The role of egocentric-updating in episodic memory.

allocentric and egocentric updating of spatial memories-61

This is interpreted as evidence that object-to-object (allocentric) relationships play a large part in the human spatial updating system.

However, there was also some evidence that represented object directions occasionally drifted off of their true directions independently of one another, suggesting a lack of allocentric influence.

Human spatial representations of object locations in a room-sized environment were probed for evidence that the object locations were encoded relative not just to the observer (egocentrically) but also to each other (allocentrically).

Participants learned the locations of 4 objects and then were blindfolded and either (a) underwent a succession of 70° and 200° whole-body rotations or (b) were fully disoriented and then underwent a similar sequence of 70° and 200° rotations.

The manuscript is based on Jimmy Zhong’s Master’s thesis, conducted at the under grant ONR-N000140611072.

We thank Olesya Blazhenkova for her help in designing and conducting the experiments.

It has thus been proposed that during retrieval, disparate neocortical elements could be re-associated into a coherent episode due to an allocentric spatial representation (i.e., coding for object-to-object relations, independently of the individual's position) maintained within the hippocampal formation (Burgess, Becker, King, & O'Keefe, 2001, Nadel & Moscovitch, 1998).

However, in apparent discrepancies with a pure allocentric coding, the phenomenological experience is characterised by an autonoetic consciousness occurring while the original first perspective view on the original event is rein- stated.

However, the latter is simply too empowering and is not suitable as a “map in the head”.
