The study focused on ‘working memory’, that part of our mind which refers to the temporary storage of information that still allows us to pay attention and manipulate it. Some believe that working memory is separate to any of our other memory storages, many believe that working memory is simply that part of our long-term memory that we can currently access.
A recent study suggests that merely glancing from left to right (the traditional “shifty look” of spies and sneaks) can boost memory power and help people differentiate between real and imagined memories. Moving the eyes up and down had no such effect. The trick may work because the specific left/right eye movement engages both the left and right hemispheres of the brain at the same time. As little as 30 seconds of the activity could be enough to help you remember where you left your wallet, or the number sequence needed to deactivate that bomb.
