Multistore Model Flashcards
What does capacity mean?
How much information a memory store can retain.
What does encoding mean?
The form in which the memory is retained in a memory store.
What does duration mean?
How long a memory store can retain information for.
What is the order of the multistore model?
-Sensory register.
-Short term memory.
-Long term memory.
What is the capacity duration and encoding of the sensory register?
C-Up to 10 items
D-2 seconds or less
E-Acoustically from senses.
What is the capacity, duration and encoding of the STM?
C-5-9 items.
D-Under 30 secs
E-Acousitcally
What is the capacity, duration and encoding of the LTM?
C-unlimited
D-Up to a lifetime
E-semantically
How is information passed from the sensory register to the STM?
By paying attention to something.
How is info kept in the STM?
Maintenance rehearsal.
How is info passed from the STM to the LTM?
Elaborative rehersal.
How is info passed from the LTM to the STM?
Retrieval.
How does HM study support the multistore model?
-Has hippocampus removed so could not transfer memories to the LTM.
-Shows different stores in model.
How does Clive Wearing support the multi store model?
STM is still fully functioning but LTM has deficits and can only hold memories sup to 30 seconds.
-Shows different stores in model.
How does the K.F case study support the multi store model?
-Had a damaged STM.
-Only verbal information was effected.
-Shows different stores in model.
How can brain scans/ MRI’s support the multi store model?
-When remembering new info the hippocampus is active (LTM).
-When making a decision prefrontal lobes are active (STM).
-Shows different stores in the model.
How can Baddeley study support the multi store model?
-Semantically similar words were remembered better- LTM encoded.
-Acoustically dissimilar words were remembered better- STM encoded.
How testable is the theory (strength and weakness)?
Strength:
-Has empirical evidence of brain scans which can show different stores in the model.
Weakness:
-Case studies can be unethical as it is a long process which can stress someone out.
How is the theory useful?
Can explain and help students with revision (rehearsal and maintenance).
-Explains types of amnesia anterograde where people can no longer move info from the STM to LTM and how to help them.
