Egocentric Dominance in Spatial Representations: The Role of Environmental Familiarity in Building Cognitive Maps [PDF]

Brain and Behavior
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

Cognitive load in switching between egocentric and allocentric spatial frames of reference: a pupillometry study [PDF]

Scientific Reports
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 and Allocentric Reference Frames Can Flexibly Support Contextual Cueing

Frontiers in Psychology, 2021
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.

The Impact of Vision Loss on Allocentric Spatial Coding

Frontiers in Neuroscience, 2020
Several works have demonstrated that visual experience plays a critical role in the development of allocentric spatial coding. Indeed, while children with a typical development start to code space by relying on allocentric landmarks from the first year ...

Distinct aging-related profiles of allocentric knowledge recall following navigation in an immersive, naturalistic, city-like environment [PDF]

Frontiers in Aging Neuroscience
Aging-related declines in spatial navigation pose significant challenges for older adults’ independence and quality of life. Among navigational deficits, older adults have been shown to demonstrate deficits in utilizing allocentric (i.e., world-centered)

The Simon Effect Based on Allocentric and Egocentric Reference Frame: Common and Specific Neural Correlates

Scientific Reports, 2019
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 Spatial Memory Deficit in Amnestic Mild Cognitive Impairment Revealed Through Virtual Reality: Cross-Sectional Study [PDF]

JMIR Aging
BackgroundSpatial navigation relies on egocentric and allocentric frames of reference, with the latter critically impaired in Alzheimer disease (AD) due to hippocampal involvement.

Navigating space and the developing mind [PDF]

Frontiers in Psychology
In this article, we review the extensive and complex fabric of literature concerning the ontogenesis of spatial representations from earliest childhood to the elderly, including normal and abnormal aging (dementia and Alzheimer’s disease).

Allocentric flocking [PDF]

Nature Communications
Understanding how group-level dynamics arise from individual interactions remains a core challenge in collective behavior research. Traditional models assume animals follow simple behavioral rules, like explicitly aligning with neighbors. We present here

Perception of distance during self-motion depends on the brain's internal model of the terrain. [PDF]

PLoS ONE
The body's geometrical relationship with the terrain is important for depth perception of human and non-human terrestrial animals. Static human observers in the dark employ the brain's internal model of the terrain, the intrinsic bias, to represent the ...
