Document Summary
Sensation: stimulus detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: making sense of what our senses tell us active process of organising this stimulus input and giving it meaning. Perception is an active and creative process: the same sensory input may perceived in different ways at different times.
