The Working Memory Model (Baddeley and Hitch 1974. - Coggle Diagram
The Working Memory Model (Baddeley and Hitch 1974.
how its organised and how it functions. They believed that memory is not just one store but a number of different stores. Meaning that you would do a better job at 1 visual task and one verbal task than completing two visual tasks simutaniously.
Replaced the idea of the STM being a unitary store like the MSM. And focuses on active processing and short term storage of information.
-monitors incoming information, directs attention to tasks meaning it decides what working memory pays attention to e.g if you were driving a car and speaking and something was in the road then CE would direct attention to the driving isn't of the speaking.
problem solving and reasoning
1st slave system- The Phonological Loop
this deals with auditory information and preserves word order- inner ear.
has a limited capacity e.g watching TV an someone starts speaking to you. You will either miss what is on the TV or you will miss what the person is saying this is because the PL can only focus on one verbal thing at a time.
The Phonological store
which holds words that have been heard for 1-2 seconds.
The Articulatory Process
which holds words that have been heard from the store. And silently repeats these words over and over again like an inner voice and it does that until it is no longer needed.
2nd slave system
- The Visuo-spatial sketchpad
Logie (1995) suggested subdivsions:
visuo-cache which is just a store
inner scribe which is for spatial relations it also looks at spatial awareness.
3rd slave system
- Episodic Buffer
this was added by Baddeley in (2000) as he realised the model needed a more general store.
integrates the visual and spatial and verbal information that has been processed by other stores, whilst also maintaining a sense of time seeking. Gives sequence before timing to long term memory. Just like episodic memory they are time stamped.
links working model to long term memory to the wider cognitive process e.g perception. No storage capacity.
extra storage system but limited capacity
integrates information from other areas
