ABSTRACT
If cognitive mapping is to become a useful tool in environmental design, we must have measures which are reliable and valid. The four measures studied here are highly reliable. The data also suggest that the subjective distances between points depend primarily on (1) the actual distances, and to a lesser extent on (2) the paths traveled by the subjects from one point to the other, and (3) the frequency of environmental features along the path. The four methods thus have equal construct validity to the extent that the cognitive-map construct allows these interactions.
