Broad themes

Question 1

what is bottom up processing

Answer 1

stimuli from the external environment

Question 2

what is top down processing

Answer 2

using existing knowledge

Question 3

what are the 2 types of processing for when we see faces and objects

Answer 3

configural/global processing

featural/local processing

Question 4

what is configural/global processing

Answer 4

processing of a whole face/image
position of features compared to each other
doesn’t matter what you do (blur a face) still recognise it, shows we apply global processing

Question 5

what is featural/local processing

Answer 5

parts of the object are processed

Question 6

what is the study called that focuses on local and glocal processing

Answer 6

Navon, 1977

Question 7

what did Navon 1977 do?

Answer 7

global and local processing
Performance speed was slowed when asked what the small letter was when the large letter differed. However, decision speed was not influenced by the small letters when the large letter was asked to be identified
Global affects local but not visa versa

Question 8

what is serial processing

Answer 8

current process happens before the next can be completed

Question 9

what is parallel processing

Answer 9

2 or more processes happen at the same time
or is it
does it truly mean we’re doing those things at the same time?

Question 10

PP

what must task have no of to ensure they are parallel?

Answer 10

no delays as to ensure participants cant switch to the other task

Question 11

PP

Shaffer 1975

Answer 11

found that will touch typing, once skilled, less attention is required
experts could recite nursery rhymes while touch-typing will less than 10% loss of accuracy.
However,
is it still possible to switch attention between tasks even if one is continuous, skilled typists may see a word and type that word instead of what they were originally typing.

Question 12

what is viewpoint invariant

Answer 12

object recognition does not depend on viewpoint

doesn’t matter what angle looked at from, processes are the same

Question 13

what is viewpoint dependent

Answer 13

object recognition does depend on viewpoint

within category discrimination

Question 14

what are geons

Answer 14

we can construct everything in our world from a set of 36 shapes called geons
complex shapes are several geons connected

Question 15

why do geons make objects viewpoint invariant

Answer 15

because object recognition depends on the identification of geons, which can be identified by various viewpoints

Question 16

how is our knowledge organised

Answer 16

through associative networks which is made up of nodes
The node becomes activated, activation level of node rises when exposed to that node related stimuli.
activation spreads to any concept node related to that word.
the stronger the link between the words, the less activation is needed in future to make them become active.
one node can also inhibit another node .e.g stopping yourself from saying an answer
inhibition is the ability of our associative networks to ‘dumb’ down the link between 2 things.

Question 17

what is visual agnosia

Answer 17

where object recognition is impaired in the presence of normal visual function
can see but cannot recognise visual interpretation

Question 18

what is apperceptive agnosia

Answer 18

fail in perception and hence cannot recognise an object

Question 19

what is associative agnosia

Answer 19

perception occurs bur recognition does not

can see and perceive/copy object but cannot recognise it

Question 20

what is prosopagnosia

Answer 20

cannot perceive faces

Question 21

prosopagnosia

developmental and acquired

Answer 21

developmental- present from birth and is a developmental disorder. Never develop the face recognition system. Tends to run in families as it’s genetic
acquired- from a brain injury, had a typical system before

Question 22

prosopagnosia

what are the 3 inclusionary criteria they must have

Answer 22

difficulty with faces evident in every day life
impairment in at least 2 measures of face familiarity
confirmations of lesions by MRI or CT

Question 23

prosopagnosia

patient PG

Answer 23

young et al 1988

damage to right hemisphere impaired in structural encoding of faces

Question 24

prosopagnosia

patient ph

Answer 24

de haan et al, 1987

could classify faces and non faces but familiarity was chance

Question 25

what is anomia

Answer 25

can perceive face but cannot retrieve name

Question 26

what are the 4 stages for face processing

Answer 26

structural encoding
face recognition
person identification
name generation

Question 27

akinetopsia

Answer 27

cannot perceive motion

damage in V5/MT area
