Unit 3 topic 2- Psychological effects on visual perception

Question 1

Answer 1

Visual perceptual principles that guide organization and interpretation of stimuli. the whole image causes meaningfulness

Question 2

1. Figure ground principle

Answer 2

organising part of stimuli that is attended to away from background

Question 3

2. closure

Answer 3

tendency to complete an incomplete stimuli and perceive it as a whole

Question 4

3. similarity

Answer 4

Question 5

4. proximity

Answer 5

tendency to mentally group objects that are positioned together

Question 6

Depth perception

Answer 6

ability to interpret the world as 3D

Question 7

Binocular depth cues

Answer 7

depth cues that rely on information from both eyes

Question 8

Retinal Disparity

Answer 8

binocular depth cue where cortex uses left and right eye to form complete image

Question 9

Convergence

Answer 9

binocular depth cue where cortex uses information about amount of tension placed on orbital muscles to help indicate distance of object from observer. closer object is more tension

Question 10

monocular depth cues

Answer 10

cue to assist perception of depth that only requires information from one eye (mono)

Question 11

pictorial depth cues

Answer 11

cues indicating images distance

Question 12

1. linear perspective

Answer 12

apparent convergence of parallel lines as they recede into the distance

Question 13

2. relative size

Answer 13

objects cast a larger retinal image when closer to observer than when further away

Question 14

3. interposition

Answer 14

when one object obscures vision of another object. object obscured is further distance away from observer.

Question 15

4. texture gradient

Answer 15

objects are closer if they have greater detail than those further away

Question 16

5. Height in visual field
