18
Q

what are the main ideas of the hierarchical modal model

A

-discrete stages of memory
-attention and rehearsal required for long term memory
-serial processing steps

19
Q

describe the stages involved in hierarchical model

A

sensory input- enters the sensory register
attention
short term storage
rehearsal
long term storage

20
Q

who proposed the working memory model

A

Baddely and Hitch

21
Q

why is the working memory model different from STM

A

it operates on memory content, but also sensory information and retrieved information

22
Q

what are the main parts of the working memory model

A

central executive, visuospatial sketchpad and phonological loop

23
Q

what brain area is associated with working memory

A

supramarginalgyrus

24
Q

what does explicit memory involve

A

events
facts
relationships

25
Q

what does implicit memory involve

A

priming
conditioning
habituation
sensitisation
procedural

26
Q

how is procedural learning measured

A

sequences of flashes associated with number
ppts tap the number as it appears

27
Q

what was found about procedural learning

A

reaction times to the repeating sequence becomes faster compared to random sequences, even with no knowledge a pattern exists.

28
Q

what is procedural learning encoded by

A

the basal ganglia

29
Q

define priming

A

refers to a
change in the response
to a stimulus, or in the
ability to identify a
stimulus, following prior
exposure to that
stimulus

30
Q

what is conditioning

A

associative memory
unconditioned stimulus paired with conditioned stimulus
unconditioned response elicits conditioned response

31
Q

what is anterograde amnesia

A

memory loss for the future - inability to learn new things

32
Q

what is retrograde amnesia

A

memory loss for the past

33
Q

what are the findings of patient HM

A

hippocampus removed as epilepsy treatment
resulted in anterograde amnesia (episodic memory)
residual memory still in tact

34
Q

how is Korsakoff’s syndrome characterised

A

problems learning new information, inability to remember recent events and long-term memory gaps

35
Q

what brain areas are damaged by Korsakoff’s syndrome

A

dorsomedial nucleus
mammillary bodies

36
Q

what happened to patient EE

A

surgery affecting left superior temporal and left inferior parietal cortex
resulted in selective short term memory deficits

37
Q

what is patient EE used to critique and why

A

modal model of memory - long term memory is still in tact

38
Q

what other forms of memory can be spared with hippocampal damage

A

familiarity

39
Q

how is familiarity tested

A

patients presented with word and then again one hour later
asked to indicate confidence in words that had already been presented

40
Q

How do we study medial temporal lobe involvement in
encoding of familiarity, source (episodic) memory, and
their retrieval

A

-a technique to measure brain activation
-a behavioural test that separates different memory forms

41
Q

what is the experimental design for involvement of hippocampus in encoding

A

encoding - animacy or size judgment
retrieval - recognition and source memory (colour of word)

42
Q

what are the findings of familiarity

A

found to be stored in the entorhinal cortex

43
Q

how is confidence related to encoding

A

the confidence of recognition of an item correlates with activity in the entorhinal cortex
