Answer:
Interposition is a depth perception that occurs when one object overlaps another object that is related to the depth perception of an object. It is a monocular depth perception in which an object covers another object. It shows that the object that is overlapped and the object that overlapped another object appears as one that is further away. The monocular cue is another depth perception that has been perceived by one eye. It is the opposite of the binocular depth perception that requires both eyes to perceive an object.
