Monocular Cues. : Interposition

Interposition is when an overlap of something causes us to perceive depth in an object. Probably the most well known example of this is an eclipse. The moon eclipses the sun which causes us to perceive depth of the sun and the moon

Monocular Cues : Relative Clarity

Relative Clarity is when we believe that hazy objects appear farther than sharp clear objects which appear to be closer. In this picture the person with the basketball appears to be farther due to their appearance being hazy. The tricks the mind into thinking that the person is farther than they actually are.

Monocular Cues: Relative Height

Relative Height is where distant objects appear to be smaller and higher in compared to items that are closer. In this picture the gravestones that are farther away from the front appear to have a smaller height than that of the gravestones closer to the camera.

Monocular Cues : Relative Size

                
A monocular cue is a part of depth of perception which allows us to perceive the distance of an object. There are different varieties of monocular cues, one monocular cue is called relative size. If two objects are known to be the same size but their absolute size is unknown, relative size cues can provide information about the relative depth of the two objects. So in this picture and in real life when the moon is closer to the horizon people believe that it is larger due to their relative size, but when the moon is in the sky there is nothing to compare it to so it seems to be smaller. This type of relative size illusion is called a lunar illusion.

Continuity

Continuity

Continuity is how we usually perceive smooth and continues patterns that do not change direction or make jagged turns. This is seen here because these intersecting train tracks are viewed as two lines going straight through two other lines and then continuing. Instead of viewing the as two V shaped figures that touch each other then go away from

Similarity

Similarity

This organization of perception describes how we see similar things as grouped together. Therefore when looking at this crowd we group together the different colors to make the American Flag, instead of just seeing a bunch of random colors that are not connected or grouped together.

Closure

Closure

Closure relates to how when people view something they tend to fill in the gaps and make the thing we are seeing into a known object that has meaning. This is why when we see this cloud in the sky we can immediately see that it looks like duck because we fill in where there should be other clouds so that it looks like a completed figure.
