Studies show that where you learn something has an effect on your ability to recall the information at a later date. In particular, your ability to remember something is improved if you learn the information in the same or similar location that you will recall it. This is because the context in which you learn the material serves as a landmark for your memory.
To use this to your advantage, you should study your subject in the location where you will be expected to recall it. For example, if you are studying for a test, you could study the material in the same classroom (or similar classroom) where you are going to be tested. If you are memorizing lines for a play, you could do it in the theater where you will be performing.
If you don’t know where you will be expected to recall the information, or if you can’t replicate the environment, then you should try to study the material in a variety of different places so you don’t get tied to one particular location.
Studies also show that your body position affects your accuracy at recalling information. So, if you are going to be sitting down while taking your test, it might be a good idea to be seated when you study for it, as opposed to lying down.
