What are Weakness for the Multi store model
Jacobs digit span study was criticised for being outdated
Miller may have overestimated the STM
Peterson used Artificial tasks - Participants were asked to remember meaningless three-letter strings (e.g., XQF, TZR). These are artificial because they don’t resemble real-life information we usually try to remember, like names or stories.
Tulving overestimated the STM
Brain scan studies
Clive Wearing support
What is an advantage for the Multi store model (67)
High external validity
HM CASE STUDY
he could not form any new memories but he was able to learn new skills. This supports the MSM’s idea that short-term memory (STM) and long-term memory (LTM) are separate stores
The MSM proposes that information must be rehearsed in STM to move into LTM. HM’s inability to form new long-term memories after his hippocampus was removed shows that the hippocampus is critical for this transfer process
What is the capacity and duration for the sensory register and how is it coded
Capacity - very high
Duration - Less than half a second
Modality Specific
Coding for STM LTM and SR
STM
18 SEC AVG
5-9 ITEMS
ACOUSTICALLY
LTM
LIFETIME DURATION
LIFETIME CAPACITY HIGH
SEMANTICALLY
SR
LESS THAN HALF A SECOND DURATION
HIGH CAPACITY
research for duration
Peterson and Peterson
ppts were given nonsense syllables and were told to count backwards to prevent rehearsal
STM has a 18-30 sec duration
if we rehearse it enough it moves to the LTM
research for coding
Jacob did similar and different words
different words produced the best recall
research for capacity
Miller digit span task
ppts had to recall sequences of numbers that increased
