WEBER'S LAW APPLIED TO DISTANCE ESTIMATION,
Abstract
The stimulus situation in dynamic range estimation is examined. The solid angle, taking into account the area of the target as well as the distance, is used as the visual concept, and the prediction made that range estimation would follow Weber's Law. The results support the hypothesis that absolute errors in range estimation are an inverse function of the acceleration of the increase in size of the solid angle representing the target. The study suggests that one problem in research dealing with dynamic range estimation is that the results to be expected are highly dependent on the experimental conditions. (Author)
