Figure-Ground Perception Figure-ground perception is the tendency of the visual system to simplify a scene into the main object that we are looking at (figure) and everything else that forms the background (ground).
Gestalt Theory The Gestalt Theory states that the whole of anything is greater than its parts, and includes ways we can group visual information into a whole (proximity, continuity, closure, figure-ground, similarity, common region, focal point).
Visual Cliff A visual cliff is an apparent, but not actual drop from one surface to another, that was originally created to test babies' depth perception.
Interposition Interposition is when a monocular depth cue occurs when two objects are in the same line of vision and the closer object, which is fully in view, partly conceals the farther object.
Relative Size Relative size is a perceptual clue which allows you to determine how close objects are to an object of known size.
Linear Perspective Linear perspective is the fact that we perceive depth when we see two parallel lines that seem to converge in an image.
Closure Closure is the illusion of seeing an incomplete stimulus as though it were whole.
Shape Constancy Shape constancy is a type of perceptual constancy in which an object is perceived as having the same shape when viewed at different angles.
Color Constancy Color constancy is a type of perceptual constancy that allows the brain to recognize a familiar object as being a consistent color regardless of the amount or wavelengths of light reflecting from it at a given moment.
Size Constancy Size constancy is a type of perceptual constancy where we perceive an object as being the same size despite the fact that the size of its retinal image changes depending on its distance from the observer.
