working memory discuss
"Discuss the components of working memory." J. Q. Student
Working memory is a structured process that stores information, whilst also allowing the dynamic manipulation of information so that the brain is able to connect in verbal and nonverbal tasks such as reasoning, learning and comprehension. Furthermore, working memory makes information available for further processing. The concept of a working memory stemmed from criticism of Atkinson and Shiffrin’s (1968) multi-store model of memory (MSM). The MSM describes memory in terms of information flowing through a system. First, information is detected by the sense organs and enters the sensory memory. If attended to, this information enters the short-term memory. If rehearsed, information from the short-term memory is transferred to the long-term memory. However, Baddley and Hitch (1974) proposed that the MSM oversimplified the concept of short-term memory, arguing that it was more complex and versatile than a simple unitary system that holds limited amounts of information for short periods of time with relatively little processing. Instead, they proposed an alternative form of short-term memory, called working-memory, which was more complex and multi-component.
This essay details Baddeley’s multi-component model of working-memory, providing evidence for the model as a whole and for the separate components.
Whilst Atkinson and Shiffrin proposed that all information enters a single memory store, namely short-term memory, the multicomponent model of working-memory suggests that there are alternative systems for different information types. Their concept of workingmemory consists of a central executive and two subsystems, which the central executive controls and coordinates. These are the phonological loop and the visuo-spatial sketchpad.
The model proposes that these three components each have a limited capacity, and that they are relatively independent of each other. This leads
