how many stores are there in the MMM?
three
1 of 33
what are the the three stores?
sensory register, Short term memory and long term memory.
2 of 33
what two parts is the sensory register divided up into?
iconic and echoic
3 of 33
what type of information is processed by these two parts?
iconic=visual, echoic=auditory
4 of 33
how is information coded in STM?
acoustically
5 of 33
how would you describe the duration vs capacity of the sensory register?
duration=very very short, capacity = very large
6 of 33
what determines whether information is transferred from the sensory register into the STM store?
attention! nothing is consciously stored if we don't notice it!
7 of 33
describe the capacity vs duration of STM
STM has a short duration and a limited capacity (5-9 items)
8 of 33
what is the duration of STM
up to 30 seconds
9 of 33
what is the process called when we repeat information to ourselves in order to remember it?
maintenance rehearsal
10 of 33
how is information transferred from STM to LTM
through prolonged maintenance rehearsal
11 of 33
what is the capacity of LTM believed to be?
potentially unlimited!
12 of 33
how is information coded in LTM
sematically
13 of 33
how to we recall information from LTM
in has to be transferred from LTM to STM through a process called retrieval
14 of 33
are memories able to pass straight from LTM?
no
15 of 33
what evidence supports the multi store memory model?
Baddeleys word experiment showed that STM & LTM are qualitatively different and the way we code stuff for them is different.
16 of 33
what does the msmm suggest in terms of the independence of the STM and LTM stores?
suggests that they are different and independent.
17 of 33
do the studies into coding, capacity and duration of memory support or criticise the MMM?
they support the model.
18 of 33
which cases disprove the theory that there is only one short term memory store?
patients with amnesia sometimes have varying capabilities of performing STM related tasks.
19 of 33
Who is KF?
a patient with amnesia studied by Shallice and Warrington.
20 of 33
what was the critical piece of evidence from shallice and warrington's study on KF?
KF was able to recall information he had read himself but not information that was read to him.
21 of 33
what does the evidence show?
that there must be at least two different STM stores. one for auditory information and one for visual information. (stores not just registers)
22 of 33
what was Craig and Watkin's criticism of the msmm's theory on rehearsal?
the msmm claims that it's just the amount of rehearsal that transfers info into LTM whereas C&W believe that it is in fact the type of rehearsal rather than quantity.
23 of 33
what are the two types of rehearsal that Craig and Watkins identified?
maintenance and elaborative rehearsal.
24 of 33
what do the two types of rehearsal do? according to C&W?
maintenance just maintains the info in STM whereas elaborative transfers it into LTM
25 of 33
how does elaborative rehearsal work?
elaborative rehearsal is when you elaborate on the information that you have; linking it to preexisting ideas therefore coding the info semantically.
26 of 33
why is this a limitation of the msmm?
because its a theory that simply can not be explained by the model.
27 of 33
give an example of one other limitation of the multi store model.
it doesn't account for the fact that there is also more than one type of LTM e.g. procedural, episodic and semantic
28 of 33
what part of HM's brain was removed?
the hippocampus
29 of 33
why did he have the surgery?
to relieve his epilepsy
30 of 33
what were his symptoms?
he could perform STM based tasks very well but had no functioning LTM; he didn't know the date and would forget conversations he'd had an hour previous.
31 of 33
does the case of HM support or criticise the msmm?
supporta
32 of 33
why does it support it?
because it suggests that the STM and LTM stores are separate because he only struggled with issues to do with LTM; not STM
