Stereopsis and perceptual organization

Show Summary Details


This chapter discusses how stimuli at different depths interact. The apparent spatial disposition of an object can be influenced by its position and orientation relative to other objects. For instance, we can perceive a missing part of a 3-D surface by depth interpolation from neighboring surfaces. Also, the perceived relative motion of two objects is influenced by how they are arranged in depth. The perceived whiteness of a surface can be influenced by a change in the orientation of the surface. Stimuli that interact when seen at the same depth may cease to interact when separated in depth. Depth-specific effects allow us to attend to objects at one depth without being distracted by things at other depths. For example, we can visually pursue a moving object at one distance while ignoring motion signals at other distances.

Keywords: depth interpolation; relative motion; depth-specific effects; attention in 3-D space
