FUZZY LINGUISTIC AND METRIC FORMALIZATIONS OF COGNITIVE DISTANCE
Subjects engaged in learning their spatial environmental have increasingly detailed and complete information available to them at each stage in the process. This paper describes a three-stage spatial learning process based on three fuzzy formalizations of cognitive distance involving three types of information: (1) relative distance expressed linguistically in terms of closeness and/or remoteness, (2) absolute distance expressed linguistically in terms of short, long and their shades of meaning and (3) absolute distance expressed numerically. Finally, a precise method of matching subjects' linguistic and numerical judgments on absolute distances is set out.
