1 3A sensory adaptation 1 09/03/18 What is the difference between sensation and perception? sensation : Perception: The process of detecting a stimulus, such as light waves (vision) , sound waves (hearing) , chemical molecules (smell and taste ), heat or pressure (touch). The process of integrating, organizing and interpreting sensations. 3A sensory adaptation 2 09/03/18 You might want to think of sensation and perception as two ends of a continuum.
