Les cinq sens entre Moyen Âge et Renaissance : enjeux épistémologiques et esthétiques
2016
International audience; Ouvrage issu du colloque éponyme qui s'est déroulé à l'Université de Bourgogne (Dijon) les 17 et 18 novembre 2011 dans le cadre du Centre pluridisciplinaire texte et culture (CPTC).Ce volume propose l'analyse de la place qu'occupent les cinq sens dans cette période de transition qui conduit du Moyen Âge à la Renaissance, soit les XVe et XVIe siècles. L'approche en est résolument interdisciplinaire et confronte la théologie, la littérature, les arts figurés et les sciences. Il s'agit d'apprécier les sens dans les modes de pensée et les représentations, ainsi que leurs 'balances' : la vue, l'ouïe et les sens réputés moins nobles, comme le goût, l'odorat et le toucher, …

Is Sensation Seeking Linked Only to Personality Traits? The Role of Quality of Attachment in the Development of Sensation Seeking among Italian Adole…
2015
Considering sensation seeking as a personality trait has led to the driving of a series of studies on the biological and temperamental characteristics of sensation seekers. Conversely, from a bio-psychosocial perspective, personality factors are believed to account for about half of the likelihood that an individual will engage in disadaptive and dangerous actions, whereas environmental factors, such as primary relationships, interact with the person’s biology and affect the extent to which genetic factors exert their influence. On the light of these considerations, the present study explored the unique and common contributions of temperament and quality of attachment measured from 15 years…
Utilisation de la Dominance temporelle des sensations pour la caractérisation sensorielle des produits de la filière blé-farine-pain
2012
Eurogerm is specialized in flour correctors, bread improvers and technological ingredients for the wheat, flour and bread sector. The company gives great importance to sensory analysis as a diagnostic tool of finished products and has four expert panels; each panel is specialized in one category of products and is trained to standard sensory profiling. Today, in addition to the traditional method, Eurogerm wants to explore new methods in order to offer new services to its customers. This paper describes the development of Temporal Dominance of Sensations (TDS) created in the “Centre des Sciences du Goût et de l’Alimentation” (CSGA) (PINEAU et al., 2009). TDS provides information on the perc…
De la perception sensorielle à la consommation du vin. Partie 1/2 : Mécanisme de la perception sensorielle : reflet de la réalité
2010
National audience; Afin de percevoir son environnement et de pouvoir réagir en conséquence, l’être humain est équipé de capteurs sensoriels. Ces capteurs constituent une interface entre le sujet et le monde extérieur et quelle que soit la stimulation extérieure, ils mettent en jeu les mêmes mécanismes sensoriels. Lorsque les capteurs sensoriels rentrent en contact avec un stimulus, les informations engendrées sont amplifiées, puis transmises au système nerveux central sous forme de signaux électriques (Mac Leod et Sauvageot, 1986) après avoir été progressivement filtrées, réduites et stabilisées. Ces informations électriques sont caractérisées d’une part par une masse globale d’activité, co…
Fine adaptive control of precision grip without maximum pinch strength changes after median nerve mobilization
2020
ABSTRACTFine dexterity critically depends on information conveyed by the median nerve. While the effects of its compression and vibration are well characterized, little is known about longitudinal tension and excursion. Using a force-sensitive manipulandum, a numeric dynamometer and Semmes-Weinstein monofilaments, we examined the adaptations of precision grip control, maximum pinch strength and fingertips pressure sensation threshold before and immediately after the application of longitudinal tension and excursion mobilizations applied on the median nerve. Grip (GF) and load (LF) forces applied by the thumb, index and major fingers were collected in 40 healthy young participants during thr…
Psychophysical response to electrocutaneous stimulation.
1984
A method is presented to determine a reliable stimulus-sensation relationship particularly suitable for electrocutaneous stimulation. An experimental intensity-discrimination curve was obtained through simple psychophysical comparison tasks, and sensory response was inferred from integration of a JND's density function. The psychophysical response resembles a power law, although departures cannot be described in terms of a unique exponent. An estimate of binary information capacity per electrode is also given as a feature of a stimulation procedure that preserves a low value of the size-intensity product.
Factorial Structure and Psychometric Properties of the Sensation Seeking Scale – Form V (SSS-V) in a Sample of Italian Adolescents
2013
The present study was designed to evaluate the psychometric properties of the Sensation Seeking Scale – Form V (SSS-V) for the Italian-speaking population. The instrument was administered to 1,530 high school and college students. A second group of 268 high school students completed the SSS-V and the Impulsiveness Questionnaire (IVE). Exploratory factor analysis highlighted a 2-factor structure, Thrill and Adventure Seeking (TAS) and Disinhibition (Dis). Confirmatory factor analysis revealed an adequate model fit. Internal consistency of the subscales was marginally supported using the alpha reliability measure. Convergent validity was supported by significant positive correlations between …
Protons for Jehovah’s Witnesses? How press coverage of Ashya King’s case brought proton beam therapy to the public arena
2018
The case of Ashya King, the child brain tumour patient whose parents took from a British hospital so he could be treated with Proton Beam Therapy (PBT) abroad, contributed to popularize that technology among a general audience. Through the content analysis of British and Spanish press coverage (N=329), our research shows that proton therapy enjoyed scarce coverage in the analysed media before Ashya King’s case. His story, magnified due to the fact that his parents were Jehovah’s witnesses was a cause both for public concern and media sensationalism. We show that the case brought PBT into the public sphere and, consequently, contributed to create a demand for facilities that offered this the…
Individual characteristics associated with fat liking
2015
Introduction: Various studies have shown that sensory liking influences dietary behaviors and that individual characteristics, such as socio-demographic or psychological factors, are related to dietary intake and weight status. However, little is known about individual profiles associated with fat liking. Objectives: The aim of the present study was to investigate the associations between liking for fat sensation and socio-demographic, economic, psychological, lifestyle and health characteristics in a large sample of adults. Method / Design: Individual factors and liking scores were collected using validated questionnaires from 37,181 French adults participating in the NutriNet-Santé study,…
