Abstract
This research was concerned with the perception of inter-element distance and angle relations for pairs of dots arranged vertically, horizontally, oblique-left, and oblique-right. For each trial, a pair of dots was presented in different global locations, for five consecutive frames. The subject's task was to detect a change in the relative location of the dots, which could occur during one of the five frames. Each subject participated in three different conditions. One condition emphasized the detection of changes in distance between the elements; the second emphasized the detection of changes in the angle formed by the elements. The third condition did not focus attention on either distance or angle changes. Results indicated that focussing attention on either distance or angle changes affected sensitivity to distance changes for rectilinear, but not for oblique arrangements. These results suggested that the vertical and horizontal components of Inter-element distance are perceptually fundamental, and that the Euclidean distance between two elements and the angle formed by the elements are internally computed from the perceptually fundamental distance components.
