    What do we know about the history of John Broadus Watson’s behaviorism outside of its American context of production? In this article, using the French example, we propose a study of some of the actors and debates that structured this history. Strangely enough, it was not a “classic” experimental psychologist, but Pierre Naville (1904–1993), a former surrealist, Marxist philosopher, and sociologist, who can be identified as the initial promoter of Watson’s ideas in France. However, despite Naville’s unwavering commitment to behaviorism, his weak position in the French intellectual community, combined with his idiosyncratic view of Watson’s work, led him to embody, as he once described himself, the figure of “the damned behaviorist.” Indeed, when Naville was unsuccessfully trying to introduce behaviorism into France, alternative theories defended by philosophers such as Jean-Paul Sartre and Maurice Merleau-Ponty explicitly condemned Watson’s theory and met with rapid and major success. Both existentialism and phenomenology were more in line than behaviorism with what could be called the “French national narrative” of the immediate postwar. After the humiliation of the occupation by the Nazis, the French audience was especially critical of any deterministic view of behavior that could be seen as a justification for collaboration. By contrast, Sartre’s ideas about absolute freedom and Merleau-Ponty’s attempt to preserve subjectivity were far more acceptable at the time

    La tentation psychobiographique. Autour des archives de Marie Bonaparte

    Get PDF
    La récente publication de la volumineuse correspondance entre Sigmund Freud et Marie Bonaparte a mis en lumière l’importance des archives de cette dernière. De Paris à Washington, en passant par le Texas, ce sont des dizaines de mètres linéaires qui sont aujourd’hui disponibles. Il ne s’agit pas seulement de textes techniques liés à sa production scientifique, mais aussi et surtout, de documents biographiques : lettres, journaux intimes et productions enfantines. Cette pionnière française de la psychanalyse et adepte convaincue de l’approche psychobiographique nous a en effet légué tout le matériel nécessaire pour que l’on se penche sur sa vie psychique intime. Malgré tout l’intérêt de cette démarche, cet article invite à ne pas céder trop rapidement à cette tentation psychobiographique, et à considérer ses archives comme un construit plutôt que comme un témoignage brut

    On the role of chirality in structure-odor relationships

    The influence of chirality on odors was studied on 16 enantiomeric pairs according to the dispersion/hydrogen bonding theory of receptor-odorant interaction. Comparisons of molecular structures were made by superimposition of optimized conformations, using the Alchemy II package. The quality of fit was assessed using the RMS parameter included in Alchemy II and a new index for hydrogen bonding: the angle between H-bonds in the two molecules. In the case of camphoraceous odorants where an interaction model was already known superimposition according to the model led to correct predictions of the high similarity of odors observed in enantiomeric pairs. For several urinous odorants comparisons were made using d-androstenone as a reference compound for the urinous odor. Correct predictions were obtained for l-androstenone, both enantiomers of androsta-4, 16-dienone, and (+)-2-methyl-4-(5,5,6-exo-trimethy1-2-exonorbornyl)-cyclobexane. The (−) enantiomer of the latter compound was correctly predicted only if it was assumed that its weak intensity is due to a partial interaction with the hydrophobic zone of the receptor. For ambergris odorants which have a complex odor (−)-Ambrox was selected as the reference compound. The odors of (+)-Ambrox and enantiomers of four other compounds (ambergris or woody) were correctly predicted by superimposition. For nootkatone and three derivatives which have a grapefruit note for one enantiomer and a woody note for the other no models or reference compounds were available. The superimpositions were made between grapefruit enantiomers, on the one hand, and woody enantiomers on the other hand. Woody and grapefruit characters were correctly predicted in all cases. The limits of this approach based on molecular modelling are discusse

    Topical Review: Basic Psychological Needs in Adolescents with Chronic Pain—A Self-Determination Perspective

