Research on eye movement suggests that there are some strange benefits to some eye movements. For example, there seems to be a correlation between eye movement and creativity. And there also seems to be a correlation between eye movement and memory. That’s an interesting finding considering that these eye movements roughly match what you’ll do when you’re reading an actual book. But it’s not the movement you’ll be making when listening to a book on tape, or (in my experience) reading on a computer screen where you tend to move your head not your eyes. Vive la papier!
