Articulatory Rehearsal Loop
Articulatory rehearsal loop is one of the low-level assistants. It is hypothesized to be part of the working memory system.
Articulatory rehearsal loop draws on subvocalized speech, which serves to create a record in the phonological buffer.
Materials in the phonological buffer then fade, but can be refreshed by another cycle of covert speech, with this cycle initiated by working memory's central executive.
Baddeley's model posits an articulatory rehearsal loop in which to-be-remembered materials are subvocally repeated. (2 points). If all the items in a list can be repeated before any decay, then all of them can be remembered. But items will decay in about 2 to 3 seconds. If it takes longer to rehearse the list than this 2 or 3 second decay time, then some items will decay.
For example, names of letters are very long in Welsh but they are very short in Chinese. According to Baddeley's Working Memory model, Welsh speakers will be able to remember more letters (letter span) than Chinese speakers.
Since Welsh words are longer than Chinese words, fewer Welsh words can be rehearsed in the 2 to 3 second decay time, so fewer will be recalled.
