Retention
The rule of redundancy. A basic rule of boot camp is to tell you what you are going
to do before you do it, what you are doing while you are doing it, and what you have done
after you have done it. (Richard Saul Wurman, Follow the Yellow Brick Road)
"The power of an odor to stimulate memory, familiar to anybody in whom a whiff
of perfume or cologne has stirred thoughts of a long-lost lover, has proved itself in a
research laboratory."
"College students who smelled chocolate during a word exercise and again the
next day did better at remembering their answers than others denied the memory-evoking
aroma... A follow-up experiment showed that the same odor must be present upon learning
and testing to get a memory benefit. Chocolate and mothball odors worked equally well,
suggesting that a smell's pleasantness does not affect its power to stimulate
memory."
Nothing awakes a reminiscence like an odor. (Victor Hugo)
