WORKING MEMORY MODEL.
What is the WMM?
-
-
- The WMM is concerned with the 'mental space' this sis active when we are temporarily storing and manipulating information.
- For example:
When working on a arithmetic problem or playing chess.
- The WMM consists of four components.
Central Executive.
-
- The function of the CE is to direct attention to particular tasks
- They allocate the brain's 'resources'.
- The CE has a very limited capacity and can't attend to toom many things at once. It has no capacity for storing data.
Phonological Loop.
-
-
- It has a limited capacity.
- It deals with auditory information and preserve the order of information.
- Baddeley in 1986 described it 'like an inner ear'.
- It is an 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 maintence rehearsal
Visuo-spatial Sketchpad.
Athletics rely on efficient visuo-spatial sketchpad in working memory. For example, Wayne Gretzky a hock player scored a goal by hitting the puck so it bounced off the goalie's back. He was able to visualise the spatial relationship between objects that were not in motion.
-
- Visual information is temporarily stored here.
- Visual information is what things look like.
- Spatial information is the physical relationship between things.
Loge 1995 suggested that it could be divided into:
- A visual cache which stores information about visual items ie: coloue and form.
- An inner scribe which stores the arrangment of objects in the visual field.
Episodic Buffer.
It is added to the model to explain why some patients with amnesia can remember passages from a book when tested despite have no long term recall.
- It is a general store.
- It is an extra storage system.
- It integrates information from the CE, phonological loop and visuo-spatial sketchpad.
- It maintains a sense of time sequencing.
- Simply it records evens that are happening and sends information to the LTM.
