Abstract EN:
The clinical and experimental study of a case of prosopagnosia shows the importance of the variables familiarity and context in facial recognition. A prosopagnosic patient (facial agnosia) is submitted firt to standards neuropsychological tests, then to detailed neuropsychological tests, at least he is submitted to a set of experimental tests of facial recognition. The used faces present differents degress of familiarity and are, for a part of them, associated with a context. The experimental study shows the critical role of the interaction "familiarity context", already seen in the clinical study.

L'etude clinique et experimentale d'un cas de prosopagnosie permet de mettre en evidence le role preponderant de la familiarite et du contexte dans la reconnaissance des visages. Un patient prosopagnosique (agnosie des visages) est d'abord soumis a un examen neuropsychologique standard, puis a un examen neuropsychologique detaille. Enfin, il est soumis a un protocole experimental de reconnaissance des visages qui presente differents degre de familiarite et qui peuvent etre ou non associes a un contexte. L'etude experimentale confirme le role critique de l'interaction familiarite et contexte, deja mise en evidence par l'etude clinique du cas
