This paper examines the experience of where we end and the rest of the world begins, that is, the sense of boundaries. Since meditators are recognized for their ability to introspect about the bodily level of experience, and in particular about their sense of boundaries, 27 senior meditators were interviewed for this study. The main conclusions of this paper are that the boundaries of the so-called “physical body” are not equivalent to the individual's sense of boundaries; the sense of boundaries (...) depends upon sensory activity; the sense of boundaries should be defined according to its level of flexibility; the sense of body ownership cannot be reduced to the sense of boundaries; nevertheless, the sense of ownership depends on the level of flexibility of the sense of boundaries.

Based on interviews with more than 70 survivors of traumatic events, Ataria presents a trade-off model between the sense of agency—the feeling that one has a sense of control over one’s actions—and the sense of body ownership, the sense that this is my body. According to this trade-off model, there exists a reciprocal relationship between the sense of agency and sense of body ownership: by relinquishing a degree of the sense of body ownership over his body, the subject gains an (...) sense of agency. Essentially, this trade-off enables the traumatized subject to maintain a limited sense of control during acute... (shrink)

This paper seeks to describe and analyze the traumatic experience through an examination of the sense of agency—the sense of controlling one’s body, and sense of ownership—the sense that it is my body that undergoes experiences. It appears that there exist two levels of traumatic experience: on the first level one loses the sense of agency but retains the sense of ownership, whilst on the second one loses both of these, with symptoms becoming progressively more severe. A comparison of the (...) traumatic experience with various modulations of the senses of agency and ownership, from cases involving prostheses to tools requiring greater or lesser extents of control, suggests that the harsher the traumatic event, the greater the damage is to the sense of ownership, resulting in the increasing sense of the body as a tool rather than an original organism. Likewise, the long-term ramifications become more severe according to the significance of the damage to the sense of ownership. (shrink)

This paper suggests that during severe and prolonged traumatic experiences such as trauma type II, one may develop disownership toward the entire body. In this situation one’s body becomes a pure object and as such an integral part of the hostile environment. This article applies Merleau-Ponty’s approach to perception in order to improve our understanding of this process.

Dissociation during trauma lacks an adequate definition. Using data obtained from interviews with 36 posttraumatic individuals conducted according to the phenomenological approach, this paper seeks to improve our understanding of this phenomenon. In particular, it suggesting a trade off model depicting the balance between the sense of agency and the sense of ownership : a reciprocal relationship appears to exist between these two, and in order to enable control of the body during trauma the sense of ownership must decrease. When (...) the relationship between the sense of agency and sense of ownership changes disproportionately to the constraints of the traumatic event, the dissociative mechanism becomes dysfunctional. By contrast, when the relations alter in accordance with the surrounding conditions, the dissociative mechanism functions properly. (shrink)

War captivity is an extreme traumatic experience typically involving exposure to repeated stressors, including torture, isolation, and humiliation. Captives are flung from their previous known world into an unfamiliar reality in which their state of consciousness may undergo significant change. In the present study extensive interviews were conducted with fifteen Israeli former prisoners of war who fell captive during the 1973 Yom Kippur war with the goal of examining the architecture of human thought in subjects lacking a sense of body (...) (disembodiment) as a result of confinement and isolation. Analysis of the interviews revealed that threats to a normal sense of body often lead to a loss of the sense of time as an objective dimension. Evidence suggests that the loss of the sense of body and the loss of the sense of time are in fact connected; that is, they collapse together. This breakdown in turn results in a collapse of the sense of self. (shrink)

We challenge Gallagher’s distinction between the sense of ownership (SO) and the sense of agency (SA) as two separable modalities of experience of the minimal self and argue that a careful investigation of the examples provided to promote this distinction in fact reveals that SO and SA are intimately related and modulate each other. We propose a way to differentiate between the various notions of SO and SA that are currently used interchangeably in the debate, and suggest a more gradual (...) reading of the two that allows for various blends of SO and SA. Such an approach not only provides us with a richer phenomenology but also with a more parsimonious view of the minimal self. (shrink)

This paper addresses the nature of touch or ?tactual perception?. I argue that touch encompasses a wide range of perceptual achievements, that treating it as a number of separate senses will not work, and that the permissive conception we are left with is so permissive that it is unclear how touch might be distinguished from the other senses. I conclude that no criteria will succeed in individuating touch. Although I do not rule out the possibility that this also applies to (...) other senses, I suggest that the heterogeneity of touch makes it both distinctive and particularly problematic. (shrink)

This paper explores the phenomenology of touch and proposes that the structure of touch serves to cast light on the more general way in which we 'find ourselves in a world'. Recent philosophical work on perception tends to emphasize vision. This, I suggest, motivates the imposition of a distinction between externally directed perception of objects and internally directed perception of one's own body. In contrast, the phenomenology of touch involves neither firm boundaries between body and world nor perception of bodily (...) states in isolation from perception of everything else. I begin by arguing that touch does not involve two distinct feelings, a feeling of the body and a feeling of something external to the body. Rather, these are inextricable aspects of the same unitary experience, with one or the other occupying the experiential foreground. Then I suggest that tactile experience does not always respect a clear boundary between body and world. In touch, bodily and worldly aspects are experienced in a number of different ways and, in many instances, there is no clear experiential differentiation between the two. Finally, I draw these two points together in order to consider the contribution made by touch to our sense of being situated in a world. (shrink)

This article presents an interview method which enables us to bring a person, who may not even have been trained, to become aware of his or her subjective experience, and describe it with great precision. It is focused on the difficulties of becoming aware of one’s subjective experience and describing it, and on the processes used by this interview technique to overcome each of these difficulties. The article ends with a discussion of the criteria governing the validity of the descriptions (...) obtained, and then with a brief review of the functions of these descriptions. (shrink)

The well-known experiments of Nisbett and Wilson lead to the conclusion that we have no introspective access to our decision-making processes. Johansson et al. have recently developed an original protocol consisting in manipulating covertly the relationship between the subjects’ intended choice and the outcome they were presented with: in 79.6% of cases, they do not detect the manipulation and provide an explanation of the choice they did not make, confirming the findings of Nisbett and Wilson. We have reproduced this protocol, (...) while introducing for some choices an expert guidance to the description of this choice. The subjects who were assisted detected the manipulation in 80% of cases. Our experiment confirms Nisbett and Wilson’s findings that we are usually unaware of our decision processes, but goes further by showing that we can access them through specific mental acts.

