Recent imaging results suggest that individuals automatically share the emotions of others when exposed to their emotions. We question the assumption of the automaticity and propose a contextual approach, suggesting several modulatory factors that might influence empathic brain responses. Contextual appraisal could occur early in emotional cue evaluation, which then might or might not lead to an empathic brain response, or not until after an empathic brain response is automatically elicited. We propose two major roles for empathy; its epistemological role (...) is to provide information about the future actions of other people, and important environmental properties. Its social role is to serve as the origin of the motivation for cooperative and prosocial behavior, as well as help for effective social communication. (shrink)
Theories of embodied cognition abound in the literature, but it is often unclear how to understand them. We offer several interpretations of embodiment, the most interesting being the thesis that mental representations in bodily formats (B-formats) have an important role in cognition. Potential B-formats include motoric, somatosensory, affective and interoceptive formats. The literature on mirroring and related phenomena provides support for a limited-scope version of embodied social cognition under the B-format interpretation. It is questionable, however, whether such a thesis can (...) be extended. We show the limits of embodiment in social cognition. (shrink)
There are two main pathways to investigate the sense of body ownership, (i) through the study of the conditions of embodiment for an object to be experienced as one's own and (ii) through the analysis of the deficits in patients who experience a body part as alien. Here, I propose that E is embodied if some properties of E are processed in the same way as the properties of one's body. However, one must distinguish among different types of embodiment, and (...) only self-specific embodiment can lead to feelings of ownership. I address issues such as the functional role and the dynamics of embodiment, degrees and measures of ownership, and shared body representations between self and others. I then analyse the interaction between ownership and disownership. On the one hand, I show that there is no evidence that in the Rubber Hand Illusion, the rubber hand replaces the biological hand. On the other hand, I argue that the sense of disownership experienced by patients towards their body part cannot be reduced to the mere lack of ownership. (shrink)
We offer an account of empathetic pain that preserves the distinctions among standard pain, contagious pain, empathetic pain, sympathy for pain, and standard pain ascription. Vicarious experiences of both contagious and empathetic pain resemble to some extent experiences of standard pain. But there are also crucial dissimilarities. As neuroscientific results show, standard pain involves a sensorimotor and an affective component. According to our account, contagious pain consists in imagining the former, whereas empathetic pain consists in imagining the latter. We further (...) argue that awareness of another's standard pain is part of empathetic pain, but empathetic awareness of another's standard pain differs from believing that another is in standard pain.

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. (shrink)
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)
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.
The distinction between the body schema and the body image has become the stock in trade of much recent work in cognitive neuroscience and philosophy. Yet little is known about the interactions between these two types of body representations. We need to account not only for their dissociations in rare cases, but also for their convergence most of the time. Indeed in our everyday life the body we perceive does not conflict with the body we act with. Are the body (...) image and the body schema then somehow reshaping each other or are they relatively independent and do they only happen to be congruent? On the basis of the study of bodily hallucinations, we consider which model can best account for the body schema/body image interactions. (shrink)
How do I know that I am the person who is moving? According to Wittgenstein, the sense of agency involves a primitive notion of the self used as subject, which does not rely on any prior perceptual identification and which is immune to error through misidentification. However, the neuroscience of action and the neuropsychology of schizophrenia show the existence of specific cognitive processes underlying the sense of agency—the “Who” system —which is disrupted in delusions of control. Yet, we have to (...) be careful in the interpretation of such clinical symptoms, which cannot be so easily reduced to deficit of action monitoring or to lack of action awareness. Moreover, we should refine the definition of the sense of agency by distinguishing the sense of initiation and the sense of one’s own movements. A conceptual analysis of the empirical data will lead us to establish the taxonomy of the different levels of action representations. (shrink)
Does the existence of body representations undermine the explanatory role of the body? Or do certain types of representation depend so closely upon the body that their involvement in a cognitive task implicates the body itself? In the introduction of this special issue we explore lines of tension and complement that might hold between the notions of embodiment and body representations, which remain too often neglected or obscure. To do so, we distinguish two conceptions of embodiment that either put weight (...) on the explanatory role of the body itself or body representations. We further analyse how and to what extent body representations can be said to be embodied. Finally, we give an overview of the full volume articulated around foundational issues (How should we define the notion of embodiment? To what extent and in what sense is embodiment compatible with representationalism? To what extent and in what sense are sensorimotor approaches similar to behaviourism?) and their applications in several cognitive domains (perception, concepts, selfhood, social cognition). (shrink)
The body is made up of parts. This basic assumption is central in most neuroscientific studies of bodily sensation, body representation and motor action. Yet, the assumption has rarely been considered explicitly. We may indeed ask how the body is internally segmented and how body parts can be defined. That is, how can we sketch the mereology of the body? Here we distinguish between a somatosensory mereology and a motor mereology.
