Why does walking through doorways make us forgetthings?
Thanks forasking. Have you ever walked into your livingroom, kitchen or bedroom and completely forgotten what you went there for in the firstplace?
That happens to most people from time totime, but it can be pretty annoying and a little unsettlingtoo.
You might start wondering if you've got memoryproblems.
Well, this mental block phenomenon actually has aname, the doorwayeffect.
Has it been studied byresearchers?
Yes, and most notably through a series of studies run by Gabriel Redvansky and his colleagues at the University of Notre Dame in theUSA.
The findings were published in the quarterly Journal of Experimental Psychology in2011.
Study participants had to navigate real or virtualenvironments, picking up items as they went along and moving from one room toanother.
They were quizzed by the research team at random intervals and a clear patternemerged.
The participant's memory performance was worse after walking through adoorway.
So what's actually going on in the brain at that specificmoment?
For now there's no definitive proof as to what causes the doorwayeffect, but it seems that when we move from one room toanother, a mental process called event updating kicksin.
The brain removes information linked to the previous environment and starts to focus on the new oneinstead.
The doorway itself is referred to as an eventboundary, and the same thing can actually happen in other scenariostoo, like switching from one browser window to another or when another person enters the room you'rein.
Should I be worried if it happens tome?
Absolutelynot. As I mentioned earlier it happens to mostpeople.
Justassured, experiencing the doorway effect doesn't mean there's any issue with yourmemory, intelligence or cognitivefunction.
It's a normal brainfunction, which means that your brain is dividing things up in a logicalway.
It's like our mind is cleaning the slate when moving from one environment to thenext.
But of course it can be inconvenient if the doorway effect happens when you're in arush, or causes you to forget somethingimportant.
A few tips may help prevent it happening to you toooften.
If you're going somewhere with a specific goal inmind, take an object with you which will remind you of that goal when you getthere.
For example if you're going to the bedroom to look for apen, take your notepad.
Another simple trick is going back to the room you were ininitially.
That may well jog yourmemory, even thinking about the previous environment is sometimesenough.
