Computer games, naps, and memory

Playing tetris can interfere with the encoding of long-term memories, so playing tetris right after something bad happens can reduce the post-traumatic stress disorder.

What's not mentioned here is that it follows that playing tetris right after doing something you want to remember might keep you from remembering it as well.

So if you need a study break, take instead of playing video games, take a nap instead, which has been found to help reinforce memories.