    Get PDF
    This topical review outlines the resilience pathway to adaptive functioning in pediatric pain within a developmental perspective. Self-Determination Theory proposes that the satisfaction of one’s basic psychological needs (for autonomy, relatedness, and competence) is crucial for understanding human flourishing and healthy development. However, the role of the basic psychological needs received little attention in a pediatric-pain population. Yet, we propose that need satisfaction may be a resilience factor and need frustration a risk factor, for living with chronic pain. In this topical review, we first discuss two major models that have been developed to understand pain-related disability: the fear-avoidance model of pain and the ecological resilience-risk model in pediatric chronic pain. Both models have been used with children and adolescents but do not include a developmental perspective. Therefore, we introduce Self-Determination Theory and highlight the potentially moderating and mediating role of the basic needs on pain-related disability in children and adolescents. Taken together, we believe that Self-Determination Theory is compatible with the fear-avoidance model of pain and the ecological resilience-risk model in pediatric chronic pain and may deepen our understanding of why some adolescents are able to live adaptively in spite of chronic pain

    A survey on parallel and distributed Multi-Agent Systems

    No full text
    International audienceSimulation has become an indispensable tool for researchers to explore systems without having recourse to real experiments. Depending on the characteristics of the modeled system, methods used to represent the system may vary. Multi-agent systems are, thus, often used to model and simulate complex systems. Whatever modeling type used, increasing the size and the precision of the model increases the amount of computation, requiring the use of parallel systems when it becomes too large. In this paper, we focus on parallel platforms that support multi-agent simulations. Our contribution is a survey on existing platforms and their evaluation in the context of high performance computing. We present a qualitative analysis, mainly based on platform properties, then a performance comparison using the same agent model implemented on each platform

    Abundance of Delta Resonances in 58Ni+58Ni Collisions between 1 and 2 AGeV

    Full text link
    Charged pion spectra measured in 58Ni-58Ni collisions at 1.06, 1.45 and 1.93 AGeV are interpreted in terms of a thermal model including the decay of Delta resonances. The transverse momentum spectra of pions are well reproduced by adding the pions originating from the Delta-resonance decay to the component of thermal pions, deduced from the high transverse momentum part of the pion spectra. About 10 and 18% of the nucleons are excited to Delta states at freeze-out for beam energies of 1 and 2 AGeV, respectively.Comment: 14 pages, LaTeX with 3 included figures; submitted to Physics Letters

    Stopping and Radial Flow in Central 58Ni + 58Ni Collisions between 1 and 2 AGeV

    Full text link
    The production of charged pions, protons and deuterons has been studied in central collisions of 58Ni on 58Ni at incident beam energies of 1.06, 1.45 and 1.93 AGeV. The dependence of transverse-momentum and rapidity spectra on the beam energy and on the centrality of the collison is presented. It is shown that the scaling of the mean rapidity shift of protons established for AGS and SPS energies is valid down to 1 AGeV. The degree of nuclear stopping is discussed; the IQMD transport model reproduces the measured proton rapidity spectra for the most central events reasonably well, but does not show any sensitivity between the soft and the hard equation of state (EoS). A radial flow analysis, using the midrapidity transverse-momentum spectra, delivers freeze-out temperatures T and radial flow velocities beta_r which increase with beam energy up to 2 AGeV; in comparison to existing data of Au on Au over a large range of energies only beta_r shows a system size dependence

    K^+ production in the reaction 58Ni+58Ni^{58}Ni+^{58}Ni at incident energies from 1 to 2 AGeV

    Full text link
    Semi-inclusive triple differential multiplicity distributions of positively charged kaons have been measured over a wide range in rapidity and transverse mass for central collisions of 58^{58}Ni with 58^{58}Ni nuclei. The transverse mass (mtm_t) spectra have been studied as a function of rapidity at a beam energy 1.93 AGeV. The mtm_t distributions of K^+ mesons are well described by a single Boltzmann-type function. The spectral slopes are similar to that of the protons indicating that rescattering plays a significant role in the propagation of the kaon. Multiplicity densities have been obtained as a function of rapidity by extrapolating the Boltzmann-type fits to the measured distributions over the remaining phase space. The total K^+ meson yield has been determined at beam energies of 1.06, 1.45, and 1.93 AGeV, and is presented in comparison to existing data. The low total yield indicates that the K^+ meson can not be explained within a hadro-chemical equilibrium scenario, therefore indicating that the yield does remain sensitive to effects related to its production processes such as the equation of state of nuclear matter and/or modifications to the K^+ dispersion relation.Comment: 24 pages Latex (elsart) 7 PS figures to be submitted to Nucl.
