In the last decade many studies examined egocentric and allocentric spatial relations.
This work is meant to clarify concepts of egocentric and allocentric, to show their limitations, benefits and empirical plausibility and to point out new directions for future research. (2010) Putting Egocentric and Allocentric into Perspective.
This chapter discusses a new model of spatial memory and updating.
However, their interrelation seems to be underspecified.
We present four elementary representations of allocentric and egocentric relations (sensorimotor contingencies, egocentric coordinate systems, allocentric coordinate systems, and perspective-free representations) and discuss them with respect to their encoding and retrieval.
Among the different types of spatial processing, the allocentric, relying on the hippocampal formation, and the egocentric-updated, relying on parieto-temporal connections have both been considered to functionally underlie episodic memory encoding and retrieval.
We explore the cerebral correlates underlying the episodic retrieval of words previously learnt outside the magnet while performing different spatial processes, allocentric and egocentric-updated. Recognition memory: a review of the critical findings and an integrated theory for relating them.
Subjects in a darkroom saw an array of five phosphorescent objects on a circular table and, after a short delay, indicated which object had been moved.
During the delay the subject, the table or a phosphorescent landmark external to the array was moved (a rotation about the centre of the table) either alone or together.
When an animal moves from one place to another and turns from one direction to another, the spatial relationship between the animal and its environment changes constantly. Time-courses of memory decay in vector-based and landmark-based systems of navigation in desert ants, Cataglyphis fortis.
Spatial updating refers to the cognitive process that computes the spatial relationship between an animal and its surrounding environment as it moves based on perceptual information about its own movements. Journal of Comparative Physiology A-Sensory Neural & Behavioral Physiology, 181, 13-20.
Subsequently and during f MRI, participants performed an episodic word recognition task.
