Cognitive Load in Switching Between Egocentric and Allocentric Spatial Frames of Reference: A Pupillometry Study

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 ...

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

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)

A Critical Review of the Allocentric Spatial Representation and Its Neural Underpinnings: Toward a Network-Based Perspective

Frontiers in Human Neuroscience, 2014
While the widely studied allocentric spatial representation holds a special status in neuroscience research, its exact nature and neural underpinnings continue to be the topic of debate, particularly in humans.

How semantic context and temporal dynamics affect egocentric and allocentric spatial representations [PDF]

Scientific Reports
Pouring water from a bottle into a glass requires representing their relative spatial positions (spatial information) and knowing that such objects are found together, or one by one (temporal dynamics), in typical contexts, such as a kitchen (semantic ...

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 ...

Evidence of allocentric spatial learning in male rats with large lesions of the hippocampus. [PDF]

PLoS ONE
The hippocampus (HPC) is the neural substrate of viewpoint-invariant cognitive maps, also known as allocentric spatial representations. Lesions of the HPC disrupt performance on allocentric tasks like the Morris Water Task (MWT), in which rodents must ...

Standing in unperturbed balance improves spatial memory and facilitates allocentric representation [PDF]

Frontiers in Behavioral Neuroscience
Wheelchair users face numerous challenges, which might include experiencing the world from a sitting modality, thus resulting in poorer spatial representation.

Landmark-based spatial navigation across the human lifespan

eLife, 2023
Human spatial cognition has been mainly characterized in terms of egocentric (body-centered) and allocentric (world-centered) wayfinding behavior. It was hypothesized that allocentric spatial coding, as a special high-level cognitive ability, develops ...

Patients with Parkinson’s Disease Show Alteration in their Visuospatial Abilities and in their Egocentric and Allocentric Spatial Orientation Measured by Card Placing Tests

Journal of Parkinson’s Disease, 2020
Background: Visuospatial skills are impaired in Parkinson’s disease (PD). Other related skills exist, such as spatial orientation have been poorly studied.
