The multi store model Flashcards
What is a sensory buffer?
Duration: ¼ to ½ a second
Capacity: Larger capacity
Encoding: sense specific
What is STM
Duration: 0-18 seconds
Capacity: 5-9 items
Encoding: mainly auditory
What is LTM
Duration: Unlimited
Capacity: Unlimited
Encoding: semantic
Give a brief explanation of the multi store model and how it works
Info detected by sense organs, enters sensory memory, if attention is paid this enters STM. Info from STM can be transferred into LTM if it is rehearsed. If rehearsal doesn’t happen, info is lost through decay.
What is a case study that supports this model?
Clive Wearing
Describe the case of clive wearing
Received brain damage in hippocampus due to viral infection. He could still use STM and remember things for about 30 seconds, but would then forget it all.
How does the MSM apply to the Clive Wearing case
It suggests he has trouble rehearsing the information so it cannot get into the LTM
What study was done to support this model? (MSM)
Glazer and Cunitz 1966
What did glanzer and cunitz do?
Study in recalling list of words in any order to test STM
What were their findings?
Participants recalled more words at the start and end of the list than in the middle.
What did they conclude?
Found a primary recency effect
What is the primacy recency effect
Primacy words are well rehearsed and make their way into LTM. Recent words are still in the rehearsal loop of STM. Words in the middle are displaced.
Give one strength of the credibility of the study
Case studies like Clive Wearing support this idea. MSM helps explains that C.W fails to rehearse information which prevents them from encoding information in LTM.
What is a weakness of the theory
Reductionist. We know from the working memory model that the STM is much more complex than shown in MSM.
- Multiple aspects of the STM as well as LTM
LTM also isn’t just 1 aspect, Tulvings explanation of the LTM supports this.
What is 1 objection to this theory (weakness)
Case of KF does not support MSM. he was involved in a motorcycle crash. His STM was damaged, couldn’t repeat back more than 2 digits, however he could still add to his LTM.
