This chapter offers an indirect defence of the Evansian conception of egocentric space, by showing how it resolves a puzzle concerning the unity of egocentric spatial perception. The chapter outlines several common assumptions about egocentric perspectival structure and argues that a subject’s experience, both within and across her sensory modalities, may involve multiple structures of this kind. This raises the question of how perspectival unity is achieved, such that these perspectival structures form a complex whole, rather (...) than merely disunified set of individually, distinctively structured experiences. The shortcomings of variety of accounts are considered: switch accounts ; sensory accounts; transformation accounts; and ultimate accounts. These shortcomings are addressed by a further kind of account provided by the Evansian conception – an agentive account – according to which egocentrically structured experiences present the world in relation to parts of a single thing, the body as a dynamic unity.

The posterior parietal cortex (PPC) is the most likely site where egocentric spatial relationships are represented in the brain. PPC cells receive visual, auditory, somaesthetic, and vestibular sensory inputs; oculomotor, head, limb, and body motor signals; and strong motivational projections from the limbic system. Their discharge increases not only when an animal moves towards a sensory target, but also when it directs its attention to it. PPC lesions have the opposite effect: sensory inattention and neglect. The PPC does not (...) seem to contain a “map” of the location of objects in space but a distributed neural network for transforming one set of sensory vectors into other sensory reference frames or into various motor coordinate systems. Which set of transformation rules is used probably depends on attention, which selectively enhances the synapses needed for making a particular sensory comparison or aiming a particular movement.

I discuss the relation between egocentric spatial representation and the capacity for bodily activity, with specific reference to Merleau-Ponty.

Neuropsychological findings used to motivate the "two visual systems" hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link between the spatial contents of visual experience and the perceiver's bodily actions. In this paper, I review and assess three (...) main sources of evidence for the two visual systems hypothesis. I argue that the best interpretation of the evidence is in fact consistent with both claims. I conclude with some brief remarks on the relation between visual consciousness and rational agency.

Space can be understood through perception and language, but are the processes that represent spatial information the same in both cases? This paper reviews psychological evidence for the functional equivalence of spatial representations based on perceptual and linguistic inputs. It is proposed that spatial information is processed by a specialised spatial representation system (SRS) that creates geometric representations of space. The SRS receives inputs from perceptual and linguistic systems and uses these basic inputs to construct mental spatial models (...) of the observed or described environment. A mental spatial model is created by determining the coordinate locations of objects in the egocentric or allocentric frame of reference. The goal of the SRS is not to represent strictly what is perceived, but to model an environment that has an inherent three‐dimensional spatial structure. (shrink)

Speakers of many languages prefer allocentric frames of reference (FoRs) when talking about small‐scale space, using words like “east” or “downhill.” Ethnographic work has suggested that this preference is also reflected in how such speakers gesture. Here, we investigate this possibility with a field experiment in Juchitán, Mexico. In Juchitán, a preferentially allocentric language (Isthmus Zapotec) coexists with a preferentially egocentric one (Spanish). Using a novel task, we elicited spontaneous co‐speech gestures about small‐scale motion events (e.g., toppling blocks) (...) in Zapotec‐dominant speakers and in balanced Zapotec‐Spanish bilinguals. Consistent with prior claims, speakers’ spontaneous gestures reliably reflected either an egocentric or allocentric FoR. The use of the egocentric FoR was predicted—not by speakers’ dominant language or the language they used in the task—but by mastery of words for “right” and “left,” as well as by properties of the event they were describing. Additionally, use of the egocentric FoR in gesture predicted its use in a separate nonlinguistic memory task, suggesting a cohesive cognitive style. Our results show that the use of spatial FoRs in gesture is pervasive, systematic, and shaped by several factors. Spatial gestures, like other forms of spatial conceptualization, are thus best understood within broader ecologies of communication and cognition. (shrink)

Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model (Trehub, 1977, 1991). This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate foveal (...) stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally-tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences. -/- Trehub, A.

b>: The problem of how physical systems, such as brains, come to represent themselves as subjects in an objective world is addressed. I develop an account of the requirements for this ability that draws on and refines work in a philosophical tradition that runs from Kant through Peter Strawson to Gareth Evans. The basic idea is that the ability to represent oneself as a subject in a world whose existence is independent of oneself involves the ability to represent space, (...) and in particular, to represent oneself as one object among others in an objective spatial realm. In parallel, I provide an account of how this ability, and the mechanisms that support it, are realized neurobiologically. This aspect of the article draws on, and refines, work done in the neurobiology and psychology of egocentric and allocentric spatial representation. (shrink)

