What are sensation and perception? What do we mean by bottom-up processing
and top-down processing?

Expert Solution
Step 1 Introduction:

Sensation and perception are two distinct methods that are quite intimately associated.

Senses are the physiological cornerstone of perception. Perception is the sensory encounter of the environment.

Step 2

The sensation is information regarding the physical environment received by our sensory receptors. The individual senses incorporate vision, sound, taste, odor, and feel.

Perception is the method through which the mind chooses, orders, and describes these sentiments. Perception is the classification, description, and analysis of sensory data in sequence to describe and interpret the represented data or circumstances.
