Op art et roman virtuel : correspondances entre Escher et Perec
2012
Op art et roman virtuel : correspondances entre Escher et Perec Les structures mathématiques, la notion de réalité comme « humaine illusion », le défi à l’infini et la structure énigmatique qui donne aux œuvres eschériennes la même structure que celle d’un roman policier permettent d’établir des convergences significatives entre le graveur hollandais et Georges Perec. Dans certaines œuvres de Perec, en effet, il est possible de remarquer des références explicites au graveur bien qu’elles constituent la traduction visuelle de l’angoisse du « retour du semblable », du « retour involontaire au même point ». Mais Perec ne se limite pas seulement à citer Escher, puisque certaines de ses œuvres c…
Estudio del embodiment y las alteraciones de la integración multisensorial corporal y su papel en la psicopatología de los trastornos de la conducta …
2016
En los últimos años, ha habido un interés renovado sobre los estudios del cuerpo, fundamentalmente a través de las teorías del embodiment. Entre sus muchas definiciones, la experiencia del embodiment se describe específicamente como el sentido mediante el cual un individuo se localiza dentro de sus límites físicos de su propio cuerpo. Ese sentido de localización se complementa con el de auto-reconocimiento y propiedad corporal, que se conforman desde la integración de diversas señales sensoriales del cuerpo (ej., visión, tacto, propiocepción, etc.), junto con el sentido de la agencia del cuerpo, es decir, la conciencia subjetiva de que nosotros somos quienes ejecutamos y controlamos las acc…
Visually produced locomotion in an autokinetic setup.
1987
On individual ttials, 15 subjects stood G m before a minicomputer screen displaying a colon in a completely darkened room Subjects were aware that the light source wzs stationary. They were instructed to fixate the colon and to perform nonlocomotive jogging in place for 2 min. and continuously to report their sensations. Room lights were turned on after 30 sec., and subjects' deviations from their starting places were measured. All subjects had moved toward the light source (M = 4.42 m, SD = .43) although they were convinced that they had not moved. Instead, they had reported either the light source approached them or the light source became larger and/or more intense. On a second trial, su…
L’image des légumes
2017
Au sein du vaste champ de recherche qu’est l’alimentation, les légumes et les représentations qu'en ont les mangeurs ont été délaissés malgré la place importante qu'ils occupent dans les discours officiels depuis la mise en place en 2001 du PNNS. Dans un contexte de stagnation de leur consommation, il semble judicieux de tenter de comprendre quels en sont les freins. Notre hypothèse veut que les discours médiatiques sur le sujet, dans la lignée du discours des autorités publiques, présentent les légumes avant tout comme un aliment fonctionnel, dans un pays où le goût et le plaisir restent pourtant des piliers de la culture alimentaire. Pour mettre à l’épreuve ce postulat, notamment à traver…
O047. The sound-induced flash illusions reveal visual cortex hyperexcitability in cluster headache
2015
Objectives Pathophysiology of cluster headache (CH) is not wellknown. Although posterior hypothalamus has been suggested to play a pivotal role, evidence exists of a more diffuse involvement of the central nervous system including brainstem and cerebral cortex. In this regard, we recently observed increased motor cortical excitability in episodic CH patients both outside and inside bout [1]. The sound-induced flash illusions (SIFI) represent an example of multisensory integration, and provide a tool to indirectly explore the excitability state of the visual cortex [2]. SIFI are classified as “fission” and “fusion” illusions. When one visual stimulus (flash) is accompanied by two or more aud…
The illusion of contact: Insights from Winnicott’s 1952 letter to Klein
2021
Using Winnicott’s theory, this article produces an account of the individual’s relation to a given conceptual framework. Whereas Winnicott’s ideas have been almost exclusively discussed in developmental and psychopathological contexts, the present article extends Winnicott’s theory and applies it to the problem of interpersonal understanding. Taking a lead from one of Winnicott’s letters to Klein, the article investigates the problem of expressing one’s idiosyncratic insights in the confines of a given conceptual framework. The article examines Winnicott’s theory of compliance and creativity, discusses the plea that Winnicott makes to Klein, analyses the encounter with a “dead language”, an…
Oltre l'illusionismo pittorico: i teatrini prospettici nell'architettura siciliana tra Seicento e Settecento
2015
Durante i primi trentanni del XVI secolo l'uso in Sicilia di composizioni scultoree in prospettiva subì un significativo sviluppo grazie all'opera di Antonello Gagini (1478ca-1536) che conferì un vero e proprio effetto tridimensionale alle immagini scolpite nel marmo dando luogo ai cosiddetti "teatrini prospettici". L'inizio artistico di Giacomo Serpotta (1656-1732) diede il via ad una nuova, breve ma significativa fase orientata verso nuovi effetti prospettici. During the first thirty of the 16th century the use in Sicily of perspective compositions in sculptural reliefs underwent significanti development thanks to the work of Antonello Gagini (1478ca-1536) who passed previous models and l…

Full-body illusions and minimal phenomenal selfhood.
2008
We highlight the latest research on body perception and self-consciousness, but argue that despite these achievements, central aspects have remained unexplored, namely, global aspects of bodily self-consciousness. Researchers investigated central representations of body parts and actions involving these, but neglected the global and unitary character of self-consciousness, the ‘I’ of experience and behaviour. We ask, what are the minimally sufficient conditions for the appearance of a phenomenal self, that is, the fundamental conscious experience of being someone? What are necessary conditions for self-consciousness in any type of system? We offer conceptual clarifications, discuss recent e…
Unrealistic Optimism in the Time of Coronavirus Pandemic: May It Help to Kill, If So—Whom: Disease or the Person?
2020
Objective: The results of numerous empirical studies have showed the occurrence of so-called unrealistic optimism. Thus, we aimed to investigate whether in the situation of an imminent coronavirus pandemic, people would still perceive themselves as being less exposed to the disease than others. Methods: Survey studies were conducted to examine the level of unrealistic optimism. Participants (n = 171, 67.3% of women) in a subjective way judged the risk of their coronavirus infection and the likelihood that this would happen to an average student of the same sex from their class. The survey was conducted in three waves: prior to the announcement of the first case of coronavirus (2&ndash
