Using the matching bias example, the aim of the present studies was to show that adults' reasoning biases are due to faulty executive inhibition programming. In the first study, the subjects were trained on Wason's classical card selection task; half were given training in how to inhibit the perceptual matching bias (experimental group) and half in logic without the inhibition component (control group). On the pre- and post-tests, their performance was assessed on the Evans conditional rule falsification task (with a (...) negation in the antecedent of the rule), a task that also involves matching bias. In addition, subjects were tested for perceptual field dependence/independence using the Embedded Figures Test. The results brought out a specific inhibition training effect, as well as a clear-cut relationship in the experimental group between receptiveness to training and perceptual field independence. In the second study, the training paradigm was the same except that on the pre- and post-tests, the negation was in the consequent of the conditional rule (in this case, the perceptual matching response corresponds to the logical response). The subjects succeeded on the pre-test, and the matching-bias inhibition training had a negative effect on post-test performance. This specific negative priming effect confirms the inhibitory impact of our experimental training and outlines the dissociation of inhibition and logical components. (shrink)

Neuroconstructivism: How the Brain Constructs Cognition proposes a unifying framework for the study of cognitive development that brings together (1) constructivism (which views development as the progressive elaboration of increasingly complex structures), (2) cognitive neuroscience (which aims to understand the neural mechanisms underlying behavior), and (3) computational modeling (which proposes formal and explicit specifications of information processing). The guiding principle of our approach is context dependence, within and (in contrast to Marr [1982]) between levels of organization. We propose that three (...) mechanisms guide the emergence of representations: competition, cooperation, and chronotopy; which themselves allow for two central processes: proactivity and progressive specialization. We suggest that the main outcome of development is partial representations, distributed across distinct functional circuits. This framework is derived by examining development at the level of single neurons, brain systems, and whole organisms. We use the terms encellment, embrainment, and embodiment to describe the higher-level contextual influences that act at each of these levels of organization. To illustrate these mechanisms in operation we provide case studies in early visual perception, infant habituation, phonological development, and object representations in infancy. Three further case studies are concerned with interactions between levels of explanation: social development, atypical development and within that, developmental dyslexia. We conclude that cognitive development arises from a dynamic, contextual change in embodied neural structures leading to partial representations across multiple brain regions and timescales, in response to proactively specified physical and social environment.

L'une des tâches séculaires de la philosophie est de surmonter ce que Locke nommait l'abus des mots; le dictionnaire des ntions s'efforce de l'accomplir en présentant une technologie des réseaux sémantiques.

Bien que le thème de la volonté soit l’un des plus explorés depuis l’Antiquité tardive, le concept même du vouloir et le champ phénoménal qu’il désigne n’ont que rarement fait l’objet d’une recherche philosophique systématique, et, lorsque c’est le cas, comme chez Ricoeur ou Arendt, Schelling n’est pas suffisamment pris en considération. Tel est le constat dont part Philipp Höfele et qui justifie l’intérêt et l’importance de cette étude issue de sa thèse de doctorat. Le but de Höfele est donc...

This book provides a comprehensive commentary of the Philebus designed to shed light on the nature and function of the good in Plato’s philosophy as a whole. Topics discussed include dialectic, pleasure, epistemology, and the relations between metaphysics and ethics.

This paper presents a version of hylomorphism that intends to solve problems faced by contemporary hylomorphism. After showing that attempts to understand form as sets or relation of essential properties fail at taking into account the dynamic development of substances, the paper suggests another version of hylomorphism able to solve these difficulties. A functionalist version of hylomorphism is then defended: the best way to understand how form can be present throughout all the developmental stages of a substance is to understand (...) it as a certain kind of function.

This paper studies ‘minority’ initiatives to organize sports games. A meta-analysis of published data in the literature identifies the formal appearance taken by each of these initiatives under the Olympic model. But it also conduces to build a number of indicators to answer a series of questions about their logic and strategies. All the initiatives studied are based on an ambivalent posture that, while based on the denunciation of a discriminating space, claim access to it. By an astonishing paradox, ‘non-normative’ (...) actors are driven to reclaim a model that, under cover of Universal, aims to establish a norm that is situated and dated. In practice, they use two types of strategies: a strategy for participation in the Olympics to transform them into a space which represents a fight against exclusion, or a strategy to create alternative events. Whatever the strategy, these initiatives are implemented according to their objectives. Differentiated in their forms—participatory or autonomy—they are also in their purpose. The comparison of these initiatives shows that ultimately, beyond strategies and logic inherent in different social, historical and organizational contexts, the mobilizations of the actors reveal the same ambivalence about the sports model conveyed by the Olympic institution.

