This paper contributes an analysis and formalization of Damasio's theory on core consciousness. Three important concepts in this theory are 'emotion', 'feeling' and 'feeling a feeling' (or core consciousness). In particular, a simulation model is described of the dynamics of basic mechanisms leading via emotion and feeling to core consciousness, and dynamic properties are formally specified that hold for these dynamics at a more global level. These properties have been automatically checked for the simulation model. Moreover, a formal analysis is made of relevant notions of representation used by Damasio. As part of this analysis, specifications of representation relations have been verified and confirmed against the simulation model.  相似文献

This article summarizes a variety of current as well as previous research in support of a new theory of consciousness. Evidence has been steadily accumulating that information about a stimulus complex is distributed to many neuronal populations dispersed throughout the brain and is represented by the departure from randomness of the temporal pattern of neural discharges within these large ensembles. Zero phase lag synchronization occurs between discharges of neurons in different brain regions and is enhanced by presentation of stimuli. This evidence further suggests that spatiotemporal patterns of coherence, which have been identified by spatial principal component analysis, may encode a multidimensional representation of a present or past event. How such distributed information is integrated into a holistic precept constitutes the binding problem. How a precept defined by a spatial distribution of nonrandomness can be subjectively experienced constitutes the problem of consciousness. Explanations based on a discrete connectionistic network cannot be reconciled with the relevant facts. Evidence is presented herein of invariant features of brain electrical activity found to change reversibly with loss and return of consciousness in a study of 176 patients anesthetized during surgical procedures. A review of relevant research areas, as well as the anesthesia data, leads to a postulation that consciousness is a property of quantum-like processes, within a brain field resonating within a core of structures, which may be the neural substrate of consciousness. This core includes regions of the prefrontal cortex, the frontal cortex, the pre- and paracentral cortex, thalamus, limbic system, and basal ganglia.  相似文献

Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situation is getting confusing because some theorists formulate their models without making reference to existing views, redundantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of self-focus, amount of self-related information, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extended, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature--e.g., consciousness in relation to mirror self-recognition and language.  相似文献

Despite the broad application of feminist techniques and advances in defining feminist theory for psychological practice, consensus regarding the effectiveness of core components and techniques specific to feminist therapy is still evolving. This paper identifies four core components of feminist therapy: consciousness raising, social and gender role analysis, resocialization and social activism, and evaluates existing research evaluating their therapeutic effectiveness. Research to date suggests that many of these core components are promising. Future research on each of these key components is proposed.  相似文献

Consciousness and the brainstem   总被引:1,自引:0,他引:1  
Parvizi J  Damasio A 《Cognition》2001,79(1-2):135-160
In the first part of this article we summarize a theoretical framework and a set of hypotheses aimed at accounting for consciousness in neurobiological terms. The basic form of consciousness, core consciousness is placed in the context of life regulation; it is seen as yet another level of biological processing aimed at ensuring the homeostatic balance of a living organism; and the representation of the current organism state within somato-sensing structures is seen as critical to its development. Core consciousness is conceived as the imaged relationship of the interaction between an object and the changed organism state it causes. In the second part of the article we discuss the functional neuroanatomy of nuclei in the brainstem reticular formation because they constitute the basic set of somato-sensing structures necessary for core consciousness and its core self to emerge. The close relationship between the mechanisms underlying cortical activation and the bioregulatory mechanisms outlined here is entirely compatible with the classical idea that the reticular formation modulates the electrophysiological activity of the cerebral cortex. However, in the perspective presented here, that modulation is placed in the setting of the organism's homeostatic regulation.  相似文献

It has been suggested (Block, 2007) that the core neural bases for visual phenomenal consciousness and for access consciousness are located in anatomically separate regions. If this is correct, and if, as Block suggests, the core neural substrate of visual phenomenality is located early in the visual cortex where detailed chromatic information is available, then it would be reasonable to infer that our intuitions of chromatically rich visual phenomenality are plausible. It is furthermore suggested that during perception cognitive access to this chromatic cornucopia is mediated through mereologically superordinate (MS) concepts that regionally characterize both semantic and quantitative integrated properties within complex visual percepts. Such concepts contain much less information than do the particulars that they characterize, implying that the information represented in phenomenal consciousness greatly exceeds the information in the accompanying access consciousness.  相似文献

