The Working Memory Model Flashcards
what does the working memory model address?
Addresses only one aspect of memory the Short-Term Memory
What is the role of the Central Executive?
- Monitors and coordinates all mental functions in the working memory
What is the role of the Episodic Buffer?
- receives input from many sources,temporarily stores this information and integrates it in order to construct a mental episode of what is being experienced.
What is the role of a phonological loop?
- Codes speech sounds in the working memory, involving maintenance rehearsal(repetition of words again and again).
This is why it is considered to be a loop
What is the role of a visuo-sketchpad?
- codes visual information in terms of seperate objects
What is the role of the Working memory model?
explaination of the memory used when working on a task.
Baddeledy and Hitch(1974) feel like STM is not only one store, but multiple different ones
As when performing a dual task and they both are visual tasks, you will perform less well in them,than if you do it seperately.
- If you do two things at the same time and one visual whereas one invovles sound thers is no interference . You would do them well separately as you would simultaneously.
Suggesting there is two seperate stores, one for visual processing and a seperate store for processing sounds. This is the basis of the working memory model,where the slave systems are organised by a central executive.
What is the function of the Central executive?
To direct attention to particular tasks, determining at any time how the brain ‘resources’ are allocated to tasks.
Data arrives from the senses or from long-term memory. It has a very limited capacity.
Cant attend many things at once and has no capacity for strong data.
What are the three slave systems
- phonological loop
- Visuo-spatial Sketchpad
- Episodic buffer
What is the role for Phonological loop?
deals with auditory information and preserves the order of information
what is the capacity of Phonological loop?
has a limited capacity
Baddeley(1986) has divided this phonological loop into parts:
1) The phonological store holds the words you hear(like an inner ear)
2) A articulatory process, which is used for words that are heard or seen. These words are silently repeated, like an inner voice. This is a form of maintenance rehearsal.
Visuo-spatial sketchpad
- used when you have to plan a spatial task
- Visual/Spatial information is stored here temporarily.
What is visual and spatial information?
visual information- what things look like
spatial information- is the physical relationship between things
Logie (1995) suggested that the visuo-spatial sketchpad can be divided into:
- A Visual Cache, that stores infornation about visual items
- An Inner scribe, that stores the arranegment of objects in the visual held
