A TEST OF THE SIZE-DISTANCE INVARIANCE HYPOTHESIS
Abstract
The size-distance invariance hypothesis was tested using three magnitudes of effective interpupillary distance (base). Devices providing an increased, normal, or decreased base were used to view targets at 5, 10, 15, or 20 ft. Both perceived relative and perceived absolute sizedistance invariance hypothesis which states that, for an object of constant angular size, the ratio of perceived absolute siznce is a constant. It was found that while perceived absolute size and perceived absolute distance were related, the ratio of the two varied significantly as a function of both physical distance and base. (Author)