Nye's (1998) core construct of relational consciousness in child spirituality embraces a wider dialogue with social and personality psychology. Relatedness in spirituality implies the importance of language, mind, and the self as guideposts for development. In this research we seek to qualitatively expand our understanding of relational consciousness around recent work in these three domains. Twelve school-age children are given detailed interviews dealing with spirituality framed by the relational consciousness core construct. Transcribed responses are analysed using grounded theory methodology. Theoretical categories are assembled into a preliminary framework for relational consciousness as a social and contextual phenomenon. The relationships between categories in the framework are outlined in terms of mental representation and self/other orientation in the child. We conclude that relational consciousness and its social framework commends a pedocentric, community-based approach to religious education.  相似文献

This article is an attempt to situate imagination within consciousness complete with its own pre-cognitive, cognitive, and meta-cognitive domains. In the first sections we briefly review traditional philosophical and psychological conceptions of the imagination. The majority have viewed perception and imagination as separate faculties, performing distinct functions. A return to a phenomenological account of the imagination suggests that divisions between perception and imagination are transcended by precognitive factors of sense of reality and non-reality where perception and imagination play an indivisible role. In fact, both imagination and perception define sense of reality jointly according to what is possible and not possible. Absorption in a possible world depends on the strengths of alternative possibilities, and the relationship between core and marginal consciousness. The model may offer a parsimonious account of different states and levels of imaginal consciousness, and of how "believed-in imaginings" develop and become under some circumstances "lived-in experiences."  相似文献

Neural Darwinism (ND) is a large scale selectionist theory of brain development and function that has been hypothesized to relate to consciousness. According to ND, consciousness is entailed by reentrant interactions among neuronal populations in the thalamocortical system (the 'dynamic core'). These interactions, which permit high-order discriminations among possible core states, confer selective advantages on organisms possessing them by linking current perceptual events to a past history of value-dependent learning. Here, we assess the consistency of ND with 16 widely recognized properties of consciousness, both physiological (for example, consciousness is associated with widespread, relatively fast, low amplitude interactions in the thalamocortical system), and phenomenal (for example, consciousness involves the existence of a private flow of events available only to the experiencing subject). While no theory accounts fully for all of these properties at present, we find that ND and its recent extensions fare well.  相似文献

With insight from the methodology of phenomenology, Jan Patočka draws multiple meanings from the special front-line experience, including new understanding of the fringe of death, absolute freedom, universal responsibility, and solidarity with enemies. The front-line experience is in sharp contrast with daily life experience, and is regarded by Patočka as a continuous consciousness of problematization toward history. This consciousness, which the front-line experience gives rise to, can be maintained through true care for reality and history. Patočka names this “care for the soul” and regards it as the core of the European spirit. The potential philosophical and historical value of the front-line experience urges Patočka to maintain an eternal fight, and he eventually concludes that it is this eternal fight that brings forth eternal peace.  相似文献

The standard behavioral index for human consciousness is the ability to report events with accuracy. While this method is routinely used for scientific and medical applications in humans, it is not easy to generalize to other species. Brain evidence may lend itself more easily to comparative testing. Human consciousness involves widespread, relatively fast low-amplitude interactions in the thalamocortical core of the brain, driven by current tasks and conditions. These features have also been found in other mammals, which suggests that consciousness is a major biological adaptation in mammals. We suggest more than a dozen additional properties of human consciousness that may be used to test comparative predictions. Such homologies are necessarily more remote in non-mammals, which do not share the thalamocortical complex. However, as we learn more we may be able to make "deeper" predictions that apply to some birds, reptiles, large-brained invertebrates, and perhaps other species.  相似文献

Consciousness represents the core of the new paradigm, the unitary, systemic vision, and comprehension that emerges in every field of science, culture, and spirituality. For centuries, consciousness has been divided from matter, the soul from the physical body. Now, in this historical beginning of globalization, we need a new holistic model, a global paradigm based on consciousness that can explain the unitary evolutionary process, the psychosomatic unity of human being, the neurophysiological roots of harmony between peoples and the way to personal and collective evolution of consciousness in order to realize a more conscious, peaceful, and sustainable planetary future. Consciousness is the key of human evolution.  相似文献

