ABSTRACT The published literature on attitudes toward environment and space has neglected ambiguity and ambivalence, an aspect of human psychology which we all recognize, but one which is difficult to measure. Three conditions promote ambiguity and ambivalence: 1) complex environments (stimuli); 2) the discrepancy between the mind's search for symmetry and life's bias in favor of movement and of certain psychological values; and 3) the tendency for feelings and primitive concepts to polarize.
