Answer: Sensation; Perception
Explanation:
Sensation refers to the process of sensing our environment through touch, taste, sight, sound and smell. This information is sent to our brains in raw form where perception comes into play. Perception is the way we interpret these sensations and therefore make sense of everything around us. Sensation has to do with the detection of external or internal stimuli such as pain, while perception deals with identification, and interpretation of sensory information in order to represent and understand the presented information.
