How does encountering space influence spatial cognition? Mental representation of point of view sequences when perceiving spatial layouts.

In this paper we examine the structure of route knowledge. Route knowledge is considered as a mental representation of so-called <<point of view sequences>>. These se quences are generated when people perceive different distances to, and/or perspectives on, multiple objects by moving through a specific spatial layout. Thus, point of view sequences supply varying egocentric informations that merely temporal series do not. A second specification of point of view sequences is given by examining the direction of perceiving a spatial layout and the direction of moving through it. These sequences are represented when both directions are the same. They are not represented when both directions work against each other. Three experiments within the priming paradigm have been carried out to demonstate these theoretical hypotheses: (1) Along with point of view sequences, there is stronger spread of activation across the spatial knowledge structure than in the opposite direction (= effect of route direction). (2) The effect of route direction cannot be reduced to the mere superiority of forward associations compared to backward associations, as this can occur through the presentation of merely temporal series. (3) This effect remains significant when spatial layouts are encountered by looking and moving in the same direction. It is not found, when these directions lead to opposite informations.
