One way to characterize the special relation that one has to one's own body is to say that only one's body appears to one from the inside. Although widely accepted, the nature of this specific experiential mode of presentation of the body is rarely spelled out. Most definitions amount to little more than lists of the various body senses (including senses of posture, movement, heat, pressure, and balance). It is true that body senses provide a kind of informational access to (...) one's own body, which one has to no other bodies, by contrast to external senses like vision, which can take many bodies as their object. But a theory of bodily awareness needs to take into account recent empirical evidence that indicates that bodily awareness is infected by a plague of multisensory effects, regardless of any dichotomy between body senses and external senses. Here I will argue in favour of a multimodal conception of bodily awareness. I will show that the body senses fail to fully account for the content of bodily experiences. I will then propose that vision helps compensate for the insufficiencies of the body senses in people who can see. I will finally argue that the multimodality of bodily experiences does not prevent privileged access to one's body. (shrink)

This article examines what is known about the cognitive science of working memory, and brings the findings to bear in evaluating philosophical accounts of central cognitive processes of thinking and reasoning. It is argued that central cognition is sensory based, depending on the activation and deployment of sensory images of various sorts. Contrary to a broad spectrum of philosophical opinion, the central mind does not contain any workspace within which goals, decisions, intentions, or non-sensory judgments can be active.Introduction: philosophers’ commitmentsMost (...) philosophers believe that our so-called “personal-level” propositional attitudes—our personal judgments, beliefs, goals, values, decisions, and intentions—are consciously accessible. Many will also allow, of course, that some of the processing that takes place within our perceptual faculties is inaccessible to us; and many will grant the possibility of unconscious attitudes, as well as processes of inference and decision mak.

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

This paper concerns the question of which properties figure in the contents of perceptual experience. According to conservatives, only low-level properties figure in the contents of perceptual experience. Liberals, on the other hand, claim that high-level properties, such as natural kind properties, artifacts, and even moral properties, can figure in the contents of perceptual experience. I defend a novel argument in favor of liberalism, the Epistemic Argument, which hinges on two crucial claims. The first is that many perceptual experiences of (...) even neurotypical human beings can justify beliefs in high-level properties without providing justification for their low-level constituents. The second claim, roughly, is that any experience that alone provides (defeasible) justification for beliefs about some property p, other things being equal, has p as part of its content. In short, certain perceptual experiences represent high-level but not low-level properties, which entails that liberalism is true. (shrink)

When one contrasts pain with the classic five senses, discussions generally focus on vision, which is taken as the paradigmatic example of perception. An intentionalist might argue that if the phenomenal difference between feeling and seeing bodily disturbances cannot be explained at the level of the content, it can be so at the level of the mode of presentation, and more particularly at the level of the structure of the spatial phenomenology of pain. Here I will argue that the spatial (...) phenomenology of pain shares some key features with touch by contrast to sight, but these similarities should not make us neglect major differences between these two types of bodily sensations. I shall then draw the consequences of these differences for the awareness of one’s body as one’s own. In brief, to fix the boundaries of the body that one experiences as one’s own, one must answer two questions: where does the body stop, and the rest of world start? and what matters for self-preservation? I will suggest that touch primarily answers the first question, whereas pain primarily answers the second question. (shrink)

Recently, several theorists have proposed that we can perceive a range of high-level features, including natural kind features (e.g., being a lemur), artifactual features (e.g., being a mandolin), and the emotional features of others (e.g., being surprised). I clarify the claim that we perceive high-level features and suggest one overlooked reason this claim matters: it would dramatically expand the range of actions perception-based theories of action might explain. I then describe the influential phenomenal contrast method of arguing for high-level perception (...) and discuss some of the objections that have been raised against this strategy. Finally, I describe two emerging defenses of high-level perception, one of which appeals to a certain class of perceptual deficits and one of which appeals to adaptation effects. I sketch a challenge for the latter approach. (shrink)

[Penultimate draft] I present the perceptualist/representationalist theories of pain in broad outline and critically examine them in light of a competing view according to which awareness of pain is essentially introspective. I end the essay with a positive sketch of a naturalistic proposal according to which pain experiences are intentional but not fully representational. This proposal makes sense of locating pains in body parts as well as taking pains as subjective experiences.

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)

Multisensory processing encompasses all of the various ways in which the presence of information in one sensory modality can adaptively influence the processing of information in a different modality. In Part I of this survey article, I begin by presenting a cartography of some of the more extensively investigated forms of multisensory processing, with a special focus on two distinct types of multisensory integration. I briefly discuss the conditions under which these different forms of multisensory processing occur as well as (...) their important perceptual consequences and interrelations. In Part II, I then turn to examining of some of the different possible ways in which the structure of conscious perceptual experience might also be characterized as multisensory. In addition, I discuss the significance of research on multisensory processing and multisensory consciousness for philosophical attempts to individuate the senses. (shrink)

La autora presenta una critica a la concepcion clasica de los sentidos asumida por la mayoria de autores naturalistas que pretenden explicar el contenido mental. Esta crítica se basa en datos neurobiologicos sobre los sentidos que apuntan a que estos no parecen describir caracteristicas objetivas del mundo, sino que actuan de forma ʼnarcisita', es decir, representan informacion en funcion de los intereses concretos del organismo.El articulo se encuentra también en: Bechtel, et al., Philosophy and the Neuroscience.

