Abstract:

A study was made to apply a hypothesis involving the perceptual interrelation of frontal and binocular depth extents to the problem of perceptually duplicating a binocular depth extent at different distances. Two experiments were conducted to apply a previously developed hypothesis to the problem of the perceptual duplication of a depth interval at different distances from the subject using binocular disparity cues. Both frontal size judgments and depth duplication judgments were obtained in situations in which there were a variety of cues of the perceived distance of one object in each pair of objects used in generating the depth intervals. In general, the results support the hypothesis. As predicted, the amount of binocular disparity required at one distance to perceptually duplicate a given binocular disparity at another distance was related to the amount of frontal size constancy between the two distances. It is recommended that the perceptual processes involved in the use of other cue systems be investigated with the objective of specifying the depth perceptions which will occur in visually complex situations.
