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)

Open peer commentary on the article “The Plasticity of the Bodily Self: Head Movements in Bodily Illusions and Their Relation to Gallagher’s Body Image and Body Schema” by Marte Roel Lesur, Michael Gaebler, Philippe Bertrand & Bigna Lenggenhager.: In my commentary, I raise some questions about the applicability of Gallagher’s distinction between body image and body schema to the experimental research reported and discussed in the target article. I suggest that the distinction between body image and body schema is of (...) limited help in this context, and that Gallagher’s distinction between sense of ownership and sense of agency provides a more natural and fruitful theoretical framework to discuss that research.

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.

I introduce and defend the notion of a cognitive account of the sense of ownership. A cognitive account of the sense of ownership holds that one experiences something as one's own only if one thinks of something as one's own. By contrast, a phenomenal account of the sense of ownership holds that one can experience something as one's own without thinking about anything as one's own. I argue that we have no reason to favour (...) phenomenal accounts over cognitive accounts, that cognitive accounts are plausible given that much of our mental activity has unnoticed effects on our mental life, and that certain illusory experiences of body ownership sometimes described as thought-independent may be best explained as imaginative perceptual experiences.

Depersonalization consists in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, and his mind, and even from himself. Even though, when it was discovered at the end of the 19th century, this psychiatric condition was widely used to probe certain aspects of bodily awareness, and more specifically the sense of bodily ownership (SBO), it has been strangely neglected in contemporary debates. In this chapter, (...) I argue that because of three specific features, depersonalization raises some important challenges for current theories of the SBO. The first feature — call it “generality” — is that depersonalization does not only affect the sense of bodily ownership but also, typically, the sense of ``mental ownership’’ (SMO), the sense of agency or ``action ownership’’ (SOA), and the subject’s core sense of herself (CSS), that is, her awareness of herself as an I. The second feature is that except for the symptoms of depersonalization, depersonalized patients are hard to distinguish, psychologically, from normal subjects. This makes it hard to find psychological features that might explain their condition. The last feature, call it “fundamentality” is that the psychological features that do seem abnormal among depersonalized patients seem more likely to be explained by depersonalization than to explain it. These three features raise three challenges — the centrality challenge, the dissociation challenge, and the grounding challenge. Taken together, I will argue, these challenges suggest that the SBO depends on a form of phenomenal “mineness” that would mark my mental states as mine and that cannot be accounted for in sensorimotor, cognitive, or even affective terms. A phenomenal mineness that indeed seems to be psychologically primitive, and only accountable in neurophysiological terms. (shrink)

There are non-governmental organizations that operate transnationally and there are those that operate within the boundaries of a nation. A third use of non-governmental organizations is articulated. We may call this third category an instrumental use of non-governmental organizations to facilitate the transfer of the work of third-party conflict resolution practitioners to the two previously feuding parties. Representative accounts are provided in Part I of this paper. In Part II, the instrumental use of the NGO to transfer knowledge from practitioners (...) to the indigenous and previously feuding parties is depicted as a means to fill a practice gap in the field of conflict resolution, where many praxes do not examine the transfer of knowledge in an experiential and discovery-oriented way. An alternative is presented where the process of appropriation is suggested as an object of study. In Part III, a conceptualization of how one may determine the phenomenology of a sense of ownership of the project by the previously feuding parties is provided. A phenomenological account of the journey from constituting subjectivity to a constituted objectivity is articulated to the point where we see a division of labour between Husserl’s transcendental project, that seeks universal and broader essences, and psychology, which is highly contextualized. Part IV constitutes the implementation of the praxis to answer the specific question, “What is the sense of ownership of the parties in conflict?” - and, derivatively, “What is the fate of the hitherto agonistic relation?” A conflict resolution model is consolidated or reconfigured using the lessons drawn from the results of the study and from a second look at the literature to see where changes in practice and reconceptualization may be required.

