    Does walking through doorways cause forgetfulness?

    We’ve all been there: you’ve got a million things you’re trying to get done, you’re running behind, you walk through a door into another room to get something and… wait a minute, what are you looking for again? Son of a…

    According to new research (PDF here) from Notre Dame psychology professor Gabriel Radvansky, passing through doorways actually does cause us to forget things because of the way the brain compartmentalizes information. Doorways, according to Radvansky, serve as “event boundaries in the mind.” The simple act of having to adjust to a new setting takes just enough mental effort to cause a break in short-term memory. “Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized,” says Radvansky.

    Radvansky’s finding is based on a series of experiments he conducted, in both real and virtual environments, using 55 Notre Dame students (31 female) as subjects. The results were published recently in the Quarterly Journal of Experimental Psychology. From a university press release:

    In the first experiment, subjects used a virtual environment and moved from one room to another, selecting an object on a table and exchanging it for an object at a different table. They did the same thing while simply moving across a room but not crossing through a doorway.

    Radvansky found that the subjects forgot more after walking through a doorway compared to moving the same distance across a room, suggesting that the doorway or “event boundary” impedes one’s ability to retrieve thoughts or decisions made in a different room.

    The second experiment in a real-world setting required subjects to conceal in boxes the objects chosen from the table and move either across a room or travel the same distance and walk through a doorway. The results in the real-world environment replicated those in the virtual world: walking through a doorway diminished subjects’ memories.

    The final experiment was designed to test whether doorways actually served as event boundaries or if one’s ability to remember is linked to the environment in which a decision – in this case, the selection of an object – was created. Previous research has shown that environmental factors affect memory and that information learned in one environment is retrieved better when the retrieval occurs in the same context. Subjects in this leg of the study passed through several doorways, leading back to the room in which they started. The results showed no improvements in memory, suggesting that the act of passing through a doorway serves as a way the mind files away memories.
