This experiment tested the ability of people to recall the locations of buildings in a familiar campus setting. Ten graduate students represented the relative locations of buildings by pairwise distance judgments and by direct mapping of locations on a Tektronix cathode ray terminal. Both methods led to accurate judgments. (Author/CTM)

This experiment investigated preferences for the location of facilities in an ideal town. Ten graduate students represented the relative locations of facilities (home, school, factory) by two methods: (1) pairwise ideal distances on a 100-point scale and (2) direct planning of locations on a Tektronix cathode ray screen.

This article reviews two experiments on the mapping and planning of actual (campus buildings) and hypothetical (ideal town facilities) items in a two-dimensional space. Direct mapping (planning) techniques are preferred over the method of pair comparisons, especially for the actual environment. (See TM 504 879-880) (Author/CTM)
