Besides the application of the notion of complementarity to psychological and physical descriptions of the individual, this paper explores the possibility of defining complementary observables in the same phenomenal domain. Complementary emotional observables are defined from experimental data on experienced emotions reported by subjects who have been prepared in a state of induced emotion. Complementary physiological observables are defined in correspondence with conjugate, physiological quantities that can be measured. -/- Keywords: Complementarity, Psychophysics, Emotional observables, Induced emotion, Physiological observables, Conjugate physiological (...) quantities.

Ce livre a pour objet d’évaluer l’apport de la physique quantique à l’explication du phénomène de la conscience. Après un état des lieux d’ordre sémantique, philosophique et neurobiologique de la question de la relation entre cerveau et conscience, les principaux modèles « classiques » actuels de la conscience sont exposés. Nous montrons que ces modèles laissent en suspens deux questions importantes : a) celle d’expliquer la synchronisation quasi-instantanée de régions éloignées du cerveau qui semble nécessaire à la constitution de percepts (...) conscients; b) celle du fossé explicatif qui existe entre l’expérience subjective, relevant de ce que le sujet est capable de ressentir de façon privée, et la description de ses corrélats neurophysiologiques dans le langage de la science, à la troisième personne – comment ces derniers « donnent-ils lieu » à l’expérience subjective?Les approches quantiques de la conscience plus récentes sont alors exposées de façon détaillée. Nous examinons dans quelle mesure elles peuvent contribuer à répondre à ces questions et proposer une représentation unificatrice intégrant les deux aspects psychique et physiologique du phénomène de conscience.

A Bell-type strategy of decision for the long-standing question of the nature of psychophysical correlations has been previously presented in a recent article published in Mind and Matter. This strategy of decision is here applied to experimental data on psychophysiological correlations, namely, correlations between cardiovascular and emotional variables that have been reported in several independent publications. This statistical analysis shows that a substantial majority of these correlations cannot be interpreted as an exchange of signals or a mere “interaction”, whatever its (...) form, but that these correlations could a priori be explained classically, as the result of a common preparation during the evolution process. A discussion on the scope and the limitations of this result will then be provided. In particular, alternative explanations of the psychophysical correlations that do not appeal to a notion of signalling will be discussed. (shrink)

This paper shows that the Clauser–Horne–Shimony–Holt test of locality of correlations which was originally designed to be used with binary observables can actually be used for any couples of quantum-like bounded continuous observables, and then for any experimental situation describable within the mathematical framework of quantum theory.

In this paper, we evaluate the project of resurgence of metaphysics based on the pecularity of the quantum domain, a project that is supported by some contemporary philosophers. Beyond the general arguments against scientific realism that are still applicable here, we show that this project is faced with the three following issues that, we believe, make it unrealizable: (a) the problem raised by the realistic interpretation of the wave function, as a description of a ‘concrete physical fact’ of the independent (...) reality; (b) the lack of any experimental counterpart of the (non-local) hidden variables quantum theories, and, in some cases, their incompatibility with the quantum predictions; and (c) the fact that the key-properties of quantum phenomena, like their non-locality, essentially depend on the observables that are used for their description and cannot then be assigned to any ‘independent’ reality.

All the attempts to find the justification of the privileged evolution of phenomena exclusively in the external world need to refer to the inescapable fact that we are living in such an asymmetric universe. This leads us to look for the origin of the “arrow of time” in the relationship between the subject and the world. The anthropic argument shows that the arrow of time is the condition of the possibility of emergence and maintenance of life in the universe. Moreover, (...) according to Bohr’s, Poincaré’s and Watanabe’s analysis, this agreement between the earlier-later direction of entropy increase and the past-future direction of life is the very condition of the possibility for meaningful action, representation and creation. Beyond this relationship of logical necessity between the meaning process and the arrow of time the question of their possible physical connection is explored. To answer affirmatively to this question, the meaning process is modelled as an evolving tree-like structure, called “Semantic Time”, where thermodynamic irreversibility can be shown. (shrink)

