Updating egocentric representations in human navigation
Further experiments examine the relative precision of transient and enduring representations and show that switching between them does not require disorientation, but can also be produced by self-rotations as small as 135°.Citation Context ..a navigation task can be solved only by representing the geometry of the surface layout or only by representing landmarks, for example, no sex differences appear at any age (Hermer & Spelke, 1996; =-=Wang & Spelke, 2000-=-).
It is now becoming possible to construct a mechanistic neural-level model of at least some aspects of spatial memory and imagery, with the hippocampus and medial temporal lobe providing allocentric environmental representations, the parietal lobe egocentric representations, and the retrosplenial cortex and parieto-occipital sulcus allowing both types of representation to interact.If that is so, it seems odd to find human communities that rely heavily on allocentric representations, at least linguistically.We will begin by thinking about global distinctions among the cultur... The authors model the neural mechanisms underlying spatial cognition, integrating neuronal systems and behavioral data, and address the relationships between long-term memory, short-term memory, and imagery, and between egocentric and allocentric and visual and ideothetic representations.Examples of qualia include the pain of a headache, the taste of wine, and the perceived redness of an evening sky.Spatial memory appears to be supported by multiple parallel representations, including egocentric and allocentric representations, and those updated to accommodate selfmotion.
The effects of these representations can be dissociated behaviorally, developmentally, and in terms of their neural bases.
