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.

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 ...

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 ...

Egocentric and Allocentric Spatial Memory in Korsakoff’s Amnesia [PDF]

Frontiers in Human Neuroscience, 2020
The goal of the present study was to investigate spatial memory in a group of patients with amnesia due to Korsakoff’s syndrome (KS). We used a virtual spatial memory task that allowed us to separate the use of egocentric and allocentric spatial ...

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 ...

Allocentric Emotional Affordances in HRI: The Multimodal Binding [PDF]

Multimodal Technologies and Interaction, 2018
The concept of affordance perception is one of the distinctive traits of human cognition; and its application to robots can dramatically improve the quality of human-robot interaction (HRI).

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 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.
