The doorway of forgetting.

Researchers at the University of Notre Dame have found a strange link between forgetting things and walking through doorways:

New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses.

“Entering or exiting through a doorway serves as an ‘event boundary’ in the mind, which separates episodes of activity and files them away,” Radvansky explains.

“Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized.”

The study was published recently in the Quarterly Journal of Experimental Psychology.
