ABSTRACT
One clear and anticipated criticism revolved around the visual/spatial component of working memory that Alan D. Baddeley and Graham Hitch proposed. Many aspects of this visual/spatial system was undefined and then questioned after "Working Memory" was published. After publication of the 1974 text, Baddeley quickly changed the name of the visual/spatial component to the visuo-spatial sketchpad. He believed that information was stored spatially in this component, but he accepted Robert Logie's findings and concluded that the sketchpad can handle both visual and spatial information and does so separately. Baddeley incorporated the findings of Logie, Meredyth Daneman, Patricia A. Carpenter, and others into newer conceptualizations of working memory. That should not be surprising, given the tentativeness with which Baddeley and Hitch first proposed the model in 1974. He seems willing to incorporate the findings of other researchers when they add to the Baddeley–Hitch multicomponent model.
