Perceptual constancy

Question 1

perceptual constancy

Answer 1

the ability to process shifting information to the brain about an object and know the object hasn’t cchanged in sie, shape or orientation (percieve a visual stimulus as remaining constant)

Question 2

what are the three types of perceptual constnacy

Answer 2

size constancy, shape constancy and orientation constancy

Question 3

size constancy

Answer 3

when an individual recognises that a stimulus actual size remains the same despite changes in the information being sent to the brain about the size of the stimulus

Question 4

shape constancy

Answer 4

when an individual recognises that a stimulus’ actual shape remains the same despite changes in the shape of the retinal images being sent to the brain

Question 5

orientation constancy

Answer 5

when an individual recognises that a stimulus’ actual orientation remains the same despite changes in the orientation of the retinal images being sent to the brain (also understanding points of a compass, left right up down)

Question 6

gestalt principles

Answer 6

a set of 4 principles that explain how we interpret visual information by grouping sepeerate visual stimuli together to create a meaningful whole

Question 7

what are the four gestalt princip,es

Answer 7

figure-ground, closure, similarity and proximity

Question 8

figure ground

Answer 8

the tendency to percieve part of a visual stimulus as more relevent (the figure) and standing out against it sless relevent surroundings (the ground)

Question 9

what is the line of seperation between the ground and the figure and whats it purpose

Answer 9

the contour and it helps to differentiate the figure from the ground

Question 10

closure

Answer 10

the ability to close up, fill in or ignore gaps in visual stimuli and percieve objects as a meaningful whole, reducing the mental effort required to percieve incomplete stimuli

Question 11

siimilarity

Answer 11

the tendency to group together as a whole, any stimuli that are alike in size, shape or color

Question 12

what gestalt principle plays an important role in colour blindness

Answer 12

similarity

Question 13

what test is used to test colour blindness/defiency

Answer 13

Ishiara test

Question 14

what does tthe Ishihara test entail

Answer 14

the test comprises of a series of images made up of coloured dots, to read the numbers, the viewer needs to be able to group the similar colours together

Question 15

proximity

Answer 15

the tendency to percieve the parts of a visual stimulus that are close together, rather than spaces far apart as belonging to a group

Question 16

when is proximity useful

Answer 16

when you need to make sense of many stimuli at once
