“What” Effects on “Where”: Functional Influences on Spatial Relations

Abstract

Spatial relations indicate the location of an object by specifying its direction with respect to a reference object whose location is known. It has been largely assumed that specific features of these objects are generally ignored in descriptions of spatial location. Within such a view, spatial relations can be described in terms of geometric or topological features that are not dependent on object details such as function. We demonstrate in two experiments that a geometric feature (center of mass) is not sufficient. Using two different tasks, we show that the function of the reference object and its relationship with the other object significantly influence the way in which vertical spatial relations (“above” and “below”) are applied to spatial configurations.
