An experiment on memory was performed, in which 16 subjects were
randomly assigned to one of two groups, called "Sentences" or
"Intentional". Each subject was given a list of 50 words. Subjects
in the "Sentences" group were told to form multiple sentences, each
using at least two words from the list, and to keep forming
sentences until all the words were used at least once. Subjects in
the "Intentional" group were told to spend five minutes memorizing
