The Interaction of Sensory and Perceptual Variables: Spatial, Temporal and Orientation Response to Figure and Ground.

Numerous experimental observations support the principal investigators conjecture that human visual segmentation of figure and ground is partly determined by properties of the visual scene. Support derives from observations that figure and ground occupy different perceptual depth planes perceived differences of depth are necessary for figure-ground segmentation patches of an image are assigned to depth planes partly on the basis of their relative spatial frequency content, temporal frequency content distinguished from perceived velocity, and retinal disparity. Details of these and other experiments are included with discussion and references. KeywordsSpace perception.
