Sensation & Perception
§How do we construct our representations of the external world?
§
§To represent the world, we must detect physical energy (stimulus) from the environment and convert it into neural signals, a process called sensation.
§
§When we select, organize, and interpret our sensations, the process is called perception.
OBJECTIVE 12-1| Contrast sensation and perception, and explain the difference between bottom-up and top-down processing.