SUMMARY

Core energetics is a method of psychotherapy that seeks the integration of all aspects of humanity: the emotional, physical, mental, and spiritual. Based on a deep understanding of the ways in which energy and consciousness work together, the therapy, developed by John C. Pierrakos, MD, invites couples to experience their inner truth and to identify their universal life goals and core feelings. Core energetics emphasizes wholeness and unification without loss of individuation for the couple. This article describes core energetics as it is used in couples work; the theory, therapeutic stance, methods of diagnosis, and energetic techniques are discussed, as well as the focus on sexuality and Spirituality.  相似文献

Abstract

At the core of Kant’s Critique of Pure Reason was a decisive break with certain fundamental Cartesian assumptions or claims about consciousness and self-consciousness, claims that have nonetheless remained perennially tempting, from a phenomenological perspective, independently of any further questions concerning the metaphysics of mind and its place in nature. The core of this philosophical problem has recently been helpfully exposed and insightfully probed in Dan Zahavi’s book, Self and Other: Exploring Subjectivity, Empathy, and Shame (OUP, 2014). In these remarks I suggest that Zahavi’s view of what he calls ‘The Experiential Self’ defends precisely the sorts of claims to which a Kantian account of consciousness is fundamentally opposed, and while assessing the overall merits of the two contrasting outlooks is no easy matter, I side with the Kantian view.  相似文献

“认知科学”与“第二代认知科学”刍议   总被引:6,自引:0,他引:6  
李其维 《心理学报》2008,40(12):1306-1327
以计算隐喻为核心假设的传统认知心理学以及联结主义心理学均不能克服离身心智(disembodied mind)的根本缺陷,当代认知心理学正面临着新的范型转换。以具身性和情境性为重要特征的第二代认知科学将日受重视,并促使认知神经科学进入新的发展阶段。作者认为在身心关系上应该坚持生理只是心理的必要条件,而非充分条件的立场,克服生理还原论的危险;应该重新审视基于二元论的生理机制这种说法;心理学传统中的科学主义和人文主义有可能在第二代认知科学强调认知情境性的基础上达成某种融合;第一代认知科学对意识的研究是不成功的,因为对知觉、注意、记忆、思维等心理过程的研究不能代替意识的研究,同时还应避免以意识内容的研究取代心理学研究的倾向。第二代认知科学中的动力系统理论关于变量(因素)之间的偶合(coupling)关系完全不同于变差分析中的变量之间的交互作用关系”,其动力系统模式可能更有助于破解意识的产生(涌现)之谜,并引发心理学研究的方法论的变革新潮。第二代认知科学的兴起将启发人们对身心关系、生理还原论、意识研究在心理学中的地位、人工智能对心智完全模拟的可能性等重大问题重新思考  相似文献

Extended cognition theorists claim that the definition of cognition can be extended to include not only the brain, but also the body and environment. In a series of works, Mark Rowlands has envisioned a new science of mind that explores the externalism of consciousness and cognition. This paper connects Rowlands’ work with the phenomenology of Aron Gurwitsch. It shows how Gurwitsch’s field of consciousness, in particular his conception of the marginal halo, can provide a distinct, organized way of thinking about extended cognition. A key question considered is from where do cognitive processes project and disclose meanings? By thinking of location as locus—a projecting pathway of points of intentional opportunity—organization in extended cognition becomes organization in a field of consciousness. The marginal halo in the field of consciousness is articulated as this locus of intentionality, what Rowlands (The new science of the mind: from extended mind to embodied phenomenology, MIT Press, Cambridge, 2010) calls “the noneliminable intentional core”. Problems of cognitive bloat and personal character are addressed in light of the findings. In addition to situating Gurwitsch’s work within the extended mind movement for the first time, this study highlights the importance of the marginal halo, largely neglected in previous Gurwitsch scholarship.  相似文献
