A new article in Scientific American* claims our brains are wired to forget what we were thinking about any time we walk through a doorway. So when you leave one room in your house with a specific mission to do in another room, only to find yourself standing there befuddled when you reach the new room, it’s not incipient dementia, it’s just the “doorway effect.”
Other interruptions can function the same way, such as someone ringing your doorbell. Our memories purge what we were thinking in order to deal with the new situation. That’s a relief!
