Working memory is a part of the human memory system with limited capacity. The work of working memory consists of temporarily holding information to be processed. Working memory refers to the storage of information without manipulation. Working memory capacity is generally considered to be a limited capacity. Miller in 1956 suggested the “magic number seven” as the capacity of working memory. He called the elements "chunks", he claimed that the information capacity of young adults is about seven chunks and he said that the elements do not matter, they are numbers, letters, words or any other category, but later research found that category is important, ability depends. on the category of pieces, for example eight for numbers, seven for letters and six for words.

For example, Daneman and Carpenter invented the "gap reading" task in 1980. Subjects typically read sentences between two and six, then they try to remember the last word of the sentences, then they repeat the words in the good order. Regarding the effect of aging on working memory, working memory capacity gradually decreases as we get older, of course after childhood, because working memory capacity gradually increases over the course of time. childhood. About the importance of working memory, if we did not have working memory we would not have long term memory either because all the information in long term memory is directed by the working memory. When we're going to talk When it comes to the structure of working memory, there are different models of working memory. The most accepted is therefore the multicomponent model of Baddeley and Hitch. They introduced the multicomponent model in 1974. The first model has three components; the central executive, the phonological loop and the visuospatial notebook. The central executive is responsible for carrying information between the other components and somehow controlling the center. Phonological loop responsible for storing fundamental sounds and repeats itself over and over again. Visuospatial notepad responsible for storing visual and spatial information, the spatial part is responsible for locations. They present this model as a “slave system,” with the central executive being a supervisor and the other two components of the phonological loop and the visuospatial sketchpad being slaves.

Get a Custom Essay In 2000, Baddeley updated the model because his model failed to explain the results of various experiments and he added the fourth component as an episodic buffer. The other model is working memory as part of long-term memory, this model is introduced by Ander Ericsson and Walter Kintchs which they call "long-term working memory" and define as "retrieval structures" . In their model, working memory is not a distinct system from long-term memory. Works Cited Baddeley, AD (2000). The episodic buffer: a new component of working memory?
