As we view our world, each eye movement causes a dramatic shift in the retinal position of every object in a scene, every blink interrupts visual sensation, and moving objects occlude other objects. Somehow our per-ceptual system makes sense of this varying information and we experience a stable visual world. How do we sense stability in the face of such dis-ruptions? What sorts of representations underlie this experience? Scenes can be described in terms of the quantity and quality of the information available for representation. To adequately describe the nature of the representations underlying our experience, we must ascertain both how many items in a scene are retained and how much detail about each item is retained. Although these dimensions are not necessarily indepen-dent, after all, both are forms of visual information. The distinction will prove useful in characterizing the possible inferences we can draw from studies of visual representations. Almost all models of visual stability con-cur that some information from a scene is preserved from one view to the
