Learning allocentric representations of space for navigation

Neurocomputing, 2021
Abstract The hippocampus of the mammalian brain supports spatial navigation by building cognitive maps of the environments in which the animal explores. Currently, there is little neurocomputational work investigating the encoding and decoding mechanisms of hippocampal neural representations in large-scale environments.

Time course of allocentric decay, egocentric decay, and allocentric-to-egocentric conversion in memory-guided reach

Neuropsychologia, 2011
Allocentric cues can be used to encode locations in visuospatial memory, but it is not known how and when these representations are converted into egocentric commands for behaviour. Here, we tested the influence of different memory intervals on reach performance toward targets defined in either egocentric or allocentric coordinates, and then compared ...

Allocentric coding: Spatial range and combination rules

Vision Research, 2015
When a visual target is presented with neighboring landmarks, its location can be determined both relative to the self (egocentric coding) and relative to these landmarks (allocentric coding). In the present study, we investigated (1) how allocentric coding depends on the distance between the targets and their surrounding landmarks (i.e.

Allocentric representations of space in the hippocampus

Neuroscience Research, 2020
The hippocampal-entorhinal system is essential for navigation and memory. The first description of spatially tuned place cell activity in area CA1 of the hippocampus suggested that spatial representations are not centered on self, but are rather allocentric.

Allocentrism and Perceptions of Helping

Journal of College Student Psychotherapy, 2000
Abstract This study applied Brickman, Rabinowitz, Karuza, Coates, Cohn, and Kidder's (1982) models of helping and coping to an allocen-trism-idiocentrism framework. The main hypothesis was that the model endorsed would depend upon the level of acculturation.

A study on the independence of egocentric and allocentric neglect

Cortex, 2017
Currently there seems to be consensus that visuospatial neglect may involve egocentric and allocentric symptoms. However, the relation between the two is still discussed and models have been proposed based on the high correlation between allocentric and egocentric neglect symptoms.

Creativity and Allocentric Perception

Perceptual and Motor Skills, 1966
Seven tests were used to measure allocentric-autocentric perception. The Remote Associates Test was used for selection of high, moderate and low creative female Ss. Intelligence was controlled and differences on WAIS subtest scores were examined. A consistent rank order was obtained among groups and Ss for the hypothesized construct.

Putting Egocentric and Allocentric into Perspective

2010
In the last decade many studies examined egocentric and allocentric spatial relations. For various tasks, navigators profit from both kinds of relations. However, their interrelation seems to be underspecified. We present four elementary representations of allocentric and egocentric relations (sensorimotor contingencies, egocentric coordinate systems ...

Allocentric and Egocentric Updating of Spatial Memories.

Journal of Experimental Psychology: Learning, Memory, and Cognition, 2004
In 4 experiments, the authors investigated spatial updating in a familiar environment. Participants learned locations of objects in a room, walked to the center, and turned to appropriate facing directions before making judgments of relative direction (e.g., "Imagine you are standing at X and facing Y.
