Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and 3 went further to demonstrate paradoxical unconscious priming effects resulting from task context. For example, after repeated practice classifying 73 as larger (...) than 55, the novel masked prime 37 paradoxically facilitated the “larger” response. In these experiments task context could induce subjects to unconsciously process only the leftmost masked prime digit, only the rightmost digit, or both independently. Across 3 experiments, subliminal priming was governed by both task context and long-term semantic memory. (shrink)

Chacun d'entre nous fait partie du monde, certes. Mais, au-delà de son évidence, quelle est la signification d'une telle formule? Comment faisons-nous partie du monde? Comment sommes-nous reliés à tout ce qui n'est pas nous : les autres, le reste de la nature, le cosmos? Lionel Naccache répond à cette énigme intemporelle à partir d'une approche mathématique fondée sur la distinction entre ensembles discrets et ensembles continus : alors qu'un élément, qui fait partie d'un ensemble discret, reste séparé des (...) autres éléments par des frontières tranchées, ces frontières disparaissent dans un ensemble continu. La question devient alors : sommes-nous reliés au reste du monde par des liens continus ou par des liens discrets? Muni de cette boussole, Lionel Naccache nous propose une odyssée passionnante et pleine de gai savoir éclectique qui nous entraîne de la psychologie de la subjectivité vers les sciences du cerveau et de la conscience, les origines et l'évolution des idées mathématiques et la philosophie politique. Au bout du voyage, Lionel Naccache formule une nouvelle éthique pour le XXIe siècle"--Page 4 of cover. (shrink)

This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major empirical observations that any theory of consciousness should incorporate, namely (1) a considerable amount of processing is possible without consciousness, (2) attention is a prerequisite of consciousness, and (3) consciousness is required for some specific cognitive tasks, including those that require durable information maintenance, novel combinations of operations, or the spontaneous generation of intentional (...) behavior. We then propose a theoretical framework that synthesizes those facts: the hypothesis of a global neuronal workspace. This framework postulates that, at any given time, many modular cerebral networks are active in parallel and process information in an unconscious manner. An information becomes conscious, however, if the neural population that represents it is mobilized by top-down attentional amplification into a brain-scale state of coherent activity that involves many neurons distributed throughout the brain. The long-distance connectivity of these `workspace neurons' can, when they are active for a minimal duration, make the information available to a variety of processes including perceptual categorization, long-term memorization, evaluation, and intentional action. We postulate that this global availability of information through the workspace is what we subjectively experience as a conscious state. A complete theory of consciousness should explain why some cognitive and cerebral representations can be permanently or temporarily inaccessible to consciousness, what is the range of possible conscious contents, how they map onto specific cerebral circuits, and whether a generic neuronal mechanism underlies all of them. We confront the workspace model with those issues and identify novel experimental predictions. Neurophysiological, anatomical, and brain-imaging data strongly argue for a major role of prefrontal cortex, anterior cingulate, and the areas that connect to them, in creating the postulated brain-scale workspace.

Can we ever experimentally disentangle phenomenal consciousness from the cognitive accessibility inherent to conscious reports? In this commentary, we suggest that (1) Block's notion of phenomenal consciousness remains intractably entangled with the need to obtain subjective reports about it; and (2) many experimental paradigms suggest that the intuitive notion of a rich but non-reportable phenomenal world is, to a large extent illusory – in a sense that requires clarification.

This article contributes to the general literature on the relationship between corporate social performance and corporate financial performance, as well as to the emerging HRM–CSR literature, by exploring the curvature of the relationship between HRM–CSP and CFP. We advance conceptual arguments in favor of an inverted U-shaped relationship. Our results demonstrate a significant quadratic relationship between HRM–CSP and CFP. We provide evidence that this relationship is not linear or S-shaped but rather inverted U-shaped.

