Depth Perception

AP PSYCH

depth perception

is the ability that allows us to judge distances, understand how far away objects are, and move through the environment safely

-we see in 3D, but retina is in 2D

monocular cues

depth and distance cues that can be interpreted with 1 eyes

interposition

that partial blocking of 1 object by another object, leaving the people with the perspective that the blocking object is closer

linear perspective

parallel lines appear to converge at a vanishing point in the horizon

relative size

if 2 objects are similar in size, the object that looks the largest will be judged as being the closest to the observer

texture gradient

-objects in the foreground have clear, detailed texture (closer)

-objects in the distance appear smoother or less detailed

monocular cues

-interposition

-linear perspective

-relative size

-texture gradient

binocular cues

depth and distance cues that require both eyes

convergence

when two eyes inward (to the nose) to see near objects, and outward (away from the nose) to see far away objects

-the more the eyes turn inward, the closer we perceive the objects to be

retinal disparity

each eye sees a slightly different image as they are about 6cm apart (on average), your brain puts the 2 images it receives together into a single 3D iamge
