The process in which sense organs gather information about the environment and transmits it to the brain is known as sensation (Kowalski & Western, 2005). Once the brain has conducted the initial processing, it performs the process of organizing and interpreting the sensations known as perception (Kowalski & Western, 2005). Sensation and perception differ from person to person. A person whom is color blind has a different sensory world than a person whom is not. A person whom is depressed has a different perceptual world than a person whom is not depressed.
