The working memory model
Used to explain the bit of memory that you are using when you are working
on complex tasks that require you to store information as you go along.
Developed by Buddeley and Hitch who thought STM was not just one store
but a number of different stores.
The components of working memory
The function of this is to direct attention to particular tasks, determining
at any time how resources are allocated to tasks.
Data arrives from senses of LTM
Limited capacity- can't attend to too much at once.
Deals with auditory information and reserves the order of information.
This was subdivided into the phonological store and an articulatory process.
Phonological store holds words you hear
Articulatory process is used for words that were heard or seen. These
words are silently repeated in a form of maintenance rehearsal.
Used when you have to plan a spatial task (like getting from one room to
Visual or spatial information is temporarily stored here. Visual information
is what things look like. Spatial information is the relationship between
Logie suggested that the Visuo-spatial sketchpad can be divided into a
visual cache (store) and inner scribe which deals with spatial relations.
Buddeley added episodic buffer because he realised the model needed a
The phonological loop and Visuo-spatial sketchpad deal with processing and
temporary storage of specific kinds of information.
The central executive has no storage capacity (nowhere to hold its visual
and acoustic information)
The episodic buffer is an extra storage system that has a limited capacity.