This paper presents forms of multimodal perceptual experience that undermine the claim that each aspect of perceptual experience is modality specific. In particular, it argues against the thesis that all phenomenal character is modality specific (even making an allowance for co-conscious unity). It concludes that a multimodal perceptual episode may have phenomenal features beyond those that are associated with the specific modalities.

Are bodily self-ascriptions immune to error through misidentification? According to the Inside mode view, one cannot be mistaken about whose body part it is when experiencing them from the inside. Here I shall consider two possible objections to bodily immunity. On the one hand, I shall briefly envisage two cases of misidentification: somatoparaphrenia and the Rubber Hand illusion. I shall show that none of them challenges the immunity principle. On the other hand, I shall highlight a more serious issue for (...) bodily immunity, namely, the multimodal nature of bodily self-knowledge. Very few bodily self-ascriptions are based on grounds that are purely or exclusively from the inside. I shall evaluate the consequences of multimodality for bodily immunity. (shrink)

There seems to be no dimension of bodily awareness that cannot be disrupted. To account for such variety, there is a growing consensus that there are at least two distinct types of body representation that can be impaired, the body schema and the body image. However, the definition of these notions is often unclear. The notion of body image has attracted most controversy because of its lack of unifying positive definition. The notion of body schema, onto which there seems to (...) be a more widespread agreement, also covers a variety of sensorimotor representations. Here, I provide a conceptual analysis of the body schema contrasting it with the body image as well as assess whether the body schema can be specifically impaired, while other types of body representation are preserved; and the body schema obeys principles that are different from those that apply to other types of body representation.

The “body image” is a putative mental representation of one’s own body, including structural and geometric details, as well as the more familiar visual and affective aspects. Very little research has investigated how we learn the structure of our own body, with most researchers emphasising the canonical visual representation of the body when we look at ourselves in a mirror. Here, we used non-visual self-touch in healthy participants to investigate the possibility that primary sensorimotor experience may influence cognitive representations of (...) one’s own body structure. Participants used the fingers of one hand , to touch the fingers of the other . A conflict between the experience of the active and passive hand was introduced by experimenter interleaving their fingers with the fingers of the participant’s passive hand. This led to the active hand experiencing that it touched more fingers than the passive hand felt it was being touched by. The effects on representation of body structure were assessed using an implicit measure based on Kinsbourne and Warrington’s ‘in-between task’. We found an underestimation of the number of fingers in the central part of the hand specifically linked to the experience of self-touch. This pattern of results corresponds to the experience of the passive hand, but not the active hand. Nevertheless, comparable reorganisation of fingers within the hand representation was found for both active and passive hands. We show that primary sensorimotor experience can modify the representation of body structure. This modification is driven by the passive experience of being touched, rather than by the active experience of touching. We believe this is the first experimental study of effects of self-touch on the mental representation of the body. (shrink)

What grounds my experience of my body as my own? The body that one experiences is always one’s own, but it does not follow that one always experiences it as one’s own. One might even feel that a body part does not belong to oneself despite feeling sensations in it, like in asomatognosia. The article aims at understanding the link between bodily sensations and the sense of ownership by investigating the role played by the body schema.

A central debate in the philosophy of perception concerns the range of properties that can be represented in perceptual experience. Are the contents of perceptual experience restricted to ‘low-level’ properties such as location, shape and texture, or can ‘high-level’ properties such as being a tomato, being a pine tree or being a watch also be represented in perceptual experience? This paper explores the bearing of gist perception on the admissible contents debate, arguing that it provides qualified support for the claim (...) that certain kinds of high-level properties—such as being a natural scene —can be perceptually represented.

Abstract: This paper seeks to establish whether the cognitive penetration of experience is compatible with experience having nonconceptual content. Cognitive penetration occurs when one’s beliefs or desires affect one’s perceptual experience in a particular way. I examine two different models of cognitive penetration and four different accounts of the distinction between conceptual and nonconceptual content. I argue that one model of cognitive penetration—“classic” cognitive penetration—is compatible with only one of the accounts of nonconceptual content that I identify. I then consider (...) the other model of cognitive penetration—cognitive penetration “lite”. I provide reasons to think that this is compatible with three accounts of nonconceptual content. Moreover, I argue that the account of nonconceptual content that it is not compatible with is a spurious notion of nonconceptual content that ought to be abandoned. Thus, I claim that cognitive penetration lite is compatible with all reasonable specifications of nonconceptual content. (shrink)
