Question 12

our eyes can converge to …

Answer 12

about 10cm

Question 13

Binocular visual sources

Answer 13

each eye has a slightly different angle

triangulating

Question 14

monocular visual sources

Answer 14

interposition
linear perspective
reduced clarity
height
relative size
shading
texture gradients
movement gradient

Question 15

interposition

Answer 15

closer objects block the view of farther away objects

Question 16

linear perspective

Answer 16

the reduced clarity closer together two converging lines are, the greater the distance perceived

Question 17

reduced clarity

Answer 17

greater distance usually reduces clarity

Question 18

height in visual field

Answer 18

farther objects usually higher up in visual field

Question 19

shading

Answer 19

light and shadow contribute to dimension perception

Question 20

texture gradients

Answer 20

texture appears smaller and may be less detailed as distance increases

Question 21

movement gradient

Answer 21

the distance in relative motion provide cues to the difference distance

Question 22

global to local recognition

Answer 22

recognize the whole then the parts

Question 23

local to global recognition

Answer 23

recognize parts then construct the whole

Question 24

what type of processing contributes to pattern recognition

Answer 24

both top down and bottom up

Question 25

reification

Answer 25

the constructive or generative aspect of perception, perceived info is more explicit than the sensory stimulus itself

Question 26

are some experts able to “see” better?

Answer 26

no, low level processes don’t work like that
