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.
Baddeley was the director of the Cognition and Brain Sciences Unit, a branch of the UK Medical Research Council, based in Cambridge, from 1974 - 1997. [18] He was elected a Fellow of the Royal Society in 1993 [ 19 ] and in 1996, was elected a Foreign Honorary Member of the American Academy of Arts and Sciences . [ 20 ]
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 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]

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.
Mental events must occur in the working memory of short term-store. Both working memory and short-term memory are essential to mental events and cognition.According to Lieberman (2021), Baddeley and Hitch (1974) proposed that working memory consists of three distinct subsystems: what are called a phonological loop, a visuo-spatial sketchpad, and central executive.
