Distance Estimation from Cognitive Maps.
Abstract
Four experiments investigated map clutter as a source of distortion in distance estimates. In Experiments 1 and 2, subjects estimated distances between pairs of points on a memorized map. In Experiment 1, subjects learned relative distances among cities incidentally; in Experiment 2, they learned them intentionally. In both experiments, estimates increased as a linear function of the number of intervening points along the path. In Experiment 3, subjects estimated distances while viewing the map. The clutter effect was reduced but not eliminated. In Experiment 4, the clutter effect was demonstrated using subjects' pre-experimental knowledge of U.S. geography.
