Abstract: | Spatial judgments are affected by both fine-grained and categorical knowledge. We investigated whether, and how, the two forms
of knowledge are learned in real-world, navigable space, as well as the time course of learning each type of knowledge. Participants
were Northwestern University undergraduates who estimated the locations of buildings and other landmarks on campus. The Northwestern
campus is roughly divided into three regions whose borders are not easy to discern, either from a map or by navigation. Nevertheless,
students often refer to these regions linguistically and use them when making housing decisions, choosing classes, and so
forth. We found that knowledge of both the fine-grained configuration of locations and the regional distinctions increased
with time. However, regional influences on judgments occurred later in students’ time on campus. Consequently, computed distances
across the nonexistent border between north and south campus locations became more biased with time. The results have implications
for understanding how spatial representations develop in navigable environments. |
