Working Memory
Working Memory
Working Memory is used to keep information in mind while we manipulate and use this information to complete a task. Alan Baddeley's model proposes four components of working memory.


Visuo-spatial sketch pad
Visuo-spatial sketch pad
- The visuo-spatial sketchpad stores information that is in a visual form.
- It can also process spatial information.


Phonological loop
Phonological loop
- The phonological loop stores speech-like information.
- Can be kept for longer by subvocal or verbal rehearsal (saying the words again & again).
- Such as repeating a telephone number in your head until finish dialling it.


Central executive
Central executive
- The central executive is modeled to coordinate the other parts of working memory & controls where your attention is.
- It controls how information will be stored and manipulated in the other components.


Episodic buffer
Episodic buffer
- This component allows information from the other components to be combined and processed together.
- This allows us to make sense of all information being encountered at one time.
- Information previously stored in long-term memory is also processed here in combination with novel information from the other working memory components.
- The buffer can also send information to long-term memory storage.
Long-Term Memory vs Working Memory
Long-Term Memory vs Working Memory
Although long term memory and working memory are very different, their interaction is the basis of learning.


Long-term memory
Long-term memory
- Storage system.
- Unlimited capacity.
- No expiry date.
- Several sub-types.


Working memory
Working memory
- Manipulates information.
- Limited capacity.
- Holds information only as long as it is being used.
- "Where thought takes place".


Analogies
Analogies
- We can think of working memory as a shoe box. It offers limited space and can break if you add too much to it.
- We can think of long-term memory as Mary Poppins’ bag. You can fit as much as you want there and still be able to walk (or fly!) around.
