The experiments are centered on a formal model of topological spatial relations, called the 9-intersection. For unbranched lines and simply connected regions, this model identifies 19 different spatial relations. Subjects were presented with two or three geometrically-distinct drawings of each spatial relation (40 drawings in all), with the line and region said to be a road and a park, respectively. In the first experiment, the task was to group the drawings so that the same phrase or sentence to describe every situation in each group. A few subjects differentiated all 19 relations, but most identified 9 to 13 groups. Although there was a great deal of variation across subjects in the groups that were identified, the results confirm that the relations grouped by the 9-interseotion model are the ones most often grouped-by the subjects. No consistent language-related differences were identified among 12 English speaking subjects, 12 Chinese-speaking subjects, and 4 other subjects tested in their own native languages. A second experiment presented the subjects with a short sentence describing a spatial relation between a road and a park, and the same 40 diagrams. Each subject was asked to rate the strength of their agreement or disagreement that the sentence described each relation. For each of the two different predicates tested-"the road crosses the park" and "the road goes into the park"-there was a great deal of consensus across the subjects. The results of these experiments suggest that the 9-intersection model forms a sound basis for characterizing line-region relations, and that many spatial relations can be well-represented by particular subsets of the primitives differentiated by the 9-intersection.