How should we think about the role of visual spatial awareness in perception and perceptual knowledge? A common view, which finds a characteristic expression in Kant but has an intellectual heritage reaching back farther than that, is that an account of spatial awareness is fundamental to a theory of experience because spatiality is the defining characteristic of “outer sense”, of our perceptual awareness of how things are in the parts of the world that surround us. A natural counterpart to this (...) idea is to treat self-consciousness as residing in a kind of sense that is fundamentally “inner”, such as introspection or whatever else gives one privileged access to his own mental states as well as the proprioceptive and kinesthetic awareness of bodily position. This division is compatible, of course, with the idea that inner sense provides an awareness of a distinctive kind of “body space”, but it treats that as importantly different from the awareness of the worldly space around one. -/- In contrast to such a picture, this dissertation proposes an account of visual spatial awareness according to which it is no less a source of self-consciousness than of the awareness of the objects around us, and an account of self-awareness in which visual experience is essentially implicated. I begin by arguing that we should think of visual spatial awareness not as necessary for the individuation of visual sensations but rather as an essential element in the awareness of an experientially objective world. In the subsequent chapters, I argue that in being visually aware of the egocentric positions of the worldly objects around us we are often aware also of our own spatial locations with respect to them, and that the visual experience of the world around one and one’s own situation in it is often an essential component in the knowledge that a human agent will have of his own intentional actions.

One's contemporaneous conscious mental states seem bound in a single, unified experience. Dainton argues, against what he calls the S-Thesis, that we cannot explain such co-consciousness in terms of states' being located in a single phenomenal space, a functional space posited to explain our ability to locate ourselves relative to perceived stimuli. But Dainton's argument rests on a conflation of egocentric and allocentric self-localizing, and thus fails to undermine the S-Thesis. Nevertheless, experiments on visual neglect suggest one (...) can have unconscious mental states that are located in the same phenomenal field, so the S-Thesis fails after all. I examine a modified version of the S-Thesis according to which mental states are co-conscious when one is aware of them via a higher-order sensation that represents them as located in the same phenomenal field. But among other problems, this view fails to explain the co-consciousness of intentional states, which aren't located in phenomenal fields. Finally, I argue that a higher-order-thought model of consciousness best explains the apparent unity of experience in terms of one's tacit assumption that all the first-person thoughts in virtue of which one is conscious of one's mental states refer to the same individual.

This paper examines Milner and Goodale’s hypothesis about the two visual streams and raises the questions of whether properties in egocentric space (commonly associated with the vision-for-action, or "dorsal," stream) can be part of the phenomenal content of perceptual experience, or only properties in allocentric space (commonly associated with the vision-for-perception, or "ventral," stream) can play this role, and how (if at all) properties in egocentric space differ from properties in allocentric space. These questions (...) are reminiscent of issues raised by Christopher Peacocke's "equal-sized trees" case: if you are looking at equal-sized trees on the side of a road, the trees will phenomenally look to you to be equally tall. But it is also true that a tree will take up more of the space in your visual field the closer it is to you. So, the equal-sized trees will also phenomenally look to you to have different heights. Your (visual) perceptual experience is not illusory. That is, the trees veridically look to you to have the same height, and they also veridically look to you to have different heights. Call the sort of issue raised here the "problem of dual looks." I provide a solution to the problem of dual looks that helps shed light on whether properties in egocentric space can be part of the phenomenal content of perceptual experience, and how (if at all) properties in egocentric space differ from properties in allocentric space.

Spatial region concepts such as “front,” “back,” “left,” and “right” reflect our typical interaction with space, and the corresponding surrounding regions have different statuses in memory. We examined the representation of spatial directions in the auditory space, specifically in how far natural response actions, such as orientation movements toward a sound source, would affect the categorization of egocentric auditory space. While standing in the middle of a circle with 16 loudspeakers, participants were presented acoustic stimuli coming (...) from the loudspeakers in randomized order, and verbally described their directions by using the concept labels “front,” “back,” “left,” “right,” “front-right,” “front-left,” “back-right,” and “back-left.” Response actions varied in three blocked conditions: (1) facing front, (2) turning the head and upper body to face the stimulus, and (3) turning the head and upper body plus pointing with the hand and outstretched arm toward the stimulus. In addition to a protocol of the verbal utterances, motion capture and video recording generated a detailed corpus for subsequent analysis of the participants’ behavior. Chi-square tests revealed an effect of response condition for directions within the left and right sides. We conclude that movement-based response actions influence the representation of auditory space, especially within the sides’ regions. Moreover, the representation of auditory space favors the front and the back regions in terms of resolution, which is possibly related to the physiological characteristics of the human auditory system, as well as to the ecological requirements of action control in the different regions.

