Out of Sight, Out of Mind

PerlJedi writes "Researchers at the University of Notre Dame have conducted a very simple study, with some surprising (or at least amusing) results about how our short term memory works. Quoting: 'Sometimes, to get to the next object the participant simply walked across the room. Other times, they had to walk the same distance, but through a door into a new room. From time to time, the researchers gave them a pop quiz, asking which object was currently in their backpack. The quiz was timed so that when they walked through a doorway, they were tested right afterwards. As the title said, walking through doorways caused forgetting: Their responses were both slower and less accurate when they'd walked through a doorway into a new room than when they'd walked the same distance within the same room.'"

Context-switching matters

[Caerdwyn]

Switching contexts is computationally expensive for our brains, and is a lossy procedure. Any techie can tell you that constant interruptions cause bad code because you lose context and the "gestalt" of what you are doing.

It's one of the reasons why I've always insisted upon having at least one guaranteed-uninterrupted (nothing short of "the building's on fire... again") two-hour block of time per day in any tech job I have. If I don't have that, don't complain to me that I write bad code, but DO expect me to gripe about it in my status and my supervisor evaluation.

I would think

I would think this is due to the brain first checking the next room. It being a new place, we probably want to be well aware of the room before being too far in. Thus our attention is taken away from whatever we are thinking about a minute ago.

I'd argue that taking stock of the new room is the biggest of those distractors. There's a lot involved when you have to take stock of "new" territory, and it'd be pretty easy for that to distract you. Even if you're familiar with the room, it takes a moment to verify things are as you left them. We're not all that far removed from needing to figure out if there's something waiting to eat us around every corner.
