Haptic space processing--Allocentric and egocentric reference frames. [PDF]

Canadian Journal of Experimental Psychology / Revue canadienne de psychologie expérimentale, 2007
In this paper a haptic matching, task is used to analyze haptic spatial processing. In various conditions, blindfolded participants were asked to make a test bar parallel to a reference bar. This always resulted in large but systematic deviations. It will be shown that the results can be described with a model in which an egocentric reference frame ...

Virtual Orientation Overrides Physical Orientation to Define a Reference Frame in Spatial Updating [PDF]

Frontiers in Human Neuroscience, 2018
Previous studies showed that people could use either an egocentric or allocentric reference frame in spatial updating with body-based cues (i.e., physical body movements), but the adopted reference frame was anchored by the physical egocentric front when

Egocentric reference frame bias in the palmar haptic perception of surface orientation [PDF]

Psychonomic Bulletin & Review, 2013
The effect of egocentric reference frames on palmar haptic perception of orientation was investigated in vertically separated locations in a sagittal plane. Reference stimuli to be haptically matched were presented either haptically (to the contralateral hand) or visually. As in prior investigations of haptic orientation perception, a strong egocentric

The Two-Wrongs model explains perception-action dissociations for illusions driven by distortions of the egocentric reference frame

Frontiers in Human Neuroscience, 2015
Several studies have demonstrated a dissociation of the effects of illusion on perception and action, with perception generally reported to be susceptible to illusions, while actions are seemingly immune.

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).

Distinct Neural Dynamics of Spatial Transformations: Egocentric Perspective-Taking and Allocentric Rotation [PDF]

Brain Sciences
Background/Objectives: Egocentric and allocentric spatial transformations are central to spatial cognition, yet it is unknown whether they rely on the same neural mechanisms. The goal of this study was to examine whether egocentric transformations engage

Sensing flow gradients is necessary for learning autonomous underwater navigation [PDF]

Nature Communications
Aquatic animals are much better at underwater navigation than robotic vehicles. Robots face major challenges in deep water because of their limited access to global positioning signals and flow maps.

Tracking down abstract linguistic meaning: neural correlates of spatial frame of reference ambiguities in language. [PDF]

PLoS ONE, 2012
This functional magnetic resonance imaging (fMRI) study investigates a crucial parameter in spatial description, namely variants in the frame of reference chosen.

Right parietal lesions, unilateral spatial neglect, and the egocentric frame of reference

NeuroImage, 2003
Recently, the hypothesis has been proposed that the crucial mechanism leading to neglect is the disturbed transformation of sensory input into a supramodal egocentric frame of reference (ER), which causes in turn a deviation of this reference frame toward the side ipsilateral to the brain lesion.

The effect of egocentric and environmental cues on macro-reference frame selection

, 2018
Knowledge of space is inherently relative. Therefore, in order to make use of spatial knowledge, it must be encoded with respect to a particular perspective so that values such distance and angle have meaning. This stored perspective is known as the reference frame, and many judgments about remembered space are calculated based on this perspective ...
