'Moving into Module 13, so far we have talked a lot about sensation, now we shift to perception. Our senses provide us with raw data about the external world but it must then be interpreted. Perception involves deciphering meaningful patterns in the jumble of sensory information and is the brain's process of organizing and making sense of sensory information. Perception begins with a real world object which activates our sensory system. We never experience the stimulus directly but our perception is usually very accurate. '