Since Aristotle, touch has been found especially hard to define. One of the few unchallenged intuitions about touch, however, is that tactile awareness entertains some close relationship with bodily awareness. This chapter considers the relation between touch and bodily awareness from two different perspectives: the body template theory and the body map theory. According to the former, touch is defined by the fact that tactile content matches proprioceptive content. We raise some objections against such a bodily definition of touch and (...) suggest, as an alternative, reviving the proposal according to which touch is essentially a sense of pressure. According to the body map theory, tactile sensations are localized within the frame of reference provided by the mental representation of the space of the body. We argue that this approach to the location of bodily sensations fares better that the Local Sign theory that denies intrinsic spatiality to touch. (shrink)
In this paper, we attempt to make a distinction between egocentrism and allocentrism in social cognition, based on the distinction that is made in visuo-spatial perception. We propose that it makes a difference to mentalizing whether the other person can be understood using an egocentric (‘‘you'') or an allocentric (‘‘he/ she/they'') stance. Within an egocentric stance, the other person is represented in relation to the self. By contrast, within an allocentric stance, the existence or mental state of the other person (...) needs to be represented as independent from the self. We suggest here that people with Asperger syndrome suffer from a disconnection between a strong naı¨ve egocentric stance and a highly abstract allocentric stance. We argue that the currently used distinction between first-person and third-person perspective-taking is orthogonal to the distinction between an egocentric and an allocentric stance and therefore cannot serve as a critical test of allocentrism.

Abstract: What grounds the experience of our body as our own? Can we rationally doubt that this is our own body when we feel sensations in it? This article shows how recent empirical evidence can shed light on issues on the body and the self, such as the grounds of the sense of body ownership and the immunity to error through misidentification of bodily self-ascriptions. In particular, it discusses how bodily illusions (e.g., the Rubber Hand Illusion), bodily disruptions (e.g., somatoparaphrenia), (...) and the multimodal nature of bodily self-knowledge challenge a classic view of ownership and immunity that puts bodily sensations at its core.

In a 1962 article, ‘On Sensations of Position’, G. E. M. Anscombe claimed that we do not feel our legs crossed; we simply know that they are that way. What about the sense of bodily ownership? Do we directly know that this body is our own, or do we know it because we feel this body that way? One may claim, for instance, that we are we aware that this is our own body thanks to our bodily experiences that ascribe (...) the property of myness to the body that they represent. Here I approach this issue from the perspective of the debate on the admissible content of perception, appealing to the method of phenomenal contrast. After rejecting the myness hypothesis, I criticize alternative accounts of the contrast in somatosensory, cognitive, and agentive terms. I conclude that the phenomenology of ownership consists in the affective awareness of the unique significance of the body for survival. (shrink)
Philosophy of perception is guilty of focusing on the perception of far space, neglecting the possibility that the perception of the space immediately surrounding the body, which is known as peripersonal space, displays different properties. Peripersonal space is the space in which the world is literally at hand for interaction. It is also the space in which the world can become threatening and dangerous, requiring protective behaviours. Recent research in cognitive neuroscience has yielded a vast array of discoveries on the (...) multisensory and sensorimotor specificities of the processing of peripersonal space. Yet very little has been done on their philosophical implications. Here I will raise the following question: in what manner does the visual experience of a big rock close to my foot differ from the visual experience of the moon in the sky? (shrink)
