What Are the Basic Perceptual Processes?
8. Perception occurs in the brain: The primary auditory cortex handles hearing. Touch is handled by the primary somatosensory cortex. Vision results from a complex series of events in a variety of areas of the brain but primarily in the occipital lobe. 9. Object perception requires construction: By using the Gestalt principles of stimulus organization, we are able to perceive our world. We use cues about similarity, proximity, form, figure and background properties, and shading. Perception involves the dual processes: bottom-up (sensory information) and top-down (brain organization). 10. Depth perception is important for locating objects: The pattern of stimulation of an object on each of the two retinas (binocular) informs the brain about depth. Pictorial (monocular) cues use information from the appearance of objects relative to their surroundings to inform about depth, as well as relative motion. 11. Size perception depends on distance perception: Illusions of size can be created wh