This paper presents a non-reductionist framework of eight nested modes of evolution that have successively emerged to organize the reproduction of all organisms, from the blue-green algae to our societies. The processes of biological, "Darwinian," evolution are those of drift during reproduction, and of selection. The key unit of evolutionary time is the generation, and its locus is the organisms' life-cycle setup. Different life-cycle setups support different mechanisms of reproduction, and therefore different modes of evolution. By tracing the different life-cycle (...) setups attested throughout Life's History, we are able to characterize the successive modes of evolution with which they are associated. The present attempt has led to a characterization of the following eight nested modes of evolution: Basic; Reptilian; Archaic Mammalian; Progressive Mammalian; Socio-cultural; Extrasomatically Enhanced Socio-cultural; Tinkering; and finally Para-biological. These successively emerging modes govern a progressively reduced number of life-forms. The first four modes are "Darwinian" in the strict sense. The fifth, or socio-cultural mode, which governs whale and elephant societies in addition to hominoids, is already not "Darwinian" in the traditional sense. The last three modes have emerged with the genus homo, through the progressive extension of its life-cycle setups. The present framework is to be used heuristically, as a prism with which to separate the evolutionary spectrum of the constituent elements of human behavior. An example of such a behavioral evolutionary spectrum is presented in the conclusion, and is used to compare the present framework with those recently proposed by Maynard Smith and Szathmáry and by Foley.

First published in 1962, contains the William James Lectures delivered at Harvard University in 1955. It sets out Austin's conclusions in the field to which he directed his main efforts for at least the last ten years of his life. Starting from an exhaustive examination of his already well- known distinction of performative utterances from statements, Austin here finally abandons that distinction, replacing it by a more general theory of 'illocutionary forces' of utterances which has important bearings on a wide (...) variety of philosophical problems.

It was proposed that the data from Monte Carlo statistical investigations be subjected to analysis of variance methods rather than the conventional techniques of tabling, graphing, and inspecting the data. Two examples in which analysis of variance methods were applied to published Monte Carlo studies were presented. It was suggested that balanced factorial designs should be used whenever possible in Monte Carlo studies so that analysis of variance methods would be directly applicable. Finally, three advantages of analysis of variance methods (...) over conventional techniques were described and analysis of variance methods were contrasted with a possible alternative analytical method, multiple regression analysis.

Amidst the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of those dissenting results. On the basis of a minimal neuro-computational model, the global neuronal workspace hypothesis, we propose a (...) taxonomy which distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with a sudden surge of parieto-frontal activity causing top-down amplification.

This chapter defends the property dualism argument. The term “semantic premise” mentioned is used to refers to an assumption identified by Brian Loar that antiphysicalist arguments, such as the property dualism argument, tacitly assume that a statement of property identity that links conceptually independent concepts is true only if at least one concept picks out the property it refers to by connoting a contingent property of that property. It is argued that, the property that does the work in explaining the (...) possibility of a posteriori identities need not be a first-order property of the referent in question. On his view, the property dualism argument requires only a weaker semantic premise, which allows that the property in question be a higher order property. A refined version of the property dualism argument is formulated, which uses the weaker premise, and defends the argument against various objections. (shrink)

Current sociological theories appear to have lost their general persuasiveness in part because, unlike the theories of the ‘classical era’, they fail to maintain an integrated stance toward society, and the practical role that sociology plays in society. The authors explore various facets of this failure and possibilities for reconstructing sociological theories as integrated wholes capable of conveying a moral and political immediacy. They discuss the evolution of several concepts (for example, the social, structure, and self) and address the significant (...) disputes (for example, structuralism versus humanism, and individual versus society) that have dominated twentieth-century sociological thought. Their ideas and analyses are directed towards an audience of students and theorists who are coming to terms with the project of sociological theory, and its relationship with moral discourses and political practice. The authors of these essays are sociological theorists from the United States, the United Kingdom and Canada. They are all established, but not ‘establishment’ authors. The book contains no orthodoxies, and no answers. However, the essays do contribute to identifying the range of issues that will constitute the agenda for the next generation of sociological theorists. (shrink)
