Egocentric and Allocentric Reference Frames Can Flexibly Support Contextual Cueing [PDF]
We investigated if contextual cueing can be guided by egocentric and allocentric reference frames. Combinations of search configurations and external frame orientations were learned during a training phase.

Postural adaptation of the spatial reference frames to microgravity: back to the egocentric reference frame. [PDF]
BACKGROUND: In order to test how gravitational information would affect the choice of stable reference frame used to control posture and voluntary movement, we have analysed the forearm stabilisation during sit to stand movement under microgravity ...

Cognitive load in switching between egocentric and allocentric spatial frames of reference: a pupillometry study [PDF]
Every day we combine and switch between body-centered (egocentric) and object-centered (allocentric) spatial representations. Several studies so far have reported a greater difficulty to switch from an allocentric reference frame to an egocentric one ...

Egocentric Dominance in Spatial Representations: The Role of Environmental Familiarity in Building Cognitive Maps [PDF]
Background Mental representations of spatial layouts and object locations are essential for building cognitive maps, which primarily rely on allocentric and egocentric reference frames. However, it remains unclear which reference frame individuals prefer

The neural basis of the egocentric and allocentric spatial frame of reference [PDF]
The present study examines the functional and anatomical underpinnings of egocentric and allocentric coding of spatial coordinates. For this purpose, we set up a functional magnet resonance imaging experiment using verbal descriptions of spatial relations either with respect to the listener (egocentric) or without any body-centered relations ...

The Simon effect based on the egocentric and allocentric reference frame [PDF]
The classic Simon effect refers to the phenomenon that responses are faster when the task-irrelevant egocentric stimulus location is on the same side as the response hand than when not. However, the spatial location of an object often varies according to which reference frame the object location was represented in, e.g., egocentric versus allocentric ...

Egocentric Spatial Memory Deficit in Amnestic Mild Cognitive Impairment Revealed Through Virtual Reality: Cross-Sectional Study [PDF]
BackgroundSpatial navigation relies on egocentric and allocentric frames of reference, with the latter critically impaired in Alzheimer disease (AD) due to hippocampal involvement.

An object’s location can be represented either relative to an observer’s body effectors (egocentric reference frame) or relative to another external object (allocentric reference frame).

Egocentric and allocentric spatial reference frames in aging: A systematic review
Aging affects many aspects of everyday living, such as autonomy, security and quality of life. Among all, spatial memory and spatial navigation show a gradual but noticeable decline, as a result of both neurobiological changes and the general slowing down of cognitive functioning. We conducted a systematic review using the Preferred Reporting Items for

Allocentric and egocentric reference frames in the processing of three-dimensional haptic space [PDF]
The main goal of our study is to gain insight into the reference frames involved in three-dimensional haptic spatial processing. Previous research has shown that two-dimensional haptic spatial processing is prone to large systematic deviations. A weighted average model that identifies the origin of the systematic error patterns in the biasing influence
