Perception

Perception is the cognitive process by which the brain organizes and interprets sensory information to make sense of the surrounding environment, distinct from the physiological process of sensation. This topic explores the mechanisms of visual processing, including the use of monocular and binocular depth cues and the phenomenon of visual illusions as evidence of cognitive interpretation. It critically examines the debate between nature and nurture through competing theories—specifically Gibson's direct theory of perception and Gregory's constructivist theory—and analyzes how factors such as culture, motivation, emotion, and expectation form perceptual sets.
