16．Why Does Walking through Doorways Make Us Forget？We've all done it．Run upstairs to get your keys，but forget that it is them you're looking for once you get to the bedroom．Open the fridge door and reach for the middle shelf only to realize that we can't remember why we opened the fridge in the first place．
We can understand those temporary moments of forgetfulness may be more than just an annoyance．Although these errors can be embarrassing，they are also common．It's known as the"Doorway Effect"，and it shows some important features of how our minds are organized．Understanding this might help us accept those temporary moments of forgetfulness as more than just an annoyance．
The Doorway Effect occurs when our attention moves between levels，and it reflects the trust in our memories---even memories for what we were about to do---on the environment we're in．
Imagine that we're going upstairs to get our keys and forget that it is the keys we came for as soon as we enter the bedroom．Psychologically，what has happened is that the plan （"Keys!"） has been forgotten even in the middle of carrying out a necessary part of the strategy （"Go to bedroom!"）．Probably the plan itself is part of a larger plan （"Get ready to leave the house!"），which is part of plans on a wider and wider field （"Go to work!"，"Keep my job!"，"Be a productive and responsible citizen"，or whatever）．Each field requires attention at some point．Somewhere in controlling the complex levels the need for keys suddenly comes into mind．
Our memories，even for our goals，are planted in webs of connections．That can be the physical environment in which we form them，which is why revisiting our childhood home can bring back a flood of previously forgotten memories，or it can be the mental environment---the set of things we were just thinking about when that thing suddenly comes into mind．
The Doorway Effect occurs because we change both the physical and mental environments，moving to a different room and thinking about different things．That hurriedly thought-up goal，which was probably only one plate among the many we're trying to spin（旋轉），gets forgotten when the context changes．
