Encodage spatial et intelligence

Abstract : The dissertation is organized in two parts. The first part presents the literature concerning the study of spatial cognition. This representation adopts an interdisciplinary approach (psychology, neurophysiology, information sciences, ethology, philosophy). Of special interest are interindividual differences in spatial cognition as described by these disciplines. Particular attention is payed to qualitative processing differences, i.e. different strategies for processing of visuo-spatial information. Individual differences in the quality of representations constructed from navigation in a threedimensional space are also analysed. The attempt is made to create an integrative framework of interpretation for the described differences on the basis of the neurologically plausible theory of Kosslyn introducing the distinction between categorical and metric spatial relations encoding. The hypothesis is made that the efficiency of these subsystems may represent an important element in the explanation of interindividual differences in spatial cognition. In the second part, 4 experiences are presented which imply the measurement of the quality of spatial relations encoding with computer-assisted tests. One of these tests measures specifically the precision of spatial relations encoding and shows stability of individual differences, as well as the relation between spatial relations encoding precision and performance on paper and pencil tests. This relation seems important, especially with the spatial and general factors of intelligence. A navigation test in a virtual environment furthermore permits to evaluate the influence of spatial relations encoding precision on wayfinding performance. Results are interpreted in the framework of Kosslyn's neurologically plausible theory of visuo-spatial information processing.