According to the decomposition thesis, perceptual experiences resolve without remainder into their different modality-specific components. Contrary to this view, I argue that certain cases of multisensory integration give rise to experiences representing features of a novel type. Through the coordinated use of bodily awareness—understood here as encompassing both proprioception and kinaesthesis—and the exteroceptive sensory modalities, one becomes perceptually responsive to spatial features whose instances couldn’t be represented by any of the contributing modalities functioning in isolation. I develop an argument for (...) this conclusion focusing on two cases: 3D shape perception in haptic touch and experiencing an object’s egocentric location in crossmodally accessible, environmental space.

Evidence from egocentric space is cited to support bicoding of navigation in three-dimensional space. Horizontal distances and space are processed differently from the vertical. Indeed, effector systems are compatible in horizontal space, but potentially incompatible (or chaotic) during transitions to vertical motion. Navigation involves changes in coordinates, and animal models of navigation indicate that time has an important role.

In this paper we consider the concept of a self-aware agent. In cognitive science agents are seen as embodied and interactively situated in worlds. We analyse the meanings attached to these terms in cognitive science and robotics, proposing a set of conditions for situatedness and embodiment, and examine the claim that internal representational schemas are largely unnecessary for intelligent behaviour in animats. We maintain that current situated and embodied animats cannot be ascribed even minimal self-awareness, and offer a six point (...) definition of embeddedness, constituting minimal conditions for the evolution of a sense of self. This leads to further analysis of the nature of embodiment and situatedness, and a consideration of whether virtual animats in virtual worlds could count as situated and embodied. We propose that self-aware agents must possess complex structures of self-directed goals; multi-modal sensory systems and a rich repertoire of interactions with their worlds. Finally, we argue that embedded agents will possess or evolve local co-ordinate systems, or points of view, relative to their current positions in space and time, and have a capacity to develop an egocentric space. None of these capabilities are possible without powerful internal representational capacities. (shrink)

The problem of amodal perception is the problem of how we represent features of perceived objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently proposed that we amodally perceive an object's occluded features by imaginatively projecting them into the relevant regions of visual egocentric space. In this paper, I argue that amodal perception is not a single, unitary capacity. Drawing appropriate distinctions reveals amodal perception to be characterized not only by mental imagery, as (...) Nanay suggests, but also by genuinely visual representations as well as beliefs. I conclude with some brief remarks on the role of object-directed bodily action in conferring a sense of unseen presence on an object's occluded features. (shrink)

It has been claimed that photographs are transparent: we see through them; we literally see the photographed object through the photograph. Whether this claim is true depends on the way we conceive of seeing. There has been a controversy about whether localizing the perceived object in one's egocentric space is a necessary feature of seeing, as if it is, then photographs are unlikely to be transparent. I would like to propose and defend another, much weaker, necessary condition for (...) seeing: I argue that it is necessary for seeing that there is at least one way for me to move such that if I were to move this way, my view of the perceived object would change continuously as I move. Since this condition is not satisfied in the case of seeing objects in photographs, photographs are not transparent. (shrink)

The projection of conscious content is a central feature of Max Velmans' theory of consciousness, implying that conscious experiences are built within a conversation of minds and worlds in which they form a 'reflexive' unity – as stated in his reflexive monism theory. What are the neurobiological structures and functions that underpin the experience of conscious contents being located in a spatio-temporal frame outside the nervous system that instantiates them? In this paper I offer informed speculation about these neurobiological structures (...) on the basis of the concept of projection within the psychophysical 'egocentric space', having the central nervous system at the origin of coordinates and the interface with the environment as the horizon. The reasoning is based on the work of several neuroscientists on feedback signals from the motor to sensory neuron systems, building a picture of how they support the projective process. I also call attention to the integrative role of glial cells in the generation of localized sensations and other conscious contents. (shrink)

Patients may show a more-or-less complete deviation of the head and eyes towards the right (ipsilesional) side [that is, to the same side of egocentric space as the brain lesion responsible for their disorder]. If addressed by the examiner from the left (contralesional) side [the opposite side to their lesion], patients with severe extrapersonal neglect may fail to respond or may look for the speaker in the right side of the room, turning head and eyes more and more (...) to the right. Frequently these patients will not pick up food from the left half of the plate. Given a crossword puzzle, they may complete only the squares to the right. If walking is not prevented by hemiparesis, neglect patients may lose their bearings, since they do not make use of left sided cues. (shrink)

