Allocentric and egocentric updating of spatial memories dating centers in annapolis
Precision of spatial updating varies across species and individuals, and errors can accumulate over time. Spatial updating is one of the fundamental forms of navigation that occurs automatically and continuously whenever an animal moves (Schmidt, et al., 1992), and it contributes to object and scene recognition by predicting the appearance of objects or scenes from new vantage points so that the animal can recognize them easily as it moves (Simons & Wang, 1998). Then they make some movements, such as turning or traveling along a path. At the end of the movement, they report the location of these targets, which are now invisible and in new relationships to themselves. Between reality and imagination: When is spatial updating automatic? Usually multiple sources of perceptual information are combined to provide more accurate estimation of self motion. When the cues are in conflict, some cues have stronger influence than others. Spatial updating also has profound impact on spatial reasoning and spatial imagery.
A special case of this test is known as the novel shortcut task.
The basic form of spatial updating is path integration (sometimes called dead reckoning). Human Spatial Representation: Insights from Animals.
