Hearing and seeing is the abstraction of the structured sensory energy that signifies objects out of the ongoing flux. For both, all sensations are understood to belong to objects and are understood with respect to the properties of objects. However, there is always inherent uncertainty about the multiple stimulus properties that define objects due to sensory limitations, memory limitations, or even environmental obstacles. Sensory limitations force us to view the world through a narrow aperture one part at a time, and at the same time limit our ability to resolve different sensory properties. Memory limitations restrict our ability to find correspondences between sensory information at different spatial positions and times. To maximize performance, all sensory systems encode energy at multiple resolutions to make use of several spatial and temporal scales simultaneously.
