In the course of researching for the working memory paper I’m about to submit, I had to read quite a bit on Baddeley’s model of working memory. Overall, it appears to be an example of a decent but incomplete model that, rather than admitting its incompleteness, was extended in such a way that it no longer resembles its former self. The components it proposed as working memory subsystems were split apart into definitively disjoint sub-subsystems that may not even share spatial locality in the brain, casting doubt on the experiments with brain-damaged patients that supported the original model in the first place! The addition of an episodic buffer also appears to render some of these sub-subsystems redundant.
