“Researchers also sometimes find it useful to distinguish between recall memory, which is what you can remember spontaneously—the kinds of things you know when you do a general knowledge quiz—and recognition memory, which is where you are a bit hazy on the substance but can recall the context. Recognition memory explains why so many of us struggle to remember the contents of a book but can often recall where we read the book, the color or design of the cover, and other seeming irrelevancies. Recognition memory is actually useful because it doesn’t clutter the brain with unnecessary details but does help us to remember where we can find those details if we should need them again.
