* Have you ever tried to remember song lyrics with the melody removed? Or tried to recall song lyrics without humming the tune to yourself/singing it? Some people can't even recall the order of the alphabet without the song.
* Or had to mime entering in a telephone number on an invisible phone in order to recall a number?
* How about moving your fingers when trying to recall a web address?
* The above two are actually examples of procedural memory, or, colloquially, "muscle memory." It's what happens when you perform a specific action the same way so many times that the brain eventually just gives that particular action its own subroutine, so you don't have to consciously think about doing it anymore.
* Have you ever tried to remember why you went to a particular room by going back to a room where you knew? Often justified or subverted in that the objects or situation that made you go to the other room in the first place may still be there. Also subverted by the way your brain classifies short-term memory: it classifies memory by location and doors triggers in your mind a change of location, so you forget almost everything from the other room unless you go back.
* Being able to play certain drinking games only while drunk/drinking such as [[http://en.wikipedia.org/wiki/Quarters_%28drinking_game%29 Quarters]] or [[http://en.wikipedia.org/wiki/Baseball_%28drinking_game%29 Baseball]].
* Often invoked as "study aids" for students. This is why, among other things, you're supposed to be sitting at a desk as you study the material -- so you can remember the material when you're sitting at a desk for the test. Many teachers also recommend studying in conditions that will exist during the exam. Set a time limit equal to how long you'll have on the exam. Use the exact same pencil. Depending on if the school allows it, you can even go to the classroom and sit in the seat you'll take the exam in and study there.
* On a related note, you're supposed to only use your bed for sleeping[[note]]and sex, of course[[/note]] because if you try studying in bed, you'll find yourself getting sleepy because you've strongly conditioned yourself to associate your bed with sleep. This works both ways: some people have problems with insomnia because they've stopped being conditioned to associate their bed/bedroom with sleep. The remedy for this is to move things like computers, TVS, and exercise equipment out of the bedroom and to minimize non-sleeping time spent there.
* This is also why is not a good idea to stoke yourself up on coffee or energy drinks to cram in your revision, as you won't remember it until you're stoked up on coffee or energy drinks -- probably not a good idea when you're about to go into an exam.
* Studies have shown that smells are also quite good at evoking memories. So study while wearing a ''highly unique'' perfume and then wear it again the day of the test. Legend has it the ancient Greeks were fond of rosemary.
* Averted with performance under extreme stress. It used to be approached under two theories: learn the action normally and then apply stress ''versus'' learn action under stress. Extensive research has proven beyond a shadow of a doubt that the former is a far better way. In the book ''Extreme Fear'', the author goes into the psychology, but essentially your brain shuts down too much in panic mode and focuses only on what it knows will work for it to learn successfully while under duress. So learn calmly, and then introduce distractions.
* There are people who become used to listening to a certain noise at night find it harder to get to sleep if it stops.
* Most men, when teaching how to tie a tie, must stand behind the person they're helping, because [[DamnYouMuscleMemory that's the only way they can remember how the knot goes.]] The opposite can true for women: because they're more likely to learn by tying someone else's tie, if they have to wear a tie themselves[[note]]for instance, some restaurant uniforms call for ties for both waiters and waitresses[[/note]], they [[DamnYouMuscleMemory essentially have to re-learn how to do it]].
* Many basketball players have a short ritual before shooting a free throw-- usually bouncing the ball a certain way-- in order to trigger their muscle memory.