The experience of one’s body as one’s own is normally referred to as one’s “bodily sense of ownership” (BSO). Despite its centrality and importance in our lives, BSO is highly elusive and complex. Different psychopathologies demonstrate that a BSO is unnecessary and that it is possible to develop a limited BSO that extends beyond the borders of one’s biological body. Therefore, it is worth asking: what grounds one’s BSO? The purpose of this paper is to sketch a preliminary (...) answer to the ‘grounding question.’ Thus, I begin by briefly presenting some contemporary competing hypotheses concerning the ‘grounding question’ and explain why they seem unsatisfying. Second, I discuss the “dual-aspect” of bodily awareness, which is manifest in every normal tactile experience and consists in a subject-object structure of awareness. I then argue that the “dual-aspect” of bodily awareness has the potential of explaining BSO and can, therefore, be considered its grounds. Taking the “dual-aspect” of bodily awareness as the grounds of BSO manages to escape difficulties faced by contemporary hypotheses concerning BSO, fulfills certain necessary demands upon any account of BSO, and explains relevant empirical findings and psychopathologies. Consequently, I argue that it is a hypothesis worth pursuing. (shrink)

Both evolutionary and developmental research indicate that humans are adapted to respecting property rights, independently (and possibly orthogonally) of considerations of fairness. We offer evidence from psychological experiments suggesting that enforcing one's rights and respecting others' possessions are basic cognitive mechanisms automatically activated and grounded in humans' sensory-motor system. This may entail an independent motivation that is more profound than considerations of fairness and impartiality.

This article examines the inflationary view of the body ownership. It reviews a growing body of empirical research on the sense of body ownership that suggests that the deflationary depends on the integration of somatosensory signals. It discusses the results of recent research on out-of-body experiences and shows that the neurocognitive processes involved in the Rubber Hand Illusion are also involved in OBE. It suggests that this experience of bodily ownership may be a critical component of (...) self-specificity. (shrink)

Pascal Boyer achieves a felicitous integration of what is known about human ownership psychology by deriving ownership intuitions from the interaction of resource acquisition and our cooperative sociality. By exploring the sense of ownership already present in the domain of resource acquisition, I sketch an evolutionary path to the open-ended nature of the specifically human version of that sense.

In this insightful and well-argued article, Osler aims to provide a more fine-grained, phenomenological account of anorectic bodily experience. She notes that although anorexia nervosa often is understood in terms of a distorted body image, this approach does not exhaustively or accurately reflect many subjects' bodily experiences, and also unduly privileges a third-person perspective over first-person accounts. In addition, focusing primarily on body image gives rise to the impression that AN is a form of radical dieting gone wrong as a (...) result of misperceiving or misjudging one's body size or shape. Osler emphasizes that AN is not a static disorder, but rather involves numerous stages. To account for the... (shrink)

We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the elderly an increased (...) improvement after a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

About 75% of subjects diagnosed with schizophrenia experience auditory-verbal hallucination and report "hearing voices" that are not actually present. One notable feature of AVH is that it seems involuntary and not directly in the subject's control. With regard to content, these represented voices make utterances, typically commands and evaluations, and either are directed to the patient or speak about her in the third person. Voices may echo the subject's thoughts or comment on the subject's behavior and, in some cases, the (...) voices seem to carry on conversations or even argue. Subjects often experience the voices as having pitch, timbre, and intensity, and as having a... (shrink)

We challenge Gallagher’s distinction between the sense of ownership and the sense of agency 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)

How does Descartes characterize the peculiar way in which each of us is aware of our bodies? I argue that Descartes recognizes a sense of bodily ownership, such that the body sensorily appears to be one's own in bodily awareness. This sensory appearance of ownership is ubiquitous, for Descartes, in that bodily awareness always confers a sense of ownership. This appearance is confused, in so far as bodily awareness simultaneously represents the subject as identical to, (...) partially composed by, and united to her body, without distinguishing these relations. Finally, the appearance of ownership is grounded in multiple other ways in which the body sensorily appears: namely, in the fact that the body appears to be inescapable, modified by bodily sensations, and an object of special concern.

There are two ways in which we are aware of our bodies: reflectively, when we attend to them, and pre-reflectively, a kind of marginal awareness that pervades regular experience. However, there is an inherent issue with studying bodily awareness of the pre-reflective kind: given that it is, by definition, non-observational, how can we observe it? Kuhle claims to have found a way around this problem—we can study it indirectly by investigating an aspect of reflective bodily awareness: the sense of (...) bodily ownership. Unfortunately, I argue, there is little reason to believe a relationship between pre-reflective bodily awareness and the sense of bodily ownership exists. Until more work is done, pre-reflective bodily awareness remains beyond our empirical grasp. (shrink)

