Word of the Day monocular cues depth cues available to either eye alone. Ex. linear perspective, light and shadow effect
Examples: Relative Size: If two objects are roughly the same size, the object that looks the largest will be judged as being the closest to the observer.
Texture Gradient
Texture Gradient: When you are looking at an object that extends into the distance, such as a grassy field, the texture becomes less and less apparent the farther it goes into the distance. 
Motion Parallax: As you are moving, objects that are closer seem to zoom by faster than do objects in the distance. When you are riding in a car for example, the nearby telephone poles rush by much faster than the trees in the distance
Aerial Perspective: Objects that are far away appear blurred or slightly hazy due to the atmosphere
Aerial Perspective
Ponzo Illusion (Linear Perspective)
Linear Perspective: Parallel lines appear to meet as they travel into the distance. For example, the outer edges of a road seem to grow closer and closer until they appear to meet. The closer together the two lines are, the greater the distance will seem. 
Binocular cues-requires both eyes. Ex. depth perspective Eleanor Gibson & the Visual Cliff experiment Gibson placed infants on a plexi-glass topped table. On one side the top was covered with a red and white checkered pattern this was done to give the illusion of a deep end or a visual cliff. When infants were placed on it they almost ALWAYS refused to go beyond the edge of the visual cliff, even when their mothers were coaxing them to crawl across. Conclusion depth perception in humans is an innate ability you are born with it.
