an insistence on an overly neat methodological separation between description/understanding and explanation that is belied in practice (both scientific and philosophical). It is doubtful that such positions can legitimately claim to be naturalist in orientation, liberal or not. Merleau-Ponty’s philosophy avoids these traps, however, and it is thus a useful resource for contemporary work trying to navigate between scientific naturalism and non-naturalism. (shrink)

There is a lesson from the woods--Bollywood, Kollywood, Mollywood, and Tollywood--of make-believe, which speaks to the core concern of science: the practice of science. Puspha, an Indian movie that brought the movie industry to its senses, with its global popularity has this to say: Be thyself; keep it real. Situated in a remote region aeons apart from the vast concrete and intimate plastic world we are familiar with, the happenings in the distant and alien universe of discourse--a hamlet adjacent to (...) tribals, forest, and nature--is surprisingly universally relatable. Here I show how the unity of being and the attendant naturality of becoming or, in the words of Tolkien, "the inner consistency of reality" of Pushpa is what made people all over the world relate to each and every character/scene in Pushpa. In doing so, I bring out its (arts and/or humanities) relevance to the practice of science in general and science policy in particular, with emphasis on changing human behaviour, especially in the context of COVID.

Bence Nanay, in Aesthetics as Philosophy of Perception, and Murray Smith, in Film, Art, and the Third Culture, have given us a pair of rich and interesting works about the relationships between aesthetics and the sciences of mind. Nanay’s work focuses on perception and attention, while Smith’s addresses the relations among experiential, psychological, and neuroscientific understandings of a wide range of aesthetically relevant phenomena, particularly as they occur in film. These books make a valuable contribution to a project that remains (...) fledgling: that of taking seriously the relevance of the sciences to our conceptions and explanations of experiential phenomena in aesthetics and the philosophy of art. I will focus on a specific issue from each of these works. Nanay offers an account of aesthetic experience that ties it closely to the concepts of focused and distributed attention that are invoked in the sciences of perception. While I agree with Nanay that attention should play a central role in accounts of aesthetic experience, I raise questions about his specific account of the relationship. With Smith, we zoom out to a broader issue, that of the mutual explanatory relationships among phenomenological, functional/cognitive, and neurophysiological observations in our aesthetic theorizing. Smith makes a strong claim that all three of these levels are essential and irreducible, and none is subsidiary to the others. I argue that given the current state of the science, we should not regard neurophysiological observations as being on a par with observations at the other two levels. I also raise some doubts about the prospect of neurophysiological data making an independent contribution to aesthetic theorizing, even once the science is far more advanced. (shrink)

A compositional theory of perceptual representations would explain how the accuracy conditions of a given type of perceptual state depend on the contents of constituent perceptual representations and the way those constituents are structurally related. Such a theory would offer a basic framework for understanding the nature, grounds, and epistemic significance of perception. But an adequate semantics of perceptual representations must accommodate the holistic nature of perception. In particular, perception is replete with context effects, in which the way one perceptually (...) represents one aspect of a scene (including the position, size, orientation, shape, color, motion, or even unity of an object) normally depends on how one represents many other aspects of the scene. The ability of existing accounts of the semantics of perception to analyze context effects is at best unclear. Context effects have even been thought to call into question the very feasibility of a systematic semantics of perception. After outlining a compositional semantics for a rudimentary set of percepts, I draw on empirical models from perceptual psychology to show how such a theory must be modified to analyze context effects. Context effects arise from substantive constraints on how perceptual representations can combine and from the different semantic roles that perceptual representations can have. I suggest that context effects are closely tied to the objectivity of perception. They arise from a perceptual grammar that functions to facilitate the composition of reliably accurate representations in an uncertain but structured world. (shrink)
