Abstract

It was found that the relationships between apparent size and physical distance are expressed by General Functions I, II, III, IV, and those between apparent distance and physical distance by a power function. General functions which describe the relationships between apparent size and apparent distance and visual angle, etc. of an object were derived from much available data. These functions were verified with a set of experiments using the method of ratio estimation. The ‘size-distance invariance hypothesis’, so called by Kilpatrick and Ittelson, is a special case of these general functions. It was found that the validity of ‘Rump's function’ is dependent on the experimental conditions. The equation of transformation was found between the data obtained by the method of ratio (magnitude) estimation and the method of transposition.