Emerging evidence is now challenging the view that patients diagnosed with schizophrenia experience a selective deficit in their sense of agency. Additional disturbances seem to exist in their sense of body ownership. However, the factors underlying this disturbance in body ownership remain elusive. Knowledge of these factors, and increased understanding of how body ownership is related to other abnormalities seen in schizophrenia, could ultimately advance development of new treatments. Research on body ownership in schizophrenia (...) has mainly been investigated with the rubber hand illusion (RHI). Schizophrenia patients show higher susceptibility to the RHI, which may be explained by a stronger reliance on multisensory information over weaker stored body representations. This review shows that a coherent sense of body ownership arises from the integration of both bottom-up sensory processes and higher order, top-down bodily- and perceptual representations. Multisensory integration, temporal binding, anticipation, intention and efferent signals all partly modulate the complex experience of body ownership. Specifically, we propose that patients with schizophrenia have weaker stored body representations, and rely to a greater extent on external stimuli, such as visual information, due to imprecise or highly variable internal predictions on the consequences of action. Moreover, the reduced sense of agency in schizophrenia may additionally contribute to the disturbed sense of body ownership, as evidence from healthy participants suggests that agency and body ownership are interrelated. Vice versa, a reduced sense of body ownership may also contribute to a reduced sense of agency. Future studies should explicitly target the precise relation between the two in schizophrenia.

Multisensory stimulation has been shown to alter the sense of body-ownership. Given that perceived similarity between one’s own body and those of others is crucial for social cognition, we investigated whether multisensory stimulation can lead participants to experience ownership over a hand of different skin colour. Results from two studies using introspective, behavioural and physiological methods show that, following synchronous visuotactile stimulation, participants can experience body-ownership over hands that seem to belong to a different racial group. (...) Interestingly, a baseline measure of implicit racial bias did not predict whether participants would experience the RHI, but the overall strength of experienced body-ownership seemed to predict the participants’ post-illusion implicit racial bias with those who experienced a stronger RHI showing a lower bias. These findings suggest that multisensory experiences can override strict ingroup/outgroup distinctions based on skin colour and point to a key role for sensory processing in social cognition.

To what extent do I have a sense of agency over my thoughts while I dream? The sense of agency in dreams can alter in a variety of interesting ways distinct from normal, waking experience. In fact, dreams show many similarities to the experiences of individuals with schizophrenia. In this paper I analyze these alterations with a focus on distinguishing between reduced sense of agency and other cognitive features such as metacognition, confabulation and attention. I argue that (...) some dream reports demonstrate two interesting commonalities with schizophrenia: thought insertion (TI) and auditory hallucination (AH). This line of research has the potential to further our understanding of TI and AH in schizophrenia through the analysis of similar experience in a different conscious state. Through the analysis of dream reports, I found that although TI and AH both occur in dreams, TI is very rare. This is an interesting result since TI is common in patients with schizophrenia. I propose two speculative lines of explanation for the rarity of TI in dreams: first, the cognitive differences between the symptoms of schizophrenia and dreams, and second, the problem of dream reporting conditions. Dream reporting conditions are particularly important, as without controls, reports can be vague. Analysis of dream reports reveals that it is often unclear whether 'hearing voices' indicates sound phenomenology or thought phenomenology. I propose that dream reports could be disambiguated given the right experimental conditions and I suggest how this could be achieved in future experimental research. (shrink)

Bodily sensations are mental states typically suitable to be reported in judgments in which a first-person indexical is used to qualify the felt body. In other words, subjects typically have a sense of bodily ownership for the body that they feel in bodily sensations. This paper puts forward, firstly, three desiderata that theories on the sense of bodily ownership should meet. Secondly, it assesses two views that account for the sense of bodily ownership in (...) terms of the spatial content of bodily sensations, appealing to a notion of a sense of boundedness, and argues that they do not meet the goals defined.

ABSTRACT There has been much discussion about the sense of ownership recently. It is a very controversial topic and even minimal consensus seems hard to achieve. In this paper we attempt to assess the prospects of achieving a better understanding of what is meant by 'sense of body ownership'. In order to do so, we begin by addressing an objection on which the notion itself might depend, coming from the distinction between 'inflationary' and 'deflationary' accounts of (...) the sense of body ownership. Once the path is clear, we will consider some influential ways of approaching the issue, which propose grounding the sense of ownership in the spatiality of bodily sensations, the affective dimension of bodily experience, and in its spatial dimension, among other things. We expect the results of our discussion will allow us to both identify the strongest candidates for an account of the sense of body ownership and to determine the challenges that must be met by competing explanations. RESUMEN Recientemente se ha discutido mucho sobre el sentido de propiedad. Se trata de un tema muy controversial, en el que incluso consensos mínimos parecen difíciles de alcanzar. En este artículo intentamos abordar las perspectivas que existen de lograr una mejor comprensión de lo que significa "sentido de propiedad del cuerpo". Para tal fin, empezamos abordando una objeción de la que podría depender la noción misma, derivada de la distinción entre explicaciones 'inflacionarias' y 'deflacionarias' del sentido de propiedad del cuerpo. Una vez se haya despejado el camino, consideraremos algunas aproximaciones reconocidas al asunto, las cuales proponen fundamentar el sentido de propiedad en la espacialidad de las sensaciones corporales, en la dimensión afectiva de la experiencia corporal, en su dimensión espacial, entre otras. Esperamos que los resultados de nuestra discusión nos permitan al mismo tiempo identificar los candidatos más fuertes para explicar el sentido de propiedad del cuerpo y determinar los retos que deben enfrentar las explicaciones en contienda.

