Document Summary
Vision involves the perception of objects in three dimensions, at variety of distance, with multitude of colours and textures complex stimuli may occur at a single point in time or over an extended period. May involve an unchanging scene or rapidly changing one. Other sense analyze much simpler stimuli (odour/taste) or depend on time and stimulus change for the development of a complex perception. Example: to perceive a solid object in three dimensions by means of touch, must manipulate it-turn it over in our hands or move our hands over its surface. Stimulus must change over time for a full-fledged perception of form to emerge. Same for audition: we hear nothing meaningful in an instant sound consists of rhythmical pressure changes in the air. As object vibrates, causes air around it to move. When object in phase of vibration in which it moves toward you, it compresses molecules of air.
