sensation and perception

Question 1

sensation

Answer 1

physical stimulation of the 5 senses processed by sense receptors (feeling)

Question 2

perception

Answer 2

brain interpreting and organising the sensory information (thinking)

Question 3

sensation vs perception

Answer 3

Sensation is the detection of the stimulus.
Perception is interpreting what it means.

Question 4

theories of perception

Answer 4

Perception theories differ.
Gregory sees a difference between sensation and perception.
Gibson does not.

Question 5

visual cues and constancies

Answer 5

Cues – info about movement, distance etc
Constancies – seeing object as the same from different angles and distances

Question 6

binocular depth cues

Answer 6

• retinal disparity
• convergence

Question 7

retinal disparity

Answer 7

difference between the view of the left and right eye gives brain info about depth and distance

Question 8

convergence

Answer 8

eyes point closer together when an object is close. Muscles work harder so know distance and depth.

Question 9

monocular depth cues

Answer 9

• height in plane
• linear perspective
• occlusion
• relative size

Question 10

height in plane

Answer 10

objects higher up appear further away

Question 11

relative size

Answer 11

small objects appear further away

Question 12

occlusion

Answer 12

if one object obscures part of another object, it is seen as closer

Question 13

linear perspective

Answer 13

parallel lines appear closer as they become more distant
