Working Memory Model
Fichas del conjunto (3)
- 1The working memory modelThe working memory model was proposed by Baddeley and Hitch (1974) and aimed to offer an explanation for the processes involved in STM, and to look at it as an active, multi-component system rather than a unitary store
- 2The Central ExecutiveThe central executive is responsible for monitoring and coordinating all other components of the STM, the 'slave' components and directs attention to particular tasks
The central executive however, has no storage capacity - it is used in concentration on a task but is unable to store any of the information itself - 3The phonological loopThe phonological loop deals with auditory information and preserves the order of information. It has a limited storage capacity.
It was later subdivided into the phonological store and the articulatory process (Baddeley, 1986)
The phonological store is responsible for storing information is speech based form, though has a limited duration of a few seconds
The articulatory process performs maintenance rehearsal of the auditory information held in the phonological store in order to prevent decay. It has a limited capacity and is only able to hold 2 seconds worth of sounds so can hold more short words than long words - word length effect.
