Q

horopter

A

imaginary curve where the point you are focusing on and all of the elements at the same distance are

17
Q

crossed-disparity

A

object behind another

18
Q

uncrossed disparity

A

objects on different locations and distances

19
Q

stereopsis

A

perception of depth by binocular disparity
-bad visual conditions

20
Q

binocular rivalry

A

2 images are too different creating an unstable situation

21
Q

motion parallax

A

lateral movement of things in the retina
-closer things faster in the opposite direction
-dar items slower in same direction

22
Q

accretion and deletion

A

as you move you see different parts of the partially hidden object

23
Q

Ponzo illusion

A

a rail with two lines, the line at the top appears longer

24
Q

Muller-Lyer Illusion

A

<-> // >-< longer line the one at the right

25
Q

Moon illusion

A

moon in horizon larger (there is terrain) than high in the sky (empty background)
