Document Summary
Perception is : an active process (closely related to sensation) by which the brain selects, organises, and interprets sensations. Sensory impressions are a ected by context, by experience, by emotional states : our perceptual experience is not an objective reproduction of what is out there, instead it is a construction of reality that is manufactured by the brain. Three principles emerge from the study of sensation and perception: there is no one-to-one correspondence between physical and psychological reality, sensation and perception are active (not passive) processes, sensation and perception are adaptive (facilitate survival and reproduction). Perception involves the organisation and interpretation of sensory experience. Gestalt psychologists described several principles of form perception. More recently, a theory called recognition-by-components has argued that people perceive and categorise objects by. The brain"s e orts to organise percepts can sometimes produce perceptual illusions. Depth perception is the organisation of perception in three dimensions; it is based on binocular and monocular visual cues.
