Working memory model Flashcards
1
Q
Who created the WMM?
A
Baddeley and Hitch (1974)
2
Q
What is the central executive?
A
- Controls operation of other components
- Selectively attend stimuli and ignore others
- Limited capacity
- Retrieves information from LTM to help us in everyday lives
3
Q
What is the articulatory process?
A
- Used to think in words
- Limited capacity for verbal rehearsal
- Inner ear
- E.g. memorising a phone number
4
Q
What is the phonological store?
A
- Receives sound information
- Limited capacity for auditory rehearsal
- Inner voice
- E.g. singing a song in your head
5
Q
What is the VSS?
A
- Transfers verbal to visual
- Limited capacity
- Plans visual or spatial tasks
6
Q
What is visual cache?
A
Used in the VSS for form and colour
7
Q
What is an inner scribe?
A
Used in the VSS for spatial relations
8
Q
What is the episodic buffer?
A
- Records events as they happen
- Integrates information from the VSS and PL
- Limited capacity
- Sends information to LTM
9
Q
How does dual tasks effect the WMM?
A
Each component of the WMM has a limited capacity, if two tasks using the same component, the performance on one of the tasks would be worse when performed together
10
Q
What are the strengths of the WMM?
A
- Expands on MSM view that information in STM is mainly auditory and held as a sound - VSS
- When 2 spatial tasks are carried out they are more difficult than doing one spatial task - shows the limited capacity of the VSS
- STM has multiple stores from brain-damaged patients, STM forgetting of auditory information was greater than his visual (he only had a digit span of 1)
11
Q
What are the weaknesses of the WMM?
A
- Only a model of STM - fails explanation of how LTM works
- Lacks validity because they use artificial tasks such as word lists - doesn’t use many senses
- Bertz (1955) criticised the model for not taking musical memory into account - able to listen to instrumental music without it impairing other acoustic tasks, the WMM states the performance would be impaired since
