How many stores does the Multi-Store Model of Memory have, and what are their names?
Three - sensory register, short-term memory (STM) store and long-term memory (LTM) store
1 of 13
Who proposed this theory?
Richard Atkinson and Richard Shiffrin
2 of 13
What is the sensory register?
The memory store for our senses. Its duration is less than half a second, but they have a high capacity
3 of 13
What is the key process for information to be passed on from the sensory register to the STM store?
Attention
4 of 13
What is the duration, capacity and coding of the STM store?
18-30 seconds, 7+/-2, acoustic
5 of 13
What is the key process for information to be passed from the STM store to the LTM store?
Rehearsal
6 of 13
What is the duration, capacity and coding of the LTM store?
Up to a lifetime, unlimited, semantic
7 of 13
What has to happen for us to be able to recall information from the LTM store?
It has to first be transferred back into STM by retrieval
8 of 13
Which research evidence supports the MSM theory and why?
Baddeley's - clearly shows that STM and LTM are indeed independent of each-other
9 of 13
What did Shallice and Warrington find?
Amnesia patient KF's STM for digits was poor when read to him, but better when he could read them to himself
10 of 13
Why is Shallice and Warrington's findings a limitation of the MSM theory?
It shows that there must be one store to process auditory information, and one to process visual information
11 of 13
Who decided that there is actually more than one type of rehearsal?
Craik and Watkins
12 of 13
What are the suggested two types of rehearsal?
Maintenance rehearsal, maintaining information in STM, and elaborative rehearsal, needed to transfer information to LTM
