Editing Atkinson–Shiffrin memory model (section)

===Division and nature of working memory===
Baddeley and Hitch have in turn called into question the specific structure of the short-term store, proposing that it is subdivided into multiple components.<ref name=BaddeleyHitch1974 /> While the different components were not specifically addressed in the original Atkinson-Shiffrin model, the authors do note that little research has been done investigating the different ways sensory modalities may be represented in the short-term store.<ref name=AtkinsonShiffrin1968 /> Thus the model of working memory given by Baddeley and Hitch should be viewed as a refinement of the original model.
