Working Memory consists of numerous features, but mainly is that it describes short term memory, telling us what the information means, by processing it. Baddeley showed that participants could do different tasks at the same time, which in the case that he was studying, learning digits and verbal reasoning, and therefore he came to the conclusion that short term memory is more complex than the two stage model. He also stated that it was made out of three parts:the phonological loop The phonological loop is where a limited amount of auditory or

speech-based information is maintained and manipulated. It has two inter-connected sub-components: (1) a passive phonological store, and (2) an articulatory rehearsal process. Auditorily presented verbal information gains direct access to the passive store, which retains information in a phonological (sound-based) form. Information in the store is subject to both decay over time (it will remain in the store for only 1. 5 to 2 seconds) and to interference from new information. Loss of verbal information from the phonological store can be prevented by means of saying something

over and over in your head, and with continuing rehearsal the contents of the store could be retained permanently. The articulatory rehearsal process is the part of working memory that you would use when attempting to remember a telephone number that someone has given you whilst you hunt for a pen and paper to write it down. Information in the phonological loop is held in a temporal and serial fashion (i. e. , the information that goes in first comes out first). the visuo-spatial sketchpad The visuospatial sketch pad is where a limited amount of spatially

and/or visually represented information is maintained and manipulated. It is similar in some ways to the articulatory loop, for example, it has the ability to rehearse information. It can loosely be thought of as an ‘inner eye’. the central executive The central executive can be seen as a supervisory system. It allocates attention to incoming stimuli and directs the operation of the other components of working memory. In some ways it is the most important component of working memory, since it is used when dealing with any task of a cognitively demanding nature. Show preview only
