Abstract

Although validated procedures exist for group measurement of illusions of extent and area, few exist for the measurement of illusions of direction and orientation. Two new group- measurement techniques, for the Poggendorff and Zoellner illusions, are presented. These are shown to be sensitive enough to detect the usually obtained parametric variations of illusion magnitude with specific changes in stimulus configurations.
