“…Although retinal adjacency and perceived adjacency (in the frontal plane) are normally confounded, White teased them apart using a moving-eye technique analogous to that introduced by Rock and Ebenholtz (1962) to demonstrate that stroboscopic motion requires a change of perceived location, not a change of retinal location. The crucial role of perceived depth in stroboscopic motion has been shown by Attneave and Block (1973) and Corbin (1942), and its role in induced motion has been shown by Gogel and Koslow (1972).…”

Experiments have recently been reported in which a decisive change in perceived lightness was produced by a change in perceived spatial position, with no important change in the retinal image. A number of previous studies had found little or no such effect. Experiments of the kind that produced these effects and of the kind that do not produce these effects are presented here. The main differences between these two kinds of experiments are discussed. One difference is whether the display allows the target to be part of one ratio in one spatial position but another in the other spatial position. Another difference concerns the range of luminances within the display. Also discussed are the implications of these findings for cognitive vs. S-R theories, the order of processing depth and lightness, laboratory data vs. experience, the role of lateral inhibition in lightness perception, and theories of lightness perception in general.

“…Gogel and Koslow (1972) used two frames to demonstrate an adjacency principle of induced motion. In one of their dual-frame displays, the near and far frames moved in opposite directions below the subject-relative threshold for motion, and a stationary dot appeared in the near plane, the far plane, or at a distance halfway between the two.…”

“…Our displays use two frames and resemble the Gogel and Koslow (1972) demonstration of an adjacency principle for induced motion. However, there are good reasons for believing that our experiments cannot be explained by the adjacency principle and induced motion.…”

Four experiments are reported that investigated the role of the perceived coplanarity of a moving target with respect to a frame of reference in the third dimension on the perceived path of that target. When a target dot and small moving frame appeared coplanar, the dot's perceived trajectory was governed entirely by its changing position relative to the moving frame. However, when the target and a large stationary frame appeared in a different plane than the small moving frame, the motion of the dot was seen independently of the moving frame. The results support a belongingness principle of motion perception: The displacement of an object relative to a frame of reference to which it belongs governs its perceived path of motion.

“…In two studies of induced motion, the perceived (stereoscopic) depth between the induction and test object has been found to be a significant variable in determining the magnitude of induced motion (Gogel & Koslow, 1971).and its direction (Gogel & Koslow, 1972). These results are interpreted as supporting the adjacency principle which states that the effectiveness of cues between objects in determining perceived object characteristics, e.g., perceived size or motion, is inversely related to the perceived separation (either frontoparallel or in depth) between the objects (Gogel, 1970).…”

The effect of depth displacement of test bars from the induction wedge of the Ponzo illusion was investigated in two experiments. Either two wedges of opposite orientation were presented simultaneously, one at a near and the other at a far distance, or only one wedge was presented at either the near or the far distance. The test bars were stereoscopically either in the plane of the wedge or displaced from the wedge in distance. When the two wedges were presented simultaneously, the direction of the Ponzo illusion was determined by the wedge at the same perceived distance as the test bars. When only one wedge was present, stereoscopic displacement of the bars in front of, but not behind, the wedge decreased the magnitude of the illusion. The results are interpreted in terms of the adjacency principle.
