Multi-store Model of Memory Flashcards
How is info encoded into sensory register, it’s capacity and its duration
Encoded through the five senses
Capacity is large
Duration is 0.5 seconds
How does information move from sensory register to STM
By paying attention to jt
How is STM encoded, what is its capacity and duration
Encoded acoustically
Capacity is 7 plus or minus 2 items
Duration is 18-30 seconds
How does information remain in the STM
The maintenance rehearsal loop by repetition of the information
How does information move from STM to LTM
Prolonged rehearsal
How does LTM encode, it’s capacity and duration
Encodes semantically
Capacity is unlimited
Duration is lifelong
How does information move from LTM to STM
Retrieval of the information
Expand on strength that MSM has research support
-HM was left with only his STM after having brain surgery to remove his hippocampus and he could not make any new LTMs
-demonstrates that STM and LTM are separate memory stored located in different parts of the brain
-supports validity of the model
H: case study of one unique individual, cannot generalise to the wider population so tells us little about different stores
Expand on limitation that the MSM may be an oversimplified model
-KF was a patient with amnesia whose STM for digits was very poor when they read them out loud to him(verbal) but recall much better when he was able to read the digits to himself (visual)
-suggests STM is split into visual and verbal stores , MSM an incomplete model of memory
H:case study, may tell us little about whether STM is one or two stores
Expand on limitation that model is supported by research lab studies
-test memory using artificial tasks eg word lists, random numbers
-tasks lack mundane realism meaning they are not reflective of real-life memories which are more complex and meaningful
-therefore the research that supports the model lacks external validity thus reducing the validity of the model in explaining how we process memories
