 The Working Memory Model was created in 1974 by Baddeley and Hitch. They proposed that the Short Term Memory was made up of several different components instead of being a unitary store (as suggested by Atkinson and Shiffrin in 1968). The K.F study supports this, where it was found that K.F's digit span was extremely low but he had the ability to process and store information, showing a part of his short term memory was still intact whilst another was impaired.

The main component of the model - the Central Executive - has overall control of the store. It can process information from any of the senses (sight, sound, taste etc.) and completes important jobs such as setting targets and correcting errors but is also supported by its two 'slave systems', the Phonological Loop and the Visuo-Spatial Sketchpad.

The Phonological Loop (sometimes known as the 'inner voice'), deals with all auditory encoded items. It is a temporary memory system with limited capacity. Baddeley, Thomson and Buchanan (1975), provided evidence for the Phonological Loop with their research on the 'word length effect'. Two groups of participants were each shown a list of five words and were asked to serially recall them (in the order they were presented. In the first group the words only had one syllable (e.g. car), whereas in then second group, the words had several syllables (e.g. dictionary). It was found that the participants recalled the shorted words better as it took less time to say them – it was thus concluded that the capacity