What does it take for a subject to experience a personal memory as being her own? According to Fernández’ (2019) model of endorsement, this particular phenomenal quality of our memories, their “sense of mineness”, can be explained in terms of the experience of the mnemonic content as veridical. In this article, I criticize this model for two reasons: (a) the evidence that is used by Fernández to ground his theoretical proposal is dubious; and more importantly, (b) the endorsement model (...) does not accommodate many non-pathological everyday memories that preserve their sense of mineness, but whose veridicality is explicitly denied, suspected, not automatically endorsed, or neither denied nor endorsed. Finally, I sketch two alternative explanations: one also problematic, the other one more promising, and present some normative advantages of the latter. This also displays the undesirability of the endorsement model from a normative perspective. (shrink)

The standard approach to the core phenomenology of thought insertion characterizes it in terms of a normal sense of thought ownership coupled with an abnormal sense of thought agency. Recently, Fernández (2010) has argued that there are crucial problems with this approach and has proposed instead that what goes wrong fundamentally in such a phenomenology is a sense of thought commitment, characterized in terms of thought endorsement. In this paper, we argue that even though Fernández raises (...) new issues that enrich the topic, his proposal cannot rival the version of the standard approach we shall defend. (shrink)

I focus on the sense of ownership and ask whether this experience is some­thing over and above one’s bodily experiences, or something intrinsic to them. I consider liberal, deflationary, and phenomenological accounts of the sense of ownership, and I offer an enactive or action-oriented account that takes the sense of ownership to be intrinsic to the phenomenal background and our various bodily senses, including the sense of agency.

The psychology of ownership is rooted in self-ownership. The human brain has an evolved interoceptive sense of owning the body that supports self-ownership and the ownership of external things as extensions of the self-owning self. In this way, evolutionary neuroscience supports a Lockean liberal conception of equal natural rights rooted in natural self-ownership.

The Abhidharma Buddhist revisionary metaphysics aims to provide an intellectually and morally preferred picture of the world that lacks a self. The first part of the paper claims that the Abhidharma ‘no-self’ view can be plausibly interpreted as a no-ownership view, according to which there is no locus or subject of experience and thus no owner of mental or bodily awarenesses. On this interpretation of the no-self view, the Abhidharma Buddhist metaphysicians are committed to denying the ownership of (...) experiences, and thereby apparently obliged to explain our purported experience of ownership. My experiences seemingly come with the sense that I am the one who is undergoing this experience. But is there a really an experience of ownership—namely, an experience of being a subject that underlies our sense of ownership? I argue that there is nothing that it is like to be an owner of experiences, in the sense that there is no experiential phenomenology associated with the ownership of experience. The second part of the paper argues that, since there is no experience of ownership, there is no onus on the Abhidharma philosopher to give an explanation of the sense of ownership. (shrink)

In this work we analyse the main interpretations of ownership in Original Institutional Economics (OIE) and their links with pragmatist psychology and psychoanalysis. We consider Thorstein Veblen's notion of ownership as a relation of possession of persons, and John R.Commons's distinction between “corporeal” and “intangible” property, that marks the shift from a material possession of goods and arbitrary power over the workers to the development of human faculties in a more participatory environment. For space reasons we do not (...) address other contributions developed both by the OIE and by the New Institutional Economics. We then consider a number of contributions of pragmatist social psychology and psychoanalysis that, although not dealing directly with the notion of ownership, can cast light not only on the private and “material“ aspects of ownership but also on its collective and “relational aspects”. The reason why we consider it useful to address different perspectives is that, as observed by the famous sociologist Karl Mannheim (1952), a landscape can be seen only from a determined perspective and without perspective there is no landscape. Hence, observing a landscape (or phenomenon) from different angles (or disciplines) can help to acquire a much clearer insight into the features of the various perspectives. And this is one of the main advantage of a pluralist approach to the study of economic and social phenomena, also aimed at overcoming the fragmentation so often present in social sciences. In this light, the interpretative theories that we address, however different in many respects, present notable complementarities, in the sense that the aspects more overlooked by some are more completely considered by the others. In our work, these different but complementary notions of ownership can help illuminate the manifold aspects of human relations, also with a view to provide a more tailored policy action for the solution of their more problematic aspects.