In this collection of essays, Bromberger explores the centrality of questions and predicaments they create in scientific research. He discusses the nature of explanation, theory, and the foundations of linguistics.

Intuitive predictions and judgements under uncertainty are often mediated by judgemental heuristics that sometimes lead to biases. Our micro-developmental study suggests that a presumption of rationality is justified for adult subjects, in so far as their systematic judgemental biases appear to be due to a specific executive-inhibition failure in working memory, and not necessarily to a lack of understanding of the fundamental principles of probability. This hypothesis was tested using an experimental procedure in which 60 adult subjects were trained to (...) inhibit the classical conjunction bias on a frequency judgement task derived from Tversky and Kahneman's work. Pre- and post-test performance was assessed via a probability judgement task. The data indicated a training effect, suggesting that subjects traditionally labelled as "irrational" with respect to the classical rules of inductive reasoning are in fact "inefficient inhibitors". These findings are discussed in terms of a polymorphous view of rationality. (shrink)

Fruit d'un colloque tenu en 2010 dans la ville de Budapest, cet ouvrage collectif introduit aux grands chapitres de l'oeuvre de l'académicien en même temps qu'elle lui adresse certaines questions permettant d'en mieux saisir les enjeux et d'en indiquer quelques prolongements possibles. Cartésianisme, phénoménologie et théologie : telles sont les trois voies thématiques empruntées afin d'interroger un travail qui a su se rendre indispensable à son époque.

This research investigates the potential for a “fair” co-branding operation. A major corporate brand is fictitiously allied with a Fair Trade labelling organization brand. The sample for the study is composed of 540 respondents, representative of the French population. By considering commercial brands and Fair Trade labels as dissimilar in terms of customers’ perceived Fair Trade orientations, this article studies how this lack of similarity impacts perceived congruence between both entities and how prior brand attitudes and congruence influence customers’ evaluation (...) of the co-branded product. The results of this research demonstrate that: Consumer prior brand attitudes toward the partner brands influence very little customers’ evaluation. Perceived similarity of the partner brands has a strong influence toward congruence of the co-branding operation. Results also indicate that congruence has a strong influence upon customers’ evaluation. An inverted U-shaped relationship exists between perceived similarity and relevancy of the alliance, and between expectancy and customers’ evaluation. The results obtained through the test of a partial least square model, and inverted U-shaped hypothesis, represent a new insight into co-branding theory. The high discursive power of fair co-branding is a key issue: the corporate brand provides the alliance with its leading position, while the Fair Trade brand provides the ethical attribute. (shrink)

Dans des écrits datant des années 1277-79, le théologien franciscain Pierre de Jean Olivi emploie à cinq reprise le mot averroista, pour critiquer, non pas tant la doctrine de l'unicité de l'intellect possible que ses implications anthropologiques ou angélologiques. Cette critique bien informée, convergente avec d'autres attaques franciscaines, notamment les dénonciations de Roger Bacon, démontre la réalité et l'ampleur d'une entreprise philosophique menée par des maîtres ès arts, s'inspirant d'Averroès, dans les années 1260-70 ; elle indique aussi la diversité de (...) leurs points de vue. Dès son apparition, il n'y a donc pas un, mais plusieurs 'averroïsmes' latin. (shrink)

"La grande question métaphysique aujourd'hui, en matière de langage, est de savoir si un modèle computationnel suffit à expliquer le comportement linguistique humain. Est-ce que la faculté de langage de chacun d'entre nous et plus spécialement sa compétence linguistique, s'explique parce que nous avons des algorythmes implémentés dans notre tête? Cette question appartient de plein droit à la philosophie de la linguistique. Elle a une vaste portée. En aval, elle concerne la représentation d'une bonne partie du comportement humain, selon le (...) modèle qu'en donnent les cognitivistes de stricte obédience. En amont, elle concerne tout simplement le vieux débat de théorie de la connaissance entre le rationalisme et l'empirisme. L'objet de ce livre est une critique fouillée du rationalisme dans ses fondements linguistiques. Il prend donc la forme d'une analyse de la nature du savoir linguistique et de celle du langage.... Il s'agit de constituer les bases d'une nouvelle version de l'empirisme que nous pouvons baptiser externalisme. Les résultats développés dans ce livre concernent principalement la théorie de la science et celle du langage. La thèse ultime de l'externalisme c'est que l'esprit lui-même est d'essence historique et empirique." Extrait de l'introduction. (shrink)

