Multi Store Model Flashcards
1
Q
What are the threes stores in MSM?
A
Sensory Register
STM
LTM
2
Q
What are the features of Sensory Register?
A
- all stimuli from environment including 5 sense pass into the sensory register
- duration last a fraction of a second
- very little that pass into the sensory register passes further to the STM unless you pay ATTENTION
3
Q
What are the features of STM in MSM?
A
- limited capacity of 7 plus or minus
- encodes acoustically
- Baddeley notice any mistaken words recalled are due to acoustic encoding e.g. any word that sound the same the list may contain bare but accidentaly recalled stare
- duration is between 18 - 30 seconds
4
Q
How can duration of STM be extended?
A
- Duration is 18-30 seconds but maintining rehearsal will retain it long enough in STM
- practicing this rehearsal will also pass into LTM
5
Q
How does the MSM have application to society?
A
- application to society to improve memory
- limited capacity of STM can be extended by ‘chunking’
- can be used for students when learning and recalling lengthy concepts
5
Q
How does patient HM support the MSM?
A
- Patient HM memory explains the MSM
- STM was intact but LTM was damanged
- demonstrates STM and LTM stores are seperate/independent to each other
5
Q
How is MSM good for psychological methods and psychology developing over time?
A
- MSM was useful in it’s time but some aspects were not supported
- MSM changed process of memory e.g. development and improve of the STM
- combine the old (MSM) with newer (WMM) together to have a deeper understanding of behaviour
6
Q
How does Patient KF weakens the MSM?
A
- Patient KF got into a motor cycle accident
- Struggled with verbal information but his visual information was intact
- Shows there’s different stores in STM, not just one unit storage system
- Supports the imporved WMM of STM having 3 limited capacity stores
7
Q
What brain scanning techniques was used and how they backed up the MSM?
A
- used MRI scans to show parts of the brain
- Shows hippocampus is active when using your LTM
- Shows prefrontal lobes is active when using STM
- They back up the existence of different stores for different memories
8
Q
Why being reductionist is a weakness of the study?
A
- reductionist simply very complex phenomenon and reducing it down to simple concepts
- more complex than just three stores in reality
- Against the phenomenon why patient KF verbal information was damanged but visual information was intact
9
Q
Why does Miller Magic 7 plus or minus support the MSM?
A
- found that STM struggles to hold more than 9 items
- WMM or STM contains a temporary store holding a limiting capacity
- able to hold certain amount of infomation before decay occurs
10
Q
Weaknesses of MSM?
A
- Reductionist
- Contradicts studies e.g. WMM which also supports patient KF
11
Q
Stregnth of MSM?
A
- Application of understanding to benefit society to improve memory
- Support in brain scanning
- Support from Miller’s magic 7 plus or minus