The quantum-like approach of psychosomatic phenomena suggests an explanation of the correlations between mind and body in terms of quantum-like entanglement, that is, without appealing to any concept of psychophysical, efficient causality. This approach is developed within the Hilbert space formalism and its general consequences are drawn. It is first illustrated by a simple, qualitative model of the placebo effect which shows that representing psychosomatic states by entangled states can explain that purely psychological factors can produce a-causal changes of physiological (...) parameters. Then, a dynamical, quantitative and predictive model of bipolar disorder which makes use of the unitarity of the temporal evolution of psychosomatic states due to biological and psychological rhythms is worked out. This model can explain some current observations, like for example the severe fluctuations in mood between depression and mania, and it can forecast the moment of shifting. In addition, it justifies the efficiency of chronotherapy on theoretical basis. (shrink)

Bayes’ inference cannot reliably account for uncertainty in mental processes. The reason is that Bayes’ inference is based on the assumption that the order in which the relevant features are evaluated is indifferent, which is not the case in most of mental processes. Instead of Bayes’ rule, a more general, probabilistic rule of inference capable of accounting for these order effects is established. This new rule of inference can be used to improve the current Bayesian models of cognition. Moreover, it (...) should play an essential role in the search for artificial emotional intelligence.

This paper suggests an epistemic interpretation of Belnap’s branching space-times theory based on Everett’s relative state formulation of the measurement operation in quantum mechanics. The informational branching models of the universe are evolving structures defined from a partial ordering relation on the set of memory states of the impersonal observer. The totally ordered set of their information contents defines a linear “time” scale to which the decoherent alternative histories of the informational universe can be referred—which is quite necessary for assigning (...) them a probability distribution. The “historical” state of a physical system is represented in an appropriate extended Hilbert space and an algebra of multi-branch operators is developed. An age operator computes the informational depth of historical states and its standard deviation can be used to provide a universal information/energy uncertainty relation. An information operator computes the encoding complexity of historical states, the rate of change of its average value accounting for the process of correlation destruction inherent to the branching dynamics. In the informational branching models of the universe, the asymmetry of phenomena in nature appears as a mere consequence of the subject’s activity of measuring, which defines the flow of time-information.

Due to the failure of the classical principles of bivalence and verifunctionality, the logic of experimental propositions relative to quantum systemscannot be interpreted in Boolean algebras. However, we cannot say neither that this logic is captured by orthomodular lattices, as claimed by many authors along the line of Birkhoff‘s and von Neumann‘s standard approach. For the alleged violation of distributivity is based on the possibility of combining statements relative to complementary contexts, which does not refer to any experience and, consequently, (...) has no meaning. Indeed, quantum logic should be interpreted in partial, transitive Boolean algebras whose compatibility relation limits the application of the connectives within each of its Boolean sub-algebras, which refer to partial, classical descriptions. Moreover, this approach of quantum logic makes it possible to deal with composite systems, which was not possible to do within the standard approach, and then to deal with the fundamental notion of quantum entanglement. The latter notion can be represented by a series of axioms of the object language that restrict the set of experimental statements bearing on a composite system, while its close link to the notion of complementarity can be expressed in the metalanguage.

This article deals with the difficulties of the yet intuitive causal interpretation of the mind–body connection emphasized by metaphysical, theoretical and experimental considerations. It shows that a decisive contribution to determining the nature of this connection can be provided experimentally. This experimental test is designed within the framework of a general systems theory capable of representing the concepts of complementarity and entanglement that are involved in the description of the mind–body connection.

Le lien entre physique et information est analysé et les limites conceptuelles et techniques de l’utilisation de la notion statistique d’information (-connaissance) en physique sont mises en évidence. Nous montrons que ces problèmes peuvent être résolus de façon satisfaisante en utilisant une notion d’information structurelle dont la mesure nous est donnée en terme de complexité algorithmique. Ce qui rend alors possible la construction d’une véritable « thermodynamique » de l’information fondée sur le concept d’information structurelle.

Abstract: The relationship between physics (...) and information is explored and the conceptual and technical limitations of the use of the notion of statistical information(-knowledge) in physics are emphasised. It is shown that these issues can be satisfactorily resolved by using a notion of structural information, the measure of which is provided in terms of algorithmic complexity. This makes possible the construction of a genuine “thermodynamics”. (shrink)