En The Varieties of Reference, Evans sostiene que el contenido perceptual posee una naturaleza no conceptual. Precisamente, los vínculos informacionales entre sujeto y objeto habilitan el pensamiento singular, al permitir la localización del objeto en un entorno egocéntrico. Anclados en algunos casos en estos vínculos, los pensamientos singulares contienen Ideas adecuadas del objeto, dependientes de una determinada clasificación del mismo. Nada en el contenido perceptual equivale a este recorte conceptual del objeto en el pensamiento. Sostendré entonces la necesidad de introducir (...) la idea de una representación no conceptual de cosa que recortaría, de dicho contenido, un punto de anclaje para la representación informacional. In The Varieties of Reference, Evans claims that perceptual content has a non-conceptual nature. Concretely, the informational links between subject and object allow singular thought by permitting the localization of the object in an egocentric space. Anchored in some cases in these links, singular thoughts contain adequate Ideas of the object that depend on a certain classification of it. Nothing in the perceptual content corresponds to this conceptual cut of the object in thought. I will therefore underline the need to introduce the idea of a non-conceptual representation of thing that will cut, in that content, an anchoring point for the informational representation.

Despite the large interest in the human ability to perceive space present in neuroscience, cognitive science and psychology, as well as philosophy of mind, the issues regarding egocentric space representation received relatively less attention. In this paper I take up a unique phenomenon related to this faculty: the “spatial purport” of perceptual experiences. The notion was proposed by Rick Grush to describe the subjective, qualitative aspects of egocentric representations of spatial properties and relations. Although Grush offered (...) an explanation of the mechanism giving rise to appearance of spatial purport, his model had considerable shortcomings. In the paper I thoroughly analyze both the notion of spatial purport and Grush’s explanation of the mechanism at its core in order to develop his theory using the insights provided by the predictive processing theory of mind, and more particularly by the active inference framework. The extended account I offer, named Predictive and Hierarchical Skill Theory, explains phenomena that escaped Grush’s model and furthers the research on egocentric space representation from the perspective of both neuroscience and philosophy of mind.

Activation of the brainʼs putative retinoid system has been proposed as the neuronal substrate for our basic sense of being centered within a volumetric surround –- our minimal phenomenal consciousness (Trehub 2007). Here, the assumed properties of the self-locus within the retinoid model are shown to explain recent experimental findings relating to the out-of-body-experience. In addition, selective excursion of the heuristic self-locus is able to explain many important functions of consciousness, including the effective internal representation of a 3D space (...) on the basis of 2D perspective depictions. Our sense of self-agency is shown to be a natural product of the role of the heuristic self-locus in the retinoid mechanism. (shrink)

In this article, we offer a critical realist conception of curriculum that aims to cultivate critical thinking (CT) and liberate students from egocentric rationality. We first examine egocentric rationality as a problem emerging from the technicist paradigm of cultivating CT in higher education, exemplified by issues arising from the pedagogical activity of debate. We then examine existing approaches to cultivating CT, focusing on the extent to which their goals and conceptions of CT could liberate students from egocentric (...) rationality. Drawing on Roy Bhaskar’s stratified conception of being and principle of immanent critique, we offer a critical realist conception of curriculum, explaining its definition of CT as the capacity for self-critique. We shall illustrate, in the context of an undergraduate debate course, how such capacity can be developed in order to liberate students from egocentric rationality. Curriculum is thus a critical praxis, a created space where student’s CT develops in a way that is intrinsically entwined with their being and becoming. This article extends the philosophical basis for integrating CT with curriculum and offers pedagogical implications. (shrink)

Our perception of where touch occurs on our skin shapes our interactions with the world. Most accounts of cutaneous localisation emphasise spatial transformations from a skin-based reference frame into body-centred and external egocentric coordinates. We investigated another possible method of tactile localisation based on an intrinsic perception of ‘skin space’. The arrangement of cutaneous receptive fields (RFs) could allow one to track a stimulus as it moves across the skin, similarly to the way animals navigate using path integration. (...) We applied curved tactile motions to the hands of human volunteers. Participants identified the location midway between the start and end points of each motion path. Their bisection judgements were systematically biased towards the integrated motion path, consistent with the characteristic inward error that occurs in navigation by path integration. We thus showed that integration of continuous sensory inputs across several tactile RFs provides an intrinsic mechanism for spatial perception. (shrink)

The indexical sentence “I am here now” can be used any time and anywhere by anyone to say something true. Rather than yielding a special kind of infallible knowledge, this fact indicates that every speaker or thinker has a zero of an egocentric coordinate system at his disposal. Many idealist philosophers assume that this egocentric zero can be further reduced. The ability to make a de se-reference with the first person pronoun, they claim, need not involve spatiotemporal self-localization. (...) The paper challenges this idealistic view. Starting from the observation that even Descartes’ cogito argument, which expresses a tensed truth, involves a dated mental episode, it is argued that nothing can exist in time without being in space. The paper concludes that the egocentric zero of orientation with its three mutually dependent elements (I, here, now) cannot be further minimized. Thinkers of I-thoughts must have a spatiotemporal position. They must be Strawsonian persons rather than Cartesian egos. (shrink)