Pain is unpleasant. It is something that one avoids as much as possible. One might then claim that one wants to avoid pain because one cares about one's body. On this view, individuals who do not experience pain as unpleasant and to be avoided, like patients with pain asymbolia, do not care about their body. This conception of pain has been recently defended by Bain [2014] and Klein [forthcoming]. In their view, one needs to care about one's body for pain (...) to have motivational force. But does one need to care about one's body qua one's own? Or does one merely need to care about the body that happens to be one's own? In this paper, I will consider various interpretations of the notion of bodily care, in light of a series of pathological cases in which patients report pain in a body part that they do not experience as their own. These cases are problematic if one adopts a first-personal interpretation of bodily care, according to which pain requires one to care about what is represented as one's own body. Th.. (shrink)
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)

Self-knowledge seems to be radically different from the knowledge of other people. However, rather than focusing on the gap between self and others, we should emphasize their commonality. Indeed, different mirror matching mechanisms have been found in monkeys as well as in humans showing that one uses the same representations for oneself and for the others. But do these shared representations allow one to report the mental states of others as if they were one''s own? I intend in this essay (...) to address the epistemic problem of other minds by developing Ayer''s notion of co-consciousness. (shrink)
The enactive approach aims at providing a unified account of perceptual experiences in terms of bodily activities. Most enactive arguments come from the analysis of visual experiences, but there is one domain of consciousness where the enactive theses seem to be less controversial, namely, bodily experiences. After drawing the agenda for an enactive view of tactile experiences, I shall highlight the difficulties that it has to face, both conceptual and empirical.
The philosophical world is indebted to Alvin Goldman for a number of reasons, and among them, his defense of the relevance of cognitive science for philosophy of mind. In Simulating minds , Goldman discusses with great care and subtlety a wide variety of experimental results related to mindreading from cognitive neuroscience, cognitive psychology, social psychology and developmental psychology. No philosopher has done more to display the resourcefulness of mental simulation. I am sympathetic with much of the general direction of Goldman’s (...) theory. I agree with him that mindreading is not a single system based on a single mechanism. And I admire his attempt to bring together the cognitive neuroscientific discovery of mirror system phenomena and the philosophical account of pretense within a unique theoretical framework of mental simulation. To do so, Goldman distinguishes two types of mindreading, respectively, based on low-level and high-level simulation. Yet, I wonder in what sense they are really two distinct processes. Here, I will confine myself largely to spelling out a series of points that take issue with the distinction between low-level and high-level mindreading. (shrink)
The golden rule of most religions assumes that the cognitive abilities of perspective-taking and empathy are the basis of morality. One would therefore predict that people that display difficulties in those abilities, such as people with psychopathy and autism, are impaired in morality. But then why do autistics have a sense of morality while psychopaths do not, given that they both display a deficit of empathy? We would like here to refine some of the views on autism and morality. In (...) order to do so, we will investigate whether autism really challenges a Humean view of morality. We will then provide a new conceptual framework based on the distinction between egocentric and allocentric stances, which may help us to make some predictions about the autistic sense of morality.

We highlight two alternative, yet complementary, solutions for harnessing available neural resources for improving integration of artificial limbs (ALs) through embodiment. ‘Hard’ embodiment exploits neural and cognitive body mechanisms by closely mimicking their original biological functions. ‘Soft’ embodiment exploits these same mechanisms by recycling them to support a different function altogether.
With 'How the body shapes the mind', Shaun Gallagher provides a general panoptic of the importance of the body in cognition, based on significant experimental results. His main goals here are (1) to describe body awareness in detail and (2) to investigate the influence of the body on self-consciousness, perception, language and social cognition. Here, I focus on two points: the distinction between the body schema and the body image and the structuring role of the body.
