The Working Model of Memory
Central Executive
Very limited capacity and can be overloaded by too much information and too many tasks. The central executive therefore allocates work to the other stores to free up its own processing capacity
Controls our attention, overseas memory tasks and allocates work to the other parts (slave system) as well as controlling the flow of information to and from the LTM
Control system
Phonological loop
It has two parts: the storage system and the processing system
The storage system is the phonological store which allows acoustically coded items to be passively stores for a brief period
The processing system is the articulatory control system which allows repetition of sounds in the phonological store to prevent rapid decay of the information
Stores and processes speech based sounds for a short period of time
Baddeley described the articulatory control system as a 'tape loop of a tape recorder' with a two second duration
The articulatory control system also codes visual information to verbal information
Visuo-spatial sketchpad
Stores visual and spatial information (information about physical arrangements of something) for a short duration (decay is rapid without rehearsal)
It has two parts: the storage system and processing system
The storage system is the visual cache (stores information about shape and form)
The processing system is the inner scribe (which processes information about position in space)
Coding may be visual, spatial and even kinaesthetic (movement)
Episodic buffer
Prepares information for storage
It combines information from the LTM for use in the working memory
Combines information from different sources into episodes for storage
Each part of the Working memory has a limited capacity. If a person has to do two tasks at the same time which uses one of the systems, it may become overloaded because the demand exceed the processing capacity. On the other hand, the two tasks require different systems then they are less likely to be overloaded and the person can comfortably do the two tasks- 'multi-tasks' at the same time