Perception and conceptualization of space are some of the most basic elements of human cognition. It has been long assumed that human spatial thinkingand frames of reference used to grasp and describe the location of an object in relation to other objects are of universal nature and so are projected in naturallanguages in basically the same manner; three principal dimensions in egocentric perceptual space were distinguished: up-down, front-back and left-right, reflecting our biological make-up. If differences in spatial (...) terminology were observed, they were relegated to surface structure phenomena, but were not regarded as differences in perceptual and conceptual representations in the human mind. That belief in the universal perception of spatial relations among humans was ofconsiderable importance for some philosophical theories, also for Husserl’s conception of the Lebenswelt a priori and his defence of the validity of scientificpropositions and of absolute truth. It now appears that the extent of the diversity in spatial thinking has been drastically underestimated (Levinson 2003), but it does not follow that Husserl’s intuitions regarding the existence of universal constituents in incompatible Lebenswelt experiences were necessarily wrong.

The present paper explores the phenomenology of disorientation and its relationship with self-consciousness. Section 1 discusses previous literature on the links between self-location and self-consciousness and proposes a distinction between minimal self-location and integrated self-location. The double aim of the paper is to use this distinction to deepen our understanding of spatial disorientation, and to use the phenomenology of disorientation to elucidate the role that integrated self-location plays in shaping self-consciousness. Section 2 starts by looking at the experience of being (...) “turned around”, which is a common experience of disorientation. This analysis leads to the conclusion that integrated self-location is transmodal and depends on all three egocentric axes, and that disorientation destabilizes this integrated self-location. Section 3 explores a corpus of reports of disorientation episodes and highlights four key characteristics of these experiences and their links to self-consciousness, focusing on the transformations in both the lived body and the experience of space. The central thesis of this paper is that during disorientation a destabilization of integrated self-location results in a diminished form of self-consciousness. (shrink)

By “essentially embodied Kantian selves,” I mean necessarily and completely embodied rational conscious, self-conscious, sensible (i.e., sense-perceiving, imagining, and emoting), volitional or willing, discursive (i.e., conceptualizing, judging, and inferring) animals, or persons, innately possessing dignity, and fully capable not only of free agency, but also of a priori knowledge of analytic and synthetic a priori truths alike, with egocentric centering in manifestly real orientable space and time. The basic theory of essentially embodied Kantian selves was spelled out by (...) Kant over the course of slightly less than two decades, between 1768 and 1787, but above all, it flows from an empirical realist and metaphysical reading of the “Refutation of Idealism” that Kant inserted into the Postulates of Empirical Thought section in the 1787 edition of the first Critique. In my opinion, all rational but also “human, all-too-human” creatures like us are, synthetic a priori necessarily, essentially embodied Kantian selves. Let’s call that the essentially embodied Kantian selves thesis, or for short, EEKST. If EEKST is true, then it’s synthetic a priori impossible for the selves of creatures like us to exist independently of our own living organismic animal bodies or beyond the deaths of those bodies, whether temporarily or permanently, by any means whatsoever. Indeed, the very ideas of disembodied selves, their survival after death, and of human immortality, while minimally logically consistent, are in fact conceptually empty and incoherent, even over and above the synthetic a priori impossibility of such things, since the term “myself” indexically picks out an essentially embodied Kantian self, all of whose core features require grounding in a particular living organismic animal body. According to the recent and contemporary movement of transhumanism, the selves of creatures like us can not only exist independently of our bodies, as functional systems of representational content that are inherently able to be implemented or realized in digital-mechanical technology and uploadable to servers, but also to survive accidental or natural human death in server-limbo, then be downloaded into technologically enhanced partially mechanical humanoid bodies or even into wholly artificially-created completely mechanical non-humanoid bodies, survive in these new implementations or realizations for an indefinitely long time, repeat that process, and possibly even become immortal. Transhumanism is in fact metaphysically equivalent to Swedenborgianism, which Kant so effectively criticizes and wittily derides in his 1766 book, Dreams of a Spirit-Seer Elucidated by Dreams of Metaphysics. Moreover, and more importantly, if EEKST is true, then, just like Swedenborgianism, transhumanism is not only conceptually empty and incoherent, but also synthetic a priori impossible. And what’s more, it’s also existentially and morally reprehensible. In short, then, the belief in transhuman selves is nothing but a reprehensible noumenal fantasy or Hirngespinst. (shrink)

