The working memory is an advance on the short-term memory from the multi-store model as it is concerned with active processing and brief storage of information. For example, whenever we are working on a complex problem (e.g. arithmetic) we use short-term memory to keep track of where we have got to in the problem. It is also more flexible than the multi-store model and is more useful in explaining our ability to tackle verbal reasoning and spatial and reading tasks. This model can also be used to predict ...
