Have you ever walked into a room, and immediately forgotten why you went in there? It turns out that your brain might be hardwired to do this.
In an experiment carried out at the University of Notre Dame, participants were asked to look at a box of objects sitting on one table, and then carry it to another table where they were tested on the contents of the box. The researchers found that subjects were more likely to make mistakes on the memory tests if the trip between tables required them to pass through a doorway.
When I read research articles about things our brains do automatically, I always wonder if there is (or used to be) some important reason behind it. Like most scientists, my first instinct is to think that such behavior is a symptom of latent telepathic abilities.
