Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in 1974, in an attempt to present a more accurate model of primary memory (often referred to as short-term memory). Working memory splits primary memory into multiple components, rather than considering it to be a single, unified construct. [1]
In 1974, Baddeley and Hitch [5] introduced and made popular the multicomponent model of working memory.This theory proposes a central executive that, among other things, is responsible for directing attention to relevant information, suppressing irrelevant information and inappropriate actions, and for coordinating cognitive processes when more than one task must be done at the same time.
Alan David Baddeley CBE FRS (born 23 March 1934) is a British psychologist. He is known for his research on memory and for developing the three-component model of working memory . He is a professor of psychology at the University of York .
Baddeley and Hitch's model of working memory. In 1974 Baddeley and Hitch [11] introduced the multicomponent model of working memory.The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial ...
Baddeley and Hitch's 1974 Model consists of three components; one main component, the central executive and two sub components, the phonological loop and the visuospatial sketchpad. [50] The central executive's primary role is to mediate between the two sub-systems. The visuospatial sketchpad holds information about what we see.
Baddeley and Hitch introduced the model of working memory in 1974. Through their research, they contributed more to help understand how the mind may process information. They added three elements that explain further cognitive processes. These elements are the central executive, phonological loop, and the visuo-spatial working memory. [10]
This loop, proposed by Baddeley and Hitch, represents a system that is composed of a short-term store in which memory is represented phonologically, and a rehearsal process. This rehearsal preserves and refreshes the material by re-enacting it and re-presenting it to short-term storage, and subvocalization is a major component of this rehearsal ...
The Working Memory Model (Baddeley and Hitch, 1974, updated-2000) Many models of working memory have been made. One of the most regarded is the Baddeley and Hitch model of working memory. It takes into account both visual and auditory stimuli, long-term memory to use as a reference, and a central processor to combine and understand it all.
