Ancient technique can dramatically improve memory, research suggests | Science | The Guardian
After spending six weeks cultivating an internal “memory palace”, people
more than doubled the number of words they could retain in a short time
period and their performance remained impressive four months later. The
technique, which involves conjuring up vivid images of objects in a
familiar setting, is credited to the Greek poet Simonides of Ceos, and
is a favoured method among so-called memory athletes.