Robot programming by demonstration covers methods by which a robot learns new skills through human guidance. We present an interactive, multimodal RPD framework using active teaching methods that places the human teacher in the robot’s learning loop. Two experiments are presented in which observational learning is first used to demonstrate a manipulation skill to a HOAP–3 humanoid robot by using motion sensors attached to the teacher’s body. Then, putting the robot through the motion, the teacher incrementally refines the robot’s skill (...) by moving its arms manually, providing the appropriate scaffolds to reproduce the action. An incremental teaching scenario is proposed based on insights from various fields addressing developmental, psychological, and social issues related to teaching mechanisms in humans. Based on this analysis, different benchmarks are suggested to evaluate the setup further. (shrink)

Que dire des épreuves de la vie? Nous ne savons quelles elles sont qu'à les traverser et ignorons ce qu'elles sont en les endurant. Quand surviennent-elles? Comment? Et pourquoi? Aveugles lorsqu'elles frappent, hagards lorsqu'elles cessent, comment pourrions-nous porter sur elles nos regards? Dans l'obscure nuit qu'elles répandent sur nos vies, tout n'est cependant pas que ténèbres. Car les épreuves révèlent, elles phénoménalisent. Sous leur sombre lumière, tout se montre sous son vrai jour. Condamnés par le pire à donner le meilleur, (...) nous qui les essuyons faisons alors nos preuves. Dans l'épreuve, l'ego apparaît donc comme jamais il ne le fait, non pas comme il le doit, mais toujours comme il est. Faudrait-il ajouter que d'épreuves comme de phénoménologie, il n'en est que de la vie pour que l'idée d'une phénoménologie des épreuves de la vie s'impose en philosophie? Inutile : l'irrésistible réalité de ces épreuves impose à qui les subit un inextinguible besoin de philosophie. Or qui mieux que la phénoménologie peut, en philosophie, mettre à l'épreuve les épreuves de la vie. (shrink)

French student teachers are provided with initial training which sometimes offers them an analysis of the situations they may be confronted with when teaching in their classrooms. This research work focuses on a specific device : Training Groups Analysing Professional Practices. It consists in presenting the analysis group organizers’ opinion (collected from semi-structured interviews) as well as that of the student teachers (collected via self-administered questionnaires) during three school years. It also highlights the idea that the analysis of professional practices (...) sessions contribute to vocational training: these sessions aim at grasping the complexity of the act of teaching and they allow the student teachers to receive coaching in their first year of teaching.

For Merleau-Ponty and Maldiney, the world of the pictorial image is “an almost crazy world” and a world of “confused sensations”. However, it is not only an illusory and chimeric world, cut off from the real world. Indeed, far from distancing us from the real world, this craziness and this confusion bring us back to it. The objective of this essay is therefore to question the relationship between pictorial art and the real (not fictional or imaginary) world. Certainly, the pictorial (...) work of art makes us return “to the things themselves”, because it establishes a conversion of the gaze and a metamorphosis of the visible. But one can ask if this conversionof the gaze does not reverse the movement of phenomenological “reduction” as described by Edmund Husserl, since it plunges us into the very heart of the world and does not imply any abstention or abstraction. For Maldiney as for Merleau-Ponty, painting reveals our original being-in-the-world, so that it will be necessary to elucidate what it means exactly. Moreover, we will investigate the role of style and rhythm as well as the role of color and the line in order to describe more precisely the connection between the world and the work of art, between continuity and discontinuity. Finally, we will propose another meaning of the word “image”in order to highlight the ethical function of the image thus understood. (shrink)

During the course of evolution, variations of a protein sequence is an ongoing phenomenon however limited by the need to maintain its structural and functional integrity. Deciphering the evolutionary path of a protein is thus of fundamental interest. With the development of new methods to visualize high dimension spaces and the improvement of phylogenetic analysis tools, it is possible to study the evolutionary trajectories of proteins in the sequence space. Using the data-driven high-dimensional scaling method, we show that it is (...) possible to predict and represent potential evolutionary trajectories by representing phylogenetic trees into a 3D projection of the sequence space. With the case of the aminodeoxychorismate synthase, an enzyme involved in folate synthesis, we show that this representation raises interesting questions about the complexity of the evolution of a given biological function, in particular concerning its capacity to explore the sequence space.

En bref, nous pensons qu'un regard critique sur un passé parfois méconnu est un moyen d'ouvrir de nouvelles perspectives et de continuer, ainsi, de travailler avec Foucault.

Autour de 1100, pour les jeunes femmes de l’aristocratie éduquées dans des monastères, l’écriture de lettres d’amour fictives à leur maître de rhétorique constituait un apprentissage aussi bien littéraire qu’émotionnel. Comme le rappelle Barbara Newman, les Epistolae duorum amantium, correspondance échangée par Héloïse et Pierre Abélard durant leur liaison, doivent se comprendre dans cette lumière. Leur singularité tient largement au fait qu’Héloïse a choisi de donner corps à une figure poétique, en s’identifiant aux héroïnes tragiques d’Ovide.
