Document Summary
Perception: when the brain organizes sensations (information derived from sense organs) into meaningful patterns. Sensory adaptation: a process in which sensors respond less to unchanging stimuli (ex. Getting used to a smell in a room) Sensory analysis: the process in which senses process and divide the information into basic stimulus patterns. Sensory coding: the process in which information is converted into neural messages understood by the brain. Selective attention: voluntarily focusing on a specific sensory input. Rods and cones: image sensors that detect different colors and details. Dark adaptation: the dramatic increase in retinal sensitivity to light that occurs after a person enters the dark. Frequency theory: states that as pitch rises, nerve impulses of a corresponding frequency are fed into the auditory nerve. Conductive hearing loss: occurs when the transfer of vibrations from the outer ear to the inner ear weakens. Sensorineural hearing loss: results from damage to the inner ear hair cells or auditory nerve.
