Perceptual information processing is the most basic one in our communication process. Given an object or a pattern, we see it and analyze the basic perceptual attributes i.e., lightness, color, orientation, size, form, depth, and motion direction as visual attributes, and loudness, pitch, and harmonics as auditory attributes. Then we integrate and synthesize them and attain a total meaning through comparing with memory representation. We recognize that it is a car or a melody. We still do not know completely about where and how the information of these attributes are analyzed and synthesized in our sensory system and brain. We are investigating the perceptual information processing at the initial level to the higher-order level.
