Perception of Depth in Rotating Objects: 7. Influence of Attributes of Depth on Stereokinetic Percepts

Abstract

The effects of a number of factors that influence apparent depth on the fluctuation rates of three visual information processing mechanisms were examined, viz., the near-far, one object-multiple object, and anchor point mechanisms. The factors tested were overlay, brightness, shadows, texture, asymmetry, speed, and differential brightness, size and speed within the stimulus, and viewing time. Any increase in apparent depth tended to stabilize all three mechanisms. However, each was shown to occur independent of the others, and each could be selectively inhibited by at least one condition. The relationship of apparent slant and velocity was discussed.
