Does that sound like an accurate memory metaphor? If a chest is archaic, think of a computer. Memories are files we store in our brain, just as we store files in a computer. When we want to remember something, we pull the file out from our brain and review it.
Does that sound accurate? This is not a trick question. Have you made up your mind?

Pretty cool, huh? Pretty scary, too, when you realize that people go to prison based on the memories of eye-witnesses. Further implications of memory are explored in The Psychology of Judgment and Decision Making (available here).
