Abstract
Ss judged two Mueller-Lyer configurations composed of solid and broken contours. The results suggest that there are strong positive and weak negative illusions produced by location and contour mechanisms, respectively. The method of adjustment is not appropriate for broken contours because it introduces motion errors. Within-sets methods are once again shown to be superior to more traditional between-sets methods.