A review of several theories and brain-imaging experiments shows that there is no consensus about how to define the sense of agency. In some cases the sense of agency is construed in terms of bodily movement or motor control, in others it is linked to the intentional aspect of action. For some theorists it is the product of higher-order cognitive processes, for others it is a feature of first-order phenomenal experience. In this article I propose a multiple aspects account of (...) the sense of agency. (shrink)

Muselmannwas a term used in German concentration camps to describe prisoners near death due to exhaustion, starvation, and helplessness. This paper suggests that the inhuman conditions in the concentration camps resulted in the development of a defensive sense of disownership toward the entire body. The body, in such cases, is reduced to a pure object. However, in the case of theMuselmannthis body-as-object is felt to belong to the captors, and as such is therefore identified as a tool to inflict suffering (...) and pain on theMuselmannhimself. In this situation, lacking cognitive resources, theMuselmannmay have no other alternative than to treat his body as an enemy, and then to retreat or disinvest from the body. This response is a form of somatic apathy, an indifference that is tied to a loss of the self/non-self distinction. This may, in turn, lead to suicidal inclinations, even after liberation from the camp. (shrink)

Although philosophical approaches to the self are diverse, several of them are relevant to cognitive science. First, the notion of a 'minimal self', a self devoid of temporal extension, is clarified by distinguishing between a sense of agency and a sense of ownership for action. To the extent that these senses are subject to failure in pathologies like schizophrenia, a neuropsychological model of schizophrenia may help to clarify the nature of the minimal self and its neurological underpinnings. Second, there is (...) good evidence to suggest that although certain aspects of the minimal self are primitive and embodied, other aspects may be accessed only in reflective consciousness. Employing a modified concept of the minimal self, it may be possible to construct a robotic form of non-conscious self-reference that depends on an interaction between the robotic body and its environment. In contrast to the minimal self, the narrative self involves continuity over time and is directly relevant to discussions of memory and personal identity. There is growing consensus among philosophers and cognitive scientists about the importance of narrative and its relation to episodic memory and left-hemisphere functions. There are, however, at least two different views of how the narrative self is structured. On one model it is nothing more than an abstract point. On a more extended view, proposed here, the self is a rich amalgam of narratives that allows for the equivocations, contradictions, and self-deceptions of personal life. Even in this case, however, neurocognitive models contribute to our understanding of how narrative identity is structured. (shrink)

We review the use of introspective and phenomenological methods in experimental settings. We distinguish different senses of introspection, and further distinguish phenomenological method from introspectionist approaches. Two ways of using phenomenology in experimental procedures are identified: first, the neurophenomenological method, proposed by Varela, involves the training of experimental subjects. This approach has been directly and productively incorporated into the protocol of experiments on perception. A second approach may have wider application and does not involve training experimental subjects in phenomenological method. (...) It requires front-loading phenomenological insights into experimental design. A number of experiments employing this approach are reviewed. We conclude with a discussion of the implications for both the cognitive sciences and phenomenology. (shrink)

How do I know that I am the person who is moving? According to Wittgenstein (1958), 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 (Georgieff & Jeannerod, 1998) which is disrupted in delusions of (...) control (Frith, 1992). 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)

This paper responds to the issues raised by D. Chalmers by offering a research direction which is quite radical because of the way in which methodological principles are linked to scientific studies of consciousness. Neuro-phenomenology is the name I use here to designate a quest to marry modern cognitive science and a disciplined approach to human experience, thereby placing myself in the lineage of the continental tradition of Phenomenology. My claim is that the so-called hard problem that animates these Special (...) Issues can only be addressed productively by gathering a research community armed with new pragmatic tools for the development of a science of consciousness. I will claim that no piecemeal empirical correlates, nor purely theoretical principles, will really help us at this stage. We need to turn to a systematic exploration of the only link between mind and consciousness that seems both obvious and natural: the structure of human experience itself. In what follows I motivate my choice by briefly examining the current debate about consciousness at the light of Chalmer’s hard problem. Next, I outline the phenomenological strategy. Finally I conclude by discussing some of the main difficulties and consequences of this strategy. (shrink)

The main objective of this article is to capitalise on many years of research, and of practice, relating to the use of introspection in a research context, and thus to provide an initial outline description of introspection, while developing an introspection of introspection. After a description of the context of this research, I define the institutional conditions which would enable the renewal of introspection as a research methodology. Then I describe three aspects of introspective practice: 1) introspection as a process (...) of becoming aware, theorized through Husserl's model of consciousness modes; 2) introspection as recollection, through the model of retention and awakening in Husserl's theory of memory; 3) the use of universal descriptive categories for the description of all lived experiences, as a guide for skilled practice of introspection in research. Finally I examine the question of the validation of introspective data, suggesting a strong distinction between the ethical criterion and the epistemic criterion of truth. (shrink)
