Perception
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Perception is the organization and interpretation of sensory signals into a meaningful experience.
Show
The same pattern of light on the retina becomes a face, and it becomes a face in the brain rather than in the eye.
Watch for
Perception can occur without accurate sensation and can fail with accurate sensation. They are separable.
