2005
Ce texte est un rapport de fin de recherche issu de l'ACI cognitique.; Ce projet avait pour objet d'apporter des éléments objectifs de réflexion sur les possibilités et limites de la perception et de la compréhension des matériaux et des structures d'une oeuvre de musique contemporaine. Les buts spécifiques comprenaient l'étude : 1) des processus d'invention et de résolution de problèmes dans la composition musicale, 2) des processus de traitement perceptif et de mémorisation des matériaux musicaux, 3) du traitement perceptif et mnésique des variations ou transformations opérées sur ces matériaux et de l'intégration des matériaux et de leurs transformations dans une forme d'ensemble, 4) du …
Identity dynamics and social partitions : the case of identity "racial" Blacks in France
2011
Our research work investigates - from a psycho-social point of view - the «racial» identity of the black population in France, notably in their relation with the white population, so as to point up the identity dynamics that exist between the various groups. The theoretical framework is related to social grouping and one of its developments, i.e. the concept of social partitioning. Such conception is based on the existence of several types of inter-category relations (partitioning) that allow apprehending the nature of individuals’ identity positioning within the framework of an inter-group relation and make it dynamic through the notion of co-construction. Our methodology is based mainly o…
Les aspects identitaires des biais de catégorisation sociale : le cas de la représentation de l'Europe.
2007
National audience; Le but de cette recherche est de mettre au jour, grâce aux lois de la catégorisation sociale, les dimensions identitaires pertinentes dans le cadre de l'Europe. A partir d'un dispositif amenant des sujets français à exprimer les liens affectifs qu'ils perçoivent entre Européens de différentes nationalités, on obtient par AFC une représentation de l'Europe opposant les pays occidentaux aux pays orientaux sur un premier axe et les pays ensoleillés aux pays froids sur un deuxième axe. La conformité à la réalité géographique est importante, les corrélations entre les axes subjectifs et les axes géographiques étant supérieures à 0,67 et étant significatives. Cependant, les bia…
Explicit and implicit tasks for assessing hedonic-versus nutrition-based attitudes towards food in French children
2015
Attitudes are important precursors of behaviours. This study aims to compare the food attitudes (i.e., hedonic- and nutrition-based) of children using both an implicit pairing task and an explicit forced-choice categorization task suitable for the cognitive abilities of 5- to 11-year-olds. A dominance of hedonically driven attitudes was expected for all ages in the pairing task, designed to elicit affective and spontaneous answers, whereas a progressive emergence of nutrition-based attitudes was expected in the categorization task, designed to involve deliberate analyses of the costs/benefits of foods. An additional exploratory goal was to evaluate differences in the attitudes of normal and…
Early-blind individuals show impaired performance in wine odor categorization
2018
International audience; Blind individuals display superior sensory abilities in other modalities, yet results remain contradictory regarding their performance on olfactory tasks. Using complex ecological olfactory tasks, we evaluated the impact of blindness on olfactory performance. We tested 12 early-blind individuals (M = 49, SD = 13.09) and 12 sighted controls (M = 49, SD = 14.31) who were all blindfolded. Based solely on the wine odors, participants evaluated 24 pairs of wine and determined if both samples belonged to the same category (red wine, white wine, or rosé wine) or not (odor categorization), and if so, whether they were identical or not (odor differentiation). Then, they had t…
The role of categorization bias in situations of sports and non-sport interaction among Cameroonian footballers migrating to Europe and the Maghreb
2019
The objective of this doctoral work was to consider the difficulties of integration of Cameroonian footballers migrating in Europe and the Maghreb. Starting from the mobilization of a theoretical framework centered on intergroup relations, we questioned the role ofcategorical and identity processes in situations of sporting and non-sporting interactions and their effects on players' behavior.The first exploratory and qualitative study was conducted among Cameroonian footballers who had lived an experience in European or Maghreb clubs. It highlighted the relationship difficulties and forms of discrimination sports and non-sporting which they face, in relation to their ethnic origin. The seco…
A psychosocial reading of sport actors’ antisocial behaviours : the influence of identity processes
2021
This doctoral work is interested in stakeholder’s antisocial behaviors. This phenomenon is approached by means of the theories bound to the social categorization, and more precisely, the social identity approach and the conception of the social partitions. Following this theoretical development, two mainstudies were led, the second one drawing from the first. A third study was led to reinject the acquired knowledge in the field.The first study, articulating around five sub-studies, aimed at determining the content, the perceived causes, as well as the perceived consequences, of sport stakeholders’ antisocial behaviors. Regarding the content of antisocial behaviors, harm and disadvantage asp…
Distinguishing between two crus : as easy as picking the right side ? : Effect of expertise on conceptual and perceptual representations of Beaujolai…
2017
Expertise was studied in cognitive psychology in order to understand the psychological mechanisms and the abilities involved in various areas of expertise. In the wine field, the few studies conducted on expertise suggest that the knowledge representation of experts is organized around “prototypes” derived from wines of different colours or grape varieties. The general purpose of this thesis was to address 1) theoretical questions about knowledge representation of wines among experts and novices, and 2) wine industry questions about Beaujolais wine perceptions. To this end, the effect of expertise on knowledge representations of wines was evaluated by comparing the performance of three diff…

2017
L’expertise a été étudiée en psychologie cognitive afin de comprendre les mécanismes psychologiques et les compétences intervenant dans différents domaines d’expertise. Dans le domaine du vin, les quelques études menées suggèrent que les experts organiseraient leurs connaissances autour de « prototypes » de couleur ou de cépage. L’objectif général de cette thèse visait à répondre aux questionnements théoriques concernant les représentations des vins d’experts et de novices, ainsi qu’aux questionnements de la filière concernant les perceptions des vins du Beaujolais. Pour cela, l’effet de l’expertise sur les représentations des vins a été évalué en comparant les performances de trois panels …
The role of sociales identities in the social representation of the fatigue in France and Syrie
2015
For a few years, many factors, such as the burden of training, are considered to be linked to the athletes’ difficulties to get used to training. The fatigue is one of the perceived problems by the athletes. Physiologically, the fatigue can be defined as “the decrease of a muscle’s capacity over time to exert force or power during a given exercise”. However, from the social point of view, the interpretation of fatigue is different and varies according to the social groups. This representation of the fatigue, specific to each group, should be considered as “a form of knowledge, socially developed and shared. In this doctoral thesis, we focus on the representation of fatigue in France and in …