The brain represents the body in different ways for different purposes. Several concepts and even more numerous labels have historically been proposed to define these representations in operational terms. Recent evidence of embodiment of external objects has added complexity to an already quite intricate picture. In particular, because of their perceptual and motor effects, both rubber hands and tools can be conceived as embodied, that is, represented in the brain as if they were parts of one's own body. But are (...) there any limits to what we can embody? What constraints lay upon embodiment? And are they similar both for motor embodiment and for perceptual embodiment? Here, we consider the implications emerging from the different, and up-to-now relatively separate research domains of tool use and rubber hand illusion for understanding the rules of embodiment. In particular, we compare what the embodiment of tools and prostheses may or may not have in common. We conclude that in both cases, although for different reasons and with different constraints, embodiment is only partial. (shrink)
Performing an action and observing it activate the same internal representations of action. The representations are therefore shared between self and other. But what exactly is shared? At what level within the hierarchical structure of the motor system do SRA occur? Understanding the content of SRA is important in order to decide what theoretical work SRA can perform. In this paper, we provide some conceptual clarification by raising three main questions: are SRA semantic or pragmatic representations of action?; are SRA (...) sensory or motor representations?; are SRA representations of the action as a global unit or as a set of elementary motor components? After outlining a model of the motor hierarchy, we conclude that the best candidate for SRA is intentions in action, defined as the motor plans of the dynamic sequence of movements. We shed new light on SRA by highlighting the causal efficacy of intentions in action. This in turn explains phenomena such as inhibition of imitation. (shrink)
Here we address four objections raised by Julien Deonna, John Michael, and Francesca Fardo against a recent account of empathy for pain. First, to what extent must the empathizer share her target’s affective state? Second, how can one interpret neuroscientific findings on vicarious pain in light of recent results challenging the notion of a pain matrix? Third, can one offer a simpler account of how empathy makes one aware of another’s emotion? Finally, to what extent can this account of empathy (...) for pain be generalized to empathy for emotions?

According to Gurwitsch, the body is at least at the margin of consciousness. If all components of the field of consciousness were experienced as equally salient, we would indeed not be able to think and behave appropriately. Though the body may become the focus of our conscious field when we are introspectively aware of it, it remains most of the time only at the background of consciousness. However, we may wonder if bodily states do really need to be conscious, even (...) at the margin, or cannot be simply non-conscious. Action control requires permanent proprioceptive and visual feedback about the state and the position of our body parts. Experimental data show that action monitoring operates at a nonconscious level and we may similarly suggest that we have a continuous unconscious access to bodily information. In this chapter, I thus intend to describe the various levels of body representations with the help of Gurwitsch's distinction. I will investigate the properties and the function of each of these levels. (shrink)
On the one hand, it is often assumed that the Rubber Hand Illusion (RHI) is constrained by a structural body model so that one cannot implement supernumerary limbs. On the other hand, several recent studies reported illusory duplication of the right hand in subjects exposed to two adjacent rubber hands. The present study tested whether spatial constraints may affect the possibility of inducing the sense of ownership to two rubber hands located side by side to the left of the subject's (...) hand. We found that only the closest rubber hand appeared both objectively (proprioceptive drift) and subjectively (ownership rating) embodied. Crucially, synchronous touch of a second, but farther, rubber hand disrupted the objective measure of the RHI, but not the subjective one. We concluded that, in order to elicit a genuine RHI for multiple rubber hands, the two rubber hands must be at the same distance from the subject's hand/body. (shrink)
Motor imagery provides a direct insight into action representations. The aim of the present study was to investigate the level of impairment of action monitoring in schizophrenia by evaluating the performance of schizophrenic patients on mental rotation tasks. We raised the following questions: Are schizophrenic patients impaired in motor imagery both at the explicit and at the implicit level? Are body parts more difficult for them to mentally rotate than objects? Is there any link between the performance and the hallucinating (...) symptom profile? The schizophrenic patients displayed the same pattern of performance as the control subjects . More particularly, schizophrenic patients’ reaction time varied as a function of the angular disparity of the stimuli. On the other hand, they were significantly slower and less accurate. Interestingly, patients suffering from hallucinations made significantly more errors than non-hallucinatory patients. We discussed these latter results in terms of deficit of the forward model. We emphasized the necessity to distinguish different levels of action, more or less impaired in schizophrenia. (shrink)
Based on functional differences, Dijkerman and de Haan emphasize the duality of somatosensory processing and therefore of body representations. But how many body representations do we really have? And what kind of criterion can we use to distinguish them? I review here the empirical and conceptual difficulties in drawing such distinctions and the way to progress.