[full article, abstract in English; only abstract in Lithuanian] Walton’s thesis of transparency of photographs has spurred much dispute among critics. One of the popular objections is spatial agnosticism, an argument that concerns the inertia of egocentric spatial information vis-a-vis a photograph. In this paper, I argue that spatial agnosticism fails. Spatial agnostics claim, for a wrong reason, that a photographic image cannot carry egocentric spatial information. I argue that it is the disjuncture of the photographic world in (...) which the depicted object situated from the space in which the viewer of the photograph resides that renders the photograph spatially agnostic. It is the timeless photographic world rather than the photographic object that renders egocentric spatial information inert. With this new formulation of spatial agnosticism, I propose that spatial agnosticism needs to be coupled with the temporal dimension in the efforts to refute the thesis of transparency of photographs.

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)

There is an ongoing debate regarding the content of psychopathy, especially about the status of antisocial behavior and disinhibition characteristics as core psychopathy features. Psychopathic Personality Traits Scale (PPTS) represents a novel model of psychopathy based on core psychopathy markers such as Interpersonal manipulation, Egocentricity and Affective responsiveness. However, this model presupposes another narrow trait of psychopathy: cognitive responsiveness, which represents a lack of cognitive empathy. Since previous models of psychopathy do not depict this feature as a core psychopathy trait, (...) the goal of this study was to empirically evaluate if the lack of cognitive empathy is a narrow psychopathy trait or its correlate. The research was conducted on a community sample via online study (N=342; Mage=23.7 years; 31% males). Results showed that the correlations between Cognitive responsiveness and other psychopathy features were significantly lower than intercorrelations of other three traits. Factor analysis, conducted on PPTS items, provided a two-factor solution, where Cognitive responsiveness was yielded as a factor separate from other psychopathy indicators. Finally, the exploration of the shared latent space of psychopathy and cognitive empathy resulted in the two-factor solution where psychopathy and the lack of cognitive empathy were extracted as correlated but separate latent variables. The data clearly supported the former model. Research results showed that the lack of cognitive empathy should not be considered an indicator of psychopathy but its correlate. The findings emphasize the need to be cautious in conceptualization of the psychopathy construct. (shrink)

Humans use their spatial information processing abilities flexibly to facilitate problem solving and decision making in a variety of tasks. This article explores the question of whether a general strategy can be adapted for performing two different spatial orientation tasks by testing the predictions of a computational cognitive model. Human performance was measured on an orientation task requiring participants to identify the location of a target either on a map (find‐on‐map) or within an egocentric view of a space (...) (find‐in‐scene). A general strategy instantiated in a computational cognitive model of the find‐on‐map task, based on the results from Gunzelmann and Anderson (2006), was adapted to perform both tasks and used to generate performance predictions for a new study. The qualitative fit of the model to the human data supports the view that participants were able to tailor a general strategy to the requirements of particular spatial tasks. The quantitative differences between the predictions of the model and the performance of human participants in the new experiment expose individual differences in sample populations. The model provides a means of accounting for those differences and a framework for understanding how human spatial abilities are applied to naturalistic spatial tasks that involve reasoning with maps.

There is a need for inner recollection opposed to our everyday distraction. Our distraction is partly based on anthropological features and partly on social and cultural features. As well as feelings of distraction, we know experiences of being focussed from everyday life. As feelings in which distraction is absent, and as feelings in which we are partly and temporarily released from our own egocentric perspective, they remind us that a different kind of relation to ourselves and the world is (...) possible. Therefore, they can motivate a process of self-transformation aiming at a mystical state of mind, which is of a more profound and enduring kind than ordinary experiences of being focussed. The mystical state of mind is a state in which we transcend ourselves in the face of the universe and thereby relativize our own affective involvement. It is a feeling of an all-encompassing unity which ultimately concerns us; and it is a feeling of love, joy, and peace of mind. Mystical feelings thus shape and restrict spaces of possibilities, and they comprise an altered sense of what it means to be real. Therefore, they can be classified as existential feelings. Still, the mystical state of mind differs from prototypical existential feelings because it is a positive feeling, necessarily comprises active as well as passive moments, and presupposes an explicit way of attending to the world as world.

