(7) Monocular Cue: Interposition

Interposition is the when an object partially blocks our view of another, causing us to perceive it to be closer to us.

The image displayed above shows two completely different shapes of different color. Because the blue oval is show to be overlapping the rectangle, our minds immediately assume that it is also closer to us. This is due to us registering the fact that we see the full shape of it rather than the rectangle.