In many circumstances we tend to assume that other people believe or desire what we ourselves believe or desire. This has been labeled 'egocentric bias.' This is not to say that we systematically fail to understand other people and forget that they can have a different perspective. If it were the case, then it would be highly difficult, if not impossible, to communicate, cooperate or compete with them. In those situations, we need to take the other person's perspective and to (...) inhibit our own. But can the other's perspective furtively intrude even when no reason seems to require it, or even when it is detrimental for us? We shall see a series of evidence of what has been called altercentric bias (Samson et al., 2010; Apperly, 2011): other people's beliefs can unduly influence us even when they are wrong. At first sight, altercentric bias questions 1st person priority. In particular, it may appear as incompatible with simulation-based accounts of 3rd person mindreading. We shall argue, on the contrary, that the simulationist framework enables confusions between self and others that go both ways: taking one's beliefs for the other's beliefs (egocentric bias) and vice-versa, taking the other's beliefs for one's beliefs (altercentric bias). We shall then see how the risk of such confusion may be disadvantageous from an evolutionary perspective, questioning thus the evolutionary plausibility of the simulation theory. (shrink)
In this paper, I give an account of a hitherto neglected kind of ‘here’, which does not work as an intentional indexical. Instead, it automatically refers to the immediate perceptual environment of the subject’s body, which is known as peripersonal space. In between the self and the external world, there is something like a buffer zone, a place in which objects and events have a unique immediate significance for the subject because they may soon be in contact with her. I (...) argue that seeing objects as being here in a minimal sense means seeing them in the place in which the perceptual system expects the world and the body to collide. I further argue that this minimal notion of here-content gives rise to a tactile sense of presence. It provides a unique experiential access to the reality of the seen object by making us aware of its ability to have an effect on us. (shrink)
The classic notion of an egocentric frame of reference cannot be easily applied to bodily space, given the difficulties in providing a centre of such frame as well as axes on which one could compute distances and directions . Yet, Smith tries to rehabilitate the egocentric account of bodily frame by switching from an anatomical definition of egocentricity to a more functional definition . Here I will review some empirical evidence that shows that one cannot ground bodily experiences in action. (...) There is more than one type of bodily spatial representations, and only one of them is linked to actions. How then to account for bodily spatial content? What is encoded in the spatial content and how? I will provide a tentative account based on two types of spatial content, namely, coordinate body space and categorical body space. (shrink)
According to a motor theory of empathy, empathy results from the automatic activation of emotion triggered by the observation of someone else's emotion. It has been found that the subjective experience of emotions and the observation of someone else experiencing the same emotion activate overlapping brain areas. These shared representations of emotions could be the key for the understanding of empathy. However, if the automatic activation of SRE suffi ces to induce empathy, we would be in a permanent emotional turmoil. (...) In contrast, it seems intuitively that we do not empathize all the time and that far from being automatic, empathy should be explained by a complex set of cognitive and motivational factors. I will provide here a new account of the automaticity of empathy, starting from a very simple question: when do we empathize? We need to distinguish clearly the activation of SRE and empathy. I will provide a model that accounts both for the automaticity of the activation of SRE and for the selectiveness of empathy. As Prinz says about imitation, the problem is not so much to account for the ubiquitous occurrence of empathy, but rather for its notorious nonoccurrence in many situations. (shrink)

According to a traditional Cartesian view of the mind, you have a privileged access to your own conscious experiences that nobody else can have. Therefore, you have more authority than anybody else on your own experiences. Perceptual experiences are selfintimating: you are aware of what you are consciously perceiving. If you report seeing a pink elephant, nobody is entitled to deny it. There may be no pink elephant, but you do have the conscious experience of such elephant. However, the progress (...) in brain imaging might lead to the possibility that the scientist knows as well as you – or even better than you – what you are seeing, and even what you are hallucinating. What was only a thought experiment fourty years ago has become reality. Does brain reading challenge the privacy of the mind? Who has the most authority on your mind in case of conflict? You or the brain scientist? (shrink)
Research into peripersonal space has yielded exciting discoveries across many fields, from anthropology to cognitive neuroscience. Bringing these perspectives together for the first time, The World at Our Fingertips presents a fresh, accessible dialogue, challenging entrenched ideas about the way people see and understand the world around them.
