Decreased utilization of allocentric coordinates during reaching movement in individuals with autism spectrum disorder

PLoS ONE, 2020
Despite numerous reports of abnormalities in limb motor controls in spatial orientation in individuals with autism spectrum disorder (ASD), the underlying mechanisms have not been elucidated. We studied the influence of allocentric coordinates on ongoing

Spatial Demonstratives and Perspective Taking in English and Japanese. [PDF]

Cogn Sci
Abstract There is much debate regarding the extent to which languages express the same spatial parameters or whether spatial communication is essentially diverse. In this paper, we explore “perspective taking” in spatial demonstrative systems as a means of exploring between and within language variation.

Emergent spatial goals in an integrative model of the insect central complex.

PLoS Computational Biology, 2023
The insect central complex appears to encode and process spatial information through vector manipulation. Here, we draw on recent insights into circuit structure to fuse previous models of sensory-guided navigation, path integration and vector memory ...

Scene Configuration and Object Reliability Affect the Use of Allocentric Information for Memory-Guided Reaching [PDF]

, 2017
Previous research has shown that egocentric and allocentric information is used for coding target locations for memory-guided reaching movements. Especially, task-relevance determines the use of objects as allocentric cues.

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).

Different strategies for spatial updating in yaw and pitch path integration

Frontiers in Behavioral Neuroscience, 2013
Research in spatial navigation revealed the existence of discrete strategies defined by the use of distinct reference frames during virtual path integration.

Spatial task context makes short-latency reaches prone to induced Roelofs illusion

Frontiers in Human Neuroscience, 2014
The perceptual localization of an object is often more prone to illusions than an immediate visuomotor action towards that object. The induced Roelofs effect (IRE) probes the illusory influence of task-irrelevant visual contextual stimuli on the ...

Egocentric Reference Frame Bias In The Palmar Haptic Perception Of Surface Orientation [PDF]

, 2014
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

Learning a Path from Real Navigation: The Advantage of Initial View, Cardinal North and Visuo-Spatial Ability

Brain Sciences, 2020
Background: Spatial cognition research strives to maximize conditions favoring environment representation. This study examined how initial (egocentric) navigation headings interact with allocentric references in terms of world-based information (such as ...
