The idea
More recent work places working memory capacity nearer four items, plus or minus one, when rehearsal and chunking are controlled.
In practice
With rehearsal blocked, performance falls to roughly four items regardless of how many are presented.
Where people slip
The lower figure is not a correction of Miller's data. It measures the capacity after strategies are removed.