Self-location—the sense of where I am in space—provides an experiential anchor for one's interaction with the environment. In the studies of full-body illusions, many researchers have defined self-location solely in terms of body-location—the subjective feeling of where my body is. Although this view is useful, there is an issue regarding whether it can fully accommodate the role of 1PP-location—the sense of where my first-person perspective is located in space. In this study, we investigate self-location by comparing body-location and (...) 1PP-location: using a head-mounted display (HMD) and a stereo camera, the subjects watched their own body standing in front of them and received tactile stimulations. We manipulated their senses of body-location and 1PP-location in three different conditions: the participants standing still (Basic condition), asking them to move forward (Walking condition), and swiftly moving the stereo camera away from their body (Visual condition). In the Walking condition, the participants watched their body moving away from their 1PP. In the Visual condition, the scene seen via the HMD was systematically receding. Our data show that, under different manipulations of movement, the spatial unity between 1PP-location and body-location can be temporarily interrupted. Interestingly, we also observed a “double-body effect.” We further suggest that it is better to consider body-location and 1PP-location as interrelated but distinct factors that jointly support the sense of self-location.

The rubber hand illusion is one of the most commonly used paradigms to examine the sense of body ownership. Touches are synchronously applied to the real hand, hidden from view, and a false hand in an anatomically congruent position. During the illusion one may perceive that the feeling of touch arises from the false hand, and that the false hand is one's own. The relationship between referral of touch and body ownership in the illusion is unclear, and (...) some articles average responses to statements addressing these experiences, which may be inappropriate depending on the research question of interest. To address these concerns, we re-analyzed three freely available datasets to better understand the relationship between referral of touch and feeling of ownership in the RHI. We found that most participants who report a feeling of ownership also report referral of touch, and that referral of touch and ownership show a moderately strong positive relationship that was highly replicable. In addition, referral of touch tends to be reported more strongly and more frequently than the feeling of ownership over the hand. The former observations confirm that referral of touch and ownership are related experiences in the RHI. The latter, however, indicate that when pooling the statements one may obtain a higher number of illusion ‘responders’ compared to considering the ownership statements in isolation. These results have implications for the RHI as an experimental paradigm. (shrink)

De Vignemont argues that the sense of ownership comes from the localization of bodily sensation on a map of the body that is part of the body schema. This model should be taken as a model of the sense of embodiment. I argue that the body schema lacks the theoretical resources needed to explain this phenomenology. Furthermore, there is some reason to think that a deficient sense of embodiment is not associated with a deficient body schema. (...) The data de Vignemont uses to argue that the body image does not underlie the sense of embodiment does not rule out the possibility that part of the body image I call 'offline representations' underlies the sense of embodiment. An alternative model of the sense of embodiment in terms of offline representations of the body is presented. (shrink)

We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a fail- ure in the online integration of the contextual information related to a thought, in partic- ular contextual information concerning the different causal factors that may be implicated in (...) their production. Loss of unity of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cog- nitive domains. We argue that it is also manifested in the process of thinking itself, result- ing in causally decontextualized thoughts that are experienced as inserted thoughts. (shrink)

A change in sense of self is an outcome commonly associated with Buddhist meditation. However, the sense of self is construed in multiple ways, and which changes in self-related processing are expected, intended, or possible through meditation is not well understood. In a qualitative study of meditation-related challenges, six discrete changes in sense of self were reported by Buddhist meditators: change in narrative self, loss of sense of ownership, loss of sense of agency, change (...) in sense of embodiment, change in self-other or self-world boundaries, and loss of sense of basic self. Changes in sense of self could be transient or enduring, positive or distressing, enhancing or impairing. These changes were also given varied appraisals, ranging from insights associated with Buddhist doctrines to psychopathologies such as depersonalization. In this study of practitioners reporting meditation-related challenges, more global changes in sense of self were associated with higher levels of impairment. These results have implications for both Buddhist meditation as well as mindfulness-based interventions. (shrink)
