Langue française - Année 1997 - Volume 113 - Numéro 1 - Pages 79-91B. CONEIN : Multiple descriptions and object categorization Little research has yet been done, except in theory of perception, on the multiple ways physical objects are represented when they are used. By showing how the same object affords several various descriptions that capture diverse components of its use, Marr shed light on the semantic role of intermediary representations. This analysis shows when an object is used, visual properties are represented in a specific way without requiring object recognition and object naming. 13 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
