Cognitive load in switching between egocentric and allocentric spatial frames of reference: a pupillometry study [PDF]
Scientific ReportsEvery 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 and egocentric reference frames in the processing of three-dimensional haptic space [PDF]
Experimental Brain Research, 2008 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.

Visual Target Localization, the Effect of Allocentric Audiovisual Reference Frame
i-Perception, 2011 Visual allocentric references frames (contextual cues) affect visual space perception (Diedrichsen et al., 2004; Walter et al., 2006). On the other hand, experiments have shown a change of visual perception induced by binaural stimuli (Chandler, 1961 ...

Egocentric Spatial Memory Deficit in Amnestic Mild Cognitive Impairment Revealed Through Virtual Reality: Cross-Sectional Study [PDF]
JMIR AgingBackgroundSpatial 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 PsychologyIn 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).

Challenges for identifying the neural mechanisms that support spatial navigation: the impact of spatial scale [PDF]
Frontiers in Human Neuroscience, 2014 Spatial navigation is a fascinating behavior that is essential for our everyday lives. It involves nearly all sensory systems, it requires numerous parallel computations, and it engages multiple memory systems.

Nature CommunicationsUnderstanding 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 ONEThe 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 ...

Identifying a distractor produces object-based inhibition in an allocentric reference frame for saccade planning [PDF]
Scientific ReportsWe investigated whether distractor inhibition occurs relative to the target or fixation in a perceptual decision-making task using a purely saccadic response. Previous research has shown that during the process of discriminating a target from distractor,

Allocentric and egocentric spatial representations coexist in rodent medial entorhinal cortex [PDF]
Nature CommunicationsSuccessful navigation relies on reciprocal transformations between spatial representations in world-centered (allocentric) and self-centered (egocentric) frames of reference.
