Effects of the cognitive organization of route knowledge on judgments of macrospatial distance

The effects of route segmentation were examined in a series of three experiments, Subjects in Experiment 1 divided an actual route into segments. Subjects in Experiment 2 performed corresponding proximity-judgment and distance-estimation tasks involving locations selected on the basis of the route segments identified in Experiment 1. Subjects in Experiment 3 performed a simple unidirectional distance-estimation task. Results from these experiments indicated that subjects can readily divide a route into segments and that these segments significantly bias judgments of macrospatial distance. These findings suggest a similarity between route segmentation in macrospatial cognition and categorization in other cognitive-task domains.
