On page 12 of the AS Complete Companion the text says that the central executive component of the Working Memory Model has a ‘very limited capacity’ but later, on the same page the text says the central executive has ‘no storage capacity’. Sounds like a contradiction! But on closer inspection there isn’t a contradiction – of course the the central executive has to have some capacity to direct attention but it has no extra storage capacity. I did double check this with Professor Alan Baddeley, who says ‘I assume that the executive has limited attentional capacity, but does not act as a store. Central storage in working memory is now assumed to depend on the episodic buffer’.

Keep your queries coming in!
