Q

associations

A

clusters of abilities or tasks that patients cannot do

21
Q

dissociations

A

tasks that have not been affected

a patient who is impaired at one task but normal at another

22
Q

but to test whether these processes involve different parts of the brain , a

A

double dissociation task - 2+ patients with opposing deficits

23
Q

what does double association tasks tell us

A

that 2 functions involve separable

24
Q

modularity

A

our cognitive processes are reduced down into separate modules

25
Q

what do multiple modules do

A

interact to result in a particular function or behaviour

26
Q

single case studies assumptions

A

caramazza 1986

fractionation assumption , transparency assumption and universality assumption

27
Q

fractionation assumption

A

damaging part of the brain affects specific modules

28
Q

transparency assumption

A

damaging part of the brain subtracts from a process

29
Q

universality assumption

A

all brains are similar - same architecture, processes

30
Q

phineas gage

A

metal rod pierced through orbitofrontal area = massive personality change

31
Q

conclusions of phones gage

A

frontal lobes are involved in personality

32
Q

HM

A

studied by Milner
brain surgery to control seizures
hippocampus removed
severe memory problems

33
Q

retrograde amnesia

A

problem in remembering past events

34
Q

anterograde amnesia

A

difficulties in learning new information

35
Q

HM dissociation

A

able to remember things up to 16 years old
had a dissociation with STM
but intact procedural memory- improved performance on normal mirror drawing Task

36
Q

Clive wearing

A

STM impaired
procedural memory intact
hippocampus is important for forming memories

37
Q

memory consolidation

A

taking a new memory and transferring it into the LTM system so that its retained

38
Q

HJA

A

Suffered from a stroke=occipital lobe damage= visual problems
unable to recognise objects = visual agnosia
but intact memory TO copy pictures
problems perceiving the whole object

39
Q

what is spatial neglect

A

failure to notice things on one side of the space

40
Q

spaital neglect is the result of damage to the

A

parietal and temporo- parietal junction - usually right hemisphere

41
Q

assessment of spatial neglect

A

drawing and copying tasks

bisection and cancellation tasks

42
Q

can the patients see on the neglected side

A

often have normal visual field- no visual field loss

not really aware of their problem - doesn’t stop them

43
Q

Riddoch and Humphreys 1983

A

patients can pay attention if cued to the neglected side

call out number at the end of the line - able to dissect line correctly

44
Q

is neglect person centred or object centred

A

asked patient to draw an image = space centred

object centred= able to perceive the whole thing but only drawn the right side of each object

45
Q

what does neglect us tell us

A

right hemisphere plays an important role in attention

46
Q

opponent processor model

A

kinsbourne
LH is pulling attention to the right
RH is pulling attention to the left
If damaged - undamaged hemisphere dominates attention

47
Q

aphasia

A

inability to comprehend or produce speech

48
Q

Broca aphasia

A

patient tan - able to understand speech but had trouble p producing speech

49
Q

wernicke aphasia

A

can produce speech but had trouble understanding
