Recap the KF Case Study by Shallice and Warrington (1970) and explain how this also supports the Working Memory Model.

The story of KF, a man who suffered a motorcycle accident which caused damage to his left parietal occipital region of the brain, is a story that caught the eyes of Shalice and Warrington(1970). After his accident, KF showed a very poor digit span(short term), but could remember 10 word sequences and even remember them some months late. This contradicted the Multi-Store model as it predicts that a STM is required to transfer information into the LTM, and support this Working Memory model.

The Working Memory model proposed by Baddeley and Hitch(1974) shows that STM and LTM are more complicated than the Multi-Story model proposed, instead, each containing different components. This model proposes that LTM is comprised of 3 different types of LTM, episodic(memories of events), procedural(knowledge of how to do things), and semantic(general knowledge), as it is understood that there is not only 1 single unit for LTM as memory can be categorised into many different types of knowledge. As well as STM, replacing the name of Short Term Memory, to Working Memory, containing different systems for unique processing different types of information. Working Memory includes, Central Executive, Phonological Loop, Visuo-Spacial Sketchpad, and Episodic Buffer.

KF and his accident, support the Working Memory model as his STM was no longer intact but he still managed to send information to LTM, supporting the claim of Working Memory that there are different systems within the working memory(STM), meaning that when one system is damaged, another system can still transfer a certain different type of memory to the LTM.