I have argued elsewhere that imagery and represention are best explained as the result of operations of neurally implemented emulators of an agent's body and environment. In this article I extend the theory of emulation to address perceptual processing as well. The key notion will be that of an emulator of an agent's egocentric behavioral space. This emulator, when run off-line, produces mental imagery, including transformations such as visual image rotations. However, while on-line, it is used to process (...) information from sensory systems, resulting in perception (in this regard, the theory is similar to that proposed by Kosslyn (1994)). This emulator is what provides the theory in theory-laden perception. I close by arguing briefly that the spatial character of perception is to be explained as the contribution of the egocentric behavioral space emulator. (shrink)

This article proceeds from a consideration of what John Baldacchino calls ‘viable ignorance’, attempting to take leave from the critical and pedagogical obligations of certain elements of Barbara Johnson's ‘positive ignorance’. It considers Friedrich Nietzsche, Jean-François Lyotard and the composer, Karlheinz Stockhausen's reflections on modes of experience, and the cultivation of complementary dispositions, where the knowing, egocentric subject is transformed into, or undermined as, what Nietzsche calls ‘a medium of overpowering forces’. The disposition itself is outlined through close readings (...) of key elements of Nietzsche's notebooks, Lyotard's final chapter of Libidinal Economy (1993), and Stockhausen's lecture, ‘Intuitive Music’ (1971) and developed through supplemental practice-as-research activity in sound. The intention of this paper is to explore the space of aesthetic ignorance as committedly as possible, without reverting constantly to positive ignorance. (shrink)

A common and popular option in defending Physicalism against the Knowledge Argument is the “phenomenal concept strategy” . PCS claims that, although ex hypothesi Mary knows all the propositions pertaining to color and experiences of color, there is at least space for the claim that she acquires a new concept, and thereby accesses these propositions under different, phenomenal modes of presentation. In short, Mary acquires new concepts upon her release and that explains her “discovery.” Here I will show there (...) is a way of saving Physicalism that does not appeal to PCS in the standard sense but entails that Mary acquires the ability to think a new kind of singular thought. In acquiring this, she gains a kind of indexical, egocentric knowledge. (shrink)

In bodily awareness body parts are felt to occupy locations relative to the rest of the body. Bodily sensations are felt to be, in Brian O’Shaughnessy’s terms ‘in-a-certain-body-part-at-a-position-in-body-relative-physical-space’. In this paper I put forward a dispositional account of the structure of the spatial content of bodily awareness, which takes inspiration from Gareth Evans’s account of egocentric spatial content in The Varieties of Reference. On the Dispositional View, bodily awareness experiences have spatial content in virtue of a set of (...) connections having been established between somatosensory and proprioceptive inputs on the one hand, and motor outputs on the other hand. This kind of account, according to which spatial content depends constitutively on bodily action, has been challenged by a set of neurological cases and behavioural studies on healthy subjects. The evidence has been used to motivate a functional distinction between two kinds of body representation: representations for perception and representations for action. I review and assess some of the main sources of evidence for this distinction, arguing that the evidence presents a challenge to the dispositional view only if we accept the unjustified assumption that differences in task performance can only be explained in terms of a difference in representation. I close by proposing, and offering some empirical support for, an alternative explanation of the empirical results. The availability of the alternative explanation means that further work is needed to establish whether or not there is any challenge to the Dispositional View. (shrink)

We present a spatial system called Specialized Egocentrically Coordinated Spaces embedded in an embodied cognitive architecture (ACT-R Embodied). We show how the spatial system works by modeling two different developmental findings: gaze-following and Level 1 perspective taking. The gaze-following model is based on an experiment by Corkum and Moore (1998), whereas the Level 1 visual perspective-taking model is based on an experiment by Moll and Tomasello (2006). The models run on an embodied robotic system.