The body may be the object we know the best. It is the only object from which we constantly receive a flow of information through sight and touch; and it is the only object we can experience from the inside, through our proprioceptive, vestibular, and visceral senses. Yet there have been very few books that have attempted to consolidate our understanding of the body as it figures in our experience and self-awareness. This volume offers an interdisciplinary and comprehensive treatment of (...) bodily self-awareness, the first book to do so since the landmark 1995 collection The Body and the Self, edited by José Bermúdez, Naomi Eilan, and Anthony Marcel. Since 1995, the study of the body in such psychological disciplines as cognitive psychology, cognitive neuroscience, psychiatry, and neuropsychology has advanced dramatically, accompanied by a resurgence of philosophical interest in the significance of the body in our mental life. The sixteen specially commissioned essays in this book reflect the advances in these fields. The book is divided into three parts, each part covering a topic central to an explanation of bodily self-awareness: representation of the body; the sense of bodily ownership; and representation of the self.

Can concepts represent subtleties in emotions, bodily sensations, and perceptions? What is the nature of mental representations in nonlinguistic and prelinguistic creatures? _The European Review of Philosophy, Volume 6_ tackles issues such as these by asking how far the analogy between conceptual and nonconceptual content can be carried. By bringing together contributions from both conceptualists and nonconceptualists, this volume sheds new light on an issue sure to interest cognitive scientists and philosophers of mind.
Hysteria has been the subject of controversy for many years, with theorists arguing about whether it is best explained by a hidden organic cause or by malingering and deception. However, it has been shown that hysterical paralysis cannot be explained in any of these terms. With the recent development of cognitive psychiatry, one may understand psychiatric and organic delusions within the same conceptual framework. Here I contrast hysterical conversion with anosognosia. They are indeed remarkably similar, though the content of their (...) respective delusions is the opposite. In hysterical paralysis, patients are not aware of their preserved ability, whereas in anosognosia for hemiplegia, patients are not aware of their disability. Four main explanations have been provided to account for anosognosia: metacognitive, attentional, motor, and motivational views. I will apply each of these accounts to hysterical paralysis and show that, at each level, hysterical conversion is the reverse of anosognosia. I will suggest that hysterical paralysis results from the interaction between attentional somatosensory amplification and affective inhibition of action. (shrink)
L’hystérie se définit comme un déficit fonctionnel sans cause organique. Par exemple, certains patients sont incapables de se mouvoir volontairement, comme s’ils étaient véritablement paralysés, sans que l’on puisse fournir une explication physiologique. À l’inverse, les patients souffrant d’anosognosie sont véritablement paralysés, mais affirment pouvoir bouger. Ces pathologies résultent toutes deux d’un trouble de la conscience de la capacité à agir : les uns croient qu’ils ne peuvent pas agir alors qu’ils le pourraient et les autres croient pouvoir agir alors (...) qu’ils en sont incapables. Mais de quoi dépend cette forme spécifique de conscience ? En comparant ces deux syndromes miroirs, je chercherai à révéler les processus mis en jeu par la conscience de la capacité à agir et à jeter un jour nouveau sur l’hystérie. S’agit-il d’un trouble de la volonté, et si oui, à quel niveau se produit-il ? J’analyserai ainsi les relations respectives entre la conscience de la capacité d’agir et la conscience d’agir, et montrerai le rôle joué par l’image corporelle. (shrink)
What are the epistemic bases of the knowledge of the reality of our own body? Proprioception plays a primordial role in body representation and more particularly at the level of body schema. Without proprioception people can feel amputated and the mislocalization of proprioceptive information through the remapping of the Penfield Homonculus induces illusions of phantom limbs, illusions that contradictory visual feedback cannot erase. However, it turns out that it is not as simple as that and that vision also intervenes in (...) body knowledge: vision of one's own body allows deafferented patients to move and phantom limbs to disappear. Finally, the existence of phantom limbs in aplasic patients as well as studies on neonates provide evidence of an innate component of body representation. (shrink)
