On the Positioning of Objects in Space

Abstract

The personal spatial structure of an observer is introduced as a central element in the positioning of objects in space. The link between a reference frame used by an observer and his personal spatial structure is discussed. Research on inversion or reversal of incoming light in psychology indicates that the personal spatial structure of an individual, as well as a reference frame that he uses, depends on the internal coordination of sensory stimuli and that the position of objects in space depends in part on psychological factors that affect one's personal spatial structure. Other research in psychology demonstrating the flexibility for an observer in determining the direction of up-down relative to a particular figure, and indeed relative to the entire surround, is also noted and supports the thesis that the observer plays a role in the positioning of objects in space.
