Paper Abstract
We investigate the hypothesis that the basic representation of space which underlies human navigation does not
resemble an image-like map and is not restricted by the laws of Euclidean geometry. For this we developed a
new experimental technique in which we use the properties of a virtual environment (VE) to directly influence
the development of the representation. We compared the navigation performance of human observers under two
conditions. Either the VE is consistent with the geometrical properties of physical space and could hence be
represented in a map-like fashion, or it contains severe violations of Euclidean metric and planar topology, and
would thus pose difficulties for the correct development of such a representation. Performance is not influenced
by this difference, suggesting that a map-like representation is not the major basis of human navigation. Rather,
the results are consistent with a representation which is similar to a non-planar graph augmented with path
length information, or with a sensorimotor representation which combines sensory properties and motor actions.
The latter may be seen as part of a revised view of perceptual processes due to recent results in psychology and
neurobiology, which indicate that the traditional strict separation of sensory and motor systems is no longer
tenable.
