Question 26

occurs as an object appears the same, even though the shape of it’s retinal image changes

Answer 26

shape constancy

Question 27

perceive things as retaining the same color or brightness levels even though the amount of light may vary

Question 28

the ability to perceive three dimensional space and to accurately judge distance

Answer 28

depth perception

Question 29

apparatus used to test depth perception in infants

Answer 29

visual cliff

Question 30

closer objects block the view of things far away

Answer 30

interposition (occasion)

Question 31

if two objects are assumed to be the same size, the object producing a larger image on the retina is perceived as closer

Answer 31

relative size

Question 32

more sit at objects are usually higher in the visual field than those nearby

Answer 32

height in the visual field

Question 33

a graduated change in the texture, or grain, of the visual field. texture appears less detailed as distance increases

Answer 33

texture gradient

Question 34

distant objects often appear hazier and tend to take on a bluish tone. object are seen as three dimensional because of shadows

Answer 34

clarity, color, and shadow

Question 35

muscles surrounding the lens either tighten or relax

Answer 40

accommodation

Question 41

rapid expansion in size of an image so that it fills the retina, is automatically perceived as an approaching stimulus and not an expanding object
