In philosophy, and psychology/cognitive sciences, perception is the process of attaining awareness or understanding of sensory information. The word "perception" comes from the Latin words perceptio, percipio, and means "receiving, collecting, action of taking possession, apprehension with the mind or senses."

Perception is one of the oldest fields in psychology. The oldest quantitative law in psychology is the Weber-Fechner law, which quantifies the relationship between the intensity of physical stimuli and their perceptual effects. The study of perception gave rise to the Gestalt school of psychology, with its emphasis on holistic approach.

What one perceives is a result of interplays between past experiences, including one’s culture, and the interpretation of the perceived. If the percept does not have support in any of these perceptual bases it is unlikely to rise above perceptual threshold.

• I see the same sadness in the eyes of conformists as I do in the eyes of those convulsing radically in opposition. I talk to people that aren't like me, individually, thoughtfully. And I listen. If I walk away from a conversation thinking differently than before I entered into it, I have succeeded in doing something that doesn't compute. If I haven't interacted and challenged what I know, resulting in a change of perception, I am still running my own set of stupid old programs.
