Why do we forget things
An interesting article in Scientific American discusses a new insight about forgetting: although the brain contains detailed representations of lots of different events and objects, we can’t always find that information when we want it.
“As this study reveals, if we’re shown an object, we can often be very accurate and precise at being able to say whether we’ve seen it before. If we’re in a toy store and trying to remember what it was that our son wanted for his birthday, however, we need to be able to voluntarily search our memory for the right answer—without being prompted by a visual reminder. It seems that it is this voluntary searching mechanism that’s prone to interference and forgetfulness.”
