A common short-term memory retrieval rate may describe many cognitive procedures [PDF]

open access: yes, 2014
We examine the relationship between response speed and the number of items in short-term memory (STM) in four different paradigms and find evidence for a similar high-speed processing rate of about 25–30 items per second (∼35–40 ms/item). We propose that
