Law of Proximity: States that objects that are near or proximate, to each other tend to be grouped together. This law is a part of the Gestalt Laws of Perceptual organization and also gestalt psychology founded by Max Wertheimer. Movies or motion pictures are two examples of the law of proximity, because movies are just a rapid succession of still images that create a seamless visual experience. According to the laws of proximity, things that are near each other tend to be grouped together.

Law of Figure-Ground Perception: Used to describe 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). This law is often illustrated with the "faces or vases" illusion, also known as Rubin Vase. This depends on what you see as the black or white figure, you can either see two faces (black) in profile or a vase in the center (white). The flag of Canada can also be seen as Figure-Ground Perception, because the flags background edges of the maple leaf can can also be seen as two faces arguing. 

Binocular Cue: Us as humans are able to see things that are both far and near, and we can actually identify where these things are in space. This is a sort of depth perception that requires both of our eyes, also known as binocular cues. The first example of this theory; if you hold one finger about six inches away from your eyes and look at it, then move it a foot farther. You will actually be able to feel the change in eye muscles at different distances. Another example of Binocular cues is the "visual cliff" experiment that was used on infants.
