New cards
Interposition/Occlusion
= a near object covers/blocks an object farther away
= a near object covers/blocks an object farther away
2
New cards
Relative Size
= far-off objects look smaller than close objects do

(when close objects are the same physical/actual size)
= far-off objects look smaller than close objects do

(when close objects are the same physical/actual size)
3
New cards
Familiar Size
= we know how large familiar objects are, so we can tell ow far away they are by size of their retinal images

ex. being able to tell how far a person is (gets messed up if it’s like a comically large cardboard cutout\`\`)

New cards
Detail/Aerial Perspective
= the further away an object is, the more blurry it is

\
(due to layers of atmosphere)
= the further away an object is, the more blurry it is

5
New cards
Linear Perspective
= parallel lines appear to converge in the distance
= parallel lines appear to converge in the distance
6
New cards
Texture Gradient
= as a uniformly textured surface recedes, its texture continuously becomes denser/smoother-looking
= as a uniformly textured surface recedes, its texture continuously becomes denser/smoother-looking
7
New cards
Position Relative to the Horizon
= for equal-size objects below the horizon, the one that appears higher in the vision field is perceived as being farther away
= for equal-size objects below the horizon, the one that appears higher in the vision field is perceived as being farther away
8
New cards
Motion Parallax
= when observer moving in a vehicle and looking out a window, nearer objects in scenery appear to be moving past faster than those farther in the distance

New cards
Visual Cliff
= research paradigm to test development of monocular depth perception in young children

\
ex. children show apprehension crossing glass where the appearance of a cliff exists

10
New cards
Binocular Disparity
Binocular Disparity
= because 2 eyes are offset, they produce 2 diff images on retina, so brain uses disparity to calculate depth

* far object = not much disparity
* close object = lots of disparity

ex. if bring finger closer to face and close each eye, finger shifts around more the closer it is to eyes

11
New cards
Convergence
= looking at closer objects causes our eyes to converge

* brain uses this info to calculate depth
* when eyes view near object, muscles move eyes toward each other (strain)
= looking at closer objects causes our eyes to converge

12
New cards
Induced Movement
= assumption based on experience that smaller objects must be moving across larger one

\
ex. usually when we see a ball rolling across a table, we think ball is the one moving, not the table moving underneath a stationary ball

\
a misinterpretation of this illusion → the bigger object is moving, but brain assumes otherwise

ex. at traffic light and the big truck next to you starts moving forward and you hit the brakes harder, thinking you are going backward
13
New cards
Stroboscopic Movement
= rapidly flashing stationary pictures seem to move continuously
= rapidly flashing stationary pictures seem to move continuously
14
New cards
Phi Phenomenon
= set of rapidly flashing lights in slightly different places make it seem like light is moving

* similar to stroboscopic movement but for lights
