Note théorique : Influences des activités du sujet et des caractéristiques environnementales sur la nature de l’encodage spatial
Résumé
Since the concept of spatial cognitive map appeared, it has been shown that different parameters play a role in how spatial representations are encoded within ego- or allocentered frames of reference. The main influences seem to come on the one hand from the variations of the subject's activity and, on the other hand, from the nature of the configuration to be learned. Because we necessarily perceive space from our current position and orientation (ego), abstraction of this information into a more global bird's eye view (allo) involves cognitive processes. By this respect, moving and locating requires the subject to mentally connect different pieces of information built either within an ego or an allocentric spatial frame of reference. Some researchers have suggested that these two kinds of spatial frames of reference are used in parallel but nowadays, even if some studies have identified the specific influences of these different parameters, their coordination mechanisms still pose questions.
