Document Summary
Perception: selection, organization, and interpretation of sensory input. Psychophysics: study of how physical stimuli are translated into psychological experience. Vision: there is not a one-one correspondence between physical and psychological reality, sensation and perception are active processes, sensation and perception are adaptive. Contralaterality: left hemisphere and the right hemisphere cross reference to allow you to see all things in your view. The information in your left visual field is sent to your right hemisphere and vice versa. Visual information arrives in the primary visual cortex with maps that are retinotopic. Maps systematically carry information about how light is carried in the world and taken in by retina. Cochlea take sound waves that move the hair and turn it into data that shows information. There are patterns of tones at different frequencies. The construction of a model of the world. Perceptual system fills in contours that are not present in the image.