We identify two aspects of the problem of maintaining perceptual stability despite an observer's eye movements. The first, visual direction constancy, is the (egocentric) stability of apparent positions of objects in the visual world relative to the perceiver. The second, visual position constancy, is the (exocentric) stability of positions of objects relative to each other. We analyze the constancy of visual direction despite saccadic eye movements.Three information sources have been proposed to enable the visual system to achieve stability: the (...) structure of the visual field, proprioceptive inflow, and a copy of neural efference or outflow to the extraocular muscles. None of these sources by itself provides adequate information to achieve visual direction constancy; present evidence indicates that all three are used.Our final question concerns how information processing operations result in a stable world. The three traditionally suggested means have been elimination, translation, or evaluation. All are rejected. From a review of the physiological and psychological evidence we conclude that no subtraction, compensation, or evaluation need take place. The problem for which these solutions were developed turns out to be a false one. We propose a “calibration” solution: correct spatiotopic positions are calculated anew for each fixation. Inflow, outflow, and retinal sources are used in this calculation: saccadic suppression of displacement bridges the errors between these sources and the actual extent of movement. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:258 HISTORY OF PHILOSOPHY and diversity"-- ("it is useless to deny or even minimize the incongruities and the contradictions" in Rousseau's statements, as Burgelin says in another book). Instead he puts the finger on the one trait that sets this piece of rationalism (or anti-rationalism, as some would say) apart from all others: not sentiment verging on the mystical, but egocentrism, existentially founded and unique. Rousseau, taking a stand (...) outside the battling parties, outside his own religion, becomes more and more "une existence solitaire en face d'une autre existence, qui le regarde," that "other existence" which he calls God. Alas, the descent from such existential heights is swift. Soon the solitary thinker will be enmeshed again in unsolitary speculations about those very issues he had left behind in his flight into the self. Where will this strange pilgrim's progress end? In 1769, seven years before his death and feeling the cold breath of old age upon him, Jean-Jacques wrote: "In my childhood I believed by authority, in my youth by feeling, in my mature age by reason; now I believe because I have always believed." Burgelin cites this as proof that Rousseau never ceased to believe. Maybe so. But is this the point? What the passage defines is the pilgrim's irreversible religious itinerary. On cannot but ask what the next inevitable stop on the road would have been. Waiting for Godot? "Whoever makes an effort to find in Rousseau's work an explicit philosophy... runs into a very peculiar difficulty, for a philosophy is defined above all by its coherence, and [Rousseau] himself warns us against his own methods." With these words Pierre Burgelin opened his monumental work, La philosophic de l'existence de ].-]. Rousseau (1952). It is in the several pertinent chapters of this earlier work that the reader will find what the present book withholds: a philosophical analysis as rigorous as it is profound and comprehensive, the best analysis we have to Rousseau's religious thought. Professor Burgelin's new book merely proves that not even he can do justice to Jean-Jacques without explaining him. GREGORSEBBA Emory University l~mile ou de l'dducation. Par Jean-Jacques Rousseau. Introduction, bibliographic, notes, et index analytique par Francois et Pierre Richard. gdition illustr~e. (Paris: ~ditions Garnier Fr~res, 1962. Pp. 1 + 664 [1].) While the new Pldiade edition of Rousseau, a model of contemporary French scholarship, makes its slow, stately way towards completion, the well-known yellow Classiques Garnier keep coming out in new editions or simply in new dress. This 12mile is a handsomely produced, very readable BOOK REVIEWS 259 reissue of the 1939 Garnier edition, with reproductions of eighteenthcentury engravings on themes of Rousseau. They add rich period flavor to this strange work in which a hypermodern intelligence talks the language of three centuries ago. There are useful notes, the detailed subject index is exceptionally well laid out, the spacious bibliography is ample for Rousseau 's sources and influence, but its meager twentieth-century section should have been reworked and brought up to date. The Introduction, too, can still be read with much profit, even though its critical standpoint is now antiquated, eloquent proof of the effectiveness of Rousseau scholarship in the last two decades. For its price this is a very handy, serviceable edition to have until the Biblioth~que de la PMiade catches up with Garnier Fr~res. Emory University GREGOR SEBBA Kant's Theory o[ Knowledge. By Graham Bird. (New York: The Humanities Press, 1962. Pp. x + 210. ~5.50.) In the Preface the author states that he has two main objectives in his book: To pursue one central argument through the Critique of Pure Reason and to discuss Kant's views in terms of a modern philosophical idiom. Bird follows this programme out through most of the book, departing from it on only one occasion, in Chapter 11 (pp. 181-188) in which he discusses and criticizes Strawson's theory of personality (as presented in his book Individuals, chap. 3). The space given to Strawson does not, however, constitute a serious digression from the main argument because it comes at the end of a chapter devoted... (shrink)

This essay presents central themes from my forthcoming book, The Awakening of the Global Mind. This book seeks to open a new frontier of Global Consciousness that has been long emerging in human evolution through the ages. When we step back from our more localized perspectives and expand into a more integral, holistic, and global space through the awakening of the global mind we are able to discern striking mega-trends in cultural evolution across diverse cultural and religious worldviews and (...) perspectives through time. One striking finding through this global lens is that the collective wisdom of humanity is quite clear that we make our living realities through the conduct of our consciousness: our technology of minding. And when we make ourselves and worlds through egocentric patterns of thinking we get polarized and fragmented worlds that are not sustainable. This essay joins a growing chorus of visionary thinkers and futurists which recognizes that in the 21st Century we face grave planetary crises and that our ego-based cultures are at a tipping point and not sustainable. The primary crisis on the planet now is a crisis of consciousness, and our global wisdom suggests that humanity is in a painful transformation toward a more healthful integral technology of mind that ushers in a new sustainable global civilization wherein the whole human family may flourish together on our sacred planet.
